基于CAN总线的汽车组合仪表

Design of Combined Meter in Automobile Based on CAN Bus

本文介绍了CAN总线协议及其基本特点,并给出了一个基于CAN总线的汽车组合仪表的设计方案。该设计将组合仪表作为整个车身CAN网络的一个节点,以从CAN总线上获取汽车信息的方式代替了传统的模拟采样提供信息的方式,从而更好地满足现代汽车电子系统网络一体化控制的需求。

The paper introduces the conception and the basic feature of CAN, And presents a design option that is about Combined Meter in Automobile which based on CAN bus. In the design, the meter is a node of the CAN network, according to the BUS of CAN ,it gains the information of automobile which replaces the custom analog sample providing information method, and adapts the need of modem automobile electronic system in network integrative control.
