[0016] Please see Figures 1 to 6 , Figure 1 This is a schematic flowchart of a vehicle heating control method provided in an embodiment of the present invention; Figure 2A schematic diagram of a sub-process of the vehicle heating control method provided in an embodiment of the present invention; Figure 3 This is another schematic diagram of a sub-process of the vehicle heating control method provided in an embodiment of the present invention; Figure 4 This is another sub-process diagram of the vehicle heating control method provided in an embodiment of the present invention; Figure 5 This is another sub-process diagram of the vehicle heating control method provided in an embodiment of the present invention; Figure 6 This is another schematic diagram of a sub-process of the vehicle heating control method provided in an embodiment of the present invention. For example... Figures 1 to 6 As shown, this embodiment of the invention provides a vehicle heating control method, applied in the controller of a vehicle heating control system, which is used in a vehicle; the controller is communicatively connected to the compressor, battery expansion valve, and temperature detector in the vehicle heating control system; the compressor is used to control the heat pump heating cycle in the vehicle cabin; the battery expansion valve is used to control the heating of the heat pump battery in the vehicle.

[0017] The vehicle heating control method includes the following steps S110-S140.

[0018] S110, Obtain the vehicle's current heating mode.

[0019] In this embodiment, the controller obtains the current heating mode of the vehicle. The current heating mode includes two heating methods: cabin heating and battery heating. Specifically, it can include four heating situations: cabin heating off and battery heating off, cabin heating on and battery heating on, cabin heating on and battery heating off, and cabin heating off and battery heating on.

[0020] As can be seen from the above embodiments, after determining the current heating mode, the controller can perform subsequent targeted processing based on the current heating mode to ensure the accuracy of the processing and thus improve control efficiency.

[0021] S120. If the current heating mode is that the cabin heating is on and the battery heating is on, then the temperature detector is used to detect and process the external environment of the vehicle to obtain a first temperature value.

[0022] In this embodiment, when the controller acquires the current heating mode, it determines the current heating mode. If the current heating mode is that the cabin heating is on and the battery heating is on, the controller uses the temperature detector to detect and process the external environment of the vehicle to obtain a first temperature value, and then enters the heating linkage control. The first temperature value refers to the temperature of the external environment temperature detector installed on the vehicle's thermal management unit. This temperature detector can be an ambient temperature sensor, meaning it can be located in the external environment.

[0023] When the controller obtains the current heating mode, it determines the current heating mode. If the current heating mode is that the cabin heating is on and the battery heating is off, or the cabin heating is off and the battery heating is on, then it does not enter the heating linkage control.

[0024] As can be seen from the above embodiments, after determining the first temperature value, the controller can perform subsequent targeted processing based on the first temperature value to ensure the accuracy of the processing and thus improve control efficiency.

[0025] S130. The control mode is obtained by judging the first temperature value using a judgment strategy.

[0026] In this embodiment, after obtaining the first temperature value, the controller can use a judgment strategy to judge and process the first temperature value to obtain a control mode.

[0027] In one embodiment, such as Figures 1 to 6 As shown, the step of using a judgment strategy to judge and process the first temperature value to obtain a control mode includes: S131. If the first temperature value is greater than and equal to the first temperature threshold, then the control mode is the first control mode. S132. If the first temperature value is less than the first temperature threshold, then the control mode is the second control mode.

[0028] In this embodiment, as Figures 1 to 6 As shown, the controller compares the first temperature value with a preset first temperature threshold. When the controller determines that the first temperature value is greater than or equal to the first temperature threshold, it determines that the control mode is a first control mode. When the controller determines that the first temperature value is less than the first temperature threshold, it determines that the control mode is a second control mode.

[0029] Specifically, based on specific experiments, the first temperature threshold can be -15℃.

[0030] As can be seen from the above embodiments, when the first temperature value is greater than and equal to the first temperature threshold, the control mode is the first control mode; when the first temperature value is less than the first temperature threshold, the control mode is the second control mode. Therefore, by comparing the first temperature value and the first temperature threshold, accurate control of the control mode is achieved, thereby improving control efficiency and precisely controlling the linkage between cabin heating and battery heating, ensuring the efficient, safe, and comfortable operation of air-conditioned vehicles.

[0031] S140. The compressor, the battery expansion valve, and the temperature detector are heated according to the control mode.

[0032] In this embodiment, after determining that the control mode is the first control mode or the second control mode, the compressor, the battery expansion valve and the temperature detector can be heated according to the control mode.

[0033] In one embodiment, such as Figures 1 to 6 As shown, heating control of the compressor, the battery expansion valve, and the temperature detector according to the control mode includes: S141. If the control mode is the first control mode, then the temperature detector is controlled to detect and process the vehicle's in-vehicle outlet pipe to obtain a second temperature value, and the temperature detector is controlled to detect and process the vehicle's battery to obtain a third temperature value. S142. If the second temperature value is greater than and equal to the second temperature threshold, and the third temperature value is greater than and equal to the third temperature threshold, then control the frequency of the compressor to decrease by the first frequency value, and control the opening of the battery expansion valve to decrease by the first threshold value. S143. If the second temperature value is greater than and equal to the second temperature threshold, and the third temperature value is less than the third temperature threshold, then control the frequency of the compressor to decrease the first frequency value, and control the opening of the battery expansion valve to increase the first threshold value.

[0034] In this embodiment, as Figures 1 to 6 As shown, when the controller determines that the control mode is the first control mode, it controls the temperature detector to detect and process the outlet pipe of the vehicle's interior to obtain a second temperature value, and controls the temperature detector to detect and process the vehicle's battery to obtain a third temperature value. The second temperature value is the outlet pipe temperature of the interior heat exchanger located on the vehicle's thermal management unit; that is, the temperature detector can be located at the outlet pipe of the interior heat exchanger.

[0035] The controller compares the second temperature value with a preset second temperature threshold and compares the third temperature value with a preset third temperature threshold. When the controller determines that the second temperature value is greater than or equal to the second temperature threshold and the third temperature value is greater than or equal to the third temperature threshold, it controls the compressor frequency to decrease by a preset first frequency value. That is, it obtains the current frequency of the compressor and uses the difference between the current frequency and the first frequency value as the compressor's update frequency, controlling the compressor's operation with the compressor's update frequency. Simultaneously, it controls the opening of the battery expansion valve to decrease by a preset first threshold. That is, it obtains the current opening of the battery expansion valve and uses the difference between the current opening and the first threshold value as the battery expansion valve's update opening, controlling the battery expansion valve's operation with the battery expansion valve's update opening.

[0036] The controller compares the second temperature value with a preset second temperature threshold and compares the third temperature value with a preset third temperature threshold. When the controller determines that the second temperature value is greater than or equal to the second temperature threshold and the third temperature value is less than the third temperature threshold, it controls the compressor frequency to decrease by a preset first frequency value, that is, it obtains the current frequency of the compressor and uses the difference between the current frequency and the first frequency value as the compressor's update frequency, and controls the compressor to operate using the compressor's update frequency. Simultaneously, it controls the opening of the battery expansion valve to increase by a preset first threshold value, that is, it obtains the current opening of the battery expansion valve and uses the sum of the current opening and the first threshold value as the battery expansion valve's update opening, and controls the battery expansion valve to operate using the battery expansion valve's update opening.

[0037] Specifically, based on specific experiments, the second temperature threshold can be 30℃, the third temperature threshold can be 40℃, the first frequency value can be 10Hz, and the first threshold can be 100B.

[0038] As can be seen from the above embodiments, when the control mode is the first control mode, the detected second and third temperature values ​​are compared with the corresponding preset second and third temperature thresholds, respectively, to achieve precise control of the compressor frequency and the opening degree of the battery expansion valve. Therefore, different heating linkage controls are adopted according to different temperature judgment conditions, thereby improving control efficiency and precisely controlling the linkage between cabin heating and battery heating to ensure the efficient, safe, and comfortable operation of the air-conditioned vehicle.

[0039] In one embodiment, such as Figures 1 to 6As shown, if the control mode is the first control mode, then after controlling the temperature detector to detect and process the vehicle's in-vehicle outlet pipe to obtain a second temperature value, and controlling the temperature detector to detect and process the vehicle's battery to obtain a third temperature value, the method further includes: S144. If the second temperature value is less than the second temperature threshold and the third temperature value is greater than and equal to the third temperature threshold, then control the compressor frequency to increase the second frequency value and control the opening of the battery expansion valve to decrease the second threshold value. S145. If the second temperature value is less than the second temperature threshold and the third temperature value is less than the third temperature threshold, then control the compressor frequency to increase the second frequency value and control the opening of the battery expansion valve to decrease the second threshold value.

[0040] In this embodiment, as Figures 1 to 6 As shown, when the controller determines that the control mode is the first control mode, it controls the temperature detector to detect and process the outlet pipe of the vehicle's interior to obtain a second temperature value, and controls the temperature detector to detect and process the vehicle's battery to obtain a third temperature value. The second temperature value is the outlet pipe temperature of the interior heat exchanger located on the vehicle's thermal management unit; that is, the temperature detector can be located at the outlet pipe of the interior heat exchanger.

[0041] The controller compares the second temperature value with a preset second temperature threshold and compares the third temperature value with the preset third temperature threshold. When the controller determines that the second temperature value is less than the second temperature threshold and the third temperature value is greater than or equal to the third temperature threshold, it controls the compressor frequency to increase by a preset second frequency value, i.e., it obtains the current frequency of the compressor and uses the sum of the current frequency and the second frequency value as the compressor's update frequency, controlling the compressor's operation with the compressor's update frequency. Simultaneously, it controls the opening of the battery expansion valve to decrease by a preset second threshold value, i.e., it obtains the current opening of the battery expansion valve and uses the difference between the current opening and the second threshold value as the battery expansion valve's update opening, controlling the battery expansion valve's operation with the battery expansion valve's update opening.

[0042] The controller compares the second temperature value with a preset second temperature threshold and compares the third temperature value with the preset third temperature threshold. When the controller determines that the second temperature value is less than the second temperature threshold and the third temperature value is less than the third temperature threshold, it controls the compressor frequency to increase by a preset second frequency value, that is, it obtains the current frequency of the compressor and uses the sum of the current frequency and the second frequency value as the compressor's update frequency, and controls the compressor operation with the compressor's update frequency. At the same time, it controls the opening of the battery expansion valve to decrease by a preset second threshold value, that is, it obtains the current opening of the battery expansion valve and uses the difference between the current opening of the battery expansion valve and the second threshold value as the battery expansion valve's update opening, and controls the battery expansion valve operation with the battery expansion valve's update opening.

[0043] Specifically, based on specific experiments, the second temperature threshold can be 30℃, the third temperature threshold can be 40℃, the second frequency value can be 15Hz, and the second threshold can be 200B.

[0044] As can be seen from the above embodiments, when the control mode is the first control mode, the detected second and third temperature values ​​are compared with the corresponding preset second and third temperature thresholds, respectively, to achieve precise control of the compressor frequency and the opening degree of the battery expansion valve. Therefore, different heating linkage controls are adopted according to different temperature judgment conditions, thereby improving control efficiency and precisely controlling the linkage between cabin heating and battery heating to ensure the efficient, safe, and comfortable operation of the air-conditioned vehicle.

[0045] In one embodiment, such as Figures 1 to 6 As shown, the heating control of the compressor, the battery expansion valve, and the temperature detector according to the control mode includes: S146. If the control mode is the second control mode, then control the temperature detector to detect and process the battery of the vehicle to obtain a fourth temperature value. S147. If the fourth temperature value is less than the fourth temperature threshold, the frequency of the compressor is increased by the third frequency value, and the opening of the battery expansion valve is increased by the third threshold value.

[0046] In this embodiment, as Figures 1 to 6 As shown, when the controller determines that the control mode is the second control mode, it controls the temperature detector to detect and process the vehicle's battery to obtain a fourth temperature value. The third temperature value is the temperature of the battery in the vehicle, meaning the temperature detector can be located at the battery location.

[0047] The controller compares the fourth temperature value with a preset fourth temperature threshold, and further compares the fourth temperature value with the preset fourth temperature threshold. When the controller determines that the fourth temperature value is less than the fourth temperature threshold, it controls the compressor frequency to increase by a preset third frequency value, that is, it obtains the current frequency of the compressor and uses the sum of the current frequency and the third frequency value as the compressor's update frequency, and controls the compressor to operate using the compressor's update frequency. Simultaneously, it controls the opening of the battery expansion valve to increase by a preset third threshold, that is, it obtains the current opening of the battery expansion valve and uses the sum of the current opening and the third threshold value as the battery expansion valve's update opening, and controls the battery expansion valve to operate using the battery expansion valve's update opening.

[0048] Specifically, based on specific experiments, the third temperature threshold can be 30℃; the third frequency value can be 20Hz; and the third threshold can be 150B.

[0049] As can be seen from the above embodiments, when the control mode is the second control mode, the detected fourth temperature value is compared with the corresponding preset fourth temperature threshold to achieve precise control of the compressor frequency and the opening degree of the battery expansion valve. Therefore, different heating linkage controls are adopted according to different temperature judgment conditions, thereby improving control efficiency, accurately controlling the linkage control between cabin heating and battery heating, and ensuring the efficient, safe, and comfortable operation of air-conditioned vehicles.

[0050] In one embodiment, such as Figures 1 to 6 As shown, if the control mode is the second control mode, after controlling the temperature detector to detect and process the vehicle's battery to obtain a fourth temperature value, the method further includes: S148. If the fourth temperature value is greater than and equal to the fourth temperature threshold, then control the opening of the battery expansion valve to reduce the third threshold value.

[0051] In this embodiment, as Figures 1 to 6 As shown, when the controller determines that the control mode is the second control mode, it controls the temperature detector to detect and process the vehicle's battery to obtain a fourth temperature value. The third temperature value is the temperature of the battery in the vehicle, meaning the temperature detector can be located at the battery location.

[0052] The controller compares the fourth temperature value with a preset fourth temperature threshold. When the controller determines that the fourth temperature value is greater than or equal to the fourth temperature threshold, the compressor frequency remains unchanged, i.e., the current frequency of the compressor is obtained, and the compressor operation is controlled by the current frequency of the compressor. At the same time, the controller controls the opening of the battery expansion valve to decrease by a preset third threshold, i.e., the current opening of the battery expansion valve is obtained, and the difference between the current opening of the battery expansion valve and the third threshold is used as the updated opening of the battery expansion valve, and the operation of the battery expansion valve is controlled by the updated opening of the battery expansion valve.

[0053] Specifically, the third threshold value can be 150B, as determined by specific experiments.

[0054] As can be seen from the above embodiments, when the control mode is the second control mode, the detected fourth temperature value is compared with the corresponding preset fourth temperature threshold to achieve precise control of the compressor frequency and the opening degree of the battery expansion valve. Therefore, different heating linkage controls are adopted according to different temperature judgment conditions, thereby improving control efficiency, accurately controlling the linkage control between cabin heating and battery heating, and ensuring the efficient, safe, and comfortable operation of air-conditioned vehicles.

[0055] In one embodiment, such as Figures 1 to 6 As shown, after controlling the heating of the compressor, the battery expansion valve, and the temperature detector according to the control mode, the method further includes: The temperature detector is reused to detect and process the external environment of the vehicle to obtain the first temperature value, and the first temperature value is judged and processed using a judgment strategy to obtain the control mode.

[0056] In this embodiment, as Figures 1 to 6 As shown, after heating the compressor, battery expansion valve, and temperature detector according to the control mode, the temperature detector can continuously detect for a preset detection time, and then return to steps S120 and S130. That is, the temperature detector detects and processes the external environment of the vehicle to obtain the first temperature value, and a judgment strategy is used to judge and process the first temperature value to obtain the control mode, thereby redetermining the control mode. The detection time is set to ensure detection accuracy.

[0057] The detection duration may include a first detection duration, a second detection duration, a third detection duration, and a fourth detection duration.

[0058] When the current heating mode of the vehicle is obtained, and after the first detection period has elapsed, the controller determines the current heating mode.

[0059] When the control mode is the first control mode, the second temperature value is greater than and equal to the second temperature threshold, and the compressor, the battery expansion valve and the temperature detector are heated according to the control mode, after the second detection time, the process returns to steps S120 and S130 to redetermine the control mode.

[0060] When the control mode is the first control mode, the second temperature value is less than the second temperature threshold, and the compressor, the battery expansion valve and the temperature detector are heated according to the control mode, after the third detection time, the process returns to steps S120 and S130 to redetermine the control mode.

[0061] When the control mode is the second control mode, and the compressor, the battery expansion valve and the temperature detector are heated according to the control mode, after the fourth detection period, the process returns to steps S120 and S130 to redetermine the control mode.

[0062] Specifically, based on the specific experiments, the first detection duration is 30 seconds, the second detection duration is 40 seconds, the third detection duration is 50 seconds, and the fourth detection duration is 60 seconds.

[0063] As can be seen from the above embodiments, by setting the detection duration, the accuracy of detection can be ensured, and the control mode can be accurately controlled, thereby improving control efficiency. This allows for precise control of the linkage between cabin heating and battery heating, ensuring the efficient, safe, and comfortable operation of air-conditioned vehicles.

[0064] Please see Figure 7 , Figure 7 This is a schematic block diagram of a vehicle heating control system 200 provided in an embodiment of the present invention. Figure 7 As shown, this embodiment of the invention provides a vehicle heating control system 200 that implements the method described above. The system is applied in the controller of a vehicle heating control system, which is used in a vehicle. The controller is communicatively connected to the compressor, battery expansion valve, and temperature detector in the vehicle heating control system. The compressor controls the heat pump heating cycle in the vehicle cabin, and the battery expansion valve controls the heating of the heat pump battery in the vehicle.

[0065] The vehicle heating control system 200 includes: an acquisition unit 210, a detection unit 220, a judgment unit 230, and a heating control unit 240.

[0066] The acquisition unit 210 is used to acquire the current heating mode of the vehicle.

[0067] In this embodiment, the controller obtains the current heating mode of the vehicle. The current heating mode includes two heating methods: cabin heating and battery heating. Specifically, it can include four heating situations: cabin heating off and battery heating off, cabin heating on and battery heating on, cabin heating on and battery heating off, and cabin heating off and battery heating on.

[0068] The detection unit 220 is used to detect and process the external environment of the vehicle using the temperature detector to obtain a first temperature value if the current heating mode is that the cabin heating is on and the battery heating is on.

[0069] In this embodiment, when the controller acquires the current heating mode, it determines the current heating mode. If the current heating mode is that both the cabin heating and battery heating are on, the controller uses the temperature detector to detect and process the external environment of the vehicle to obtain a first temperature value, and then enters the heating linkage control. The first temperature value refers to the temperature measured by the external environment temperature detector installed on the vehicle's thermal management unit. This temperature detector can be an ambient temperature sensor, meaning it can be located in the external environment.

[0070] When the controller obtains the current heating mode, it determines the current heating mode. If the current heating mode is that the cabin heating is on and the battery heating is off, or the cabin heating is off and the battery heating is on, then it does not enter the heating linkage control.

[0071] The judgment unit 230 is used to judge the first temperature value using a judgment strategy to obtain a control mode.

[0072] In this embodiment, after obtaining the first temperature value, the controller can use a judgment strategy to judge and process the first temperature value to obtain a control mode.

[0073] The heating control unit 240 is used to control the heating of the compressor, the battery expansion valve and the temperature detector according to the control mode.

[0074] In this embodiment, after determining that the control mode is the first control mode or the second control mode, the compressor, the battery expansion valve and the temperature detector can be heated according to the control mode.

[0075] In some embodiments, when the judgment unit 230 performs the processing step of judging the first temperature value using a judgment strategy to obtain a control mode, it is specifically used for: If the first temperature value is greater than and equal to the first temperature threshold, then the control mode is the first control mode; If the first temperature value is less than the first temperature threshold, then the control mode is the second control mode.

[0076] In some embodiments, when the heating control unit 240 performs the processing step of heating the compressor, the battery expansion valve, and the temperature detector according to the control mode, it is specifically used for: If the control mode is the first control mode, then the temperature detector is controlled to detect and process the vehicle's in-vehicle outlet pipe to obtain a second temperature value, and the temperature detector is controlled to detect and process the vehicle's battery to obtain a third temperature value.
