It is easy to note that by analyzing the collected environmental conditions, the function mode that the vehicle air conditioner needs to enter can be obtained, and then the corresponding actuator of the function mode is controlled to execute the corresponding instruction to control the vehicle air conditioner automatically. This realizes the purpose of automatic control of the air conditioner in the whole process without manual operation, and solves the technical problem that the existing automatic air conditioner mode cannot fully meet the needs of users in different driving scenarios. In this way, the technical effect of automatically adjusting the vehicle air conditioner is achieved, and the needs of users in different driving scenarios are met.

If yes, the refrigeration mode is entered. If no, S306 is executed.

When the target function mode of the vehicle's air conditioning is heating mode, the heater outlet water temperature is adjusted to the target outlet water temperature to regulate the interior temperature of the driver's cab. The calculation method for the target outlet water temperature includes: obtaining the feedforward outlet water temperature of the heater by looking up a table based on the difference between the preset interior temperature and the ambient temperature; correcting the difference between the preset interior temperature and the ambient temperature to obtain the feedback outlet water temperature of the heater; and calculating the sum of the feedforward outlet water temperature and the feedback outlet water temperature to obtain the target outlet water temperature of the heater.

[0108] Specifically, when the vehicle's air conditioning target mode is cooling mode, the interior temperature of the driver's cabin can be regulated by adjusting the compressor speed to the target speed. The calculation process for the compressor target speed can be found in [reference needed]. FIG. 7 .

[0109] FIG. 7 The diagram shown is a flowchart of the calculation process for the target speed of a compressor according to an embodiment of this application. FIG. 7 As shown, the calculation of the compressor target speed includes the following steps: S701 collects ambient temperature, indoor temperature, and preset indoor temperature; S702, calculate the difference between the ambient temperature and the preset indoor temperature, and simultaneously calculate the difference between the indoor temperature and the preset indoor temperature; S703: Based on the difference between the ambient temperature and the preset indoor temperature, the feedforward speed of the compressor is obtained by looking up a table and a boundary limit is set; the difference between the indoor temperature and the preset indoor temperature is corrected to obtain the feedback speed of the compressor and a boundary limit is set. That is, by looking up the difference between the ambient temperature and the preset indoor temperature in a one-dimensional linear difference table, the compressor feedforward speed is obtained (the general rule is that the greater the difference between the ambient temperature and the set temperature, the greater the compressor feedforward speed).

[0110] Simultaneously, the compressor feedback speed is obtained from the difference between the indoor temperature and the preset indoor temperature using a PID (proportional-integral-derivative) algorithm, and upper and lower boundary limits are set for the compressor feedback speed (which can be calibrated, such as -4000rpm~4000rpm).

[0111] S704, the sum of the feedforward speed and the feedback speed is calculated to obtain the compressor pre-speed, and the boundary limit value is performed; That is, the sum of the compressor feedforward speed and the compressor feedback speed is obtained to obtain the compressor pre-speed, and the upper and lower boundary limit values (which can be calibrated, such as 0 rpm~8000 rpm) of the compressor pre-speed are performed.

[0112] S705, the evaporation temperature is collected; S706, the compressor speed correction coefficient is calculated from the evaporation temperature; S707, the product of the compressor pre-speed and the correction coefficient is calculated to obtain the target speed of the compressor.

[0113] It should be noted that the above correction coefficient is obtained according to the evaporator temperature. The correction coefficient calculation method includes: When the evaporator temperature is greater than or equal to 6℃, the correction coefficient is 1 (the first correction coefficient, which can be calibrated, but needs to be less than or equal to 1), when the evaporator temperature is less than 6℃ and greater than or equal to 5℃, the correction coefficient is 0.9 (the second correction coefficient, which can be calibrated), when the evaporator temperature is less than 5℃ and greater than or equal to 4℃, the correction coefficient is 0.8 (the third correction coefficient, which can be calibrated), when the evaporator temperature is less than 4℃ and greater than or equal to 3℃, the correction coefficient is 0.7 (the fourth correction coefficient, which can be calibrated), when the evaporator temperature is less than 3℃ and greater than or equal to 2℃, the correction coefficient is 0.6 (the fifth correction coefficient, which can be calibrated), when the evaporator temperature is less than 2℃, the correction coefficient is 0.5 (the sixth correction coefficient, which can be calibrated). Among them, the first correction coefficient> The second correction coefficient> The third correction coefficient> The fourth correction coefficient> The fifth correction coefficient> The sixth correction coefficient.

[0114] In addition, when the target function mode of the vehicle air conditioner is the heating mode, the indoor temperature of the cab can be adjusted by adjusting the heater outlet water temperature to the target outlet water temperature. The calculation process of the target outlet water temperature of the heater can refer to FIG. 8 .

[0115] FIG. 8 The calculation process of the target outlet water temperature of the heater provided by an embodiment of the application is shown in the flowchart as FIG. 8 The calculation of the target outlet water temperature of the heater includes the following steps: S801, collect the ambient temperature, indoor temperature, and preset indoor temperature; S802, calculate the difference between the preset indoor temperature and the ambient temperature; calculate the difference between the preset indoor temperature and the indoor temperature; S803, according to the difference between the preset indoor temperature and the ambient temperature, the heater's feedforward outlet water temperature is obtained by table lookup, and the boundary limit value is carried out; the difference between the preset indoor temperature and the indoor temperature is corrected to obtain the heater's feedback outlet water temperature, and the boundary limit value is carried out; That is, according to the difference between the preset indoor temperature and the ambient temperature, the heater's feedforward outlet water temperature is obtained by one-dimensional linear difference table (the greater the difference between the set temperature and the ambient temperature, the higher the heater's feedforward outlet water temperature.

[0116] At the same time, the heater's feedback outlet water temperature is obtained according to the PID algorithm based on the difference between the preset indoor temperature and the indoor temperature, and the upper and lower boundary limit values of the heater's feedback outlet water temperature are carried out (which can be calibrated, such as-40℃~40℃).

[0117] S804, the sum of the feedforward outlet water temperature and the feedback outlet water temperature is calculated to obtain the heater's outlet water temperature, and the boundary limit value is carried out.

[0118] That is, the heater's feedforward outlet water temperature and the heater's feedback outlet water temperature are added to obtain the heater's target outlet water temperature, and the upper and lower boundary limit values of the heater's target outlet water temperature are carried out (which can be calibrated, such as 0℃~80℃).

[0119] It should be noted that the above correction strategy for the evaporating temperature to the air volume gear and the compressor speed is an evaporating protection measure to prevent the evaporating temperature from being too low or even the evaporator from frosting due to the relatively large refrigerating capacity and the relatively small air volume gear.
