Detailed Description

The embodiment of the application provides an electric automobile control method, and the technical problem that in the prior art, when an electric automobile cannot supplement energy sources in time, energy consumption is high due to the fact that an automobile body is heavy is solved.

In order to solve the technical problems, the general idea of the embodiment of the application is as follows:

an electric vehicle control method, comprising: detecting the total residual capacity of N power batteries of the electric automobile, wherein N is a positive integer greater than 1; when the total remaining capacity is less than the preset capacity, determining whether a charging station exists within a preset distance; and when no charging station exists within the preset distance, determining a target power battery from the N power batteries, and controlling the target power battery to be separated from the electric vehicle at the preset moment.

According to the method, the moment of searching the charging station is determined according to the total residual capacity of the power batteries, when the charging station cannot be searched within the preset distance, the target power battery is selected from the power batteries, the target power battery is abandoned from the electric automobile at the preset moment, the weight of the automobile body is reduced, when the weight of the automobile body is reduced, the energy consumption of the electric automobile can be reduced, the same electric quantity can be driven farther, the purpose of prolonging the endurance mileage is achieved, the endurance mileage is prolonged, the probability of obtaining rescue can be improved, and the probability of the electric automobile being trapped in the field is reduced.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

The embodiment provides a control method of an electric vehicle as shown in fig. 1, and the method comprises the following steps:

step S11, detecting the total residual capacity of N power batteries of the electric automobile, wherein N is a positive integer greater than 1;

step S12, when the total remaining capacity is less than the preset capacity, determining whether there is a charging station within a preset distance;

and step S13, when no charging station exists within the preset distance, determining a target power battery from the N power batteries, and controlling the target power battery to be separated from the electric vehicle at the preset time at the preset moment so as to reduce the weight of the electric vehicle.

The number of power batteries on an electric vehicle is usually multiple (N in this embodiment). And detecting the total residual capacity at preset time intervals in the running state of the electric automobile. The preset time can be determined according to specific situations.

For example, when the total remaining power is greater than or equal to a preset power (the preset power may be 40%, and may be determined according to actual conditions), the preset time may be 10 minutes, that is, every 10 minutes, the detection is performed. When the total remaining capacity is less than the preset capacity, the preset time may be 3 minutes, i.e., every 3 minutes.

When the total remaining capacity is greater than or equal to the preset capacity, the N power batteries are sufficient in capacity. When the total remaining capacity is less than the preset capacity, it means that the capacity needs to be supplemented in time, and at this time, it can be determined whether there is a charging station within the preset distance. The preset distance is a distance which can be reached by the electric automobile by taking the current residual electric quantity as energy.

When a charging station exists within a preset distance, navigation can be started and the user can go to the charging station for energy supplement. When no charging station exists within the preset distance, in order to prolong the endurance mileage on the basis of the current residual capacity, the weight of the electric vehicle can be reduced to reduce energy consumption. The weight of the battery automobile is reduced by dropping the power battery.

Specifically, a target power battery is determined from the N power batteries, and the target power battery is controlled to fall off the electric vehicle at a preset moment. The number of the target power batteries can be one or more.

Determining a target power battery from the N power batteries, comprising:

step S21, detecting the sub remaining capacity of each power battery in the N power batteries;

step S22, determining estimated driving mileage corresponding to a plurality of power battery packs in the N power batteries according to the sub-residual capacity of each power battery;

and step S23, determining M power batteries from the N power batteries according to the estimated driving mileage corresponding to each power battery pack in the plurality of power battery packs and the received information of the shedding amount, and taking the M power batteries as target power batteries, wherein M is a positive integer smaller than N.

The sub-remaining capacity of each of the N power batteries is detected, different power batteries are combined (it should be noted that the combination in this embodiment may also be formed by a single power battery), and different estimated driving mileage may be obtained.

For example, when the number of the power batteries is 3, the 3 power batteries are respectively referred to as a 1# power battery, a 2# power battery and a 3# power battery, the sub-residual electric quantities are respectively 40%, 30% and 38%, and the corresponding driving ranges are respectively 60Km, 48Km and 56Km, then the following various combinations and the estimated driving distances thereof can be obtained:

1# power battery: 60 Km;

2# power battery: 48 Km;

3# power battery: 56 Km;

1# power battery and 2# power battery: 108Km (60Km +48 Km);

1# power battery and 3# power battery: 116Km (60Km +56 Km);

2# power battery and 3# power battery: 104Km (48Km +56 Km).

The M power batteries needing to be dropped can be determined as target power batteries according to different estimated driving mileage, and the estimated driving mileage can be displayed on an interface for a driver to select the M power batteries needing to be dropped. M power batteries are selected from the N power batteries as target power batteries, and when N is 3, then M may be 1 or 2.

The above mode mainly determines the target power battery needing to be dropped according to the estimated driving mileage, and also can determine the target power battery needing to be dropped according to the installation position of the power battery on the electric automobile, and the method specifically comprises the following steps:

step S31, determining the performance requirement of the electric automobile passing through the current road condition according to the road condition characteristics of the electric automobile;

and step S32, determining M power batteries from the N power batteries according to the performance requirements and the distribution positions of the N power batteries on the electric automobile.

The road condition characteristics may be wading road section characteristics, climbing road section characteristics, descending road section characteristics, relatively flat road section characteristics, and the like. The performance requirements of electric vehicles are different for different road conditions. For example, the characteristics of a wading road section, a climbing road section and a descending road section need to improve the longitudinal passing capacity and the off-road capacity of the whole vehicle when the whole vehicle leaves a slope section and approaches the slope section, and the characteristics of a smoother road section need to improve the operation stability of the whole vehicle.

Therefore, the performance requirements of the vehicle can be determined according to the road condition characteristics, and the weight adjustment of each position (mainly referring to the front, middle and rear positions of the vehicle body) of the vehicle body can be determined according to the performance requirements, namely, the target power battery needing to be dropped is determined according to the distribution position of the power batteries on the electric vehicle.

As shown in fig. 2, a schematic diagram of a mode after discarding different power batteries for 3 power batteries is shown, where a mode 1 is a mode of discarding a # 2 power battery and a # 3 power battery and retaining a # 1 power battery; mode 2 is a mode of abandoning the 1# power battery and the 3# power battery and reserving the 2# power battery; the mode 3 is a mode of abandoning the 1# power battery and the 2# power battery and reserving the 3# power battery; mode 4 is a mode of abandoning the 3# power battery and reserving the 1# power battery and the 2# power battery; mode 5 is a mode of abandoning the No. 2 power battery and reserving the No. 1 power battery and the No. 3 power battery; mode 6 is a mode in which the # 1 power battery is discarded and the # 2 power battery and the # 3 power battery are reserved.

Two power batteries are reserved in the mode 5, so that the axle load is balanced, and the operation stability of the whole vehicle is more facilitated; modes 4 and 6 respectively improve the longitudinal passing capacity and the off-road capacity of the vehicle when the vehicle leaves or approaches to the rough road condition. The mode 1 and the mode 3 can greatly improve the longitudinal passing capacity and the cross-country capacity of the whole vehicle when the whole vehicle leaves and approaches to the severe working condition; mode 2 is more favorable to the whole car steering stability.

When the longitudinal passing capacity and the off-road capacity of the whole vehicle leaving the slope section and approaching the slope section need to be improved, the mode can be selected from the modes 1, 3, 4 and 6, and when the steering stability of the whole vehicle needs to be improved, the mode can be selected from the modes 2 and 5.

In summary, in this embodiment, the time of searching for the charging station is determined according to the total remaining capacity of the power batteries, when the charging station cannot be searched within the preset distance, the target power battery is selected from the plurality of power batteries, and the target power battery is discarded from the electric vehicle at the preset time, so as to reduce the weight of the vehicle body. When the target power battery is selected, the weight configuration of the whole electric automobile can be changed by combining the performance requirements corresponding to the driving road condition of the electric automobile, so that the efficiency of the electric automobile passing through the current road condition is higher.

The electric automobile that provides in this embodiment can drive in cross-country environment, in cross-country road conditions, ground unevenness, and power battery installs in electric automobile bottom position, takes place to collide with easily, for promotion electric automobile's cross-country performance, also for protection power battery itself, can give up the power battery priority of touchhing down easily.

Specifically, the method for determining the target power battery from the N power batteries comprises the following steps:

step S41, detecting the collision frequency of each power battery of the N power batteries;

and step S42, taking the power battery with the collision frequency exceeding the preset frequency as the target power battery.

And detecting the collision frequency of each power battery in the N power batteries, and taking the power battery exceeding the preset frequency as a target power battery which can be separated.

As shown in fig. 3, the locations where collision frequently occurs are marked, it can be seen that 1# power battery is easy to collide, then 1# power battery can be abandoned, after 1# power battery is abandoned, 2# power battery is easy to collide, then 2# power battery is abandoned, after abandoning, the installation positions of 1# power battery and 2# power battery are vacant, so that the corresponding space on the collision locations is enlarged, and the vehicle bottom is not easy to collide.

After the target power battery is determined from the N power batteries, before the control target power battery is disengaged from the electric vehicle at the preset time, the method further comprises:

step S51, controlling a target power battery to supply power for the electric automobile;

and step S52, when the residual capacity of the target power battery is lower than a preset threshold, controlling the target power battery to be disengaged from the electric automobile at a preset moment.

After the target power battery is determined, the target power battery also has residual electric quantity, the residual electric quantity in the target power battery needs to be exhausted (the exhausted residual electric quantity of the target power battery is lower than a preset threshold value, and the preset threshold value can be set according to specific conditions), and then the target power battery is detached, so that all the residual electric quantity is fully utilized, and the driving mileage of the electric automobile is prolonged.

After the control target power battery is disconnected from the electric vehicle at the preset moment, the method further comprises the following steps:

and step S61, acquiring the target position of the target power battery falling off, and storing the target position.

The power battery is high in manufacturing cost, and the position where the target power battery falls off can be recorded in order to recover the power battery, so that later-period itinerant operation is facilitated. A GPS tracker may also be installed on the power battery to determine the location of the target power battery.

The embodiment can be applied to the electric automobile running on off-road conditions, and when the residual electric quantity of the power batteries is insufficient and the charging and replacing stations cannot be searched, the power batteries with different quantities can be controlled to fall off, so that the weight of the whole automobile is reduced and the driving range is increased; meanwhile, according to the driving road condition and the installation position of the power battery, the power battery at the corresponding position is appointed to fall off, so that the controllability, the geometric trafficability characteristic and the off-road characteristic of the whole vehicle are considered.

In addition, the power battery is used as a component assembly with the minimum ground clearance of the vehicle, and when the vehicle faces bad road conditions (for example, the vehicle climbs over an extreme obstacle convex hull, as shown in fig. 4), the vehicle is very easy to support bottom collision, so that the battery is damaged and leaked, and safety crisis is brought. Under the condition that special requirements are required for trafficability, the power batteries at different positions in the power batteries can be controlled to fall off through strategies, the longitudinal trafficability and the off-road performance of the vehicle are improved, and the escaping is realized.

As shown in fig. 5, it is a flow chart of battery dropping during the driving process of a certain electric vehicle with 3 power batteries (the total number of power batteries is 3, as shown in fig. 2).

When the battery SOC is less than or equal to 30%, the remaining SOC (State Of Charge, which refers to the State Of Charge Of the battery, also called the remaining capacity, which represents the ratio Of the remaining dischargeable capacity to the capacity in its fully charged State after the battery has been used for a certain period Of time or left unused for a long time, and is expressed as a percentage).

And searching for a battery replacement/charging station nearby, and if the battery replacement/charging station exists, navigating to the place. If not, judging whether the power batteries need to be dropped emergently, if not, keeping running, and if so, displaying estimated values of the driving range of the power batteries with different numbers of drops.

If the drop-out 1 power battery is selected, it is determined whether the passing performance or the handling performance is preferentially ensured, and if the drop-out 1 power battery is selected, the mode 5 (shown in fig. 2) is selected, and if the drop-out 1 power battery is selected, the mode 6 (shown in fig. 2) is selected, and if the drop-out 1 power battery is both selected, the mode 4 (shown in fig. 2) is selected.

If 2 detached power batteries are selected, whether passing or handling is preferentially ensured is determined, if the former is the case, mode 1 (shown in fig. 2) is selected, if the latter is the case, mode 2 (shown in fig. 2) is selected, and if both are compatible, mode 3 (shown in fig. 2) is selected.

After the power battery needing to be dropped is determined, the electric quantity of the power battery needing to be dropped is preferentially used through the SOC control measurement of the battery, the electric quantity change is monitored constantly, the power battery is dropped after the electric quantity loss of the power battery needing to be dropped is completed, and then the repeated utilization rate of the power battery can be improved through the GPS itineration of the power battery.
