That’s a great question! Here is a somewhat technical explanation of how your car reports fuel used. It’s through something called the OBD-II port – where you put the OReGO mileage recording device.
An on-board diagnostics port, known as OBD-II, is required on all automobiles and light trucks in the United States from 1996 onward. OBD-II is a set of specifications for monitoring and reporting engine performance in vehicles. Diesel (compression ignition) vehicles were not required to support OBD until 2004.
Prior to OBD, auto manufacturers did not standardize diagnostic trouble codes, known as DTC’s. OBD-I began the standardization of DTC’s and OBD-II added specific tests to determine the vehicles emission performance. OBD-III adds more features, and is in the regulatory development phase now.
The Society of Automotive Engineers (SAE) works with the automotive industry and regulatory bodies to develop standards for on-board diagnostics.
The OBD-II can capture data about fuel usage and mileage travelled via the mileage reporting device (MRD) that is used in the road usage charge program. The MRD transmits that information to your account manager to calculate your total road usage charge, minus fuel tax credits.
The MRD can measure fuel consumption by obtaining data from the engine. Some of this information comes from internal sensors that include the Mass Air Flow (MAF) sensor. The MAF sensor delivers a precise measure of the flow rate of air. This, combined with the air/fuel ratio, provides a precise measurement in determining the fuel consumption for trips. The MRD calculates miles traveled by measuring the amount of time your vehicle’s engine is on, over the speed of your vehicle. If you choose a commercial account manager, such as Verizon or Azuga, the mileage-reporting device operates as a scan tool to provide you with even more services. This may include giving you trouble codes and working as a trip computer.
So that’s why you don’t need to turn in receipts with OReGO – the vehicle reports how much fuel you’ve used! Pretty smart, huh?
