Trailer backup offset determination
First Claim
Patent Images
1. A system for calibrating a backup assist system for a trailer attached to a vehicle, comprising:
- a hitch angle sensor continuously measuring a hitch angle for determining a hitch angle rate;
anda controller configured to determine an offset of the measured hitch angle when the vehicle is driving forward and rearward above a threshold speed and the hitch angle rate is substantially zero and prioritize the driving rearward offset over the driving forward offset.
