Abstract
A method for reducing pressure peaks in hydraulic brake systems comprises an electrically operated pressurization device. A drive resistance variable of the pressurization device is measured, for example the torque. A speed variable of the pressurization device is measured. A quotient of the drive resistance variable and the speed variable is calculated. The quotient is monitored for the occurrence of a jump and, in the case of a determined jump, a speed requirement of the pressurization device is reduced and/or a hydraulic valve for pressure dissipation is actuated.
