Device for driving a flap

Abstract

A device (14) for selectively driving a flap (12) of a motor vehicle (10), comprising a control device (16) for controlling a drive unit (18) by which the flap (12) can be driven, braked, or locked. The device (14) comprises a sensor system for monitoring at least one detection area (24, 28), and the control device (16) is designed to control the drive unit (18) depending on the state of the monitored detection area (24, 28). The drive unit (18) comprises an electric drive, in particular an electric motor, and the control device (16) is designed to determine a distance of an object relative to the sensor system, in particular relative to the flap (12), and to control the drive unit (18) depending on the determined distance to track the flap (12). The object is a hand of a user of the device (14).that the control device (16) is designed to determine a position of the object relative to the sensor and to control the drive unit (18) depending on the determined position, wherein a specific command is assigned to a specific position range, and the control device (16) is designed to monitor the detection range (24, 28) at predetermined time intervals, wherein the predetermined time intervals are variable depending on an opening position and / or a drive speed of the flap (12) and / or depending on a monitoring result.
