The vehicular vision system of claim 10, wherein, responsive at least in part to image processing of captured image data, said vision system is operable to identify a trailer at the vehicle via identification of a trailer code element of the trailer that is viewable by said camera. 12. The vehicular vision system of claim 11, wherein said trailer code element comprises a target having a Barker code pattern established thereon. 13. A vehicular vision system, said vehicular vision system comprising: a camera disposed at a vehicle and having an exterior field of view rearward of the vehicle, wherein said camera is operable to capture image data;an image processor operable to process captured image data;wherein, when the vehicle is towing a trailer, and based at least in part on image processing of image data captured by said camera during maneuvering of the vehicle and the trailer, said image processor (i) estimates a distance between a hitching point of the trailer and an axle of the trailer, and (ii) estimates a length of the trailer that includes the estimated distance between the hitching point of the trailer and the axle of the trailer and an estimated distance between the axle of the trailer and a rear end portion of the trailer;wherein image data captured by said camera during maneuvering of the vehicle and the trailer includes image data captured by said camera when the vehicle is maneuvered with the trailer at an angle relative to the vehicle;wherein said vision system, responsive at least in part to image processing of captured image data, is operable to determine a trailer angle of the trailer that is towed by the vehicle;wherein said vision system is operable to determine a path of the trailer responsive to a steering angle of the vehicle and the determined trailer angle of the trailer and the estimated length of the trailer, and wherein said vision system is operable to display information for viewing by a driver of the equipped vehicle to assist the driver in driving the vehicle with the trailer;wherein said vision system is operable to display images of a road in the direction of travel of the vehicle and the trailer and wherein said vision system is operable to display an overlay to indicate to the driver of the vehicle a steering path for the vehicle;wherein said overlay comprises markers that indicate a determined path of travel of the front wheels of the vehicle and a path of travel that the wheels of the trailer will follow if the driver of the vehicle steers the front wheels of the vehicle along the determined path of travel of the front wheels; andwherein at least one of (i) said vision system displays images of a road in the forward direction of travel of the vehicle and the trailer and wherein said overlay indicates a steering path for the vehicle that tows the trailer around an obstacle and (ii) said vision system displays images of a road in the rearward direction of travel of the vehicle and the trailer and wherein said overlay indicates a steering path for the vehicle to drive the trailer into a selected location. 14.
