The invention provides a vehicle adhesion coefficient obtaining method and device, a vehicle and a storage medium, and relates to the technical field of vehicles, and the method comprises the steps: for each wheel of the vehicle, calculating the slip rate of the wheel according to the obtained vehicle speed and the wheel speed of the wheel, and calculating the utilization adhesion coefficient of the wheel according to the driving force of the wheel and the vertical load of the wheel, and determining the adhesion coefficient of the wheel according to the utilization adhesion coefficient of the wheel and the slip rate of the wheel. According to the technical scheme, for each wheel of the vehicle, the utilization adhesion coefficient of the wheel is corrected based on the slip rate of the wheel, and the accuracy of the determined adhesion coefficient is effectively improved.

    本申请提供一种车辆的附着系数的获取方法、装置、车辆及存储介质,涉及车辆技术领域,该方法包括:针对车辆的每个车轮,根据获取到的车速,车轮的轮速,计算车轮的滑移率,根据车轮的驱动力和车轮的垂直载荷,计算车轮的利用附着系数,根据车轮的利用附着系数以及车轮的滑移率,确定车轮的附着系数。在本技术方案中,针对车辆的每个车轮,基于该车轮的滑移率对该车轮的利用附着系数进行修正,有效提高了确定的附着系数的准确度。
