When you drive this Model S Plaid with yoke, swipe forward on the touch screen for forward gear, and swipe backward on the touch screen for reverse gear. The lights, wipers, left and right lights are all operated with touch buttons.
Looking around, it looks like science fiction.
Daddy Ma himself is very optimistic about yoke.
Musk: “I’ve been using yoke for a while, it’s really awesome. Better progressive steering systems require complex mechanical transmission designs or pure wire controls, and we’ll implement this more awesomeness in a few years. toy”.
Spiritual shareholders also feel good, thinking that yoke andiPhoneThe removal of the headphone jack is an epoch-making progress.
But many people still don’t like yoke.
In conclusion, yoke is aMostly bad reviews.
Lexus also made a steering wheel like the yoke, and came up with a One Motion Grip technology, let’s call it OMG.
As shown below, it will be used in the pure electric SUV RZ450e that will be launched next year.
Unlike yoke’s mostly negative reviews, OMG is in the mouths of those who have tested it,Unanimously praised.
The well-known magazine CNET published an article after the test drive, saying “this Lexus steering wheel is strange, but also kind of good”.
And last year, when the Tesla Yoke was born, CNET said “Yoke is a security hazard“.
why? Why? Everyone is an alien yoke steering wheel, my Tesla yoke is a safety hazard, a Lexus OMG is just fun.
This matter caused a lot of heated discussion on Twitter.Many people anger CNET double standard,Great yearscell phoneCircle the posture of DXOMARK recharge evaluation.
But y1s1, no wonder CNET this time.
Judging from the current data, whether in terms of technology itself or public acceptance,OMG is far better than Tesla yoke.
Why do you say that? Let’s start with the car turning.
The principle of car steering is the following animation.
I believe that the poor friends who touch the car have always had a question,I turned the steering wheel 540° a half turn, but the wheels only turned a few dozen degrees., why is this?
Because this thing called steering ratio refers to the ratio of the steering angle of the steering wheel to the steering angle of the wheels, which is achieved by the steering machine in the animation above.
For example, if you turn the steering wheel 60° to the left and the wheels turn 30° to the left, the steering ratio is 2:1.
Generally we drive a cheap car, the steering ratio is mostly constant 15:1 (different types of cars may be different).
But slowly, the speed of the car is getting faster and faster, and there are groups of people who find that when driving at high speed, such as 200km/h or even 300km/h, if the steering wheel is slightly moved, the wheels can easily make a big turn, and the car may become unstable and thrown out.
So, this group of people wanted to have a variable steering ratio.
To put it bluntly, when driving at a low speed when reversing into the garage or parking on the side, I make the steering ratio smaller, the steering wheel does not need to be full, or even a half-turn, and the wheels can be turned at a large angle.
When driving at high speed, when two or three hundred kilometers, let the speed ratio become higher, even if the steering wheel is turned a little larger, the wheels will only turn a little,Improve the high-speed driving stability of the car.
Variable steering ratio technology is used in F1 cars and some flagship models of high-end brands.
Build this thing,It’s easy to say it’s easy, and it’s hard to say it’s hard.
For example, the VGR variable gear ratio system introduced by Honda in 1997 actually made the rack and pinion denser in the middle and sparser on both sides.
In the middle, the large steering ratio is suitable for high-speed lane changes, and the small steering ratio on both sides is suitable for parking and reversing.
A normal car will use this simple VGR variable steering ratio technology.
It’s a little harder, like Audi does.Dynamic Steering Technology, a wave generator, a 100-tooth flexible gear, a 102-tooth stator gear, and a 100-tooth driven gear.
Audi’s RS Q8, although it is an RS, is also very Q8. Sport and comfort go hand in hand, and the dynamic all-wheel steering technology in it gets half the credit.
RS Q8 laps 1:42.326 at Zhejiang International Circuit, set a new lap record for a mass-produced SUV.
Let’s not talk about the principle, it’s too complicated, I really want to know the suggestion to go to station B and leave a message for her to do it.
But all of the above are still mechanical structures to achieve variable steering ratio. BMW originally made a setElectronic Variable Steering Ratio System, On the 5 Series of the E60 generation, the steering ratio can be switched between 5.0-1.7 according to the real-time vehicle speed.
To sum up, with the variable steering ratio technology, the steering wheel can be designed into a special shape.
This is also the reason why yoke has mostly bad reviews, because many car owners have reported that although it is a special-shaped yoke steering wheel,but almost a fixed steering ratio. You still have to turn one and a half 540 degrees on one side to fully turn the steering wheel and kill the wheels.
The same circle and a half, how does this rectangular steering wheel make old drivers rub?
Also, adjusting forward and reverse gears on the touchscreen is silly. It’s okay to change the paddles with the hand wave, or even change the knobs, but changing gears on the touch screen,When a car gets stuck, people are stupid?
And the OMG of Lexus RZ450e is pure wire-controlled steering, variable steering ratio,Just turn the steering wheel about 150 degrees and the wheels can be killed.
And OMG people didn’t get rid of the “big brother, second brother and third brother” like Yoke did. There are still buttons that should be there, and there are a lot of levers that should be.
But then again, Yoke has already been used in mass production cars, but RZ450e will not be mass-produced until next year. It is uncertain whether it will be like this, and it is hard to say whether policies and regulations allow wire-controlled steering.
After all, at the end of last year,We have only officially begun to formulate national standards for phase-controlled steering.
And I estimate that even if the wire-controlled steering standard is introduced, it can be installed in mass production in the future, and there must be a spare mechanical transmission.
Just like the commonly used wire-controlled brakes, there must be a mechanical parking and braking system, not just wire-controlled.
The braking system and steering system, which are closely related to driving safety, are the body subsystems.All are handed over to the “computer” for processing, and it will be troublesome if the machine crashes.
But there is no doubt that wire-controlled steering is a trend, and wire-controlled steering means that it can better cooperate with automatic driving. The concept cars you see now can put the steering wheel in. The first step is to turn the traditional mechanical transmission steering system into a wire-controlled steering system.
Therefore, this step must be taken when turning the wire control.But begging.
Car companies, don’t cancel the steering lever, wiper lever, buttons, etc., like OMG, just leave some mechanical aesthetics for the mechanical structure of the car.
I’ll put a Q first here, thank you car companies.
