The invention relates to a power control method and device of a diesel engine range extender, electronic equipment and a vehicle, and relates to the field of vehicles, the method comprises the steps that the whole vehicle demand power is determined according to one or more of the running speed of the vehicle, the electric quantity of a power battery, an accelerator pedal signal and a brake pedal signal, and under the condition that the whole vehicle demand power is larger than zero, the electronic equipment is started; the working rotating speed of an engine in the range extender is determined according to the vehicle speed interval where the running vehicle speed is located, then the corresponding preselected power of the range extender is obtained according to the working rotating speed of the engine, and the range extender is controlled to output power according to the preselected power by adjusting the torque of a generator in the range extender. The pre-selected power of the range extender can be determined according to the running speed under the condition that the whole vehicle has the power requirement, energy waste caused by the fact that a diesel engine continuously outputs a large working point and high emission amount caused by frequent rotating speed and torque changing are avoided, and energy consumption and emission amount can be balanced.

    本公开涉及一种柴油机增程器的功率控制方法、装置、电子设备及车辆,涉及车辆领域,该方法包括:根据车辆的行驶车速、动力电池电量、加速踏板信号和制动踏板信号中的一种或多种确定整车需求功率,在整车需求功率大于零的情况下,根据行驶车速所在的车速区间,确定增程器中的发动机的工作转速,再根据发动机的工作转速获取对应的增程器的预选功率,通过调整增程器中的发电机的扭矩,控制增程器按照该预选功率进行功率输出。能够在整车具有功率需求的情况下,根据行驶车速确定增程器的预选功率,避免柴油机持续在输出较大的工作点造成的能量浪费和频繁变动转速和扭矩造成的高排放量,能够平衡能量消耗和排放量。
