Abstract:
1. A vehicle control system for controlling a vehicle, comprising: a distance obtaining means for obtaining a distance between the vehicle and a road associated object on a road, wherein the road associated object is an object located along an extension line of a traveling direction of the vehicle, and at a boundary of a curve of the road or in a vicinity of the boundary, wherein the curve exists ahead of the vehicle; an evaluation index calculating means for calculating an approaching/separating state evaluation index that indicates a positional relationship between the vehicle and the road associated object, wherein: a curvature radius obtaining means for obtaining a curvature radius of the curve; a target vehicle speed setting means for setting a target vehicle speed of the vehicle, with which the vehicle travels along the curve, based on the curvature radius of the curve; a vehicle speed obtaining means for obtaining a current speed of the vehicle; a target vehicle deceleration calculating means for calculating a target vehicle deceleration, with which the vehicle is controlled to travel so that the vehicle travels along the curve with the target vehicle speed, based on the approaching/separating state evaluation index, the distance, the current speed of the vehicle, and the target vehicle speed; and a vehicle control means for controlling the vehicle to decelerate such that a deceleration of the vehicle coincides with the target vehicle deceleration, when the current speed of the vehicle is larger than the target vehicle speed.
