[0040] Figure 1 This is a flowchart of a vehicle air conditioning control method according to an embodiment of the present invention. The method is applied to a vehicle and includes the following steps:

[0041] In step S101, in response to the vehicle's air conditioning being turned on, the ambient temperature, the user-set temperature, the vehicle interior temperature, and the sunlight intensity are obtained.

[0042] Step S102: Determine the judgment conditions based on the ambient temperature, the user-set temperature, the vehicle interior temperature, and the sunlight intensity.

[0043] Step S103: Compare the judgment condition with the preset condition to obtain the comparison result.

[0044] In step S104, in response to the comparison result indicating that the judgment condition meets the preset condition, the engine output power of the vehicle is increased to increase the engine heat generation.

[0045] In this embodiment of the invention, in response to the vehicle's air conditioning being turned on, the ambient temperature, the user-set temperature, the vehicle interior temperature, and the sunlight intensity are acquired; based on these factors, a judgment condition is determined; the judgment condition is compared with a preset condition to obtain a comparison result; in response to the comparison result indicating that the judgment condition meets the preset condition, the vehicle's engine output power is increased to increase engine heat generation. Through this method, when the air conditioning's heating capacity is insufficient (i.e., the judgment condition meets the preset condition), the insufficient heating capacity of the air conditioning can be compensated by increasing the vehicle's engine output power to increase engine heat generation. This allows for direct heating through the engine, eliminating the need for an additional, higher-power PTC heater. This solves the technical problem of insufficient heat generated by the vehicle engine during winter heating, which previously required a high-power PTC heater to improve heating efficiency and increased vehicle weight, thus reducing operating costs.

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

[0047] Optionally, the judgment conditions are determined based on the ambient temperature, the user-set temperature, the vehicle interior temperature, and the sunlight intensity, including: determining the target air outlet temperature using a preset formula based on the ambient temperature, the user-set temperature, the vehicle interior temperature, and the sunlight intensity; determining the difference between the target air outlet temperature and the ambient temperature as the judgment condition; and comparing the judgment condition with the preset conditions 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 further includes: obtaining the position of the temperature damper of the vehicle air conditioning; determining the position of the temperature damper 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 further 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 further includes: acquiring the vehicle's engine coolant temperature; using the engine coolant temperature as a judgment condition; comparing the judgment condition with preset conditions to obtain a comparison result, including: comparing the engine coolant temperature with a preset coolant temperature threshold to obtain a comparison result.

[0051] Optionally, the vehicle air conditioning control method further includes: obtaining the average output power of the engine during the current stage of the vehicle's calculation cycle; 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 increased to increase engine heat generation, including: in response to the comparison result indicating that the judgment condition meets the preset condition, the engine is controlled to switch from operating in the economic zone to operating in the inefficient zone to increase engine heat generation.

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

[0054] Reference Figure 3 After the air conditioner is turned on, the air conditioner controller performs calculations based on the ambient temperature, the interior temperature, the user-set temperature, the sunlight intensity, the set air volume, the engine coolant temperature, and the position of the air damper. It then controls the temperature damper motor to operate to the corresponding position and outputs a heating boost request to the engine controller based on the calculation results. The engine controller calculates the engine output power based on the engine torque and engine speed and adjusts the engine operating MAP as needed.

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

[0056] S1: Turn on the air conditioner.

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

[0058] S3: Determine if the ambient temperature is below the threshold (first preset temperature): The amount of heat required for heating varies in different vehicles. The minimum ambient temperature that the vehicle heating system can maintain to ensure comfort inside the vehicle needs to be determined through testing, and this will be used as the judgment threshold.

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

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

[0061] S6: Determine whether the air conditioner air volume is greater than the threshold (preset air volume threshold). Set the threshold based on the heat demand of the air conditioner under different air volumes obtained from simulation calculations or experimental verification. This threshold is different under different operating conditions and needs to be determined by referring to a table.

[0062] S7: Is the engine coolant temperature lower than the threshold (preset coolant temperature threshold)? This threshold corresponds to the target air outlet temperature calculated in step S2, and it also needs to be determined by referring to a table.

[0063] S8: The air conditioning controller judges and outputs a heating boost request signal to the engine controller. This is executed if the judgments in steps S3, S4, S6, and S7 are all satisfied. To avoid the output signal fluctuations affecting engine operation, the output signal is checked and output in a fixed cycle (e.g., 30 seconds).

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

[0065] S10: When all the above conditions are met, the engine controller controls the engine to change the operating MAP, and the engine changes from operating in the economic zone to operating in the inefficient zone, increasing the heat generated by the engine.

[0066] It should be noted that, in some embodiments of the present invention, the engine can be controlled by the engine controller to change the operating MAP when one or more of the conditions in the above steps are met, so that the engine changes from operating in the economic zone to operating in the inefficient zone, thereby increasing the heat generated by the engine.

Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.
