Abstract:
1. A method for selecting an anchor lane in a vehicle lane tracking system, said method comprising: predicting lane information for a vehicle using digital map data, including determining whether an exit or entrance lane is present; using a controller to predict lane information for the vehicle using leading vehicle trajectory data; obtaining from a vision system at least one of left lane marker data and/or right lane marker data; performing a lane curvature fusion calculation using the digital map data, the leading vehicle trajectory data and the lane marker data from the vision system, where the lane curvature fusion calculation is performed on a microprocessor in the vehicle lane tracking system; comparing the lane marker data from the vision system to the digital map data and the leading vehicle trajectory data; and selecting an anchor lane for tracking based on whether the exit or entrance lane is present and the comparison of the lane marker data from the vision system to the digital map data and the leading vehicle trajectory data.
