Abstract
Abstract A correction factor setting unit sets correction factors for a front-rear traction distribution control unit, an anti-lock brake control unit, a traction control unit, and a braking power control unit according to the situation of a road and the shape thereof which are inputted from a road information recognizing unit. At this time, the correction factors are preset values according to the situation of the road and the shape thereof so that the actions of the control units will be balanced with each other. Consequently, the plurality of vehicle behavior control units mounted in a vehicle act efficiently according to the situation of the road, on which the vehicle is driven forwards, and the shape thereof while quickly responding to the situation of the road and the shape thereof. Besides, the actions of the vehicle behavior control units are balanced with one another.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
181 words
A vehicle dynamics control system comprising: road information recognizing means for detecting and recognizing a situation of a road and a shape of the road; vehicle behavior control means for controlling a behavior of the vehicle, said vehicle behavior control means including at least a braking power control unit for controlling the behavior of the vehicle by using a braking force; and variable control means for, according to the situation of the road and the shape of the road, freely varying at least one of a magnitude of control and a sensibility of said vehicle behavior control means in intervening in associated control actions, wherein said braking power control unit judges whether a driving condition of the vehicle signifies a tendency toward one of oversteering and understeering; and wherein said variable control means varies a sensibility of said braking power control unit in intervening in an associated control action depending on whether the control action is performed to cope with the tendency toward the oversteering or the understeering according to the situation of the road and the shape of the road.
