Abstract
A method is provided for refueling a motor vehicle. The method include the steps of: acquiring at least one signal, wherein the signal contains information as to whether the motor vehicle has at least one device for preventing follow-up refueling; and providing fuel in accordance with the acquired signal.
Claims13
A method for refueling a motor vehicle, comprising:
- detecting, by a filling station, at least one signal, wherein the signal contains an item of information as to whether the motor vehicle has at least one device for preventing a follow-up refueling, the device for preventing the follow-up refueling ascertaining a difference between a current fuel temperature in a pressure vessel of the motor vehicle and an ambient temperature, and preventing the follow-up refueling when the difference is greater than a limiting value;
- and
- providing, by the filling station, fuel to the motor vehicle in dependence on the detected signal.
A method for refueling a motor vehicle, comprising:
- detecting, by a filling station, at least one signal, wherein the signal contains an item of information as to whether the motor vehicle has at least one device for preventing a follow-up refueling;
- and
- providing, by the filling station, fuel to the motor vehicle in dependence on the detected signal, wherein
- the fuel is provided at different, non-zero, flow rates in dependence on the at least one signal, and
- wherein the fuel is provided at a first flow rate if the signal contains the information that the motor vehicle:
- (i) does not have a device for preventing a follow-up refueling,
- (ii) has a defective device for preventing a follow-up refueling, or
- (iii) no signal was detected;
- wherein the fuel is provided at a second flow rate if the signal contains the information that the motor vehicle has the at least one device for preventing a follow-up refueling, and
- wherein the first flow rate is less than the second flow rate.

A method for refueling a motor vehicle, comprising:
- detecting, by a filling station, at least one signal, wherein the signal contains an item of information as to whether the motor vehicle has at least one device for preventing a follow-up refueling;
- and
- providing, by the filling station, fuel to the motor vehicle in dependence on the detected signal, wherein
- the fuel is provided at different, non-zero, flow rates in dependence on the at least one signal, and wherein
- during refueling the signal is still detected,
- after an abort or an interruption of the signal during the refueling, the refueling is continued, and wherein
- a target fill level to be reached is decreased by 2% to 30% or by 10% to 20%.
4 more elements
A filling station, comprising:
- a detection device for detecting at least one signal of a motor vehicle, wherein the signal contains information as to whether the motor vehicle has at least one device for preventing a follow-up refueling;
- and
- a provision device for providing fuel in dependence on the detected signal,
- wherein the fuel is provided at a first flow rate if the signal contains the information that the motor vehicle:
- (i) does not have a device for preventing a follow-up refueling,
- (ii) has a defective device for preventing a follow-up refueling, or
- (iii) no signal was detected;
- wherein the fuel is provided at a second flow rate if the signal contains the information that the motor vehicle has the at least one device for preventing a follow-up refueling, and
- wherein the first flow rate is less than the second flow rate.
6 more elements
A motor vehicle, comprising:
- at least one device for preventing a follow-up refueling;
- and
- at least one device for providing a signal to a filling station, wherein the signal contains information usable by the filling station as to whether the motor vehicle has the at least one device for preventing a follow-up refueling,
- wherein the device for preventing the follow-up refueling is configured to:
- i) ascertain a difference between a fuel temperature in a pressure vessel and an ambient temperature, and
- ii) prevent a follow-up refueling when the difference between the fuel temperature in the pressure vessel and the ambient temperature is greater than a limiting value.
3 more elements
A computer product comprising a non-transitory computer-readable storage medium, on which program instructions are stored, which, upon execution by a microprocessor, carries out the acts of:
- detecting, by a filling station, at least one signal, wherein the signal contains an item of information as to whether the motor vehicle has at least one device for preventing a follow-up refueling;
- and
- providing, by the filling station, fuel to the motor vehicle in dependence on the detected signal,
- wherein the fuel is provided at a first flow rate if the signal contains the information that the motor vehicle:
- (i) does not have a device for preventing a follow-up refueling,
- (ii) has a defective device for preventing a follow-up refueling, or
- (iii) no signal was detected;
- wherein the fuel is provided at a second flow rate if the signal contains the information that the motor vehicle has the at least one device for preventing a follow-up refueling, and
- wherein the first flow rate is less than the second flow rate.
