Vehicle motion stability control apparatus
First Claim
1. A vehicle motion stability control apparatus for controlling at least one of braking force and driving force applied to a vehicle, to stabilize a motion thereof, comprising:
- angular velocity detection means for detecting an angular velocity about a single axis tilted in a longitudinal direction of said vehicle to a normal axis of said vehicle;
actual motion state variable calculation means for calculating an actual motion state variable indicative of an actual vehicle motion state variable of said vehicle, on the basis of the angular velocity detected by said angular velocity detection means;
desired motion state variable setting means for setting a desired motion state variable indicative of a desired vehicle motion state variable of said vehicle;
motion state variable deviation calculation means for calculating a deviation between the desired motion state variable set by said desired motion state variable setting means and the actual motion state variable calculated by said actual motion state variable calculation means; and
control means for controlling at least one of the braking force and driving force applied to said vehicle, on the basis of the deviation calculated by said motion state variable deviation calculation means.

Abstract
An angular velocity detection device is provided for detecting an angular velocity about a single axis tilted in a longitudinal direction of a vehicle to a normal axis thereof. An actual motion state variable of the vehicle is calculated on the basis of the detected angular velocity. At least one of the braking force and driving force applied to a vehicle is controlled to stabilize a yawing motion and a rolling motion of the vehicle, on the basis of a motion state variable deviation between a desired motion state variable and the actual motion state variable, e.g., a deviation between a yaw velocity and a roll velocity of the vehicle.
