Definitions

  • the present invention relates to control of fuel usage in combustion engine powered machine, such as a vehicle, a stone crusher, a diesel power generator, or a diesel pump, for example control relating to amount of fuel used and fuel type used.
  • Some machines such as work machine vehicles, are shared between several operators, each operator operating the machine for a limited period of time.
  • the machine may be capable of operating on various fuel type, such as diesel and Hydrotreated Vegetable Oil (HVO), there may be legal or environmental reasons for using HVO instead of diesel.
  • HVO Hydrotreated Vegetable Oil
  • Price and availability often differ for various fuel types and the machines are thus sometimes fueled with another fuel type than the fuel type an operator is supposed to operate the machine on.
  • HVO Hydrotreated Vegetable Oil
  • an object of the present disclosure is to promote use of a correct type of fuel.
  • a further object is to promote fair use of fuel of a shared machine
  • a computer-implemented method for controlling fuel usage of a machine comprising: obtaining access information comprising information defining a first amount of fuel, obtaining fuel usage information of the machine during operation of the machine, the fuel usage information defining at least an amount of fuel used by the machine, and switching the machine to a restricted operation mode in response to the amount of fuel used by the machine exceeding the first amount of fuel.
  • the computer-implemented method may further comprise comparing information comprised in the access information to a predetermined fuel criterion/criteria and switching the machine to a normal operation mode if information comprised in the access information matches the predetermined fuel criterion/criteria.
  • the machine When an operator is to use the machine, the machine obtains the access information and subsequently checks the access information against a fuel criterion before enabling the machine for use by switching the machine to the normal operation mode. This mitigates any unauthorized use of the machine if the fuel criterion is not met and thus gives the operator an incentive to purchase only such fuel as required by the fuel criterion.
  • the predetermined fuel criterion may comprise a predetermined minimum amount of fuel, wherein the machine is switched to the normal operation mode only if the first amount of fuel exceeds the predetermined minimum amount of fuel.
  • the minimum amount of fuel could be set to zero but it is typically at least a few liters of fuel, such as five or ten liters of fuel. If the minimum amount is set to zero, any amount of fuel purchased, as defined by the access information, is sufficient and the check basically amounts to a check that access information is provided at all, i.e. the operator is at least someone with access to such access information and not just any person.
  • the access information may be provided with user information tied to a specific person, or legal entity.
  • a legal entity could purchase a lot of fuel of a specific type and then allocate access information to a specific person or machine according to a predicted daily use of the machine. This check also mitigates too short uses of the machine, reducing the risk of an operator having to drive home in a restricted operation mode which would lead to unnecessary unavailability of the machine for normal operation by others.
  • the access information may further comprise information defining a fuel type, wherein the predetermined fuel criterion further comprises a predetermined fuel type, and wherein the machine is switched to the normal operation mode only if the fuel type defined by the access information corresponds to the predetermined fuel type.
