Abstract
Model-based approach is applied to solve two practical issues in automotive powertrain control; optimizing gear shift patterns to balance driving performance and fuel economy, and smoother gear shifting to improve riding comfort. A shift scheduling method based on real-time optimization is proposed and evaluated to show its effectiveness for flexible tuning between performance and fuel economy. For smooth gear shifting, a collaborative control scheme between engine and automatic transmission (AT) gearbox is discussed to aim for a more fundamental torque control of the powertrain. To facilitate the model-based approach, an AT gearbox model is devised using hybrid systems techniques to represent the discrete-event nature of automatic transmissions.
