Development of CAN Network for VMS Based on XC164CS

In the design of modern vehicles, CAN-bus network has been applied for the information exchange among the ECUs of the vehicle. The CAN communication network for vehicle management system (VMS) is designed based on XC164CS microcontroller in the paper. The characteristics and construction of Twin CAN module of XC164CS were introduced. The principle of time triggered controller area network (TTCAN) is described. The hardware interface circuit is developed to increase the stability and safety of the CAN nodes. The drive software and multitask application is realized on the platform of embedded operation system μC/OS-II. This CAN bus network can improve the anti-jamming and dependability effectively, which was applied to control and exchange the information of the vehicles.
