Abstract:
1. A motion control apparatus for a vehicle, comprising: a road data storing device for storing road data; a vehicle position detector for detecting a position of the vehicle based on the road data; a vehicle speed detector for detecting a speed of the vehicle; a corner radius calculating device for calculating a radius of a corner existing on a route on which the vehicle is traveling at present, based on the road data and the vehicle position; motion parameter detectors for detecting motion parameters expressing a turning motion state of the vehicle; an actual turning radius calculating device for arithmetically operating and estimating an actual turning radius when the vehicle enters the corner, based on at least the vehicle speed and the motion parameters; a radius difference calculating device for calculating a difference between the radius calculated by the corner radius calculating device and the actual turning radius; and a motion state control device for controlling a motion state of the vehicle based on a calculation by the radius difference calculating device so that the actual turning radius becomes close to the radius of the corner.
