Electric side door drive assembly for a vehicle

An electric side door drive assembly for a vehicle, comprising:

• a length-adjustable electric actuator which is arranged between a vehicle body and a side door of the vehicle, and which is configured to facilitate opening and closing of the side door and which comprises a controllable electric motor;
• a control unit which is operationally coupled to the length-adjustable electric actuator and which is associated with a storage unit on which geometric parameters of the vehicle and operating parameters of the length-adjustable electric actuator are stored;
• and
• a door movement sensor unit which is operationally coupled to the control unit and is designed to detect stopping and a current position of the side door during opening or closing of said side door,
• wherein the control unit is designed, in the event of stopping of the side door detected by the door movement sensor unit:
• to determine whether a passive holding force of the length-adjustable electric actuator is sufficient for holding the side door at its current position;
• to determine, on the basis of side door position data provided by the door movement sensor unit, and the geometric parameters of the vehicle and the operating parameters of the length-adjustable electric actuator stored in the storage unit, a necessary current strength which is to be supplied to the controllable electric motor of the actuator in order to hold the side door in its current position;
• and
• to deliver a necessary current strength to the motor of the length-adjustable electric actuator for a holding operation.
