SPEED CONTROL UPDATE RATE SLOWDOWN
An open roof construction for use in a vehicle roof of a vehicle comprises a moveably arranged closure member (2) for selectively covering or at least partially exposing an opening (3) in the vehicle roof, an electric motor (4) operatively coupled to the closure member through a mechanical drive assembly (5) for moving the closure member, an electric driving unit (6) for providing a supply signal to the electric motor and a pinch control module (7) operatively coupled to the electric driving unit for controlling operation of the electric motor in a pinch event. The pinch control module comprises at least a PWM controller (8) capable of supplying a duty-cycle. The pinch control module is configured to calculate a pinch force signal based on an input of measured data, incur a safety stop of the closure member (2) in a pinch event during a closing operation of the closure member when the calculated pinch force signal exceeds a first pinch threshold (11) and by an immediate reversal of a polarity of the supply signal by the electric driving unit (6) to the electric motor (4). The pinch control module is configured having a second threshold (12) which is set to a lower level than the first threshold, which second threshold marks the start of a suspected pinch event.
