摘要
分析了差动制动的力学特性,并通过ADAMS/CAR建立整车仿真模型,对不同制动初速度下的直线制动及转弯制动进行仿真分析。结果表明,差动制动方式可以减小汽车制动时的侧向位移量;转弯制动时,内轮施加制动力可改善转向不足,外轮施加制动力可改善过度转向;内后轮与外前轮对于制动稳定性影响较大。
The mechanical characteristic of differential braking was analysed. Simulation model of the vehicle was established by ADAMS/CAR, and linear braking and turning braking were analysed under different braking initial velocities. Result shows that differential braking could reduce lateral displacement in braking and applying brake force to the inner wheel could improve the understeering, applying brake force to the outer wheel could improve the oversteering. Inner rear and outer frontal tyres have great effects on braking stability.
