An actuation system and method of operation for moving a closure panel in one of a normal drive state and a back drive state are provided. The actuation system includes a mechanical coupling for moving the closure panel. A motor with a shaft is directly and operably connected to the mechanical coupling to directly move the mechanical coupling.

Embodiments of a system for controlling a vehicle power tailgate are described. The system includes a motor operably connectible to a tailgate to open and close the tailgate, a processor, and a memory communicably coupled to the processor. The memory stores a tailgate control module including instructions that when executed by the processor cause the processor to, responsive to a value of a motor speed parameter being above a predetermined motor speed threshold and a value of a motor acceleration parameter being above a predetermined motor acceleration threshold during opening of a tailgate, control operation of the motor to apply a braking force to the tailgate.

A method for operating a flap assembly of a motor vehicle, a drive assembly for the motorized adjustment of the flap, a motor vehicle lock, and a flap sensor assembly for identifying a flap position, wherein the drive assembly has at least one drive which is restorably movement-coupled to the flap, with an electric drive motor, wherein the motor vehicle lock fixes the flap in a closed position in a main locked state, wherein the drive motor is activated by a drive control system of the drive assembly depending on the identified flap position. It is proposed that when the identified flap position reaches a predetermined braking initiation position situated before an end position in a movement procedure of the flap, the drive motor is activated in a braking routine by the drive control system in such a way that the drive assembly produces a motorized braking effect.
