Abstract
A system for calibrating a backup assist system for a trailer attached to a vehicle is provided which includes a hitch sensor continuously measuring a hitch angle between the vehicle and the trailer. A controller is configured to determine an offset of the measured hitch angle. The controller is configured to calculate and store in memory a forward offset if no reverse offset is stored.

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 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;
- 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.
