Course Objectives

At the end of this course, students will

  • have a basic understanding of the components and configurations of powertrains for conventional and hybrid electric vehicles.
  • be familiar with the performance of internal combustion engine and electric motor treated as a black-box and of the use of analytical functions in approximating experimentally obtained engine and motor characteristics.
  • be able to express resistances to the motion of road vehicles analytically, and will have a sound idea of the data required as well as how these data can be obtained.
  • be able to relate the engine characteristics, power train specifications, and the interaction between the tires and road surface for generation of tractive effort.
  • be able to predict the performance of a specified road vehicle analytically, with the maximum speed, acceleration, gradeability, and fuel consumption being the performance measures.
  • be able to predict the stopping distance of a road vehicle and select an appropriate brake force distribution factor to satisfy the requirements of international standards.
  • be able to estimate the fuel consumption of a road vehicle at constant speed and for a driving cycle.
  • have an insight into the process of the determination of a set of preliminary reduction ratios for the gearbox and differential of a road vehicle.

What this course is not:

  • Powertrain modelling or control class.
  • Design of drivetrain elements or subsystems.
