Steer-by-wire

Just saw this on BBC:

Basic idea - no mechanical link between steering wheel and car wheels - instead some electronics instread.

From the article:

In addition it suggested that the development would "insulate" motorists from disturbances caused by unnecessary feedback.
"For example, even on a road surface with minor ridges or furrows, the driver no longer has to grip the steering wheel tightly and make detailed adjustments, so travelling on the intended path becomes easier," it said in a statement.

Your thoughts people ?


Mine: -> ugh!!!! I like feeling the road and getting feedback. I don't want my car to feel like an arcade game. Yes there are advantages to it (see the article) but to my mind they don't outweigh the disadvantages!

On the plus side it would make converting cars from LHD->RHD very easy.

Yeah they say one of the advantages is you can put the wheel wherever you want.

Perhaps it will just be one of those Wii steering wheels for Wii Mariokart :pac:

BMW have had this for a while with adaptive steering being an option on the Flame (chris Bangle designed) 7,5 series.

Lock to lock went from 1.5turns while stopped/inching along to 7 turns at motorway speed

If it's not a boeing im not going

There's still a mechanical connection in the BMW, with variable assistance/ratios. You could get a punto with variable assistance, although it does sound like there's extra smarts going on in terms of stability control in the BMW system.

Steer by wire is a totally different prospect, NO mechanical connection, and a bit daunting considering the amount of body control module etc issues in modern cars.

Meh.... Saab had this in the early 90s on a concept 9000

Scary or maybe I'm picking it up wrong but in the article they say that the driver wont feel feedback from the road, for example, a ridge on the side of the road where the wheel normally pulls to one side. Surely this is needed for you to know when to correct your line of driving?!?

Ehhh .. how are you supposed to steer the car if there is no power ?

Does it mean they could design inherently unstable cars that're more efficient/corner faster, and use the steering controller to make it not spin out?

I would think the fact that you are headed for a ditch or another car would tell you to correct your line of driving :P

Horrible idea. Drivers are 'insulated' from the environment enough as it is in modern cars, it also makes them very boring to drive

I agree that a large part of driving is the 'feel' from the wheels through the steering wheel. But steer by wire could be done in such a way that the forces, vibrations and 'feel' of the road can still be transmitted back to the driver.

The only problem I see is a mechanical backup system would be needed if the software proves to be less than 100% reliable.

BMW designed a system for disabled drivers like Philippe Streiff's. He steers with a handle left and right, accelerate and brakes by moving the handle front or back, and changes gear with the other hand.

I wonder whether it's a steer by wire system ?

Sorrry - the video is in French ... I couldn't find an equivalent in English

As per the video, there are about 100 people using this system in France.

Think force feedback guys

People said all the same things when they started putting power steering in cars.(and electric windows and cruise control etc etc)

True about the backup, at least in an airbus you can use the engines.

Fly by wire makes a lot of sense in huge aeroplanes that a human couldn't fly or else planes like f 22 raptors, that couldn't be flown without it.

Driving a car doesn't require such a huge mechanical advantage or the countless instant reactions that those do.

And what they said about power steering was true. I still prefer non power steering cars. Power steering feels a bit like playing a computer game

The hand brake should always be a manual device in my book, pretty much anything that can stop a car should.

My understanding is that every motorised vehicle capable of over 50 km/h must have a direct mechanical link, hence the article saying there is such a backup.

I have driven tractors for years that have only a hydraulic link. The driving experience isn't great.

Hey don't knock tractors......I've jumped one before......not entirely by design :pac:
