A diagnosis system diagnoses the integrity of an opening/closing device capable of opening and closing by driving a motor. A driving current acquisition unit acquires a driving current of the motor. A diagnosis unit defines a current waveform from a temporal change of the driving current acquired by the driving current acquisition unit and diagnoses the integrity of the opening/closing device based on the current waveform.

An exemplary method involves operating a door operator coupled to a door. The door operator includes a motor operable to move the door in at least one direction and a controller operable to control the motor. The method generally involves a calibration procedure including: with the door at a first position and the door having an initial speed, initiating, by the controller, measurement of a time duration; in response to the door reaching a target speed different from the initial speed, ceasing, by the controller, measurement of the time duration; and determining, by the controller, a maximum speed based on the time duration. The method further includes performing at least one operation based upon the maximum speed.

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.

An opening-closing member controller includes a control unit that executes an initialization process to store at least a fully closed position of an opening-closing member. In the initialization process, the control unit closes the opening-closing member, executes entrapment reversing control one or more times when entrapment is detected to open the opening-closing member, and closes the opening-closing member after the entrapment reversing control to store a position where the opening-closing member locks as the fully closed position.

A vehicle control device that includes a memory and a processor coupled to the memory, and that controls driving of a vehicle door. The processor being configured to determine multiple times whether or not a communication terminal communicable with the vehicle control device is in a cabin-external region, which is a predetermined region external to a cabin of the vehicle, in a case in which a door switch of the vehicle door has been operated. The processor being configured to perform control to drive the vehicle door in accordance with the operation of the door switch in a case in which it has been determined at least one time or more, based on determination results, that the communication terminal is in the cabin-external region.

A motor control system configured to detect a pinch condition of a structure actuated by a motor includes a pinch detection module configured to receive a current signal indicative of a motor current, determine a rate of change of current based on the current signal, and generate a pinch signal indicative of the pinch condition in response to either one of the motor current being greater than a current threshold and the rate of change of current being greater than a rate of change threshold. The motor control system further includes a position control module configured to control the motor to actuate the structure in response to an input and at least one of stop and reverse the motor in response to the pinch signal.

The disclosure relates to a revolving door assembly (1) comprising a central column (2) and at least one door panel connected to the central column (2) and rotatably arranged around a central axis (X) of the central column (2). The revolving door assembly (1) comprises a drive unit (6) enclosed within the central column (2), the drive unit (6) comprising a motor (13) for rotating the door panel (3). According to the revolving door assembly, the motor (13) has a central through hole (H1), wherein one or more cables (C1) of a cable configuration (C) are configured to pass through the central through hole (H1).

A method for positioning a movably arranged panel comprises the steps of determining a panel braking distance based on a physical property of the moveable panel and a physical property of at least one of a drive assembly and a drive motor. The panel braking distance corresponds to a distance covered by the moveable panel in a period of time starting from a decision to switch off the drive motor until stand-still of the moveable panel. The drive motor is switched off when an expected stop position is within a predetermined range around a desired stop position.

An automated window mechanism having a motor and a force measuring component. A movement path is defined for the window movement relative to a window frame. The force-measuring component measures the force required to move the window along the movement path. The force required is stored as a force map and is a function of position along the path. Deviations from the force map cause the motor to take measures which may include stopping the motor.

An automated window mechanism has a motor that moves a sliding window along a frame to open and close the window. A position sensor, such as an encoder, monitors a position of the sliding window relative to the frame. The automated window mechanism can receive an instruction to calibrate to the frame by disengaging the motor while the position sensor remains engaged. The user then manually moves the sliding window between two end points and then reengages the motor. The position sensor records the end points, and then the automated window mechanism uses the end points as limits of movement for the sliding window.
