According to the list published by the United States Trademark and Patent Office (USPTO), Apple obtained 41 technical patents yesterday, many of which are related to the Project Titan car project.
In one of the patents a lighting system for driving at night is described. Apple stated in the patent that the effective range of existing self-driving cars for detecting and classifying objects is about 60 meters. Apple hopes to expand the detection range to 200 meters by introducing a number of sensors such as near-infrared.
In the patent, Apple outlines a computer vision system for self-driving cars that can accurately identify various objects that appear within a range of 200 meters. The patent specifically mentions the efficient classification of objects appearing in the road ahead in low-light environments, thereby improving the safety of self-driving vehicles and improving the safety of self-driving cars at night.
