Course detail
Dynamics of Vehicles
FSI-QDY Acad. year: 2024/2025 Winter semester
The course will acquaint with the basic theoretical findings, oriented to vehicle dynamic. The core of the subject is to understand relations between applied forces and vehicle motion. On the basis of this knowledge will be possible to get understanding of the function of vehicle systems, and to create relations between vehicle design and dynamic characteristics. The course gets theoretical background for consequential courses in specialization motor vehicles.

Assesment methods and criteria linked to learning outcomes
Requirements for Course-unit credit award: The orientation within problems discussed and the ability of solving them, examined by working-out assigned tasks without significant mistakes. Continuous study checking is carried out together with given tasks verification. Examination: The exam verifies and evaluates the knowledge of physical fundamentals of presented problems, theirs mathematical description on a presented level and application to solved tasks. The exam consists of a written part (test) and an oral part. Final evaluation consists of: 1. Evaluation of the work on seminars (elaborated tasks). 2. Result of the writing part of the exam (test). 3. Result of the oral part of the exam.
Attendance at seminars is obligatory, checked by a teacher. The way of compensation of absence is solved individually with a course provider.

Aims
The aim is to get theoretical findings, which enable to the students to analyze vehicle dynamics behavior and to understand the function of mechanical and electronical vehicle systems.
The students will get theoretical and terminological knowledge in the area of vehicle dynamics. The principles are directly applicable in consequential courses of motor vehicles specialization.
