The invention provides a single-pedal control system and method for a pure electric vehicle. The single-pedal control system comprises a single pedal, a whole vehicle controller, a motor controller and a braking system main-cylinder pressure regulator, wherein the single pedal is provided with an opening sensor; the single pedal and the opening sensor are connected to the whole vehicle controller through a rigid line; the motor controller and the braking system main-cylinder pressure regulator are respectively connected with the whole vehicle controller through a CAN bus; the whole vehicle controller divides the running conditions of the pure electric vehicle into a braking segment, a sliding segment and an acceleration segment according to the opening information of the single pedal, which is acquired by the open degree sensor. The segmented single pedal can meet requirements for running states, such as advancing/backing, sliding, braking, and the like, of the vehicle, so that the conventional two-pedal or three-pedal structure operations are simplified into single-pedal operations: deeply stamping the pedal so as to enable the vehicle run, moderately stamping the pedal so as to enable the vehicle to slide, slightly stamping the pedal so as to brake the vehicle, and loosening the pedal so as to stop the vehicle.
