  • Patent number: 8615346
    Abstract: The invention relates to a method for controlling a blocking member (11) of a functional component (30), particularly of a steering column (30) of a motor vehicle, particularly of a motorcycle, having a drive (20) by which the blocking member (11) can be moved into a locking position (1) and into an unlocking position (2) and vice versa, wherein the blocking member (11) engages mechanically with the functional component (30) when in the locking position (1), releases from the functional component (30) when in the unlocking position (2), and the locking process is started via a defined triggering action on the part of the operator, the blocking member (11) being moved from the unlocking position (2) into the locking position (1) during said locking process.

  • Publication number: 20090051294
    Abstract: A door entry or interior Welcome lighting system for a motor vehicle includes a lamp and a control circuit. The lamp has at least one RGB-LED component with an LED shining red, an LED shining green, an LED shining blue and connecting lines for separately controlling the three LEDs. The control circuit is coupled to the connecting lines and receives control signals on control lines which indicate on the one hand the requirement for switching on the illumination and, on the other hand, at least one operational condition of a closure device of the motor vehicle. On receipt of the control signals indicating the requirement for switching-on the illumination, the control circuit controls the three LEDs, in a first control mode so that a continuous, white to yellow-white illumination of the door entry area or the motor vehicle interior is produced.
