What is the course about?
Course Summary
In this second part of Vehicle Dynamics, we will illuminate the lateral dynamic aspects of vehicles.
Clear and brief: the cornering of a car.
In Detail: We will start with a simple single-track model and then describe the slip angle of a wheel. The slip angle results in cornering forces, which are essential for understanding lateral dynamics. After that, we will look at the dependency between longitudinal and lateral forces using Kamm’s circle and Krempel’s diagram. Then we will investigate steady state cornering, stability and the influence of different weight distributions between inner and outer side wheels of the car. The course will finish with two applications from automotive mechatronics.
