Electrical & Electronic Systems

Overview

Electrical and electronic systems provide power, control, and communication across modern vehicles. They support everything from basic starting and charging functions to advanced control and monitoring systems.

This page introduces how electrical and electronic systems are structured and links to explanations of key components and functions.

What This System Does

Electrical and electronic systems are responsible for:

​

  • Supplying electrical power to vehicle systems

  • Monitoring operating conditions through sensors

  • Controlling components using electronic modules

  • Communicating information across the vehicle

 

As vehicles have evolved, these systems have become increasingly integrated.

How the System Is Structured

Most vehicles use a layered structure:

​

  1. Power generation and storage
    Electrical energy is generated and stored for use.

  2. Distribution and protection
    Power is routed safely to different systems.

  3. Sensing and control
    Sensors provide information used by control modules.

  4. Actuation and communication
    Electrical signals trigger physical actions and share data.

 

The complexity of this structure depends on vehicle type and level of electronic control.

  • Actuators explained

Electronic Control

How systems are coordinated electronically.

  • Control modules explained

  • Vehicle communication basics

Common Points of Confusion

Electrical and electronic systems are often grouped together, but they serve different roles. Electrical systems primarily supply power, while electronic systems use that power to control and coordinate vehicle functions.

Understanding this distinction helps clarify how modern vehicles operate.
