LNG: TESLARATI

There are probably very few companies in the market that have attracted the same amount of skepticism as Tesla. Since it started producing its first vehicle, the original Tesla Roadster, more than a decade ago, the “impending” death of the company has been foretold. Despite this, the small, disruptive electric car maker has stubbornly refused to die, and it continues to grow despite the noise. Today, Tesla is bigger than ever before, and the impending completion of a third Gigafactory 3 in China could signal yet another period of incredible growth for the company.

The inevitable electric age

The rise of Tesla did not only prove that electric cars need not be boring, glorified golf carts. The rise of Tesla also showed that consumers from various walks of life are willing to pay top dollar for well-designed electric vehicles, simply because they are superior to internal combustion cars. By proving these points, Tesla was able to force the hand of veteran automakers, pushing them to come up with their own battery-powered vehicles. Today, most of the world’s most notable carmakers are looking into electrification. Some brands such as Porsche have even decided to abandon diesel altogether, aiming instead to push the development of both all-electric and hybrid cars.

It’s not just Porsche either. Other automakers such as Jaguar even beat the German automaker’s Taycan to market with its I-PACE, which it started delivering last year. Daimler rushed to join the fray with the EQC, and Audi, not to be left behind in the emerging EV race, brought out the rather unfortunately-named e-tron, which was received warmly nonetheless. Even mass-market automakers such as Kia and Hyundai have come up with their own bang-for-your-buck electric cars in the form of the Niro EV and Kona Electric. Volkswagen recently made a splash with the debut of the ID.3 as well. Even British-bred MG, which has been reborn as a Chinese-owned hyper-budget brand, is preparing to attack the lower end of the market with the MG ZS EV.

Learning from Tesla

Amidst this transition, it is starting to become evident which carmakers are dead serious about their transition to the electric age. This became notable in Germany, when Volkswagen, Daimler, and BMW came together last March to call for the widespread adoption of EVs. Volkswagen CEO Herbert Diess was at the helm of the radical stance, at one point practically butting heads with BMW CEO Harald Krüger and the industry lobby group Association of the Automotive Industry (VDA) due to his push for widespread electric car adoption. Audi boss Bran Schot, in a recent interview with Manager Magazin, reiterated this point, noting that “electric is the core” of the automaker’s “new strategy.”

Audi is currently attempting to ramp the production of the e-tron SUV, its first all-electric vehicle, but things have not exactly been easy. Due to factors such as reported battery constraints from supplier LG Chem, as well as other incidents such as a workers’ strike in one of its plants earlier this year, the e-tron has been delayed. Yet, Schot noted that the company remains focused on pushing more electric cars. During the interview, Schot candidly admitted that Audi is behind other automakers such as Tesla, not only “in the electric cars” themselves, “but also at the pace with which they solve some software issues.”

Schot noted that he was recently “driven once again a Tesla,” and he came away impressed by the experience. “That was fun,” he said, later admitting that “No question, we are learning from Tesla.” Learning from the leader in electric mobility is an excellent strategy for Audi, as it would allow the company to develop vehicles that mix the best of veteran auto’s experience and Tesla’s tech mastery. In a way, Audi has already taken steps towards this goal with its e-tron GT sedan, a vehicle built on the same platform as the Porsche Taycan. The Taycan stands apart from other EVs from veteran auto in the way that it’s built from the ground up to be an electric car, making it the last thing from a compliance vehicle.

Commitments to diesel and a denial of EVs

While companies like Porsche have found it easy to commit to electrification and abandon things like diesel, other carmakers are not having such an easy time relinquishing their ties with oil. The most recent source of this shock was Jaguar Land Rover CEO Ralf Speth, who recently spoke with Automotive News Europe sister publication Automobilwoche’s publisher in an interview. When asked about the company’s powertrain strategy amid a decline in demand for diesels and V8 gasoline engines, the CEO was candid.

“According to industry forecasters, a global share of 20 percent to 30 percent for electrified vehicles is expected by 2025. When you turn this around, it means that 70 percent to 80 percent of all vehicles around the world will have conventional engines. Let me add that today’s diesels, (which) are absolutely CO2-efficient and clean,” he said.

When asked by the publication why electric mobility is still not important to consumers, the CEO noted that “On one hand, the products are still too expensive. On the other hand, the infrastructure is still too inconvenient and unreliable, so electric cars tend to be for people with deep pockets.” These are rather surprising to hear from the Speth, whose company produced the I-PACE, which has pretty much swept awards left and right since its debut last year.

Explaining his conservative stance on electric vehicles further, the Jaguar CEO argued that “When it comes to electric vehicles, the question isn’t how many cars I can build but rather how many batteries I can buy. The demand for batteries is so great that there will be a limited ability to deliver them over the next few years. And, unlike some others, I expect continually rising battery prices – at least for the next two to three years.”

Quite interestingly, the Jaguar Land Rover CEO’s concerns about electric cars have long been addressed by Tesla. When it came to charging infrastructure, the California-based carmaker developed and aggressively rolled out its Supercharger Network, which currently have over 12,000 stations across the globe. The company has also ironed out the supply of its vehicles’ batteries, thanks to a massive investment in facilities such as Gigafactory 1 in Nevada.

The transition to the electric age will be difficult for carmakers, and it would require massive investments just to get well-designed all-electric cars ready for the market. If these developments are any indication, it appears that in the next few years, the battle lines will be drawn between veteran automakers that are willing to go all-in on electric mobility, and veteran carmakers who will steadfastly hold on to oil and the internal combustion engine.

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.

The Tesla Model 3 recently took on the Moose Test, a challenging test that simulates what happens to a vehicle when it swerves sharply to avoid an obstacle in the middle of the road. According to auto publication Km77.com, which conducted the test, the Model 3 not only passed the evasive maneuver test; it did so in a very impressive, commanding manner.

The Moose Test is performed on a dry road surface, with traffic cones set up in an S-shape to simulate an obstacle. Vehicles drive on the track, then quickly swerve into the “oncoming lane” to avoid the “obstacle,” before swerving back to avoid oncoming traffic.

The test is conducted at several speeds, in order to determine how well a vehicle would evade a potential collision on the road. The test is repeated in increasing speeds until the vehicle skids, knocks down cones, or spins out. On average, these usually happen at speeds of about 70-80 kph (45-50 mph).

The Tesla Model 3 performed incredibly well in the auto publication’s evasive maneuver tests. Multiple drivers went behind the wheel of the electric sedan, and each one came away impressed at the way the Model 3 handled itself on the course. The Model 3 actually ended up setting a record among the numerous vehicles that have been tested by Km77.com, achieving an entrance speed record of 83 km/h (51.5 mph). Footage of the vehicle show the Model 3 performing incredibly well despite the higher speed.

A key factor that played a significant role in the Tesla Model 3’s stellar Moose Test results was the electric sedan’s regenerative braking system. The auto publication’s drivers noted that it was quite easy to decelerate and control the Model 3’s speed due to regenerative braking. This feature played a role in the Model 3’s record-setting 83 km/h Moose Test, which involved the publication setting regen to Standard. Km77.com‘s test drivers noted that a Low regenerative braking setting still allowed the Model 3 to perform fairly, though the vehicle did not react as well as it did when the feature was set to Standard.

Another factor that contributed to the Model 3’s stellar Moose Test results was the vehicle’s all-electric design. Steering was quick and responsive, especially for a rather heavy sedan, and thanks to its floor-mounted battery pack, the Model 3’s center of gravity is quite very low, giving almost no body roll to the vehicle. This allowed the Model 3 to be in control during the Moose Test’s sharp maneuvers.
