| Abstract | In this paper, a control strategy based on transmission efficiency for a dual mode power split-type hybrid electric vehicle (HEV) that considers mechanical loss is developed. Two control strategies, based on the transmission efficiency for the dual mode PST, that consider the TM loss are proposed. An optimal operation line (OOL) control strategy is developed to maintain high engine thermal efficiency by controlling the engine operation point on the OOL of the engine, and by selecting the power split mode — whichever has higher transmission efficiency at a given speed ratio (SR). A SR control strategy is proposed to obtain higher transmission efficiency by shifting the engine operation point. Using the TM loss and the proposed control strategies, a vehicle performance simulation is conducted to evaluate the performance of the two control strategies for dual mode PST, and to investigate the fuel economy for the dual mode PST. It is found from the simulation results that for the SR control strategy, engine efficiency decreased because the engine was operated out of the OOL. However, the transmission efficiency of the dual mode PST increased because the PST was operated near the mechanical point where the PST showed the highest transmission efficiency. Consequently, the fuel economy of the SR control strategy was improved by 3.8% compared to that of the OOL control strategy. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
