| Abstract | Autonomous parking refers to driving a vehicle into a parking spot without manual operation. The emerging and prevailing methods are either effective on specific scenarios only or focus on overly simplified scenarios, lacking the capability to tackle general cases. In our viewpoint, a general parking motion planning problem is a dynamic optimization problem associated with complicated constraints. This paper proposes a unified formulation that can cover various kinds of parking scenarios when time-optimal solutions are pursued. First, we use differential equations to describe the kinematics of a car, and then use algebraic equalities/inequalities to restrict the car not collide with the parking slot frontiers. Through this, we formulate a time-optimal dynamic optimization (DO) problem that is identical to the original parking motion planning mission. Thereafter, the formulated DO is solved by a simultaneous approach. Although we pursue for time-optimal motions, this approach can be extended to consider other user-specific optimization criteria (such as minimum driving length or minimal fuel usage) with almost none additional effort. |

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.
