Abstract
Legislation claims a sustainable handling of existing resources. For this reason all newly registered vehicles must emit less then maximum 130 g/km CO2 on average by 2015. Car manufactures are therefore forced to use new approaches in the fields of propulsion technology and assistance systems. For the development of such efficient vehicles new methods are needed which exceed the determination of the consumption at the chassis dyno or the road test. It is necessary that the results concerning the real consumption as well as the distribution of the energy losses are available at an early stage of the development cycle. Furthermore, the safeguarding of the functionality of new highly networked powertrain systems is an important aspect. Here, the energy flux analysis at the vehicle test bed comes into place. As integrated validation environment it will be referred to as Function and Energy Flux Simulator (FES). With FES, real driving situations are emulated by means of a vehicle dynamics simulation. With dynamometers the occurring wheel torques are impressed on the vehicle. At the FES, driving scenarios and the environmental conditions are exactly reproducible so that the results are significant. In addition, a continuous superordinate process for validating the energy efficiency which reaches from the office simulation to the trial at the test bed as well as to the road drive with portable measurement systems was set up.
