Abstract
A steering control apparatus for a vehicle which prevents an interference between a steering operation performed by the steering control apparatus and a steering operation performed by a driver of the vehicle. A guide line provided on a vehicle moving lane is recognized by a forward image of the vehicle so as to set a target position on the vehicle moving lane based on a result of recognition of the guide line. A steering control operation is performed so that the vehicle moves to trace the target position. The steering control operation is started when a distance between the vehicle and the guide line is less than a first predetermined value. The steering control operation is ended when a distance between the vehicle and the guide line exceeds a second predetermined value which is greater than the first predetermined value.
