| 摘 要： | 针对实际测得的汽车制动时的轮速信号,分别采用了卡尔曼滤波方法和传统滤波方法进行信号处理。分析表明采用卡尔曼滤波方法处理后的车轮角加速度信号更能真实地反映出汽车ABS系统的工作过程,证明了卡尔曼滤波是一种可用于ABS轮速信号处理的有效手段,因此采用卡尔曼滤波的ABS控制算法可更有效地防止制动时车轮抱死,提高汽车制动时的方向稳定性。

| Abstract: | The measured vehicle wheel speed signal is processed respectively by Kalman filter and tradition filter method.The analysis indicates that the wheel angle acceleration signal processed by Kalman filter can show the operation process of ABS system more really than traditional filter, and proves that the Kalman filtering is an effective means to wheel speed signal processing of ABS system. So that the control algorithm of ABS system with Kalman filter can prevent the wheel lock during braking and improve the direction stability of vehicle brake more effectively. |
