The present invention provides an air conditioner control system for a vehicle, as shown in fig. 1 to 2, comprising: the system comprises a data acquisition module 1, a controller 2, an electrically-driven air-conditioning subsystem 3 and an engine-driven air-conditioning subsystem 4; the electric drive air-conditioning subsystem 3 and the engine drive air-conditioning subsystem 4 are respectively connected with the controller 2; the data acquisition module 1 is used for acquiring the temperature inside the vehicle, the temperature outside the vehicle, the rotating speed of an engine, the wind speed of a condenser, the working state information of the electrically-driven air-conditioning subsystem 3 and the working state information of the engine-driven air-conditioning subsystem 4 and transmitting the information to the controller 2; the controller 2 controls the electric-driven air conditioning subsystem 3 to operate according to the temperature inside the vehicle and the temperature outside the vehicle, the temperature inside the vehicle is adjusted and controlled, and when the temperature inside the vehicle exceeds a threshold value, the controller 2 controls the electric-driven air conditioning subsystem 3 to adjust the temperature inside the vehicle.
It can be understood that the automobile is provided with two-day air conditioning systems, namely a system for refrigerating an engine, and a system for refrigerating and heating the interior of the automobile. Of course, the two systems can share one compressor, and can be respectively provided with two sets of compressor condensers and other equipment.
In order to switch between the two systems, the controller 2 performs switching control, and the switching control may be performed according to the temperature inside the vehicle, the temperature outside the vehicle, and the operating state of the engine.
In the invention, the controller 2 is also used for acquiring the rotating speed and the temperature of the engine in real time when the engine works, controlling the engine to drive the air-conditioning subsystem 4 to be started, driving the air-conditioning subsystem 4 to work when the engine works, and automatically switching to the electrically-driven air-conditioning subsystem 3 to work when the engine is closed.

COP value is a common acronym used in the refrigeration industry for coefficient of performance, called coefficient of performance, defined as COP (cooling capacity (or heating capacity)/energy consumed (which may be electricity, heat, or fuel). Based on the reference to the COP value, the compressor operation state of the system can be controlled according to the COP value states of the two systems.
In the invention, a controller 2 is respectively connected with a data acquisition module 1, an electrically-driven air-conditioning subsystem 3 and an engine-driven air-conditioning subsystem 4 through a CAN bus 5.
