1. A method for operating an advance driver assistance system, the method comprising:

  • receiving a plurality of recorded routes of vehicles, each of the plurality of recorded routes including individual position indications in an order of passing during a respective journey;

    determining a lane course based on a B-spline compensation curve, wherein determining the lane course includes a processor performing the following acts;

    selecting a route from the plurality of recorded routes;

    determining, based on the selected route, a number of checkpoints to be used in generating the B-spline compensation curve, and a value of each checkpoint;

    generating a first B-spline compensation curve based on the number of checkpoints and the value of each checkpoint;

    generating a second B-spline compensation curve based on the first B-spline compensation curve and individual position indications of the plurality of routes, wherein determining the second B-spline compensation curve is independent of an order of position indications in one of the respective routes and is independent of the fact that a position indication used is assigned to a route from the plurality of routes;

    assigning the second B-spline curve as the first B-spline curve and repeating the act of generating the second B-spline compensation curve until an abort condition is satisfied;

    and when the abort condition is satisfied, assigning the second B-spline compensation curve as the lane course; and

    displaying a warning to a driver of the vehicle when it is determined by advance driver assistance system, based on the lane course, that a collision is likely.
