Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

For the sake of understanding the present embodiment, a detailed description will be given of a charging control method for a hybrid vehicle disclosed in the present embodiment.

Referring to a flowchart of a charging control method of a hybrid vehicle shown in fig. 1, the method includes the steps of:

and step S101, acquiring vibration data of the hybrid electric vehicle in real time.

The vibration data includes both vibration values in the hybrid vehicle, such as: vibration value generated by a chassis in the running process of the vehicle, vibration value generated when a sound box plays with large volume, vibration value generated by a compressor in the running process of an air conditioner and the like; also included are the relevant control parameters in hybrid vehicles which can generate vibrations, such as: the sound volume value of the sound equipment, the air volume value of the air conditioner, the running speed of the vehicle, the running road section and the like. In the real-time acquisition of vibration data, the vibration values may be implemented using vibration sensors deployed in the vehicle. These vibration sensors may be deployed in the chassis area as well as in the cockpit. The data collected by the vibration sensor includes amplitude, angle, etc. data, which may be combined with the time of data collection. The vibration data is used as automobile vibration which can be perceived by a user, and the intuitive feeling for the automobile vibration is embodied.

It should be noted that the vibration data acquired at this time mainly comes from vibrations generated by various devices in the vehicle and vibrations transmitted from the chassis while the vehicle is traveling, and does not include vibrations generated by the operation of the engine.

Step S102, determining the operation parameters of the engine corresponding to the acquired vibration data based on the corresponding relation between the preset vibration data and the operation parameters of the engine of the hybrid electric vehicle; the corresponding relation is based on the corresponding relation between different operation parameters of the engine and different vibration data of the hybrid electric vehicle; the vibration value generated under the operation parameter of the engine is not larger than the vibration value corresponding to the vibration data.

The correspondence in this step includes correspondence between vibration values under different operating parameters of the engine and vibration values corresponding to different vibration data, and specifically, the operating parameters of the engine may include: power, torque, rotational speed, etc., and vibration data may include: vibration values, vibration adjustment values, etc. It should be noted that the vibration adjustment value is a relevant adjustment value capable of generating vibration, such as an air conditioning adjustment value, a sound adjustment value, and the like, and when a user adjusts an air conditioner, the air conditioner compressor may generate corresponding vibration; when the user adjusts the sound, the sound will generate corresponding vibration during the playing music. The correspondence includes correspondence between the vibration values and the vibration data under the respective operating parameters, such as: the correspondence of power to vibration value, the correspondence of rotational speed to vibration value, the correspondence of power to vibration adjustment value, the correspondence of rotational speed to vibration adjustment value, and the like. Generally, the higher the value in the vibration data, the higher the corresponding operating parameter of the engine; the lower the value in the vibration data, the lower the corresponding operating parameter of the engine.

The contrast relationship may be represented by a correlation relationship curve, for example, when the relationship curve is used for measuring a relationship between a vibration value and power, the relationship curve is set in a cartesian axis, an abscissa is the vibration value, and an ordinate is the power corresponding to the vibration value. After the vibration value of the hybrid electric vehicle is obtained, the corresponding power can be obtained according to the relation curve, and the vibration value generated when the engine runs under the power is not larger than the vibration value of the hybrid electric vehicle obtained in real time.

In general, the corresponding relation comprises the corresponding relation between the vibration generated by the running of the engine and the vibration acquired in real time in the hybrid electric vehicle, and represents the intuitive feeling of the personnel in the vehicle to the vibration in the vehicle. Therefore, the acquisition process of the corresponding relationship needs to include various scenarios as much as possible, such as: different values of tire pressure, different vehicle movement patterns, different cargo carrying conditions, etc., all affect the corresponding relationship. In the process of acquiring the corresponding relation, the hybrid electric vehicle needs to be arranged in a flat test scene, and the influence of other external vibration on the corresponding relation is reduced.

And step S103, controlling the engine to charge the power battery of the hybrid electric vehicle according to the determined operating parameters of the engine.

After obtaining the operating parameters of the engine, the engine is controlled to charge the power battery of the hybrid electric vehicle by using the operating parameters, and the operating parameters also comprise power, torque, rotating speed and the like. The vibration generated under the operation parameter of the engine at this time is not more than the vibration value corresponding to the vibration data of the hybrid electric vehicle, that is, the operation vibration value of the engine at this time is not more than the vibration value which can be felt by the vehicle occupant in the hybrid electric vehicle at this time, so that the operation parameter of the engine can be changed under the condition that the vehicle occupant does not sense, such as: the power or the rotating speed of the engine is increased to charge the power battery. In this case, the driver does not feel the operation of the engine.

In the process of controlling the engine to charge the power battery of the hybrid electric vehicle by using the operating parameters, the corresponding charging strategy can be determined by combining the charging logic of the hybrid electric vehicle. For example, in a hybrid vehicle in which an engine and a motor output driving force simultaneously, the engine is not only used to charge a power battery, but also used to drive the vehicle to run under the operating parameters of the engine; for a hybrid electric vehicle which is not used for outputting driving force by an engine and is only used for charging a power battery, the engine only charges the power battery under the operation parameters of the engine, the charging efficiency is as high as possible, and the aim is to store more electric quantity in the power battery in the optimal fuel oil rotating speed interval of the engine.

The actual scenario is as follows: when the hybrid electric vehicle runs to a bumpy road section; the engine is controlled to charge the power battery or the charging power of the engine is improved, and the vibration generated when the power battery is charged is covered by the vibration generated when the vehicle jolts, so that the perception of a user on the vibration generated when the power battery is charged is reduced; when a user adjusts the sound box or the air conditioner, the sound box or the air conditioner can bring vibration to the vehicle, and the engine is controlled to charge the power battery or improve the charging power of the engine. It should be noted that the vibration generated when the engine charges the power battery is masked by the vibration generated when the audio or air conditioner is operated. Therefore, in an actual scene, the method can reduce the perception of the user on the vibration generated when the power battery is charged, and can store as much electric quantity as possible in the power battery.

According to the charging control method of the hybrid electric vehicle, provided by the embodiment, the real-time vibration in the vehicle can be associated with the charging process of the engine, so that the vibration generated by the engine when the power battery is charged is covered by the real-time vibration corresponding to the vibration data, the charging scene of the power battery by the engine is increased, and the charging efficiency of the power battery is improved.

In some embodiments, the step S102 of determining the operation parameter of the engine corresponding to the acquired vibration data based on the preset correspondence relationship between the vibration data and the operation parameter of the engine of the hybrid vehicle, as shown in fig. 2, includes:

step S201, if the vibration data is larger than a preset vibration data threshold value, determining a parameter adjusting weight value corresponding to the acquired vibration data based on the corresponding relation between the preset vibration data and the running parameters of the engine of the hybrid electric vehicle; the parameter adjusting weight value is determined based on the ratio of the vibration value generated under different operation parameters of the engine to the vibration value corresponding to different vibration data of the hybrid electric vehicle.

In determining the operating parameters of the engine, it is necessary to adjust the weight values using parameters corresponding to different operating parameters. The parameter adjustment weight value is a proportional parameter and is determined based on a preset correspondence relationship between vibration data and an operating parameter of an engine of the hybrid vehicle. Specifically, the parameter adjustment weight value is determined based on the ratio of the vibration value generated under different operation parameters of the engine to the vibration value corresponding to different vibration data of the hybrid electric vehicle. The parameter adjusting weight value is finally used for adjusting the operation parameters of the engine, and can be understood as engine adjusting parameters corresponding to the vibration data acquired in real time, and after the operation parameters of the engine are adjusted by using the parameter adjusting weight value, the vibration value generated during the operation of the engine is smaller than the vibration value generated by the vibration data acquired in real time.

Step S202, adjusting the current running parameters of the engine according to the parameter adjusting weight value; and determining an operating parameter of the engine corresponding to the acquired vibration data based on the adjusted operating parameter.

And after the parameter adjusting weight value is obtained, adjusting the parameter adjusting weight value and each running parameter of the engine to finally obtain the adjusted running parameter of the engine. These operating parameters likewise include power, torque, rotational speed, etc., in the case of power: after a parameter adjusting weight value corresponding to the power is obtained, multiplying the parameter adjusting weight value by the current running power of the engine to obtain an adjusted engine power parameter; if the parameter adjustment weight value corresponding to the power is larger than 1.0, the current power of the engine needs to be increased, so that the adjusted engine power value is obtained after the current power value is multiplied by the power weight value, and the power battery is charged by the power value.

In a specific scene, the vibration data obtained in real time needs to be compared with a preset vibration data threshold value, and the adjustment of the operation parameters is performed after a certain comparison relation is met. For example, in a scene where the vibration data is a vibration adjustment value, if the vibration adjustment value is an air volume adjustment value of an air conditioner, when it is detected that the air volume adjustment value of the air conditioner reaches a maximum gear, a parameter adjustment weight value of a hybrid vehicle corresponding to the air volume adjustment value is obtained according to the corresponding relationship. In an actual scene, when the condition that the air volume of the air conditioner is adjusted to the maximum gear by a user is detected, the acquisition process of the parameter adjusting weight value is executed, the current operation parameter of the engine is adjusted according to the parameter adjusting weight value, and the engine is controlled to charge a power battery of the hybrid electric vehicle. Finally, the engine is controlled to charge the power battery finally through the air volume adjusting value of the air conditioner on the vibration layer.

As can be seen, in the above embodiment, a judgment condition is added in the process of obtaining the parameter adjustment weight value, and the process of obtaining the parameter adjustment weight value can be executed only when the condition is satisfied; and if the condition is not met, the acquisition process of the parameter adjusting weight value is not executed. Thus, in some embodiments, if the vibration data is not greater than the preset vibration data threshold, the configuration parameter adjusts the weight value to 1.0.

In some embodiments, the step of acquiring vibration data of the hybrid vehicle in real time includes: the method comprises the steps of acquiring a vibration value of the hybrid electric vehicle in a driving cab in the driving process in real time, and acquiring a vibration adjusting value for adjusting the state of a vibration source in the driving cab of the hybrid electric vehicle in real time.

The vibration data includes both a vibration value generated during the driving of the hybrid vehicle and an associated adjustment value capable of generating vibration in the hybrid vehicle. The vibration value mainly comes from jolt generated in the driving process of the automobile; the vibration adjustment values mainly include: volume value of the sound in the vehicle, air volume value of the air conditioner and the like.

The vibration value in the vibration data is mainly acquired through a chassis and acquisition equipment arranged in a cab, and the vibration value acquired in the chassis mainly takes an automobile as a main body and is closely related to the road condition of a road; the vibration value collected in the cab is mainly based on a user and is related to the actual feeling of the driver. A plurality of vibration value acquisition devices are usually arranged, and the acquisition devices in the chassis can be arranged at the positions of an automobile suspension, a crossbeam, an oil tank and the like; the collecting equipment in the cab can be arranged at the positions of an accelerator pedal, a brake pedal, a seat and the like. And the vibration data acquired by the plurality of acquisition devices are subjected to superposition calculation or mutual comparison to obtain a final vibration value.

The following describes an acquisition process of the parameter adjustment weight value with reference to a specific scenario. If the vibration value is derived from the pitching process generated by the vehicle running, the vibration data at this time is the vibration value. For a hybrid electric vehicle capable of positioning, in some embodiments, before determining a parameter adjustment weight value corresponding to the acquired vibration data based on a preset correspondence relationship between the vibration data and an operating parameter of an engine of the hybrid electric vehicle, as shown in fig. 3, the method further includes:

step S301, obtaining route data in a time period from a target time to a current time based on the position data of the hybrid electric vehicle obtained in real time; the target time is a time before the current time.

For a hybrid electric vehicle with a positioning function, position data can be acquired in real time according to the positioning function during the running process of the vehicle, so that the running track of the vehicle is predicted, and further vibration generated by a road in the predicted running track is acquired in advance.

In a specific implementation process, firstly, route data in a last time period at the current moment is acquired according to the position data of the hybrid electric vehicle acquired in real time, and the route data comprises a vehicle running track and vibration data corresponding to the vehicle running track. For example, the target time may be 10 seconds before the current time, and the corresponding time period may be 10 seconds before the current time.

Step S302, matching the route data with preset route sample libraries; the route sample library comprises position data of each route and vibration values generated when the hybrid electric vehicle runs on each route.

After route data are obtained, the route data are matched with each route sample library; specifically, the driving track in the route data of the current moment is predicted to obtain the driving track of the hybrid electric vehicle and the vibration data of the driving track from the current moment to the next moment. In the concrete implementation process, the driving track of the hybrid electric vehicle can be determined by combining map data, wherein the map data comprises the fluctuation information of the road surface, such as road repairing, uneven bumpy road sections and the like, and when the hybrid electric vehicle drives to the bumpy road sections, corresponding vibration can be generated. It should be noted that chassis vibration data generated when different vehicle types run on the same road are different, so that a sample library of each route can be finally generated by acquiring vehicle body chassis vibration data generated when various vehicle types run on the road.

The positioning can be realized only by combining the hybrid electric vehicle, and because the hybrid electric vehicle in the prior art is generally provided with a positioning device for navigation, the position of the road where the vehicle is located can be conveniently obtained in real time, and the specific implementation process is not repeated.

The route sample library comprises position data of all routes and vibration data generated when the hybrid electric vehicle runs, and due to the fact that roads comprise various fluctuating road conditions and height differences exist between the fluctuating roads and the road surface, when the hybrid electric vehicle runs to the fluctuating road surface, a chassis of the hybrid electric vehicle generates corresponding vibration. Therefore, the chassis vibration value generated when the automobile runs on the rough road is obtained according to the height value of the rough road obtained in advance, the chassis vibration value and the height value are corresponding, and the obtained corresponding relation can be simply understood as the attribute of the automobile chassis. For example, when the front wheels traverse a rough road 10 cm above the road surface, the chassis can produce a 1 degree vibratory effect.

Step S303, if the matching is successful, obtaining a vibration value of the next moment of the current moment according to the matched vibration data.

And after the matching is successful, obtaining the vibration value of the next moment according to the matched vibration data. It should be noted that the successfully matched vibration data is essentially a prediction of the vibration generated during the current vehicle driving process, and the current vehicle vibration trend is obtained. After the current vibration data is matched, the chassis vibration value at the next moment of the current moment can be obtained; the next time may be a time 1 second after the current time, a time 10 seconds after the current time, and the like, and may be specifically set according to an actual usage scenario.

After obtaining the vibration value at the next moment, determining a parameter adjustment weighted value corresponding to the obtained vibration data based on the corresponding relation between the preset vibration data and the operation parameters of the engine of the hybrid electric vehicle, wherein the parameter adjustment weighted value comprises the following steps:

and if the vibration value at the next moment of the current moment is larger than the preset vibration value threshold value, determining a parameter adjusting weight value corresponding to the vibration value at the next moment of the current moment based on the corresponding relation between the preset vibration data and the running parameters of the engine of the hybrid electric vehicle.

The vibration value at the next moment is essentially a prediction result of the current vibration value, so that the parameter adjustment weight value of the hybrid electric vehicle corresponding to the vibration value is determined according to the obtained vibration value at the next moment, and finally the power battery of the hybrid electric vehicle is charged in real time in the charging process. Fig. 4 shows a schematic diagram of obtaining the parameter adjustment weight value from the vibration value at the next time. The vibration value at this time is derived from vehicle chassis data, and the vehicle has a positioning function, and can obtain vibration data of a relevant road section from a map. The vehicle running track of the current time interval and corresponding vibration data are obtained by matching the vehicle running track of the current time interval, and if the matched chassis vibration value is larger than a preset vibration threshold value, the corresponding parameter adjusting weight value is obtained based on the corresponding relation between the vibration value and the parameter adjusting weight value, and finally the corresponding parameter adjusting weight value is used for charging the power battery. Specifically, when the vehicle travels to a bumpy road section, if the vibration value generated in the road section on which the vehicle is predicted to travel exceeds a preset vibration threshold value, the operating parameters of the engine are adjusted at the moment of generation of the vibration value for charging the power battery. It should be noted that the vibration value generated by the engine in the current operating parameter is not larger than the vibration value at this time, so that the vibration value generated by the engine during operation is hidden in the vibration value generated during the running of the vehicle.

It can be seen from the foregoing embodiments that a user can implement charge control on a hybrid electric vehicle by predicting a vehicle travel track, a scenario in which an engine performs charge control on a power battery in the hybrid electric vehicle is increased, and the control process is real-time.

The vibration value in the above embodiment is based on that the hybrid electric vehicle can be positioned in real time, and some vehicles without a positioning function cannot use the route sample library for route matching and then prediction. At this time, the vibration value of the current time period is required to be used as the vibration value of the next time period. Therefore, in some embodiments, when the vibration data is a vibration value, determining a parameter adjustment weight value corresponding to the acquired vibration data based on a preset correspondence relationship between the vibration data and an operating parameter of an engine of the hybrid vehicle, as shown in fig. 5, includes:

step S501, determining a vibration value obtained in real time from a target moment to a current moment as a vibration value at a moment next to the current moment; the target time is a time before the current time.

Because the vehicle cannot realize the prediction of the driving track through positioning, vibration values in a period of time need to be summarized, in the specific implementation process, the target time can be the time 1 minute before the current time, and the corresponding time period is the time period 1 minute before the current time.

Step S502, if the vibration value at the next moment of the current moment is larger than a preset vibration value threshold value, determining a parameter adjusting weight value corresponding to the vibration value at the next moment of the current moment based on the corresponding relation between preset vibration data and the operation parameters of the engine of the hybrid electric vehicle.

Taking a vibration value obtained in real time from a target moment to a current moment as a vibration value of the next moment, and judging the vibration value and a preset vibration threshold value; and if the vibration value is larger than the preset threshold value, obtaining the parameter adjusting weight value of the hybrid electric vehicle corresponding to the vibration value based on the preset corresponding relation. The vibration value at this time mainly represents the vibration value generated in the next time period, and in the hybrid electric vehicle without the positioning function, the parameter adjustment weight value corresponding to the vibration value in the next time period is calculated by using the vibration value in the current time period as the vibration value in the next time period, as shown in fig. 6. Summarizing the vibration value curve before the current time, namely the vibration value curve in fig. 6 is a part of a solid line; this portion of the curve is then taken as the vibration curve for the next period, i.e., the vibration value curve in fig. 6 is a portion of the dashed line. The portion of the dotted line is identical to the portion of the solid line, indicating that the vibration value generated in the next period takes the vibration value of the current period. And obtaining a parameter adjusting weight value of the vibration value generated in the next period based on the corresponding relation between the preset vibration value and the parameter adjusting weight value. As shown in fig. 6, in the vibration value curve after the current time, when the vibration value is greater than the preset vibration threshold, the corresponding parameter adjustment weight value is greater than 1.0; and when the vibration value is not greater than the preset vibration threshold value, the corresponding parameter adjustment weight value is 1.0. Although the obtained vibration value in the next time interval has certain hysteresis, the numerical change trend of the vibration value can be reflected to a certain extent. And obtaining a corresponding parameter adjusting weight value, and finally adjusting the parameters of the engine to realize the charging of the power battery. Also, the value of the vibration generated in the operating parameter of the engine at that time is not greater than the value of the vibration at that time.

It can be seen from the above embodiments that a user can realize the charging control of the hybrid electric vehicle by counting the vibration value of the current time period, and a scene of controlling the charging of the power battery by the engine in the hybrid electric vehicle is added, and although the control process has a certain hysteresis, the limitation of the positioning function can be eliminated, so that the application range is wider.

In the above embodiment, the parameter adjustment weight value is obtained by using the vibration value, and the following describes an embodiment in which the parameter adjustment weight value is obtained by using the vibration value. First, describing an air conditioning adjustment value among vibration adjustment values, in some embodiments, when the vibration data is a vibration adjustment value, determining a parameter adjustment weight value corresponding to the acquired vibration data based on a preset correspondence relationship between the vibration data and an operating parameter of an engine of the hybrid vehicle, as shown in fig. 7, includes:

step S701, acquiring an air conditioner adjusting value in vibration adjusting values; the air conditioning adjustment value is used for adjusting the air volume and the temperature of an air conditioner in the hybrid electric vehicle.

In an actual scene, after a user starts the air conditioner and sets the air volume and the temperature of the air conditioner, the compressor of the air conditioner can generate vibration, and the vibration has a certain relation with the air volume and the temperature in an air conditioner regulating value; generally, the larger the air volume in the air conditioning adjustment value, the larger the generated vibration value; the lower the temperature in the air conditioning value, the greater the vibration generated by the compressor.

Step S702, if the air conditioning adjustment value is larger than the preset air conditioning adjustment threshold value, determining a parameter adjustment weight value corresponding to the air conditioning adjustment value based on the corresponding relation between the air conditioning adjustment value in the preset vibration data and the operation parameters of the engine of the hybrid electric vehicle.

If the air conditioner adjusting value is larger than the preset air conditioner adjusting threshold value, the vibration generated after the air conditioner adjusting value is adjusted is larger, a parameter adjusting weight value corresponding to the air conditioner adjusting value is obtained according to the corresponding relation, and the engine is controlled to charge the power battery through the parameter adjusting weight value. And under a specific use scene, a user starts the air conditioner and adjusts the air volume and the temperature, if the adjusted air volume and the adjusted temperature are larger than a preset threshold value, a parameter adjusting weight value corresponding to the air conditioner adjusting value is determined according to the corresponding relation, the operating parameter of the engine is adjusted by using the parameter adjusting weight value, and finally the power battery is charged. At the moment, the vibration value of the engine generated in the charging process under the current operation parameters is not greater than the air conditioner vibration value under the air conditioner adjusting value at the moment, and the vibration generated in the charging process is hidden in the air conditioner vibration.

According to the embodiment, a user can adjust the air conditioner, so that the charging control of the hybrid electric vehicle is realized, and a scene of controlling the charging of the power battery by the engine in the hybrid electric vehicle is increased.

In the following description of the scheme of the acoustic adjustment value in the vibration adjustment values, in some embodiments, when the vibration data is the vibration adjustment value, the parameter adjustment weight value corresponding to the acquired vibration data is determined based on the preset correspondence relationship between the vibration data and the operation parameter of the engine of the hybrid vehicle, as shown in fig. 8, and includes:

step S801, acquiring a sound adjusting value in the vibration adjusting values; the stereo adjustment value is used to adjust audio played in a stereo of the hybrid vehicle.

In an actual scene, after a user adjusts the sound, a loudspeaker of the sound generates vibration, and the vibration and the sound adjustment value have a certain relation. Generally, the larger the acoustic adjustment value, the larger the generated vibration value; the smaller the acoustic adjustment value, the smaller the vibration generated.

And S802, if the sound adjusting value is larger than a preset sound adjusting threshold value, determining a parameter adjusting weight value of the hybrid electric vehicle corresponding to the sound adjusting value based on the corresponding relation between the sound adjusting value in the preset vibration data and the running parameter of the engine of the hybrid electric vehicle.

If the sound adjusting value is larger than the preset sound adjusting threshold value, the vibration generated after the current sound is adjusted is larger, a parameter adjusting weight value corresponding to the sound adjusting value is obtained according to the corresponding relation, and the engine is controlled to charge the power battery through the parameter adjusting weight value. In a specific use scene, a user adjusts the volume value of the sound, if the adjusted volume value is larger than a preset threshold value, a parameter adjusting weight value corresponding to the sound volume value is determined according to the corresponding relation, the running parameter of the engine is adjusted according to the parameter adjusting weight value, and the running parameter is finally used for charging the power battery. At the moment, the vibration value generated in the charging process of the engine under the current operation parameters is not greater than the vibration value generated under the volume adjustment value at the moment, so that the vibration generated in the charging process is hidden in the vibration generated by the sound under the volume adjustment value.

It can be seen from the above embodiment that, the user can adjust the stereo set, so that the charging control of the hybrid electric vehicle is realized, and a scene of controlling the charging of the power battery by the engine in the hybrid electric vehicle is increased.

In some embodiments, the operating parameters of the engine include power of the engine and speed of the engine; adjusting the current operating parameters of the engine according to the parameter adjustment weight values, and determining the operating parameters of the engine corresponding to the acquired vibration data based on the adjusted operating parameters, as shown in fig. 9, including:

step S901, multiplying a parameter adjustment weight value corresponding to the power of the engine by the current power in the current operating parameter to obtain an adjusted power parameter.

The parameter adjusting weight value is obtained through a preset corresponding relation, and the corresponding relation is determined based on the ratio of the vibration value generated under different operation parameters of the engine to the vibration value corresponding to different vibration data of the hybrid electric vehicle. At this time, the operating parameters of the engine include power of the engine and a rotational speed of the engine, and therefore the parameter adjustment weight values include a weight value corresponding to the power of the engine and a weight value corresponding to the rotational speed of the engine.

In the specific implementation process, the parameter adjusting weight value corresponding to the power of the engine is multiplied by the current power in the current operation parameter to obtain a new power value. And on the basis of the current working state of the engine, the power of the current engine is adjusted by using the parameter adjusting weight value to obtain an adjusted engine power parameter.

And step S902, multiplying a parameter adjusting weight value corresponding to the rotating speed of the engine by the current rotating speed in the current operating parameters to obtain an adjusted rotating speed parameter.

Similar to the previous step, in the step, on the basis of the current working state of the engine, the rotating speed of the current engine is adjusted by using the parameter adjusting weight value, so that the adjusted rotating speed parameter of the engine is obtained.

And step S903, determining the adjusted power and the adjusted rotating speed as the adjusted operating parameters.

The adjusted operating parameters include the adjusted power and the adjusted rotation speed. In the actual use process, torque parameters can be added according to requirements, and the torque is used as a basic parameter of the engine and is related to power and rotating speed. The adjusted torque of the engine can be directly obtained according to the adjusted power and the adjusted rotating speed of the engine, and the charging of the power battery is realized by utilizing a charging strategy of the hybrid electric vehicle according to the torque value, the power value and the rotating speed value. Because the charging strategies of different types of hybrid electric vehicles are different, the strategy for charging the power battery by the engine by utilizing the adjusted power value, the rotation speed value and the torque value is also different. For example, in a hybrid vehicle in which the engine and the motor output driving force simultaneously, the engine is used not only to charge the power battery but also to drive the vehicle to run in the adjusted rotation speed range; for the extended range hybrid electric vehicle, the engine does not participate in the output of the driving force, and is only used for charging the power battery. Thus, the engine directly charges the power battery when determining the adjusted power and the adjusted speed of the engine. On the premise that the vibration generated by the engine does not exceed the vibration corresponding to the vibration data, the charging power of the engine to the power battery is as large as possible, and more electric quantity is charged into the power battery as much as possible.

The charging control method for the hybrid electric vehicle is described below with reference to a specific usage scenario, and is shown in fig. 10. In the embodiment, the hybrid electric vehicle is finally controlled to charge the power battery through the air volume adjusting value of the air conditioner. Firstly, acquiring an air volume adjusting value of an air conditioner in real time, acquiring the air volume adjusting value at the moment through an air volume control knob in an air conditioning system, and judging whether the air volume adjusting value is larger than a preset air volume adjusting threshold value or not after the air volume adjusting value is acquired. The judgment process can be immediately executed after the air volume is adjusted, namely, when the air volume of the air conditioner is adjusted by a user, the judgment can be carried out according to the adjusted air volume adjusting value and the preset air volume adjusting threshold value. If the air volume adjusting threshold value is larger than the preset air volume adjusting threshold value, comparing the air volume adjusting value with a corresponding relation curve containing the air volume adjusting value and the weighted value to obtain a rotating speed weighted value and a power weighted value of the engine; and if the air volume adjusting threshold value is not larger than the preset air volume adjusting threshold value, setting the rotating speed weight value and the power weight value to be 1.0. After a rotating speed weight value and a power weight value are obtained, multiplying the original rotating speed of the engine by the rotating speed weight value to obtain an adjusted rotating speed of the engine; meanwhile, multiplying the original power of the engine by the power weight value to obtain the adjusted power of the engine; and finally, charging the power battery by using the regulated engine speed and power.

In the process, the user can control the engine to charge the power battery by adjusting the air volume of the air conditioner, so that the vibration generated in the charging process is covered under the vibration generated by the air volume adjusting value as much as possible. If the hybrid electric vehicle is a range-extended hybrid electric vehicle, the engine is only used for charging the power battery as a range extender at the moment. When the range extender of the vehicle does not work, if the air volume of the air conditioner is adjusted by a user at the moment, the air conditioner generates vibration after being started, and the range extender is controlled to start working and charge the power battery at the moment. The vibration value that increases the produced vibration value of journey ware working process and be less than the vibration value that the air conditioner produced after starting, the user can not perceive the work that increases the journey ware after adjusting the regulation and control, has promoted charge efficiency on the basis that does not influence user's driving experience. And if the user adjusts the air volume of the air conditioner, the range extender is in a working state, the operating parameters of the range extender are controlled according to the vibration value generated after the air conditioner is adjusted, so that the charging efficiency of the power battery is improved on the premise of ensuring the fuel economy, and similarly, the vibration value generated in the working process of the range extender is lower than the vibration value generated after the air conditioner is started.

The above embodiments are based on the fact that the cab of the hybrid vehicle is in a closed state, and specifically are implemented when the window is closed, the sunroof is closed, and the trunk is closed. In practical situations, a user may open the door without extinguishing the fire, such as: special scenes such as payment and inspection are accepted, and at the moment, the charging process needs to be adjusted. Therefore, in some embodiments, after controlling the engine to charge the power battery of the hybrid vehicle, the method further comprises:

when the driver's cab of the hybrid electric vehicle is detected to be in a non-closed state, controlling the engine to stop charging a power battery of the hybrid electric vehicle; or when the time length for which the cab of the hybrid electric vehicle is detected to be in the non-closed state exceeds a preset time length threshold value, controlling the engine to stop charging the power battery of the hybrid electric vehicle.

According to the charging control method of the hybrid electric vehicle, the real-time vibration in the vehicle is associated with the charging process of the engine, so that the vibration generated when the engine charges the power battery is hidden in the real-time vibration corresponding to the vibration data, the NVH problem of the vehicle is relieved, and the driving experience of a user is improved; meanwhile, a scene of controlling the charging of the power battery by an engine in the hybrid electric vehicle is added, and the charging efficiency of the power battery is improved.

Corresponding to the above method embodiment, an embodiment of the present invention further provides a charging control system for a hybrid vehicle, a schematic structural diagram of which is shown in fig. 11, and the system includes:
