In view of the finiteness of fossil energy sources, the CO2 discussion and political constraints regarding emission limitations of motor vehicles, the OEMs (Original Equipment Manufacturers) have focused on the development of alternative drive concepts for several years. The parallel hybrid drive, already on the market in different development stages, is one of these concepts. The published values in terms of fuel consumption are determined in standardised cycles, e.g. the NEDC (New European Driving Cycle). These values, however, do not correlate sufficiently with the ones determined in practice. In this regard, a holistic approach will be presented by means of which the driver behaviour in real traffic can be determined and represented in a simulation. This is based on the so-called DRV parameter space which is defined by the three variables Driver (customer), Road (driving environment) and Vehicle. The driver is differentiated in terms of driving style. 'Vehicle' takes the system behaviour of the hybrid drive train in the vehicle into account and the driving environment describes where the vehicle is driven (road, traffic management etc.). In the scope of the present paper, the application of the DRV method for quantifying the customer benefit in a parallel HEV is compared to a conventional vehicle in terms of fuel consumption.
