The present invention relates to a control method for idling anti-rollback of pure electric vehicle, which comprises the following steps: determining whether an anti-rollback control is needed by the current state of the vehicle or not with the vehicle controller according to the brake pedal, the handbrake device and the accelerator pedal; If needed, judging whether the working condition of the anti-rollback control is satisfied by the current states of the power battery, the motor controller, and the motor or not with the vehicle controller; If not satisfied, stopping the motor to output a torque; If satisfied, driving the motor to output the torque for the anti-rollback control. With this pure electric vehicle, the control method for idling anti-rollback of pure electric vehicle can be suitable for the pure electric vehicle, the pure electric vehicle uses the motor alone to drive the vehicle, therefore is very different from conventional cars in the control of the torque and the speed regulation, thus the present invention can be suitable for starting an electric vehicle at idle, prevents effectively an electric vehicle on a slope from rolling back, has a simple and quick processing procedure, and a stable and reliable performance, and lays a solid foundation for further development and application of the electric vehicle technology.
