Course detail
Driving Mechanisms
FSI-QHL Acad. year: 2024/2025 Winter semester
The course introduces students to the basic concepts and arrangement of drive systems of passenger and commercial vehicles with both conventional, hybrid and electric drives. Computational models of powertrains are a basic tool for finding optimal concepts and parameters of modern powertrains. In addition to the engine itself, students are also introduced to the key functional units of the drive chain for transmitting torque to the drive wheels. Teaching in exercises with computer support is complemented by practical examples of the relevant parts of the driveline.

Entry knowledge
Knowledge of mathematics taught at the bachelor's level and including linear algebra (matrices, determinants, systems of linear equations, etc.), differential and integral calculus, and ordinary differential equations. Knowledge of the basics of kinematics, dynamics, flexibility and strength.
Rules for evaluation and completion of the course
Credit is conditional on active participation in exercises. The exam verifies knowledge acquired in lectures and exercises, is written including a test in e-learning and may have an oral part verifying knowledge after the written part.
Aims
The aim of the course is to provide students with basic knowledge about the conceptual design and calculations of the power unit and other parts of the drive chain. The subject should help students to understand the connections related to the construction, load, vibration and noise of parts of the drive train, which they can subsequently apply in other specialized subjects, and especially in practice.
