Systems, methods, and apparatus for detecting movable barrier disengagement are provided. A movable barrier operator system includes a motor configured to be coupled to a movable barrier and move the movable barrier, a motor sensor configured to measure a load value of the motor, communication circuitry configured to receive, from a remote control, a state change request to cause movement of the movable barrier, and a processor circuit. The processor circuit is configured to cause actuation of the motor in response to receipt of the state change request, detect, based on the load value, a disengagement between the motor and the movable barrier, and cause a communication to be sent, in response to detecting the disengagement, to a remote server, the communication indicative of motor disengagement.

An open roof assembly for use in a vehicle roof comprises a moveably arranged closure member and a drive system operatively coupled to the closure member for moving the closure member along a motion trajectory. The drive system comprises an electric motor and a control unit for controlling operation of the electric motor. The control unit comprises a mathematical model describing at least a part of the drive system; model parameters and a motion reference field. The control unit is configured to update the model parameters based on a received value of a first drive system variable; determine a value of a second drive system variable using the mathematical model; determine a comparison value by comparing the value of the second drive system value and a corresponding reference value of the motion reference field; and detect presence of an obstruction if the comparison value lies outside a predetermined value range.

A trunk door opening/closing assistance apparatus including: a torque detection part which detects a torque input by a user to open/close the trunk door of a vehicle; a control unit which provides assist torque support in addition to the torque applied by the user within a total torque range required to open/close the door when the user manually opens or closes the trunk door; and a motor drive part which drives a motor for assisting the opening or closing of the trunk door with a direction and a strength which are controlled by the control unit.

A vehicle includes a body and a door that is movably mounted to the body. The door has a powered latch and an electrically-powered actuator that extends and retracts a plunger from an inner side of the door. A controller unlatches the powered latch and actuates the electrically-powered actuator such that the plunger contacts the body and pushes the door open. The controller then controls the electrically-powered actuator to retract the plunger while the door is open.

A vehicular opening/closing body control device includes: a braking control unit configured to apply a braking force to an opening/closing body provided in an opening in a vehicle; a traveling state determination unit configured to determine a traveling state of the vehicle; an abnormality detection unit configured to detect occurrence of a full-closing abnormality in which the opening/closing body is not held in a fully-closed state during the traveling of the vehicle; and a record holding unit configured to hold a detection record of the full-closing abnormality, wherein the braking control unit executes braking control through detection of the full-closing abnormality of the opening/closing body, and in a case where the detection record of the full-closing abnormality is held after the vehicle stops, executes the braking control of the opening/closing body based on the detection record of the full-closing abnormality before the vehicle travels.

It is provided an assembly for adjusting an adjustment element relative to a stationary section of a vehicle, in particular a vehicle door relative to a vehicle body, which comprises a drive motor for electromotively adjusting the adjustment element, an electrically actuatable coupling device, a sensor device for measuring an acceleration value of the adjustment element during an adjustment of the adjustment element, and a control device for controlling the drive motor and the coupling device. The control device is configured to calculate a force value or torque value acting on the coupling device with reference to an acceleration value obtained via the sensor device during an adjustment of the adjustment element in a slip state of the coupling device.

A door closer may utilize a door closing device (e.g., spring) and a force adjustment device (e.g., a motor) in order to allow for manual door opening and assisted door closing. During operation, as a door is manually opened, the spring is loaded (e.g., compressed or tensioned) above its pre-loaded closed position state. Once manual opening is completed, the spring that is loaded during opening begins returning to the pre-loaded closed position state, and thus, moves the door automatically towards the closed position. Depending on the pre-loaded spring setting, the closing force of the door may not be enough to close the door, or to close the door with the preferred force. As such, during closing a controller may engage a motor not to drive the door directly, but to increase the pre-load of spring to increase the closing force in order to allow the door to close as preferred.

A system for detecting broken springs in overhead doors having automatic door openers includes an automatic door opener having a motor, a sensor configured to monitor performance of the motor in the door opener, and a processor in communication with the sensor. The processor is configured to compare the motor performance with a predetermined threshold level and send an alert when motor performance exceeds the predetermined threshold level.

A method and a device for closing a door on a door opening of a vehicle are provided. The closing device includes a seal formed between the door and the door opening for separating an interior space and an exterior space from each other when the door is in a closed position. The device also includes a door drive for moving the door and a controller coupled to the door drive for controlling movement of the door based on an operating request of a user. The controller includes a condition monitoring unit configured to determine and use at least one variable state variable chosen from the group consisting of the device, the door, the door opening, and the installation environment of the door. The controller is configured to generate a value of at least one closing parameter for closing the door depending on the at least one variable state variable.

An automatic door device includes a driving motor and a transmission system. An input end of the transmission system is coupled to an output shaft of the driving motor, an output end of the transmission system is coupled to a door shaft, and the transmission system has a transmission link to transmit an output torque of the driving motor to the door shaft. A clutch mechanism is disposed on the transmission link of the transmission system. Accordingly, when the door is subjected to an external force, the transmission link between the door and the driving motor can be automatically disconnected, so that while an automatic door function implemented, it is ensured that a user may not be affected by the resistance brought by the automatic door device when the user opens/closes the door manually, thereby optimizing user experience.
