The invention discloses an automobile electric power-assisted steering driving device and a control method thereof. The automobile electric power-assisted steering driving device comprises an electric power-assisted steering driving device body, a gearbox gear shell is arranged on the electric power-assisted steering driving device body, and a driven gear is arranged on a main transmission shaft in the center of the interior of the gearbox gear shell; change gear sets are symmetrically arranged on the two sides of the main transmission shaft, change gears are arranged on driving shafts in the centers of the change gear sets, a gear plectrum mechanism is arranged on one side of each change gear set, a movable ring is arranged on the inner side of a plectrum jaw on the gear plectrum mechanism, and the gear plectrum mechanism is connected with a driving air cylinder on a plectrum driver at one end. Each driving air cylinder drives a shifting piece to achieve meshing of a variable gear and a corresponding driven gear on the main transmission shaft, so that power-assisted steering driving of the main transmission shaft is achieved, the electric power-assisted steering driving device can achieve electric power-assisted steering driving, gear shifting power assisting can be achieved according to the rotating speed of a user, and the electric power-assisted steering is high in response speed and light in steering.
