Research on Fault Diagnostic System in CVT Based on UDS:

摘要

A communication model of diagnostic network and implementation of unified diagnostic services (UDS) based on controller area network (CAN) bus are presented in this paper, and fault diagnostic function of transmission control unit (TCU), USB- (universal serial bus-) CAN hardware and software modules, and fault diagnostic software based on personal computer (PC) are designed. Model diagnostic method is applied on ratio control, and fault diagnostic system is tested in vehicle.
