The invention relates to the field of hybrid vehicles, in particular to a hybrid power vehicle power output control method, a system, and a motor vehicle. The hybrid power vehicle power output controlmethod comprises the steps: determining the current altitude of a vehicle; determining a power demand range according to the power generation power, the power generation efficiency and the margin coefficient of an engine; and determining the calibration rotating speed of a generator according to the current altitude, a calibration parameter table and the power demand range; according to differentaltitudes, formulating different power output modes, and changing the corresponding relation between power requirements and rotating speed calibration so as to ensure the power requirements of the whole vehicle. The current altitude of the vehicle is judged, the power demand range is determined according to the power change of the engine, and then the calibrated rotating speed of the generator isdetermined according to the current altitude, the calibration parameter table and the power demand range, so that the generator can select the calibrated rotating speed in a targeted manner, and thepower demand of the whole vehicle can also be ensured in a high-altitude area.

    本发明涉及混合动力车领域,尤其涉及一种混合动力车辆动力输出控制方法、系统和机动车。本发明所述的混合动力车辆动力输出控制方法包括:判断车辆的当前海拔高度;根据发动机的发电功率、发电效率和余量系数确定功率需求区间;根据所述当前海拔高度、标定参数表和所述功率需求区间确定发电机的标定转速。根据不同的海拔高度,制定不同的动力输出模式,改变动力需求与转速标定的对应关系,以保证整车的动力需求。通过判断车辆的当前海拔高度,根据发动机功率变化,确定功率需求区间,再根据当前海拔高度、标定参数表和功率需求区间确定发电机的标定转速,使发电机有针对性的选取标定转速,在高海拔地区也能够保证整车的动力需求。
