Subject fundamentals
Acquisition of a system-level view of electrical and electronic systems in vehicles, including a good understanding of the main techniques for acquiring and transmitting information in a vehicle. Knowledge of related reliability, diagnostics and regulation issues.
Expected learning outcomes
Understanding of the operation of the main electric (alternator, accumulator, wiring harness, starter motor) and electronic (electronic control units (ECUs), sensors, actuators) systems in a vehicle. Ability to describe the main electric and electronic components for vehicles in terms of system-level parameters and/or performance benchmarks. Definition of the electrical specifications of components/subsystems employed in vehicle applications. Knowledge of the targets and of the operation of the main electronic systems in a car considering different requirements and regulation issues (pollutant emissions, active and passive safety, performance, reliability).
Understanding of data acquisition techniques and packet-based networks.
Knowledge of wired networks (CANbus, LINbus, FlexRay, Ethernet) and their application in vehicles.
Prerequisites / Assumed knowledge
A sound understanding of the topics in circuit theory (steady-state analysis of linear electric circuits with constant and sine-wave excitations, transient analysis) and basic electronics (transistors, opamps).
Contents
Electric systems in a vehicle: alternator, rectifier, accumulator, starter motor, car-level energy balance. Emerging technologies. Reliability issues.

Assessment and grading criteria
Oral exam. The student will be asked to:
- illustrate the structure and the operation principles of electric and electronic systems and sub-systems in a vehicle (especially in terms of block diagrams and simplified electrical circuits);
- introduce the main performance parameters and/or characteristic curves of components and sub-systems having an idea of their order of magnitude in vehicle applications;
- discuss the main criteria to be considered in the design of different electric/electronic systems and subsystems with reference to real-world vehicle applications.
