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.

1. 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
1. 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. 2. The method according to claim 1, wherein said first fuel pump consists of a fuel pump powered by an electric engine. 3. The method according to claim 1, wherein said vehicle also comprises a transfer tank, arranged between said fuel supply system and said first main tank, wherein the method comprises supplying fuel to said transfer tank from said first main tank before transferring to said fuel supply system, and wherein said transfer tank constitutes a smaller tank compared to said first main tank. 4. The method according to claim 3, wherein said transfer tank consists of a tank with a height, which consists of a higher height compared to the width and the depth. 5. The method according to claim 3, wherein the size of the transfer tank is in the range 15-50 liters, or of a size which, in relation to the total volume of one or several main tanks, constitutes a volume within the range 1-10% or 1-5% of the total volume of said main tanks. 6. The method according to claim 3, wherein fuel is supplied to said fuel supply system from said transfer tank via a second fuel pump. 7. The method according to claim 6, wherein said second fuel pump consists of an electrically powered fuel pump. 8. The method according claim 3, further comprising: estimating said first measure of residual fuel in said first main tank, at least partly based on a rate at which said transfer tank is filled with fuel from said first main tank. 9. The method according to claim 3, also comprising estimating said range, at least partly based on the expected possibilities of filling said transfer tank. 10. The method according to claim 1, further comprising: estimating said first measure of residual fuel in said first main tank, at least partly based on a float arranged in said first main tank. 11. The method according to claim 1, further comprising: estimating said first measure of residual fuel in said first main tank, at least partly based on the size of a drive current for an electric motor that powers said first fuel pump. 12. The method according to claim 1, wherein said vehicle comprises at least a first and a second main tank, wherein said first and second main tanks are in fuel transferring connection with each other, and wherein the method comprises transfer of fuel from said first and second main tanks to said transfer tank, via said first fuel pump. 13. The method according to claim 1, wherein the method is carried out when the expected residual amount of fuel in said first main tank falls below a first amount of fuel. 14. 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; andinstructions configured for controlling a required fuel reserve based on said data relating to the road ahead of the vehicle. 15. 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; andbased on said data relating to the road ahead of the vehicle, controlling a required fuel reserve. 16. A system according to claim 15 further comprising a computer program product located on a non-transitory computer readable medium, comprising instructions for operation by said processing device to cause said processing device to: estimate 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; andcontrol a required fuel reserve based on said data relating to the road ahead of the vehicle. 17. 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; andbased on said data relating to the road ahead of the vehicle, controlling a required fuel reserve. 18. A vehicle according to claim 17 further comprising a computer program product located on a non-transitory computer readable medium, comprising instructions for operation by said processing device to cause said processing device to: estimate 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; andcontrol a required fuel reserve based on said data relating to the road ahead of the vehicle.
