Abstract

A system is provided in order to automatically close a filler inlet compartment lid of a car when the lid is in an unintended open position. When predefined signals which are considered to indicate the termination of a refueling operation occur, the system activates a filler inlet compartment lid closing mechanism so that the filler inlet compartment lid is automatically closed and locked. This can take place when the filler inlet compartment lid is completely open or when the lid is in an only slightly lifted intermediate position. The filler inlet compartment lid may reach such a slightly lifted intermediate position, for example, in a drive-through car wash when triggered by the pressure of the car wash brushes.

Claims

1. An operating system for a filler inlet compartment lid of a motor vehicle, comprising a control unit which responds to signals indicating predefined conditions and designed for controlling the operating system for closing the filler inlet compartment lid, and a sliding-block part which is arranged inside a vehicle body, which can be rotated or displaced by a driving element, and which has a guide slot, open on one side and defining two levels, and a locking pin mounted on the filler inlet compartment lid which can enter the guide slot, the locking pin, according to the position of the sliding-block part, locking the filler inlet compartment lid in a closed position or moving the filler inlet compartment lid into a slightly lifted intermediate position.

2. The operating system according to claim 1, and further comprising a pressure sensor, which responds to a pressure on the filler inlet compartment lid when the lid is closed, for controlling the driving element for the sliding-block part in order to bring the sliding-block part into a position in which the filler inlet compartment lid takes up the intermediate position.

3. The operating system according to claim 1, and further comprising a pressure sensor which can be operated in the intermediate position of the filler inlet compartment lid for generating a filler inlet compartment lid closing signal for the driving element.

4. The operating system according to claim 1, wherein when one of the signals indicating predefined conditions occurs, the driving element moves the sliding-block part into a locking position.

5. The operating system according to claim 1, and further comprising a closing drive which changes the filler inlet compartment lid from its completely opened position into the intermediate position.

6. The operating system according to claim 1, wherein the sliding-block part with its driving element, the control unit, and sensors are combined to form a module which can be mounted as one unit.

7. The operating system according to claim 5, wherein the sliding-block part with its driving element, the control unit, and sensors are combined to form a module which can be mounted as one unit.

8. The operating system according to claim 7, wherein the closing drive is also combined with the driving element, the control unit, and the sensors to form the one unit.
