摘　　要：现今倒车雷达在汽车电子领域中得到广泛应用,但其大部分产品仅仅是独立的电气控制单元,无法与车载CAN网络接轨。该文应用MCP2510 CAN控制器和TJA1050 CAN收发器设计一种倒车雷达的CAN总线智能节点。给出倒车雷达的总体硬件结构、CAN总线接口电路以及通讯报文和软件设计,结合插值运算提高报文精度,并通过实验验证了本设计的可行性。使倒车雷达能够被车载网络识别,实现与CAN总线的数据通讯和资源共享。Car reversing radars has been widely used in the field of automotive electronics now.Most of them products only as an independent electrical control unit,and are unable to be connected to the CAN networks of vehicle.A design of CAN-bus intelligent node for car reversing radar is presented in this paper,using a MCP2510 CAN controller and a TJA1050 CAN transceiver.Then,the paper gives the overall hardware architecture of car reversing radar,CAN-bus interface circuit,as well as communication messages and software design,combines with interpolation operation to improve precision of message.And its feasibility is verified by experiments.Car reversing radar can be identified by CAN networks of vehicle,and its data communication and resource sharing with CAN-bus are realized.
