摘要：A system and a method are provided for calibrating a backup assist system for a trailer attached to a vehicle. The method includes driving the vehicle forward substantially straight above a threshold speed, sensing a yaw rate of the vehicle, and sensing a measured hitch angle of the trailer. A yaw sensor continuously senses the yaw rate of the vehicle and a hitch sensor continuously measures the hitch angle for determining an angle rate based on the measured hitch angle. Further, a controller determines an offset between the measured hitch angle and an actual hitch angle when the yaw rate and angle rate are substantially zero or otherwise the same.

主权项：1. A method of calibrating a backup assist system for a trailer attached to a vehicle, comprising: driving the vehicle forward substantially straight above a threshold speed; sensing a yaw rate of the vehicle; sensing a measured hitch angle of the trailer; determining an angle rate based on the measured hitch angle; and determining an offset between the measured hitch angle and an actual hitch angle when the yaw rate and angle rate are substantially zero.
