Description

[0001] The invention relates to a display device for indicating the refueling of a motor vehicle with a CO2-neutral fuel.

[0002] Motor vehicles are typically powered by fuels derived from fossil fuels.

[0003] However, for motor vehicles with combustion engines, there is also the option of refueling with a CO2-neutral fuel, so that the vehicle can continue to be operated with these CO2-neutral fuels even after a ban on non-CO2-neutral fuel, or can be used, for example, in zones where only CO2-neutral operation of a motor vehicle is permitted.

[0004] However, the type of fuel used is not visible from the outside of the vehicle, making it difficult to recognize or verify CO2-neutral refueling.

[0005] The task is to create a display device that allows the external operator to determine whether a motor vehicle is fueled with CO2-neutral fuel or not. It is also the task to create a method for operating such a display device. Furthermore, it is also the task to create a motor vehicle with a means of indicating its fuel level.

[0006] The problem with the display device is solved by the features of claim 1.

[0007] One embodiment of the invention relates to a display device for indicating CO2-neutral refueling of a motor vehicle, comprising a display unit by means of which information about CO2-neutral refueling can be visually represented, and further comprising a control unit for receiving data and / or signals from the motor vehicle representing the refueling status with CO2-neutral fuel, such that upon receiving data and / or signals representing CO2-neutral refueling, the display unit is controlled in such a way that CO2-neutral refueling is indicated. By means of this display device, the refueling status with regard to refueling of the motor vehicle with CO2-neutral fuel can be indicated, so that it can be determined from the outside of the motor vehicle that CO2-neutral fuel is being used.

[0008] In one embodiment, it is advantageous if, upon receiving data and / or signals indicating that CO2-neutral refueling is not taking place, the display device is controlled in such a way that it either indicates that no CO2-neutral refueling has taken place or that no CO2-neutral refueling has taken place. In this case, no display can be made, or a negative indication regarding CO2-neutral refueling can be displayed.

[0009] In another embodiment, it is also advantageous to provide a communication device that communicates with the vehicle via data and / or signals to receive the data and / or signals relating to CO2-neutral refueling. The vehicle provides this data and / or these signals, and the display device receives this data and / or these signals and controls the display accordingly to show the refueling status.

[0010] It is also advantageous if the communication device is configured to transmit the refueling status via data and / or signals when CO2-neutral refueling is taking place. This allows other devices to receive this transmitted data and / or signals to display the refueling status themselves and / or to evaluate it in other ways, for example, to restrict or grant access to the vehicle based on its reported refueling status.

[0011] It is also advisable for the communication device to be configured to transmit data and / or signals indicating the refueling status when CO2-neutral refueling is not taking place, or to refrain from transmitting any data and / or signals when CO2-neutral refueling is not taking place. This allows the absence of CO2-neutral refueling to be communicated or indicated by a lack of communication.

[0012] It is also advantageous if the communication device communicates with the vehicle electronically and / or in encrypted form, for example via WLAN, Bluetooth and / or other communication methods. This allows for wireless communication or, alternatively, wired communication.

[0013] It is also advantageous if the connection between the communication device and the vehicle is preferably a one-time, secure connection. This allows the display device to be permanently connected, ensuring that the fuel level is always accurately displayed.

[0014] It is also advantageous if the display device can be permanently installed in a motor vehicle or retrofitted as an aftermarket part. This allows the display device to be factory-installed or retrofitted. This is particularly beneficial for used vehicles that are to be retrofitted.

[0015] The problem with the method is solved by the features of claim 9.

[0016] One embodiment of the invention relates to a method for operating a display device for indicating CO2-neutral refueling of a motor vehicle, comprising a display unit by means of which information about CO2-neutral refueling is optically displayed, and further comprising a control unit for receiving data and / or signals from the motor vehicle representing the refueling status with a CO2-neutral fuel, such that upon receipt of data and / or signals representing CO2-neutral refueling, the display unit is controlled in such a way that CO2-neutral refueling is indicated.

[0017] The problem relating to the motor vehicle is solved by the features of claim 10.

[0018] One embodiment of the invention relates to a motor vehicle with a display device according to the invention.

[0019] The invention will now be explained in detail using an exemplary embodiment and with reference to the drawings. The drawings show: Fig. 1 a schematic view of an embodiment of a display device in a display state which indicates the presence of CO2-neutral refueling, and Fig. 2 a schematic view of an embodiment of a display device in a display state which indicates the absence of CO2-neutral refueling.

[0020] The Fig. Figure 1 shows a display device 1 for indicating CO2-neutral refueling of a motor vehicle 5, with a display unit 2 by means of which information about CO2-neutral refueling can be visually displayed. The display unit 2 can be a type of screen or have a screen, a digital display, or even just a type of light that can illuminate, or similar. In this way, it can be visually indicated whether CO2-neutral refueling has taken place or not.

[0021] Furthermore, the display device 1 includes a control unit 3 for receiving data and / or signals from the motor vehicle 5, which represent the refueling status with a CO2-neutral fuel. Thus, upon receiving data and / or signals representing CO2-neutral refueling, the control unit 3 can control the display device 2 in such a way that CO2-neutral refueling is indicated.

[0022] Preferably, the display unit 2 also shows the official license plate number of motor vehicle 5, for example, S-PO 1234. For other motor vehicles 5, a different official license plate number can be displayed. This information serves to uniquely identify motor vehicle 5. Alternatively, a unique identification number or letter / number combination could also be displayed if this is required for evidentiary purposes.

[0023] Alternatively, if data and / or signals are received indicating that CO2-neutral refueling is not taking place, the display unit 2 can be controlled in such a way that no CO2-neutral refueling is displayed or that the absence of CO2-neutral refueling is indicated; see also Fig. 2.

[0024] Furthermore, the display device 1 includes a communication device 4 which communicates with the motor vehicle 5 via data and / or signals in order to receive data and / or signals relating to CO2-neutral refueling. The motor vehicle 5 generates data and / or signals from its other systems that represent the refueling status of the motor vehicle 5, and the communication device 4 receives this data and / or these signals and forwards them to the control unit 3.

[0025] According to one embodiment, the communication device 4 is also configured to transmit the refueling status in the case of CO2-neutral refueling by means of transmitted data and / or signals. In this way, other devices or equipment can recognize the refueling status of the motor vehicle 5 by receiving this data and / or signals and initiate appropriate control actions, etc.

[0026] The communication device 4 can also be configured to transmit data and / or signals indicating the refueling status when CO2-neutral refueling is not taking place, or to refrain from transmitting any data and / or signals when CO2-neutral refueling is not taking place. Other devices or equipment can then detect the refueling status of the vehicle 5 by receiving or not receiving this data and / or these signals, and initiate appropriate actions, etc.

[0027] In one embodiment, the communication device 4 communicates with the motor vehicle 5 electronically and / or in encrypted form, for example via WLAN, Bluetooth and / or other communication methods.

[0028] For this purpose, the display device 1 can be connected to the motor vehicle 5 via a coupling using the communication device 4, wherein the coupling of the communication device 4 to the motor vehicle 5 preferably takes place only once and is secured. This way, a new coupling does not have to be made every time.

[0029] One aspect of the inventors' concept is that the display device 1 can be permanently installed in a motor vehicle 5, for example, on a windshield of the motor vehicle 5, or retrofitted to a motor vehicle 5. This allows a new vehicle to be equipped with it or a used vehicle to be retrofitted. Preferably, the display device 1 is housed in a relatively small casing and can thus be positioned, for example, on a windshield of the motor vehicle 5, so that the display device 2 can be easily observed from the outside.

[0030] The invention also relates to a method for operating a display device 1 for indicating CO2-neutral refueling of a motor vehicle 5, with a display unit 2 by means of which information about CO2-neutral refueling is optically displayed, furthermore with a control unit 3 for receiving data and / or signals from the motor vehicle 5, which represent the refueling status with a CO2-neutral fuel, such that upon receipt of data and / or signals which represent CO2-neutral refueling, the display unit 2 is controlled in such a way that CO2-neutral refueling is indicated.

[0031] The display device 1 is preferably arranged in the motor vehicle 5, and the procedure is then also carried out in the motor vehicle 5. Reference symbol list 1 Display device 2 Display unit 3 Control unit 4 Communication device 5 Motor vehicle
