基于单片机MC68HC908的座椅后视镜电控系统的设计

Design on the Electronic Control System of Car Seats and Back Mirror Based on MC68HC908

本设计以MC68HC908单片机作为控制器,分别控制继电器和桥式电路驱动电机运动,从而控制汽车座椅和后视镜的运动,达到电动调节座椅和后视镜的目的。本文重点介绍了座椅以及后视镜电动系统的工作原理并给出了相关电路的设计。

This design adopted MC68HC908 single -chip as the controller, to control the relay and the motor driver bridge circuit separately, so as to control the motion of the car seats and the back mirrors. This article focuses on the principle of the electronic system and presents schemas of corresponding circuits.
