Patent abstract
A first correction coefficient and a second correction coefficient are map-searched based on a steering force applied by a driver to a steering wheel. A steering actuator is controlled based on an actuator driving electric current obtained by adding the product of an automatic steering control electric current and a first correction coefficient to the product of a power steering control electric current and a second correction coefficient. With an increase of the steering force, the first correction coefficient decreases and the second correction coefficient increases, so that a proportion of power steering control increases with respect to a proportion of automatic steering control.
