Abstract

The present invention discloses an operating liquid container system comprising at least one operating fluid container, a quality and/or filling level sensor arranged in the operating liquid container, for determining at least one quality characteristic of the operating liquid contained in the operating liquid container and/or a filling level of the operating liquid container, and a display device arranged in a tank recess and/or tank flap of the operating fluid container system, wherein the display device is connected to the quality and/or filling level sensor by means of a data line for transmitting data from the quality and/or filling level sensor to the display device, wherein the data represents at least one quality characteristic of the operating liquid contained in the operating liquid container and/or the filling level of the operating liquid container.

Claims

1. An operating liquid container system comprising

at least one operating liquid container;

a quality and fill level sensor arranged in the operating liquid container for determining at least one quality property of the operating liquid contained in the operating liquid container and a fill level of the operating liquid container; and

a display device arranged in a tank recess and/or tank flap of the operating liquid container system;

wherein

the display device is connected to the quality and fill level sensor by means of a data line for transmitting data from the quality and fill level sensor to the display device, wherein the data represent at least one quality property of the operating liquid contained in the operating liquid container and the fill level of the operating liquid container; and

the display device (75) is designed to display the data representing the at least one quality property and the fill level.

2. The operating liquid container system as claimed in claim 1, wherein

the operating liquid container system comprises a fill control device, wherein the fill control device is connected to the quality and fill level sensor for receiving the data representing the at least one quality property and the fill level by means of the data line;

and

the fill control device is connected to the display device by means of the data line for transmission of the data representing the at least one quality property and the fill level.

3. The operating liquid container system as claimed in claim 2, wherein

the fill control device is configured to receive, in addition to the data transmitted by the quality and fill level sensor, also data representing a tilt of the operating liquid container;

and

the fill control device is configured to determine an actual fill level by means of the data transmitted from the quality and fill level sensor and the data representing the tilt of the operating liquid container.

4. The operating liquid container system as claimed in claim 3, wherein

the operating liquid container comprises a tilt sensor, by means of which the tilt of the operating liquid container can be determined, wherein the tilt sensor is connected to the fill control device via a second data exchange connection, via which the data determined by the tilt sensor and representing the tilt of the operating liquid container can be transmitted to the fill control device.

5. The operating liquid container system as claimed in claim 2, wherein the fill control device is configured to output a warning signal via a data output unit when a quality property of the operating liquid present in the operating liquid container is determined which lies below and/or above a predefined threshold limit.

6. The operating liquid container system as claimed in claim 5, wherein the fill control device is configured to transmit the warning signal via the data line to the display device, whereupon the display device outputs the warning signal.

7. The operating liquid container system as claimed in claim 5, wherein

the operating liquid container comprises at least one actuator which can be actuated electrically and/or electromagnetically, and by means of which the termination of a filling process of the operating liquid container can be initiated;

the fill control device is connected to the actuator via a data exchange connection;

the fill control device is configured to transmit a stop filling signal to the actuator via the data exchange connection when the warning signal is output; and

on receipt of the stop filling signal, the actuator initiates the termination of the filling process.

8. The operating liquid container system as claimed in claim 7, wherein

the at least one actuator is configured as an operating and/or filling purge valve arranged in the motor vehicle tank, wherein the operating and/or filling purge valve can be actuated electrically and/or electromagnetically between an open position and a closed position;

the motor vehicle tank is fluidically connected to a purge line by means of the operating and/or filling purge valve in the open position; and

the motor vehicle tank is fluidically separated from the purge line by means of the operating and/or filling purge valve in the closed position.

9. The operating liquid container system as claimed in claim 7, wherein

the at least one actuator is configured as a check valve arranged in a filler pipe opening into the motor vehicle tank;

the check valve can be actuated electrically and/or electromagnetically between an open position and a closed position;

the motor vehicle tank is fluidically connected to the filler pipe, by means of the check valve in the open position;

the motor vehicle tank is fluidically separated from the filler pipe by means of the check valve in the closed position, or the internal width of the filler pipe is reduced by means of the check valve in the closed position.

10. The operating liquid container system as claimed in claim 7, wherein,

the at least one actuator is configured as an interference body arranged in a filler pipe opening into the motor vehicle tank, wherein the interference body can be actuated electrically and/or electromagnetically between an open position and an interference position;

the interference body in the open position does not reduce an internal width of the filler pipe; and

the interference body in the interference position protrudes into the filler pipe and reduces the internal width of the filler pipe.

11. The operating liquid container system as claimed in claim 7, wherein

the motor vehicle tank is fluidically connected to the activated carbon filter by means of the shut-off valve in the open position; and

the motor vehicle tank is fluidically separated from the activated carbon filter by means of the shut-off valve in the closed position.

12. The operating liquid container system as claimed in claim 7, wherein

the at least one actuator is configured as an electromagnet arranged in a filler neck of a filler pipe opening into the motor vehicle tank, wherein the electromagnet can be actuated between an active state and a passive state;
