摘要： A drive circuit for driving an electro-optical device like an optically switchable glazing, e.g. a glass panel provided with a PDLC or SPD layer, comprises a set of input terminals for receiving an alternating input voltage at a first frequency; a set of output terminals for supplying an alternating output voltage at a second frequency; a control circuit generating a control signal dependent on an input signal, the input signal representing a charge state of the electro-optical device; and a current-direction circuit for controlling a current-flow direction of an electrical current in response to the control signal. The control circuit and the current-direction circuit are thereby configured to control the second frequency such that the electro-optical device is prevented from degradation, while keeping an energy consumption low.

摘要： A method for testing an open roof assembly comprises steps of providing a test device, the test device comprising a generic control unit, a force sensitive sensor and a drive circuitry; operatively coupling the motor drive assembly to the drive circuitry; positioning the force sensitive sensor in the roof opening; and operating the generic control unit to move the closure member from the open position to the closed position such that the closure member collides with the force sensitive sensor, to receive force data from the force sensitive sensor and to determine from the force data a system property constant. The system property constant is representative for a maximum pinch force of the open roof assembly.

摘要： In a drive circuitry for outputting a drive voltage to an optically switchable panel, the drive voltage is an alternating (AC) drive voltage. In an operating state of the drive circuitry, the drive voltage is supplied to the optically switchable panel. In said operating state, the drive circuitry is configured to vary the drive frequency of the alternating drive voltage without affecting an optical state of the optically switchable panel.

摘要： A transparent panel (20) for use in a vehicle roof of a vehicle comprises a layered stack comprising a first (23) and a second (24) transparent pane and an electrically conductive assembly arranged between the second and the third main surface, wherein a through hole (22) is provided in the second pane (24). The panel further comprises an electric apparatus (30) mounted on a passenger compartment side covering the through hole (22). The electric apparatus is electrically coupled to the electrically conductive assembly through the through hole.
The electrically conductive assembly electrically couples a first (41) and a second (42) terminal and is arranged between and adjacent to the first and the second terminals (41, 42), wherein an optical transmissivity of the transparent panel is not visually deteriorated in an area of the electrically conductive assembly around the electric apparatus (30).-

摘要： 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.

摘要： An open roof assembly is configured for providing a closable roof opening in a vehicle roof. Thereto, the open roof assembly comprises a closure member that is moveably arranged for opening and closing the roof opening and a detection system for detecting an object in the roof opening. The detection system is configured to provide an entrapment signal if a foreign object is detected in the roof opening, when the closure member is moving and a collision may occur. The detection system is further configured to provide an operating signal, when an object is detected performing a predefined action. Based on the operating signal a control unit may execute an associated function.

摘要： A movably arranged vehicle component is operatively coupled to and may be driven by an electric motor. The electric motor is supplied with a motor current to drive the movement of the vehicle component. A method for detecting a movement obstruction comprises the steps of supplying the electric motor with a supply voltage, thereby supplying the motor current; determining a frequency content of the motor current; and analysing the frequency content to determine whether the movement obstruction is present or not.
A motor control system is configured to perform the above-mentioned method.-
