Path prediction for vehicular collision warning system

摘要

A motor vehicular collision warning system including a scanned beam sensor, a signal processor, and a vehicle interface system that initiates warnings to the driver or adaptively controls the vehicle. Scene data is used to predict the path of the roadway in front of a subject vehicle. Reflections from manmade and natural scene objects are extracted from the scene data to define a linear feature edge. Once the feature edge is determined, the predicted path of the subject vehicle can be determined using information regarding the vehicle trajectory and the feature edge.
