The global automotive industry has been witnessing a transformation over the last decade with digital communication technologies making rapid inroads in vehicles. The world is moving towards the concept of connected transportation that focuses on providing enhanced connectivity like vehicles communicating with each other to know their presence, real-time communication facility to the occupants of the vehicle. This functionality is enabled by variety of technologies like vehicle to vehicle communication, vehicle to infrastructure, vehicle telematics, and vehicle informatics that provide various services such as real-time street updates, smart routing and tracking, roadside assistance in case of accidents, automatic toll transactions, automatic parking/parking management, on-board entertainment, and much more.
This paper discusses the need for relevant and economic solutions, emerging trends and accompanying challenges that arise with growing complexity and evaluates the best-possible mechanism to overcome these challenges. It also delves into the various components that get into the connected car gateway/wireless gateway beginning with analysis of the software components, complexities of a modern connected car gateway system and optimization possibilities. It concludes with a view on the existing supply chain precision and the way forward.
