摘　　要：笔者以Freescale的S08系列8位微处理器MC9S08SL8为核心,为某电动汽车设计了一款仪表盘信号转换器,实现了电机转速检测、与电机控制器的LIN通信、原车仪表信号模拟等功能。利用芯片内部资源特性设计了其硬件结构及电路,根据仪表盘的原理和工作方式设计了软件流程,装车试验运行稳定,有很高的实用价值。Design a dashboard signal convertor for an electric vehicle with Freescale’s S08 series 8-bit microprocessor MC9S08SL8, through the analysis of the original car dashboard interface circuit and principle, use the original car dashboard ＋ the signal converter achieved electric car’s speedometer, ammeter and voltmeter, reduce the difficulty and cost of development of new dashboard. The signal convertor achieved motor speed detection, LIN communication with motor controller,original dashboard sensor simulate and other functions. Design the hardware architecture and circuit based on characteristics of the chip internal resources, and design software process according to the principles and working methods of the dashboard.It has steady performance in the real vehicle test,with high practical value.
