Division 2 DefinitionsF1

‘On-board Fuel and/or Energy Consumption Monitoring Device’ (‘OBFCM device’) means any element of design, either software and/or hardware, which senses and uses vehicle, engine, fuel and/or electric energy parameters to determine and make available at least the information laid down in point 3, and store the lifetime values on board the vehicle.

‘Lifetime’ value of a certain quantity determined and stored at a time t shall be the values of this quantity accumulated since the completion of production of the vehicle until time t.

‘Engine fuel rate’ means the amount of fuel injected into the engine per unit of time. It does not include fuel injected directly into the pollution control device.

‘Vehicle fuel rate’ means the amount of fuel injected into the engine and directly into the pollution control device per unit of time. It does not include the fuel used by a fuel operated heater.

‘Total Fuel Consumed (lifetime)’ means the accumulation of the calculated amount of fuel injected into the engine and the calculated amount of fuel injected directly into the pollution control device. It does not include the fuel used by a fuel operated heater.

‘Total Distance Travelled (lifetime)’ means the accumulation of the distance travelled using the same data source that the vehicle odometer uses.

‘Grid energy’ means, for OVC-HEVs, the electric energy flowing into the battery when the vehicle is connected to an external power supply and the engine is turned off. It shall not include electrical losses between the external power source and the battery.

‘Charge sustaining operation’ means, for OVC-HEVs, the state of vehicle operation when the REESS state of charge (SOC) may fluctuate but the intent of the vehicle control system is to maintain, on average, the current state of charge.

‘Charge depleting operation’ means, for OVC-HEVs, the state of vehicle operation when the current REESS SOC is higher than the charge sustaining target SOC value and, while it may fluctuate, the intent of the vehicle control system is to deplete the SOC from a higher level down to the charge sustaining target SOC value.

‘Driver-selectable charge increasing operation’ means, for OVC-HEVs, the operating condition in which the driver has selected a mode of operation, with the intention to increase the REESS SOC.
