The paper focusses on the control strategy problem for hybrid parallel powertrains. Some works are available on this problem. On one hand they are based on instantaneous optimization /Paganelli 1999/ /Seiler & Schroder 1998/, or dedicated to a specific powertrain /Yamaguchi & al. 1996/. These methods are mainly designed for consumption minimization and can be used for real time application. Of course, they cannot allow to reach a global optimum. On the other hand, global optimization works are also discussed in /Delprat & al. 1999/ and Rimaux & al. 1999/. Results show a real improvement according to the preceding methods on a given cycle. Nevertheless, those methods requires a lot of calculation and no real time strategy can be derived from them. However, global optimization methods can provide optimal results that can be used as a basis for evaluating the real time control strategy performance.
