一种基于CAN总线的高可靠汽车控制系统的设计与实现

Design and Implementation of one High reliable CAN bus-based Automobile Control System

作者在开发基于CAN总线的汽车仪表控制系统的过程中,进行了多次测试,致力于提高整个系统的可靠性。结果证明合理的电路设计和软件方法不仅可以充分利用CAN协议的可靠性机制,而且能够解决CAN协议中低优先权的帧可能长时间得不到发送的问题,降低电磁辐射,控制噪声信号的干扰,全面提高整个汽车系统的可靠性。

When developing an automobile meter panel control system,the authors aimed at improving reliability of the whole system.A number of experiments indicate that reasonable circuits and software design can fully make use of the reliability of CAN protocol,solve the problem of frame of low priority that may not be transferred on time,suppress electromagnetic emissions,control noise signal interference,greatly improve the reliability of the whole automobile system.
