MODERN VEHICLE SYSTEMS DESIGN - 2024/5

Module code: ENG3170

Module Overview

In the realm of transportation, a firm grasp of vehicle dynamics, brake systems, and powertrain systems is of paramount importance. These pillars underpin the very essence of modern automotive engineering, shaping the way vehicles move, slow down, and utilise energy.

Understanding vehicle dynamics enables engineers to optimise handling, stability, and manoeuvrability, translating into safer and more enjoyable driving experiences. Brake systems, beyond mere stopping power, ensure road safety and vehicle stability, and require intricate knowledge for effective design and operation. Powertrain systems, including innovative electric and hybrid technologies, drive the propulsion of vehicles, influencing efficiency and sustainability.

Throughout the weeks the module will explore the intricate mechanics underpinning vehicle motion and how to model it in all its relevant components. Braking systems will be fully described and information will be provided on how to properly size them, based on specific targets in terms of vehicle deceleration and stability. Finally electric and hybrid electric powertrains will be described and analysed, including concepts such as regeneration and efficiency.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate understanding of scientific principles, methodologies and mathematical methods as well as the ability to describe particular systems and processes. The pieces of coursework test analytical and simulation skills, report writing as well as critical analysis capability of design solutions found in industry.

 The summative assessment for this module consists of:


  • Coursework 1, submitted as a formal report, focusing on learning outcomes 1, 2, 3, and 6  

  • Coursework 2, submitted as a formal report, focusing on learning outcomes 4 and 5



The formative assessment consists in active discussions during the lectures, either triggered by the module conveyer or directly by the students. Moreover tutorials solutions are shown and discussed in the tutorial sessions and provided afterwards.

Feedback is provided during all the tutorial sessions, while the students solve the exercises independently and the module conveyer is at hand to clarify doubts and reiterate methodologies.

Module aims

  • A systematic understanding and critical awareness of the importance of individual components and systems of modern road vehicles.
  • A knowledge of the design methods of vehicle cornering response.
  • An understanding of the energy efficiency characteristics and constraints of modern hybrid electric and fully electric powertrain solutions.
  • A knowledge of basic calculation techniques relating to vehicle dynamics.

Methods of Teaching / Learning

The learning and teaching strategy is designed to:


  • Give students the necessary information to understand modern road vehicles behaviour and modeling

  • Get students acquaint with methodologies for selecting, designing and analysing vehicles braking systems components

  • Allow students to practise the methodologies for vehicle dynamics analysis learned in the module via dedicated tutorial sessions

  • Get students equipped with basic understanding of software to tackle some of the presented analysis methods via the coursework, in a learning by doing approach

  • Expose students to professional practice on the topic of vehicle dynamics control and active vehicle safety systems via an active discussion based on research work and scientific papers

  • Give students the necessary background on modern fully-electric and hybrid-electric powertrain systems



The learning and teaching methods include:


  • Lectures (in-person): where the content that is assessed is presented

  • Seminars (in-person): these consist of guest lectures on specific topics linked with the module, but not directly assessed

  • Tutorials (in-person): where students are first given the space to experiment with the calculations/methodologies learned in the module and where, afterwards, the solutions are presented and discussed by the lecturers

  • Captured content: recordings for the in-person lectures

  • Guided learning: based on reading of scientific literature related to the module content, suggested by the lecturer to the students


Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.

Other information

The School of Mechanical Engineering Sciences is committed to developing graduates with strengths in Employability, Digital Capabilities, Global and Cultural Capabilities, Sustainability, and Resourcefulness and Resilience.

This module is designed to allow students to develop knowledge, skills, and capabilities in the following areas:

  • Digital capabilities: the students will use appropriate technology to complete authentic assignments MS Word for report writing, Excel for data presentation such as graph plotting and data handling. They will also be able to use specialist software (Matlab) to solve engineering problems.

  • Sustainability: this pillar is very relevant to this module as innovative electric and hybrid electric powertrains, power losses generation and reduction, and their effect on energy efficiency of vehicles, are directly discussed in details in the module and assessed in the assignments.
