Tesla Patents Robotaxi Sanitization System - Reveals How It Will Work
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.
