The invention discloses a driving system and a driving method for a hybrid electric vehicle. The system is characterized in that an engine is connected with a planet carrier of a first planet row; the first motor is connected with a sun gear of the second planet row; a sun gear of the first planet row is connected with a sun gear of the second planet row; a first brake brakes a gear ring of the first planet row; a second brake brakes a gear ring of the second planet row; a planet carrier of the second planet row is connected with a first differential through a first speed reducer; the first differential is connected with a first driving shaft; the second motor is connected with a second differential through a second speed reducer; the second differential is connected with a second driving shaft; the first motor and the second motor are connected with the motor controller; and the motor controller is connected with the power battery. According to the driving system and method for the hybrid electric vehicle, under the condition that only two motors are needed, the complete four-wheel-drive function is achieved, the structure is simple, control is easy, the vehicle space is saved, and the production cost is effectively reduced.
