Abstract

A refueling system for motor vehicles, that includes a motor vehicle with a first communication interface and with a control unit, as well as a refueling installation, a second communication interface, which has a communication connection to the first communication interface for the transmission of data, as well as a tank with a fuel. The refueling installation has a sensor device, which is equipped to determine a fuel material property of the fuel of the refueling installation and to transmit it to the motor vehicle, so that the control unit of the motor vehicle controls a vehicle component on the basis of the determined fuel material property.

First claim

What is claimed is:

1. A refueling system for a motor vehicle, the refueling system comprising:
a motor vehicle comprising:
a first communication interface; and
a control unit;

a refueling installation comprising:
a second communication interface, which has a communication connection to the first communication interface for the transmission of data;
a tank with a fuel; and
a sensor device configured to determine a fuel material property of the fuel of the refueling installation and to transmit the fuel material property to the motor vehicle via the first and second communication interfaces,

wherein the control unit of the motor vehicle is configured to control a vehicle component on the basis of the fuel material property determined by the sensor device,
wherein the control unit is configured to control a fuel intake quantity to the motor vehicle based on the fuel material property determined by the sensor device, and
wherein the control unit is additionally configured to control the fuel intake quantity to the motor vehicle based on a fill quantity in a vehicle fuel tank of the motor vehicle and a fuel material property of a fuel already located in the vehicle fuel tank of the motor vehicle.

2. The refueling system according to claim 1 , wherein the sensor device comprises a spectroscopic measuring instrument.

3. The refueling system according to claim 1 , wherein the sensor device is positioned and configured so as to determine the fuel material property of the fuel in the tank of the refueling installation.

4. A refueling system for a motor vehicle, the refueling system comprising:
a motor vehicle comprising:
a first communication interface; and
a control unit;

a refueling installation comprising:
a second communication interface, which has a communication connection to the first communication interface for the transmission of data;
a tank with a fuel; and
a sensor device configured to determine a fuel material property of the fuel of the refueling installation and to transmit the fuel material property to the motor vehicle via the first and second communication interfaces,

wherein the control unit of the motor vehicle is configured to control at least one vehicle component on the basis of the fuel material property determined by the sensor device, and
wherein the sensor device is configured to perform a dating of the fuel and/or to identify a renewability measure of the fuel based on the dating, and to transmit the dating of the fuel and/or the renewability measure of the fuel to the motor vehicle via the first and second communication interfaces.

5. The refueling system according to claim 1 , wherein the control unit is configured to determine a degree of mixture separability of the fuel already located in the vehicle fuel tank of the motor vehicle and the fuel of the tank of the refueling installation based on the fuel material property determined by the sensor device, the fuel material property of the fuel already located in the vehicle fuel tank of the motor vehicle and the fill quantity in the motor vehicle fuel tank, and, wherein, based on the degree of mixture separability, the control unit is configured to control the fuel intake quantity and/or to control a mixing device for mixing.

6. The refueling system according to claim 1 , wherein the control unit is configured to determine a maximum delivery quantity, and to control a fuel delivery such that the fuel intake quantity corresponds to the maximum delivery quantity.

7. A refueling system for a motor vehicle, the refueling system comprising:
a motor vehicle comprising:
a first communication interface; and
a control unit;

a refueling installation comprising:
a second communication interface, which has a communication connection to the first communication interface for the transmission of data;
a tank with a fuel; and
a sensor device configured to determine a fuel material property of the fuel of the refueling installation and to transmit the fuel material property to the motor vehicle via the first and second communication interfaces,

wherein the control unit of the motor vehicle is configured to control at least one vehicle component on the basis of the fuel material property determined by the sensor device, and
wherein the control unit is configured to adjust a stored service interval of the vehicle component of the motor vehicle based on the fuel material property determined by the sensor device.
