Electric equipment of a vehicle, comprising an at least partly electric braking and steering device with high availability

Abstract

A braking system and a method of operating such a braking system are provided for a vehicle having at least partly electric braking, a steering device containing an electric or electromechanical steering device, an electronic steering controller and an electric steering adjuster and containing a service brake device. The system includes an electropneumatic service brake device containing an electropneumatic service brake valve device, an electronic brake controller, electropneumatic modulators, pneumatic wheel brake actuators, a service brake actuating element, and at least one electric channel () with at least one electric brake value transmitter which senses activation of the service brake actuating element. The at least one electric brake value transmitter produces actuation signals which are relayed to the electronic brake controller. The electronic brake controller causes a first actuation force to be applied to at least one control piston of the service brake valve device to control at least one double seat valve of the service brake valve device to generate pneumatic braking pressures or brake control pressures for the pneumatic wheel brake actuators. The electronic controls are further configured to generate a second actuation force on the at least one control piston when a brake request independent of the driver's request exists, independent of a driver brake request. The electropneumatic service brake device is supplied with energy independently from energy supplied to the electropneumatic service brake valve device and the electric or electromechanical steering device.
