Networks and Communications for the Connected Car

Availability

This module is only available to students on the MSc in Smart, Connected, and Autonomous Vehicles and as part of the Part Time TAS JLR scheme.

Introduction

This module aims to provide the students with an up to date, comprehensive knowledge of the main wired and wireless communications technologies that are used, or will be used, in current and future production consumer vehicles.

Through providing a knowledge base of core telecommunications theories, the student is taken forward into the application domain, such that the various wired and wireless technologies in the context of the automotive space is understood. Key concepts of theory Vs application are discussed based upon the inference and understanding of the performance of the technologies both at the component and system level. Topics are introduced from both the theoretical and practical viewpoints to encourage independent critical evaluation of the subject matter.

Objectives

Upon successful completion participants will be able to:

  • Critically evaluate different communication systems and how they might be integrated together within a connected and/or autonomous system.
  • Infer how the relative communications technologies interact with both the user, the vehicles control and the wider network.
  • Evaluate a complete communication system within the wider automotive eco-system and understand what is currently considered as state-of-the-art, with an enhanced research view of the future
  • An ability to apply relevant practical communications techniques appropriately and understand how their results may be used to inform judgements and develop and advance ideas and/or practice.
  • Demonstrate the ability to design communication systems to support connectivity aspect of connected and/or autonomous systems within the backdrop of Intelligent Transportation Systems network.
  • A comprehensive understanding of and competence in the use of appropriate channel modelling tools and techniques for the purpose of system performance prediction.
