Course abstract

The aim of the course is to acquire knowledge about the structure, operation of electrical equipment of mobile equipment, used electricity sources, voltages, currents and control signals. The study course introduced the structure of electronic control units, components and functions to be performed, control algorithms are introduced. Improved knowledge of electronic circuit elements, microcontrollers, measuring transducers, actuators and electric motors in mobile technology. Electronic control systems for internal combustion engines, transmissions, PTOs, suspensions, brakes, traction and stability are also covered.

Learning outcomes and their assessment

1. Knowledge - knows the construction and operation of mobile electrical equipment, the latest technical solutions. The acquired knowledge serves as a basis for further practical activities and research - test, independent work.
2. Skills - able to creatively use the knowledge of mobile technology in the evaluation of electrical equipment performance, perform experimental research, calculations and analysis. Can explain and substantiate the operating mode of mobile electrical equipment. Able to perform experimental methodology of electrical equipment tests, process and analyze the results obtained in experiments - test, independent work.

3. Competence - the Master's student is able to independently determine and analyze the causes of operation and refusal of mobile electrical equipment, justify decision-making decisions, use other areas and study courses to acquire knowledge - test, independent work.
