ABS系统车轮角加速度计算方法研究

Study on Calculation Method of Angular Acceleration of Wheel in ABS System

实现基于逻辑门限值控制的汽车防抱制动系统(ABS)的关键技术之一是车轮角加速度的准确计算。利用车轮角速度信号,应用卡尔曼滤波技术来计算车轮角加速度信号。试验结果验证了该方法的可行性和有效性。

The precondition of realizing logic thresholds based anti-lock braking system(ABS)is the accuracy calculation of wheel angular acceleration.Utilizing the wheel speed signals and applying the Kalman filter technology,the wheel angular acceleration is calculated.The trial results verify the feasibility and validity of this method.
