A control system for a vehicle (1) provided with a differential mechanism (3) that applies a torque difference to left and right wheels (5) and two electric motors (2) coupled to the differential mechanism (3), the control system including: two control units (11, 12) being connected to each other via high-speed communication means and each controlling one of the two electric motors (2); a first rotation speed sensor (26R) that detects a first rotation speed of a first electric motor (2R) of the two electric motors (2) and outputs the first rotation speed to the two control units (11, 12); a second rotation speed sensor (26L) that detects a second rotation speed of a second electric motor (2L) of the two electric motors (2) and outputs the second rotation speed to the two control units (11, 12); and a superordinate control unit (10) that calculates demanded torques of the two electric motors (2) based on vehicle information of the vehicle (1). At least a first control unit of the two control unites (11, 12) calculates two assigned torques to achieve the demanded torques calculated in the superordinate control unit (10) based on detection signals of the two rotation speed sensors (26R, 26L).
