Course detail

Motor Vehicles

FSI-QMV Acad. year: 2020/2021 Winter semester

Subject motor vehicles focuses on problems of construction, testing, driving charecteristic and modern motor vehicles and trailers operation. Private cars, trucks, buses, semi-trailers and trailers. This subject is about structural solution of basic parts of modern motor vehicles e.g. axles and their suspension and damping, brake systems including electronic systems (ABS, ESP, HBA,... ), steering mechanisms, incorporation of engine aggregate into a car including its operating mechanism. Following will be a talk about active and pasive safety of vehicles including the most modern asistent systems in vehicles.

Learning outcomes of the course unit

Graduates of this subject will obtain complete rewiew of basic connections for motor vehicles construction including illustrations of specific technical solutions of both private cars and trucks of the most modern style. Furthemore, graduates will get an idea about possibilities component and complex automobile testing.

Prerequisites

kinematics basics, dynamics basics, strength of materials basics, machine parts design and mechanisms, vehicle dynamics

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.

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.

Aims

The target of this subject is to acquaint the graduates with fundamental part of modern technology of vehicles construction in connection with the user and technology of production.

Specification of controlled education, way of implementation and compensation for absences

Attendance at seminars is obligatory, checked by a teacher. The way of compensation of absence is solved individually with a course provider.
