How does steer by wire work? | All-New Lexus RZ 450e

The One Motion Grip steer-by-wire system is one of the most significant new technologies featured in the all-new, all-electric Lexus RZ. There is no mechanical link and no conventional steering column; instead, an electrical connection is used to send inputs from the steering wheel and the wheels. The result is instant response and more precise steering control.

The driver will also notice less steering wheel sway when travelling over rough roads; stable control and correction in strong crosswinds; and excellent straight-line performance on angled surfaces. Steering feel is important for driver confidence and control. Lexus engineers have ensured the system still provides feel and feedback at all times, maintaining a strong connection between driver and car.

The optional One Motion Grip steer-by-wire system comes with a new steering yoke, replacing the traditional steering wheel. The steer-by-wire technology requires less steering effort from the driver: with only a 150-degree turn of the yoke needed to move from straight ahead to left or right lock, there is no need for hand-over-hand turns.

What if the ’electrical’ connection fails?

[WarriorTier]

I still have my Rx330 from 2004, tape player and all. Best car I have ever owned

[batmanatkinson]

"Bro got bluetooth steering wheel" memes coming soon

I'm curious about whatever servos are in the steering wheel to mimic the force feedback that we are used to from mechanical steering. Like how the steering wheel in a traditional setup pulls back to center when you start driving forward after backing out of a parking spot.

Steer by wire is a game changer. Great technology advancement, Lexus.

This looks promising for people with only one hand or an injury of the hand, arm, or shoulder.

[GreatIrreligious]

Bravo Lexus! Finally, you did something worth. Even Tesla didn't do it yet.

[juansanchez-vevu]

thank you for reliable and luxuries cars
GREAT JAPANESE quality

[AjucelvesMulimela]

It's a next level technology. I have expecting this technology for long. It's boring to have to steer more than 360 degrees to make a turn.

[tbr]

So you're going to "heighten the engagement between driver and vehicle" by removing one of the last direct mechanical connections linking the two.

[markp]

Do you guarantee this system will never steer someone into danger either through a mistake with the automatic emergency steering or if it gets hacked.

[CPCARPRO]

My favorite car is Lexus keep it up Ok and when I grow up I will buy one

[gglen]

I tend to think it is a terrible idea, but it is a Toyota and Toyota are very serious about long term reliability. Maybe, the self drive system takes over in the case of a steering signal fault?? Basic self drive could pull the car to a stop without too much drama. It'd suck, but better than a fiery death anyday.

[blackflagqwerty]

Now you can be charged a subscription fee to enable steering!

[gdrain]

At this point a Rear engine Front wheel drive can possibly be made. One step closer.

[skyeurguy]

what if theres a power steeing malfunction and you have no control over the car?

[Byehk]

That's actually a really really useful feature and should be implemented in all future cars

[RC-ldoj]

”Officer, I exited the freeway and when I tried to pull into the parking space the steering wheel turned the car much faster than I anticipated and I crashed into that car/person.”

[Samueljr]

I think it does sound cool as concept. But Its a bad idea. No muscular memory and no direct mechanical linkage between the wheel and steering rack. All brands are triying to avoid all mechanical things, some things should remain mechanic though

[ERICK-diyz]

Yeah but how much will it cost to fix when it breaks? 🤣 I'll stick to conventional steering, hydraulic steering at that.
