Li doesn’t explicitly teach wherein the rearward-viewing camera comprises a CMOS imaging array having at least one million photosensors arranged in rows and columns.
However Rachor, in the same field of endeavor, teaches wherein the rearward-viewing camera comprises a CMOS imaging array having at least one million photosensors arranged in rows and columns (Rachor: Para. 4, 40; driving assistance system for a vehicle that utilizes one or more sensors such as imaging sensors or cameras (preferably one or more CMOS cameras); at least 1 million photosensor elements).
It would have been obvious to one having ordinary skill in the art to modify the autonomously coupling tow vehicle to a trailer (Li: Para. 28) with a rearview CMOS camera (Rachor: Para. 4) with a reasonable expectation of success because a driving assistance system is improved by a CMOS to capture data representative of objects and scenes exterior of the vehicle (Kim: Para. 4).
Li and Rachor don’t explicitly teach wherein the vehicular trailer hitching assist system, responsive to the determined position of the trailer coupler relative to the bed of the pickup truck being exterior the bed of the pickup truck and responsive to the determined height of the trailer coupler relative to the hitch of the pickup truck being less than or equal to a first threshold amount, generates a first trailer height adjustment signal for a trailer height adjustment system of the trailer, and wherein, responsive to the first trailer height adjustment signal, the trailer height adjustment system of the trailer is operated to adjust the height of the trailer coupler until the determined height of the trailer coupler relative to the hitch of the pickup truck is greater than the first threshold amount; ………….. generates a second trailer height adjustment signal for the trailer height adjustment system of the trailer; wherein, responsive to the second trailer height adjustment signal, the trailer height adjustment system of the trailer is operated to adjust the height of the trailer coupler until the determined height of the trailer coupler relative to the hitch of the pickup truck is less than or equal to the second threshold amount.

It would have been obvious to one having ordinary skill in the art to modify the autonomously coupling tow vehicle to a trailer (Li: Para. 28) with a rearview CMOS camera (Rachor: Para. 4), and a trailer height adjustment control (Simmons: Para. 91) with a reasonable expectation of success because wirelessly sending and automatic hitching command to the trailer allows the trailer to raise or lower the trailer coupler to the desired height for vehicle alignment and hitching (Simmons: Para. 8, 91).
Li, Rachor, and Simmons don’t explicitly teach determined based at least in part on processing at the ECU of image data captured by the rearward-viewing camera.
However Niewiadomski, in the same field of endeavor, teaches determined based at least in part on processing at the ECU of image data captured by the rearward-viewing camera (Niewiadomski: Para. 39, 45; vision processing, the imaging system includes a camera mounted on vehicle in a position to capture the fifth-wheel hitch; detected rotation point 28 can be compared to the location of the rear vehicle axle during execution of the hitch angle routine to update the drawbar length L on an ongoing basis).
It would have been obvious to one having ordinary skill in the art to modify the autonomously coupling tow vehicle to a trailer (Li: Para. 28) with a rearview CMOS camera (Rachor: Para. 4), a trailer height adjustment control (Simmons: Para. 91), and distance calculations from the rearview camera (Niewiadomski: Para. 39, 45) with a reasonable expectation of success because continuous distance calculation is needed when a vehicle with a trailer have a continuously moving rotation point (Niewiadomski: Para. 45).
Regarding claim 21, Li teaches the vehicular trailer hitching assist system of claim 20, wherein the vehicular trailer hitching assist system determines the height of the trailer coupler relative to the hitch of the pickup truck by comparing height of the trailer coupler to height of the hitch of the pickup truck (Li: Para. 49; determining a relative height between a top portion of the hitch ball of the tow vehicle and a bottom portion of the hitch coupler of the selected trailer and determines if the hitch coupler can releasably receive the hitch ball based on the relative height).
Regarding claim 23, Li teaches the vehicular trailer hitching assist system of claim 21, wherein, with the position of the trailer coupler relative to the bed of the pickup truck being exterior the bed of the pickup truck, the vehicular trailer hitching assist system determines the height of the trailer coupler relative to the hitch of the pickup truck by determining height of the trailer coupler relative to a ground surface and comparing the determined height of the trailer coupler to the height of the hitch of the pickup truck (Li: Para. 49; determining a relative height between a top portion of the hitch ball of the tow vehicle and a bottom portion of the hitch coupler of the selected trailer and determines if the hitch coupler can releasably receive the hitch ball based on the relative height).

However Bochenek, in the same field of endeavor, teaches wherein the vehicular trailer hitching assist system determines the height of the hitch of the pickup truck via image processing at the ECU of image data captured by the rearward-viewing camera (Bochenek: Col. 3 Lines 27-40; the controller can determine a hitch height of the hitch and a coupler height of the coupler relative to the ground).
It would have been obvious to one having ordinary skill in the art to modify the autonomously coupling tow vehicle to a trailer (Li: Para. 28) with a rearview CMOS camera (Rachor: Para. 4), a trailer height adjustment control (Simmons: Para. 91), and distance calculations from the rearview camera (Niewiadomski: Para. 39, 45) and the height comparison of the hitch and the coupler relative to the ground based on the rearview image (Bochenek: Col. 3 Lines 27-40) with a reasonable expectation of success because warning the driver when the hitch may crash into the coupler by image height comparison allows the already present rearview camera to aid the driver in a hitching or unhitching process (Bochenek: Col. 3 Lines 27-40).
Claim 24 is rejected under 35 U.S.C. 103 as being unpatentable over Li et al. (US Publication 2018/0251153 A1) in view of Rachor (US Publication 2018/0370527 A1), Simmons et al.

Regarding claim 24, Li, Rachor, Simmons, and Niewiadomski don’t explicitly teach wherein the rearward- viewing camera is disposed at a center high-mounted stop lamp (CHMSL) of the pickup truck.
However Diessner, in the same field of endeavor, teaches wherein the rearward- viewing camera is disposed at a center high-mounted stop lamp (CHMSL) of the pickup truck (Diessner: Para. 12; a second rearward viewing camera that is disposed at a center high mounted stop lamp (CHMSL) location at the vehicle)
It would have been obvious to one having ordinary skill in the art to modify the autonomously coupling tow vehicle to a trailer (Li: Para. 28) with a rearview CMOS camera (Rachor: Para. 4), a trailer height adjustment control (Simmons: Para. 91), and distance calculations from the rearview camera (Niewiadomski: Para. 39, 45), and a rearward center high mount stop lamp (Diessner: Para. 12) with a reasonable expectation of success because rearward viewing cameras used in autonomously maneuvering a vehicle in reverse and aligning the tow ball with the trailer hitch improve an automatic trailer hitching (Diessner: Para. 17).
