Abstract
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.
