The present invention relates to a door operator and a method for set up of a door operator (1) comprising a drive unit (7), a user interface (8) and a control unit (9), which control unit (9) controls the value of the current applied to the drive unit (7) such that the door operator (1) employs a first speed trajectory corresponding to the value of the current when opening and/or closing a door leaf (2) connected to the door operator (1), the method comprising the steps of: detecting a first or a second mode of set up of the control unit (9), and in the first mode, receiving a value of the time for opening and/or closing the door leaf (2) from the user interface (8), calculating a value of the current that should be applied to the drive unit (7) during acceleration and braking to obtain said value of the time for opening and/or closing the door leaf (2), and setting the calculated value of the current in the control unit (9), such that the door operator (1) employs the first speed trajectory when opening and/or closing a door leaf (2) connected to the door operator (1) corresponding to said set value of the time, in the second mode receiving a value of the current that should be applied to the drive unit (7) when opening and/or closing the door leaf (2) from the user interface (8), setting the value of the current in said control unit (9) that should be applied to the drive unit (7) during acceleration and braking such that the door operator (1) employs the first speed trajectory when opening and/or closing a door leaf (2) connected to the door operator (1) corresponding to said set value of the current.

A system and method are provided for detecting blockages during an automatic adjustment of a movable vehicle part in a motor vehicle equipped with an electric motor drive and an electronic control unit. The drive current as well as the movement speed of the drive are detected by the electronic control unit. When the movement speed increases above the normal level, the control unit suppresses the detection of a blockage event if a drive current increase required for the movement speed increase cannot be ascertained.

An apparatus for controlling bus doors (14, 16) that are arranged as a pair of doors that move in coordinated relation between door open positions and door closed positions, enables passengers to access an interior area (12) of a bus (10). The apparatus includes an actuator (28, 226). The actuator includes a drive lever (34, 228) that is selectively rotationally movable between rotational positions in which both of the doors are in the open positions and in the closed positions. Exemplary arrangements include at least one controller (128) that is operative to prevent the doors from causing damage to or from being damaged by engagement with obstructions. The controller further enables a bus driver or other authorized user to control access to the interior area of the bus using a user mobile device (144).

An open-roof assembly for a vehicle roof comprises a moveably arranged closure member, a drive assembly for moving the closure member and a control unit operatively coupled to the drive assembly. The control unit comprises a pinch detection unit for detecting a pinch of the closure member with an object. The pinch detection unit comprises a first pinch detection system and a second pinch detection system. The first pinch detection system is configured to detect a pinch with a soft object and the second pinch detection system is configured to detect a pinch with a hard object. The pinch detection unit is configured to adapt a configuration setting of the first pinch detection system upon detection of a pinch with a hard object by the second pinch detection unit to configure the first pinch detection system to detect a pinch with said hard object.

A door closer with an electric motor-assisted closing feature, that may generate its own power to assist in closing, and controls the speed of opening and closing of the door during generation is disclosed. Embodiments of the present disclosure are realized by a motorized door closer that electrically creates a latch boost force for a closing door. The door closer includes a motor disposed to operatively connect to a door so that the door will be moved toward closed when the motor moves, and a position sensor to determine a position of the door. A processor is programmed to exert a closing force on the door in the latch boost region or when it otherwise detects that a motor assist is needed.

A moving body control device includes a pinching detecting unit. The pinching detecting unit is configured to calculate a first difference between physical quantities at a beginning and an end of a first period, calculate a plurality of second differences for respective second periods obtained by dividing the first period, each of the differences being a difference between physical quantities at a beginning and an end of the corresponding second period, and determine that pinching of an object has occurred in a case in which the first difference is equal to or greater than a first threshold value and a ratio of second differences equal to or greater than a second threshold value to the plurality of the second differences is equal to or greater than a third threshold value.

An opening and closing control device includes a motor configured to drive, in an opening and closing direction, an opening and closing body that is supported a vehicle body and allowed to be opened and closed, a controller configured to control the motor, and a pulse encoder configured to output a pulse signal. The controller adjusts an advance angle of the motor, detects a rotational speed of the motor or an opening and closing speed of the opening and closing body according to pulse detection based on the pulse signal output from the pulse encoder, and detects a pinching state of the opening and closing body when the rotational speed of the motor or the opening and closing speed of the opening and closing body is equal to or less than a threshold value during advance angle control on the motor.

A moving body control device controls a moving body that moves by a rotation of a motor. The moving body control device includes: a pinching detecting unit that detects pinching of an object based on a change in a physical quantity indicating a rotation state of the motor. The pinching detecting unit is configured to: determine that the pinching has occurred in a case in which a first difference of the physical quantity in a first period is equal to or greater than a first threshold value and a tendency of a change in the physical quantity in the first period is a monotonous increase or a monotonous decrease; and lower a value of the first threshold value in a case in which the tendency of the monotonous increase or the monotonous decrease of the physical quantity continues for a period longer than the first period.
