The embodiment of the invention relates to a method, device and equipment for determining a road adhesion coefficient, a vehicle and a program product. The method includes, in response to the vehicle being braked and the speed of the vehicle being greater than a threshold speed, determining a first accumulated slip rate for a wheel of a plurality of wheels of the vehicle. The method further includes determining a second accumulated slip rate for the vehicle based on the first accumulated slip rate for the wheel. The method further includes determining a road adhesion coefficient of the vehicle based on the second accumulated slip rate for the vehicle. According to the method disclosed by the embodiment of the invention, the current road adhesion coefficient can be sensed and accurately identified in advance during partial braking, so that the threshold value and the pressure of the anti-lock braking system can be accurately controlled, and good vehicle controllability and safety are provided for a driver.

    本公开的实施例涉及用于确定路面附着系数的方法、装置、设备、车辆和程序产品。该方法包括响应于车辆被制动并且车辆的速度大于阈值速度,确定针对车辆的多个车轮中的车轮的第一累积的滑移率。该方法还包括基于针对车轮的第一累积的滑移率,确定针对车辆的第二累积的滑移率。该方法进一步包括基于针对车辆的第二累积的滑移率,确定车辆的路面附着系数。通过本公开的实施例的方法,使得在部分制动时可以提前感知并准确识别当前路面附着系数,从而可以准确进行防抱死刹车系统的阈值和压力的控制,为驾驶员提供良好的车辆操控性和安全性。
