International Lecture on
Vehicle Dynamics
The goal of this course is to provide you with the tools to calculate and predict the
performance of a car or truck in accelerating/braking, ride, and handling/rollover. In the process
you will come to understand the basic mechanisms and engineering principles that determine the
performance of a motor vehicle, as well as develop familiarity with the terminology.
Overall, the course will help you understand the motor vehicle as a system. The design of a car or
truck always involves a conflict of goals. The suspension system that is optimized for ride, is not
always the best for handling. The powertrain that gives best acceleration is not likely to be the
most fuel efficient. By understanding the primary mechanisms for all modes of performance, you
can better appreciate how to optimize the overall vehicle, because it allows you to:
1. Predict performance of a given design early in the design process,
2. Identify the conflicts in designing for optimal performance in different modes,
3. Set directions for design changes that will improve performance of a given mode. The course will be beneficial to anyone interested in automotive performance. You should find them useful if you are:
A professional engineer with technical interest in vehicle performance
An engineer involved in the design and development of automotive vehicles
A technologist working to achieve a high level of vehicle performance
A manager responsible for vehicle design, development and testing
An engineer who needs to understand the vehicle as a system
A professor involved in teaching, thesis or projects related to vehicle dynamics
An engineering student wishing to participating in BAJA / SUPRA
The course provides a broad overview of vehicle performance described in terms that can be
understood by the lay-person but including engineering analyses and formulas that can allow
even the lay-person to calculate useful performance metrics.
