The invention discloses a vehicle, a torque limiting method and device of the vehicle and a computer readable storage medium, and the method comprises the steps that when the vehicle is in a torque limiting working condition, a torque correction coefficient corresponding to the torque limiting working condition is obtained, and the driving torque of the last control period is obtained; according to the driving torque and the torque correction coefficient of the previous control period, the limiting torque of the current control period is determined; and according to the limiting torque of the current control period, the vehicle performance limiting torque and the target demand torque, the driving torque of the current control period is determined. According to the limiting method, the vehicle torque output can be limited when the vehicle is in the torque limiting working condition, and therefore the driving safety is improved.

    本发明公开了一种车辆及其扭矩限制方法和限制装置、计算机可读存储介质,所述方法包括:在车辆处于扭矩限制工况时,获取与扭矩限制工况对应的扭矩修正系数,并获取上一控制周期的驱动扭矩;根据上一控制周期的驱动扭矩和扭矩修正系数,确定当前控制周期的限制扭矩;根据当前控制周期的限制扭矩、车辆性能限制扭矩和目标需求扭矩,确定当前控制周期的驱动扭矩。本发明的限制方法,能够在车辆处于扭矩限制工况时,限制车辆扭矩输出,从而提升驾驶的安全性。
