A brake-system damping device includes a first chamber, to which hydraulic pressure is to be applied, a second chamber, in which there is a compressible medium, and a first separating element for separating the first chamber from the second chamber. The brake-system damping device includes a third chamber, in which there is a compressible medium, and a second separating element for separating the second chamber from the third chamber. The second chamber is connected, for medium conduction, to the third chamber by means of a passage formed in the second separating element. A closure element is to be moved with the first separating element, by means of which closure element the passage is to be closed as soon as the hydraulic pressure has reached predefined pressure value in the first chamber.

Brake-system damping device

In a hydraulic brake system, which includes: a hydraulic pump which is driven by an electric motor and has the purpose of generating a fluid volume flow for the hydraulic brake system; a hydraulic connection for conducting the fluid volume flow between the hydraulic pump and a wheel brake; a reservoir for storing a fluid volume; wherein the reservoir is connected to the hydraulic connection by means of a switching valve, a method includes actuating the switching valve in such a way that by this means a fluid pulsation in the hydraulic connection is counteracted. Furthermore, the method may be implemented with a control unit and a hydraulic brake system.

Method for controlling a hydraulic brake system

In a method for controlling a hydraulic braking system, wherein the braking system includes a hydraulic pump that is driven by an electric motor so as to generate a volume of fluid flow for the hydraulic braking system. the electric motor is controlled in such a manner that fluid pulsation in the hydraulic braking system is counteracted by means of modulating a rotational speed of the electric motor. The modulation is generated by means of the control procedure. Furthermore, a device is designed and configured so as to perform the method.

Method for controlling a hydraulic braking system

In a hydraulic brake system, which includes: a hydraulic pump which is driven by an electric motor and has the purpose of generating a fluid volume flow for the hydraulic brake system; and a solenoid valve for controlling the fluid volume flow from the hydraulic pump to a wheel brake, a method includes actuating the solenoid valve in such a way that by this means a fluid pulsation at the wheel brake is counteracted. Furthermore, the method may be implemented in a corresponding device.
