Patent attributes
Disclosed are systems that include a controller circuit in communication with a ranging sensor configured to detect objects proximate to a host vehicle. In an aspect, the controller circuit is configured to perform a first detection count of the detected objects, determine a first group of objects of the detected objects, determine a first distance to the first group of objects, utilize the first distance to determine a trailer distance between the host vehicle and a front of a trailer, determine a second group of objects of the detected objects, determine a second distance to the second group of objects, utilize the second distance to determine an axle distance between the front of the trailer and a trailer axle, and determine a trailer length based on the trailer distance and the axle distance. Methods are also disclosed.
