摘　　要：制动时汽车的方向稳定性是评价汽车制动性能的指标之一。针对电动汽车单轴机电复合制动方向的稳定性问题,建立了在机电复合制动时利用附着系数的数学模型;在Matlab中利用M文件仿真,根据ECE R13制动法规对某电动汽车不同轴下的机电复合制动方向的稳定性进行分析。仿真结果表明:前驱型的电动汽车机电复合制动在制动效率和方向稳定性方面优于后驱型电动汽车。The direction stability is one of indices to evaluate automobile＇s brake performance.A mathematical model of attachment coefficient was built for the direction stability of electric vehicle uniaxial electro-mechanical brake.Mathematical model was simulated on matlab/M file,and analyzed the direction stability of an EV＇ s electro-mechanical brake under different axles according to ECE R13.The simulation results show that the front drive EV is better than the rear drive EV in the respect of braking efficiency and direction stability.
