An improved method and an improved apparatus for operating an automatic door system are distinguished by the following features, inter alia: a sensor device (9) is used, which implements a monitoring region (19) assigned to and/or disposed upstream of the leaves (1; 1a, 1b) for the detection of objects (P, G) which are situated and/or moving in said monitoring region (19), by means of the sensor device (9) and/or by means of the control and/or evaluation device (11), an object (P, G) situated in the monitoring region (19) is detected with regard to the position and direction of movement of said object and also with regard to the width, size and/or contour (K) or overall contour (23) of said object, and depending on the movement-dependent position and direction of movement (21) and also the width, size and/or contour (K) or overall contour (23) of the detected object (P, G), the at least one leaf (1; 1a; 1b) is moved, in particular opened, readjusted and/or closed, in an object-related manner.

A drive device for adjusting a vehicle assembly including an electromotive adjustment drive for adjusting the vehicle assembly and a control device for controlling the adjustment drive, the control device is configured to actuate the adjustment drive in a holding mode for holding the vehicle assembly. It is provided that the control device includes a regulation module for regulating a characteristic variable of the adjustment drive and a control module, wherein the regulation module is configured to determine a correcting variable for regulating the characteristic variable of the adjustment drive in the holding mode with reference to a specified setpoint value, and the control module is configured to evaluate a change of the correcting variable to detect an adjustment request for adjusting the vehicle assembly.

In a method for operating a motor-actuatable tailgate of a motor vehicle, the motor of which can be activated or deactivated controlledly by actuation of an actuating element of an operating element, a control unit ascertains whether the actuating element is actuated for a predetermined period of time or by a predetermined actuation sequence and at the same time a manual closing movement of the tailgate is effected. If so, a holding mode is activated on reaching the tailgate position at which the actuating element is no longer actuated, wherein the motor is short-circuited in the holding mode.

A sectional door operator system for opening and closing an opening comprises a door moved between open (O) and closed (C) positions and formed by horizontal and interconnected sections. The door is connected with a door frame with frame sections on opposite sides of the opening. A drive unit system is mounted on one of the sections that moves the sectional door from the closed position (C) to the open position (O). The drive unit system comprises first and second drive units, mounted on opposite sides of the section that each have a drive motor. A sensor device is mounted on a section and connected with a control unit. The control unit controls the drive unit system at least based on sensor data. The sensor data relates to an angle () of the door in relation to a true horizontal plane of the sectional door operator system.

A vehicle has at least one flap, at least one flap drive, which is configured to open and close the at least one flap by changing a value of a state parameter of the at least one flap. A control device is configured to control the at least one flap drive in order to open the at least one flap up to an adjustable value of the state parameter of the at least one flap and to close the at least one flap. A communication device is configured to communicate wirelessly with at least one external communication device, and to periodically determine a distance of the communication device from the at least one external communication device, if a communication connection is established between the communication device and the at least one external communication device. The control device is configured to set the adjustable value of the state parameter of the at least one flap to a predetermined value of the state parameter of the at least one flap during a period in which the control device periodically determines that the distance is less than a predetermined threshold distance.
