基于车载CAN总线的倒车雷达单元设计

摘要

倒车雷达在汽车中得到广泛应用,但没有与车载CAN总线网络相联系,造成其功能不完善.用PIC18F258单片机设计一个倒车雷达单元,使倒车雷达能够被车载网络识别,实现与CAN总线的数据通信与资源共享,完成倒车雷达的自动刹车功能.%Parking sensor has been widely used in car, whose function is not perfect since it dose not link with CAN-bus network of car. A parking sensor unit was designed with PIC18F258 microcontroller, for which the parking sensor can be identified by CAN-bus network to achieve data communication and resources sharing,so as to complete the automatic braking function of reversing radar..
