1. A position determining system for determining the position of a vehicle upon entering a charging station suitable for charging an energy accumulator of the vehicle, the positioning system comprising:

  • a vehicle-side marking having at least one marking property changing in a longitudinal direction of the vehicle, wherein;

    said at least one marking property is determined by a surface profile of the marking;

    wherein said surface profile of said marking has a height that extends transversely with respect to the longitudinal direction of the vehicle, and said height changes along the longitudinal direction of the vehicle; and

    a route-side sensor device, said sensor device, as the vehicle travels past said sensor device;

    measuring a distance between said marking and said sensor device and generating a distance signal indicating said distance between said marking and said sensor device, wherein said distance extends transversely with respect to the longitudinal direction of the vehicle, andreading-out said at least one marking property in the longitudinal direction of the vehicle and generating a longitudinal vehicle direction signal indicating a position of said marking or the vehicle relative to said sensor device in the longitudinal direction of the vehicle;

    said longitudinal vehicle direction signal being generated by analyzing said distance signal.
