The user experience of Tesla’s electric cars is centered mostly on the vehicles’ large, high-resolution displays. Coupled with custom software that provides a quick, smartphone-like experience, Tesla’s screens in its vehicles are already among the best in the auto industry. But in the spirit of the company’s habit of constant innovation, it appears that Tesla is looking to improve the quality of its displays even more. 

A recently published patent from the electric car maker, titled “Holographic Decorated Glass for Screen Color Matching,” outlines a way for the electric car maker to improve the viewing angles of its vehicles’ displays. In the patent, Tesla notes that “because display screens typically have a periodic micro-structure (e.g., a pixelated structure), the color of the display screen may be dependent on the angle at which a viewer is looking at the display screen.” This results in viewing angles that have significant room for improvement, even among high-quality screens. 

“The non-displaying portions of the device may be unable to match this angular color dependence of the display screen, resulting in a readily visible boundary between the display screen and the non-displaying portions of the device. Accordingly, there is a need for better color integration between the displaying portions of a device and the non-displaying portions of the device,” Tesla wrote.

To address this, Tesla opted to utilize a pigmented frame and index match glue to coat its vehicles’ screens, as well as a holographic glass panel. By adopting these techniques, Tesla expects to provide its vehicles with a screen that can offer optimal viewing angles for all passengers. This is especially useful when paired with the company’s entertainment features such as Tesla Theater or Tesla Arcade, which are accessible when a vehicle is on Park. 

Tesla describes its use of index match glue and holographic glass panels as follows.

“Index match glue 206 may change the perceived color and appearance of display 204 to match the color and appearance of surrounding frame 202 within a small range of viewing angles. For example, index match glue 206 may change the perceived color and appearance of display 204 to match the color and appearance of frame 202 within a range of viewing angles approximately normal to the surface of display 204. However, due to the angular dependence of the perceived color and appearance of display 204 (due to display 204 having a holographic structure resulting from the pixels of display 204), index match glue 206 may be unable to change the perceived color and appearance of display 204 to match the color and appearance of frame 202 within a broad range of viewing angles so that the boundary between frame 202 and display 204 is invisible to a viewer. Accordingly, with display 204 coated with index match glue 206 surrounded by frame 202, the boundary between frame 202 and display 204 may still be readily visible at certain viewing angles.”

“The directionality of the periodic structure of holographic film 402 may approximate or match the directionality of the periodic structure of display 406. For example, if display 406 includes a plurality of periodic features (e.g., pixels) oriented in a first direction (e.g., rectangles, triangles, or the like having a common orientation), holographic film 402 may include a plurality of periodic features oriented in the first direction. FIG. 5 shows exemplary system 500 in which the visibility of a boundary between display 504 and a surrounding frame including a holographic structure (here holographic glass panel 502) may be reduced or eliminated over a broad range of viewing angles. In exemplary system 500, a periodic structure is formed on holographic glass panel 502 directly. For example, laser etching on holographic glass panel 502 may produce the periodic structure responsible for the holographic effect of holographic glass panel 502. Holographic glass panel 502 may include holographic structures formed in a variety of other ways, including ablation, etching, deposition processes, and the like.”

A color-matched display with optimal viewing angles might be a rather minor aspect of a vehicle, but for connected cars such as Teslas, it is these little things that make a difference in user experience. A car that boasts some of the most advanced automotive tech available in the auto segment today, after all, deserves a screen that is on par with some of the best mobile devices on the market.

Tesla’s display design outlined in its recently published patent can come in handy as well, particularly as the electric car maker introduces more updates to its fleet of vehicles. Among these is a “Fade Mode,” which Elon Musk has hinted at in the past. While responding to a Twitter follower last year, Musk responded positively to the suggestion of adding an option that allows drivers to dim their vehicles’ display while a car is in motion. This, together with features like V10’s Joe Mode, could help make long trips in Tesla’s electric vehicles much more convenient for passengers.

Tesla revealed a major new Cybercab detail in a guide it released for First Responders, showing new territory in its beliefs and intentions for the ride-hailing-focused vehicle that entered production in April.

The First Responders Guide is released to give fire departments, paramedics, and other emergency personnel the proper guidance on what to do in the event of an accident, entrapment, or other situation that would require immediate attention.

On one of the pages of the First Responders Guide, Tesla revealed a stark detail about the Cybercab, which could help personnel enter the vehicle more easily in case of an emergency.

It shows Tesla has no intention of releasing any Cybercab units that were initially proposed for ride-hailing services for the general public with any manual controls, meaning a steering wheel or pedals:

“A Cybercab equipped with steering wheel, brake pedal, and an acceleration pedal is typically an engineering or test vehicle, and operates at SAE Level 2 autonomy. Cybercab is not typically equipped with a steering wheel or acceleration and brake pedals.”

This is a major development for those who continue to believe Tesla planned to release the Cybercab with any sort of manual controls so that passengers could take over if needed. However, when Tesla started manufacturing production versions of the Cybercab in Giga Texas earlier this year, they were spotted without a steering wheel or pedals.

It essentially confirms the company has no intentions of bringing manual controls to the car’s production versions. Some have argued that the likelihood of Tesla having something

There still are some Cybercab units out there with a steering wheel and pedals, and as Tesla said, these cars are engineering or test vehicles, which have Safety Monitors on board to help the car out of a precarious situation or emergency.

Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.

Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.

Here are the full release notes for the suite:

  • Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
  • Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
  • Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
  • Introduced parking, unparking, and reversing capabilities.
  • Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
  • Speed Profiles are now available at all times, to further customize driving style preference.

These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.

He added:

“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”

Tesla will continue to roll out the v14 Lite suite more widely in the coming weeks, the company said.

Tesla has finally released its Full Self-Driving v14 ‘Lite’ suite for older cars that equip the Hardware 3 or AI 3 chip, which have not been able to handle the newest versions of the company’s driver assistance software.

Tesla officially started releasing the v14 Lite suite to owners in the Early Access Program last night. The company’s Head of AI, Ashok Elluswamy, said that the rollout will continue over the next few weeks. The build distills the driving behavior from AI4’s v14 series into both the camera and compute configurations of an AI3 car.

It also includes a variety of new features that were available to AI4 cars running v14, including:

  • Start Self-Driving from Park
  • Arrival and Parking Options
  • Speed Profiles

The release is highly anticipated because those owners with AI3 vehicles were early adopters into the FSD platform and were promised that their cars would be capable of achieving Full Self-Driving.

However, Tesla CEO Elon Musk admitted during the company’s recent Q1 Earnings Call that these vehicles would not be capable of achieving unsupervised Full Self-Driving, which is what Tesla had originally said.

Owners were not pleased with this answer, or the idea that their commitment to buying the suite outright for thousands of dollars would not yield the ability to drive without operating the car. Tesla gave some solutions for this, including a discount on a new car, or an upgrade to an AI4 or AI5 self-driving computer and new, upgraded cameras.

Tesla owners do not seem pleased with these options, as they require giving the company more money.

Nevertheless, it is important to note that Tesla came through for owners here by releasing v14 Lite before the end of Q2, something it had promised owners during the previous Earnings Call. Tesla has had trouble keeping up with timelines, but this is a big achievement for the team.
