Abstract

This paper describes a modeling and design approach in finding the optimal controller for a low-cost hybrid drive train on a pre-defined driving cycle. The hybrid drive train is characterized by a small energy capacity (flywheel) and discrete shifts between operation modes, due to the use of clutches. The main design criterion, is the minimization of the overall fuel consumption, whereas constraints are defined to describe the systems dynamics, kinematics and constraints. In addition, comfort criteria are defined as constraints, to avoid uncomfortable driving conditions. These criteria are used to find the optimal sequence of driving modes and generated engine torque over a defined driving cycle. Simulations show a fuel saving potential of 22% to 39%, dependent on the chosen driving cycle.
