摘要
汽车紧急制动时,制动力矩、制动减速度、车速与时间都呈非线性关系。本文对BJ212越野车,满载时紧急制动做了多次试验。以试验结果为基础,讨论了汽车在紧急制动时各种参数之间的关系。其结论是:在瞬变过程中,减速度与制动初速无关;在平稳过程中,减速度随制动初速度增大而减小,且大致成线性关系。
When a motor vehicle is emergently braked, its brake torque, braking deceleration,brake speed and time present nonlinear variations. A model BJ 2l2 Jeep has been tested several times under full load and in emergency brake application. On the basis of the tested results,the relations of various parameters of motor vehicle in emergency brake appIication are discussed in this paper. It is concluded that in transient state the braking deceleration has nothing to do with the brake initial speed,while in steady state the deceleration decreases along with the increase of the brake initial speed and approximately presents a linear variation.
