A recently published Tesla patent application 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. Rather than risking delays in driving responses that result from input data errors, a signal is sent to ignore the bad information and continue processing as usual. Tesla’s application was published May 23, 2019 as International Publication No. WO/2019/099941.

During self-driving operations in Tesla’s program, streams of real-time input data are received and used to both train its neural network and initiate a vehicle response to what’s being processed. If something in the data is erroneous or causes a delay in processing, the real-world impact can be disastrous if not handled properly. For example, in a fast-moving vehicle, sensor data can become stale very quickly and cause the self-driving software to respond to an environment that no longer exists. This can result in accidents, property damage, injury, and/or death. The solution presented in Tesla’s patent application attempts to avoid such processing delays altogether and thus improves the safety of the self-driving software overall.

Tesla’s patent application describes the issue as follows:

“Some types of errors may cause neural network processor to hang or time out. That is, one or more portions of neural network processor may freeze or otherwise remain inactive for more than a predetermined amount of time. When a timeout error is encountered, [the] neural network processor may cease to provide output data and/or respond to input data. Other types of errors, such as program errors and/or data errors, may cause the output data generated by [the] neural network processor to be corrupted. When such errors are encountered, [the] neural network processor may continue to provide output data, but the result may be incorrect, meaningless, and/or otherwise unusable.”

On its face, the concept behind invention may seem somewhat simple, but likely due to the complexity of neural networks and the field of autonomous driving still being fairly new, Tesla’s solution is unique and innovative. At the international review stage in the patent application process, the Examiner found that Tesla’s patent was novel (new) compared to similar neural network inventions already in the field. Specifically, the following was commented in a Written Opinion:

“Although neural network processors are well known in the art, including in the operation of a vehicle, the addition of having the controller signal that a pending data result is tainted, or incorrect, without terminating the execution of the network, improves upon prior art processors by ensuring the computations of the processor in the vehicle continue while ignoring data determined to be in error, and would require a complexity beyond the ordinary skill, and therefore…meets the…criteria for patentability.”

Concerns about Tesla’s Autopilot software were recently hit by a report published by Consumer Reports wherein the consumer advocacy group concluded that Navigate on Autopilot with autonomic lane changes was more of a liability than an asset. The report stated that, since the feature requires drivers to be one step ahead of the system while it is engaged, it still needs improvement, although the same group found Tesla’s autonomous driving software to be more capable than the competition. However, the report was only focused on how Navigate on Autopilot operates when changing lanes confirmation and warnings are disabled, contrary to scathing headlines which lumped all of Autopilot’s features together with the review.

This most recent patent application shows that Tesla is continuously improving its self-driving features, if that wasn’t already obvious from the company’s frequent over-the-air software releases.

At Tesla’s Autonomy Day for investors last month, CEO Elon Musk declared that the company’s Full Self-Driving computer was objectively the “best in the world”. As more information becomes available, such as presentations on Tesla’s technology and in patent applications, Musk’s confidence expressed in his statement becomes more clear. Full Self-Driving is expected to be feature-complete this year and will become publicly available as regulatory hurdles are overcome.

Norway’s $2 trillion sovereign wealth fund votes against Elon Musk’s 2025 performance award

The fund is managed by Norges Bank Investment Management (NBIM), and it holds a 1.14% stake in Tesla valued at about $11.6 billion.

Norway’s $2 trillion sovereign wealth fund has voted against Elon Musk’s 2025 performance award, which will be ultimately decided at Tesla’s upcoming annual shareholder meeting. 

The fund is managed by Norges Bank Investment Management (NBIM), and it holds a 1.14% stake in Tesla valued at about $11.6 billion.

NBIM’s opposition

NBIM confirmed it had already cast its vote against Musk’s pay package, citing concerns over its total size, dilution, and lack of mitigation of key person risk, as noted in a CNBC report. The fund acknowledged Musk’s leadership of the EV maker, and it stated that it will continue to seek dialogue with Tesla about its concerns. 

“While we appreciate the significant value created under Mr. Musk’s visionary role, we are concerned about the total size of the award, dilution, and lack of mitigation of key person risk- consistent with our views on executive compensation. We will continue to seek constructive dialogue with Tesla on this and other topics,” NBIM noted.

The upcoming Tesla annual shareholder meeting will decide whether Musk should receive his proposed 2025 performance award, which would grant him large stock options over the next decade if Tesla hits several ambitious milestones, such as a market cap of $8.5 trillion. The 2025 performance award will also increase Musk’s stake in Tesla to 25%.

Elon Musk and NBIM

Elon Musk’s proposed 2025 CEO performance award has proven polarizing, with large investors split on whether the executive should be given a pay package that, if fully completed, would make him a trillionaire. 

Institutional Shareholder Services and Glass Lewis have recommended that shareholders vote against the deal, and initiatives such as the “Take Back Tesla” campaign have rallied investors to oppose the proposed performance award. On the other hand, other large investors such as ARK Invest and the State Board of Administration of Florida (SBA) have urged shareholders to approve the compensation plan. 

Interestingly enough, this is not the first time that Musk and NBIM have found themselves on opposing sides. Last year, NBIM voted against reinstating Musk’s 2018 performance award, which had already been fully accomplished but was rescinded by a Delaware judge.

Later reports shared text messages between Musk and NBIM Chief Executive Nicolai Tangen, who was inviting the CEO to a dinner in Oslo. Musk declined the invitation, writing, “When I ask you for a favor, which I very rarely do, and you decline, then you should not ask me for one until you’ve done something to make amends. Friends are as friends do.”

Tesla begins production of new Model Y trim at Giga Berlin

Tesla announced on Monday that its Model Y Standard configuration was officially being built at Giga Berlin, less than one month after the company officially announced the configuration early last month.

Tesla has begun production of the new Model Y trim at Gigafactory Berlin, the company’s production plant in Germany.

Tesla announced on Monday that its Model Y Standard configuration was officially being built at Giga Berlin, less than one month after the company officially announced the configuration early last month.

On October 7, Tesla announced the launch of the Model 3 and Model Y Standard trim levels, its answer to the call for affordable EVs within its lineup and its response to the loss of the $7,500 electric vehicle tax credit.

On October 3, Tesla started production of the vehicles in Germany:

The Standard iteration of the Model Y is void of many of the more premium features that are available in the Rear-Wheel-Drive, All-Wheel-Drive, and Performance trims of the vehicle are equipped with.

A few of the features of the Model Y Standard are:

  • Single Motor configuration
  • No rear touchscreen
  • Textile seats with vegan leather, instead of all vegan leather
  • 320-mile range
  • No glass roof

The launch of the Model Y Standard was truly a move to help Tesla get vehicles into the sub-$40,000 price point, and although many consumers were hoping to see the company get closer to $30,000 with these cars, this is a great starting point.

Deliveries in the United States have already started, and it seems it will be a vehicle that will do one of two things: either push some consumers to finally make the jump to Tesla, or it will give car buyers another reason to buy the Premium trims, as they may feel the lack of features is not a good enough deal.

This is something we saw with the Cybertruck’s Rear-Wheel-Drive configuration, which launched last year and ended up being more of the latter option listed above.

The Tesla Model Y Standard is actually a great deal in Europe

It was only a $10,000 discount from the All-Wheel-Drive Cybertruck, but it also did not have adaptive air suspension, premium interiors, or the powered tonneau cover, which many people felt was too much of a sacrifice.

The Rear-Wheel-Drive Cybertruck was discontinued only a few months later.

It does not seem as if this is the case with the Model Y Standard, which already seems to be an attractive option to some buyers.

Tesla has officially begun the wide rollout of Full Self-Driving (Supervised) v14 to the Cybertruck about a month after the company started rolling it out to other vehicles in the fleet.

On Monday, Tesla officially started rolling out v14.1.5 to Cybertruck owners, the first FSD v14 rollout for owners of the all-electric pickup.

Owners have been anxiously waiting for Tesla to begin the wide release of v14 to Cybertruck, as the company said it would refine the suite for the vehicle.

Tesla has finally started rolling out to many owners, who are reporting that their Cybertrucks are downloading Software Update 2025.38.8.5, which contains FSD v14.1.5:

Tesla has to be more cautious with rolling out FSD on the Cybertruck than on other vehicles for a few reasons. Initially, the Cybertruck utilizes an all-wheel steering system that turns differently than the S3XY lineup. This creates a challenge for the Tesla AI team as they have to cater to this specific maneuvering change.

Additionally, the Cybertruck is much larger, and the exterior cameras responsible for seeing the vehicle’s surroundings are placed differently than those of the other vehicles.

This requires additional calibration to ensure safety.

The full release notes for Full Self-Driving v14.1.5 are as follows:

  • Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, in a Parking Garage, or at the Curbside.
  • Added handling to pull over or yield for emergency vehicles (e.g. police cars, fire trucks, ambulances).
  • Added navigation and routing into the vision-based neural network for real-time handling of blocked roads and detours.
  • Added additional Speed Profile to further customize driving style preference.
  • Improved handling for static and dynamic gates.
  • Improved offsetting for road debris (e.g. tires, tree branches, boxes).
  • Improve handling of several scenarios including: unprotected turns, lane changes, vehicle cut-ins, and school buses.
  • Improved FSD’s ability to manage system faults and recover smoothly from degraded operation for enhanced reliability.
  • Added alerting for residue build-up on interior windshield that may impact front camera visibility. If affected, visit Service for cleaning!
