The invention discloses an electric vehicle torque control method and device and a vehicle. The method comprises the steps that in the vehicle climbing process, slip signals of vehicle wheels are monitored; if it is monitored that the front wheels and the rear wheels of the vehicle slip, the longitudinal acceleration value and the acceleration change rate of the vehicle are obtained; and based on the longitudinal acceleration value and the acceleration change rate, torque reduction control is conducted on the vehicle front axle and the vehicle rear axle, so that the longitudinal acceleration value is larger than zero, and the acceleration change rate is larger than or equal to zero. According to the method, torque reduction control is conducted on the vehicle with slipping on the basis of the longitudinal acceleration value and the acceleration change rate, so that the vehicle wheel torque is smoothly output, torque interruption is avoided, and the trafficability and driving safety are effectively guaranteed.
本发明公开了一种电动车扭矩控制方法、装置及车辆,所述方法包括:在车辆爬坡过程中,监测车辆车轮的打滑信号;若监测到车辆前轮以及后轮均存在打滑,则获取车辆的纵向加速度值以及加速度变化率;基于纵向加速度值以及加速度变化率,对车辆前轴以及车辆后轴进行降扭控制,以使得纵向加速度值大于零,加速度变化率大于或等于零。该方法针对存在打滑的车辆,基于纵向加速度值以及加速度变化率进行降扭控制,使得车辆车轮扭矩平顺输出,不出现扭矩中断,有效地保证通过性和行车安全。
