ABSTRACT:
In a vehicle dynamics control (VDC) system for a four-wheel-drive vehicle employing a brake control system regulating braking forces applied to road wheels independently of each other and a differential mechanism controlling a differential motion between front and rear wheel axles, a VDC controller controls a braking force of each road wheel depending on whether the vehicle is in oversteering or understeering. The VDC controller includes a braking-force compensation section that compensates for a braking force of at least one of a first wheel, which is subjected to vehicle dynamics control, and a second wheel to which a transferred braking force is transferred from the first wheel through the differential mechanism, to reduce a braking force of the second wheel and to prevent the braking force of the second wheel from exceeding a lateral grip limit of the second wheel during the vehicle dynamics control.
