Tesla Model S Steering Wheel Will Work Using Steer By Wire

May 25, 2021

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.

Tesla May Improve Car Wash Mode With Window Alerts

There are a few features to keep in mind when taking your Tesla through a car wash, but Tesla’s Car Wash Mode makes it easy by enabling or disabling several features for you. These settings don’t only prevent damage to your vehicle, such as locking the charge port door so that it doesn’t automatically open when a cleaning brush touches it, but they also improve the experience by recirculating the air in the vehicle to prevent cleaning chemical smells from coming in.

Car Wash Mode makes it easy by giving you a checklist of items and their real-time status, alerting you of any important items, such as your trunk being open.

When activated from Controls > Service > Car Wash Mode, it performs a list of actions:

Automatically closes all windows
Locks the charge port door to prevent accidental opening
Disables automatic windshield wipers
Turns off Sentry Mode
Disables the walk-away door lock
Silences Parking Sensor chimes
Enables easy access to the Fold Mirrors and Free Roll options (you can also put your vehicle in neutral through the gear stalk)

What About Your Windows?

While Car Wash Mode monitors more than a handful of items, it doesn’t continuously check the status of your windows. When you first enter Car Wash Mode, the vehicle will automatically roll up any open windows. However, it won’t alert you if a window has been lowered after Car Wash Mode was enabled. This could spell disaster for your vehicle's interior, as one user found out.

Lincoln posted a video on X, demonstrating what happened to his friend and requesting that Tesla add open windows to the list of flags in Car Wash Mode.

Tesla’s Troy R. Jones, VP of North America Sales and Service, noticed the post and decided to take action, offering to pass on the suggestion to the vehicle software team.

Good recommendation. Sharing with the team. Thanks

Potential Improvements

While Troy’s response doesn’t confirm the feature being added in a future update, it’ll at least be put in front of the software team to potentially address.

Tesla could add this window-specific solution in several ways. Tesla could add this as another on-screen flag while the vehicle is in Car Wash Mode, simply alerting the driver that there’s a window open. However, they could also go one step further and lock the rear windows to prevent accidental opening while Car Wash Mode is enabled.

In case of an emergency, Tesla could present an on-screen button that pops up when a user tries to open a window while Car Wash Mode is activated, letting the driver override Car Wash Mode.

We’re interested to see what Tesla would do here, as these little quality-of-life changes really improve the end-user experience. What else would you like to see added to Car Wash Mode?

Houston Neighborhood Offers a Glimpse of the Future With Tesla-Powered Smart Homes

Tesla offers a range of home energy products — from the widely used Wall Connector to the Powerwall and the innovative Solar Roof. Now, for the first time, a unique residential development in Houston, Texas, combines all of these technologies — and more — to move toward energy self-sufficiency.

Self-Sufficient

This community, located in Oaks of Shady Acres and built by Utopia Homes, consists of just 11 townhomes, each designed using Tesla technology to be self-sufficient. Utopia has equipped the homes with Solar Roofs, Powerwalls, and Wall Connectors to complete the entire ecosystem.

Tesla’s Solar Roof replaces traditional roofing materials while doubling as a clean energy source during daylight hours. The best part is that it mimics the look of conventional shingles while improving durability and longevity. Any excess energy generated is stored in the home’s Powerwall 3 units, providing power when the sun is down.

Tesla’s Universal Wall Connector, which can charge any EV equipped with either a NACS or CCS port (through a J1772 adapter). If you added on a Cybertruck with Powershare (more vehicles will support Powershare in the future), you’d have a backup system that would last an extremely long time on batteries alone.

A Powerwall 3 stores about 13.5 kWh of energy, while a Cybertruck has a battery pack of 123 kWh, which is roughly equivalent to about nine Powerwalls. In addition, the Cybertruck could be used as a “mobile battery pack,” which can get additional energy from Superchargers and bring it back to the home if there’s an extended power outage.

Utopia markets these homes with “100% energy security,” - but they’re still grid-connected. However, they appear to have made quite a point with this - as many people in Texas, with its notoriously unstable electricity grid - were excited to get into these homes.

Sadly, these homes still include a gas range, so they’re not entirely green and disconnected. This likely comes down to the fact that powering an induction range alongside a heat pump in the winter could draw more energy than Powerwall 3 is capable of outputting instantaneously.

Attention Getters

These 11 homes attracted a lot of attention - according to a broker working on Utopia’s team, they had requests to see or buy these homes coming from across the country. Priced around $544,900, these homes are about $150,000 higher than Houston’s median list pricing for similarly sized townhomes, but the benefits are clear for many buyers who will recoup these additional costs over the home’s life.

Utopia has acknowledged the demand for Tesla-powered and future-proofed homes like these and is already planning to build more in the future. This is an excellent showcase of what an electric-powered future could look like, and we’re excited to see more of these types of homes and neighborhoods in the future.
