Electric apparatus of vehicle having an at least partly electric braking and steering device

Abstract

The invention relates to an electric apparatus of a vehicle having an at least partly electric braking and steering device comprising an electric or electromechanical steering device (26) with or without a continuous mechanical connection between a steering wheel (28) and a steering gear (30) and having an electronic steering control device and an electric steering actuator (72), and an electropneumatic service brake device (124) which comprises an electropneumatic service brake valve device (1), an electronic brake control device (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 member (10) and, within at least one electric service brake circuit, at least one electric channel (130) with at least one electric brake transducer (67) which can be actuated by the service brake actuating member (10) in order to output actuating signals in a manner which is dependent on an actuation of the service brake actuating member (10), and at least one electronic evaluation device (FBM-ECU) which receives the actuating signals and inputs brake request signals into the electronic brake control device (EBS-ECU) in a manner which is dependent on the actuating signals. The invention is characterized in that the electronic evaluation unit (FBM-ECU) is integrated into the electronic steering control device, or the electronic steering control device is integrated into the electronic evaluation device (FBM-ECU).

Description

technical field [0001] The invention relates to an electrical system of a vehicle with an at least partly electric braking and steering system according to the preamble of claim 1 and to a vehicle with an electrical system according to claim 23 . Background technique [0002] A combined and at least partially electric braking and steering device for a vehicle is known from EP 0 999 117 A2, which forms the prior art. It is provided here that in the event of a failure of a steering system component, in particular a steering actuator, individual wheels are braked in a targeted manner in order to maintain the steerability of the vehicle. As a result, fault tolerance in the event of a failure of a steering system component is improved by attempting to at least partially replace the failure of the steering system component concerned by the yaw moment generated by means of targeted braking of the individual wheels. Steering action. To increase reliability, the power supply of the...
