摘要
针对当前车辆仪表的发展趋势,以CS8190为核心元件设计并实现了一套稳定、精确的电子式车辆转速/里程表。主要介绍了转速表驱动电路和里程计数器电路的设计过程及其工作原理,并对其中的主要元件和参数的选择方法作出了详细的说明。并且通过试验、调试,达到了预期的技术指标和目的。
Aimed at the tendency of the development of vehicle meter, a type of stable and accurate electronic vehicle tachometer/ odometer based on IC CS8190 is designed and realized. What described mostly in the article is the design process and the working principles of the circuit of tachometer driver and mileage counter. And the selection methods of some main elements and parameters are also specified. Moreover, the expected technical targets and purposes are realized through testing and debugging.
