A method for state-based maintenance of an access device of a vehicle, in particular of a public transport vehicle, wherein the access device includes a moveable element and an electric drive for moving the moveable element and is attached to the vehicle. The drive is controlled with control signals, wherein actual state signals for describing the state are generated based on a detected state of the access device. The control signals are applied to a physical simulation model for computationally simulating the access device and determining expected target state signals and wherein based on a comparison between the actual state signals and associated target state signals, a maintenance state of the access device is determined. The simulation model is adjusted based on the comparison between the actual state signals and the associated target state signals.

A method for detecting objects in the surroundings of a vehicle for a door opening system or a collision warning system for vehicle doors using at least one surroundings sensor is disclosed. The vehicle includes at least one movable component. The method includes detecting objects in the surroundings of the vehicle using the at least one surroundings sensor, detecting a current position of the at least one movable component, and identifying false objects from the detected objects based on their positions between the at least one movable component in its current position and in its normal position.

A vehicle roof assembly comprises an electronic control circuitry and at least one sensor operatively coupled to the electronic control circuitry. An output of the sensor exhibits hysteresis. A method of operating the vehicle roof assembly comprises performing a sensor power-down sequence. The sensor power-down sequence of steps comprises switching off the sensor; switching on the sensor; detecting the output of the sensor; storing the output of the sensor in a memory; and switching off the sensor. The method prevents inadvertent position drift due to hysteresis effects during a power toggle.

A monitoring apparatus includes a sensing circuitry configured to sense a locked or released state of a door of a railway vehicle, or sense an open or closed state of the door, and a processor. The processor acquires an output of the sensing circuitry, and position information in an opening or closing direction of the door, and determines an abnormality in a configuration related to an opening or closing operation of the door, based on a match between the acquired output of the sensing circuitry and the position information.

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 refrigerator is configured to enable a user to open doors of the refrigerator easily. The refrigerator performs a method for controlling the doors to prevent from opening due to a malfunction.

A door sensor may include one or more emitters configured to emit an emission beam comprising IR light during an emitting phase. The door sensor may further include one or more receptors configured to receive a reception beam comprising the IR light reflected off of a surface during a listening phase and an interference beam from an adjacent door sensor. The door sensor may further include a controller operatively coupled to a memory storing computer-readable instructions that, when executed by the controller, cause the controller to: determine one or more of the frequency and phase of the interference beam; determine whether the door sensor should be primary or secondary to the adjacent door sensor; and adjust a timing of one or more of the emitting phase and the listening phase to reduce interference from the adjacent door sensor.

Disclosed are a method and a device for controlling opening and closing of a vehicle door, a vehicle, and a computer readable storage medium. On the basis of a vehicle provided with a capacitive sensing area having a plurality of capacitive sensing points, a touch sliding operation executed by a vehicle user is acquired via the capacitive sensing area; according to trigger state information of the touch sliding operation for the plurality of capacitive sensing points, it is determined whether the touch sliding operation is an accidental touch operation; and finally, in response to that the touch sliding operation is not the accidental touch operation, according to a triggering sequence of the touch sliding operation for the plurality of capacitive sensing points, the vehicle door is immediately controlled to be opened or closed.

An infrared (IR) sensor for use in a door sensor. The IR sensor may include a plurality of emitters arranged in multiple rows. Each emitter of the plurality of emitters may be configured to emit an emission beam comprising IR light. A plurality of receptors may be arranged in multiple rows. Each receptor of the plurality of receptors may be configured to receive a reception beam comprising the IR light reflected off of a surface. One or more lenses comprising refractive elements may be configured to duplicate and direct one or more of the emission beams and one or more of the reception beams onto the surface to form an IR pattern. The IR pattern may include multiple IR curtains. One or more of the receptors and/or emitters may be deactivated to change a width of the IR pattern and/or number of IR curtains.
