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.
@@speedkar99 thanks for cutting it to pieces so l don't have to. I can see a lot of different uses for this setup other than steering a car that will come in very handy.
@@speedkar99 To me the quirky part is the twist you seem to always add referance to some relatives clothing item and also specilty tools = angle grinder. Very nice fun addition!
thank you for creating educational content that’s very approachable and beginner-friendly, while also not feeling condescending. as a car enthusiast who is in no way a mechanic; i appreciate you.
You are amongst the very best few automotive video producers on You Tube. My guess is you have an engineering background as well as being a mechanic. I am grateful for the time you put into these educational videos.
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.
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!
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!
I'm working in the automotive industry, especially in the EPS electronics R&D field. The way you opened the PCB at 9:25 simply brought tears to my eyes 😂😂😂😂😂
hi.. pls help me.. my car has a electric power steering.. i start my car in a morning my steering wheel is very tight. in two or three minutes its going back to normal.. what is the reason..??
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.
speedkar99 what’s going on that ye car must be scrapped -crash damage ? The components are top quality- Seems recycling components isn’t a thing where you are
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.
great breakdown. those ball drive has me thinking would make great cnc drive.. can only get this info when someone does these breakdowns. thumbs up! and great little jokes.
Your explanations are still pretty good and if you really wanted to, you could send the logic board for the steering controller to Big Clive but he may or may not want to reverse engineer it.
Been subbed since the Toyota/Lexus programming videos. Thanks for the great content, always something new to learn. This looks like a well-made unit also.
Thanks. I kinda drifted away from the how to videos as the how stuff works videos and mechanical reviews have caught on and become more interesting since there isn't too much like that out there.
so, in theory, you could manipulate the torque sensor readings to automate steering without input from the steering wheel. Hope the security on that module is tight...
@@speedkar99 so how likely is moisture or failing component to cause these things to make a sharp left turn when you're at highway speeds? can a human overpower this thing, or is it going to be in control if something goes wrong?
@@lukerediger8431 Note the "fail safe relay" that can disconnect the motor if things go wrong. The ECU likely has two computers that run in lockstep, and if there is a failure it will disengage. And I suppose the two coils in the sensor, are checked against each other as well. I wonder how they would detect a stuck sensor - maybe that joest doesn't happen. Same with that mtor catching on something. I suppose that is the reason for the security screws: don't mess with it.
@@pizzablender yeah.... this bothers the hell out of me, when simple electronics fail due to moisture, tin whiskers etc, they normally just fail to work, but every once in a while they turn up one function to 11... and the idea that my steering might just get snapped full right or left by something with mechanical advantage over me at some random point in the future... If the signal from the sensor shows an increasing voltage as the steering column increases torque, then it should fail safe in that the sensor will always read 0 torque meaning the motor will not be energized, but if moisture gets into the box in the cabin, all bets are off, the H bridge could lock on one way or the other, the collectors on transistors could short to a live wire, and if the ECU is talking to this thing and giving it trim adjustments, a short in the wiring harness could do the same thing. This is before tampering is considered. Auto manufactures are doing stupid shit like letting the Bluetooth module for the entertainment center talk to the ECU, and malicious hacking is increasing. A hydraulic system can't fail like that.
Wow the only think I can see that I don't like for longevity is that plastic torque sensor. Looks like issues wafting to happen on high mileage cars. Thanks for another great video..
Just want to give props: straight, to the point, without any long winded diatribe on the history or power steering or how Yakumi Honda married his wife.......great job! (I hate guys that drone on and on about superfluous crap lol)
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.
Sheesh, everything from a full mechanical disassembly to a complete view of the underlying electronics. Thanks again for a great video!
Thanks. Gotta understand the whole system to appreciate how it works

I love this guy because he puts work into his explanations.
Also his nonchalant jokes about his brothers hat or toothbrush.
Very underrated
Thanks, glad you appreciate my style

I got to get me one of those special bits too. ;)
"So I'm going to use my special security bit to take these off..." *Angle grinder fires up*
Yep, that's my special bit!
@@speedkar99 I knew it was coming but I still laughed like a hyena anyways
Just wanted to drop a thank you. You give the absolute best expalination of how systems work, with a great addition of humor and quirkiness!
Glad you appreciate my work. Why quirky though?
@@speedkar99 To me the quirky part is the twist you seem to always add referance to some relatives clothing item and also specilty tools = angle grinder. Very nice fun addition!
This guy is amazing! Also, I've started using a toothbrush to point to everything while I teach. It's been very effective.
Thanks. Sure it's a good habit
thank you for creating educational content that’s very approachable and beginner-friendly, while also not feeling condescending. as a car enthusiast who is in no way a mechanic; i appreciate you.
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.
I feel like I've been to college on EPS in 10 minutes. Thanks!
#3. Cut off wheel is such a wonderful tool.
You are amongst the very best few automotive video producers on You Tube.
My guess is you have an engineering background as well as being a mechanic.

Sure
And now I put it back together..........great video, great explanations.
that special security tool!!! Soooo SATISFYING!!!
Gotta love my grinder
Nice teardown of an electric steering rack. Thanks

It sure is mechanically simplier and more reliable. But it devoids it of steering feel

Hello, can you tell me what would be ideal EPS gear for electric vehicle ? Is it ball screw or worm gear?
You are a very good teacher straight talking and no if and but could listen to you all day thanks
Superbly ordered and comprehensive
Honda and Mazda do great Electric Power Steering, so much feedback for EPS.
It has to do with their suspension and tire tuning
Yep own a first gen mazda 3 can't tell the difference between that and mechanical sometimes lol
Bravo ! Very well done. I thought I had seen enough steering box's to last a life time. I was wrong.
You seriously deserve more subscribers, great job as always
Bravo! Excellent video! Now I understand why my new OEM steering rack & pinion was so expensive...😫
Thanks! Yep they sure cost alot
great video buddy
im getting a job because of your teaching realy apreciate the help
Wow, what kind of job? Glad I could help
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
Dude, Love how you went into the electronics of it. Cheers.
I love the toothbrush! 😂Excellent job!!! You are very smart AND a clear teacher!
I wish all tech. videos were as clear and fast and accurate as yours is. Well done.
Thanks
😂😂😂 I love that power snap ring tool! Looking forward to every video that you put up my man!💯👍
Thanks a lot for bringing that science to us !
Was wondering since a lot of time how the torque could be measured ^^
phenominal teaching. very grateful to you. regards.
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.
I like your security bits.
I couldn't get by with these security bits on a BMW engine I'm working on
My BS degree EE didn't cover many of these issues. Many Thanks. Bob
This isn't EE ...
Jeeze. You've got so many specialty tools.
I just love your complete set of obscure removal tools; great video
Love the grinder too
Great video explanation. Answers a lot of questions. The real trick is putting that thing back together. Thanks!
I subscribed your channel when u hold the grinder. Absolutely technology is beautiful from inside
Thanks for your exalent video! Wish I had your video's 60 years ago? Keep it up!
Definitely no electric steering racks 60 years ago! But yeah every aspiring mechanic should be able to see these videos
Great video. Full of info and concise. Loved the parts with the fancy special tools. Now waiting for the reassembling tutorial ;-)
No thanks
You did a great job explaining this. Thanks
That was a great explanation of the EPS system! Thanks. Unfortunately I just keep seeing one heck of a linear actuator. :)
Thanks!
Another good video you show us how things work in our car, thank you.
You are welcome
You deserve more subscribers 👏
Hopefully someday. Share with your network
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 detailed description! This guy is really good!
Thanks and glad you learned something new
Very thorough job sir. You covered it all.
Thanks
WELL DONE SIR , YOU MADE IT EVEN A CHILD CAN UNDERSTAND... GOOD JOB ...
It’s such a shame destroying the latest technology comparatively.At least you documented it !
🤘🇬🇧
Destroying what would have been crushed as a scrap car?? I'm doing a favor here...

This still had the physical linkage....
Electromechanical genius! Loved the explanation of the torque sensing system.
That was awesome, I love how you dismantled every part, great video! 👍

He's got the same tools as I have in my tool box. Hammer and grinder!
The best ever

Very educational, thank you.
You welcome
Keep up the good job mate!
Your brother's clothes though 🤣 🤣 always cracking me up!
Haha

Seems like that Honda rack was pretty well built. You had to saw that sh!t apart.
It sure was. In fact most of the racks I've taken apart we're pretty sealed up, see my previous videos.
Thank you for an informative and well presented run down.

5:50 Even he’s just as amazed as we are 😲
Great video as always!
Love that special security bit @ 5:45=))
So complete guy thank you
You are welcome
I learn again! Great job as usual. Thanks for sharing. 👉👊
Thanks I'm glad it was easy to understand
Just found your channel. Informative and entertaining.
Thanks for subscribing
Thank you very much, now I know how it works and how to dissemble it, could you please make another video on reassemble?
🤣
Great explanation. Thank you mister !
You are welcome
Great video! Always wondered how these worked.
Very good information thank you.
Very informative.
Next time you show how to put it all back together.
Not with my special security tools...
Best video in this topic - THANKS!
You are welcome
I always enjoy the remarks about the wife's toothbrush or the brother's T-shirt, but I had a good laugh this time around about the security screw bit.
Hey it's all using what I can!
so, in theory, you could manipulate the torque sensor readings to automate steering without input from the steering wheel. Hope the security on that module is tight...
That's how line keeping assist, automatic parking etc works :)
Yes of course it's hackable

Hello sir, were still waiting for our Core rack.
I scrapped it
very good explanation, mechanical and electronics side. very satisfied. keep up the good job.
