The invention discloses a vehicle and a control method and device thereof and a storage medium, the vehicle comprises at least two driving wheels, a motor for driving the driving wheels and a motor controller for controlling the motor, and the method comprises the steps that the rotating speeds of the at least two driving wheels and the driving state of the vehicle are obtained, and if the driving state is a non-slip state, the motor is driven to rotate; and if the rotating speed of the vehicle is detected and the vehicle has a slip trend according to the rotating speed, reducing the required torque of the vehicle to obtain a target torque, and controlling a motor controller according to the target torque. According to the method, the risk that the whole vehicle is out of control under the slipping working condition can be effectively reduced by monitoring the rotating speed of the driving wheels and monitoring the torque under the slipping working condition.
本发明公开了一种车辆及其控制方法、控制装置以及存储介质,车辆包括至少两个驱动轮、驱动驱动轮的电机和控制电机的电机控制器,方法包括:获取至少两个驱动轮的转速和车辆的行车状态,若行车状态为未打滑状态,且根据转速确定车辆存在打滑趋势,则对车辆的需求扭矩进行降扭,得到目标扭矩,并根据目标扭矩对电机控制器进行控制。该方法通过对驱动轮转速的监控以及打滑工况下扭矩的监控,可有效降低打滑工况下整车失控的风险。
