Driving cycle
A driving cycle is a series of data points representing the speed of a vehicle versus time.
Driving cycles are produced by different countries and organizations to assess the performance of vehicles in various ways, for example, fuel consumption, electric vehicle autonomy and polluting emissions.
Fuel consumption and emission tests are performed on chassis dynamometers. Tailpipe emissions are collected and measured to indicate the performance of the vehicle.
Another use for driving cycles is in vehicle simulations. For example, they are used in propulsion system simulations to predict performance of internal combustion engines, transmissions, electric drive systems, batteries, fuel cell systems, and similar components.
Some driving cycles are derived theoretically, as in the European Union, whereas others are direct measurements of a representative driving pattern.
There are two types of driving cycles:
The American FTP-75, and the unofficial European Hyzem driving cycles are transient, whereas the Japanese 10-15 Mode and JC08 cycles are modal cycles.
Some highly stylized modal driving cycles such as the European NEDC were designed to fit a particular requirement, but bear little relation to real world driving patterns. On the contrary, the current Worldwide harmonized Light vehicles Test Procedure (WLTP) strives to mimic real world driving behavior. The most common driving cycles are the WLTP, NEDC, SORDS and the FTP-75, the latter corresponding to urban driving conditions solely.
