Electric Power-Assisted Steering Systems

Electric Power-Assisted Steering (Part 1)

There are three types of EPAS systems: column-mount; electric hydraulic; and electric rack and pinion.

Historically, steering systems in vehicles were hydraulic.

They utilized a pump and moved the fluid to the power assist: either a steering gear or a rack and pinion. This pump was driven by the engine, usually via a belt. This was only an assist, and the driver was moving the wheels.

Today, the driver still has control of the vehicle, but the assist is coming from an electrical source.
