Course abstract

The aim of the course is to acquire theoretical and practical skills in determination of automobile exploitation parameters. Estimation methods and experiential determination of dynamic of automobile, braking, steerability and stability parameters practice with up-to-day technology possibilities is usable also for practical operations of engineering specialists.

Learning outcomes and their assessment

1. Knowledge - can do practical calculations according to selected knowledge. Students acquire specific knowledge and their critical understanding in relation with automobile application characteristics, their correlations, methods of determination and analysis. Knows the parameters of car trekking, handling and stability, their application and interconnection - test of theory 1.
2. Skills - can apply practically methods of determination of automobile dynamics, braking, stability, steering, traction and consumption of fuel as well as analyse the experimentally obtained results. Can skillfully use different calculation methods for selection and comparison of power vehicles. To be able to experimentally determine the parameters of aotomobile hiking and stability and related calculations - laboratory works.

3. Competence - can evaluate and analyse the automobile exploitation characteristics and select automobiles most suitable to the exploitation conditions that can be substantiated by calculations. Able to perform car performance parameters calculations - homework, task test 1.
