A method for transmitting data via a traction current conductor which simultaneously conducts drive current for a vehicle and in which an interruption in the data transmission by an arc cccurring between a vehicle-end drive current collector and the traction current conductor is reliably avoided. The method for trandsmitting data via a traction current conductor, in which at the transmitter end at least two data signals including in each case the data in an identical form are fed into the traction current conductor with different frequency channels. In the event of an arc occurring at the receive end, the received data of that data signal or those data signals whose amplitude does not drop below a ratio necessary for achieving a specific bit error probability with respect to the amplitude of the interference signal S(f), is selected for evaluation.

Method for transmitting data via a traction control which carries an electrical driving current for vehicles

The invention relates to a method for transmitting a control signal to a vehicle which is driven using an electrical drive current which is fed into a traction current conductor at a drive current feed point. In order to ensure that the transmission of the control signal is very largely unaffected by interference frequency components included in the drive current, according to the invention one current sensor, which is located outside the line section, is used to receive the control signal.
