What is the parameter that can be used to measure the fuel consumption?
Fuel economy is the distance travelled per unit volume of fuel used; for example, kilometres per litre (km/L) or miles per gallon (MPG), where 1 MPG (imperial) ≈ 0.354006 km/L. In this case, the higher the value, the more economic a vehicle is (the more distance it can travel with a certain volume of fuel).
What data can you get from obd2?
OBD-II offers a standard way to access many types of data, including:
- Real-time parameters: RPM, speed, pedal position, spark advance, airflow rate, coolant temperature, etc.
- Status of “Check Engine” light.
- Emission readiness status.
- Freeze frame: a “snapshot” of parameters at the time a trouble event has occurred.
How are values retrieved from OBD-II sensor diagnostics?
The values are retrieved through the OBD-II diagnostics protocol and they are related with the vehicle operation and with the fuel consumption. As proof of concept, focused experimentation has taken place, through a 5 km trip with low and heavy traffic. Values retrieved from the OBD-II scanner are presented and discussed.
What are the parameters of OBD auto Doctor?
OBD Auto Doctor supports the following standard OBD-II parameters (PIDs) as defined in SAE J1979 AUG2014. The actual list of available parameters is vehicle specific. Only the parameters supported by the car will be shown in the software.
Where can I find OBD data for my car?
Consumption calculation Consumption can be evaluated from OBD data directly from a parameter (PID) of SAEJ1979 standard [7] (or using a non-standard car manufacturer parameter) or if not available, from intake airflow sensor and air/fuel ratio sensor.
What does OBD stand for in vehicle category?
As discussed, vehicle electronic units communicate with each other through a network (CANBus or similar) for monitoring and data transfer (errors, value adjustments). OBD is a diagnostic and reporting capability of a vehicle allowing the vehicle operator or technician to access the status of the engine subsystems.
