Abstract:
Die erfindungsgemäße Blockiererkennung bei automatischer Verstellung eines beweglichen Fahrzeugteils in einem Kraftfahrzeug weist einen elektromotorischen Antrieb und eine elektronische Steuereinheit auf. Von der elektronischen Steuereinheit wird sowohl der Antriebsstrom als auch die Bewegungsgeschwindigkeit des Antriebs erfasst. Die Steuereinheit unterdrückt bei einem über das normale Niveau hinaus auftretenden Anstieg der Bewegungsgeschwindigkeit die Erkennung eines Blockierfalles, wenn ein für diesen Anstieg der Bewegungsgeschwindigkeit erforderlicher Anstieg des Antriebsstroms nicht feststellbar ist.
Abstract:
A powered panel control apparatus and method using an electric motor with a rotatable armature. The control generates time periods for a predetermined amount of angular rotation of the motor armature during one complete rotation. An average time period is computed over a predetermined number of time periods and compared with a threshold time period to determine if an obstacle is present in the path of movement of the panel. Transient counts are accumulated for increasing average time periods over a number of time period samples to detect an obstacle. A threshold for normal noise variations is adjusted upon detection of a rough road condition to compensate for the effect of rough road conditions on the powered panel control apparatus.
Abstract:
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.
Abstract:
A powered panel control apparatus and method is used with an electric motor having a rotatable armature. The control detects and generates time periods between the rotation of the armature over a predetermined constant amount of angular rotation. An average time period is computed over a predetermined number of time periods and compared with a threshold time period to determine if an obstacle is present in the path of movement of the panel. Transient counts are accumulated for increasing average time periods over a number of time period samples to detect an obstacle. Endzone ramp compensation adjusts a threshold for the initial entry of the panel into a seal.
Abstract:
The device is intended to cut-off automatically the electric power supply of a motor (4), when the latter is rotatingly blocked by a mechanical resistance. This device comprises balls (5) which become rotatingly integral with the motor (4) and which are movable under the effect the centrifugal force generated during the rotation of the motor, the balls (5) cooperating with an electric contact (9) to switch on the electric power supply of the motor (4) when said centrifugal force reaches a certain threshold and to switch-off said power supply when the centrifugal force drops under the mechanical resistance opposed to the motor torque. Application particularly to automatic control devices for the opening and closing of garage doors.
Abstract:
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. 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 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. The door closer may be regenerative with respect to power and may be self-adjusting with respect to the latch boost/motor assist force applied and control of closing speed and opening speed. A
