Aim

In this course the focus is put on the understanding of the coupled planar dynamics of road vehicles during steering and braking (or driving) including various non-linear effects from tires, suspension etcetera.

Learning outcomes (after completion of the course the student should be able to)

  • Identify and discuss factors (e.g. load transfer) that cause interactions between the different vehicle subsystems, e.g. braking and steering. 
  • Develop and implement computer models of vehicle dynamics behavior and critically analyze results from numerical simulations. 
  • Identify and mathematically characterize linear and nonlinear tire behavior and the influence of this behavior on vehicle performance using Handling Diagram. 
  • Identify suspension and tire characteristics influencing vehicle chassis performance and stability in both low and high-speed manoeuvres, under both steady-state and transient manoeuvres, with the ability to mathematically justify how changes in vehicle parameters (e.g. mass or weight distribution) can be stabilizing or destabilizing. 
  • Understand how to extend the mathematical analysis of the passenger car to heavy vehicles. 
  • Understand and characterize the change in vehicle performance and vehicle/roadway interaction due to automated subsystems such as e.g. ABS, ESC and Rear Wheel Steering. 
  • Construct specifications for vehicle control systems.
The course contributes to the United Nations sustainable development goals regarding Sustainable cities and communities samhällenssss(SDG 13) and Climate action (SDG 11) in the sense that vehicle dynamics and control are important aspects both for vehicle safety and energy efficiency.

Content

The mathematics and mechanics concepts and notations used in the course are reviewed. The tire and vehicle models suitable for analysing the coupled dynamics during steering and braking or driving are developed and then used to evaluate handling performance in various manoeuvres. Some aspects about vehicle stability and the principles, basic implementation and specifications for automated vehicle control systems are included. At the end the challenges posed by heavy vehicles are discussed but not covered in detail.
