Abstract

Method (400) and control unit (310) in a vehicle (100) for estimating a stretch of a road (120), based on a set of tracks (130) of another vehicle (140), when driving the vehicle (100) along the road(120) in a driving direction (105) to a destination (200). The method (400) comprises: detecting (401) a set of tracks (130) of the other vehicle (140), on the road (120); estimating (402) the geographical position of the detected (401) set of tracks (130); comparing (404) the estimated (402) geographical position of the detected (401) set of tracks (130) with map data; rejecting (407) the detected (401) set of tracks (130) when it exits the road (120) to the destination (200) or when situated in a driving lane in a direction opposite to the driving direction (105); and otherwise estimating (408) the stretch of the road (120) based on the set of tracks (130).

Description

technical field [0001] This document discloses a method and a control unit. More specifically, a method and control unit are disclosed for estimating the extent of a road based on a set of tire trajectories of another vehicle while driving a vehicle along the road. Background technique [0002] Recently developed vehicles can follow roads or traffic lanes by detecting road markings and using them to position the vehicle sideways on the road when the vehicle is an autonomous vehicle or a manned vehicle driving in an autonomous mode. [0003] A vehicle may include a vehicle for navigating on a road, such as a truck, car, motorcycle, trailer, bus, bicycle, terrain vehicle, tractor, or other similar manned or unmanned vehicle. [0004] Where the vehicle has a driver, a lane departure warning (LDW) system can warn the driver when road markings are crossed. [0005] Such warning systems typically include cameras that detect road markings on the road, and through image recognitio...
