Vehicle movement control device and vehicle movement control method

Abstract

The present invention provides a vehicle movement control device to achieve both ride quality and minimization in travel time by setting a speed to make a physical quantity of an acceleration or jerk fall within a specified value in consideration of cooperation of longitudinal movement and lateral movement generated on a vehicle during travel. The vehicle movement control device includes: path command value calculation means that generates a path on which a vehicle travels; specified value setting means that sets a specified value of a physical quality of a vehicle behavior when traveling on the path; path feature point setting means that sets a path feature point based on the path and the specified value; and speed command value calculation means that calculates a speed for the vehicle to travel on the path based on the path, the specified value, and the path feature point. The speed command value calculation means sets a zero point of a longitudinal acceleration based on a path feature point that is a peak point of a curvature of the path, and sets a peak point of a longitudinal acceleration based on a path feature point that is a peak point of a distance derivative value of the curvature.
