摘　　要：从汽车制动性出发,通过对汽车下坡制动功能转换的分析,提出从汽车制动功能角度来考虑下坡纵断面设计极限值的计算模型和试验方法,通过对汽车在下坡转弯处制动的力学分析,提出从计算制动侧滑值的角度来计算下坡平曲线处的极限值,可供同行参考。In view of the vehicle braking performance,the computation model and test method of limiting value of downgrade vertical section design are proposed from the aspect of vehicle braking function through analyzing the function transformation of vehicle braking at downgrade.It is proposed that to calculate the limiting value at curve of downgrade from the aspect of calculating the sideslip value of braking through the mechanical analysis of vehicle braking at turning of downgrade.The research fruit can be consulted by peers.

关 键 词：最大纵坡 坡长限制 汽车制动性 最小圆曲线半径
