Vehicle stabilization control device
First Claim
1. A vehicle stabilization control device comprising:
- an actual turning state quantity acquisition unit that acquires an actual turning state quantity that indicates an actual turning state of a vehicle;
a control quantity computation unit that, in order to control a braking force for each of the wheels of the vehicle such that understeer of the vehicle is suppressed, in yaw priority mode, computes a target control quantity for each of the wheels, based on the actual turning state quantity and on a first computation characteristic giving higher priority to an imparting of a yaw moment to the vehicle than to a deceleration of the vehicle or, in a deceleration priority mode, based on the actual turning state quantity and on a second computation characteristic giving higher priority to the deceleration than to the imparting of the yaw moment to the vehicle;
a control unit that controls the braking force for each of the wheels, based on the target control quantity for each of the wheels;
a curve information acquisition unit that acquires a shape of a curve that lies ahead in the direction of travel of the vehicle;
a vehicle speed acquisition unit that acquires a speed of the vehicle; and
a curve traverse possibility determination unit that determines a possibility that the vehicle can traverse the curve in a stable manner, based on the curve shape and the speed of the vehicle, whereincurve information acquisition unit when the possibility that the vehicle can traverse the curve in a stable manner is determined to be high and in the deceleration priority mode when the possibility that the vehicle can traverse the curve in a stable manner is determined to be low.

Abstract
A vehicle stabilization control device includes: an actual turning state quantity acquisition unit that acquires an actual turning state quantity indicating an actual turning state of a vehicle; a curve information acquisition unit that acquires the shape of a curve ahead of the vehicle; a vehicle speed acquisition unit that acquires speed of the vehicle; and a curve traverse possibility determination unit that determines a possibility that the vehicle can stably traverse the curve, based on the curve shape and speed of the vehicle; a control quantity computation unit that, to control braking force on each wheel and suppress understeering, computes a target control quantity for each wheel, based on the actual turning state quantity and on the possibility that the vehicle can stably traverse the curve; and a control unit controlling the braking force for each wheel, based on the target control quantity for each wheel.
