摘　　要：为了使汽车在上、下坡制动时前后制动力分配能够满足ECE法规的要求。通过对汽车在上、下坡制动时进行受力分析,得到汽车上、下坡制动时前、后轴的利用附着系数,根据ECE法规和汽车在上、下坡及平直路面上制动时前、后轴利用附着系数的大小关系进行前、后制动力分配系数设计,最后对分配效果进行验证,结果表明:该方法设计的制动力分配系数在汽车上、下坡制动时可以满足ECE法规的要求。To make sure the front and back braking force distribution can meet the requirements of ECEregulations when the vehicle brakes uphill and downhill, the front and rear axle utilization adhesion co-efficient of the vehicle were obtained by force analysis during braking uphill and downhill, then thebraking force distribution coefficients were designed according to ECE regulations and the magnituderelation of the front and rear axle utilization adhesion coefficients during braking uphill, downhill andstraight, finally distribution effects were verified. The results show the braking force distribution coeffi-cients designed by this method can meet the requirements of ECE regulations when the vehicle brakesuphill and downhill.
