Abstract
An assistance system for a road vehicle which can be used on a roadway having one or more lanes, includes a position determination system for determining a lateral relative position of the road vehicle on the roadway. The position determination system has an electrical signal line disposed parallel to the roadway, a signal generator for generating and feeding an electrical signal into the signal line, resulting in a current flow which can be generated in the signal line, an on-vehicle sensor assembly for capturing a field strength and/or a field direction of an electromagnetic field forming about the signal line as a result of the current flow generated, and an on-vehicle evaluation unit, configured to determine, from the captured field strength and/or field direction, a lateral relative position of the road vehicle relative to the signal line. A more reliable position determination system is thus provided.
