• a preceding vehicle turning recognizing portion that recognizes turning of the preceding vehicle to the right or the left;
• an own vehicle turning recognizing portion that recognizes turning of the own vehicle and a direction of the turning of the own vehicle, based on the intention of the driver received by the turning intention receiver;
• and
• a steering-force control portion that executes a steering-force control in turning in which the steering-force motor applies, to the wheel, the steering force for assisting the turning of the own vehicle along the traveling track of the preceding vehicle identified by the traveling track identifying portion, when the turning of the preceding vehicle recognized by the preceding vehicle turning recognizing portion is turning at an intersection that is present on a traveling path of the own vehicle and a direction of the turning of the preceding vehicle at the intersection coincides with the direction of the turning of the own vehicle recognized by the own vehicle turning recognizing portion.
