Abstract

Official abstract text for this publication.

A vehicle Ve comprises six wheels of front left and right wheels FW 1 FW 2 , middle left and right wheels MW 1 , MW 2 , and rear left and right wheels RW 1 , RW 2 . Each of in-wheel motors 21 - 26 is provided/installed in each of the wheels. An electronic control unit 41 calculates a target heave force for controlling a heave behavior, and a target pitching moment My for controlling a pitching behavior, using a state of a movement of a vehicle body Bo obtained from a movement state detecting sensor 43 . The unit 41 calculates a driving force and a braking force of the front wheels FW1 FW 2 and the rear wheels RW 1 , RW 2 , in order to achieve the calculated target heave force and the target pitching moment, and calculates a driving force and a braking force of the middle wheels MW 1 , MW 2 for suppressing a forward-and-backward movement of the vehicle, the movement caused by independently (simultaneously) controlling the behaviors coupling with each other.

First claim

Opening claim text (preview).

The invention claimed is: 1. A vehicle behavior control apparatus comprising: a force generating mechanism which makes front wheels and rear wheels of a vehicle generate a driving force or a braking force, independently from each other; suspension mechanisms, each of which connects each of said front wheels and said rear wheels, both arranged as unsprung articles of said vehicle, to a vehicle body arranged as a sprung article of said vehicle; and a control section which contro…
