How Electric Power Steering Works

Here's a detailed look inside the electric power steering (EPS) system in your car and how it works!
In this video, an EPS rack and pinion is cut apart to show how each individual component works. The steering column takes input from the driver at the steering wheel and inputs it to the torque sensor. The torque sensor, sends a signal out to the EPS computer to power up the electric motor using MOSFETs, based on the amount of assist required. The pinion gear turns the rack, with the electric motor rotating about the rack via a recirculating ball system, providing assist.
The vehicle in this video is a 2005 Honda Accord Hybrid.
