Driving Cycle Design
The "Drive-cycle" basically is the representative of the road. Drive cycles are used to reduce the expensive 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. One is DISTANCE DEPENDENT (SPEED vs DISTANCE vs ALTITUDE) and the other one is TIME DEPENDENT (SPEED VS TIME VS GEAR SHIFT). The DISTANCE DEPENDENT is the actual replica of the test road. whereas TIME DEPENDENT is the compressed version of the actual time taken to conduct the test on road. Examples of TIME DEPENDENT drive cycles are European NEDC cycle, FTP-75. TIME DEPENDENT drive cycles are used specifically for chassis dynamo meter testing because in a short time the results can be availed and repeated tests can be done easily.

Famous quotes containing the words driving, cycle and/or design:
“The Westerly Wind asserting his sway from the south-west quarter is often like a monarch gone mad, driving forth with wild imprecations the most faithful of his courtiers to shipwreck, disaster, and death.”
—Joseph Conrad (1857–1924)
“Oh, life is a glorious cycle of song,
A medley of extemporanea;
And love is a thing that can never go wrong;
And I am Marie of Roumania.”
—Dorothy Parker (1893–1967)
“The reason American cars don’t sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. That’s why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
