• Semester 2, position 2

Aims of this course include achieving of competences for conquering the basic specific knowledge and skills needed for overviewing and understanding of problems of motor vehicles, their functioning, basic systems, as well as vehicle`s drag and dynamic characteristics in particular environment conditions.

After successful completition of this course, students should be trained to: - Recognize basic categories and characteristics of vehicles; - Review and analyze the characteristics of vehicle systems and components; - Explain vehicle design concept and analyze existing concepts; - Define and explain forces acting on a vehicle in motion; - Describe force distribution in tyre–surface contact; - Identify characteristic parameters needed to determine adhesion, sliding and rolling resistance; - Recognize modern vehicle electronic systems and to assess their influence on traffic safety.

Theoretical part of course consist of the following units: Introduction: Basic terms, vehicle classification and categorization, vehicle homologation; Concepts of vehicle design, basic systems and elements; Transmission system: construction, tasks and way of functioning – clutch, gearbox, drive axle, final drive, wheels; Suspension and steering system, braking system, support structure; Vehicle propulsion: forces in wheel – surface contact, adhesion coefficient, slip coefficient, determination of reactive forces, power transfer from engine to wheels; Passenger and freight vehicles: maximum performances, power balance, acceleration and braking, vehicle stability; Vehicle safety: safety parameters, electronic systems on vehicle.

Review of basic vehicle classification and categorization; basics of vehicle design concepts; engine; Transmission system – clutch, gearbox, driving axle (review of characteristic examples); Basic vehicle systems – wheels, suspension and steering, braking (review of characteristic examples); View of characteristic examples on specific schemes and on real models.

No special requirements.
