Abstract

A vehicular trailering system includes a plurality of cameras disposed at a vehicle, and a control having an image processor that processes image data captured by the plurality of cameras. With a trailer hitched to the vehicle, the system determines trailer angle of the trailer relative to the vehicle responsive at least in part to processing of image data captured by at least some of the cameras during forward motion of the vehicle. With the cameras disposed at the vehicle and with the trailer hitched to the vehicle and responsive at least in part to processing of image data captured by at least some of the cameras during forward motion of the vehicle, an object exterior of the vehicle is detected. Responsive to detection of the detected object, the system plans a path of forward travel of the vehicle towing the trailer that avoids contact with the detected object.

10. The vehicular trailering system of claim 1, wherein the detected object is a pedestrian.

11. The vehicular trailering system of claim 10, wherein, responsive at least in part to processing by said image processor of image data captured by at least said forward viewing camera, said vehicular trailering system distinguishes a moving pedestrian from a static pedestrian.

12. The vehicular trailering system of claim 10, wherein, responsive at least in part to processing by said image processor of image data captured by at least said forward viewing camera determining that a moving pedestrian stops, said vehicular trailering system changes the planned path of forward travel of the vehicle towing the trailer to avoid contact with the stopped pedestrian.

13. A vehicular trailering system, said vehicular trailering system comprising:

a plurality of cameras disposed at a vehicle and having respective fields of view exterior of the vehicle;

said plurality of cameras comprising a forward viewing camera disposed at the in-cabin side of a windshield of the vehicle, said forward viewing camera viewing forward of the vehicle through the windshield;
