A recently published Tesla patent application titled “Autonomous Driving System Emergency Signaling” describes a method of quickly communicating emergency information from vehicle sensors feeding into autonomous driving software. The new communication method will improve Autopilot’s response in emergency situations, thereby reducing the probability of accidents.

Tesla’s invention takes latency in data transmission into account as an area of improvement. In general, critical information can get stuck waiting to be processed by a computer after non-critical information that’s ahead of it. Under Tesla’s US Patent Application No. 2019/0138018, critical emergency situations detected by sensors are moved to the front of the line for priority processing and response. Tesla’s invention achieves this using two main approaches.

First, the transmission from sensors that detect an emergency sends their findings to the main computer at a higher transmit power than other messages. Other signals at lower power transmissions are then interpreted as ‘background noise’ compared to the emergency signal. This process is described in the patent application as follows:

When an autonomous driving emergency event is detected by an autonomous driving sensor…the [sensor] transmits the autonomous driving emergency message in a non-assigned time slot at a higher transmit power level than a transmit power level of an autonomous driving sensor…Because the autonomous driving emergency message is transmitted at a higher power level than the transmission from the autonomous driving sensor, the transmission from the autonomous driving sensor may be treated as background noise by the autonomous driving controller to thereby receive and decode of the autonomous driving emergency message.

In a second approach, the autonomous driving sensors that encounter an emergency message are programmed to stop sending signals, and the vehicle’s main computer will direct them to resume communications after receiving the emergency message. This process is described in the patent as follows:

…if an emergency transmission is detected…the autonomous driving sensor ceases transmitting autonomous driving data. Such cessation may continue for one assigned time slot, for more than one assigned slots, and/or until the autonomous driving sensor receives direction from the autonomous driving controller to continue transmitting autonomous driving data or receives a new…bus time slot assignment from the autonomous driving controller. During this time period…the autonomous driving sensor continues to collect and buffer autonomous driving data.

Several variations of achieving these two main concepts are also described in the application and invention claims, including managing the specifics of the transmit power level differences and reassigning time slots for sensors to communicate on the data bus. Overall, this recent patent application is yet another indicator of Tesla’s continued improvement of its autonomous driving capabilities.

Tesla’s advances in the autonomous driving arena have been touted by CEO Elon Musk and industry experts alike. ARK Invest analyst James Wang recently estimated that the all-electric car maker’s decision to develop its Full Self-Driving computer chip in-house put the company four years ahead of the competition. Musk, for his part, declared the chip the best in the world at Tesla’s Investor Autonomy Day. “It seems improbable. How could it be that Tesla, who has never designed a chip before, would design the best chip in the world? But that is objectively what has occurred,” Elon touted.

While Tesla has yet to roll out the total capabilities of its Full Self-Driving suite, Musk has said on several occasions that the software will be “feature complete” by the end of 2019 with only regulatory hurdles left for full release.

Just days after unveiling the Xiaomi YU7, a vehicle that is considered as the Model Y’s strongest competitor yet, Xiaomi CEO Lei Jun gave a nod of respect to Tesla and its Full Self-Driving (FSD) program. 

In a post on Weibo, Lei Jun highlighted the remarkable nature of Tesla’s first autonomous delivery. He also acknowledged that Xiaomi still has much to learn in the electric vehicle industry.

Xiaomi CEO’s Nod of Respect

Lei Jun’s comments about Tesla’s FSD delivery were shared as a response to Tesla VP Grace Tao’s post about the recent feat. The Tesla VP shared several key aspects of the delivery, from the fact that there was no driver in the Model Y to the vehicle reaching over 70 mph as it drove to its owner. 

“For the first time in history, the vehicle was delivered to the owner by itself. There was no driver or remote control throughout the journey, and the maximum speed reached 115 kilometers per hour, and it arrived safely at the customer’s door. This is a brand new Model Y. Tesla always surpasses imagination with disruptive innovation. A new era, exciting!” Tao wrote in her post.

In his response, the Xiaomi CEO acknowledged Tesla’s incredible feat. “Tesla is indeed amazing, leading the industry trends in many areas, especially FSD. We still have to continue learning!” he wrote.

Xiaomi’s Recent Tesla Competitor

The Xiaomi CEO’s comments show that Tesla’s projects and leadership garner a lot of respect in the global electric vehicle sector. While Tesla and Elon Musk tend to be media punching bags in the United States and Europe, the company and its CEO seem to be taken very seriously in China. This was despite China being the world’s most competitive electric vehicle market.

Xiaomi itself has become one of Tesla’s strongest rivals in China, with its first car, the SU7, bringing the fight to the Tesla Model 3. Its most recent vehicle, the YU7, could very well be the Model Y’s most legitimate rival yet, as it is more affordable, bigger, and more feature-laden than Tesla’s best-selling crossover. The YU7 has garnered quite a lot of attention, with Xiaomi receiving 200,000 firm orders for the vehicle within the first three minutes of its launch.

Tesla silences FSD critics by posting full video of Model Y delivering itself to customer

When Elon Musk posted that the first Tesla had delivered itself to its owner, critics were quick to question his statement.

It is no secret that Tesla still has ardent critics today, many of whom remain convinced that the company and its leadership are lying about Full Self-Driving (FSD) and its capabilities. It was then no surprise that when Elon Musk announced that the first Tesla had successfully delivered itself to its owner, critics were quick to question the CEO’s statement.

Videos of the all-electric crossover’s solo drive to its owner soon silenced Tesla critics and their claims.

Tesla Posts FSD Video Proof—Twice

While Musk’s post on X about a Tesla delivering itself to a consumer was a notable update, his claims were not accompanied by any video. This was taken by some Tesla critics as a hint that the CEO’s claims were false, and that the feat probably did not happen. Musk, for his part, noted that Tesla would soon be posting a video of the self-driving car’s drive to its owner.

The electric vehicle community did not have to wait very long. Tesla later posted a video of its first autonomous vehicle delivery ever on X, much to the shock of social media users. As could be seen in the video, a Tesla Model Y was able to travel about 30 minutes on its own, from the end of Giga Texas’ production line to the home of its owner, several miles away. Tesla even posted the vehicle’s full 30-minute drive on its official X account later on. 

Critics Are Still Skeptical, But It’s Cope at this Point

Of course, Tesla skeptics remained unconvinced that the feat was legitimate, with some pointing out that the Model Y customer seems to have had an X account for years but never posted, at least until his car was delivered. Others also claimed that the whole setup seemed suspicious since the Model Y looked like it had manufacturer plates as it navigated Austin’s streets.

These concerns, however, do not seem like very strong arguments, especially at this point. Based on the evidence, it seems like Tesla really has figured out autonomous driving, and its cars are now able to operate safely on real-world roads on their own. Many have also become silent in their criticisms of Tesla’s FSD feat, especially after the company posted the full video of the Model Y’s autonomous drive. Overall, Tesla critics may remain doubtful about the company and Musk’s claims, but these concerns seem to have become forced at best.

Ford CEO Jim Farley shared some skepticism about Tesla’s camera-only approach to self-driving during a recent appearance at the Aspen Ideas Festival. When asked to compare Waymo and Tesla’s autonomous driving systems, Farley stated that Waymo’s LiDAR-based approach made “more sense,” citing safety, consumer trust, and the limitations of camera-based models.

Waymo’s LiDAR vs. Tesla’s Vision-Only Approach

Farley was speaking with author Walter Isaacson when he made his comments about Tesla and Waymo’s self-driving systems. As they were conversing about autonomous cars, Isaacson asked Farley which approach to self-driving he preferred.

“To us, Waymo,” Farley said, though he also stated that both Tesla and Waymo have “ made a lot of of progress” on self-driving, as noted in a Fortune report. He also confirmed that he has had conversations about the matter with Tesla CEO Elon Musk. Despite this, he said that Ford still considers LiDAR as a pivotal part of autonomous driving. 

“When you have a brand like Ford, when there’s a new technology, you have to be really careful. We really believe that LiDAR is mission critical… Where the camera will be completely blinded, the LiDAR system will see exactly what’s in front of you,” the Ford CEO stated. 

Tesla and Ford’s self-driving plans

Tesla recently launched a limited Robotaxi service in Austin, which uses autonomous cars with safety monitors in the front passenger seat. While controversial, Musk has maintained that Tesla’s vision-only approach will ultimately prove safer and more cost-effective in the long term. Tesla seems to be making headway towards this goal, with Musk stating recently that the first Model Y has been delivered autonomously to a customer in Austin.

Ford, for his part, is not pursuing its own fully autonomous, urban-driving system anymore. Instead, the company is focusing on “high-speed, eyes-off” experiences like BlueCruise. Ford does plan to partner with a company that has achieved true autonomous driving in the future, as soon as the technology is available.
