Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Fig. 1 is the flow chart of the control method of on-board air conditioner according to an embodiment of the invention.
As shown in figure 1, the control method of on-board air conditioner according to an embodiment of the invention, comprises the following steps：
Step S101, the terminal voltage of air blower is determined according to user's selection air quantity gear.
It is understood that in an embodiment of the present invention, different voltages can be corresponded to according to each shelves air quantity of air blower and are made
For the input signal of air door motor such as stepper motor, so as to avoid blower fan in different air quantity, air door motor
Load it is different, cause air door motor step-out or the risk of stall be present
Step S102, the frequency range of air door drive signal is determined according to the terminal voltage of air blower, wherein, the end of air blower
Voltage is bigger, and the frequency range of air door drive signal is smaller.
That is, the impulse generator frequency of controller is controlled according to the terminal voltage of air blower, for example, being in terminal voltage
During 9.2V, the frequency range of air door drive signal can be 4-50Hz, when terminal voltage is 12V, the frequency of air door drive signal
4-25Hz is may range from, can be configured according to actual conditions, be not specifically limited herein.
Step S103, air door motor is controlled according to the air door drive signal of determination, with opening for damper
Spend to target aperture.
Specifically, frequency can be adjusted in real time with voltage pulsation, and frequency is low when voltage is high, and air door motor is defeated

More than anion generator J1-25 voltage DC 4V during sub- normal use starts, if anion generator occurs abnormal, J1-
25 voltages are below DC 2V.Further, anion generator is receiving ON/OFF or AQS (Air Quality
Standard, air quality standard) after oxycarbide value signal, start negative ion generating function, wherein, enter in J1-23J1-24
Enter ion mode, when AQS oxycarbides value is the first predetermined threshold value less than Low threshold, disconnects J1-24 signals and saved with entering
Cleaning mode, enter ion mode when AQS oxycarbides value is the second predetermined threshold value higher than high threshold, when AQS oxycarbides
When value is higher than Low threshold and is less than high threshold (for example, cleaning mode 13min-ion mode 17min) is pressed into automatic mode
Setting time automatic conversion.It should be noted that the first predetermined threshold value, the second predetermined threshold value and default switching frequency can roots
It is configured according to actual conditions.
