Device for controlling vehicle turn behavior with discrimination of drive direction

A device for controlling a turn running behavior of a vehicle having a vehicle body, front left, front right, rear left and rear right wheels, an engine for driving at least a rear pair or a front pair of the wheels, a steering system for steering at least the front pair or the rear pair of the wheels, and a brake system for braking each of the wheels, comprising:

• means for detecting at least one parameter with respect to the turn running behavior of the vehicle in addition to a drive direction thereof, the one parameter being indicative of changes of degree of desirability of the turn running behavior control according to changes of a magnitude thereof,
• means for calculating an amount for the turn running behavior control based upon the turn running behavior parameters detected by the turn running behavior parameter detection means,
• means for determining a start of the turn running behavior control according to the one turn running behavior parameter traversing a threshold value determined therefor, and
• means for executing the turn running behavior control by operating at least one of the engine and the brake system according to the turn running behavior control amount,
• wherein the turn running behavior control start determination means change the threshold value in a rearward drive of the vehicle as compared in a forward drive thereof such that the turn running behavior control is started at a lower degree of the desirability thereof in the rearward drive than in the forward drive.
