It's a steering wheel. Musk thought it was made by Tesla and installed on "the best car in the world" model s playd, named yoke. Yoke was born in June 2021. Because yoke has a touch button, father Ma abandoned his eldest brother's gear lever , cancelled his second brother's light control lever , and lost his third brother's wiper lever .
When you drive this model s play with yoke, the forward gear will be swiped forward on the touch screen, and the backward gear will be swiped back on the touch screen. All the lights on the left and right of the light wiper are operated by touch buttons.
It's full of science fiction
Father Ma himself is very optimistic about yoke.
Musk: "I've been using yoke for a while and it's really awesome. A more awesome progressive steering system requires complex mechanical transmission design or pure wire control, and we'll realize this more awesome thing in a few years."
Spiritual shareholders also think it's good that yoke and iPhone Removing the headphone jack is an epoch-making progress.
But many people still don't like York.
In conclusion, yoke is a mostly bad comment**
What a coincidence.
Lexus also built the same steering wheel as Yorke and created a one motion grip technology, which is called OMG for the time being.
This will be used in the pure electric SUV rz450e that will be launched next year.
Unlike most of yokes' bad reviews, OMG is highly praised by people who have tested the car.
After the test drive of CNET, a well-known magazine, published an article saying that "the steering wheel of Lexus is strange, but it is also a little good".
Last year, when Tesla yoke was born, CNET said that " yoke is a security risk ".
why？ Why? Everyone is a special-shaped yoke steering wheel. I Tesla yoke is a potential safety hazard, and Lexus OMG is interesting.
This matter caused a lot of heated discussion in the promotion, many people angrily sprayed the double standard of CNET, much like the mobile phone circle sprayed DxOMark recharge evaluation in those years.
But y1s1, this time, no wonder CNET.
Judging from the current data, whether from the technology itself or public acceptance, OMG is much better than Tesla yoke**
Why do you say that? Let's start with the car turning.
The principle of car steering is the following dynamic diagram.
I believe the poor friends who touch the car less always have a question, I turned the steering wheel 540 ° for one and a half turns, but the wheel only turned dozens of degrees , why?
Because this thing called steering ratio refers to the ratio of steering wheel steering angle to wheel steering angle, which is realized by the steering gear in the above dynamic diagram.
For example, if you turn the steering wheel 60 ° to the left and the wheel 30 ° to the left, the steering ratio is 2:1.
Generally, the steering ratio of affordable cars we drive is mostly constant 15:1 (different types of cars may be different).
But slowly, the speed of the car is getting faster and faster. A group of people find that when driving at high speed, such as 200km / h or even 300km / h, the steering wheel moves slightly, the wheel is easy to make a big turn, and the car may lose stability and throw out.
Therefore, this group of people want to make a variable steering ratio
To put it bluntly, when driving at low speed, reversing into the warehouse or parking on the side, I make the steering ratio smaller, the steering wheel doesn't need to be full, or even one and a half times, and the wheels can turn at a large angle.
When driving at high speed, make the speed ratio higher at two or three hundred kilometers. Even if the steering wheel is turned at a slightly larger angle, the wheels only turn a little, improve the high-speed driving stability of the car**
F1 cars and flagship models of some high-end brands will use variable steering ratio technology.
When this thing is made, it's easy to say it's easy for a thief, but difficult to say it's difficult for a thief**
For example, the vGr variable gear ratio system launched by Honda in 1997 actually makes the gear rack dense in the middle and sparse on both sides.
In the middle, large steering ratio is suitable for high-speed lane changing, and small steering ratio on both sides is suitable for parking and reversing.
Ordinary cars will use this simple vGr variable steering ratio technology.
For example, Audi made 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 RS, is also very Q8. Sports and comfort go hand in hand. The dynamic all wheel steering technology scores half of the credit.
RS Q8 achieved a lap speed of 1:42.326 in Zhejiang international circuit, breaking the lap speed record of mass-produced SUV**
I won't say the principle. It's too complicated. I really want to know. It's suggested to leave a message for her to do at station B.
However, the above are all mechanical structures to realize variable steering ratio. BMW originally developed a set of electronic variable steering ratio system . On the E60 generation 5 series, the steering ratio can be switched between 5.0-1.7 according to the real-time vehicle speed.
To sum up, with variable steering ratio technology, the steering wheel can be designed as a special-shaped
This is also the reason why York is mostly bad, because many car owners reported that although it is a special-shaped yoke steering wheel, it is almost a fixed steering ratio . You still have to turn one and a half 540 ° on one side to hit the steering wheel and kill the wheel.
How do the old drivers rub the rectangular steering wheel for the same turn and a half?
Moreover, it's silly to adjust forward and backward gears on the touch screen. It's OK to change the dial with the hand wave or even the knob, but when you change gears on the touch screen, when the car is stuck, people are stupid**
The OMG of Lexus rz450e is a pure steer by wire with variable steering ratio. The wheel can be killed when the steering wheel rotates only about 150 degrees**
And omg people didn't lose all the "big brother, two brothers and three brothers" like York. There are still some buttons and a lot of paddles.
However, yoke has been used in mass production vehicles, but the rz450e will be mass produced next year. It's not certain whether it will be like this for a long time. It's hard to say whether policies and regulations allow by wire steering.
After all, at the end of last year, we officially began to formulate national standards for phase controlled steering**
Moreover, I estimate that even if the standard of steering by wire is issued, it can be loaded and mass produced in the future, and there must be spare mechanical transmission devices.
Just like the widely used brake by wire, there must be mechanical parking and braking systems, not only by wire.
The braking system and steering system, which are body subsystems closely related to driving safety, are all handled by the "computer". If they die, they will be in trouble**
But steering by wire is a trend. There is no doubt that steering by wire means better cooperation with automatic driving. For those concept cars you see now, if they can retract the steering wheel, the first step is to turn the traditional mechanical transmission steering system into wire steering system.
So we have to turn to this step by wire, but please**
Car companies should not cancel the steering paddle, wiper paddle and buttons. Just like OMG, leave some mechanical beauty for the car with mechanical structure.
I'll start with a bolt Q here. Thank you, car companies.
