Abstract
The study of the applications of CAN bus in the CVT controlling system.To avoid the unnecessary waste which may be caused when the popular high-layer protocol,e.g.CANopen、DeviceNet、SAE J1939、SDS applied in CAN network with few knobs,the eCAN module was analyzed,a simple,reliable and practical high-layer CAN communication protocol was developed and the relevant hardware software was designed.Moreover,the communication between CVT controlling unit and other ECUs was realized.The study of the protocol lays the foundation of the communications between ECUs in car's CAN network.
