Vehicle Motion Control Device
First Claim
1. A vehicle motion control device, comprising:
- curve shape acquisition means for acquiring a shape of a curve present in front of a currently traveling vehicle;
vehicle position acquisition means for acquiring a position of the vehicle; and
vehicle motion control arithmetic means for computing, on a basis of the shape of the curve and the position of the vehicle, a command value relating to longitudinal acceleration to be caused to the vehicle;
wherein, if the longitudinal acceleration command value assumes that a direction in which the vehicle is traveling is plus, the vehicle motion control arithmetic means computes a plurality of different negative longitudinal acceleration command values during a time interval from before the vehicle reaches a near end of the curve, until the vehicle has approached the curve and traveled to a site having a constant or maximum curvature of the curve.

Abstract
A vehicle motion control device includes curve shape acquisition means for acquiring a shape of a curve present in front of a currently traveling vehicle, vehicle position acquisition means for acquiring a position of the vehicle, and vehicle motion control arithmetic means for computing, on the basis of the shape of the curve and the position of the vehicle, a command value relating to longitudinal acceleration to be caused to the vehicle. During a time interval from before the vehicle reaches a near end of the curve, until the vehicle has approached the curve and traveled to a site having a constant or maximum curvature of the curve, the vehicle motion control arithmetic means computes a plurality of different negative longitudinal acceleration command values. Thus, even when there is no lateral motion, the vehicle motion control device accelerates/decelerates the vehicle while improving a driver'"'"'s feeling of slowdown.
