摘要
纯电动汽车的控制系统任务多,如前进、倒车、制动、制动能量回收等,而且因汽车的安全性直接关系到乘坐人员的生命安全,所以对实时性和稳定性要求非常高。根据纯电动汽车控制系统的特点和DSP2407内部的丰富资源,如AD模块、CAN总线、看门狗等和实时操作系统UC/OS-Ⅱ出色的稳定性,本文开发出基于DSP2407和实时操作系统UC/OS-Ⅱ的纯电动汽车多任务控制系统。
There are more tasks such as forward, backward, braking, braking energy recovery and so on in the pure electrical vehicle control system. At the same time, the control system requires a high stability and realtime ability because the safety of the vehicle is directly related with rider＇s safety. According to the above characteristics and the DSP2407 rich internal source, just like AD modle, CAN bus and watch dog, the authors choose UC/OS-Ⅱ realtime system for its stability to develop a multi-task control system for the pure electrical vehicle based on the DSP2407.
