摘要
汽车组合仪表能够在汽车行驶过程中实时向驾驶员提供诸如车速、发动机转速、燃油量、发动机冷却液温度、各种危险报警等反映汽车工作状况的各种信息,是驾驶员与车辆进行信息沟通的重要媒介,对安全行车及控制油耗起到了至关重要的作用。本文系统介绍了以飞思卡尔公司的MC9S12DP512为控制核心、基于CAN总线的汽车组合仪表实现方案,并阐述了该系统的硬件电路设计及软件实现。
The automobile combination instrument can provide drivers with speed,engine speed,fuel quantity,the temperature of engine coolant and various danger alarms in real time,which reflect all kinds of information of the operating condition of the car.The instrument is an important medium of communication between the driver and the vehicle,and plays a vital role in safe driving and the control of fuel consumption.This paper will present a systematic introduction to the realization of the instrument which uses the MC9S12DP512 of Freescale as control center and is based on CAN bus.The hardware circuit design and software implementation of the system will also be expounded.
