A door assembly includes a first door skin and a second door skin spaced apart from the first door skin. The assembly also includes an energy sensor generating an energy signature signal and a memory storing a door component operating signature. A controller is coupled to the accelerometer and forms a comparison of the energy signature signal to the door component operating signature and generates a door component operation status signal in response to the comparison.

A sliding door driving device includes: a power source; a motor that outputs power to open and close the door; a motor driving circuit that connects the power source and the motor to each other; and a motor control device that controls the motor driving circuit. The motor control device includes an inverter that converts DC power supplied from the power source into AC power, and a shunt resistor disposed between the power source and the inverter. The position detection unit of the motor control device obtains the rotation angle of the motor based on the output of the shunt resistor.

A method for detecting a pinching situation when moving an adjustable component for closing an opening by means of an electric motor in a vehicle comprises the following steps: providing a trigger threshold for a closing force exerted by the electric motor on the component or a physical variable on which it is based, with which the electric motor is operated, for at least one movement position of the component within a travel path available to it for the movement; moving the component into the movement position; determining a current value of the closing force or of the physical variable on which it is based for the at least one movement position; comparing the current value and the trigger threshold; and outputting a trigger signal which indicates the pinching situation dependent from the result of the comparison.

An open/close control device which detects pinching by an open/close body due to driving of a motor, includes a computing unit configured to compute an acceleration term based on a change in a rotational period of the motor, and a load applied to the motor based on the acceleration term, based on a signal indicating the rotation period of the motor, a determination unit configured to determine that the pinching by the open/close body occurred, when the load computed by the computing unit exceeds a predetermined determination value, and a determination value adjusting unit configured to increase the determination value when a local maximum value of the acceleration term exceeds a predetermined threshold value, or the acceleration term becomes less than or equal to a predetermined reference value, or the acceleration term decrease by a predetermined value or more, during a certain period after starting the motor.

A vehicle including a tailgate, a sensor system, and a processor is disclosed. The sensor system may be configured to capture inputs associated with the tailgate. The processor may be configured to obtain a trigger signal, and determine an object presence on the tailgate based on the inputs obtained from the sensor system responsive to obtaining the trigger signal. The processor may further prevent a tailgate movement responsive determining the object presence.

A method for preventing door jamming can include classifying an entire section into at least two or more sections by measuring a variation amount of current for opening and closing an electric door, setting a reference for determining whether an event occurs and for reversing an opening and closing operation of the electric door, determining whether the event occurs during the opening and closing operation of the electric door based on the reference, checking whether an integrated amount of a variation amount of current for driving the electric door, which is generated by the event, is greater than a threshold value based on it being determined that the event exists; and stopping the opening and closing operation of the electric door based on the integrated amount being greater than the threshold value, and a system for the same.
