It is described based on the new-energy automotive air-conditioning control system of video sensing technology in use, comprising the following steps：
Step 1, electric automobile car door are opened, and passenger starts to get on the bus/get off；
Step 2, driver press the air conditioner refrigerating button on control panel 12；
Step 3, initial refrigeration mode are opened, and conditioning control unit monitors full car working status；
Step 4, camera 4 detect regional passengers quantity, and (passenger is in car in the region for marking where passenger
Sitting posture, due to 4 installation site of camera and angle reason, it is impossible to obtain the complete limbs of whole passengers, whole can only be obtained
The head zone of occupant, therefore face identification method is used, identification passenger and statistical number of person, camera make 4 to use threshold value diagnostic method
Determine whether to belong to face；As system judges that a certain image belongs to the category of face, then system belongs to judgement the position of face
It is marked, and identifies that the face belongs to region, system differentiates all positions in the region one by one, and calculates the number of face
Amount；)；
Step 5, camera 4 count each region number of occupants, and the information is sent to air-conditioner ECU；
Step 6, air-conditioner ECU adjust different zones compressor electric motor rotating speed according to each zone passenger number.In order to realize pair
The control of compressor, using the control method of duty cycle (PWM).Power relation is used according to region number and air-conditioning, is determined most
