摘要
研究电动自行车用无刷直流电动机辅助功能控制系统,提出如何利用脉宽调制PWM和综合译码控制来实现电动自行车无刷直流电动机的电子刹车、欠压保护、过加速防抖动、堵转保护、巡航及1∶1助力等辅助功能。实车试验表明该系统能有效地改善电动自行车的舒适性、安全性。
The auxiliary functions control system of brushless DC motor for electric bicycle is introduced. An auxiliary functions control system is designed with electric braking, under- voltage protection, over- accelerate vibration avoidance, blocking protection, cruise, 1 ： 1 assistance functions. In the system, the speed control handgrip, brake bolt and the rotor - position sensors are used. The experiment results show that this system can improve the comfort and safety of the E- bicycle.
