The invention discloses a power control method and system in a plateau environment and a vehicle, and particularly relates to the technical field of vehicles. Under the condition that the vehicle is determined to be in the plateau environment, firstly, a target altitude correction coefficient corresponding to the current environment pressure is determined according to altitude correction coefficients calibrated under different environment pressures; then the target altitude correction coefficient is adopted to correct the engine torque requested by a driver, and the actual engine torque of the vehicle under the current environment pressure is determined; and finally, the vehicle is subjected to power output according to the actual engine torque, so that the accuracy of the output torque of the whole vehicle and the driving perception dynamic property are improved, the NVH problem caused by insufficient power of the vehicle is solved, a gear shifting line in a plateau mode does not need to be specially developed for the plateau environment, and the implementation cost is lower. And the adjustable range of the engine torque is wider, so that the current power output of the vehicle better meets the driving requirement under the plateau environment.

    本发明公开了一种高原环境下动力控制方法、系统以及车辆,具体涉及车辆技术领域,本发明在确定车辆处于高原环境的情况下,首先根据不同环境压力下标定的海拔修正系数,确定了当前环境压力对应的目标海拔修正系数;然后采用该目标海拔修正系数对驾驶员请求的发动机扭矩进行修正,确定所述车辆在当前环境压力下的实际发动机扭矩;最后依据所述实际发动机扭矩对车辆进行动力输出,如此提升了整车输出扭矩的精准度和驾驶感知动力性,解决了车辆因动力不足所带来的NVH问题,且无需专门针对高原环境开发高原模式下的换挡线,实现成本更低,发动机扭矩可调节范围更广,使得车辆当前的动力输出更符合高原环境下的驾驶需求。
