A computer-implemented method for detecting a wide turn maneuver of a vehicle travelling on a road segment ahead of an ego-vehicle which is travelling on a known ego-lane of the same road segment, the wide turn maneuver being a right turning maneuver starting outside the rightmost lane or the wide turning maneuver being a left turning maneuver starting outside the leftmost lane, the method is performed on the ego-vehicle or from the perspective of the ego-vehicle and the method comprising - detecting a turn signal status of the vehicle, wherein the turn signal status describes whether the left turn signal only, the right turn signal only, both the left turn signal and the right turn signal or none of the turn signals is/are activated, - detecting a lane status of the vehicle, wherein the lane status describes a lane of the road segment on which the vehicle is travelling, - receiving a turn distance information describing a distance to an upcoming turn and comparing the turn distance information to a turn distance threshold, - determining that the vehicle is performing the wide turn maneuver, o if the turn signal status describes that the left turn signal only is activated and the lane status describes that the vehicle is travelling on a lane being located on the right of the ego-lane and the turn distance information is inferior to the turn distance threshold, or o if the turn signal status describes that the right turn signal only is activated and the lane status describes that the vehicle is travelling on a lane being located on the left of the ego-lane and the turn distance information is inferior to the turn distance threshold. - detecting a turn signal status of the vehicle, wherein the turn signal status describes whether the left turn signal only, the right turn signal only, both the left turn signal and the right turn signal or none of the turn signals is/are activated, - detecting a lane status of the vehicle, wherein the lane status describes a lane of the road segment on which the vehicle is travelling, - receiving a turn distance information describing a distance to an upcoming turn and comparing the turn distance information to a turn distance threshold, - determining that the vehicle is performing the wide turn maneuver, o if the turn signal status describes that the left turn signal only is activated and the lane status describes that the vehicle is travelling on a lane being located on the right of the ego-lane and the turn distance information is inferior to the turn distance threshold, or o if the turn signal status describes that the right turn signal only is activated and the lane status describes that the vehicle is travelling on a lane being located on the left of the ego-lane and the turn distance information is inferior to the turn distance threshold. o if the turn signal status describes that the left turn signal only is activated and the lane status describes that the vehicle is travelling on a lane being located on the right of the ego-lane and the turn distance information is inferior to the turn distance threshold, or o if the turn signal status describes that the right turn signal only is activated and the lane status describes that the vehicle is travelling on a lane being located on the left of the ego-lane and the turn distance information is inferior to the turn distance threshold.
