The controller is configured to determine a current operational state of the entrance system among a plurality of possible operational states, and selectively cause at least one of the sensors to be in its active mode or in its inactive mode depending on the determined current operational state of the entrance system.

A method for operating a door system having a movable door leaf and a control unit, with at least one sensor unit being configured, with which the approach of at least one person is detected, includes: providing the sensor unit in the form of a radar sensor and/or a camera with an image processing unit; recording a distance of the person from the door system using the sensor unit; recording an approach speed with the sensor unit, at which the person approaches the door system; transmitting the distance and approach speed; determining a probable approach time of the person with the control unit; determining the movement parameters for moving the door leaf by the control unit and actuating the door leaf by the door actuator based on the movement parameters determined by the control unit. A door system having a control unit is configured to carry out this method.

A method for the operation of a motorized flap arrangement of a motor vehicle, wherein the flap arrangement has a flap which is pivotable with respect to a motor vehicle body, wherein the flap arrangement has a back-driveable drive arrangement for the motorized adjustment of the flap and a control arrangement for controlling the drive arrangement. It is proposed that an, in particular gravitationally induced, predetermined flap deflection is detected by means of the control arrangement from a de-energized intermediate position of the flap in a monitoring routine and, in response to the detection of the predetermined flap deflection, a holding routine is triggered in which the drive arrangement is adjusted to a flap-holding position in a holding control circuit.

An automatic door operator is disclosed, including a main control circuit, an actuating unit configured to output torque, and a transmission device. The main control circuit controls operation of the actuating unit to drive a movement of a door leaf through the transmission device. The automatic door operator further includes: a DC power supply configured to supply a DC voltage VDD to the main control circuit; and a standby power switching circuit, connected in series between the DC power supply and the main control circuit, and configured to acquire a switching signal and conduct, or cut off after a preset time period Δt has been elapsed, electric current between the DC power supply and the main control circuit according to the switch signal. A method for driving the automatic door operator is also disclosed. The present disclosure realizes the purpose of saving energy and electricity of the automatic door operator, while increasing the lifetime of the main control circuit.

Methods and systems are provided for an automated door system for a vehicle. In one example, the automated door system may include a set of manual actuating devices and a set of hands-free actuating devices for automatically unlocking and opening the doors of a commercial vehicle used for transporting cargo. The manual and hands-free actuating devices may be used in response to the operating state of the vehicle.

A control arrangement (20) for an entrance system (10) has one or more movable door members (D1 . . . Dm) and an automatic door operator (30) for causing movements of the one or more movable door members (D1 . . . Dm) between closed and open positions. The control arrangement (20) comprises a controller (32) and a plurality of sensors (S1 . . . Sn). Each sensor is connected to the controller (32) and is configured to monitor a respective zone (Z1 . . . Zn) at the entrance system (10) for presence or activity of a person or object. Each sensor (S1 . . . Sn) has an active mode and an inactive mode, wherein the sensor consumes no electric power in the inactive mode or substantially less electric power in the inactive mode than in the active mode. The controller (32) is configured to determine a current operational state of the entrance system (10) among a plurality of possible operational states, and selectively cause at least one of the sensors (S1 . . . Sn) to be in its active mode or in its inactive mode depending on the determined current operational state of the entrance system (10).

A vehicle door assembly including a vehicle door pivotally arranged on a vehicle body, a force-transmitting device for adjusting and/or fixing the vehicle door relative to the vehicle body, wherein the force-transmitting device includes a transmission element for producing a flux of force between the vehicle door and the vehicle body in order to adjust the vehicle door relative to the vehicle body or hold it in position relative to the vehicle body, and a control device for controlling the force-transmitting device.
