The invention discloses a vehicle, a speed limiting control method and device thereof and a storage medium. The method comprises the steps that the current request driving torque, the target speed limiting value and the current vehicle speed of the vehicle are obtained; when the current vehicle speed is larger than the target speed limit value, a feedforward speed limit compensation value is obtained; driving compensation torque is determined according to the target speed limit value, the feedforward speed limit compensation value and the current vehicle speed; and the driving torque of the vehicle is determined according to the driving compensation torque and the current request driving torque. According to the method, when the current vehicle speed of the vehicle is larger than the target speed limit value, the driving torque of the vehicle can be compensated according to the current request driving torque, so that the vehicle can run below the maximum speed limit under different request driving torques and different speed limit requirements; and the same good dynamic performance can be kept under the high-speed limit value and the low-speed limit value, so that the vehicle can stably run under the limited vehicle speed.

    本发明公开了一种车辆及其限速控制方法和装置、存储介质,所述方法包括:获取车辆当前请求驱动扭矩、目标限速值和当前车速;在当前车速大于目标限速值时,获取前馈限速补偿值;根据目标限速值、前馈限速补偿值和当前车速确定驱动补偿扭矩;根据驱动补偿扭矩与当前请求驱动扭矩确定车辆的驱动扭矩。本发明的方法能够在车辆的当前车速大于目标限速值时,根据当前请求驱动扭矩对车辆的驱动扭矩进行补偿,从而使得车辆能够在不同请求驱动扭矩和不同限速需求下都能保持在最高限制车速以下的行驶,并且在高速限值和低速限值下都能够保持同样良好的动态性能,使车辆平稳地行驶在限制车速下。
