Android application which analyzes the fuel consumption of a vehicle - using input from a Bluetooth ODB dongle - and gives suggestions how to improve it.
(a) a group of parameters which are readout in real time by OBD system, whose values are
changing and depend on the driver’s requirements and road resistance. These parameters fall
into group of characteristic parameters that were used during the implemented investigation,
and they are (a1):
– calculated load value L,
– throttle opening Ø,
– engine speed n, and
– vehicle speed v.
Acquired values of the mentioned parameters, describing current mode of motion, are
used directly by the model algorithm in order to recommend the optimum gear.
(b) group of the data and criterion parameters that are determined by the technical characteristics
of vehicle, its engine, transmission and OBD system, and which affect, directly or indirectly,
the values of criteria which are an integral part of the algorithm structure. The data refer to
the values declared by a manufacturer and are considered as constants not derived, and they
are (b1):
– gear ratios ii,
– final drive ratio io,
– dynamic rolling radius rd, and
– list of characteristic parameters provided by OBD system of the significance for the
model.
