Design and Research on Air Conditioning Control Network of Electric Vehicle Based on CAN-Bus

The design of the electric air-conditioning CANbus communication system makes a target of electric vehicles in order to form digital control network of a number of electronic control unit in electric vehicles, develop electric vehicles CAN (Controller Area Network)bus system, adopting communication protocol SAE J1939;the use of microprocessor STC12C5A60S2 complete design of CAN bus interface circuit; The digital simulation of virtual bus is realized by hardware, then the system was equipped a car with to test its Performance. Test results show that the system works stable, has strong anti-jamming ability, and can meet the real-time communication and integrated control requirements.
