摘要
开发了汽车车身低速电器的CAN总线控制系统,从而实现了车身电器的网络化控制。采用飞利浦公司的P87C591通信芯片,阐述了CAN总线的通信协议、汽车低速电器采用SAEJ1939通信协议实现CAN总线通信的设计要点,并分块进行了CAN总线控制系统的硬件设计和软件设计。整个控制系统有效地减少了轿车线束数量,为汽车节省了大量的布线空间。
A CAN bus control system of low speed electrical apparatus of car bodes was developed in this paper,and their network control had been realized.A P87C591 chip of Philips company was introduced in the paper,and a CAN communication protocol was described,as well as the key point of design that realized the CAN communication by used SAEJ1939 communication protocol of low-speed electrical apparatus of vehicles was given.Meantime,the hardware and software of CAN control system had been constructed.The whole control system reduced the number of wire,to save the wiring space effectively.
