MOVEMENT CONTROL DEVICE FOR VEHICLE
First Claim
1. A movement control device for a vehicle which controls a movement of the vehicle equipped with front wheels steered, the movement control device being configured to perform the process of:
- obtaining a yaw-rate relating quantity which relates to a yaw rate of the vehicle;
determining whether a turn-back steering of the vehicle is conducted or not; and
controlling a drive force of the vehicle such that the drive force is decreased according to the yaw-rate relating quantity,wherein said controlling of the drive force of the vehicle is configured such that when the turn-back steering is not conducted, the amount of said drive-force decreasing is increased with a specified increasing rate as the yaw-rate relating quantity increases, the specified increasing rate being configured to become smaller as the yaw-rate relating quantity increases, and when the turn-back steering is conducted, the drive force is increased in a case in which an absolute value of a steering angle of the vehicle decreases.

Abstract
A movement control device for a vehicle comprises a yaw-acceleration calculation portion to calculate a target yaw acceleration of the vehicle, a turn-back steering determination portion to determine whether a turn-back steering of the vehicle is conducted or not, and a drive-force control portion to a drive force of the vehicle. The control of the drive-force control portion is configured such that when the turn-back steering is not conducted, the amount of drive-force decreasing is increased with a specified increasing rate as the target yaw acceleration increases, the specified increasing rate becoming smaller as the target yaw acceleration increases, and when the turn-back steering is conducted, the drive force is increased in a case in which an absolute value of a steering angle of the vehicle decreases.
