Patent attributes
Embodiments of systems and methods for operating a power tailgate system are disclosed. A vehicle includes a rotatable element structured for operable connection with, and disconnection from, a tailgate when the rotatable element resides in a predetermined tailgate removal orientation. A motor is connected with the rotatable element for interdependent movement, and a motor circuit is provided for the motor. During a driving event, the system identifies when no tailgate is connected with the rotatable element. If no tailgate is connected with the rotatable element, the system determines if the rotatable element resides in the predetermined tailgate removal orientation. If the rotatable element resides in the predetermined tailgate removal orientation, the system may check the rotatable element against rotation during the driving event by operating a motor circuit to electrically brake the motor to prevent the rotatable element from rotating out of the predetermined tailgate removal orientation.
