摘要： A brake system for a motor vehicleincludes a first unit, a second unit, and a pressure medium reservoir which is under atmospheric pressure. The first unit includes a first electrically actuable pressure supply device having a hydraulic pressure chamber, wherein the first electrically actuable pressure supply device is hydraulically connected to a first and a second output pressure port of the first unit, and wherein the second unit includes a first input port, which is hydraulically connected to at least one first wheel port of the second unit, a second input port, which is hydraulically connected to at least one second wheel port of the second unit, a second electrically actuable pressure supply device, which is hydraulically connected to the at least one first and the at least one second wheel port, and at least one inlet valve per first and second wheel port.

摘要： A hydraulic brake system of a motor vehicle includes a linear actuator as a driver-independent pressure provision device and a hydraulic valve arrangement between the linear actuator and wheel brakes. In the case of a reduced availability of the linear actuator, a holding mode is carried out, in which the hydraulic pressure in the wheel brakes is shut in with the valve arrangement and a power output of the linear actuator is reduced, the system pressure gradient in the holding mode is measured, and a transition from the holding mode into an alternative mode is carried out based on the system pressure gradient.

摘要： 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.

摘要： A method for controlling a brake system comprises a linear actuator and a hydraulic pump. For a rapid pressure build-up, the linear actuator and the hydraulic pump are switched into synchronous operation at a rate of change of the braking request signal greater than a threshold value. The embodiments also relates to a brake system for motor vehicles.
