Abstract
A vehicular driving assist system includes a camera disposed at a vehicle. The vehicular driving assist system, at least in part processing of image data captured by the camera, determines a target path of travel ahead of the vehicle. The vehicular driving assist system determines vehicle state information from a respective vehicle state source of a plurality of vehicle state sources of the vehicle based at least in part on a current environmental condition at the vehicle The vehicular driving assist system estimates curvature of a current trajectory of travel of the vehicle based at least in part on the determined vehicle state information.
