基于CAN的客车车灯控制及其状态自动检测方法

Method for Passenger Car Lamp Control and Status Automation Test Based on CAN

传统客车车灯控制与状态检测方法给客车驾驶带来安全隐患.文中采用车载网络技术构建了基于CAN的客车车灯控制系统,确定了系统节点以及与CAN相关的系统参数.在新的车灯控制方式下,设计了基于CAN的客车车灯控制与状态自动检测硬件电路,并在程序设计中采用双字节判断法对车灯状态进行判断和指示.

It will bring danger for passenger car to use traditional lamp control and status test method. This paper constructs passenger car lamp control system with in-vehicle network technology, designs system nodes and system parameters related with CAN（Controller Area Network）. Under the new passenger car lamp control method, passenger car lamp control and status automation test hardware circuit are designed based on CAN. Double bytes judgment method to indicate passenger car lamp status is utilized in program design. This method can provide reference for control and status test of other on off electronic units under vehicle network control mode.
