Ford's Bringing Adaptive Steering To the Masses
cartechboy writes: "Most automakers have made the jump from hydraulic power steering to electronic power steering to help conserve fuel. By using an electric motor instead of a hydraulic system, less energy is drawn from the engine. Many luxury automakers have also introduced adaptive steering with the electronic power steering systems, but now Ford is looking to bring this feature to the masses. Adaptive steering builds on the existing speed-sensitive function of the electronic power steering system by altering the steering ratio and effort based on driver inputs and settings. The system uses a precision-controlled actuator placed inside the steering wheel. It's an electric motor and gearing system that can essentially add or subtract from the driver's steering inputs. This will make the vehicle easier to maneuver at low speeds, and make a vehicle feel more stable at high speeds. The system (video) will be offered on certain Ford vehicles within the next 12 months."
Does that mean that if one of those actuators or logic board malfunctions, that it could steer a car into traffic? All it takes is for a few milliseconds and some force to jerk the wheel out of someone's hands. Or so I would imagine.
Life is not for the lazy.
So I guess this isn't good news, is it?
That large wheel that can allow two hands grip it completely to steer the car is very old fashioned. For the current crop of young drivers just coming in, they will learn it so much faster if we replace the steering wheels with this. They have already accumulated thousands of hours of experience long before they hit driver-ed class. This electric steering will help us get there faster.
sed -e 's/Chuck Norris/Rajnikant/g' joke > fact
So tell me please, which company is the innovator?
This tech is why you get to take your Ford Escape in for a recall today. Enjoy!
Boy I can't wait to try out the Version 1.0 of this bad boy.
No thanks, I'll keep my hand on the burger and cell phone and coffee and makeup and... where I'm in full control
This isn't exactly new. While I don't know how exactly the system works, Honda offered variable gear steering on the S2000 Type V 14 years ago. A while I don't know if any "for the masses" cars has variable gear steering, there are a number of manufacturers who currently offer it. (BMW, for example.)
I can see this getting ugly quickly.
I want to delete my account but Slashdot doesn't allow it.
They just recalled their last attempt at changing the steering.
EPAS is already recalled and it just came out in the newer cars.
Now while that attempt (easier) was recalled, they now have their sights set even higher (harder) yet they couldn't seem to get the first one right.
Perhaps they should slow down and clear out all the recalls before trying to innovate again. Building upon a bad foundation just leads to more cruft in the way of fixing the foundation.
It's a system that most European car makers switched to years ago.
Sounds idiotic to me. Non-linear steering is great, but any sort of dynamic/adaptive steering that changes according to conditions is stupid beyond belief and will cause an endless stream of accidents because the driver can no longer predict how the car will react to similar steering motions.

I like my car as is. 16 years old and still going strong. And of course not an American car. You'd have to be insane to buy an American car. American made = junk.
My 1993 Lincoln Mark VIII had this type of steering system. Not exactly new tech.
Ford recall affects Ford Escape and Mercury models from 2008 through 2011 model years and some 2011-2013 Ford Explorer models. The Ford recall was made due to issues with electric power steering systems.

Really Ford?
I have a ford with adaptive steering... You can barely tell its there. The basic goal is to give you lots of help while the car is stationary or moving slow... but make it harder to jerk the wheel when doing 80. Back in the 80s they way over did power steering so you had basically no road feel at all and if someone even bumped the wheel while you were on the freeway it could send you into a spin or cause you to roll. So they cut back on the amount of "help" power steering provided.
But my truck was recalled yesterday because faults in the system could cause power steering to fail and lead to an accident. They've had 7 confirmed accidents due to this out of some 800,000 vehicles sold.
Ironic this story pops up a day after a recall for the very feature being advertised. lol
I'll be excited about this when a company besides Ford does it. Yeah, I admit it; I am biased. I put aside said bias and bought a used Taurus once. It's transmission promptly died on me.
This system was first introduced by Honda in the their JDM S2000. It was later copied by BMW as their "Active Steering" system and offered in USA in 5-series and 3-series cars. Note that such systems effectively break the solid link between the steering wheel and the steering rack. There were a number of reports of Active Steering failures in 3-series BMW E9x cars. BMW abandoned the system for in new 3-series, replacing of with ordinary electric booster without ratio-changing ability.
Despite the fact that such systems break the sold mechanical link between the steering wheel and the steering rack, they are normally rather well protected from mechanical failures. At least Honda's and BMW's systems will normally "fuse" steering shaft in case of any mechanical component disintegration, restoring the classic solid steering link. However, such systems are very susceptible to software failures and simple electrical failures (like water getting into electronics), when the systems "gets a mind of its own" and begins to steer the car overriding driver's input. There is an epic thread on e90post (now sanitized) about consequences of such failure in a E92 car http://www.e90post.com/forums/...
As a car guy, I prefer hydraulic power steering. Electric implementations so far leave you too isolated from the road (both input and output, or feedback are important when handling car). It is also unclear how these new systems will age or if they will fail gracefully.
They are behind the times. This was done about 20 years ago and was called "Driver assisted stearing".
I absolutely hated it. I got use to apply a specific amount of preasure on a wheel as I went around a mountain road, then the car decided to add or subtract to that required preasure, and as a result I either over corrected or under corrected. Damn near got into a couple of wrecks.
Very old news.
I'm not sure about the US, but Euro and Asian car makers have been using similar electric power steering systems (assisted by a motor in the steering column or steering rack) since the early 2000's.
Also... Electric power steering systems are NOT fly by wire. A physical link still remains between the steering wheel and wheels. The EPS system could loose power or malfunction and you would still be able to steer ok.
(I've just retrofitted EPS from a 2006 Toyota RAV4 into a 1990 Toyota Celica)
Yeah, and since when does a car have auto-aim? You call that realistic driving? Any driver with a keyboard and mouse would beat the crap a console joystick driver!
I8-D
Huh, I just bought a 2014 Kia Soul this weekend with this very feature. Ford is a day late and a dollar (or $5000) short.
Does anyone sell a real car anymore, and not a rolling computer? If not, sounds like there is a market ripe for the picking.

Where is Ford going to save the five dollars THIS time?
Anybody remember the original Pinto, also remembered as a molotov cocktail if struck from the rear? Ford was warned by their engineers that in such collisions, some of the drivers would end up burned alive. Cost to fix: $5 per vehicle. Ford chose the cheaper alternative of paying off lawsuits, without making a serious dent in the Pinto's bottom line.
So I ask again, where will they save money to kill their customers THIS time?

What if it malfunctions and actively fights against you?
Excellent. We'll remove any physical effort required to drive a car, and the entire country will gain weight as a result. Now we have a huge market for exercise machines.
Well, there are plenty of kit cars you can buy that are quite primitive, but they seem to cost much more than a conventional mass produced car.

Read IEC 61508 and ISO 26262
The standard documents can be purchased from whatever organization is responsible for standardization in you country.
They cover all the "What if contrived example" that you will find people posting on Slashdot.
... about ten years after every small car in Europe. Again. Well done Ford!
Sure, you could build something 100% from scratch and even skip the 'kits', or just buy an older car that was pre-perversion in age, but i was thinking along the lines of a current day mass produced vehicle.
I have not seen one, but that didn't mean it does not exist.
---- Booth was a patriot ----
They also had people shooting at them...
In theory but not in practice. One of the earliest, if not the first widely deployed fly-by-wire, was the F-16. The number of F-16s lost to enemy action was very small compared to those lost due to mechanical/electronics malfunction.
Yes ejection seats predate fly-by-wire but they certainly made fly-by-wire early adoption a lot easier.
I like my car interfaces the same way I like my computer interfaces: just do exactly what the fuck I tell it to.
It's on my ten year old Prius, what next? Electric air con compressor? Oops, got that too...
There was an unknown error in the submission.
Ford is making it cheaper, not innovating. Just sayin....
The Honda CRZ's steering changes depending on the drive mode selection. In sport mode it gets tighter for better handling, in normal and econ it has a soft feel to it.
*It's not what you can do for the Dark Side but what the Dark Side can do for you!*
Bringing adaptive steering to the masses... Does it mean we'll soon see loads of people doing splits between cars while they are driving backward?
my 2014 Mazda CX-5 has this standard.
