汽车制动防抱死控制信号分析及门值的选取

用车轮角减速度作为汽车制动防抱系统的临界控制信号，其门值会随着制动工况而改变．本文通过建立数学模型计算制动时车轮的角减速度及其门值，并分析了各种因素变化对它的影响．通过这种方法可以对某种车型在一定的制动工况范围内选取最佳的制动防抱临界控制信号。从而提高汽车的制动防抱效果

Motor ABS Signal Analyses and Choice for the Critical

Using wheel angular deceleration as a critical control signal for ABS, its critical varies with different work conditions. In this paper, a mathematical model has been developed to calculate the wheel angular deceleration of motors in braking, and the influences are analysed. By using this method, an optical control signal for ABS can be chosen so as to raise the effect of ABS.
