基于MSP430电动车控制系统的设计

Design of the Control System of MSP430 Electric Vehicle

该系统基于MSP430F149单片机为电动车的控制核心。整个电动车智能控制系统包括:主控制模块、电机驱动模块、方向控制与速度检测模块,水平检测传感器模块四大部分。其控制过程是通过对各种传感器采集的数据进行处理和判断,实现电动车在跷跷板上不同路段的行驶方向和速度的实时控制以及在相应的位置达到动态平衡,同时用LCD对各指定路段行驶的时间进行实时显示,采用PWM与霍尔传感器实现了对电动车自动往返速度的精密控制。

In the system, the MSP430F149 is used as the center - controlling unit. It consists of four modules as the following： the main controlling module, the motor driving module, the direction - controlling and speed - testing module, the level - testing sensor module. By making use of the data collected bye various of sensers and using software program to control the direction of the vehicle in different sections of a teeterboard timely. LCD is used to display the time the appointed distance spent. The exact control to the electric vehicle＇s auto - moving has been realized by using PWM technique and Hall sensor.
