E-DRIVING CYCLES

vehicles are largely dependent on
the load requirements from driving
cycles. For example batteries can be
developed with regard to size and
performance to suit a vehicle’s area
of application.
Speed-time profile
A driving cycle is a speed-time
profile with the aim of creating
comparability between vehicles.
Gradient can also be plotted using
vehicle data. Driving cycles help to
evaluate vehicles in a developmentoriented
way, which is important for
component selection and
performance dimensioning. In
Europe, the New European Driving
Cycle (NEDC) was used as the
measurement cycle until September
2017. Since September 2017, the
newly developed cycle Worldwide
Harmonized Light-Duty Vehicles
Test Procedure (WLTP) has replaced
the NEDC and has since been valid
as a uniform standard for all vehicles
across all countries. Another type of
driving cycle for research and
development is measured driving
cycles, in which the vehicle data is
