Convertible top, sunroof and window lifter electronics

The invention relates to vehicles with an electric top and also electric sunroof or window lifters

Convertible vehicles are now usually offered with electronic roof technology. The driver can open and close it at the touch of a button. Window lifters or sunroofs that work in the same way are also well-known on the market. In summer, however, experience shows that drivers often leave the roof, window or sunroof open in the parking lot. The anti-theft alarm system remains active via the standby or secondary circuit. If it suddenly starts to rain, the interior remains unprotected, often without the driver noticing in time and being able to take appropriate action. The same can happen, for example, if a window is open while driving, and the driver is then inattentive for a few crucial seconds when closing it himself.

The object of the invention is to create an electric top or window or sunroof which does not have these disadvantages.

The solution according to the invention consists in connecting a commercially available rain sensor to the convertible top, sunroof or window electronics via the main and auxiliary circuits.

Such a rain sensor is an optical sensor that detects rain and then sends electronic impulses to the convertible top, sunroof or window lifter electronics, which then instructs the latter to close the sunroof when it rains. When the rain stops, the sensor detects this and can then instruct the window electronics to open the window again, for example.

It would therefore be particularly advantageous to connect such a microchip to the electronics, which stores the opening status, for example that of the window, and opens it again after the rain as wide as it was before the rain. This way, for example, a dog locked in the vehicle gets enough oxygen over a longer period of time or the interior can be ventilated without rain getting in.

The invention is shown in the schematic drawing in Fig. 1.

It shows a (pulse-generating) rain sensor 1 and a convertible top, sunroof or window lifter electronics 2. Both are connected to a main circuit 5. Furthermore

Both 1 and 2 are directly connected to one another via a standby or secondary circuit 4. In addition, a microchip 3 which stores the opening state of the window, for example, is connected to the lifting and locking electronics 2 or is integrated into it.

Claims (4)

1. Convertible top, sliding roof and window lift electronics ( 2 ), characterized in that the latter has a standby or secondary circuit ( 4 ), which is active when the vehicle is locked, is connected to a rain sensor ( 1 ) and that this electronically instructs the lifting and closing electronics ( 2 ) when it rains, for example to close the window if it is open, and that the sensor ( 1 ) and the electronics ( 2 ) are also connected to a main circuit ( 5 ). 2. Top, sliding roof and window lift electronics ( 2 ) according to claim 1, characterized in that a microchip ( 3 ) is additionally connected to or integrated into the lifting and closing electronics ( 2 ), and that this microchip ( 3 ) stores the opening state of, for example, the sliding roof before the rain and after the rain instructs the electronics ( 2 ) to open the sliding roof again as far as it was previously open. 3. Lifting and locking electronics ( 2 ) according to function and claims 1 and 2, characterized in that a rain sensor ( 1 ) is connected to lifting and locking electronics ( 2 ) with a connected or integrated microchip ( 3 ) that stores the opening state of a window, for example, via the main circuit ( 5 ), i.e. even when the engine is running, and thus closes an open rear window when it rains, for example, and then returns it to the previously set opening position. 4. Lifting and locking electronics ( 2 ) according to claim 3, characterized in that an acoustic or optical signal appears as soon as the rain sensor ( 1 ) detects rain and the microchip ( 3 ) simultaneously detects, for example, an open window.
