Electrical Systems

Illustration: Siemens VDO

The electrical system has become the common denominator in vehicle system design. Many systems that once were mechanically driven are now utilizing electric drive for simplicity and overall efficiency. This increases the demands on vehicle charging systems and wiring and has led engineers to move towards 36/42 volt electrical systems.

More electronic content is being added to vehicles with each new model year. Tighter emissions and safety regulations require more careful monitoring and control of vehicle functions. Computer modules are now controlling most vehicle systems, and these modules often share data over a network.

There is no escaping the fact that automotive technicians need to have a thorough understanding of electrical/electronic theory and have a strong diagnostic background. Learning these skills ought to be the first priority of any automotive technology student.
