摘　　要：通过CATIA软件进行实体建模获得整车的质心坐标,使用MATLAB软件分析了不同动力电池布置方案对电动公交客车制动力分配系数的要求,进而分析、比较了采用两种不同布置方案的电动公交客车的制动效能。分析表明在城市道路上行驶的电动公交客车采用方案2优于方案1。同时对整车质心的位置对客车制动效能的影响进行了分析,获得了整车质心到前轴距离以及质心高度的允许范围,为动力电池布置提供一定的参考依据。Vehicle centroid coordinates were got by established model through software of CATIA,the brake force distribution coefficient＇s requirements were analyzed by MATLAB software under two different power battery layout programs,then,braking efficient performance of the two different programs was analyzed and compared.Results showed that the program 2 was better than the program 1 when the bus driven on urban road.Meanwhile the effect of vehicle centroid position on braking efficient was analyzed,and the allowed distance of vehicle centroid to front axle and centroid height were got,which provides reference for power battery layout.
