The invention relates to the technical field of commercial vehicle electric drive axles, in particular to an electric drive axle control system and a commercial vehicle. The electric drive axle control system comprises a left second axle motor, a right second axle motor, a left second axle wheel, a right second axle wheel, a third axle motor, a differential mechanism, a left third axle wheel, a right third axle wheel and a controller. The left second-axle motor is connected with the left second-axle wheel through the left second-axle speed change mechanism, the right second-axle motor is connected with the right second-axle wheel through the right second-axle speed change mechanism, and the controller can control the driving torque of the left second-axle motor and the driving torque of the right second-axle motor respectively. The three-axle motor is connected with the differential mechanism through the three-axle speed change mechanism, and the differential mechanism is connected with the left three-axle wheel and the right three-axle wheel. And when the actual speed of the whole vehicle is greater than the preset high-speed limit value, the controller controls the three-axle motor to start and controls the left two-axle motor and the right two-axle motor to close. According to the electric drive axle control system and the commercial vehicle, the technical problems existing in an electric drive axle of an existing commercial vehicle are solved.
