Course objective:

Gaining basic knowledge of electrical and electronic systems on motor vehicles.

Course contents:

Electrical system of motor vehicles and its subsystems. Fundamental laws of electrical engineering and their application in the construction and dimensioning of electrical systems. Basic characteristics of passive electronic elements installed in the electrical system of motor vehicles (resistors, condensers, coils, diodes, transistors, thyristors). Sources of electric power on motor vehicles: generators, storage batteries and electric starters. Electric diagrams of joining elements. Fundamentals of electrical measurements and validity checks of certain elements and components of electrical systems, fault detection. Requirements on the system elements depending on the driving conditions (electric load). Ignition subsystem: battery platinum ignition subsystem, electronic ignition systems. Other subsystems: ABS, TCS, ESP, air-conditioning, air bag, system of lights, windscreen washing and wiping system, engine blockage, central locking and other electronic fittings in modern cars. Radio and telecommunication equipment in cars. CAN systems. Vehicle diagnostic systems.


Identification of electrical systems on motor vehicles, basic system elements and their role in proper system functioning. Competence for reading electric diagrams, fault finding and checking the operation of particular elements and the whole system.

Learning outcomes:

Having passed the exam, the student will be able to: 1. Identify electrical and electronic systems in a vehicle. 2. Identify working processes in complex systems of motor vehicles. 3. Use modern methods and devices for determining the technical condition of electrical and electronic systems. 4. Apply appropriate organisational and technical maintenance procedures for electrical and electronic systems. These learning outcomes contribute to the following outcomes of the study programme: - Explain the working principles for the assemblies and devices in motor vehicles. - Apply the technological processes of motor vehicle maintenance. - Recognise the need for lifelong learning and using broader literature in motor vehicle maintenance.
