How Electric Power Steering Works
Автокөліктер мен көлік құралдары
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.

with these EPS we've got an extra source of CAN Bus errors. The EPS module has a learned "centering function" to help the vehicle drive straight else car is unstable around neutral.

Rapid fire details. I love it. Everything I ever learned about how things work has come from taking things apart. The best way to learn.
This explanation is really good, but think of how talented the people were that designed that steering and made it work flawlessly. Kudos to them and their ingenuity.

Bravo ! Very well done. I thought I had seen enough steering box's to last a life time. I was wrong.
Thanks a lot for bringing that science to us ! Was wondering since a lot of time how the torque could be measured ^^
I'm kind of a tinkerer. There are multiple projects I've wanted to make that have been beyond my price range due to the cost of parts. Yesterday it occurred to me to see if I could use parts from junked cars. You helped me see it's totally possible. Thank you!
My 2020 RAV4 has this electric assist. I really like it! So smooth, center's real well, no pump, hoses, fluid and valves in the rack. Oh ya, no pump whine at full turn lock! Thank you for this video!

Thanks for taking time to dissect the system for everyone. Looking at the substantial motor armature I see why this system tends to damp rack movement. Good for passenger cars and trucks.
Great video! Always wondered how these worked.
Thanks for this. Love videos like this and learning. Finally started investing a bunch of tools to start. Next goal is to invest in some space
Just got my first vehicle with electric power steering and I like it so far. The steering feel is really good and so quiet.
Great video explanation. Answers a lot of questions. The real trick is putting that thing back together. Thanks!

Would love to see a mechanical review of a 09-12 rav4 v6/awd model. This is great content, keep it up.
This reminds me of citroen's hydraulic diravi steering. There was no physical linkage too, a kind of physical backup linkage would apply only in the case the hydraulic system would fail. It was very comfortable for the time it has been built but it was very soft and did give allmost no feedback from wheels to steering wheel.

Pretty cool. The *stator* is the field frame, and in this case has permanent magnets. It is a six pole machine. The armature (where power conversion takes place) is the part that rotates, in this case.
