The invention relates to the field of new energy vehicles, and provides a range extender control method and device, a vehicle and a readable storage medium. The method comprises the steps that the current control power generation rotating speed is determined according to the current target power generation rotating speed and the current target power generation torque of the range extender; determining a target correction coefficient; determining a corrected power generation torque according to the current control power generation rotating speed, the current target power generation torque and the target correction coefficient; determining a target torque descending gradient and a target torque ascending gradient; calculating a current control power generation torque according to the corrected power generation torque, the target torque descending gradient and the target torque ascending gradient; and the current actual power generation rotating speed of the range extender is controlled to be dynamically transferred to the current control power generation rotating speed, and the current actual power generation torque of the range extender is controlled to be dynamically transferred to the current control power generation torque. The power generation efficiency, the power generation power stability and the power output response rate of the range extender can be considered in a complex scene, and the optimization of the comprehensive performance is achieved.
