A forward facing sensing system for a vehicle includes a windshield electronics module disposed in the vehicle cabin behind the windshield, a radar sensor device disposed within the windshield electronics module with a sensing direction forward of the vehicle, an image sensor disposed within the windshield electronics module with a viewing direction forward of the vehicle, and a control operable to analyze images captured by the image sensor in order to, at least in part, detect an object present forward of the vehicle in its direction of forward travel. The control, at least in part, determines that a potentially hazardous condition may exist in the path of forward travel of the vehicle. The radar sensor device and the image sensor collaborate in a way that enhances the sensing capability of the sensing system for the potentially hazardous condition in the path of forward travel of the vehicle.
