Tesla patent reveals ‘High Speed Wiring’ design for full self-driving safety

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

Conventional computer wiring programs don’t have any redundancy within their communications. Individual devices are attached to a central purpose (such as a chip ), and each device receives communications separately from that point via some type of cable. If a lot of the connections fails, communications into the device fails, and also in a situation, that might imply system collapse.

Simply adding backup cables isn’t really a solution. Cables imply connection issues, and should you worked with microcontrollers or circuit boards professionally or as a hobby, you are already able to find the disadvantage. More link points imply boards, and boards imply higher production expenses.

This is really where Tesla’s new wiring strategy comes in, which had been published on August 15, 2019 since US Patent Publication No. 2019/0248310.

The wiring structure, as described, includes a bi-directional backbone cable which forms a loop to and in the processor; together that backbone are all attached apparatus (i.e., segments) with hubs inside associated with a couple of cameras and/or radars. The backbone may function if one portion of the backbone fails meaning, data from hubs and all of the devices may nevertheless be delivered to and from the processor as a result of this dual-loop capacity.

A good way is to envision bumper cars or even a marble travel at a loop unimpeded. When there was a barrier to be trashed, marble and the vehicle could bulge against the barrier and travel in the opposite direction. Or, instead of a barrier to bulge, imagine a sharp U-turn came up, pushing the travel back in the other direction. The U-turn would happen on each side of the obstruction, meaning motion (communication) would nevertheless return and forth to the processor despite a rest in the larger loop (back ).

The particular advantage of this new structure over conventional systems, besides less cables connected to the processor, is that each hub within the apparatus can also be attached in serial or in parallel to the other hubs via the backbone. If a single hub within a device fails, the hubs may still transmit into the processor and into the backbone. In a conventional system, if a single cable to/from a device fails, then all of communications to/from radars and cameras in the device fails.

What Tesla’s performed this is mitigate the damage of a single entity failing within an FSD system to just that one thing. Here’s the way the program sums up this theory: “In embodiments, when backbone is formed using a bi-directional cable…subsequently the wiring system structure can tolerate one error at the backbone whilst still preserving communication pathways for all hubs and apparatus. ”

Especially, Tesla’s patent program also specifies that its technologies could be utilized in an assortment of vehicles, such as semi-trucks, indicating the business might intend to use the structure as a typical setup for all its FSD applications in the future. Language is included to expand the structure ’s program for farming, climatic, and industrial uses.

A couple of Tesla’s patent applications have shown numerous attempts being made to improve the safety of FSD systems opportunities for advancement are located. As an example, an application published in May branded “System and Method for Handling Errors in a Vehicle Neural Network Processor” refers to a method to safely manage errors encountered in self-driving applications. Another program titled “Autonomous Driving System Emergency Signaling” refers to a process of quickly communicating emergency data in vehicle detectors feeding to autonomous driving applications. While Full Self-Driving might have a significant quantity of time to become fully implemented for many different motives, there’s no wonder that Tesla is working hard to make it a reality.
