摘　　要：借助液压助力系统实现城市电动公交车制动能量回收和起步助力。在分析再生制动模式的基础上,使用模糊控制研究控制规律,兼顾安全性和能量回收效率,考虑车速和制动强度这两个因素研究得出了附加再生制动力系数的规律。对在制动初速为30km/h时再生制动和机械摩擦制动的功率和能量进行了仿真,得到了附加再生制动力后的前后制动力的关系,在不同附着系数路面上制动时均能防止后轮先抱死。结果表明在对原车制动系统改动较小的前提下获得较好的能量回收效率。With the help of hydraulic power system the electric urban bus realizes the function of braking energy recovery and starting power. Based on the analysis of the regenerative braking mode, the fuzzy control is used to study the control law by taking into account the safety and efficiency of energy recovery. The law of additional regenerative braking coefficient is studied about speed and braking intensity. On the brake muzzle velocity of 30kin/h, the braking power and energy of the regenerative braking and mechanical friction braking is simulated. The relationships of the front and rear braking force applied additional regenerative braking force is obtained. It realizes prevent wheel lock on different friction coefficient road suoCace when braking.The results show that a better efficiency is obtained on the premise of small changes of the original brake system.
