TRAILER LENGTH ESTIMATION IN HITCH ANGLE APPLICATIONS

摘要

A vehicle system for estimating a trailer length is disclosed. The system incorporates at least one sensor configured to measure a wheel steer angle and a trailer angle in communication with a processor. The processor is operable to determine a first length by a first computation method and determine a second length by a second computation method. The processor is further operable to validate an estimated trailer length based on the first length and the second length and perform a back-up function for the trailer based on the estimated trailer length.

主权项

1. An apparatus for determining an estimated trailer length comprising:
a processor operable to:
determine a first length having a first uncertainty;determine a second length having a second uncertainty;compare the first length to the second length in a first comparison; andset the estimated trailer length to the first length based on the first comparison yielding a result less than a first predetermined value.
