The invention relates to the technical field of vehicle control, in particular to a torque output control method and system of a vehicle and the vehicle. Obtaining state information of the vehicle at the current moment, calculating a current road adhesion coefficient of the vehicle on the road where the vehicle is located at the current moment according to the state information, obtaining a theoretical driving torque slope of the vehicle according to the current road adhesion coefficient, and obtaining a real-time driving torque slope of the vehicle at the current moment; and according to the theoretical driving torque slope and the real-time driving torque slope, the vehicle is controlled to output the corresponding torque slope. In the embodiment, according to the requirement of the current road adhesion coefficient for driving, control is conducted from the slope level of the driving torque, feedforward control is conducted on slipping of the driving wheel when the torque is output, the driving smoothness under various road surfaces is improved, and no other performance loss exists.

    本发明涉及车辆控制技术领域,尤其涉及一种车辆的扭矩输出控制方法、系统及车辆。获取当前时刻车辆的状态信息,根据状态信息,计算当前时刻车辆在所在路面的当前路面附着系数,根据当前路面附着系数,得到车辆的理论驱动扭矩斜率,获取当前时刻车辆的实时驱动扭矩斜率,根据理论驱动扭矩斜率与实时驱动扭矩斜率,控制车辆输出对应扭矩斜率。本实施例中,根据当前路面附着系数对驱动的需求,从驱动扭矩斜率层面进行控制,在扭矩输出时已对驱动轮打滑进行前馈控制,提升各种路面下的驾驶平顺性,且无其他性能损失。
