The invention discloses a wheel speed effectiveness judgment method and device, equipment and a medium, and relates to the technical field of intelligent auxiliary driving, and the method comprises the steps: carrying out the mean filtering of the current wheel speed of each wheel of a vehicle collected by a wheel speed sensor, so as to obtain the filtered rear wheel speed of each wheel; transferring the filtered rear wheel speed of each wheel to the center of a rear axle of the vehicle to obtain a transferred rear wheel speed corresponding to each wheel; a wheel speed deviation between each of the transferred rear wheel speeds is determined, and a validity of each of the transferred rear wheel speeds is determined based on the wheel speed deviation. According to the invention, the average filtering reduces the influence of the measurement error of the wheel speed sensor on the wheel speed, and the effectiveness of each transfer rear wheel speed is realized through the wheel speed deviation between the transfer rear wheel speeds at the center of the rear axle, so that whether the wheel speed is effective or not can be judged, and the detection accuracy of the wheel speed is improved.

    本申请公开了一种轮速有效性判断方法、装置、设备及介质,涉及智能辅助驾驶技术领域,包括:对轮速传感器采集到的车辆各车轮的当前轮速进行均值滤波,以得到各所述车轮的滤波后轮速;将各所述车轮的所述滤波后轮速转移至所述车辆的后轴中心处,以得到各所述车轮对应的转移后轮速;确定各所述转移后轮速之间的轮速偏差,并基于所述轮速偏差确定每一所述转移后轮速的有效性。本申请均值滤波降低轮速传感器自身存在的测量误差对轮速造成的影响,并通过后轴中心处的各所述转移后轮速之间的轮速偏差每一所述转移后轮速的有效性,能够判断轮速是否有效,也有利于提高轮速检测准确性。
