When the temperature of the environment where the vehicle is located is low, a current appropriate heating mode can be recommended to a user through a multimedia device of the vehicle according to the current remaining capacity of the battery of the finished vehicle (for example, the recommended heating mode can be displayed through a touch display screen of the multimedia device, or the recommended heating mode can be broadcasted through a multimedia voice broadcast function, and a specific recommendation mode can refer to related technologies, which are not limited by the disclosure); or, by acquiring the current navigation travel data, determining whether the surplus electric quantity exists or not under the condition that the current residual electric quantity of the vehicle battery meets the travel requirement according to the navigation travel data, recommending an electric heating mode to a user if the surplus electric quantity exists, and recommending a fuel heating mode to the user if the surplus electric quantity does not exist. The user can set the current heating mode according to the recommendation of the multimedia device.

When the vehicle needs to be heated by a battery while performing air-conditioning heating, the fuel heater 102 can be controlled to be started, the PTC water heater 1021 is closed, the warm air water pump 1022 is operated, the warm air core 1023 is started, the first pipe orifice and the second pipe orifice of the electric four-way valve 1024 are communicated, the third pipe orifice and the fourth pipe orifice are communicated, the circulating water flows through the battery pack 1025 and the battery heating water pump 1026 after flowing through the first pipe orifice and the second pipe orifice of the electric four-way valve 1024, then passes through a third pipe orifice and a fourth pipe orifice of the electric four-way valve 1024, then passes through the warm air core 1023, and then returns to the fuel heater 102 to form another heat circulation loop, so that the circulating water heated by the fuel heater 102 flows through the warm air core 1023 to supply heat for air-conditioning heating of the vehicle, meanwhile, circulating water heated by the fuel heater 102 flows through the battery pack 1025, so that the function of heating the battery is realized.

Under the condition that only the battery needs to be heated and the heating function of the vehicle air conditioner is not started, the fuel oil heater 102 can be controlled to be started, the PTC water heater 1021 is closed, the warm air core 1023 is closed, the warm air water pump 1022 runs, the first pipe orifice and the second pipe orifice of the electric four-way valve 1024 are communicated, the third pipe orifice and the fourth pipe orifice are communicated, circulating water flows through the battery pack 1025 and the battery heating water pump 1026 after flowing through the first pipe orifice and the second pipe orifice of the electric four-way valve 1024, then passes through a third pipe orifice and a fourth pipe orifice of the electric four-way valve 1024, then flows through the warm air core 1023, returning to the fuel heater 102, a corresponding heating circuit is formed, at this time, since the warm air core 1023 is closed, therefore, the heated circulating water can not radiate heat at the hot air core 1023, namely, the air conditioning and heating functions are switched off, therefore, the heated circulating water only radiates heat at the battery pack 1025, and only the battery is heated.

It should be noted that, in the fuel heating mode, since the heat source is provided by the fuel burned by the fuel heater, the heat source may generate heat containing carbon monoxide, carbon dioxide, hydrocarbons, sulfides (SO and SO)₂) Nitrogen oxides (e.g. NO and NO)₂) And exhaust gas of solid particulate matter and the like, wherein the generation process of the exhaust gas can be seen in fig. 1b, and fig. 1b is an oil circuit diagram of a vehicle heating system shown in an exemplary embodiment of the disclosure; as shown in fig. 1b, fuel in the fuel heater 102 is pumped into the fuel heater 102 from a fuel tank 1027 by a fuel pump 1028, air enters the fuel heater 102 from an intake muffler 1029 through an intake pipe, the fuel is ignited under the combustion of oxygen in the air in the fuel heater 102, so as to heat circulating water flowing through the fuel heater 102 (a circulating water path diagram can be seen in fig. 1 a), heat provided by fuel combustion is brought to a battery pack by the circulating water to heat a battery, and/or heat provided by fuel combustion is brought to a warm air core by the circulating water to provide heat for vehicle air-conditioning heating, and exhaust gas after combustion in the fuel heater 102 flows through an exhaust muffler 10210 and is exhausted out of a vehicle through an exhaust gas exhaust pipe.

When the user sets the current heating mode to the electric heating mode, the vehicle heating system operation process may include the following cases:

under the condition that a user starts the vehicle air-conditioning heating function, the PTC water heater 1021 is controlled to be started, the fuel oil heater 102 is controlled to be closed, the warm air water pump 1022 runs, and circulating water flows through the warm air core 1023 after flowing through the first pipe orifice and the third pipe orifice in the electric four-way valve 1024 and then returns to the PTC water heater 1021, so that a heat circulating loop is formed, and the vehicle air-conditioning heating function is realized by heat dissipation of the warm air core 1023.

When a user starts a vehicle air-conditioning heating function and needs to heat a battery, the PTC water heater 1021 is controlled to be started, the fuel oil heater 102 is turned off, the warm air water pump 1022 runs, the first pipe orifice and the second pipe orifice of the electric four-way valve 1024 are connected, the third pipe orifice and the fourth pipe orifice are connected, circulating water flows through the battery pack 1025 and the battery heating water pump 1026 after flowing through the first pipe orifice and the second pipe orifice of the electric four-way valve 1024, then flows through the warm air core 1023 after flowing through the third pipe orifice and the fourth pipe orifice of the electric four-way valve 1024, and then returns to the PTC water heater 1021 to form another heat circulation loop, so that the circulating water heated by the PTC water heater 1021 flows through the warm air core 1023 and the battery pack 1025, and the vehicle air-conditioning heating and battery heating functions are achieved.

Under the condition that only the battery needs to be heated and the heating function of the vehicle air conditioner is not started, the PTC water heater 1021 can be controlled to be started, the fuel oil heater 102 is turned off, the warm air water pump 1022 is operated, the warm air core 1023 is turned off, the first pipe orifice and the second pipe orifice of the electric four-way valve 1024 are communicated, the third pipe orifice and the fourth pipe orifice are communicated, circulating water flows through the battery pack 1025 and the battery heating water pump 1026 after flowing through the first pipe orifice and the second pipe orifice of the electric four-way valve 1024, then passes through a third pipe orifice and a fourth pipe orifice of the electric four-way valve 1024, then flows through the warm air core 1023, returning to the fuel heater 102, a corresponding heating circuit is formed, at this time, since the warm air core 1023 is closed, therefore, the heated circulating water can not radiate heat at the hot air core 1023, namely, the air conditioning and heating functions are switched off, therefore, the heated circulating water only radiates at the battery pack 1025, and only the battery is heated.

Thus, under the condition that the current heating mode is set to be the fuel heating mode according to the recommendation of the multimedia device by the user, the fuel heater 102 burns fuel to provide heat for the vehicle heating system, and under the condition that the current heating mode is set to be the electric heating mode according to the recommendation of the multimedia device by the user, the PTC water heater 1021 provides heat for the vehicle heating system, so that the heat supply requirement of the vehicle heating system can be guaranteed under the condition that the cruising range of the vehicle is guaranteed, and the riding experience of the vehicle user can be improved.

FIG. 2 is a block diagram of an auxiliary control system for an air conditioner according to an exemplary embodiment of the present disclosure; referring to fig. 2, the system includes: a controller 101, and a fuel oil heater 102 and a parameter acquisition component 103 which are respectively connected with the controller 101,

the fuel heater 102 is used for providing heat for the vehicle by means of fuel heating when the heating mode of the vehicle is a fuel heating mode;

the fuel heater 102 may provide heat for vehicle air conditioning heating and/or vehicle battery heating, among other things.

The parameter acquisition component 103 is used for acquiring air-conditioning auxiliary control parameters of the vehicle, wherein the air-conditioning auxiliary control parameters comprise gas detection parameters; and/or, a current operating state parameter of the vehicle;

the controller 101 is configured to execute an air conditioner waste gas auxiliary treatment strategy corresponding to the air conditioner auxiliary control parameter according to the air conditioner auxiliary control parameter acquired by the parameter acquisition component.

The gas detection parameters may include the gas component content, the gas concentration, and the like, and the current operating state parameters may include the current driving speed of the vehicle, the environmental information of the vehicle, and the indication information for indicating whether the vehicle is in an air-conditioning heating state (i.e., whether the external circulation air inlet of the vehicle is open), and the like.

The air conditioner waste gas auxiliary treatment strategy corresponding to the execution of the air conditioner auxiliary control parameter in the present disclosure will be described below with respect to different air conditioner auxiliary control parameters.

In this embodiment, in the case that the air-conditioning auxiliary control parameter includes the current operating state parameter of the vehicle, the air-conditioning exhaust gas auxiliary treatment strategy corresponding to the air-conditioning auxiliary control parameter may be implemented in the following two manners:

the first method is as follows: when the current running state of the vehicle is an idling state; and/or, under the condition that the vehicle is determined to be in a closed environment, the heating mode of the vehicle can be switched to the electric heating mode, and as the exhaust gas generated by the vehicle in the heating mode is avoided in the electric heating mode, the problem of poor riding experience caused by the fact that the exhaust gas cannot be dispersed into the vehicle in time is solved.

Illustratively, as shown in fig. 3, fig. 3 is a block diagram of an air conditioner auxiliary control system according to the embodiment shown in fig. 2; the system further comprises: an electric heater 104 connected to the controller 101, wherein the parameter collecting component 103 comprises a speed collecting device 1031 and a driving environment judging device 1032 in case that the air-conditioning auxiliary control parameter comprises a current running state parameter of the vehicle;

the electric heater 104 is used for providing heat to the vehicle by means of electric heating when the heating mode of the vehicle is an electric heating mode;

the speed collecting device 1031 is used for collecting the current running speed of the vehicle;

the driving environment judgment device 1032 is used for judging the current environment of the vehicle;

the controller 101 is configured to determine that a current operation state of the vehicle is an idle state according to the driving speed; and/or switching the heating mode of the vehicle to the electric heating mode in case that the vehicle is determined to be in the closed environment.

The electric heater 104 may be a PTC water heater, the speed collecting device 1031 may be a speed sensor, the driving environment determining device 1032 may be connected to an environment monitoring device of the vehicle, and the environment detecting device may include a vehicle body camera, a radar, a GPS (Global Positioning System) Positioning device, an on-vehicle monitoring device, a driving recording device, and the like, which is not limited in this disclosure.

In one possible implementation manner, the current running speed of the vehicle may be collected through a speed sensor, and in the case that the running speed of the vehicle in a preset time period is always less than or equal to a preset speed threshold value, it is determined that the vehicle is in an idle state.

In another possible implementation manner, whether the vehicle is in a closed environment may be determined by environment information around the vehicle acquired by the environment monitoring device, and one manner of determining whether the vehicle is in the closed environment is to determine whether obstacles exist on the left side, the right side and the top of the vehicle by using a camera, a radar, an on-board monitoring device or a driving recording device, and when it is determined that obstacles exist on the left side, the right side and the top of the vehicle, it is determined that the current driving environment of the vehicle belongs to the closed environment. The other mode is that the current position of the vehicle is determined through a GPS positioning device, whether the position belongs to a cave, a garage or the position of other non-open areas is determined, and when the current position of the vehicle is determined to belong to the cave, the garage or the position of other non-open areas, the current driving environment of the vehicle is determined to belong to the closed environment.

In the second mode, when the vehicle is in an air-conditioning heating state (namely, the external circulation air inlet of the vehicle is opened), the air is blown to the air outlet through the air blowing device arranged at the air outlet of the fuel oil heater, so that the exhaust gas discharged from the air outlet is blown to the direction far away from the external circulation air inlet. Like this, because this extrinsic cycle air intake is the inside device of taking a breath with the outside of vehicle, consequently, when the extrinsic cycle air intake of this vehicle was in the open mode, this blast apparatus of control blown this waste gas to the direction of keeping away from this extrinsic cycle air intake, can effectively avoid inside this waste gas gets into the vehicle to avoid causing the phenomenon that bad vehicle was ridden and is driven and experience.

Illustratively, still taking the above-mentioned fig. 3 as an example, the system further includes: an air blowing device 105 arranged at the air outlet of the fuel oil heater, wherein the air blowing device 105 is connected with the controller 101;

the controller 101 is configured to control the blowing device 105 to blow air towards the air outlet when the current operating state of the vehicle is that the external circulation air inlet of the vehicle is open, so as to blow the exhaust gas discharged from the air outlet towards a direction away from the external circulation air inlet.

The blowing device 105 is a device for accelerating air flow, and may be an electronic fan, for example.

It should be noted that, the external circulation air inlet can be opened or closed by setting a vehicle gas circulation mode, and the external circulation air inlet is in a closed state when the vehicle is in a gas internal circulation state; when the vehicle is in the gas internal and external circulation state, the external circulation air inlet is in an open state. The specific structure of the external circulation air inlet can refer to the structure in the related art, and the detailed description of the disclosure is omitted here.

In the case that the air-conditioning auxiliary control parameter includes a gas detection parameter of the vehicle, the air-conditioning waste gas auxiliary treatment strategy corresponding to the air-conditioning auxiliary control parameter may be implemented by the following two implementation manners:

in the first mode, whether the fuel burnt by the fuel heater is burnt sufficiently is determined by detecting the component content of the exhaust gas discharged from the gas outlet, and under the condition that the fuel burnt by the fuel heater is not burnt sufficiently, the air inflow amount and/or the oil inflow amount of the fuel heater are/is adjusted to enable the fuel burnt by the fuel heater to be burnt sufficiently. Like this, through making the fuel abundant burning of fuel heater burning to effectively improve the utilization ratio of fuel, reach resources are saved, reduce exhaust emission's effect, and then solved waste gas and in time scattered and get into inside the vehicle, cause the problem that bad ride and drive the experience.

Illustratively, as shown in fig. 4, fig. 4 is a block diagram of another air conditioner auxiliary control system according to the embodiment shown in fig. 2; in the case where the air conditioner auxiliary control parameter includes the gas detection parameter, the parameter acquisition assembly 103 includes a first gas detection sensor 1033 disposed at the fuel heater gas outlet, the first gas detection sensor 1033 is connected to the controller 101,

the first gas detection sensor 1033 for detecting a component content of the exhaust gas discharged from the gas outlet;

the controller 101 is used for determining whether the fuel burnt by the fuel heater is sufficiently burnt according to the component content; and under the condition that the fuel burnt by the fuel heater is determined to be insufficiently burnt, adjusting the air intake quantity and/or the oil intake quantity of the fuel heater so as to ensure that the fuel burnt by the fuel heater is sufficiently burnt.

Wherein the component content of the waste gas is a gas detection parameter,

in the present embodiment, in the case where the detected content of the component of the exhaust gas is greater than or equal to the preset content threshold value, it is determined that the fuel is not sufficiently combusted in the fuel heater 102, and in the case where the detected content of the component of the exhaust gas is less than the preset content threshold value, it is determined that the fuel is sufficiently combusted in the fuel heater 102.

For example, taking the example that the exhaust gas includes CO (carbon monoxide) and HC (hydrocarbon) as an example, the first gas detection sensor 1031 detects the contents of CO (carbon monoxide) and HC (hydrocarbon) respectively, determines that the fuel in the fuel heater 102 is not sufficiently combusted in the case where the content of any of the CO and HC compounds is greater than or equal to the preset content threshold, and determines that the fuel in the fuel heater 102 is sufficiently combusted in the case where the content of both of the CO and HC compounds is less than the preset content threshold.

In the case of adjusting the air intake of the fuel heater 102 to make the fuel in the fuel heater 102 burn sufficiently, the air flow speed can be increased by increasing the speed of the fan inside the fuel heater 102, so as to increase the air intake of the fuel heater, so that the ratio of the air intake to the fuel entering the fuel heater is increased until the component content of the exhaust gas is less than the preset content threshold. Thereby enabling the fuel burned by the fuel heater to be more fully burned.

Under the condition that the fuel in the fuel heater 102 is fully combusted by adjusting the fuel inlet amount of the fuel heater 102, the fuel pumping frequency of the fuel pump can be reduced by reducing the voltage of the fuel pump, so that the fuel inlet amount entering the fuel heater 102 per unit time is reduced, the ratio of the air inlet amount to the fuel entering the fuel heater is increased until the component content of the waste gas is less than the preset content threshold value, and the fuel entering the fuel heater is fully combusted.

It should be noted that, in this embodiment, the air intake amount and the oil intake amount of the fuel heater 102 may also be adjusted at the same time, that is, the voltage of the oil pump may be reduced while the rotation speed of the fan inside the fuel heater 102 is increased, so that the oil intake amount entering the fuel heater 102 per unit time is reduced while the air intake amount is increased, so that the ratio of the air intake amount to the fuel entering the fuel heater is rapidly increased until the component content of the exhaust gas is less than the preset content threshold, so that the fuel entering the fuel heater is combusted more sufficiently. Like this, adjust the air input simultaneously and advance the proportion of oil mass increase air input and oil mass, can effectively improve the regulation efficiency of oil gas proportion to can reduce exhaust emission rapidly, avoid getting into the vehicle inside because of waste gas can't in time scatter, cause the problem that the not good ride drives the experience.

In the second mode, the concentration of the specified gas in the passenger compartment of the vehicle is detected, and in the case that the concentration of the specified gas exceeds a preset concentration threshold value, one or more of the following air-conditioning waste gas auxiliary treatment strategies are executed:

setting the heating mode of the vehicle as an electric heating mode;

opening the air purification device disposed in the passenger compartment;

and closing the external circulation air inlet under the condition that the external circulation air inlet of the vehicle is opened.

Like this, in the passenger cabin appointed gaseous concentration be greater than or equal to predetermine under the condition of concentration threshold value, in time carry out exhaust-gas treatment effectively, the peculiar smell appears in the effectual passenger cabin of avoiding to can effectively promote the ride of vehicle and drive experience.

Illustratively, still taking the above-mentioned fig. 4 as an example, the system further includes: an air cleaning device 106 disposed in a passenger compartment of the vehicle, the air cleaning device 106 being connected to the controller 101, in case the air-conditioning auxiliary control parameter includes the gas detection parameter, the parameter acquisition component 103 includes a second gas detection sensor 1034 disposed in the passenger compartment, the second gas detection sensor 1034 being connected to the controller 101,

the second gas detection sensor 1034 for detecting the concentration of the specified gas in the passenger compartment;

the controller 101 is configured to, if the concentration is greater than or equal to a preset concentration threshold, execute one or more of the following air conditioner exhaust gas auxiliary treatment strategies:

setting the heating mode of the vehicle as an electric heating mode;

opening the air cleaning device 106 disposed in the passenger compartment;

and closing the external circulation air inlet under the condition that the external circulation air inlet of the vehicle is opened.

The air purification device 106 is used to filter out the specified gases in the air in the passenger compartment of the vehicle, which may include carbon monoxide, carbon dioxide, sulfides (SO and SO2), nitrogen oxides (e.g., NO and NO) in the exhaust gas₂) And harmful gases such as solid particles.

In this embodiment, the specified gas may be filtered out by the air purification device, or the air circulation mode of the vehicle may be changed from the internal and external circulation mode to the internal circulation mode to close the external circulation air inlet when the external circulation air inlet of the vehicle is opened; the heating mode can also be switched from the fuel heating mode to the electric heating mode to avoid the continuous production of harmful gases.

In summary, the smell of the exhaust gas in the vehicle can be effectively removed in time by any one of the above manners, and the riding experience of the vehicle user is improved.

It should be noted that, considering that in the actual wiring process of the air-conditioning auxiliary control system, that is, in the process of connecting the fuel heater 102, the electric heater 104, the speed collection device 1031, the driving environment determination device 1032, the first gas detection sensor 1033, the second gas detection sensor 1034, the air purification device 106, and the blower device 105 to the controller 101, when the controller 101 is provided in the front compartment of the vehicle, the second gas detection sensor 1034, the air purification device 106, and the oil pump 1028 provided in the rear compartment of the vehicle are required to be connected to the controller 101 through the front and rear compartment baffle plates, if the controller 101 is provided in the rear compartment, the fuel heater 102, the electric heater 104, the first gas detection sensor 1033, the speed collection device 1031, the driving environment determination device 1032, and this blast apparatus 105 need pass the baffle of front deck and rear deck and be connected this controller 101, will increase the wiring degree of difficulty like this, also can leave a plurality of through wires holes on the baffle of front deck and rear deck, is unfavorable for reducing the equipment degree of difficulty of vehicle. In order to overcome the problem of high cross-region wiring difficulty, the present disclosure provides the following embodiments:

In this step, when the air-conditioning auxiliary control parameter includes the current operating state parameter of the vehicle, the air-conditioning waste gas auxiliary treatment strategy corresponding to the air-conditioning auxiliary control parameter may be executed in the following two implementation manners:

In the second mode, when the vehicle is in an air-conditioning heating state (namely, the external circulation air inlet of the vehicle is opened), the air is blown to the air outlet through the air blowing device arranged at the air outlet of the fuel oil heater, so that the exhaust gas discharged from the air outlet is blown to the direction far away from the external circulation air inlet. Like this, when the extrinsic cycle air intake of this vehicle is in the open mode, then this blast apparatus of control blows off this waste gas, can effectively avoid this waste gas to get into vehicle inside to can avoid causing the phenomenon that bad vehicle takes advantage of and drives experience.

In addition, in this step, when the air-conditioning auxiliary control parameter includes a gas detection parameter of the vehicle, the air-conditioning exhaust gas auxiliary treatment strategy corresponding to the air-conditioning auxiliary control parameter may be executed in the following two implementation manners:
