Adaptive steering (variable ratio steering) has been available in some cars without SbW for over a decade now. So it's not a game changer in that respect. Perhaps it is for people who do not know how to operate the wheel in a motor vehicle properly during parking maneuvers, but can I perhaps suggest another, much simpler and cheaper, game-changer for them? Just educate yourselves! Get some driving lessons and learn to drive a car. What are you doing with a driver's license when you don't even know how to operate the wheel properly?

I have the ability, with the Tesla FSD trial, to get out of the car and remotely move it into a tight space. The future is bright.

@@briansilver9652 well, it still isn't parking it perfectly in the middel of a parking spot thus not really very promising for Europe

@@RamonSmits The software is the worse it will ever be, constant improvement.

@@briansilver9652 sure, just not usable for Europe. Same as parking next to the curb. In Europe you really need to park tight against the curb. That is something auto park can't do at all with FSD V12

@@smarticus6384 Like what? There is nothing SbW adds to the currently already available steering options for automobile drivers.

looking at this between 2002-15~ era and my modified crap they don't need the racks as all 4 wheels can become independent ( maximum */angel is 70*-90* so turns can become shopping cart good and or pro-drift-mode etc ) controled with current version/technology, and alignments by wire and or on the fly, something i liked for my auto-X and or daily driver but i gave up on the idea as a teenager-30yo because i couldn't see anyways of getting it road legal, as big-foot ( monster truck's and hydraulic-only, but same challenges for wire/ electric control's ) changed the USA 🇺🇸 law's ( mechanical-only, assisted is gray area of law ) and by chance made it illegal for everyone

Lamborghini has active camber and toe adjustments coming to market. For maximum performance a touch of toe out will dramatically improve turn in feel. Unstable alignment configurations are advantageous, but they need to be brief.

You've presumably heard of the kind of faults where the ECU craps itself and everything in the car dies while rolling down the road. Now imagine this scenario in a steer by wire and brake by wire vehicle. I definitely won't be anywhere near the front of the queue for any car with this setup until it's been very well proven in a few million cars. Since ZF is a well regarded company that have been doing decent engineering for a long time, they'll have considered this, but that doesn't mean other players in the car market won't be playing fast and loose with customer safety if steer by wire gets normalised.

If a tree falls down in the 80s but nobody harvests it, does it still make a noise. No. The failed experiments don't mean much. Nobody remembers the Palm Pilot. Everyone remembers the iPhone.

@@dirkbester9050 Not failed experiments so much as a feature customers weren't willing to pay for in anything that wasn't a very high profit margin premium car, which continues to this day - just about every manufacturer has steer by wire on the rear axle of their 4 wheel steered vehicles, so adding one more axle steered by wire isn't a massive leap anymore. If anything that situation has got significantly worse thanks to all the inflation of the cost of living that hasn't been matched by income increases since the 80s.

It's the same company. ZF is a large supplier to many car brands and they produce a lot more subsystems and parts than just gearboxes.

Much simpler to cut the floor out of a car where the material you need to remove is just the floor than to do the same in a car where that space is full of high voltage battery. Also, making custom tiedowns in a normal car or van floor is stupidly easy, because you just have a sheet of structural steel to bolt into, because again there's no battery under the floor. I'm pretty sure the people who modify vehicles for wheelchairs are avoiding electric ones like the plague because a completely new set of techniques are likely to be needed. There is one absolutely epic reason to go with an electric car for mobility and that's that it can very quickly charge the wheelchair as you drive to where you're going.

Ford will have to buy it. They are already struggling to get costs down to where a sale does not cost them money.

@@markplott4820 yet the lightning truck is a better OVERALL ev family truck than the cybertruck and it wasnt even designed from the groundup , it won without even trying super hard.

The F-150 Lightning rear suspension uses semi-trailing arms, which are not suited to steering. The multi-link rear suspensions used by other battery-electric trucks are more expensive, but more easily accommodate rear steering. Steering a beam axle (such as the rear of the gas F-150 and most other pickups) carries a substantial cost and complexity penalty.

@@brianb-p6586 - the Lightning is still using OUTDATED horse & buggy TECH in 2024......lol.

@@davidmkandhla ZF solved all of this before Elon decided to build a "truck" without curves.

It's not that difficult. 4WS has been around for decades, and front steer-by-wire was first put into production by Toyota, not Tesla.

@@brianb-p6586umm... Yeah. But we are actually understand why this video published? ZF want to show that CT is not uniqe and they can do the same. CT is not pathfinder, but it did what tesla did with e-cars, highlited posibilty.

ZF makes the front electric steering system for the Cybertruck.

Вас закроют в машине, и будут везти куда им нужно. Они точно люди?

Yep. Why did they move them closer?

I believe they tilted them away from the body to prevent scuffing the paint and put them right back on the markers afterwards when possible however the tires were often on top of the base plates at those times so they could not really move anything back into place until the tire was no longer making contact holding the base plate to the pavement. Best!

I don’t think they were moving the pilons closer. They moved one a tiney bit to the outside when Sandy was parking with RWS off (to avoid damage).

It's just a few inches. I mean the benefit of the system is pretty clear.

No, they didn’t. Give us timestamps, but while you’re doing that, I think you’ll notice they did not move them and if they did, you couldn’t tell from the video.

Japanese manufacturers were putting steer by wire in the odd car over a decade ago. It's not even slightly new as a technology, the main problem is it's solving a problem most people don't have in a more expensive way, so negligible consumer interest - I already have electrically assisted power steering with mechanical feedback straight from the road with far fewer parts, safe steering in the event of power loss, and way less computer intervention. The most interesting thing the electronics related to the steering do in my car is feed the steering angle and wheel speed to the satnav, so it can still tell me where I am in tunnels using dead reckoning, and that's in a satnav system that first came out around 20 years ago. 48V electrics, on the other hand, should have probably have happened 20 years ago - that was the point where I first read about the car industry pushing for it. There still is no good argument against it apart from 48 V is lisghtly more prone to giving people shocks that can kill them, but in a 400+ V electric car that seems somewhat moot. The Mercedes S Class from the late 90's/early 2000s was supposedly running enough electrical toys that they claimed it could at least theoretically pull 5 horsepower from the battery. Converting to less medieval units, that's about 3.7 kW, which would require a 310 Amp current to deliver it at 12 Volts. I highly doubt that figure ever occurred in the real world, but the cold cranking amperage on some batteries is in that territory, so there would be enough copper going from the battery to deliver that much power for a short time.

ZF has offered their system to anyone who wants it for a long time. The 4WS systems are commonly used in expensive cars, but no one has chosen to use front steer-by-wire from ZF yet... all of which has nothing to do with either Munro or Tesla.

ZF has been a world leader in steering gear for a long time - this is just a normal part of their product offerings, not a replacement for transmission business.

@@brianb-p6586 The transmission business, at least as it stands right now, won’t be around for too much longer. EVs don’t need highly complex eight (or more) speed transmissions- just a single speed reduction gear. I think anyone with half a brain at ZF knows this, and I’ll bet they’re scrambling to look at alternatives.

I'm not.😢

Steer by wire (fly by wire) has been used on commercial and military aircraft since the 80's without major issues. There's an element of redundancy that needs to be built in.

When Kyle Conner was doing his range tests of the Cybertruck, and ran the battery until the vehicle shut down on the side of the road, I was wondering if they also lost steering ability, or if there was a hidden safety buffer built in, which was not disclosed by Tesla. They never said if the steering went dead or not.

​@@eddiegardner8232steering runs off LV. If HV goes down the LV will keep safety critical systems up for a short while.

​@@eddiegardner8232also, there is a buffer. They don't disclose because it's not a rigid setting. It can vary based on a number of conditions.

Unlikely. Cars today have umpteen computer boxes all doing this & that and communicating. Take one away and the whole system falls over.

@@davidelliott5843 So install it with all the modules? I don't see any reason It wouldn't work. Also systems don't just fall over unless you throw a rod, there are redundancies for a reason.

ZF literally make these systems for car manufacturers to buy. You can probably buy it straight from them, but integrating it into a car that wasn't designed for it won't be cheap or easy - easier than converting a steer by wire vehicle to mechanical steering though 😛.

@@peglor A challenge always makes it more fun :P

But the future is already here! It’s called Cybertruck

Way too many people have experienced their car trying to veer off the road or into oncoming traffic for no reason thanks to lane assist malfunctioning for any sane person to think that severing the link completely and giving the car's systems primary control is a good idea.

Toyota = YAWN 🥱

That's rear wheel steering

You're missing the point.

@@jamesengland7461 amazing how people will miss the point like that. its just to showcase how effective 4 wheel steering is.

Yes! Plus it doesn't cost me a premium to have 4-wheel steer.

Thanks for the info , never knew

Low sales, price was dropped from $7,700, to 5k, 2k,1k and then discontinued. Honda tried 4ws with the Prelude in the same period with similar disinterest from most buyers.

$5k is the early 00s is like $15k today. It also wasn't very reliable

Going to full steer by wire made this far easier. Quadrasteer was too complex.

Alfa Romeo had a passive rear steer system but any wear in the bushes and joints just messed it up.

at best gm Quadrstear worked, but it was UNRELIABLE.

Lol so true. I've spent years in multiple asian countries, and this is largely a non-issue everywhere but the US

@t850 Here in Europe we do not to park "nose first" and it's much easier and faster 👍👍

@@deltajohnny I live in Europe too. My personal tactic regardig the parking is as follows: If the parking spot is on the left side of the street then I park nose first If on the right, then back first. In Europe streets are generally much more narrow that in the US and we and still manage to park cars sideways if neccesary. In US parking it's a logistics problem if you don't park "nose first"...xD

​@@t850 Yes, some americans would have a hard time driving and parking in oir narrow streets and parkings 😅😅😉😉

The steering wasn’t developed for parking, even if it didn’t make parking easier they still would move forward with the technology. Making parking easier is just a advantage.

Mechanical and steer by wire steering racks are basically the same. Replacement costs should be similar. The power steering motors will at least double the replacement costs. However the car has two which can work independently but usually share the load. They should be more durable over time than the heavy 12v steering systems we have in today’s ICE cars.

Cybertruck , has fewer parts , is more than 90% reliable ALL THE TIME.

@@davidelliott5843 Let's hope. Only time shall tell.

@@markplott4820 I, for one am not impressed by the idea of 90% reliable steering.

Perhaps you’d like a Model T?

I was also offered by Alfa Romeo in the 1990s. The snag is any wear in suspension joints really messes it up.

Every modern rear suspension exhibits passive rear steering to some extent.

Sandy would benefit from an advanced driving course!

Well, as I understand, the CT has 2 computers on different power circuits, each cross connected to 2 motors on different circuits, plus dual sensor systems on the steering input end. .

No reason. 'By wire' simplifies a plane... but not a car.

Because it enables new features and functionality. It's not a single incremental change, but an entire variety of changes it enables. Whether we should never aspire to change (particularly improvement through change) is up for debate - there is certainly value in basic systems that anyone can wrench on - i think there will always be that go-kart aspect of vehicle/tool ownership. Variable gain steering, adjustable steering, remote steering... our interfaces with vehicles has been pretty basic and required us to hack additions onto in order to innovate, such as with existing auto-steer. The concerns make sense - but imagine where we'd be if airplanes still had to be steered via cables and pulleys.

I've had the power steering booster pump fail on one car, and an engine fire caused by a p/s hose chafing on the exhaust manifold of another. So as much as it makes life easier, I'd even score two marks against conventional power steering systems. All these new electronics only add new failure modes. And having more of them, they multiply the chances of a failure. Like computerized transmissions where "the computer" fails and the only way to fix it is to swap out a $2500 circuit board.

@@lyfandeth this is true of every advance in automotive technology. Gotta embrace change or be left behind. The world won't stay one way forever. Especially in something so engrianed In our day to day life.

The 48 volt electrical system has its own battery.

In an airplane there is generally much more time to react to an electrical failure. They have multiple power backups. Each engine has a generator, there is often a APU and if all that fails they pop a prop driven generator out to create power. I have heard that the CT has 2 redundant power systems. Don't know enough about it to say more.

@@davidelliott5843 Yes, but is there one or two 48 volt batteries? If one fails and there is only one and it fails... You're screwed!

@@danharold3087 Thanks. Yes, I've also heard that they have redundant systems, but unless that actually includes two batteries so it is fully redundant, there is a problem. Hopefully someone with direct knowledge of these systems will let us know.

@@DavidJohnson-tv2nn Exactly. How about using one set of wheels in the regen mode during a power failure to power the system! Some say the tech is too expensive for redundant power backup. It is already there. Maybe more transistors.

All manufacturers need to implement it now anyways, so much better

The MCAS system is an example of management corruption and maybe communication failure rather than engineering. Phantom breaking on the Tesla is most likely the car being cautious. We could expand the period of allowed uncertainty prior to applying the emergency stop but it would be unwise. Better to improve the system so as to reduce the periods of uncertainty.

This is not what concerns me. What concerns me more is things like memory corruption from software bugs and random cosmic rays, intermittent electrical issues after years of salt accelerated corrosion, and other bizarre failures that are hard to predict and give no warning of trouble

Electronics are the most durable part of any car. However any safety intervention such as emergency steering should be as reliable as emergency braking. There are so many edge cases of what’s already an edge case it’s hard to know how that could work.

HW4 vehicles , have no issues w/ Phantom Breaking.

@@markplott4820 That’s nice to know since I just bought one, an Austin-made Dual Motor.

It adds up a lot of wait time in contrast to a first time right. Especially in peak and tight parking spaces it saves you from anxiety and time

You would need a Hyundai for that :-) kzfaq.info/get/bejne/l8xjdJyGs660pXU.html&ab_channel=TorqueNews

The ridiculously oversized wheels in SUV's already eat so much into the interior space with the current poor steering lock that many massive SUV's have no more interior space than a decent wagon/estate/touring/kombi bodied car from the 2000s. But then again they've made it so bad already that making it worse may not affect their sales, since so many of them spend their entire lives carrying one person anyway 😞. Also, driving wheels that can turn 90 degrees from straight is very difficult by conventional means, but hub motors are a thing in electric vehicles, so that could be worked around.

Technical difficulties so we were forced to use the iPhone audio for Neb.

@MunroLive Great solution, and we could hear it reasonably well 👏👏

There is at minimum a Lexus with Steer-by-Wire in production. Engineering Explained has a vidoe comparing the systems.

Sandy just showed the cybertuck steering system, a lot of the components show ZF's logo meaning CT's steer by wire was codeveloped with ZF.

@@Alhussainba yes, I saw that. Still makes for a very weird video.

I think its a price... 😂

What does it say? By the way I have Heard that cyber truck uses zf System

so whats wrong? because i'm clearly not smart enough to see it. There has been zero accident related to fly-by-wire in the aviation industry in the past 50 years. All systems require a double-triple physical redundancy with a triple-quadruple computer control redundancy with a physical hydraulic backup. There is literally no other kind of movement control system in any industry beside the rocket industry that has such a high level of redundancy.

@@simson4t if so, the would shurely talk about it.

Indeed was wondering the same.

Have you expand 1 report to reports? Have we seen verification. The one report then nothing. Not belittling this.

Who do you think developed the steer by wire system in the Cybertruck?

Steering a driven beam axle suspension is complex, heavy, and expensive... and commercial vehicles don't want any of those, so 4WS is out for most of them. Heavy vehicles built with massive budgets (fire apparatus, some military vehicles) has independent rear suspension and even available 4WS (using Oshkosh TAK-4 suspension, for instance).

It's even faster than a human. Just like how predictive braking applies more brake pressure than the driver immediately commands to dramatically reduce stopping distance. The same is done for drive by wire within the stability limits of the vehicle.

@@otm646 that would be strange if it would oversteer. So far all steer bij wire videos I've seen on KZfaq suffer from lag/latency and turn speed

The Ethernet gigabit data system is so fast there is effectively no latency.

@@RamonSmits There is no lag with the CT. If anything, the complaint is that the steering rack ratio is too fast. No other truck on the market can go lock to lock faster, be that with a conventionally hydraulic system or an EPS system.

@@davidelliott5843 even ancient analog electronics or digital systems of 40 years ago would still have negligible latency for steering purposes.

Also about break by wire, acselerator by wire, gear by wire etc... 80% of road accidents because of it... Or not?

Suggestion? Never fly.

Apparently, the Luddite movement is alive and well.

​@@rmkep Do you remember when car mirrors and headlight replacements were economical? I understand @harriettanthony7352 reaction. Lets see what they put in the $25K cars everyone is/was working on.

One could argue that better vehicle control will save lives too. I don't want to debate it as there is too much I don't know. They just mention improved crush w/o the steering column.

Crush which absorbs energy requires vehicle length. That shorter the car the less the crush. What we need is lighter large vehicles. The Tesla cars are a good example. The passenger compartment is a high strength hot stamped boron steel cage and the rest of the car absorbs the energy. Tesla makes each side of the passenger compartment as a single piece hot stamped part. Maybe the closest thing to a roll cage in every car.
