Abstract
本公开涉及车辆控制领域,提供了一种车轮的控制方法、电子设备及车辆,在附着力低于预设附着力阈值的路面上制动时,检测到车辆存在车轮抱死,确定车辆的当前制动力,根据所述当前制动力确定目标制动紧急等级;根据所述目标制动紧急等级确定车辆对应的目标前轴控制力及目标后轴控制力;根据目标前轴控制力控制车辆前轮,根据目标后轴控制力控制车辆后轮。即在低附路面存在车轮抱死现象时,根据紧急制动紧急确定对应的目标前轴控制力及目标后轴控制力,使得目标前轴控制力及目标后轴控制力与车辆当前制动力更加匹配。同时,不完全依靠制动防抱死系统进行制动,进而减少低附路面对制动防抱死系统的影响,缩短刹车距离,提高了行车的安全性。

The invention relates to the field of vehicle control, and provides a control method of wheels, electronic equipment and a vehicle, wherein when the adhesion force is lower than a preset adhesion force threshold value, the wheel locking of the vehicle is detected, the current braking force of the vehicle is determined, and a target braking emergency level is determined according to the current braking force; and controlling front wheels of the vehicle according to the target front axle control force and controlling rear wheels of the vehicle according to the target rear axle control force. When the wheel locking phenomenon exists on the low-traction surface, corresponding target front axle control force and target rear axle control force are determined according to emergency braking emergency, so that the target front axle control force and the target rear axle control force are more matched with the current braking force of the vehicle. Meanwhile, the anti-lock braking system is not completely relied on for braking, so that the influence of a low-adhesion road surface on the anti-lock braking system is reduced, the braking distance is shortened, and the driving safety is improved.
