The invention relates to the technical field of new energy automobiles, and provides a range extender control method and device and a four-wheel drive range extending automobile. The method comprises the steps that if it is determined that the power driving mode of the four-wheel-drive extended-range automobile is a four-wheel driving mode, a power generation power request value is split into a first power generation power request value and a second power generation power request value based on the real-time automobile speed; a first control instruction is issued to a first range extending controller, so that the first range extending controller controls a first range extender based on the first power generation power request value to indirectly regulate and control the torque and the rotating speed of a front axle motor; and a second control instruction is issued to the second range extender, so that the second range extender is controlled by the second range extender based on the second power generation power request value to indirectly regulate and control the torque and the rotating speed of the rear axle motor. On one hand, a power battery is omitted, and the energy utilization rate is greatly improved; on the other hand, the rotating speeds and torques of the front and rear axle motors can be indirectly regulated and controlled through the first and second range extending controllers, so that the comprehensive performance of the range extender is improved.

    本申请涉及新能源汽车技术领域,提供了一种增程器控制方法、装置及四驱增程式汽车。该方法包括:若确定四驱增程式汽车的动力驱动模式为四轮驱动模式,则基于实时车速将发电功率请求值拆分为第一、第二发电功率请求值;向第一增程控制器下发第一控制指令,以使第一增程控制器基于第一发电功率请求值对第一增程器进行控制以间接调控前轴电机的扭矩和转速;向第二增程器下发第二控制指令,以使第二增程控制器基于第二发电功率请求值对第二增程器进行控制以间接调控后轴电机的扭矩和转速。本申请一方面省略了动力电池,大大提升了能量的利用率;另一方面可通过第一、第二增程控制器间接调控前、后轴电机的转速和扭矩,从而提升增程器的综合性能。
