Tesla Model S Steering Wheel Will Work Using Steer By Wire

By Henry Farkas

By now, all the Tesla fans who frequent this site have seen the pictures of the steering yoke on the refreshed Model S. It’s similar in shape to the steering yokes on airplanes. Of course, nobody thinks that the refreshed Model S can fly so there’s no indication that pushing forward on the Model S yoke will make the nose of the Tesla point downward or that pulling back on the yoke will make the nose of the Tesla point upward. That sort of thing is strictly for airplanes.

Tesla Model S Yoke Steering Wheel

There’s a reason that steering wheels on cars are round, or nearly round. That reason is that in tight spaces, you sometimes need to turn the wheel more than 180 degrees in order to make the front wheels get all the way to the left or to the right. This is a leftover from when cars sometimes came without power steering. For those of you old enough to remember that long ago time, parking without power steering was a bit more work than we wanted to do. There was more mechanical advantage, and thus less force required, to turn the wheel all the way to the stop if the amount you had to turn the wheel was more than 180 degrees. In order to do that, you had to go hand over hand, and it was helpful if the rim of the steering wheel was pretty much in the same place no matter where the front wheels of the car was facing because when you’re looking out the rear window of the car, you can’t keep track of where the rim of the steering wheel happens to be.

So I started thinking about how Tesla could deal with issues like this now that they’re putting the yoke steering on the Model S. I’d have dropped this essay a week ago if I’d been able to figure it out, but I was unable. Today, I decided to consult the Oracle of YouTube to get an answer. The trouble with consulting YouTube is that some of the people who put up videos aren’t any smarter than I am. I checked out a few of those videos. One had a guy who put a model of a yoke on his regular steering wheel and tried to steer with just that part of the wheel. He could, but it didn’t tell me anything about what the engineers at Tesla were probably thinking. Another guy actually used a hacksaw on his steering wheel to make it into a yoke. He could steer, but that was also not enlightening. Finally, I found a YouTube video that gave a theory that I could get behind.

To me, a steering yoke makes sense only if you don’t need to turn the yoke any more than ninety degrees in either direction, just the way it is in an airplane. That way, there’s no hand-over-hand movement when you’re not looking at the steering wheel. I was stumped by this because steering would be too quick at highway speeds. There are already collisions when someone jerks the steering wheel too hard. These would be more frequent if the steering was so sensitive to slight movements.

The video gives the answer. What you don’t see in the pictures of the yoke steering are pictures of the steering mechanism. Now remember, the person who made this video is theorizing. I’m writing about the video because I believe his theory is correct. The person who made the video goes by the moniker, TenXchange.

Here’s the theory. Tesla is eliminating the traditional rack and pinion steering in which the steering wheel is physically connected to the steering mechanism by a stiff rod. Instead, the steering yoke is electrically connected to the steering mechanism, a steer-by-wire system. That’s helpful for two reasons.

First, there can be a variable steering ratio. When you’re going fast, on the highway, steering the car is less sensitive so a quick jerk on the wheel will make your car point in the direction you want to go, but it won’t send the car into an uncontrolled skid. When you’re going slow, and parking the car, you won’t need to turn the yoke very far to get the wheels in the direction you want them to go, and you won’t need all that hand-over-hand motion of the steering wheel to get the car parked. In between, on city streets when you’re not going as fast, the steering ratio can be more sensitive than on the highway but less sensitive than when parking.

The second reason for having steer-by-wire according to TenXchange is that there will come a time when your Tesla with FSD will actually be autonomous. You may want to send your car out to work as a taxi for you while you stay home and do something else, or you might just want your car to be your chauffeur while you do something else besides driving. I have to say that even though I paid for FSD when I bought my Tesla a year or so ago, I’ll be surprised if this happens in my lifetime. Anyway, if actual FSD does come to pass, and if my car is a much safer driver than most human beings, then I wouldn’t want a human being to be able to take over the driving by just turning the steering wheel or tapping the brake. That could cause an accident.

My car won’t ever have steer by wire or brake by wire since it doesn’t have those things now, and I doubt that Elon Musk is going to recall half a million Teslas with FSD in order to convert them to steer-by-wire and brake-by-wire. But the newer cars, the ones with yoke steering, may well have those features.

Tesla has an event to release the first redesigned Model S cars to owners on June 3rd.

First Look at Tesla's V12 User Interface, Full Screen Visualizations and New Media Player [Updated: Photos and Video]

Tesla's latest V12 user interface will change the look and feel of some of the vehicle’s operations. This new interface, announced on X, is already partially available on the Cybertruck but will now be rolled out to the Model 3 and Model Y, equipped with AMD Ryzen processors according to Tesla. However, the new Model S and Model X will likely receive it as well, although possibly not at the same time. It integrates several new features and aesthetics that set new standards in vehicle interface design.

The new interface will become available in Tesla update 2024.14, which started rolling out to employees yesterday.

New Parked Vehicle Visualization

A standout feature of the v12 UI update, not to be confused with FSD v12, is the centralized vehicle visualization, which dominates the display while parked (video below). This design choice enhances visual appeal and improves functionality by placing critical vehicle performance metrics, and status updates front and center. Similar to the layout in the Cybertruck, this feature provides drivers with a clear and immediate view of their vehicle's status and shows off the gorgeous 3D model.

New Media Player

There’s a new media player that’s larger and easier to use. By increasing the size of the media player, Tesla is now able to fit additional options that were hidden before, such as EQ and audio settings, the search icon and shuffle and repeat options.

The new media player appears while the vehicle is parked, driving or while the visualizations are in full-screen mode.

The media player is available on the Model 3 and Model Y and according to Tesla it’ll be limited to vehicles with the Ryzen-based infotainment center.

Improved Navigation

The navigation system will see several improvements. You’ll now see a little trip progress bar that lets you visually see how far along you are on your route.

If your vehicle has a rear screen, as in the new Model 3, the redesigned Model S or Model X, then trip information such as ETA will also be displayed on the rear screen.

Tesla already has the ability to update your route if a faster route becomes available. You can change some of these settings under Controls > Navigate. However, now the vehicle will show you if a faster route becomes available and gives you a chance to cancel the updated route if needed.

Expanded Autopilot Visualizations

Tesla is now bringing its full-screen visualizations outside of North America. However, there will be some improvements as well. In addition to being able to have the visualizations go full screen, there will now be a small map displayed in the corner as well.

That’s one of the issues with the full-screen FSD visualizations right now. If you make them full-screen, you lose your navigation map completely and only have the next turn available.

This will be the first time full-screen visualizations are available outside North America. It’s not clear whether all the FSD visualizations will be available such as traffic lights, curbs and more will be displayed, but Tesla has slowly been adding additional visualizations for non-FSD users, so there’s a chance that this feature will finally display all FSD visualizations to users outside of North America.

It’s not immediately clear whether this feature will require Enhanced Autopilot (EAP) or FSD.

Update: The full-screen visualizations do not require FSD or EAP, but unfortunately the visualizations displayed are still the same ones as in previous updates, so it won’t display the surrounding environment and curbs.

Full-Screen Browser Support

With this update, Tesla will finally let you manually make the browser full-screen. While this will make Tesla’s Theater apps a little redundant since they just loaded the website of the selected streaming service, you’ll now be able to stream any video service full screen, as long as the service supports Tesla’s browser.

As expected, the full-screen button will only be available while the vehicle is parked.

Checking Compatibility

Owners can verify their vehicle’s compatibility with the new full-screen visualizations while parked and driving by navigating to Controls > Software > Additional Vehicle Info on their Tesla’s touchscreen. This update is tailored for Tesla vehicles equipped with the AMD Ryzen processor.

Tesla's Next FSD v12 Update Will Be Available For Users on 2024.8

By Not a Tesla App Staff

Tesla will soon roll out a FSD v12 which is compatible with update 2024.8 Tesla began its public rollout of FSD v12 last month, which brings a much more refined, human-like experience to the self-driving software.

To celebrate the achievement and show owners how big of an improvement FSD v12 is, Tesla offered a free month of FSD to all owners with compatible vehicles in the U.S. and Canada.

However, there was a caveat. The latest FSD v12 (v12.3.4) is Tesla update 2024.3.15. Since Tesla doesn't roll back updates since the process isn't rigorously tested, that means many owners who had already received Tesla update 2024.8.9 were left without a free trial and access to FSD v12.

Subscribing to FSD on Update 2024.8

In fact, if you're in the U.S. or Canada and subscribe to FSD while on update 2024.8.x, you'll actually receive the older, and quite a bit worse FSD v11.4.9.

The FSD v12 update has been highly anticipated and aims to finally upgrade Tesla’s ADAS level 2 system to something higher. Musk has talked about level 4 or 5, and even recently said Tesla is going all-in on FSD.

FSD v12 for Update 2024.8 Is Coming

Rohan Patel, who recently left Tesla, recently said that Tesla is already working on an FSD v12 update that is compatible with users on update 2024.8.x. This means that the next FSD update may finally be based on the 2024.8 codebase.

However, just this morning Tesla released the next major update to the platform, update 2024.14 for employee testing. The update is massive and includes an updated UI, hands-free trunk opening, a full-screen browser and more.

However, Patel never specified which codebase the next FSD update would be based on. If it's based on update 2024.8, then users who are upgraded to 2024.14 in the next couple of weeks may face a similar fate as users on 2024.8 today.

Release Date

Patel said to expect the release of the next version of FSD v12 this week. Since update 2024.14 is still being tested with "wave 1" employees, we'll likely see one of two things happen. We may see the next FSD update be based on 2024.8 and released very soon, or it'll be based on update 2024.14, but it may not be available for another couple of weeks.

Once this update arrives, owners with a Tesla on 2024.8.x will finally be able to update and receive their one-month trial of FSD v12 and finally experience what everyone has been excited about.
