摘　　要：针对前轮驱动型电动汽车,为提高电动汽车能量再生利用,根据电机发电能量、车辆行驶速度、电池充电特性及ECE制动法规相关要求,提出了一种前、后轮制动力分配控制策略,建立了控制策略数学模型。结合典型城市循环工况,利用电动汽车仿真软件Advisor2002对制动力控制策略进行仿真分析。结果表明,提出的控制策略在保证安全制动的前提下,制动能量回收效果优于Advisor中原有的控制策略,制动能量回收效率显著提高,具有较强的制动能量回收能力,可以有效延长电动汽车的续驶里程。To study the front-wheel drive electric vehicle, a braking force distribution control strategy was pro- posed, which was used in the braking force proportion of front and rear wheels. The strategy was proposed on the basis of motor power generation characteristics, vehicle speed, battery charging characteristics and relative ECE regulations. The mathematical model of control strategy was established. The simulation of control strategy for braking force distri- bution was carried out on the typical urban driving cycle with the electric vehicles simulation software Advisor2002. The simulation results show that on the premise of braking safety, this control strategy has a better effect of braking energy recovery than original control strategy of Advisor, which can enhance the efficiency of braking energy recovery and the driving range of electric vehicle significantly.
