The invention discloses an electric car double-motor front and rear torque transfer method, a control system and an electric car. The transfer method comprises the following steps that a steering wheel angle signal, a slope signal and a car speed signal are obtained; according to at least one of the obtained steering wheel angle signal, the obtained slope signal and the obtained car speed signal,the current working condition of the electric car is determined; according to the current working condition of the electric car, the front wheel torque and the rear wheel torque of the electric car are adaptively transferred. According to the electric car double-motor front and rear torque transfer method in the embodiment, by obtaining the steering wheel angle signal, the slope signal and the carspeed signal, the working condition of the electric car is judged, according to the current working condition of the electric car, the front wheel torque and the rear wheel torque of the electric carare transferred, it is ensured that the front wheel torque and the rear wheel torque are reasonably transferred under different working conditions of the electric car, and it is ensured that the electric car is high in controllability, stability and economical efficiency during driving.
