  • Electronically controlled hydraulic brake system
    Patent number: 8651587
    Abstract: A hydraulic brake system equipped for anti-slip control and for active brake interventions has a self-priming pump. A pressure retention valve prevents the brake system's low-pressure accumulator and the wheel brakes from being evacuated below atmospheric pressure during a sensitive brake operation. A two-position valve deactivates the bias of the pressure retention valve by opening a fluid path from the low-pressure accumulator to the pump when it is desired that the wheel brakes be retracted farther to reduce drag and excessive wear of the brake friction elements.
    Type: Grant
