Stability control device of vehicle for relieving drive wheels from side slipping
First Claim
1. A behavior control device of a vehicle having a vehicle body, front left, front right, rear left and rear right wheels supporting the vehicle body, a steering system for steering the front left and front right wheels, a brake system for selectively variably braking each of the front left, front right, rear left and rear right wheels, and a drive system including an engine for selectively variably driving a pair of left and right drive wheels by fuel energy and for selectively variably braking said pair of left and right drive wheels due to air pumping energy consumption, said pair of drive wheels being the rear left and rear right wheels when the vehicle is a rear drive vehicle or the front left and front right wheels when the vehicle is a front drive vehicle, another pair of the front left and front right or rear left and rear right wheels being a pair of driven wheels, the behavior control device comprising:
- a means for estimating slip ratio of the left and right drive wheels;
a means for estimating lateral force acting at the vehicle body due to turn running of the vehicle to provide a factor representative of said lateral force; and
a means for estimating a target braking force to be generated in one of the pair of driven wheels based upon said slip ratio and said factor, said one driven wheel serving at the outside of the turn running when the vehicle is a rear drive vehicle or the inside of the turn running when the vehicle is a front drive vehicle;
said brake system being adapted to brake said one driven wheel to generate said target braking force therein.

Abstract
A behavior control device of a vehicle having a means for estimating slip ratio of a pair of left and right drive wheels; a means for estimating lateral force acting at the vehicle body due to its turn running to provide a factor representative of the lateral force; and a means for estimating a target braking force to be generated in one of a pair of front driven wheels serving at the outside of the turn when the vehicle is a rear drive vehicle or one of a pair of rear driven wheels serving at the inside of the turn when the vehicle is a front drive vehicle, based upon the slip ratio and the factor; so that the brake system of the vehicle brakes the front driven wheel serving at the outside of the turn or the rear driven wheel serving at the inside of the turn to generate the target braking force.
