The invention relates to the technical field of new energy vehicles, and provides a generator speed regulation control method and device of a hybrid power vehicle. The method comprises the steps that when the hybrid power vehicle is in a series-parallel connection mode switching process, a generator speed regulation request of the hybrid power vehicle is activated, and generator speed regulation state parameters of the hybrid power vehicle are obtained; if the speed regulation state parameter of the generator meets the first speed regulation control condition, setting a target speed regulation control mode of the generator as a rotating speed control mode, and performing speed regulation control on the generator based on the rotating speed control mode; and if the speed regulation state parameter of the generator meets a second speed regulation control condition, setting a target speed regulation control mode of the generator as a torque control mode, and performing speed regulation control on the generator based on the torque control mode. According to the invention, speed regulation control can be carried out on the generator timely and flexibly, and the reliability and the effectiveness of the hybrid power system of the whole vehicle in the series-parallel connection mode switching process of the hybrid power vehicle are improved.
