The invention belongs to the technical field of vehicles, and relates to a vehicle control method, a controller, a vehicle and a readable storage medium. The vehicle control method comprises the steps that S1, the current slip rate and the current required torque are obtained; and S2, when the traction force control system is not activated, responding to the situation that the current slip rate is larger than or equal to a first slip rate threshold value, and obtaining the engine target torque corresponding to the adhesion coefficient of the current road. And S3, in response to the fact that the current demand torque is larger than the engine target torque, torque adjusting operation is conducted based on the engine target torque. Therefore, the engine torque can be adjusted in advance by monitoring the increase trend of the slip rate before the traction control system is activated, so that the situation that the slip rate of the tire exceeds the optimal slip rate range due to response delay after the traction control system is activated subsequently is avoided, and the driving experience of the vehicle is improved.

    本申请属于车辆技术领域,涉及车辆控制方法、控制器、车辆及可读存储介质。车辆控制方法,包括:S1:获取当前滑移率及当前需求扭矩。S2:在牵引力控制系统未激活时,响应于当前滑移率大于或等于第一滑移率阈值,获取与当前道路的附着系数相对应的发动机目标扭矩。S3:响应于当前需求扭矩大于发动机目标扭矩,基于发动机目标扭矩进行扭矩调整操作。如此,本申请能够在牵引力控制系统激活前,通过监测滑移率的增加趋势,提前对发动机扭矩进行调整,以避免在后续牵引力控制系统激活后响应延迟,造成轮胎的滑移率超出最佳滑移率范围的情况,从而提升车辆的驾驶体验。
