The application also discloses a vehicle air conditioner control method, which is applied to the vehicle air conditioner system 100 in any one of the above items.

When the information of the temperature adjustment requirement in the cabin 220 is acquired, the main air duct 120 for air (cold air or hot air) generated by the overhead air conditioner 110 is controlled to blow from the air outlet to the cabin 220 through the air outlet 121 or through the air outlet guide duct 133 and the air outlet duct 140 in sequence. When the information of the demand for temperature adjustment in the cabin 220 is acquired, the overhead air conditioner 110 is controlled to generate air (cold air or hot air), the fan 170 and the adjusting member 160 of the air outlet 121 corresponding to the air outlet/guide duct 133 are opened, and the defrosting/guide duct 131 and the adjusting member 160 corresponding to the battery/guide duct 132 are closed, so that the air passes through the air outlet 121 or sequentially passes through the air outlet/guide duct 133 and the air outlet duct 140 from the main duct 120, and is blown to the cabin 220 from the air outlet.

The temperature sensor detects the temperature of the vehicle compartment 220 in real time to obtain a temperature signal so as to know whether a temperature regulation requirement in the vehicle compartment 220 exists.

When the temperature of the cabin 220 is too low, the central controller 190 turns on the overhead air conditioner 110 according to the temperature signal, the overhead air conditioner 110 generates hot air, and meanwhile, the central controller 190 also turns on the fan 170 and the adjusting member 160 of the air outlet 121 corresponding to the air outlet duct 133, and turns off the defrosting air guide duct 131 and the adjusting member 160 corresponding to the battery air guide duct 132, and the hot air is blown to the cabin 220 through the main air duct 120 and the air outlet duct 140 under the action of the fan 170, so as to increase the temperature in the cabin 220. If the temperature is too low in cold weather, the temperature sensor in the automobile chamber 220 detects that the temperature cannot reach the set temperature later, namely, the radiator 180 in the automobile is automatically started, and the heat generated by the running of the automobile can be dissipated to the automobile chamber 220 by the radiator 180 in the automobile, so that the temperature in the automobile chamber 220 is ensured to reach the set value. At this time, the air conditioner hot air and the heat of the radiator 180 in the vehicle come out from the middle part and the bottom of the carriage and are close to the feet of passengers, so that the comfort degree of the passengers is high.

Correspondingly, when the temperature of the cabin 220 is too high, the central controller 190 turns on the overhead air conditioner 110 according to the temperature signal, the overhead air conditioner 110 generates cold air, and meanwhile, the central controller 190 also turns on the fan 170 and the adjusting piece 160 of the air outlet 121 corresponding to the air outlet guide duct 133, and turns off the defrosting guide duct 131 and the adjusting piece 160 corresponding to the battery guide duct 132, and the cold air is blown to the cabin 220 through the main air duct 120 and the air outlet duct 140 under the action of the fan 170, so as to reduce the temperature in the cabin 220.

When the defroster 150 temperature adjustment demand information is acquired, the air (cold air or hot air) generated by the overhead air conditioner 110 is controlled to be blown from the main air duct 120 to the defroster 150 through the defrosting induction duct 131. When the information of the temperature adjustment requirement of the defroster 150 is acquired, the overhead air conditioner 110 is controlled to generate air (cold air or hot air), the fan 170 and the adjusting piece 160 of the air outlet 121 corresponding to the defrosting air guide duct 131 are opened, and the air outlet air guide duct 133 and the adjusting piece 160 corresponding to the battery air guide duct 132 are closed, so that the air is blown from the main air duct 120 to the defroster 150 through the defrosting air guide duct 131.

When the front windshield is fogged in rainy days in summer, the overhead air conditioner 110 starts a refrigeration mode to generate cold air, and meanwhile, the central controller 190 also starts the fan 170 and the adjusting piece 160 of the air outlet 121 corresponding to the defrosting air guide duct 131, closes the air outlet air guide duct 133 and the adjusting piece 160 corresponding to the battery air guide duct 132, and guides the cold air into the defroster 150 to finish the defogging of the front windshield.

When the front windshield glass is frosted in winter, the overhead air conditioner 110 starts a heating mode to generate hot air, meanwhile, the central controller 190 also starts the fan 170 and the adjusting piece 160 of the air outlet 121 corresponding to the defrosting air guide channel 131, closes the air outlet air guide channel 133 and the adjusting piece 160 corresponding to the battery air guide channel 132, introduces the hot air into the defroster 150, and simultaneously the defroster 150 heats itself, and the front windshield is heated by the two heat beams simultaneously, so that the quick defrosting of the front windshield glass is completed.

When the battery temperature adjustment demand information is acquired, the air (cold air or hot air) generated by turning on the overhead air conditioner 110 is controlled to be blown from the main air duct 120 to the battery compartment through the battery draft duct 132. When the information of the battery temperature adjustment requirement is acquired, the overhead air conditioner 110 is turned on to generate air (cold air or hot air), the fan 170 and the adjusting piece 160 of the air outlet 121 corresponding to the battery air guiding duct 132 are also turned on, and the air outlet air guiding duct 133 and the adjusting piece 160 corresponding to the defrosting air guiding duct 131 are turned off, so that the air is blown to the battery compartment from the main air duct 120 through the battery air guiding duct 132 under the action of the fan 170.

The temperature sensor detects the temperature of the battery in real time to obtain a temperature signal so as to know whether the requirement of battery temperature regulation exists.

When the temperature of the battery is too high, the central controller 190 turns on the overhead air conditioner 110 according to the temperature signal, the overhead air conditioner 110 generates cold air, and simultaneously the central controller 190 also turns on the fan 170 and the adjusting piece 160 of the air outlet 121 corresponding to the battery air guiding duct 132, and turns off the air outlet air guiding duct 133 and the adjusting piece 160 corresponding to the defrosting air guiding duct 131, and the cold air enters the battery compartment through the main air duct 120 and the battery air guiding duct 132 under the action of the fan 170, so as to reduce the temperature in the battery compartment. When the temperature in the battery is lower than the preset temperature in the central controller 190, the central controller 190 turns off the fan 170 and the adjusting member 160 of the air outlet 121 corresponding to the overhead air conditioner 110 and the battery air guiding duct 132 according to the real-time temperature signal, thereby completing the automatic cooling of the battery.

When the temperature of the battery is too low, the central controller 190 turns on the overhead air conditioner 110 according to the temperature signal, the overhead air conditioner 110 generates hot air, meanwhile, the central controller 190 also turns on the fan 170 and the adjusting piece 160 of the air outlet 121 corresponding to the battery air guiding duct 132, and turns off the air outlet air guiding duct 133 and the adjusting piece 160 corresponding to the defrosting air guiding duct 131, and the hot air enters the battery compartment through the main air duct 120 and the battery air guiding duct 132 under the action of the fan 170, so as to raise the temperature in the battery compartment. When the temperature in the battery is higher than the preset temperature in the central controller 190, the central controller 190 turns off the fan 170 and the adjusting member 160 of the air outlet 121 corresponding to the overhead air conditioner 110 and the battery air guiding duct 132 according to the real-time temperature signal, thereby completing the automatic temperature rise of the battery.
