Abstract
Method and apparatus for determination of positions of a moving object on the basis of a selection and storing a current position (Px) as a waypoint (Wx) if the following criteria are fulfilled: (1) the current distance (Dx) of the position (Px) along the road from the previous waypoint (Wx−1) is greater than a first parameter X; OR (2a) the current distance (Dx) of the position (Px) along the road from the previous waypoint (Wx−1) is greater than a second parameter Y, wherein Y<X, AND (2b) the deviation (Ax) between the current traveling direction of the object and the direction established by the connection of the last two waypoints (Wx−1, Wx−2) is greater than a third parameter Z, AND (2c) the speed of the object is greater than a minimum speed S. The stored waypoints allow a determination of the traveling direction which is advantageous for localization of vehicles driving on parallel one-way lanes.
