Tesla has filed a recently-published patent application titled “High-Speed Wiring System Architecture” that addresses an important aspect of its Full Self-Driving (FSD) suite: redundancy.

Traditional computer wiring systems often have no redundancy in their communications. Individual devices are connected to a central point (such as a processor), and each device receives communications separately from that point via some sort of cable. If one of the connections fails, communications to the device fails, and in a self-driving situation, that could mean complete system failure.

Simply adding more backup cables isn’t really a great solution, either. More wires mean more connection points, and if you’ve ever worked with microcontrollers or circuit boards professionally or as a hobby, you can already see the downside to this. More connection points mean bigger boards, and bigger boards mean higher manufacturing costs.

This is where Tesla’s new wiring system comes in, which was published on August 15, 2019 as US Patent Publication No. 2019/0248310.

The wiring architecture, as described, comprises a bi-directional backbone cable that forms a loop to and from a processor; along that backbone are connected devices (i.e., segments) with hubs inside associated with one or more cameras and/or radars. The backbone can function as two separate loops, meaning if one portion of the backbone fails, data from all the devices and hubs can still be sent to and from the processor thanks to the dual-loop capacity.

Perhaps a good way to visualize this is to imagine bumper cars or a marble traveling in a loop unimpeded. If a barrier were to suddenly be erected, the car and marble would bump the barrier and travel in the opposite direction. Or, instead of a barrier to bump, imagine a sharp U-turn came up, forcing the travel back in the other direction. The U-turn would happen on either side of the barrier, meaning motion (communication) would still continue back and forth to the processor despite a break in the larger loop (backbone).

The specific advantage of this new architecture over traditional systems, other than less cables connected to the processor, is that each hub within the devices is also connected in serial or in parallel to the other hubs via the backbone. If one hub within a device fails, the other hubs can still transmit to the backbone and thus to the processor. In a traditional system, if one cable to/from a device fails, all communications to/from radars and cameras inside the device fails.

Essentially, what Tesla’s done here is mitigate the damage of one thing failing in an FSD system to just that one thing. Here’s how the application sums up that concept: “In embodiments, when backbone is formed using a bi-directional cable…then the wiring system architecture can tolerate one fault in the backbone while still maintaining communication pathways for all hubs and devices.”

Notably, Tesla’s patent application also specifies that its technology could be used in a variety of vehicles, including semi-trucks, indicating the company may intend to use the architecture as a standard setup for all its FSD programs in the future. Additionally, language is included to broaden the architecture’s application to farming, nautical, and other industrial applications.

A few of Tesla’s recent patent applications have demonstrated numerous efforts being made to improve the safety of FSD systems wherever opportunities for improvement are found. For example, an application published in May titled “System and Method for Handling Errors in a Vehicle Neural Network Processor” describes a way to safely handle errors encountered in self-driving software. Another application titled “Autonomous Driving System Emergency Signaling” describes a method of quickly communicating emergency information from vehicle sensors feeding into autonomous driving software. While Full Self-Driving may take a significant amount of time to be fully implemented for a variety of reasons, there’s no question that Tesla is working hard to make it a reality.

Tesla Full Self-Driving’s European launch frustrations revealed by Elon Musk

Tesla plans to launch Full Self-Driving in Europe later this year, but regulatory bodies are proving to make it a bigger challenge than it needs to be.

Tesla Full Self-Driving is set to launch in Europe in the future, but the region’s governing bodies are not giving the suite any chance to move forward, according to CEO Elon Musk, who blames the regulatory processes for robbing citizens of a safer mode of travel.

The automaker revealed late last year that it planned to bring Full Self-Driving to Europe sometime in 2025. However, Musk said that the launch of the suite is being continuously prolonged by both individual and European Union officials, dragging their feet with approvals.

In a post on X on Wednesday, Musk said the company is still dealing with and waiting for approvals from both the Dutch government and the EU’s governing officials, giving an indication that some progress has been made, but ultimately, there are still some bodies that are taking their time:

He continued by stating that the delays are “very frustrating” and they “hurt the safety of people in Europe” because of Autopilot’s statistical prowess, which shows it is much safer than human drivers.

Tesla is readying for the launch of a completely driverless Robotaxi platform in the U.S., which is set to occur in the coming days. While the initial rollout of the platform will be reserved for a select few, public rides are slated for June 22, meaning anyone will be able to come to Austin and hail a Tesla Robotaxi through the company’s smartphone app.

The first Robotaxi without a driver was spotted in Austin yesterday and shared on X:

Musk dropped several hints that the Robotaxi launch, which has been rumored for June 12, is imminent. For now, the operation will take place in Austin and will eventually expand, likely to California next, as noted in past reports. The City’s official website confirmed that Tesla gained a license as an Autonomous Vehicle operator in the City of Austin earlier this week.

Tesla applied for a similar license in California earlier this year.

More Megafactories

The Lathrop Megafactory is Tesla’s first dedicated facility for its flagship battery storage system. It currently stands as the largest utility-scale battery factory in North America. The facility is capable of producing 10,000 Megapack batteries every year, equal to 40 GWh of clean energy storage.

Thanks to the success of the Megapack, Tesla has expanded its energy business by building and launching the Shanghai Megafactory, which is also expected to produce 40 GWh of energy storage per year. The ramp of the Shanghai Megafactory is quite impressive, with Tesla noting in its Q1 2025 Update Letter that the Shanghai Megafactory managed to produce over 100 Megapack batteries in the first quarter alone.

Tesla Energy’s Potential

During the first quarter earnings call, CEO Elon Musk stated that the Megapack is extremely valuable to the energy industry. 

“The Megapack enables utility companies to output far more total energy than would otherwise be the case… This is a massive unlock on total energy output of any given grid over the course of a year. And utility companies are beginning to realize this and are buying in our Megapacks at scale,” Musk said.
