Description

Technical Field

[0001] The present application relates to the field of vehicle air conditioning control, and in particular to a vehicle air conditioning control method, device, equipment and medium. Background Art

[0002] With the rise of new energy vehicles, related industries of new energy vehicles are booming. As for air conditioning and heating in new energy vehicles, some new energy vehicles use PTC (Positive Temperature Coefficient) to achieve air conditioning and heating. The working principle is to energize the PTC ceramic semiconductor material through a high-voltage power battery, use the Joule effect to convert electrical energy into thermal energy, and heat the coolant flowing through the PTC module. The heated coolant is driven into the heater core through a heater water pump, and then the blower sends the hot air into the car.

[0003] However, there is air in the heater core and the coolant circuit. After the production of new energy vehicles, it is difficult to completely expel the air in the system by using the vacuum filling method. In addition, the natural filling method is used to fill the coolant during vehicle after-sales maintenance, which often leaves a large amount of air in the system. If there is air in the coolant circuit or heater core of the air conditioning and heating system, then during the start-up of the air conditioning and heating system, the heater water pump starts at a higher speed. Due to the retained air, the coolant circulates rapidly, resulting in obvious water impact sound, causing a poor user experience.

The method proposed in this application effectively reduces the water flow impact sound generated by the high-speed rotation of the heater pump during the heating startup of the vehicle air conditioner, thereby improving the user experience.

[0078] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0079] In the drawings, the sizes of components, layer thicknesses, or regions may be exaggerated for clarity. Therefore, any implementation of the present disclosure is not necessarily limited to the dimensions shown in the drawings, and the shapes and sizes of components in the drawings do not reflect true proportions. Furthermore, the drawings schematically illustrate idealized examples, and any implementation of the present disclosure is not limited to the shapes or values ​​shown in the drawings.

[0080] In the related art, after the on-board air conditioner of a new energy vehicle is produced, the excess gas in the coolant circuit is often discharged through the vacuum filling method. Although this method can discharge a large amount of excess gas in the coolant circuit, some gas will still remain. When the on-board air conditioner is started, the heater water pump rotates at high speed, driving the coolant in the coolant circuit and the residual gas to flow together, thereby generating a noticeable sound of running water, which can cause trouble to users and affect their experience. In addition, after a new energy vehicle has been used for a period of time, the coolant circuit of the on-board air conditioner is often refilled with coolant using the natural filling method during after-sales maintenance. At this time, more air will remain in the coolant circuit than when it left the factory, causing the on-board air conditioner to produce more noticeable noise during the heating startup process, further affecting the user's driving experience.

[0081] Therefore, in order to at least partially solve one or more of the above-mentioned problems and other potential problems, an embodiment of the present application proposes a vehicle air-conditioning control method, which can not only effectively reduce the noise generated by the vehicle air-conditioning during the heating startup process, but also avoid adverse effects on other modules in the vehicle air-conditioning.

[0082] Please refer to the Figure 1 , Figure 1 This is a flow chart of a vehicle air conditioning control method proposed in one embodiment of the present application. Figure 1 As shown, the method may include steps S101 to S103:

[0083] Step S101: in response to a user's air conditioning and heating demand, starting a heater water pump of a current vehicle and controlling the heater water pump of the current vehicle to operate at a first speed;

[0084] Step S102: After the heater water pump of the current vehicle is controlled to operate at a first speed for a first duration, adjusting the speed of the heater water pump of the current vehicle with a target speed as a target;

[0085] Step S103: After the rotation speed of the heater water pump of the current vehicle reaches the target rotation speed, the heater water pump of the current vehicle is maintained to operate at the target rotation speed.

[0086] In the embodiment of the present application, the main process of the control method for the vehicle air conditioner is to start the heater water pump of the current vehicle and maintain it at a first speed for a first period of time according to the user's air conditioning and heating needs after the vehicle air conditioner is turned on. The purpose is to discharge the gas in the coolant circuit through the operation of the heater water pump, thereby reducing the noise emitted by the coolant circuit. After the first period of time, the speed of the heater water pump is increased to the target speed and maintained at the target speed. For the sake of convenience, this application provides a schematic diagram of the coolant circuit of the vehicle air conditioner, as shown in FIG. Figure 2 As shown, Figure 2 This is a schematic diagram of a coolant circuit for a vehicle air conditioner proposed in one embodiment of the present application, wherein passages 1 and 3 of the three-way valve form a coolant circuit for heating the vehicle air conditioner. The coolant in the coolant circuit is driven by a warm air water pump, and passes through the heater, i.e., the heating module, to heat the coolant. The coolant then flows through the warm air core, and the heated coolant heats the warm air core. The air blown by the blower passes through the warm air core and is blown into the vehicle, thereby achieving air conditioning and heating. The expansion kettle is used to replenish the coolant circuit through the refill tube, and passage 2 of the three-way valve is used to heat the power battery of the new energy vehicle. The heat exchange of the coolant is achieved between the high-temperature side and the low-temperature side of the figure, and the heated coolant is then driven by the water pump on the left side of the figure to continue heating the power battery. No further details will be given here.

[0087] In this application, if Figure 2 As shown, since the exhaust pipe in the coolant circuit can exhaust the gas in the coolant circuit, during the first time period proposed in this application, the heater water pump is first operated at a first speed to discharge a portion of the air remaining in the coolant circuit through the exhaust pipe, and then the speed of the heater water pump is slowly increased to the target speed, thereby reducing the noise generated in the coolant circuit during the startup process, and discharging the air in the coolant circuit before entering the normal working state of the vehicle air conditioner, avoiding the situation where the heater water pump is directly started at the target speed when starting the vehicle air conditioner, causing the coolant to flow at a large flow rate, thereby generating water flow impact sound.

[0088] Step S101: in response to a user's air conditioning and heating demand, starting a heater water pump of a current vehicle and controlling the heater water pump of the current vehicle to operate at a first speed.

[0089] In the embodiment of the present application, regarding the user's heating needs, specifically, after the user proposes the need to use the vehicle air conditioner for heating, the current environmental information of the vehicle will be obtained first, including ambient temperature, interior temperature, light intensity, vehicle speed and other information. Among them, the ambient temperature and interior temperature are used as a reference for whether the current environment meets the heating needs proposed by the user. When it does not meet the air-conditioning and heating needs proposed by the user, a corresponding air-conditioning and heating strategy is formulated according to the environmental conditions such as the light intensity and vehicle speed of the vehicle, including the coolant flow and coolant temperature required for heating, as well as the blower wind speed, etc., so that the target speed required for the heater water pump can be determined according to the coolant flow.

[0090] At the same time, in order to avoid the coolant loop containing air from flowing rapidly and producing obvious water flow noise when starting due to the target speed being too high, the heater water pump of the current vehicle can be controlled to run at the first speed after starting the heater water pump of the current vehicle.

[0091] Step S102: After the heater water pump of the current vehicle is controlled to operate at a first speed for a first duration, the speed of the heater water pump of the current vehicle is adjusted with the target speed as the target.

[0092] In an embodiment of the present application, after the heater water pump of the current vehicle has been running at a first speed for a first period of time, it is considered that most of the air remaining in the coolant circuit has been discharged through the exhaust pipe, so the speed of the heater water pump can be adjusted from the first speed to the target speed.

[0093] Generally speaking, the target speed is generally greater than the set first speed, but in an optional embodiment, there is also a situation where, when the user's heating demand for the vehicle air conditioner is relatively small, the target speed of the heater pump may be correspondingly smaller. In this case, the target speed may be lower than the first speed. However, in order to discharge the remaining air in the coolant circuit through the exhaust pipe as much as possible, during the process of starting the vehicle air conditioner, the heater pump can be operated at the first speed for a first period of time, and then the speed can be adjusted to the target speed.

[0094] Step S103: After the rotation speed of the heater water pump of the current vehicle reaches the target rotation speed, the heater water pump of the current vehicle is maintained to operate at the target rotation speed.

[0095] In the embodiment of the present application, after the speed of the heater water pump of the current vehicle has been adjusted and reaches the target speed, the coolant flow in the coolant circuit has reached a level that can meet the heating needs proposed by the user. At this time, the heater water pump of the current vehicle has completed the startup and speed adjustment process, and the heater water pump can be controlled to enter a normal working state, that is, the heater water pump is maintained at the target speed until the temperature in the car reaches the user's requirements or the user modifies the need to use the car air conditioner for heating.

[0096] In combination with the above embodiments, in one implementation, the present application further provides a vehicle air conditioning control method, wherein the first duration is determined according to the following steps:

[0097] First, a first total volume of a coolant circuit where a heater water pump of a calibrated vehicle is located is obtained.

[0098] In the embodiment of the present application, in order to determine the length of time that the heater water pump of the current vehicle should run at the first speed, a test can be performed by calibrating the vehicle, wherein the calibrated vehicle is usually a vehicle of the same model as the current vehicle, or a vehicle with the same type of onboard air conditioner as the current vehicle. This application does not impose any specific restrictions, and the actual situation of the current vehicle can be determined by calibrating the vehicle. First, the total volume in the coolant circuit needs to be obtained, specifically, as Figure 2 As shown, the total volume of the coolant circuit through which the coolant flows during the vehicle air-conditioning heating process includes the heater water pump, heating module and heater core.

[0099] Then, a first coolant flow rate in a coolant circuit where a heater water pump of the calibration vehicle is located is determined at the first speed.

[0100] In the embodiment of the present application, since after starting the heater water pump of the current vehicle, it is necessary to control it to run at the first speed for a first period of time before adjusting the speed, it is necessary to determine the coolant flow in the coolant circuit driven by the heater water pump under the condition that the heater water pump operates at the first speed, and the coolant flow in the coolant circuit when the heater water pump of the calibrated vehicle operates at the first speed is determined as the first coolant flow.

[0101] Finally, the ratio of the first total volume to the first coolant flow rate is determined as the first duration.

[0102] In an embodiment of the present application, after determining the first total volume of the coolant circuit and the first coolant flow rate when the heater pump is running at a first speed in a calibrated vehicle, the time required for the coolant to circulate once in the coolant circuit when the heater pump is running at the first speed can be determined, that is, the ratio of the first total volume of the coolant circuit to the first coolant flow rate. In the present application, for the purpose of reducing the noise generated during the startup process of the vehicle air conditioner after receiving a heating demand, and also considering that the time spent in the startup process of the vehicle air conditioner should not be too long, so as to respond to the user's heating demand in a timely manner, the time required for the coolant to circulate once in the coolant circuit when the heater pump is running at the first speed is determined as the first duration. In an optional embodiment, the first duration can also be increased or decreased based on experience and the specific conditions of the vehicle, which is not restricted in this application.

[0103] In combination with the above embodiments, in one implementation, the present application further provides a vehicle air conditioning control method, wherein the first speed is determined according to the following steps:

[0104] First, a heater water pump of a calibration vehicle is started, and the heater water pump of the calibration vehicle is controlled to operate at different speeds.

[0105] In an embodiment of the present application, in order to determine the first speed of the heater pump during the startup of the onboard air conditioner of the current vehicle, the vehicle can also be calibrated for testing. In order to determine the specific value of the first speed, it is necessary to test and calibrate the heater pump of the vehicle in various situations where it runs at different speeds. Specifically, during the test, the different speeds corresponding to different gears can be adjusted according to the working gear of the heater pump for testing. The speed of the heater pump can also be set to the minimum value and then gradually increased. The specific method is not restricted in this application.

[0106] Then, the amount of noise generated in a coolant circuit where a heater water pump of the calibration vehicle is located at different speeds is determined.

[0107] In the embodiment of the present application, the purpose of setting the heater water pump of the calibrated vehicle to operate at different speeds is to test the amount of noise emitted by the coolant circuit where the heater water pump is located at different speeds. The amount of noise emitted by the coolant circuit at different speeds can be determined by testing the decibel value or by having the tester fill out a noise test card, which can be used as the basis for determining the first speed.

[0108] Finally, the maximum rotational speed at which the noise level is not higher than the first noise threshold is determined as the first rotational speed.

[0109] In the embodiment of the present application, after determining and calibrating the noise level generated by the coolant circuit of the vehicle's heater water pump at different speeds, the noise level can be compared with a first noise threshold, thereby determining the maximum speed that is no higher than the first noise threshold as the first speed. In this way, the first speed of the heater water pump can be determined with reasonable accuracy, while minimizing noise while ensuring the efficiency of the heater water pump, thereby minimizing the impact on the efficiency of the vehicle air conditioner during startup.

[0110] In an optional embodiment, the minimum speed for normal operation of the heater water pump can also be set to the first speed to ensure that after the heater water pump is turned on, the noise level generated by driving the coolant to flow in the coolant circuit is minimized. However, correspondingly, since the minimum speed is usually lower than the first speed proposed in this application, the efficiency of discharging the residual air in the coolant circuit during the first operating time is lower, and it will take more time to adjust to the target speed.

[0111] In combination with the above embodiments, in one implementation, the present application further provides a vehicle air conditioning control method, which adjusts the speed of the heater water pump of the current vehicle based on the target speed, specifically including the following contents:

[0112] With the target speed as a target, the speed of the heater water pump of the current vehicle is adjusted under the condition that the speed change rate of the heater water pump of the current vehicle does not exceed a speed change rate threshold.

[0113] In an embodiment of the present application, after the heater pump of the current vehicle is controlled to operate at a first speed for a first duration, it is considered that the air remaining in the coolant circuit has been discharged through the exhaust pipe as much as possible, and then the speed of the heater pump needs to be increased to the target speed to meet the user's air conditioning and heating needs. In this process, the speed of the heater pump is increased from the first speed to the target speed. However, if the speed of the heater pump is increased from the first speed to the target speed too quickly, the speed change rate of the heater pump may be too high, causing noise in the coolant circuit, affecting the user's experience. Therefore, the speed of the heater pump of the current vehicle can be adjusted under the condition that the speed change rate of the heater pump of the current vehicle does not exceed the speed change rate threshold, to avoid a bad experience for the user due to too fast a speed change.

[0114] In an optional embodiment, if the user chooses to turn off the air conditioner before the heater pump of the vehicle air conditioner reaches the target speed, in order to avoid the impact of the sudden stop of the heater pump, the rate of change of the heater pump's speed when it decreases can also be controlled under the condition that it does not exceed the speed change rate threshold.

[0115] The speed change rate threshold is determined according to the following steps:

[0116] First, a heater water pump of a calibration vehicle is started, and the heater water pump of the calibration vehicle is controlled to operate at the first speed.

[0117] In an embodiment of the present application, in order to determine the speed change rate threshold of the heater water pump of the current vehicle, a test can also be performed through a calibrated vehicle. First, the heater water pump of the calibrated vehicle can be started and run at a first speed. Since in the process of starting the onboard air conditioner of the current vehicle, the heater water pump of the current vehicle is first started and controlled to run at the first speed, and then the speed is adjusted. Therefore, in the process of testing through a calibrated vehicle, the same prerequisites need to be maintained, and the test should be consistent with the actual situation after the user drives the current vehicle and puts forward the demand for air conditioning and heating.

[0118] Then, after the heater water pump of the calibration vehicle is controlled to run at the first speed for the first duration, the speed of the heater water pump of the calibration vehicle is adjusted at different speed change rates with the calibration speed as the target.

[0119] In an embodiment of the present application, after the heater pump of the calibrated vehicle is controlled to operate at a first speed for a first duration, it can be considered that the coolant circuit where the heater pump is located in the calibrated vehicle is consistent with the coolant circuit state of the heater pump located in the current vehicle after the user starts the onboard air conditioner for the first duration, and the speed change rate threshold can be determined. Specifically, by setting a calibrated speed as a target, the heater pump of the calibrated vehicle is adjusted to the calibrated speed through different speed change rates, wherein the calibrated speed can be any value greater than the first speed, which is the end point of the speed adjustment used by the calibrator to test the speed change rate threshold. In an optional embodiment, the calibrated speed can be set to the maximum speed of the heater pump under normal operation, which is not required by the present application.

[0120] Next, the amount of noise generated by the coolant circuit where the heater water pump of the calibration vehicle is located at different speed change rates is determined.

[0121] In the embodiment of the present application, the purpose of adjusting the speed of the heater water pump of the calibrated vehicle according to different speed change rates is to test the amount of noise emitted in the coolant circuit where the heater water pump is located at different speed change rates. As mentioned above, the amount of noise emitted in the coolant circuit at different speed change rates can be determined by testing the decibel value or by having the tester fill out a noise test card, which can be used as the basis for determining the speed change rate threshold.

[0122] Finally, the maximum rotation speed change rate at which the noise amount is not higher than the first noise threshold is determined as the rotation speed change rate threshold.

[0123] In an embodiment of the present application, after determining the noise level generated by the coolant circuit of the vehicle's heater water pump at different speed change rates and calibrating the noise level, the noise level can be compared with a first noise threshold, thereby determining the maximum speed change rate that is no greater than the first noise threshold as the speed change rate threshold. As described above, determining the speed change rate threshold in this manner can minimize noise while maximizing the efficiency of the heater water pump when it is ramped from the first speed to the target speed, thereby minimizing the impact on the efficiency of the vehicle air conditioner during startup.

[0124] In combination with the above embodiments, in one implementation, the present application further provides a vehicle air conditioning control method, which takes a target speed as a target and adjusts the speed of the heater water pump of the current vehicle under the condition that the speed change rate of the heater water pump of the current vehicle does not exceed a speed change rate threshold, specifically including the following contents:

[0125] First, a speed increase amount of the heater water pump of the current vehicle is determined according to the first speed and the target speed.

[0126] In the embodiments of the present application, when the target rotating speed is used as the target to adjust the rotating speed of the current vehicle's heater water pump, first, the difference between the current rotating speed of the heater water pump of the current vehicle, i.e., the first rotating speed, and the target rotating speed is used to determine the rotating speed increase amount that the heater water pump of the current vehicle needs to increase.

[0127] Then, the rotating speed change rate threshold or the rotating speed change rate less than the rotating speed change rate threshold is determined as the first rotating speed change rate.

[0128] In the embodiments of the present application, the target rotating speed is used as the target to adjust the rotating speed change rate of the heater water pump of the current vehicle under the condition that the change rate does not exceed the change rate threshold, and thus the change rate, i.e., the first rotating speed change rate, at which the rotating speed of the heater water pump of the current vehicle is adjusted at this time can be determined according to the rotating speed change rate threshold, where the first rotating speed change rate can be any value not greater than the rotating speed change rate threshold. In an alternative embodiment, the rotating speed change rate threshold can be determined as the first rotating speed change rate under normal circumstances. In this way, the rotating speed of the heater water pump can be increased to the target rotating speed as soon as possible to meet the user's air conditioning and heating demand under the condition that the noise level emitted by the cooling liquid circuit in which the heater water pump is located is not higher than the first noise threshold.

[0129] Next, the ratio of the rotating speed increase amount to the first change rate is determined as the second time length for adjusting the rotating speed of the heater water pump of the current vehicle.

[0130] In the embodiments of the present application, after the first rotating speed change rate of the heater water pump of the current vehicle is determined, the second time length for adjusting the rotating speed of the heater water pump of the current vehicle can be determined according to the ratio between the rotating speed increase amount and the first change rate determined above.

[0131] In this way, according to the vehicle-mounted air conditioner control method proposed in the present application, the total time length for starting the vehicle-mounted air conditioner of the current vehicle after considering the user's air conditioning and heating demand is the sum of the first time length and the second time length, where the first time length is a fixed value determined by testing the calibration vehicle, and the second time length has different values according to the user's heating demand.

[0132] Finally, the rotating speed of the heater water pump of the current vehicle is continuously adjusted at the first rotating speed change rate for the second time length.

[0133] In an embodiment of the present application, after determining the first speed change rate for adjusting the speed of the heater water pump of the current vehicle and the second duration required for the adjustment process, the speed of the heater water pump of the current vehicle can be continuously adjusted at the first change rate according to the second duration, so that after the adjustment lasting for the second duration, the heater water pump of the current vehicle is adjusted from the first speed to the target speed, so that the coolant flow in the coolant circuit reaches a level that can meet the heating needs proposed by the user.

[0134] In combination with the above embodiments, in one implementation, the present application further provides a vehicle air conditioning control method, wherein the first noise threshold is determined according to the following steps:

[0135] First, the blower of the calibration vehicle is started and controlled to operate at a first gear, where the first gear is a minimum gear for the blower of the calibration vehicle to operate normally.

[0136] In the embodiment of the present application, to determine the value of the first noise threshold, a test can also be performed using a calibration vehicle. First, the blower of the calibration vehicle can be started and operated in the first gear. The blower, as part of the vehicle air conditioner, is used to blow through the heater core so that the blown air is heated by the heater core and then blown into the vehicle body space where the user is located, thereby realizing the heating function of the vehicle air conditioner. Therefore, in response to the user's air conditioning and heating needs, the blower in the vehicle air conditioner will operate at a target gear that is not lower than the first gear. Therefore, in the process of determining the first noise threshold, the blower of the calibration vehicle is controlled to operate in the first gear, i.e., the minimum gear for normal operation, so as to determine the minimum noise level emitted by the blower under normal operation.

[0137] Then, the first noise threshold is determined according to the noise level emitted by the vehicle air conditioner of the calibration vehicle when the blower operates in the first gear.

[0138] In an embodiment of the present application, when the blower is operating in the first gear, the noise level emitted by the vehicle air conditioner of the calibrated vehicle is determined as the first noise threshold. Since the sound generated by the blower during operation is usually fixed and can be considered to be acceptable to the user, the minimum noise level emitted by the blower during normal operation of the vehicle air conditioner is determined as the maximum noise level acceptable to the user, and this noise level is determined as the first noise threshold. This ensures that, through the vehicle air conditioner control method proposed in this application, after responding to the user's air conditioning and heating needs, the noise emitted does not exceed the first noise threshold until the heater water pump of the current vehicle is maintained at the target speed. This effectively reduces the water flow impact sound generated by the high-speed rotation of the heater water pump during the heating startup process of the vehicle air conditioner, thereby improving the user experience.

[0139] Moreover, not only during the process of starting the vehicle air conditioner as proposed in this application, but also during normal operation, even if there is no air in the coolant circuit, the flow of coolant will produce a certain water flow sound, and the faster the speed of the heater water pump, the louder the water flow sound. Therefore, by starting the blower when turning on the air conditioner, the water flow sound in the coolant circuit can be covered up to a certain extent by the wind sound generated by the blower.

[0140] In combination with the above embodiments, in one implementation, the present application further provides a vehicle air conditioning control method, which specifically further includes the following contents before the speed of the heater water pump of the current vehicle reaches the target speed:

[0141] First, a second rotational speed of the heater water pump of the current vehicle is determined according to a minimum coolant flow rate required for normal operation of the heating module.

[0142] In an embodiment of the present application, after responding to the user's air-conditioning and heating needs, the control of the vehicle air-conditioning also includes the control of the heating module of the vehicle air-conditioning. The heating module is used to heat the coolant in the coolant circuit, so that the heated coolant transfers heat to the heater core, and the wind generated by the blower brings the heat of the heater core into the user's vehicle interior space. Therefore, in the process of heating through the vehicle air-conditioning, the heating module in the vehicle air-conditioning also needs to be controlled.

[0143] Generally speaking, a heating module has a minimum coolant flow rate limit to meet its normal operating conditions. If the coolant flow rate through the heating module is less than this minimum coolant flow rate, the heat generated by the heating module may not be transferred to the coolant in a timely manner, causing the heating module to report a fault or, in more serious cases, even malfunction. Therefore, it is necessary to determine the second speed of the heater water pump of the current vehicle based on the minimum coolant flow rate required for the normal operation of the selected heating module. The second speed is the minimum speed corresponding to the minimum coolant flow rate required for the normal operation of the heating module.

[0144] Then, during a period in which the rotation speed of the heater water pump of the current vehicle is less than the second rotation speed, the heating module is turned off.

[0145] In the embodiment of the present application, due to the use of the vehicle air-conditioning control method proposed in the present application, during the first and second time periods after the air-conditioning is turned on, the speed of the heater water pump may not reach the target speed and may be less than the second speed. At this time, if the heating module is turned on, a malfunction may occur. Therefore, during the period when the speed of the heater water pump of the current vehicle is less than the second speed, the heating module is turned off.

[0146] Finally, after the rotation speed of the heater water pump of the current vehicle reaches the second rotation speed, the heating module is turned on.

[0147] In an embodiment of the present application, after the speed of the heater water pump of the current vehicle reaches the second speed, the coolant flow in the coolant circuit can meet the minimum coolant flow requirement for the normal operation of the heating module. At this time, the heating module is turned on again, thereby achieving the goal of protecting the heating module in the vehicle air conditioner from normal operation due to the adjustment of the speed of the heater water pump while adopting the vehicle air conditioner control method proposed in this application.
