13. Prerequisites  
14. Description of lectures
Force on the wheel of the vehicle, modern wheel models, static and dynamic geometric characteristics of the wheel from the point of view of road safety. Analyzing the torque and force ratios of the power transmission system, examining its dynamic characteristics. Geometric design of wheel suspension, use of individual suspension elements.
The vibration analysis of the vehicle is the element of the suspension. Dynamic testing of the braking of the vehicle, methods of dividing the braking force per axle, the basic schemes of the braking system, the characteristic use of each element. Dynamic analysis of steering, typical use of individual elements (trapezoidal arm, track bar, steering wheel, steering wheel and shaft, ball joints).
Presentation of software suitable for the development of vehicle dynamics models, longitudinal and transverse vehicle dynamics, tools of regulation. Dynamic analysis and modeling of rollover processes.
The elements of active and passive vehicle safety are: the presentation of vehicle dynamical control systems, systems for mitigating the consequences of accidents, and familiarizing them with their operational characteristics. A detailed description of the sensors and actuators required for the operation of the above systems, the possibilities of using the data stored in these and their control units in the investigation of accidents, during the reconstruction of the vehicle's movement.
15. Description of practices
16. Description of labortory practices
Creating dynamic models using theoretical knowledge, critical analysis of selected vehicle or vehicle unit, subsystem based on traffic safety considerations.

18. Requirements, way to determine a grade (obtain a signature)
During the semester 1 midterm test has to be completed with more the 50 % of the maximal points.
The conditions for obtaining the signature are the completing the midterm test, attending all labs and submitting the homework on accepted level.
Final outcome of the subject is defined by the result of the mid-term exam in 30% proportion, the homework in 20% proportion, and the final exam in 50% proportion. All requirements have to be fulfilled to successfully finish the subject.
19. Opportunity for repeat/retake and delayed completion
The midterm test can be retaken once. The homework can be delivered once additionally. One lab can be done once additionally.
