Реферат: The invention relates to electric equipment of a vehicle, comprising an at least partly electric braking and steering device containing an electric or electromechanical steering device (26) with or without a continuous mechanical connection between a steering wheel (28) and a steering transmission (30) and with an electronic steering controller and an electric steering adjuster (72) and containing a service brake device (124). According to the invention, an electropneumatic service brake device (124), in particular an electronic or electronically brake pressure-regulated braking system (EBS), is provided as the service brake device, containing an electropneumatic service brake valve device (1), an electronic brake controller (EBS-ECU), electropneumatic modulators (114, 116) and pneumatic wheel brake actuators (118, 120), wherein the electropneumatic service brake valve device (1) has a service brake actuating element (10) and at least one electric channel (130) with at least one electric brake value transmitter (67), which can be actuated by the service brake actuating element (10), within at least one electric service brake circuit in order to produce actuation signals dependent on an actuation of the service brake actuating element (10), at least one electronic analyzing device (FBM-ECU) which receives the actuation signals and which introduces brake requests signals into the electronic brake controller (EBS-ECU) dependent on the actuation signals, and at least one pneumatic channel (132, 134) within at least one pneumatic service brake circuit, wherein at least one control piston (12) of the service brake valve device (1) is loaded with a first actuation force by the actuation of the service brake actuating element (10) on the basis of a driver brake request, and the control piston (12) directly or indirectly controls at least one service brake valve device (1) double seat valve (34) which contains an inlet seat (64) and an outlet seat (32) in order to generate pneumatic braking pressures or brake control pressures for the pneumatic wheel brake actuators (118, 120). The means (ECU, 52) which contain the electronic analyzing device (FBM-ECU) of the electropneumatic service brake valve device (1) are designed to generate a second actuation force independent of a driver brake request, said second actuation force acting on the at least one control piston (12) in the same direction as the first actuation force or in the opposite direction thereto when a brake request is provided which is independent of the driver's request. The electropneumatic service brake device (124) is supplied with electric energy by a first electric energy source (126) or by a first energy supply circuit, which is independent of a second electric energy source (128) or a second energy supply circuit that is supplying electric energy to the electropneumatic service brake valve device (1), and the electric or electromechanical steering device (26) is provided with electric energy by the second electric energy source (128) or by the second energy supply circuit.
