Abstract: A voltage converter of a high voltage driver generates a high voltage applied to an electrorheological damper. The voltage converter and the electrorheological damper are electrically connected together through a connecting portion. The connecting portion comprises an electrode pin that connects the voltage converter and an electrode cylinder of the electrorheological damper; a ground pin that connects an external cylinder of the electrorheological damper and ground, and a ground detection pin disposed separately from the ground pin and connected to the ground through the external cylinder and the ground pin. When the ground detection pin and the ground are disconnected, the voltage converter discontinues the voltage generation with or without a command (control signal) of a sub-controller.

Abstract: A vibration damper for damping spring retraction and extension forces on vehicles includes an inner pressure medium cylinder, in which a piston with a piston rod is axially slidably arranged to divide the inner cylinder into a retraction chamber and an extension chamber in which an electrorheological fluid is contained as a pressure medium. The two chambers are connected through at least one throttle gap between the inner cylinder and an electrode tube arranged coaxially thereto. The electrode tube is surrounded coaxially by an outer tube which forms a gas pressure chamber connected with the retraction chamber through a bottom valve. Axially linear or helical seals are arranged between the inner cylinder and the electrode tube, and divide the throttle gap into at least two valve partial gaps. A throttled non-return valve opens toward the gas pressure chamber between the extension chamber and the gas pressure chamber.

Abstract: A system and method for an electromechanically actuable parking brake for motor vehicles, which is embodied as a drum brake of the “duo-servo” type. The parking brake has a brake actuating device which can be actuated by an electromechanical actuator, is designed as an expander element and acts on two brake shoes, the expander element being supported via a spring energy storage device, may be designed as a diaphragm spring assembly, and being spreadable by a predetermined length of travel, when the parking brake is actuated, to apply an application force. In order to provide a sufficiently large hot parking travel, the length of travel travelled by the expander element to apply the application force when the parking brake is actuated can be moved as a function of at least one motor vehicle state parameter.
