Predictive energy management control scheme for a vehicle including a hybrid powertrain system

摘要

A method for controlling a vehicle having a hybrid powertrain includes monitoring vehicle navigation and traffic patterns associated with a predicted travel path. It extends the powertrain instantaneous controller into a predictive control framework, and utilizes previewed traffic and geographic information based on on-board sensing and navigation information. An impending road load is predicted from which a fuel cost factor is optimized under a model predictive control framework. A state-of-charge trajectory is predicted from the impending road load and operation of the hybrid powertrain system is controlled in response thereto.
