A motor control system comprises a motor control circuit, a non-transitory storage medium and a processing circuitry. The storage medium is configured to store a current threshold profile that is indicative of a current requirement of the motor control circuit for an operational cycle of a motor. The processing circuitry is configured to adjust the stored current threshold profile based on a change to the operational cycle of the motor (e.g., from standard to non-standard).

A retraction device includes an entrainment member to be releasably coupled to the movable furniture part, and a spring device for applying a force to the entrainment member in a direction opposite to an extension direction of the entrainment member. The spring device can be tensioned in the extension direction of the entrainment member by a spring holder separate from the entrainment member. A coupling device can couple a movement between the entrainment member and the spring holder, and can vary the distance of a fastening location of the spring device relative to the entrainment member upon extending the entrainment member towards the extension direction. The coupling device includes a control element having a longitudinal axis extending in the extension direction. To vary the distance between the fastening location and the entrainment member, the control element pivots about the longitudinal axis upon extending the entrainment member towards the extension direction.

A maintenance system for monitoring a gate device includes the gate device having a gate guide, a gate segment which is movably supported in the gate guide, and a sensor which monitors a gate guiding quality. A method for monitoring the gate device includes the gate device having a gate guide, a gate segment which is movably supported in the gate guide, a sensor which monitors a gate guiding quality arranged at the gate segment, and a maintenance unit. The method includes, when a movement of the gate segment occurs, detecting a vibration value and/or an acceleration value of the gate segment via the sensor, and transmitting the vibration value and/or the acceleration value as maintenance data to the maintenance unit.

A vehicle force measurement assembly includes a first rod, a second rod and an electronic controller. The first rod has a strain gauge mounted thereon. The first rod is dimensioned and configured to install to a first side of a vehicle door and a first side of a door opening of a vehicle body structure. The second rod is dimensioned and configured to install to a second side of the vehicle door and a second side of the door opening. The electronic controller is connected to the strain gauge and is wired and configured to detect forces applied to the first rod by the vehicle door in response to predetermined amounts of force being applied to the vehicle door.

An opening and closing control device includes a motor configured to drive, in an opening and closing direction, an opening and closing body that is supported a vehicle body and allowed to be opened and closed, a controller configured to control the motor, and a pulse encoder configured to output a pulse signal. The controller adjusts an advance angle of the motor, detects a rotational speed of the motor or an opening and closing speed of the opening and closing body according to pulse detection based on the pulse signal output from the pulse encoder, and detects a pinching state of the opening and closing body when the rotational speed of the motor or the opening and closing speed of the opening and closing body is equal to or less than a threshold value during advance angle control on the motor.

A motor vehicle drive assembly which is equipped with a drive element and an abutment, and also with at least one spring between the drive element and the abutment. In addition, there is at least one drive element sensor which, depending on the application of force by the drive element counter to the force of the spring and an associated relative movement between the drive element and the abutment, transmits sensor signals to a control unites. According to the invention, the drive element sensor, depending on the application of force by the drive element, generates different force-dependent, sliding sensor signals which are evaluated by the control unites, for example to drive an actuating element.

A front trunk system for an automotive vehicle a front trunk system for an automotive vehicle having a front trunk door and a frunk load floor includes a load sensor coupled to the frunk load floor that generates a load signal corresponding to a load on the load floor. The system further includes a controller coupled to the load sensor controlling an indicator when the load is greater than a load threshold.

A door open-close device for a vehicle configured to open or close a door opening portion by sliding and popping up a door disposed in a vehicle body includes a main arm motor fixedly disposed on a side of the vehicle body and configured to provide a driving power to operate the door, a main arm including a first end portion engaged to the main arm motor and a second end portion hingedly coupled to a side of the door and configured to transmit a rotation force to the door by receiving the driving power from the main arm motor, and a variable sub-arm including a first end portion hingedly coupled to the side of the vehicle body, a second end portion hingedly coupled to the side of the door, and when the door is opened or closed, disposed to change a length thereof due to engagement of a gear by driving a motor disposed in one portion.
