[0045] In an embodiment of the present invention, in response to the vehicle air conditioner being turned on, the ambient temperature, user set temperature, vehicle interior temperature and sunlight intensity are obtained; the judgment condition is determined according to the ambient temperature, user set temperature, vehicle interior temperature and sunlight intensity; the judgment condition is compared with the preset condition to obtain a comparison result; in response to the comparison result indicating that the judgment condition meets the preset condition, the vehicle engine output power is controlled to increase to increase the engine heat. Through the above method, when the air conditioning heating capacity is insufficient, that is, the judgment condition meets the preset condition, the vehicle engine output power can be controlled to increase to increase the engine heat, and the insufficient air conditioning heating capacity can be compensated by directly generating heat through the engine, without the need to add a higher power PTC heater, thereby solving the problem that the heat generated by the vehicle engine becomes less, when the heat is insufficient during winter heating, a high-power PTC heater needs to be added to improve the heating effect, and the vehicle weight, that is, the technical problem of increased operating cost, is increased.

[0046] Optionally, the judgment conditions are determined based on the ambient temperature, the user-set temperature, the temperature inside the vehicle and the sunlight intensity, including: determining the ambient temperature as the judgment condition; comparing the judgment condition with the preset condition to obtain a comparison result, including: comparing the ambient temperature with the first preset temperature to obtain a comparison result.

[0047] Optionally, the judgment conditions are determined according to the ambient temperature, the temperature set by the user, the temperature inside the vehicle and the sunlight intensity, including: determining the target air outlet temperature by using a preset formula according to the ambient temperature, the temperature set by the user, the temperature inside the vehicle and the sunlight intensity; determining the difference between the target air outlet temperature and the ambient temperature as the judgment condition; comparing the judgment condition with the preset condition to obtain a comparison result, including: comparing the difference between the target air outlet temperature and the ambient temperature with a second preset temperature to obtain a comparison result.

[0048] Optionally, the vehicle air conditioning control method also includes: obtaining the temperature damper position of the vehicle air conditioning; determining the temperature damper position of the vehicle air conditioning as a judgment condition; comparing the judgment condition with a preset condition to obtain a comparison result, including: comparing the temperature damper position with a preset damper position to obtain a comparison result.

[0049] Optionally, the vehicle air conditioning control method also includes: obtaining the current air volume of the vehicle air conditioning; using the current air volume as a judgment condition; comparing the judgment condition with a preset condition to obtain a comparison result, including: comparing the current air volume with a preset air volume threshold to obtain a comparison result.

[0050] Optionally, the vehicle air conditioning control method also includes: obtaining the engine water temperature of the vehicle; using the engine water temperature as a judgment condition; comparing the judgment condition with a preset condition to obtain a comparison result, including: comparing the engine water temperature with a preset water temperature threshold to obtain a comparison result.

[0051] Optionally, the vehicle air conditioning control method also includes: obtaining the average output power of the engine calculation cycle of the vehicle in the current stage; using the average output power as a judgment condition; comparing the judgment condition with a preset condition to obtain a comparison result, including: comparing the output power with a preset power threshold to obtain a comparison result.

[0052] Optionally, in response to the comparison result indicating that the judgment condition meets the preset condition, the engine output power of the vehicle is controlled to increase so as to increase the engine heat, including: in response to the comparison result indicating that the judgment condition meets the preset condition, the engine is controlled to change from operating in an economic zone to operating in a low efficiency zone so as to increase the engine heat.

[0053] Reference Figure 2When the air conditioner is used for heating, the water pump 1 runs to transfer the heat generated by the engine 2 and the PTC heater 3 to the warm air 4. After the warm air 4 exchanges heat with the air outside the car, the hot air is blown into the car for heating.

[0054] Reference Figure 3 After the air conditioner is turned on, the air conditioner controller calculates according to the ambient temperature, the temperature inside the car, the user-set temperature, the sunlight intensity, the set air volume, the engine water temperature, and the damper position, and controls the temperature damper motor to run to the corresponding position. According to the calculation result, the heating boost request is output to the engine controller. The engine controller calculates the engine output power according to the engine torque and engine speed, and adjusts the engine working MAP as needed.

[0055] Reference Figure 4 The vehicle air conditioning control method described in the above embodiment is exemplarily implemented as follows:

[0056] S1: Air conditioning is on.

[0057] S2: Target air outlet temperature calculation: The air conditioning controller calculates the target air outlet temperature based on the Figure 3 The target air outlet temperature is calculated based on the ambient temperature, vehicle interior temperature, user set temperature, and sunlight intensity, and can be corrected in the laboratory and road test calibration.

[0058] S3: Determine whether the ambient temperature is lower than a threshold value (first preset temperature): Different vehicles require different amounts of heat for heating. It is necessary to determine through tests the minimum ambient temperature that the vehicle heating system can maintain to be comfortable in the vehicle, and use this as the judgment threshold.

[0059] S4: Determine whether the target air outlet temperature minus the ambient temperature is higher than a threshold value (a second preset temperature): Subtract the ambient temperature from the target air outlet temperature calculated in step S2 and compare it with the set threshold value.

[0060] S5: The air conditioning controller adjusts the temperature damper in the air conditioning box to the hottest end (preset damper position) to ensure maximum heat output from the air conditioning to the vehicle.

[0061] S6: Determine whether the air volume of the air conditioner is greater than a threshold value (preset air volume threshold value), and set a threshold value based on the heat demand of the air conditioner under different air volumes obtained through simulation calculation or test verification. The threshold value is different under different working conditions and needs to be determined by looking up a table.

[0062] S7: Whether the engine water temperature is lower than a threshold value (preset water temperature threshold value), which corresponds to the target air outlet temperature calculated in step S2, and also needs to be judged by looking up a table.

[0063] S8: The air conditioning controller determines and outputs a heating boost request signal to the engine controller. This is executed when the judgments in steps S3, S4, S6, and S7 are all met. To avoid the impact of output signal fluctuations on engine operation, the output signal is detected and output in a fixed cycle (such as 30 seconds).

[0064] S9: The engine controller determines whether the average output power in the current engine calculation cycle (such as within 20 seconds) exceeds a threshold (preset power threshold). The threshold is determined based on the output power required to maintain vehicle heating under different environments determined in the test, and requires a table lookup to determine.

[0065] S10: When all the above conditions are met, the engine controller controls the engine to change the working MAP, so that the engine changes from working in the economic zone to working in the low-efficiency zone, thereby increasing the heat generated by the engine.

[0066] It should be noted that, in some embodiments of the present invention, if one or more of the conditions in the above steps are met, the engine controller can be used to control the engine to change the working MAP, so that the engine changes from working in the economic zone to working in the low-efficiency zone, thereby increasing the heat generated by the engine.
