ABSTRACT:
A first compensation torque T1, a second compensation torque T2and a third compensation torque T3are added to a basic assist torque Tas. In this case, the second compensation torque T2and the third compensation torque T3are corrected by multiplying them by a common control gain G that is determined by the steering torque Th and the vehicle speed v. Therefore, since the two compensation control amounts are corrected through multiplication by the common control gain G, no interference occurs between the compensation controls. Besides, when the direction in which the total (T2+T3) of the pre-correction second compensation torque T2and the pre-correction third compensation torque T3acts is the same direction as the steering torque Th, the multiplication by the control gain G is avoided.
