摘要
汽车紧急制动时,制动力矩、制动减速度、车速、车体俯倾角及其角加速度与时间呈非线性关系。本文对BJ212轻型越野汽车满载紧急制动进行了试验,以试验结果为依据,讨论了汽车紧急制动时诸参数之间的关系。其结论是:在瞬变过程中,制动减速度及车体俯倾角加速度与其制动初速度无关;在平稳过程中,制动减速度及车体俯倾角加速度随制动初速度增大而减小,而且大致成线性关系。
A BJ212 Jeep has been tested under full load and emergency braking. Based on the tested results, the relations of various parameters of motor vehicle in emergency braking are discussed in this paper. It is concluded that in transient state the braking deceleration and pitching acceleration have no connection with the initial speed, while in steady state the deceleration and pitching acceleration decrease with the increase of the initial speed and approximately presents a linear variation.
