车辆变速电控系统ECU和显示器之间CAN总线通信设计

Design of CAN Communication System Used in the Electronic Controller Unit and the LED display

用CAN总线取代传统的变速电控系统的ECU和显示器之间的硬件连接和数据通信 ,同时为电控系统的其它可能部分采用CAN总线连接打下基础。通过仿真环境下对ECU和显示器之间的CAN总线通信的调试 ,及其硬件、软件设计的详细分析 ,得出了CAN总线技术移植到军用车辆上具有可行性的结论。

The work is to investigate the connection and communication between the electronic controller unirt of auto-transmission control system of the vehicles and the LED displayer,with CAN bus not with the traditional cable.In the emulation mode,the software of the communication between the ECU and the displayer is debugged.And also the hardware and software are introduced fully.The experimentation proves that the application of the CAN bus in the electronic controller unit of auto-transmission control system of the vehicles is feasible.
