Abstract
A method is provided for estimating a range for a vehicle, where the vehicle includes a combustion engine and a fuel supply system associated with the combustion engine. Vehicle also includes a first main tank for receiving fuel, and a first fuel pump for transfer of fuel from the first main tank to the fuel supply system. The method estimates a range for the vehicle based on data relating to the road ahead of the vehicle and a first measure of residual fuel in the first main tank. The method further controls a required fuel reserve based on the data relating to the road ahead of the vehicle.
Claims18
A method for estimating a range of a distance that a vehicle may travel without refueling, wherein said vehicle comprises a combustion engine and a fuel supply system associated with said combustion engine, wherein the vehicle also comprises a first main tank for receiving fuel, and a first fuel pump for transfer of fuel from said first main tank to said fuel supply system, wherein the method comprises:
- based on data relating to the road ahead of the vehicle and a first measure of a residual fuel in said first main tank, estimating a range for said vehicle;
- based on said data relating to the road ahead of the vehicle, controlling a required fuel reserve.
A computer program product for estimating a range a range of a distance that a vehicle may travel without refueling, wherein said vehicle comprises a combustion engine and a fuel supply system associated with said combustion engine, wherein the vehicle also comprises a first main tank for receiving fuel, and a first fuel pump for transfer of fuel from said first main tank to said fuel supply system, said computer program product located on a non-transitory computer readable medium, comprising instructions for operation by a computing device, said instructions comprising:
- instructions configured for estimating a range for said vehicle based on data relating to the road ahead of the vehicle and a first measure of a residual fuel in said first main tank;
- and
- instructions configured for controlling a required fuel reserve based on said data relating to the road ahead of the vehicle.
A system for estimating a range of a distance that a vehicle may travel without refueling, wherein said vehicle comprises a combustion engine and a fuel supply system associated with said combustion engine, wherein the vehicle also comprises a first main tank for receiving fuel and a first fuel pump for transfer of fuel from said first main tank to said fuel supply system, wherein the system comprises a processing device configured for:
- based on data relating to the road ahead of the vehicle and a first measure of a residual fuel in said first main tank, estimating a range for said vehicle;
- and
- based on said data relating to the road ahead of the vehicle, controlling a required fuel reserve.
A vehicle comprising a combustion engine, a fuel supply system associated with said combustion engine, a first main tank for receiving fuel and a first fuel pump for transfer of fuel from said first main tank to said fuel supply system, said combustion engine further comprising a processing device for estimating a range of a distance that a vehicle may travel without refueling, said processing device configured for:
- based on data relating to the road ahead of the vehicle and a first measure of a residual fuel in said first main tank, estimating a range for said vehicle;
- and
- based on said data relating to the road ahead of the vehicle, controlling a required fuel reserve.
