Abstract
A vision system of a vehicle includes a camera disposed at a vehicle and having a field of view forward of the vehicle and operable to capture image data. A vehicle-based GPS system is operable to determine a geographical location of the vehicle. A control includes an image processor operable to process image data captured by the camera. Responsive at least in part to processing of captured image data by the image processor to determine lane markings and responsive at least in part to the GPS system and responsive at least in part to map data mapping the road along which the vehicle is traveling, the control is operable to determine an enhanced estimation of the path of travel of the vehicle. The enhanced estimation may be based on reliability levels or weighting factors of the determined lane markings and the map data.
