Abstract: A vehicle behavior control apparatus mounted in a vehicle to control steering of the vehicle. A virtual road outline, which is an outline of a drivable road region where the vehicle will travel, is determined on the basis of detection results from a location sensor. The virtual road outline is reconstructed as a sequence of road segments, such as straight road segments, and right- and left-hand curved road segments. When a current road segment where the vehicle is currently present is a right- or left-hand curved road segment, a subsequent road segment where the vehicle will be present subsequently is tentatively set to a straight road segment until the vehicle reaches the subsequent road segment. The steering angle is controlled so that a virtual-road boundary distance is adapted to a proper distance from the vehicle to a boundary of the virtual road outline situated in front of the vehicle.

Abstract: A vehicle control device includes: a distance-acquisition section acquiring a path end distance between a vehicle and an end of a turn-travel path, on which the vehicle travels with turning; a path-width-acquisition section acquiring a path width of the turn-travel path; a velocity-acquisition section acquiring a velocity of the vehicle; an anticipated-curvature-radius-acquisition section acquiring a curvature radius of an anticipated turn-travel path obtained by assuming that the turn-travel path starts from a pre-turn position, based on the path width and the path end distance obtained at the pre-turn position; a target-velocity-setting section setting a target velocity at which the vehicle should travel on the turn-travel path, based on the anticipated curvature radius; a target-acceleration/deceleration-calculation section calculating a target acceleration/deceleration for accelerating/decelerating the vehicle to the target velocity, based on the velocity of the vehicle and the target velocity, and a vehicle-control section performing acceleration/deceleration control based on the target acceleration/deceleration.
