Abstract
The invention relates to a method for operating a fuel supply pump of a vehicle, the vehicle comprising a combustion engine system and a gearbox, the method comprising the steps of: determining one or more operational values of at least one operational parameter of the combustion engine system; determining a reduction of a fuel provision rate to the combustion engine system; determining whether a gear step change of the gearbox is at hand, on the basis of the determined one or more operational values of the at least one operational parameter; and in case a gear step change of the gearbox is at hand, controlling operation of the fuel supply pump so as to maintain fuel supply pump speed.
Claims14
A method for operating a fuel supply pump of a vehicle, the vehicle comprising a combustion engine system and a gearbox, the method comprising the steps of:
- determining one or more operational values of at least one operational parameter of the combustion engine system;
- determining a reduction of a fuel provision rate to the combustion engine system;
- determining whether a gear step change of the gearbox is at hand, on the basis of the determined one or more operational values of the at least one operational parameter;
- and
- in case a gear step change of the gearbox is at hand, controlling operation of the fuel supply pump so as to maintain fuel supply pump speed.
A system for operating a fuel supply pump of a vehicle, the vehicle comprising a combustion engine system and a gearbox, the system comprises:
- means being arranged for determining one or more operational values of at least one operational parameter of the combustion engine system;
- means being arranged for determining a reduction of a fuel provision rate to the combustion engine system;
- means being arranged for determining whether a gear step change of the gearbox is at hand, on the basis of the determined one or more operational values of the at least one operational parameter;
- and
- means being arranged for, in case a gear step change of the gearbox is at hand, controlling operation of the fuel supply pump so as to maintain fuel supply pump speed.
A vehicle comprising a system for operating a fuel supply pump of a vehicle, the vehicle comprising a combustion engine system and a gearbox, the system comprises:
- means being arranged for determining one or more operational values of at least one operational parameter of the combustion engine system;
- means being arranged for determining a reduction of a fuel provision rate to the combustion engine system;
- means being arranged for determining whether a gear step change of the gearbox is at hand, on the basis of the determined one or more operational values of the at least one operational parameter;
- and
- means being arranged for, in case a gear step change of the gearbox is at hand, controlling operation of the fuel supply pump so as to maintain fuel supply pump speed.
A non-transitory computer readable media comprising program instructions stored thereon for operating a fuel supply pump of a vehicle, the vehicle comprising a combustion engine system and a gearbox, said computer program instructions configured to cause one or more computing devices to perform the following operations:
- determine one or more operational values of at least one operational parameter of the combustion engine system;
- determine a reduction of a fuel provision rate to the combustion engine system;
- determine whether a gear step change of the gearbox is at hand, on the basis of the determined one or more operational values of the at least one operational parameter;
- and
- in case a gear step change of the gearbox is at hand, control operation of the fuel supply pump so as to maintain fuel supply pump speed.
