| Abstract | This paper presents a predictive energy management for plug-in hybrid vehicles, feasible for the implementation on an electronic control unit. An optimal reference trajectory for the battery's state of charge is calculated by solving a hybrid optimal control problem that considers continuous controls as well as discrete decisions, such as the switching between drive modes. The problem is solved via an indirect variation of extremals approach, expanded for hybrid systems. To decrease calculation time, information necessary for solving the problem is calculated offline and stored in lookup tables. The information necessary for the formulation of the hybrid optimal control problem are obtained using information from modern navigation systems for each segment of the route. A driver model transforms this set of information into a continuous driving profile that contains all necessary information for solving the hybrid optimal control problem. A PI-controller is implemented to follow the reference trajectory of the battery's state of charge. The controller output is an offset to the costate obtained from the solution of the hybrid optimal control problem. The energy management was implemented in a pilot-production plug-in-hybrid vehicle. Results obtained from real world measurements are presented as well as simulation results to investigate the energy management's robustness. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
