Abstract:
1. A vehicle steering control device comprising: a position detection sensor for detecting a position of a road boundary of a road disposed in front of a vehicle and positions of road accessories arranged around the road boundary; a road curvature radius calculation device for calculating an outer curvature radius of the road based on the positions of the road boundary and the road accessories detected by the position detection sensor; a turning radius calculation device for calculating an appropriate turning radius of the vehicle running on the road based on the outer curvature radius calculated by the road curvature radius calculation device; an appropriate distance calculation device for calculating an appropriate road boundary distance, which is defined by an appropriate distance between a front end of the vehicle and an outer road boundary disposed in front of the vehicle, based on the outer curvature radius and the appropriate turning radius; an actual distance calculation device for calculating an actual road boundary distance, which is defined by an actual distance between the front end of the vehicle and the outer road boundary disposed in front of the vehicle, based on the positions of the road boundary and the road accessories arranged around the road boundary detected by the position detection sensor; and a steering wheel angle acceptability determination device for determining acceptability of a steering wheel angle based on comparison between the appropriate road boundary distance and the actual road boundary distance.
