Abstract
A wheel brake pressure controlling system includes a brake pressure operating circuit for selectively supplying to a wheel brake a primary pressure generated by a vacuum booster in response to the depression of a brake pedal and a secondary pressure generated by a hydraulic pressure pump which is driven by an electric motor, a microcomputer for estimating a turning of vehicle, determining if a turning of the vehicle is in a over- or under-steer region, and for determining a wheel brake, the pressure of which is to be intensified if the turning of the vehicle lies in the over- or under-steer region, and an output controller for supplying the secondary pressure to the wheel brake which has been thus determined, through the brake pressure operating circuit. The microcomputer determines if the turning of a vehicle occurs in a reference region located outside the over- or under-steer region, and whenever the turning of the vehicle occurs in the reference region, drives the second source of pressure for generating the secondary pressure, determines a wheel brake which is to be intensified, and automatically intensifies the wheel brake.
