【摘要】 采用计算机仿真方法实现了对汽车ABS制动过程的模拟仿真,开发了一套ABS性能评价系统。该系统具有图形与数字显示功能,能直观地反映汽车ABS性能,可以迅速地显示车辆参数和道路参数对ABS性能的影响。在基于计算机仿真的基础上提出了反映ABS性能的7大评价指标:附着系数利用率、附着系数利用率均方差、滑移率均值、滑移率均方差、稳定系数、制动压力均值、制动压力均方差,综合利用这些指标可以较好的评价计算机仿真下的汽车ABS的基本性能。更多还原

【Abstract】 In this paper, computer simulation is applied to evaluating the performance of automobile ABS (anti-lock braking system). An evaluation system of ABS performance is developed. The system has the functions of diagram and digital displaying. It can reflect the performance of ABS clearly, and can quickly display the effect on ABS performance. Seven evaluation indexes are brought forward based on the simulation including the friction coefficient utilization rate, the variance of friction coefficient utilization rate, the mean of slip values, the variance of slip values, the stability coefficient, the mean of braking pressure and the variance of braking pressure. To combine these indexes can better evaluate the performance of ABS.更多还原
