Apparatus for acquiring lateral acceleration at the center of gravity of vehicle, and motion control apparatus for vehicle
First Claim
1. A center-of-gravity-position lateral acceleration acquisition apparatus for a vehicle equipped with a lateral acceleration sensor which is installed at a position remote from the center of gravity of the vehicle and which detects lateral acceleration of the vehicle generated at that position, the apparatus comprising:
- correction means for correcting the detected lateral acceleration by making use of a first relationship among yaw rate of the vehicle, lateral acceleration generated at the center of gravity, and the detected lateral acceleration, and a second relationship between the yaw rate and the lateral acceleration generated at the center of gravity during a predetermined stable travel, the yaw rate being eliminated by combination of the first and second relationships; and
acquisition means for acquiring the lateral acceleration generated at the center of gravity, as corrected center-of-gravity-position lateral acceleration, through the correction of the detected lateral acceleration.

Abstract
A center-of-gravity-position lateral acceleration acquisition apparatus of the invention is applied to a vehicle equipped with a lateral acceleration sensor which is installed at a position remote from the center of gravity of the vehicle and which detects lateral acceleration of the vehicle at that position. The apparatus acquires lateral acceleration of the vehicle at the center of gravity of the vehicle by correcting the detected lateral acceleration by making use of two relationships; i.e., a first relationship which holds among yaw rate of the vehicle, the lateral acceleration of the vehicle at the center of gravity of the vehicle, and the detected lateral acceleration, and a second relationship which holds between the yaw rate of the vehicle and the lateral acceleration of the vehicle at the center of gravity of the vehicle during a predetermined stable travel.
