First Claim
Patent Images
1. A system for calibrating a backup assist system for a trailer attached to a vehicle, comprising:
- a hitch sensor continuously measuring a hitch angle between the vehicle and the trailer; and
a controller configured to determine an offset of the measured hitch angle, wherein the controller is configured to calculate and store in memory a forward offset if no reverse offset is stored, wherein the controller is further configured to not calculate a forward offset if the reverse offset is stored.

-
a hitch sensor continuously measuring a hitch angle between the vehicle and the trailer; a controller configured to determine an offset of the measured hitch angle, wherein the controller is configured to calculate and store in memory a forward offset if no reverse offset is stored; and a knob sensor continuously sensing a knob angle, wherein the knob angle is substantially zero when the vehicle and trailer are in a substantially standing state, and wherein the reverse offset is determined when the knob angle is substantially zero over a threshold time while the vehicle is driving above a threshold speed. - View Dependent Claims (8, 9, 10, 11, 12)
