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.
