Vehicle motion control apparatus
First Claim
1. A vehicle motion control apparatus, comprising:
- a first means for applying a first braking force to at least an outer wheel, relative to a first turning direction of a vehicle, for suppressing oversteer of the vehicle, when the vehicle is determined to be skidding while the vehicle is turning;
a second means for detecting a steering angle in a case where the vehicle turns in the first turning direction;
a steering-turning-state determining means for determining whether or not a steering operation performed by a driver corresponds to a steering-turning state on the basis of changes in the detected steering angle under a condition that the first braking force is acting on at least the outer wheel;
a steering-turning-back state determining means for determining whether or not the steering operation performed by the driver is a steering-turning-back state on the basis of whether or not a sign of a difference of the steering angle per unit time, which is obtained while the first braking force is acting at least on the outer wheel, is opposite to the sign of the difference of the steering angle per unit time in a case where the steering operation performed by the driver is determined to be in the steering-turning state; and
a third means for applying a second braking force, which is set to be smaller than the first braking force applied by the first means, to at least one of the inner wheels, which is located at a position horizontally opposite from the outer wheel to which the first braking force is applied, based upon a determination that the steering operation performed by the driver is the steering-turning-back state.

Abstract
A vehicle motion control apparatus includes a first means applying a first braking force to an outer wheel, relative to a turning direction, for suppressing oversteer when the vehicle is judged to be skidding in vehicle turning movement, a second means obtaining a state of a driver'"'"'s steering operation in the vehicle turning movement, a third means applying a second braking force, set to be smaller than the first braking force, to a wheel located at a horizontally opposite side of the outer wheel to which the first braking force is applied, when the state of the driver'"'"'s steering operation is judged to be in a steering turning back state, in which a steering wheel is turned from a turning direction to a reverse direction of the turning direction, based on the state of the driver'"'"'s steering operation obtained by the second means.
