A method for driving an electromechanical sliding door in a transportation vehicle, wherein the sliding door has an adjusting mechanism with a rolling carriage guided in a guide rail and a first electric drive motor. A fixing mechanism with a second electric drive motor and also a locking mechanism is also provided, which locking mechanism allows the rolling carriage to be arrested in any desired position. Here, the locking mechanism is driven by the second electric drive motor. The method may include driving the second electric drive motor with an input voltage which lies below a threshold voltage for tripping the locking mechanism, continuously increasing the input voltage for the second electric drive motor, and locking the locking mechanism when the input voltage for the second electric drive motor exceeds the threshold voltage for tripping the locking mechanism.

A lock release control device for an opening and closing body configured to control an opening and closing body that opens and closes an opening portion of a vehicle. The opening and closing body comes into contact with a sealing member provided on a vehicle body side of the vehicle in a fully closed state. The vehicle includes a locking device and an opening and closing actuator. The locking device restrains the opening and closing body in a fully closed position. The opening and closing actuator displaces the opening and closing body by rotation of a motor to change the opening and closing body from one of two states including an open state and a closed state to another of the states. The lock release control device is configured to execute an open command acquisition process, a pull-in process, and a lock release process.

A method for operating a boarding system for a vehicle includes reading in an inclination signal. The inclination signal represents an inclination of the boarding system relative to a reference. The method also includes reading in at least one movement process of at least one boarding element of the boarding system representing process signals and includes determining an operating signal for operating the boarding system using the inclination signal and the at least one process signal.

An opening-closing body control device for a vehicle includes: an opening-closing control unit configured to control an operation of an opening-closing body provided in an opening portion of a vehicle by controlling energization of a motor serving as a drive source. When the opening-closing body being moved based on a driving force of the motor is to be stopped, the opening-closing control unit sets a free running period during which free rotation of the motor is allowed, and executes brake control for generating a braking force in the motor after the free running period elapses.

An open roof assembly for use in a vehicle roof of a vehicle comprises a moveably arranged closure member for selectively covering or at least partially exposing an opening in the vehicle roof, an electric motor operatively coupled to the closure member through a mechanical drive assembly for moving the closure member, an electric driving unit for providing a supply signal to the electric motor and a control unit operatively coupled to the electric driving unit for controlling operation of the electric motor. The electric driving unit comprises four switching devices in a bridged configuration and the control unit is configured to control a motion of the closure member by controlling operation of the switching devices, and to incur a safety stop during a motion of the closure member by an immediate reversal of a polarity of the supply signal.
