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 brings Model Y L ‘Launch Series’ to the U.S. at $61,990

Published

on

Tesla has officially launched the Model Y L in the United States and Puerto Rico for $61,990. It is the longer-wheelbase version of the Model Y, and has been available in China since last year.

Tesla brings the Model Y L to the U.S. just months after it phased out the only pure SUV in its lineup, the Model X. It is slightly longer than the Model Y configurations that are already available in the U.S., and features a three-row, six-seat setup with Captain’s Chairs being among the many features that make this a truly fantastic offering.

The Model Y L is priced competitively at $61,990, and features 325 miles of range and a 0-60 MPH in just 4.4 seconds.

Tesla also added a handful of new features that are not available in even the Premium Model Y. Here’s a full list of its features:

  • Heated/Ventilated Front Seats with Powered Thigh Cushion
  • Heated/Ventilated Captain’s Seats in Second Row with Powered Armrests & One-Touch Fold
  • Heated Third-Row Seats with Power Recline, One-Touch Fold & Child Seat Anchors
  • Improved Airflow, Increased Efficiency, More Range
  • 89 cubic feet of trunk space
  • Upgraded Acoustic Glass and Suspension to Minimize Road Noise
  • Adaptive Damping for a Smooth, Stable Ride
  • Staggered Tires for Enhanced Grip
  • Larger Tailgate for Better Rear Visibility and Bigger Windows Overall
  • 16″ First Row and 8″ Second Row Touchscreens
  • 19-Speaker Immersive Tesla Audio
  • 50W Wireless Charging Pads with Active Cooling and Charging Ports for All Other Seats
  • FSD Supervised and Integrated Grok AI

Tesla is also delivering these first units as a “Launch Series,” which comes with additional features, such as:

  • Door Trim Puddle Lights
  • Suede Dashboard Wing
  • Exterior and Interior Badging
  • Floor Mats
  • Sill Plates

The launch of the Model Y L in the U.S. marks a huge offering from Tesla to U.S. consumers. People have been calling for Tesla to bring a larger car to the U.S., and it needed it more than ever now that the Model X is gone.

It is a huge accomplishment for Tesla to get the Model Y L to the U.S., and after reporting strong deliveries today, it will be interesting to see how this car impacts future quarterly delivery reports.

Deliveries for the Model Y L “Launch Series” are slated for September or October of this year.

Tesla just told us twice that Model Y L is coming to the U.S.

Tesla just told us twice that the Model Y L is coming to the U.S., and two social media posts definitely just tipped the company’s hand, as if they wanted it to be any other way.

The two social media posts basically confirm that the slightly longer version of the Model Y will be heading to the United States soon, and many have speculated that the company could launch the vehicle as soon as this weekend.

The first post was directly from Tesla, and it showed an incredibly long Dachshund, with words above that said, “Looking forward to the long weekend.”

Anyone who knows Tesla knows the company loves to troll its fans and have fun, and this is a perfect example of that. While not a direct acknowledgement, Tesla is very involved on social media, especially CEO Elon Musk’s platform X, and the company is well aware of what is being discussed within the community.

With recent sightings of Model Y L test mules in California, peeks of the vehicle at Giga Texas, and a large call for the car to come to the U.S., Tesla is simply stoking conversation with this.

However, the company also made another move that was recognized on social media. Tesla has a large gallery that includes photos of its products so media and others can use them. This gallery applies to the U.S. market specifically, unless otherwise specified.

Tesla uploaded a Model Y L to the Gallery last night:

This seems to be another indication that the Model Y L is coming to the United States.

Musk said last year that the Model Y L could make its way to the United States late this year, but it was not something that was set in stone by Tesla. The company definitely needs to establish something in the SUV market that is larger than the Model Y, and the Model Y L might be the answer.

Even still, there are consumers out there who would love Tesla to develop something even larger, like a competitor to the Tahoe or Expedition. Tesla has not really given much of an indication that it will go in that direction.

Tesla is using vehicle microphones to improve build quality: here’s how

Tesla is using the vehicles’ internal microphones to improve build quality, Vice President of Engineering Lars Moravy revealed recently.

It’s no secret that Tesla is always finding ways to make its manufacturing operations more efficient, accurate, and valuable. Constantly trying to make its cars better, the company has never placed any restrictions on what it will do to improve everything from panel gaps to paint.

As Teslas have been driving autonomously on the property of the Gigafactory Texas plant for a while now, Moravy revealed to Herbert Ong in a new interview that cars rolling off production lines now autonomously navigate themselves through a bumps, squeaks, and rattles (BSR) portion of the line. This helps to identify any loose or improperly installed internal parts.

The cabin’s microphones, which are used for a variety of things in ownership, simultaneously monitor any noises inside the vehicle while it rolls through the BSR portion of the production line. Moravy actually revealed that Tesla is trying to build “Full Self-Hearing,” an AI system that will detect minor imperfections so they can be corrected before delivery.

It’s no secret that build quality is something that Tesla struggled with as it scaled to a fully massive production operation that manufactures over 1.6 million vehicles per year. However, in recent years, especially, there have not been as many complaints. Tesla has truly improved upon its build quality and paint quality over the past several years, especially in the U.S.

Tesla’s ‘megacasts’ are key to massive build quality improvements

While those improvements have been evident, there are still some complaints; no automaker is perfect with this. But this step will now ensure that every single car that rolls off the production lines at Gigafactory Texas will be void of any creaks, squeaks, or squeals when it leaves the factory.

This measure is one of the most unique we’ve seen in terms of a strategy to avoid build quality issues, but it is not exclusive to Tesla.

Ford uses acoustic analysis AI to find abnormalities in seat motors, climate control units, and other components. Suppliers and OEMs will also use microphone arrays or particle velocity sensors in end-of-line stations.
