The invention discloses an extended-range electric vehicle control method and device, an extended-range electric vehicle and a storage medium. The control method for the extended-range electric vehicle comprises the steps that when the extended-range electric vehicle is in an extended-range working mode, an extended-range controller obtains an engine rotating speed signal from an engine controller, and the external characteristic torque of an engine is determined according to engine rotating speed information; the range extending controller obtains available torque of a motor from a motor controller and determines target limiting torque according to the external characteristic torque of the engine and the available torque of the motor; and the current motor power generation torque is obtained through the range extending controller, and the motor output torque is determined according to the target limiting torque and the current motor power generation torque, so that a motor of the range extending electric vehicle is controlled through the motor output torque. The device effectively prevents reverse rotation of the engine, protects the engine from being damaged, and is safe and reliable.
