Evaluating Hybrid Vehicle Concepts Using Optimal Control and Generic Powertrain Modelling
Published April 19, 2004 by University of Salerno in Italy
This paper describes how operational cost of various vehicle concepts can be estimated using optimal control based on non-linear programming. The advantage of comparing optimal results is that vehicle hardware concepts can be evaluated and compared without having to design any control system. Since the method should be applicable to all kinds of hybrid and conventional vehicles, the main focus lies on a modelling method that produces dynamic models appropriate for optimal control implementation. Results show that the method allows complex powertrain systems to be modeled in a way suitable for control optimization.
