The "Drive-cycle" basically is the representative of the road. Drive cycles are used to reduce the expense of on road tests, time of test and fatigue of the test engineer. The whole idea is to bring the road to the test lab (a chassis dynamo-meter) or to the computer simulation. Two kinds of drive cycle can be made.
The "city" driving program of the EPA Federal Test Procedure is identical to the UDDS plus the first 505 seconds of an additional UDDS cycle. [5] [6] EPA FTP-75 driving cycle. Then the characteristics of the cycle are: Distance travelled: 11.04 miles (17.77 km) Duration: 1874 seconds; Average speed: 21.2 mph (34.1 km/h)
The light generally [3] has two stages: steady (indicating a minor repairable fault, but service on the vehicle is strongly recommended as soon as possible to prevent future damage) and flashing (indicating a severe fault and an emergency that makes the vehicle unsafe to drive and it is strongly recommended that the vehicle gets mechanical ...
OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
For example, the vehicle computer can identify past driving history as one particular representative cycle (say, FTP-75) and use known information from FTP-75 to improve vehicle performance. This type of control strategy is most useful for hybrid vehicles where the control strategy has a much greater effect on vehicle performance than with a ...
