How Electric Power Steering Work

[@steviestarr9987]

This is a absolute professional presentation, quick, to the point, didn't have to watch 20 minutes of someone taking stuff apart. I'm going to prescribe. Thanks for your time.

[@speedkar99]

Thanks I'm glad you appreciate the video style

[@jdmking4776]

What are you prescribing though?

[@baldy555]

Subscribe you mean

[@MadHatter764]

Yep, his videos are fast paced and edit out the fights with fasteners...quick jump cuts over the slow parts. I also like the sound quality and really love the lack of wheezing, grunting, heavy breathing and loud clunks in his videos.

[@natecaine7473]

Super useful and very thorough (start to finish tour thru the system). Only suggestion is that some of the details on the video are lost due to constantly moving the parts around. Could be improved by setting the object down while you discuss and point out the features. (Especially true on the electronics). Clearly this is the best video I've seen on the EPS system.

[@pieterjlansbergen6988]

[@Vuratzkee]

Wow! You are the real deal mechanic, knows every single detail of parts, it’s function, and how it works. What a knowledge. 👍

[@Greatdome99]

Worm gear, not spiral gear. You can back-drive a worm-and-gear set if the ratio is small--it has nothing to do with gear material. Anything over about 4:1 the gearset will lock when back-driven.

[@ctsfiddler]

From the radio knob to the power steering computer, it's just amazing all these parts are made for each car and where they're made and how the whole process began and then start again with a new model year, it's just amazing. this guy is amazing also.

[@speedkar99]

Agreed. So many parts in a car and amazing if you try to understand how they work

[@piedcrowmechatronix5350]

Simple, straight to the point...you say exactly what we want to hear... keep it up.

[@johnbarker419]

Yes, that's correct, people are using columns from a variety of cars as self-contained units for hot rodding. Not every column works this way, but a lot of them have a failsafe mode which works pretty well but doesn't have the function of varying steering assist based on road speed. These can operate without other inputs. Others have also built control boxes which allow you to change the level of steering assist with the twist of a potentiometer.

[@CarputingYT]

Hell yeah! It's becoming more common for people to swap these Prius electric power steering systems onto hotrods, great video and topic, speedkar99! Thanks for the way you present, you're absolutely awesome, have a great day!

This must be one of the most intelligent technical KZbin channels in existence. My old Mercedes A-Klasse had electric power steering and I have wondered for years how it worked. Now I know...or at least have a rudimentary knowledge to the extent that I could understand all that was said. Thanks for this amazingly professional presentation!

[@Visionery1]

Excellent explanation! Electric power steering over-complicates a very simple age-old hydraulic process.

[@speedkar99]

Thanks

[@detonater1348]

But electric power steering is easier to replace and costs cheaper

[@MattExzy]

Actually looks simpler to me.. hydraulic systems deal with 1000+ psi worth of fluid pressure, cooling, lines that could leak, pump complexity... although this uses a brushed motor, I imagine the low duty cycle/low speed operation means it should last a while.

[@JayDee-xj9lu]

@@MattExzy I think it was all made because they wanted the fuel economy to be better. Power steering pump create drag most of the time.

I loved it...if only more 'how to'/'DIY' channels would be as direct and not afraid to use your 'brothers' tools to disassemble the parts the way the rest of us do that would make my world go around a little bit faster...it was 'clear and concise' where as everyone else seems to want time to drag on to make their videos longer for reasons unknown to me... I greatly appreciate your approach...Keep up the good work. I was looking for the breakdown of the torque sensors and even though that was at the end the prelude to that part was full of good footage at a speed that didnt loose my attention...I'm not easily impressed and that video was impressive enough for me to comment...you're welcome, thank you...

[@jcjko5504]

this is not a English class.

[@MarekReinsch]

Thanks for the great video! Now I understand better why my racing friends are removing electric power steering - it has some slack and now I know where! Plus that friction on the motor gears. There are quite a few EPS systems used on resto-mods like this Toyota one or one from Opel (more popular swap in Europe). I personally did use Nissan one on my DeLorean build as I know the engineer responsible for it at Nissan. Newer EPS systems actually use signals from Angle Sensor but that is mostly for ADAS purposes (line correction etc). Another important stuff is that some EPS systems need vehicle speed signals to adjust power steering support. The older column will look for PWM signal, but newer for CAN frames from ABS (Wheel Speed Sensor). Thanks again! Long-time listener!

[@speedkar99]

Thanks! The "slop" in the torsion beam is the same if you have hydraulic steering

[@ChuckThree]

Omfg YES! Please compare the systems that use Electric Hydraulic Pumps like Volvo, Porsche GT3 Cup, etc Drifters struggle finding a system that provides enough self steer and immediate feedback. Perhaps one design is inherently better for high rpm, low cooling potential.

[@speedkar99]

No power steering is the best for feedback lol

Great video. Good luck putting it all back together 😧

[@juandelacruz3799]

Awesome video. Direct to the point.

[@JonPrevost]

Incorrect. That tiny shaft IS TAKING all the torque of the input from the driver. What you're pointing out is the "backup plan" for when the torque sensing fails, you can then still transmit large forces through the steering column to steer the vehicle. Redundant systems are made this way so we don't just fail. Think Dad with his hands hovering around his baby just learning how to walk. Not necessary, but millimeters from disaster. Glad Dad was there :) I can explain the torque sensor better but I think it's not needed. It's pretty cool, is had differential for maximized signal strength. Love this engineering and your disassembly videos.

[@wi8shad0w]

[@paulerickson1906]

So it is an electrical power assist for the steering. The older systems which used hydraulic power steering were direct connected also. They used the hydraulic pressure from the power steering pump to help turn the wheels. Very interesting.

[@ColonelLucario]

I have a Toyota Yaris from 2002 with an electrical steering assist The issue is that when I’m on lower gear (1, 2) I have trouble to do little steering but when I’m on higher gear (3 and above) with higher speeds it’s really easy to steer the wheels The thing is that when I must do turns, or for parking I must really use a lot of force to steer the wheels and it’s really annoying I really don’t know if it’s a normal behavior or not…

[@danko6582]

Steering wheel directly coupled to shaft. Microprocessor references torque sensor to drive a DC motor that adds torque via worm drive. Worm drive has a metal worm and plastic helical gear that allows it to be back driven in case power steering fails.

[@michaelmolter8828]

I didn’t know that worm gears (at least this kind) can be back driven by the spur gear. I had thought they were always self locking. Cool!

[@Mcfreddo]

What a huge amount of work to design, manufacture, + that magnets are costly-using precious metals, for a miserable fuel saving. Just use the old, cheap and reliable fluid power steering pump, like the old days?

[@alro2434]

THANKS, well done! Especially surprised that the worm gear can be driven! IIRC that's the way the Torsen LSD's work, the worm can drive but not be driven, that and most window openers, houses and cars.

Around 6:18 when you toss the airbag with the metal side facing up I just about fell over! All the manuals say to put the metal side down so that if the airbag accidentally deploys for some reason that you don't launch the metal, to wherever it's going to go.

Great video my friend ( and I’m a mechanic ). Great suggestion to use that column on a custom build.

[@Xeno8086]

Eps is intricate in a different way compared to hydraulic. Is there any advantage for mounting the eps motor to the column instead of rack? The only reason I can think of is that the column mounted motor would be less exposed to external elements like dust / humidity / water.

[@pcnepal]

Seems like you nailed it!

[@speedkar99]

Column is for smaller vehicles. Larger ones use rack mount

[@ovalwingnut]

I love the info-tainment but stay for your Brother's Toothbrush. I was also surprised to see how easy it was to rotate the electric motor's worm gear via' the beveled (large) gear.. Of course it needs to be able to be turned. It must have a interesting tooth engagement. Usually it's quite hard to turn a gear set backwards aka in reverse, yes? I'm not sure if I've explained that correctly but then again, I don't have a toothbrush to aid me :O) Cheers from So, CA. 3rd House On the Right. You RoCk1
