About this course

Course Summary

In this first part of Vehicle Dynamics, we illuminate the longitudinal dynamic aspects of vehicles.

Clear and brief: acceleration and braking.

In Detail: After an introduction, we will look at driving resistances and slip, explain the demand of power and limits of a car, then clarify the needs for a clutch and gears and look at the rear and front weights during acceleration and braking. The course will be finished by two applications from automotive mechatronics.

What will I learn?

By the end of the course you will …

  • understand basic principles of accelerating and braking a car.
  • know the driving resistances and their influences on vehicle dynamics.
  • understand the discrepancy between demands and limits of powertrain.
  • understand the necessity of gears and clutch.
  • understand the correlation between braking, wheel load and recovery of energy.
  • be able to calculate simple properties of a car.

What do I have to know?

Some basic understanding of the following subjects will help you successfully participate in this course: Algebra; Trigonometric Functions; Differential Calculus; Linear Algebra; Vectors; Coordinate Systems; Force, Torque, Equilibrium; Mass, Center of Gravity, Moment of Inertia; Method of Sections, Friction, Newton's Law, (Lagrange's Equation)
