A road-guided motor vehicle includes a power collector for an overhead line and an actuator arrangement. The power collector is controlled by the actuator arrangement from a first, pantograph-lowered into a second, pantograph-raised position or vice versa. The power collector is assigned a sensor arrangement having a data connection to a control unit of the actuator arrangement. The control unit is configured such that a contact pressure of power collector against overhead line is detected or determined using sensor arrangement data, a memory with spatially resolved contact pressures for the power collector and a position ascertaining unit. At a motor vehicle position determined by the position ascertaining unit, an associated contact pressure is read out from the memory and automatically set by the control unit or signaled to a motor vehicle driver. A method for raising a power collector pantograph onto an overhead line is also provided.

A vehicle is provided that comprises two or more radio frequency (RF) antennas and two or more RF transceivers to communicate wirelessly sensitive information associated with a user of the vehicle (the two or more RF antennas being at different physical locations on an exterior of the vehicle). The vehicle determines which one of the two or more RF antennas is receiving a strongest signal from a common signal source, selects a first RF transceiver associated with the RF antenna with the strongest signal to send the sensitive information associated with the user to the common signal source, and sends the sensitive information associated with the user to the first RF transceiver for transmission to the common signal source.

A rocker for a current collector of a vehicle includes at least one first contact strip connected to a first lever arrangement which is coupled to a first bearing device, and connected to a second lever arrangement which is coupled to a second bearing device, wherein the first bearing device and the second bearing device are connectable in an articulated manner to a current collector linkage, where a first torsion spring is fixedly connected to a lever of the first lever arrangement and non-rotatably via a displaceable bearing to the first bearing device or is connected non-rotatably via a displaceable bearing to a lever of the first lever arrangement and fixedly to the first bearing device, where the first torsion spring simultaneously forms a torque transmission device and a spring device such that a lightweight, compact and nevertheless robust arrangement for collecting current is thereby obtained.

A method and a device test whether there is contact between a current collector and a contact wire of an overhead line. The current collector is located on a motor vehicle driven by an electric motor, and the contact wire extends in a direction of travel. The current collector has two contact regions oriented transversely to the direction of travel which are arranged one behind the other in the direction of travel and on each of which an end contact element is located. A pair of end contact elements located on the same side is connected to a measuring device and an electrical state variable is detected by the measuring device. Subsequently, it is determined in accordance with the detected state variable whether the pair of end contact elements is in contact with the overhead line.
