| Abstract | The performance of the torque control and distribution is a critical problem that can affect the stability, safety and energy efficiency of a rear-wheel independent drive (RWID) electric vehicle (EV). This study proposes a model adaptive torque control and distribution method for RWID EVs. First, the torque control and distribution problem is analysed in detail. Then an RWID EVs’ longitudinal model is built and a torque control and distribution scheme is proposed. To avoid the over-actuation and the under-actuation of the powertrain system, a controller is designed based on the longitudinal model to adaptively control the driving torque. To comprehensively consider the stability and safety, an error reconstruction strategy based on the fuzzy logic theory is proposed to evaluate the errors in the side slip angle and in the yaw rate. In order to accurately distribute the driving torque to the rear wheels, a torque distribution controller is designed. Finally, the proposed method is validated on a co-simulation platform, and the simulation results demonstrate the excellent performance of the proposed method for RWID EVs’ torque control and distribution compared with the counterparts of fuzzy logic direct yaw-moment control and two-loop torque distribution and control. |

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.
