Tesla Patents Robotaxi Sanitization System - Reveals How It Will Work

Not a Tesla App

A new patent claimed by Tesla has revealed some additional details on the upcoming Robotaxi’s Sanitization System – which will automatically sanitize enclosed spaces. It discusses how Tesla expects to use this system, including some hints on the upcoming Robotaxi app. Rimac also recently announced their upcoming robotaxi, which looks a lot like what we may see in Tesla’s Cybercab.

Most interesting is that this patent isn’t strictly based on some specific systems in the Robotaxi itself but is rather based upon an overall routine and process for sanitizing enclosed spaces that are shared among multiple people, particularly around vehicle interiors. This means it is likely applicable to all of Tesla’s vehicles.

You can view the entire patent here, although we went through it all so you wouldn’t have to.

Sanitization

The sanitization patent is focused on observing and analyzing the conditions of the closed space and then generating a sanitization routine based on the conditions, and then finally executing it. This essentially means that the system will scan a vehicle, determine what kind of cleaning is required, and then conduct that cleaning.

Analysis - Interior & Exterior

Let’s take a look at the analysis portion first. There are a few key detection parameters – ambient temperature, humidity, the presence of pathogens or unclean air, and the presence or absence of certain conditions in the enclosed environment. Using a multitude of sensor data, including some from the vehicle itself, the system will create a sanitization plan.

The sanitization plan doesn’t just include the interior of the vehicle – but can also consider external parameters like weather and vehicle usage history. Rain, snow, and mud could be some pretty big factors for a Robotaxi cleanup, and taking these into account is essential.

How It’ll Clean

Once the plan is generated, the system will utilize various sanitization routines, based on the plan that was generated. This can include using the HVAC systems, using UV lighting, using steam generators, and a few other processes. The system can also take into account whether the sanitization process can be accomplished by the resources available – e.g. if there is a human or humanoid robot available to accomplish some of the tasks.

There are a few basic methods described in the patent on how Tesla expects to sanitize vehicles, including blowing warm air toward the steering wheel, doors and windows, and the central display to sanitize. It also has a method to expose various parts of the vehicle, including the seats and seatbelts, to a sanitizing UV light.

There are some interesting and unique methods – using active or passive elements to create heat and sanitizing surfaces like the central touchscreen. That’s not all – the patent also talks about tilting the vehicle’s central display to reflect the sanitizing UV light around the vehicle. Tesla has some unique ideas on how to implement its automated sanitization process.

If there’s additional sanitization needed, the system can cooperate with external service robots (possibly Tesla’s Optimus), to sanitize the interior and exterior of the vehicle. It can also direct the Full Self Driving system to adjust the vehicle’s orientation, exposing certain parts of the interior to sunlight.

When and Where to Sanitize

Tesla expects this sanitization routine to begin running immediately after a passenger exits the vehicle, reducing downtime as much as possible between potential passengers. If the sanitization system identifies that deeper cleaning is needed, the system will redirect the vehicle in need of cleaning to a cleaning location, while another vehicle will be directed to the next potential passenger.

There are some Robotaxi-unique features, such as a disinfecting spray system and special disinfecting UV light that are not present in any of Tesla’s current vehicles. Whether these current vehicles will receive a refit or a refresh to include these features remains up in the air at this time, however, the patent did notably use the Model Y as the figure vehicle.

Some other features, such as using humidity, temperature, seatbelt retractors, seat adjustment motors, and motorized vents – are already in every Tesla vehicle.

Killing Germs

One of the most unique things about this patent is Tesla has looked at various airborne pathogens – such as SARS-CoV-2 (COVID-19), amongst others, and identified what temperatures and humidities will kill these off. It will use this information to change the ambient environment in the vehicle to one unsuitable for pathogens to survive, helping to prevent illnesses from transferring from one passenger to the next.

We’re going to see some unique things at Tesla’s Robotaxi unveiling on 8/8, and some more details of how this system functions will probably come up then. Sanitization of Robotaxis is absolutely one of the key steps that will help to build Tesla’s ambitious Robotaxi fleet – and we’re hoping to see more on how they expect to charge Robotaxis in the upcoming weeks.

Is Tesla Planning to Add Steam Support to All Vehicles?

Not a Tesla App

Yesterday, we reported that Tesla updated their Steam integration on Model S and Model X vehicles. The update was part of their 2024 Holiday Update, but it looks like there may be more to this than a simple update.

Steam, a video game library app, makes it easy for users to buy or launch games on their computers. However, a couple of years ago, Valve, who created Steam, launched their own standalone device, the Steam Deck. The Steam Deck runs a custom OS based on Linux.

Steam Launch

When Tesla launched the redesigned Model S and Model X, Tesla introduced a dedicated gaming GPU with 16GB of RAM and touted the ability to play top-tier PC games in Tesla vehicles.

In 2022, Tesla finally launched the Steam app for the Model S and Model X as part of its 2022 Holiday Update. The Steam app runs Steam OS, the same OS as the Steam Deck in a virtual environment.

However, earlier this year, Tesla stopped including the GPU and Steam (Beta) in their vehicles, and we haven’t seen any updates to the Steam in quite some time. In fact, we thought Tesla was axing their gaming-on-the-go dreams.

SteamOS Update

The Steam app, which is still in Beta, is getting an interesting update for the Model S and Model X vehicles with the discrete GPU.

Those vehicles received an update to SteamOS 3.6 - the same version of SteamOS that runs on the Steam Deck. While nothing has visually changed, there’s a long list of performance optimizations under the hood to get things running smoother.

Comparing Steam Deck to Tesla Vehicles

Let’s take a look at the Steam Deck - according to Valve, its onboard Zen4 CPU and GPU combined push a total of 2 TFlops of data, which is fairly respectable, but much lower than today’s home consoles. The Steam Deck is capable of 720p gaming fairly seamlessly on low-to-medium settings on the go and is also built on the AMD platform.

AMD-equipped Teslas, including the Model 3 and Model Y, are packing an older Zen+ (Zen 1.5) APU (processor with a combined CPU and GPU). AMD claims that the V1000 - the same embedded chip as on AMD Tesla vehicles (YE1807C3T4MFB), brings up to 3.6 TFLops of processing power with it, including 4K encoding and decoding with the integrated GPU on board.

While that’s not enough for 4K gaming or comparable to a full-blown console or desktop GPU, that’s enough raw horsepower for light gaming and is currently more powerful than the Steam Deck.

The Model S and Model X’s GPU brings that up to about 10TFlops of power - comparable to modern consoles like the Xbox Series X at 12 TFlops.

Steam Gaming for All Vehicles?

The fact that Tesla is updating SteamOS even though the feature is no longer available in any new vehicles could indicate that Tesla is not only bringing Steam back to Teslas but that it’s going to play a much bigger role.

While SteamOS is run in a virtual environment on top of Tesla’s own OS, we could see Tesla bring SteamOS to all of its current vehicles, including the Model 3, Model Y, and Cybertruck. Steam in these vehicles would likely support any game that’s capable of running on the Steam Deck.

We think this Steam update, which includes performance improvements and a variety of fixes, has quietly passed under most people’s radars. This could be a very exciting update for those who enjoy gaming, especially for those who love to do it in their Tesla.

Tesla Holiday Update Weather Features: All the Small Details

Robert Rosenfeld / YouTube

As part of Tesla’s 2024 Holiday Update, Tesla included two awesome new features - Weather at Destination and the long-awaited Weather Radar Overlay. These two features are big upgrades built upon the weather feature that was added in update 2024.26. The original weather feature added an hourly forecast, as well as the chance of precipitation, UV index, Air Quality Index, and other data.

However, this update also added some smaller weather touches, such as the vehicle alerting you if the weather at the destination will be drastically different from the current weather.

Not a Tesla App

Weather At Destination

When you’re navigating to a destination and viewing the full navigation direction list, the text under the arrival time will show you the expected weather next to your destination. You can also tap this, and the full weather pop-up will show up, showing your destination's full set of weather information.

Note the weather under the arrival time

You can also tap the weather icon at the top of the interface at any time and tap Destination to switch between the weather at your current location and the weather at your destination.

You’re probably considering that the weather at your destination doesn’t matter when you’re three hours away - but that’s all taken into account by the trip planner. It will add in both charge time and travel time and show you the weather at your destination at your expected arrival time.

And if the weather is drastically different or inclement, such as rain or snow, while you’ve got sunshine and rainbows - the weather will be shown above the destination ETA for a few moments before it tucks itself away.

Tesla also recently introduced a new voice command. Asking, “What’s the weather?” or something similar will now bring up Tesla’s weather popup.

One limitation, though—if you’re planning a long road trip that is more than a day of driving, the weather at destination feature won’t be available until you get closer.

Weather Radar Overlay

As part of the improvements to weather, Tesla has also added a radar overlay for precipitation. You can access the new radar overlay by tapping the map and then tapping the weather icon on the right side of the map. It’ll bring up a radar overlay centered on your vehicle. It’ll animate through the radar data over the last 3 hours so that you can see the direction of the storm, but you can also pause it at any point.

You’re able to scroll around in this view and see the weather anywhere, even if you zoom out. It also works while you’re driving, although it can be a little confusing if you’re trying to pay attention to the navigation system. If you like to have Points of Interest enabled on your map, the weather overlay will hide POIs except for Charging POIs.

Requirements / Data

Unfortunately, you’ll need Premium Connectivity for any of the weather features to work, and being on WiFi or using a hotspot will not be enough to get the data to show up. The data, including the weather radar, is provided by The Weather Channel.

As for supported models, weather and weather at destination are available on all vehicles except for the 2012-2020 Model S and Model X. The weather radar has more strict requirements and requires the newer AMD Ryzen-powered infotainment center available on the 2021+ Model S and Model X and more recent Model 3 and Model Y vehicles.
