摘要:
The invention relates to a drive configuration for the motorized displacement of a displacement element of a motor vehicle, at least one drive having an electrical drive motor, in particular a DC motor, and a drive controller, which is associated with the drive and connected to a supply voltage UV, being provided, the drive not being designed as self-locking, so that in the case of a non-motorized displacement of the displacement element, the drive motor operates as a generator and generates a generator voltage UG. It is proposed that the drive controller is equipped with an overvoltage protector, which can be triggered by exceeding a limiting supply voltage UV, and that the configuration is further made so that the overvoltage protector can additionally be triggered by a non-motorized displacement of the displacement element if a limiting generator voltage UG is exceeded.

A door assembly includes a first door skin, a second door skin spaced apart from the first door skin and a door operator disposed between the first door skin and the second door skin. An arm extends from the door operator. The door operator includes a motor moving the arm to move the door between a closed position and an open position and between the open position and the closed position. A current sensor generates a current signal corresponding to the current to the motor. A position sensor in communication with the door arm generates a position signal corresponding to the position of the door relative to the frame. A controller communicates with the sensor and the motor. The controller controls a motor current to the motor in response to the current signal and the position signal.

A control system for a platform screen door system. The platform screen door system includes a door configured to be opened and closed. The control system includes a door drive means and a microprocessor door drive control means configured to control an opening and closing of the door according to a predetermined profile. Also included is at least one probe configured to monitor one or both of the door drive means and a motion of the door. Further included is a controller configured to control the door drive means such that when the controller is in use the controller brakes the door drive means when a signal from the probe is outside a predetermined door operating envelope.
摘要:
An access control apparatus for an access gate. The access gate typically has a rotator that is configured to rotate around a rotator axis at a first variable speed in a forward direction. The access control apparatus may include a transmission that typically has an input element that is operatively connected to the rotator. The input element is generally configured to rotate at an input speed that is proportional to the first variable speed. The transmission typically also has an output element that has an output speed that is higher than the input speed. The input element and the output element may rotate around a common transmission axis. A retardation mechanism may be employed. The retardation mechanism is typically configured to rotate around a retardation mechanism axis. Generally the retardation mechanism is operatively connected to the output element of the transmission and is configured to retard motion of the access gate in the forward direction when the first variable speed is above a control-limit speed. In many embodiments the transmission axis and the retardation mechanism axis are substantially co-axial. Some embodiments include a freewheel/catch mechanism that has an input connection that is operatively connected to the rotator. The input connection may be configured to engage an output connection when the rotator is rotated at the first variable speed in a forward direction and configured for substantially unrestricted rotation when the rotator is rotated in a reverse direction opposite the forward direction. The input element of the transmission is typically operatively connected to the output connection of the freewheel/catch mechanism.

A control apparatus for opening/closing a vehicle door includes a door opening/closing mechanism for operating the vehicle door, a driving source for driving the door opening/closing mechanism, a connecting/disconnecting apparatus interposed between the door opening/closing mechanism and the driving source, and a controlling apparatus for controlling the connecting/disconnecting apparatus. The controlling apparatus for opening/closing the vehicle door includes a door movement-detecting apparatus for detecting a movement of the vehicle door. The controlling apparatus switches the connecting/disconnecting apparatus from a connected state to a disconnected state when the driving source is stopped during in an opening/closing operation of the vehicle door. The controlling apparatus performs a repetition mode, in which the connecting/disconnecting apparatus repeats the connected state and the disconnected state, when the movement of the vehicle door is detected in the disconnected state of the connecting/disconnecting apparatus.

The invention relates to a method for controlled braking of an electrically powered lifting action in the event of a failure, such that at least one of the nominal values for “rotational direction” and/or “operating speed” and/or “door position” and/or “motor capacity” and/or “motor current” is ascertained and compared with an actual value, and such that a motorized braking process or motorized stopping process is triggered by a departure of the actual value from the nominal value that lies outside a predetermined range. In addition the invention relates to a device for applying said method.
摘要:
A sensor system for protecting a door of a vehicle from damage includes an electronic sensor operable to detect when an object external to the vehicle is within close proximity to the door of the vehicle. The sensor system provides a signal indicative of the proximity of the external object. The sensor system also includes a blocking hinge mechanism coupled with the signal. The hinge mechanism blocks the opening of the door beyond a distance wherein the vehicle door would strike the object.

A door apparatus includes a door having a hole and configured to be slidable with respect to a vehicle body, a member configured to open and close the hole, a first detector configured to detect a position of the member relative to the hole to determine an openness of the hole, a second detector configured to detect a position of the door relative to the body, and a unit configured to be activated to project from one to another of the body and the door, so as to abut on the another such that the door is stopped from sliding in an opening direction, when the openness is greater than a threshold, and the position is between a full-closed position and a midway position.
