Calculation for Speed of Braking Vehicle with ABS

汽车ABS系统中 ,滑移率是主要控制参数 ,制动时车速是确定车轮滑移率的基础 .通过轮胎制动模型 ,对于有稳定压力源ABS的系统 ,在结构和调压方式确定时 ,能建立制动轮缸的等效压力函数 。

The speed of the vehicle's abrupt deceleration is a key factor in determining the slip ratio, which is a fundamental control parameter in anti_lock brake system. With regard to the ABS with a stable pressure source in the brake system, the equivalent pressure function of the brake cylinder can be set up in the braked_wheel model when the structure and the pressure regulation model of the cylinder is determined. Therefore, the average vehicle deceleration and speed can be calculated by measuring the braked force on the wheel from the earth and the vehicle kinematics equation.
