A steering control unit and to a method of controlling the steering of a multi-unit vehicle is provided, the vehicle having a plurality of vehicle parts movably connected to one another and a plurality of steerable axle units. A first axle control unit is in conjunction with a first steerable axle unit and at least one second axle control unit is in conjunction with at least one second steerable axle unit. The steering control system has a central control module that is connected to the axle control units via a common data line for exchange of steering angle data. The axle control units have data interfaces for communication via the data line. The data interfaces transfer mutually identical data formats, whereby the steering control system is set up in a modular manner with a variable number of axle control units that can be integrated.

Steering control system of a multi-unit vehicle

An air passenger bridge with a coupling module for coupling to an aircraft, wherein the coupling module has a floor device. The floor device has a front edge, whereas said floor device with said front edge can be traveled towards a fuselage of an aircraft in a region below an aircraft door, and wherein a safety device is configured to avoid a collision of the floor device with the aircraft door. The safety device has at least one contactlessly acting proximity sensor that is integrated in the floor device.

An articulated vehicle has a joint between the vehicle parts. The joint includes two joint segments that are rotatable relative to each other. The joint includes a damping device configured in such a manner that in any angular position of the joint segments, the damping torque acting on the joint is substantially the same in a positive as well as in a negative direction of rotation at the moment of a reversal of the direction of rotation.

A hydraulic system for damping the motion of rotation of a swivel joint between two vehicle parts of an articulated vehicle, of an articulated bus for example, comprising a hydraulic damping device as well as an electrically triggerable proportional pressure control valve, whereas the proportional pressure control valve is arranged between the force side and the suction side of the damping device, a mechanical pressure control valve ( ) being provided in addition to the proportional pressure control valve ( ) in the conduit between the suction side and the force side of the damping device, and whereas a multiple-way valve is provided for the alternative drive of the pressure control valve ( ) or of the proportional pressure control valve ( ).
