PROBLEM TO BE SOLVED: To reduce the number of electronic control units, simplify a configuration, and reduce its cost. SOLUTION: A driving force can be given to a steering mechanism 10 from a main steering actuator 51M and an auxiliary steering actuator 51S. A steering wheel 30 is provided while it is not connected with the steering mechanism 10 mechanically, and steering resistance is given to the steering wheel 30 from a reaction force spring 20. A main steering drive circuit 53M and an auxiliary steering drive circuit 53S supplying drive currents to the main steering actuator 51M and the auxiliary steering actuator 51S, respectively, are controlled by a main steering control part 61M and an auxiliary steering control part 61S, respectively. The main steering control part 61M and the auxiliary steering control part 61S are controlled by a main control part 80 in an integrated manner. The main control part 80 and the main steering control part 61M are integrated in one electronic control unit 60. |
