An opening and closing body control apparatus includes a motor driving unit and a control unit. The motor driving unit outputs a predetermined application voltage to the motor, based on a control command from the control unit. The control unit is configured to: when an opening and closing body reaches a first position in front of a closing-up position, set a target speed of the motor to a closing-up time target speed at which a torque required for closing-up the opening and closing body is secured, and perform feedback control on the motor driving unit; and when the opening and closing body reaches a second position closer to the closing-up position than the first position, stop the feedback control, and control the motor driving unit so that the application voltage of the motor at the time is held.

A refrigerator is provided. The refrigerator includes a body including a door, a door opening device including a motor, and configured to open the door through a rotation of the motor, a first sensor configured to sense an opening of the door, a second sensor configured to sense a position of the door, and a processor is included, and the processor is configured to control, based on a user command for the opening of the door being obtained, the motor to rotate at a first speed, control, based on the opening of the door being sensed by the first sensor, the motor to rotate by reducing speed in stages to a second speed which is slower than the first speed, and control, based on a position of the door being sensed in a first position by the second sensor, the motor to open the door to a second position by rotating at the second speed.

A latch assembly for a closure panel of a motor vehicle and corresponding method of operation are provided. The latch assembly includes a latch housing for attachment to the closure panel and contains an actuation group to latch and unlatch the closure panel. An electronic control circuit that has a latch controller is disposed within the latch housing and is coupled to the at least one actuation group. The electronic control circuit includes a motor voltage and current sensing circuit for sensing a motor current and a motor voltage of a remote electric motor disposed remotely from the latch housing. The latch controller monitors and controls the actuation group and determine at least one of a motor rotational position and a motor speed of the remote electric motor based on at least one of the motor current signal and the motor voltage signal and controls the remote electric motor accordingly.

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.

A door drive device for adjusting and/or locking a vehicle door relative to a vehicle body including an adjustment member, a drive element operatively coupled to the adjustment member such that the adjustment member is movable with respect to the drive element for moving the vehicle door, a sensor device for measuring a measuring quantity indicative of a movement of the vehicle door to provide a sensor signal, a brake device operatively connected to the drive element for braking a movement of the vehicle door, and a control device for controlling operation of the door drive device. The control device is configured to compute, from the sensor signal obtained from the sensor device, an acceleration value indicative of an acceleration of the vehicle door and evaluate the acceleration value to distinguish movement of the vehicle door caused by a gravity force from movement caused by a user action.

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.

A method and an assembly for pivoting a movable component having a drive device with an electric drive motor in order to influence a pivoting of the component between a first setting and a second setting. A position sensor detects a position measure for a setting of the component and a speed parameter for a displacement speed of the component. During a displacement of the component with the speed parameter, an electrical setpoint current intensity for the electric drive motor is ascertained, and an associated setpoint voltage is set. The setpoint voltage is increased if a current intensity flowing through the drive motor is lower than the electrical setpoint current intensity, and the setpoint voltage is reduced if the current intensity flowing through the drive motor is higher than the electrical setpoint current intensity.

An apparatus includes a control unit. The control unit is configured to control an automatic flap and/or door. The flap and/or door is automatically transferrable from an open position into a closed position by at least one actuator. The flap and/or door is configured to press against a seal when in the closed position. In relation to a closing operation of the flap and/or door, the control unit is configured to determine time information in relation to an open state time duration during which the flap and/or door was in the open position before the closing operation. In relation to a closing operation of the flap and/or door, the control unit is also configured to operate the at least one actuator configured for the closing operation as a function of the time information.

The disclosed computer-implemented method may include receiving sensor data associated with a mobile device associated with a vehicle, wherein the sensor data includes at least one of an angular velocity vector, a linear acceleration vector, and a rotational acceleration vector recorded over a period of time, determining an event signature based on the sensor data, and detecting a door closing event associated with the vehicle based at least in part on the event signature. Other methods, systems, and computer-readable media are disclosed.

The proposed solution in particular relates to a method for adjusting an adjusting part (1) on a vehicle (F), wherein an adjustment of the adjusting part (1) is controlled by using an electronic detection device (2) which detects a potential obstacle in an adjustment path of the adjusting part (1) on the basis of at least one first measured value and generates at least one control signal (r(t)) for controlling the adjustment of the adjusting part (1). At least over a defined time period, a curve of the control signal (r(t)) and/or of the first measured value as well as a curve of at least one second measured value (a(t), i(t), v(t)) changing significantly on collision of the adjusting part (1) with an obstacle are stored so as to be read out and correlated with each other for a subsequent plausibility check.
