A motor drive system configured to detect and prevent undesired movement of an item that is configured to be driven by the motor drive system. The motor drive system having: an electronic control unit operatively coupled to a rotor of the motor drive system, the electronic control unit being configured to detect undesired rotation of a shaft of the rotor, wherein the undesired rotation of the shaft is not caused by a force applied by the rotor; and wherein the electronic control unit of the motor drive system is configured to short windings of the motor drive system after a predetermined amount of undesired rotation of the shaft is detected by the electronic control unit such that further rotation of the rotor is prevented.

A method for the operation of a motorized flap arrangement of a motor vehicle, wherein the flap arrangement has a flap which is pivotable with respect to a motor vehicle body, wherein the flap arrangement has a back-driveable drive arrangement for the motorized adjustment of the flap and a control arrangement for controlling the drive arrangement. It is proposed that an, in particular gravitationally induced, predetermined flap deflection is detected by means of the control arrangement from a de-energized intermediate position of the flap in a monitoring routine and, in response to the detection of the predetermined flap deflection, a holding routine is triggered in which the drive arrangement is adjusted to a flap-holding position in a holding control circuit.

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 vehicle opening and closing body control device includes a drive control unit that opens and closes an opening and closing body of a vehicle using a motor as a drive source, wherein the opening and closing body performs the opening and closing operation based on an operation of a link mechanism formed by first and second link arms having a first rotation connection point with respect to a vehicle body and a second rotation connection point with respect to the opening and closing body, wherein an opening and closing body engagement portion is provided at a closed-side end of the opening and closing body, and an engagement failure detector that detects a failure in engagement of the opening and closing body engagement portion with the vehicle body engagement portion based on a change in a motor current value in the specific operation section at a time of full-closing control of the opening and closing body.

A safety device (200) is provided for a movable barrier system ((100). The safety device comprises a position sensor (210) mountable, in use, to or adjacent a barrier (110). A target (220) is mountable to the other of the barrier, such that movement of the barrier causes relative movement between the position sensor and the target. A controller (240) can communicate with the position sensor. The position sensor can detect movement of the target relative to the position sensor and output a signal to the controller. The controller can receive the output signal from the position sensor, determine one or more signal characteristics from the output signal, and compare the one or more determined signal characteristics with one or more predetermined signal characteristics to determine if the relative movement between the target and the position sensor is within a predefined range. A movement detection method is also provided.
