基于CAN总线的车辆模式开关设计

The Vehicle Mode Selection Switch Design Based on CAN Bus

介绍车辆模式开关的基本应用,采用CAN总线的方式实现了车辆模式的选择。利用总线仿真工具模拟实现车辆其它CAN网络模块与车辆模式开关的信息交互。结果表明车辆模式开关能够有效地将车辆模式的请求信号发布到CAN网络上,同时也能有效地接收其它网络节点的指令,并做出响应。车身开关的集成化设计是汽车电子领域的必然趋势,因此基于CAN总线的车辆模式开关设计具有一定的工程应用价值。

The basic application of vehicle mode switch is introduced and the choice of vehicle mode is realized by CAN bus.The information interaction between other CAN network modules and the vehicle mode switches is simulated by using the bus simulation tool.The results show that the vehicle mode switch can effectively send the request signal of the vehicle mode to the CAN network and receive the instructions from other network nodes,responding accordingly.The integrated design of the car body switch is an inevitable trend in the field of automotive electronics.Therefore,the design of the vehicle mode switch based on CAN bus has certain engineering application value.
