Tesla has submitted a patent that would improve its Semi-truck’s centered seat design by utilizing a suspension system on the architecture of the driver’s seat to add additional safety to the operator of the vehicle.

The patent notes that scissor-lift designs are commonly used in large vehicle seats, like in a semi-truck. This design includes pivoting legs that cross each other, allowing seats to be adjustable. However, this architecture has some drawbacks, especially when an accident occurs. In the event of a collision, the “all belts to seat” (ABTS) development requires the frame of the seat to withstand the expected loads of the occupant and distribute them to the vehicle body. However, the scissor-leg designs were not originally intended for ABTS solutions and are not efficient at distributing the loads,” the patent states. The intention is to make the seat safer and more comfortable, an idea that could save drivers of the Semi in the long run.

“For a driver, adjusting the height of the seat can be important in ensuring a safe driving position. For a passenger, height adjustment can provide increased comfort. Truck seats with scissor-lift designs can be raised or lowered using an airbag positioned underneath the seat, with the scissor legs being more, or less, extended based on the state of inflation.”

Safety and comfort are of the utmost importance to truck drivers, as many of them are traveling across the country in the Semi they are operating. Many drivers work at a rate of pay that depends on the number of miles they travel in a given shift. This can attribute to long periods of time behind the wheel, making it important for the driver to feel comfortable and safe at all times. According to the Federal Highway Administration, truck drivers can travel between 45,000 and 100,000 miles a year. This makes it pertinent for truck-makers to design vehicles that are comfortable enough to allow extended driving sessions.

The design Tesla is proposing would increase safety in the event of a crash, while also benefiting drivers of different heights. When adjusting the height of the seat, the driver is inflating or deflating an airbag to either raise or lower their positioning. Depending on the inflation of this airbag, the spring force can change, and this can cause differing results in the event of an accident.

“Many seats feature suspension for the comfort of the occupant. In truck seats with a scissor-lift design, the airbag also serves as a spring to provide suspension, and a damper can be added to absorb shock. However, because the airbag is also used to control the seat height, ride characteristics are affected by the height adjustment,” Tesla states in the patent’s background.

Tesla plans to include this suspension system by having a “multi-post architecture” that would couple sleeves to sets of lift links. They also plan to modify the height adjustment system that would coincide with the seat’s suspension.

“The height adjustment system comprises a four-bar linkage. The height adjustment system is positioned on top of the suspension system. The vehicle seat further includes a plate riding on the suspension system, the sleeves are coupled to the plate, and respective first ends of the pairs of lift links are pivotally coupled to the plate. The multi-post architecture includes posts coupled to a plate configured for fore/aft adjustment on a track,” Tesla wrote.

Overall, Tesla seems to be designing its Semi to be the safest tractor-trailer on the road, hands down. Safety is a priority for the company to begin with, but the development of new methods to create a safer driving experience stands strong and firm with concepts outlined in by the company in these recent patent applications.

The Semi has been ordered by multiple companies that are looking for a more environmentally-friendly logistics option. It will begin a limited production sometime in 2020.

Tesla Model Y L gets suspension complaints in over odd issue China

Published

The Tesla Model Y L is arguably the most hyped trim of the all-electric crossover, other than the Performance configuration that comes with white-knuckle speed and sports car-level handling.

However, it is not all perfect. Tesla owners in China who took delivery of the Model Y L, denoted with an L to highlight its longer wheelbase, are experiencing what they are referring to as “collapsing” of the rear wheels, as suspension issues appear to be an issue with some of the builds.

The gap between the wheel arch and tire has narrowed to the point that “not even a single finger” could fit, according to a report from Car News China. The failures are not tied to a specific mileage, as one owner said that after just 9,000 kilometers (5,600 miles), they noticed the suspension issue when their car was fully loaded.

Another one had the issue at 30,000 kilometers (18,640 miles) and noticed that the wheel gap shrank to two fingers, so not as drastic as the person who reported a similar issue at 9,000 km.

Tesla Model Y L is gaining momentum in China’s premium segment

Along with the visual recognition of the issue, others are saying the sagging is causing abnormal wear on the inside of the tires. Extra weight and instant torque already provide additional stress on the tires in electric vehicles during normal operation, so it is no surprise that this is another complaint.

There has been no recall issued by Tesla, and the company has not yet publicly acknowledged the issue.

Some are suggesting that owners use a “finger test” to self-diagnose whether there is an issue with the suspension. There should be four fingers between the tire and the wheel well; anything less than that starts to get dicey.

Tesla Cybercab event gains steam ahead of massive launch

Published

Tesla is starting to truly tease and hype its groundbreaking Cybercab event, which takes place tomorrow in Austin, Texas. It will be the first time members of the public will be able to ride in a Cybercab, a vehicle without any manual controls, on public roads.

Tesla has been dropping some hype on X over the past several days, but this morning, the excitement has truly started to build up for the event. Although Cybercab has been unveiled before, this is truly Tesla’s announcement that it is ready to start offering autonomous rides for public passengers in its new ride-hailing-geared vehicle for the first time.

The hype has started with a variety of different social media posts that are a true indication that Tesla is preparing for something big. Teasing so much of the potential of Cybercab, including its ability to truly revolutionize how people hail rides for local travel, is what the big idea for the event entails. The time that many Tesla owners, fans, and investors have been waiting for is potentially here:

The event has remained slim on details. Even invitees are still awaiting true details about what the event will entail, where they’ll go, and what is in store for the evening. This is pretty typical for an event run by Tesla; they keep things under wraps for the most part until the very last minute.

However, there is no secret about what the real intention of Tesla is for this event: it is going to be a huge reveal party for a vehicle that has no steering wheel and no pedals. It is a truly massive step for the company moving forward.

Speculation persists as to whether this is going to be an event that simply announces that rides will begin with the Cybercab, or it will be something more substantial. Tesla has said in the past that they plan to sell the Cybercab to the general public in what could become a great way to earn passive income by adding it to a more global fleet of Robotaxi-geared vehicles.

Tomorrow, the show begins in Austin, and the Cybercab goes live at some capacity; we just don’t know exactly how quite yet.

SpaceX tells the FCC that Starship Flight 14 is going to orbit

SpaceX filed with the FCC for Starship Flight 14, its first true orbital launch attempt.

Published

on

By

SpaceX has asked the Federal Communications Commission for permission to fly Starlink terminals during Starship’s fourteenth flight test, and the filing lays out a genuine trip to orbit, something the program has never attempted.

Every Starship flight so far, including Flight 13’s successful splashdown in the Indian Ocean on July 24, has flown a suborbital arc that ends with the ship reentering the atmosphere within the same hour it launches. The FCC paperwork describes a mission profile built around an actual orbital insertion instead.

The payload is the other half of the story. Flight 13 carried 20 production Starlink V3 satellites, but because that mission never reached orbit, the satellites reentered along with the ship rather than joining the constellation, something Teslarati covered in detail after SpaceX released footage shot from one of those satellites as it drifted away from Starship in space. Flight 14 is designed to close that gap. If the orbital insertion holds, the roughly 20 V3 satellites onboard would separate into an operational orbit and could eventually go into service, each one rated for about 1 terabit per second of downlink capacity by SpaceX’s own account.

SpaceX announces new Starbase for ‘thousands of Starship launches annually’

Elon Musk first flagged the orbital attempt during SpaceX’s August 4 earnings call, the company’s first as a public entity following its June IPO under the ticker SPCX. He also floated catching the ship with the Starbase tower on the same flight, an idea he walked back on August 20, saying the catch attempt would more likely come “in a few months,” as Teslarati reported at the time. Flight 14 will instead target a splashdown for the ship in the Indian Ocean, the same recovery method used since Flight 12.

Hardware has been catching up to the ambition. Booster 21 completed a full 33-engine static fire on August 28, and Ship 41 finished its own six-engine test the week before. An airspace briefing circulated to pilots on August 20 listed September 15 as the target date, later than the end of August window Musk mentioned on the earnings call, though SpaceX has not confirmed a launch date publicly and Starship schedules routinely slip while hardware and FAA paperwork line up.

The FCC filing itself does not guarantee a launch date. It covers communications authority, and not flight readiness, considering SpaceX still needs Ship 41 fully stacked and cleared by the FAA before Flight 14 can fly. But the filing is a real marker of intent and it puts a specific regulatory process behind what had so far only been Musk’s word on the earnings call.
