First Claim
Patent Images
1. A device for estimating a trailer length, comprising:
- a processor in communication with a wheel steer angle sensor and a hitch angle sensor, the processor operable to;
determine a ratio between a wheel steer angle and a hitch angle;
generate a running average of the ratio; and
calculate the trailer length based on an average ratio between the wheel steer angle and the hitch angle.

Abstract
A vehicle system for estimating a trailer length is disclosed and includes a first sensor for measuring a wheel steer angle and a second sensor for measuring a hitch angle. A processor is in communication with the at least one sensor and is operable to determine a ratio between the wheel steer angle and the hitch angle, generate a running average of the ratio, and calculate the trailer length based on an average ratio between the wheel steer angle and the hitch angle.
