The invention provides a vehicle driving parameter estimation method, a vehicle control method and a related device, and relates to the technical field of vehicles. According to the method, the wheel speed and the wheel dynamic characteristic parameters of the vehicle are obtained, yaw angle correction processing and/or slip rate correction processing are/is carried out on the wheel speed, the centroid speed of the wheel is obtained, the wheel speed confidence degree of the wheel is determined according to the wheel speed and the wheel dynamic characteristic parameters, the accuracy of judging the wheel speed confidence degree is improved, and the accuracy of judging the wheel speed confidence degree is improved. Furthermore, the reference vehicle speed of the vehicle is estimated according to the centroid speed and the wheel speed confidence coefficient, and the accuracy of the estimated reference vehicle speed is improved.

    本申请提供一种车辆行驶参数的估算方法、车辆控制方法及相关装置,涉及车辆技术领域。该方法通过获取车辆的轮速和车轮动力学特征参数,对轮速进行横摆角度修正处理和/或滑移率修正处理,得到车轮的质心速度,并根据轮速和车轮动力学特征参数,确定车轮的轮速置信度,提高对轮速置信度判断的准确性,进一步根据质心速度和轮速置信度,估算得到车辆的参考车速,提高估算得到的参考车速的精确性。
