Driving cycle

A driving cycle consists of starting the engine, possibly a test drive (with a share of idling, partial load, constant driving, and overrunning phase) and the time between stopping the engine and starting again. For the purpose of shedding/healing faults, the driving cycle must sometimes include performing the relevant diagnosis.
