One kind of extended-vehicle controller and the electric vehicle and its power generation control method and system

The present invention discloses a method of increasing the power generation control program of an electric vehicle, comprising: acquiring vehicle power generation, power generation and decomposition of the target vehicle speed and target torque; controlling the rotational speed of the generator based on the target speed mode starts, while controlling the engine constant output torque; acquired in real time the speed of the generator, when the generator speed reaches the target speed, the target engine output torque is controlled; when the detected battery power meets a preset condition or an external power supply to the power charging the battery, and the engine control generators stop running. The present invention also discloses an extended-vehicle controller and the electric vehicle and its power generation control system. Power generation control method of the present invention provides extended-electric vehicle, the rotation speed of the generator control loop to achieve the power generation control program by an electric vehicle, the engine response to solve slow, reducing the generation power of the engine rotational speed closed loop control to bring large, low economy and vehicle stability problems.
