The course is structured in: - frontal lectures (about 52h), intended to give the students the basic concepts and understanding of electronic systems in vehicles, their operation and performance parameters (as detailed in the program); - numerical exercises (about 8h), in which the concepts and performance parameters introduced in theorical lectures will be applied with reference to simple numerical examples and case studies in the automotive field. In the exercise classes, some practical demonstrations of microprocessor-based systems will be also given.

Exam: Compulsory oral exam;

Oral exam (15-20min), intended to verify the acquisition of the expected learning outcomes (see above). The student will be asked to: - illustrate the structure and the operation principles of electronic systems and sub-systems in a vehicle (especially in terms of block diagrams and/or simplified electrical circuits); - introduce and properly define the main performance parameters of components and sub-systems; - discuss the main criteria and tradeoffs in the design of electric/electronic systems and subsystems with reference to vehicle applications; - discuss electronic systems requirements in simple vehicle applications, also with reference to simple numerical exercises to be solved interactively during the oral test; In the evaluation, the following points are considered: 1) the understanding of the concepts and the ability to explain them; 2) the ability to provide very focused and concise answers to specific questions; 3) the adoption of a correct terminology; 4) the ability to apply/adapt the concepts in simple real-world problems; 5) the awareness of the typical numerical values of electronic systems parameters in automotive applications.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
