  • Patent number: 6036254
    Abstract: A control device for a vehicle having two roofs; a first roof which is permanently attached to the vehicle, and a second roof which can be removed from the vehicle. In order for the control device to no longer operate the first roof when the second roof is mounted and connected to a locking mechanism which serves as a releasable connection of both roofs with a windshield frame of a vehicle, a transmitter is arranged such that it sends a signal if the locking mechanism is in the proper locked position. A second transmitter is provided which sends a signal when the first roof is open. As a result, the control device suppresses the operation of the first roof if signals from both transmitters are received simultaneously.
