A method of controlling a movable closure member of a vehicle is provided. The method includes the steps of: determining an initial position of the movable closure member; initiating movement of the movable closure member; and switching power between a first shunt and a second shunt when the movable closure member is at an intermediate position between the initial position and a final position of the movable closure member. The shunt may be traces on a printed circuit board. Within the method, the initiating step may include switching power to the first shunt when the initial position of the movable closure member is determined to be a closed position, and switching power from the first shunt to the second shunt when the movable closure member is at an intermediate position. The movable closure member may be a side door window, a rear gate window, a power sliding door, a sunroof, or a moon roof.

The disclosure further relates to a swing door and a room with a swing door.

A machine tool includes: a cover; a door; a drive mechanism; a detection unit; and an operation panel that receives an operation for the machine tool. A control device of the machine tool performs: processing to control the drive mechanism such that the door is opened, based on the operation panel receiving a first opening operation; processing to obtain an actual position from the detection unit and store the actual position as an opening position of the door, based on the operation panel receiving an operation to determine a position; and processing to control the drive mechanism such that the door is located at the opening position, based on the operation panel receiving a second opening operation. An opening speed of the door during the first opening operation is slower than an opening speed of the door during the second opening operation.

The present invention provides an anti-pinch detection method and system comprising: determining a first current change rate according to a current collected in a present period and a previous period; determining a second current change rate according to the current collected in the present period and a target period, there being N periods between the target period and present period; detecting whether a closure component encounters an obstacle according to the second current change rate. If yes, determining the stiffness of the obstacle according to the first current change rate; determining a real-time obstacle compression distance according to a contact position zero point and a motor position collected in real time; and determining a real-time anti-pinch force according to the stiffness of the obstacle and the real-time obstacle compression distance, and controlling a motor to reverse when the real-time anti-pinch force is greater than a preset anti-pinch detection threshold.

A mechanism for opening and closing an overhead door includes a drive loop coupled to the overhead door, a motor with a drive shaft and a drive wheel for driving the drive loop. A one-way bearing couples the drive shaft to the drive wheel, which one-way bearing is configured to transmit torque from the motor to the drive wheel, as the motor rotates the drive shaft in a first rotational direction to raise the overhead door, and configured so that torque is not transmitted to the drive wheel as the motor rotates the drive shaft in a second rotational direction opposite the first rotational direction. As a result, the motor applies torque through the one-way bearing to raise the overhead door and to support the weight of the overhead door while lowering the overhead door.

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 truck is provided that includes a bed section located rear of a cab section. The bed section is bounded on each side by opposing first and second upward-extending sidewalls, respectively. The truck also includes a truck bed cover that sits over the bed section on at least the first and second upward-extending sidewalls, and includes a door portion to create selective accessibility to the bed section of the pickup truck. The door portion is movable with respect to the first and second upward-extending sidewalls between open and closed positons via an automatic bed cover drive assembly that moves the door portion between open and closed positons according to a plurality of velocities within a predetermined variance.

The invention concerns a method for controlling a drive (5) for a leaf (1), in particular for a door leaf or a window leaf, including the following steps: Measuring a measured value (vr) of a kinetic quantity of the leaf (1), comparing the measured value (vr) with a tolerance range (TB) of a reference travel curve (SFK), driving the leaf (1) by the drive (5) according to the reference travel curve (SFK). Upon the measured value (vr) leaving the tolerance range (TB), the leaf (1) is set to a freewheel (FL) in which the drive (5) is suspended.

An opening and closing body controller for controlling an opening and closing body that opens and closes an opening of a vehicle body includes driving means that drives the opening and closing body to open and close, user detection means that detects whether a predetermined motion is performed by a user when a distance between the user and the opening and closing body is within a predetermined range, and control means. The control means is configured to, when the user detection means detects the predetermined motion of the user, control the driving means so that the opening and closing body opens and closes at a first speed if the distance between the user and the opening and closing body is within the predetermined range, and so that the opening and closing body opens and closes at a second speed if the distance is out of the predetermined range.

A passenger safe exit assist device and a method thereof obtain information of an obstacle around a vehicle and a speed at which the door of the vehicle is opened, set a virtual first line along the obstacle, and control the speed at which the door is opened, based on at least one of the first line or the speed. The device and method provide a customer with various safe exit modes such that the customer freely selects a mode and experiences alighting safely from the vehicle.
