  • Method and device for estimating an admission pressure in a motor vehicle brake system
    Patent number: 6668634
    Abstract: A method for estimating an admission pressure prevailing between a main brake cylinder and an intake valve of a wheel brake cylinder of a motor vehicle brake system, with the admission pressure being estimated, taking into account a run-on voltage of a clocked-mode motor of a pump for recirculating brake fluid from an accumulator, located at the output end of the wheel brake cylinder, to the main brake cylinder of the brake system, and also taking into account an accumulator pressure determined in the accumulator.
