The embodiment of the invention relates to the technical field of vehicle control, and discloses a vehicle control method based on a road surface adhesion coefficient, which comprises the following steps: matching with a pre-configured road surface state coefficient based on road surface state information to determine a road friction coefficient of a current road; receiving use state data of each tire in the target vehicle and vehicle driving state information; determining an actual friction coefficient between each tire and the ground based on the road friction coefficient of the current road and the use state data of each tire; and determining a road surface adhesion coefficient based on the vehicle driving state information and the actual friction coefficient. According to the vehicle control method based on the road surface adhesion coefficient, the friction coefficient between each wheel and the ground is determined by comprehensively calculating the road surface state information and the vehicle driving information, and then the adhesion coefficient between the whole vehicle and the ground is accurately determined; in this way, the stability of driving brake control is improved in an auxiliary mode.

    本发明实施例涉及车辆控制技术领域,公开了一种基于道路表面附着系数的车辆控制方法,包括:基于路面状态信息来与预先配置的路面状态系数进行匹配以确定当前道路的道路摩擦系数;接收目标车辆中各个轮胎的使用状态数据以及车辆行驶状态信息;基于当前道路的道路摩擦系数和各个轮胎的使用状态数据来确定各个轮胎与地面之间的实际摩擦系数;并基于车辆行驶状态信息以及实际摩擦系数来确定道路表面附着系数。本发明实施例中的基于道路表面附着系数的车辆控制方法其通过对路面状态信息以及车辆行驶信息进行综合计算来确定各个车轮与地面之间的摩擦系数,进而精准确定车辆整体与地面之间的附着系数;通过上述方式辅助提升驱动制动控制的平稳性。
