基于CAN总线技术的车载网络系统设计

Design of In-vehicle Network System Based on CAN Bus Technology

CAN总线技术越来越多地被应用于车载网络系统,以实现信息与资源共享、简化布线、协调控制及提高汽车综合性能等。以TMS320LF2407A作为控制系统芯片,实现SCI与PC机的通信;使用VC++中MFC编写多线程串口通信界面程序,作为车载网络系统的测试、诊断软件;通过CAN总线实现对车身信息的实时检测及对控制部件的实时控制。

CAN bus technology is applied to in-vehicle network system increasingly to share information and resources, simplify wires layout, coordinate control and improve vehicle comprehensive properties. TMS320LF2407A was used as the control system chip to realize serial communication between SCI and PC. Multi-threaded serial communication interface was programmed by MFC in VC ＋＋, which served as the test and diagnosis software. Real-time detection of vehicle information and real-time control on control parts were achieved by CAN bus.
