近年来,汽车电子化和智能化的普及已成为大势所趋,随之而来的是汽车电子控制单元(ECU)的广泛应用。之后ECU的线路也越发复杂,集成度越来越高。为简化线路、降低成本,提高电子系统的安全性和可靠性,汽车上多个ECU之间的信息传递开始采用“控制器局域网”(CAN)技术,使车辆的各个ECU形成一个网络系统。
In recent years, the popularity of automotive electronics and intelligent has become the trend of the times, followed by a wide range of automotive electronic control unit (ECU) applications. After the ECU circuit is also more complicated, more and more integrated. In order to simplify the circuit, reduce the cost and improve the safety and reliability of the electronic system, the information transmission among multiple ECUs in the automobile begins to adopt “CAN” technology to form each ECU in the vehicle into a network system .
