Tesla Semi tire inflation patent paves way for pickup truck, Model Y & X’s off-road abilities

Published

During Tesla’s third-quarter earnings call, Elon Musk noted that the company continues to make headway on its future vehicles. Musk noted that he had already approved the production of the Model Y prototype, while pointing out that the company is making progress on the next-generation Roadster and the Tesla Semi. Musk reiterated his enthusiasm about the Tesla pickup truck as well, which he admits is a vehicle he is most excited about.

Some of the improvements to the Tesla Semi appear to have been teased in one of the company’s recently-published patent applications. The patent, which was published on October 18, 2018, and titled “Automatic Tire Inflation System with Thru-Hub Air Feed,” outlined a system enabling Tesla’s vehicles to inflate or deflate their tires as necessary. While several vehicles today already have Automatic Tire Inflation Systems, Tesla’s patent application notes that conventional ATIS have much room for improvement.

“These prior solutions had a number of shortcomings. With some prior art techniques, air was fed through hollow drive axles to a fitting located on the end thereof. The fitting was then coupled to the air inlets of the tires. To couple the air into the hollow drive axles, a rotatingly attached fitting coupled air from an air storage to the inside of the hollow axles. This fitting was subject to leakage of contaminants. These contaminants interfered with the operation of the ATIS and eventually caused the ATIS to fail.”

Tesla’s ATIS patent involves a system that features valves, a rotary air seal, and bearings, to avoid contamination. With such a system in place, Tesla notes that the wheels of its vehicles would likely last longer, and tires would require even less maintenance.

“In order to overcome the shortcomings described above among other shortcomings, an Automatic Tire Inflation System (ATIS) for use with a vehicle according to a first described embodiment includes a controller, valves controlled by the controller, the valves having an air supply inlet, and a plurality of air outlets. Further, the ATIS includes, for at least one drive axle having inner bearings and outer bearings, a channel formed in a spindle, first hosing coupling a valve of the valves controlled by the controller to the channel formed in the spindle, a channel formed in a hub, a rotary air seal residing between the inner bearings and the outer bearings and coupling the channel formed in the spindle to the channel formed in the hub, and second hosing coupling the channel formed in the hub to at least one wheel.

“Thus, as compared to the prior ATIS systems, the ATIS of the first embodiment, significantly reduces contamination in the ATIS air stream. Reduction in contamination extends the life of the ATIS, extends spindle life, extends hub life, and extends serviced wheel/tire lives and extends maintenance intervals.”

While the diagrams in the patent application suggest that Tesla’s upcoming ATIS would be used for the Semi, the applications for the automatic tire inflation system for the company’s other, upcoming vehicles are notable. Having the capability to automatically inflate tires depending on the terrain, after all, would allow Tesla to start giving its vehicles some form of off-road capability. Under-inflated tires are key to off-road driving, since they are capable of flexing more, allowing vehicles to “crawl” over rocks and other sharp, irregular terrain. Under-inflated tires also have a wider contact path, allowing vehicles to gain more traction in terrain like deep sand or soft snow. 

For now, Tesla’s vehicles are optimized for city and interstate driving, and while there are accounts of the Model X being taken off-road (EV YouTuber Bjorn Nyland’s extreme driving test sessions come to mind), the company’s electric cars are yet to have features that are specifically geared towards off-road driving. With an ATIS system, Tesla’s upcoming vehicles such as the Tesla pickup truck, and even the company’s SUVs like the Model Y and a future iteration of the Model X, could have the ability to explore areas beyond paved roads. Such capabilities would likely be invaluable, considering that legendary vehicles like the Ford F-150 and the Chevy Blazer established their legacies by proving themselves capable in areas where neither asphalt nor concrete is present.

Tesla clears the air on Cybertruck ‘deactivation’ video that is obviously fake

Tesla has cleared the air on the viral video, stating it is fake.

Tesla has cleared the air regarding a video that has been circulating, where the owner claims his Cybertruck was “deactivated” by the company while he was driving.

The video was shared on X and showed a driver pulled over on the side of the road, claiming his Cybertruck had been deactivated by Tesla in the middle of traffic. It is very obviously fake to those who know the company, but these kinds of things have a tendency to pick up steam.

The video shows a screen that says:

“Tesla Cybertruck De-Activated. Critical Issue Detected | Contact Customer Service, Comply with Cease & Desist to Re-Activate. Update Failed, Return to Dealer.”

The same person who posted the video also shared an image of what appears to be a Cease and Desist letter from Tesla, but it is also likely fake:

The company finally responded to the video on Monday afternoon, stating that the video is, in fact, fake, reiterating that it will not disable vehicles remotely for any reason.

It is a shame that these types of things happen, especially as people are prone to believe anything they see on the internet. As there is so much misinformation circulating surrounding Tesla and its CEO Elon Musk, it is no surprise that someone would leverage the situation for their own benefit.

If that Cease and Desist letter is not real, perhaps the next one might be. These types of things can truly cause damage to a company’s reputation, and someone getting an idea that Tesla would remotely deactivate a car could prevent them from buying one.

Elon Musk is stepping up for Tesla Service in a big way

Elon Musk has stepped up to resolve a handful of customer issues regarding vehicle service.

Elon Musk is stepping up to help customers in a big way, especially when they are having issues with Tesla’s Service.

Perhaps one of the biggest advantages Tesla owners have is access to Musk through X, his social media platform. Over the years, we’ve seen Tesla add features, refine its cars’ performance, and more, all through asking Musk directly through a post.

Now, Musk is stepping up in another way by resolving a few Service complaints that customers had.

The first occurred last week when a recall on a Tesla battery was not honored by Service. The company sought $30,000 for a replacement and labor, which was not right. Musk responded that he would personally investigate the matter. The vehicle was fixed at no cost as it was a recall, and was ready for pickup the next day.

It also revealed a new strategy Tesla is using to combat service communication issues:

Tesla creates clever solution to simplify and improve its Service

The next occurred with a Cybertruck owner who was in Japan. Their car was parked at an airport in the U.S. and had lost a vast majority of its state of charge, leaving them just fifty miles of range at the time.

Musk reached out to the owner and said Service will take care of the car and will investigate the cause of the battery drain:

There are not too many companies out there where the CEO will get involved with individual issues like these. It’s pretty exclusive to Tesla, as Musk has commonly stepped up to resolve complaints with vehicles or to confront features that some owners might find useful.

Service has been a weak point of the company for some time, but it has worked to refine and resolve customer complaints by building more Service Centers across the world that can handle these issues.

Tesla CEO Elon Musk confirms Robotaxi is opening to the public: here’s when

Anyone will be able to request a Tesla Robotaxi in September, Elon Musk said this morning.

Tesla CEO Elon Musk has confirmed that the company’s Robotaxi platform is opening to the public, and he even gave a timeline for when anyone will be able to access one for a ride.

Tesla’s Robotaxi platform launched to a small group on June 22 in Austin, Texas. The company has continued to expand the number of riders and its geofence over the past month and a half.

Tesla officially launches Robotaxi service with no driver

Additionally, it launched rides in the Bay Area of California, but it differs slightly, as the Texas Robotaxi platform does not utilize a Safety Monitor in the driver’s seat. In California, the monitor sits in the driver’s seat.

As the geofence, service areas, and testing populations expand, Tesla fans are awaiting their elusive emails that enable their ability to use the Robotaxi platform. It now seems that the email will come soon, as Musk said Tesla will open up public access to Robotaxi next month:

Tesla has been prioritizing safety over anything else with the launch of the Robotaxi platform, which is why it has been slow to push invitations to new riders. It is confident in the abilities of the platform and its Full Self-Driving suite, which has been proven with data.

However, even a single accident could set Tesla back years in terms of its development of self-driving cars. It is not a risk it is willing to take.

Musk said during the recent Q2 Earnings Call:

“We need to make sure it works when the vehicles are fully under our control. It’s kind of one step at a time here. We don’t want to jump the gun. As I said, we’re being paranoid about safety. But I guess next year is I’d say confidently next year. I’m not sure when next year, but confidently next year, people would be able to add or subtract their car to the Tesla, Inc. fleet.”

As the platform will expand in Austin and the Bay Area for anyone, Tesla still continues to reiterate that Robotaxi will be available for everyone sometime next year, as Musk said in the quote above.

Things will continue to improve over time, and Tesla will likely expand its geofence in both regions in the coming weeks. It has already done that in Austin twice, with about a doubling in size occurring both times.
