Drift-out suppress control device of vehicle improved for termination of control

摘要

A drift-out suppress control device of a vehicle having a mechanism for estimating a liability of the vehicle body to drift out for producing a drift-out quantity which generally increases along with increase of the drift-out liability; a brake mechanism for selectively applying a variable braking force to each wheel; and a control mechanism for controlling the brake mechanism according to the drift-out quantity so as variably to apply a braking force to rear left and rear right wheels with a target value therefor for suppressing the vehicle body against drifting out, the target value being generally proportional to the drift-out quantity and being divided between the rear left and rear right wheels according to a distribution ratio, wherein the control mechanism decreases a share of the distribution ratio for one of the rear left and rear right wheels serving at the inside of a turn to be progressively lesser relative to a share of the distribution ratio for the other of the rear left and rear right wheels serving at the outside of the turn as the drift-out control approaches the end thereof.
