Abstract
The invention relates to a method for a communication between a fueling device (2) and a vehicle (4), having the steps of coupling the fueling device to a tank (6) of the vehicle by means of a fuel hose (10), providing pressurized fuel to the fuel hose, varying the pressure on the fuel hose by superimposing a specified base pressure with a pressure sequence in order to modulate a first signal to be transmitted, detecting the pressure being applied to the fuel hose by means of the vehicle, and extracting the first signal to be transmitted from the detected pressure.
Claims10
A method for a communication between a fueling device (2) and a vehicle (4), having the steps of:
- coupling (28) the fueling device (2) to a tank (6) of the vehicle (4) by means of a fuel hose (10),
- providing (30) pressurized fuel to the fuel hose (10),
- varying (32) the pressure on the fuel hose (10) by superimposing a specified base pressure (22) with a pressure sequence in order to modulate a first signal to be transmitted, and
- detecting (34) the pressure being applied to the fuel hose (10) by means of the vehicle (4), and extracting (36) the first signal to be transmitted from the detected pressure.
A system (5) for a communication between a fueling device (2) and a vehicle (4), wherein the fueling device (2) comprises a fuel hose configured to be coupled to a tank (6) of the vehicle (4), wherein the fueling device (2) is configured to provide a fuel that has been subjected to variable pressure through the fuel hose (10), wherein the fueling device (2) comprises a first control unit (12), which is configured to cause (32) the pressure to vary on the fuel hose (10) by superimposing a specified base pressure (22) with a pressure sequence (24) in order to modulate a first signal to be transmitted, wherein the vehicle (4) comprises a second control unit (14), which is configured to detect the pressure being applied to the fuel hose (10) via a tank pressure sensor (16) and to extract the first signal to be transmitted from the detected pressure.
