The "unstoppable" Tesla Model 3 seems to have faded out of people's vision for a long time, and the "brake door" incident has basically stopped. However, the recent strong return of the Tesla Model 3 has changed from a "brake door" to a "stall door". This time Tesla did not pull anything, but directly admitted its mistakes, and from April 7, it carried out a large number of recalls.
Let Tesla admit that the owner of the Model 3 mentioned on New Year's Day, there have been some small problems, usually in the process of using the car, there will be a sound of current on the car for no reason, after locking the car, it will run, the car will make a rumbling sound, reopen the door and close it again, there will be no care.
The "brake door" was extinguished, and the new "door" quietly arrived
At the time of the incident, he drove at a speed of 100 kilometers in the tunnel normally, suddenly without warning, the screen showed "the vehicle can not continue to drive, please stop immediately", because there is a car following behind, the driver stepped on the electric door deeply, but the car did not respond. The owner immediately double flashed, and changed two lanes in a row, and finally stopped in the emergency lane.
The car was pulled to the Tess aftermarket processing center, and Tesla's initial communication said that the fault code pointed to the inverter. Subsequently, on the afternoon of April 7, Tesla filed a recall plan with the State Administration for Market Regulation in accordance with the relevant national laws. Unlike some car companies that have increased emulsification of long-term oil and seriously burned oil, Tesla's recall speed can be described as "divine speed".
But it's a bit confusing to see the solution: Since April 7, Tesla will recall a total of 127785 imported and domestic Model 3 models. There may be minor manufacturing differences in the rear motor inverter power semiconductor components of the vehicles within the scope of this recall, which may malfunction, causing the vehicle to stall, and there is a safety hazard. Tesla said that it will upgrade the motor control software for the vehicles within the scope of the recall through the remote upgrade of the car OTA technology; for the vehicles that cannot be recalled through the remote OTA upgrade technology of the car, the motor control software will be upgraded for the vehicle, and the rear inverter of the relevant failure will be replaced for free in time to eliminate the safety hazard.
Obviously said that the parts have differences in manufacturing process, but to give some models have OTA to upgrade to solve, hardware defects with a few lines of code of software to solve, the last one to do so is Boeing 737-Max, the height of the aircraft is too low, the center of gravity is problematic, with software to control the aircraft's leveling angle and center of gravity position, until 346 lives fall... Since there is a problem with the manufacturing process, it should be changed, and it should be repaired, and it should not be left with the space for the public's imagination on this issue.
All along, Tesla makes everyone the most uneasy, one is that it can't brake the car, one is the problem of its so-called automatic driving system "FSD", this part has received special attention, there is an important reason why it needs to spend another high price to buy separately, and the poor experience after opening will cause the owner's overreaction: spending so much money, you got this thing, you also take me as a test product.
Domestic and foreign leeks "distinguish" from cutting
In a dispute case in Germany on March 29, 2022, the court ruled that Tesla needed to buy back the Model 3 from this owner, Tesla needed to refund 69,000 euros (about 490,000 yuan) to the owner, and when the owner purchased the Model 3, he spent 6,300 euros to buy the FSD fully autonomous driving kit, the German owner believes that the Autopilot autopilot assist system is not as advertised, and he also purchased a higher-level FSD fully automatic assisted driving. The owner pointed out that the FSD assist function cannot be activated by automatically exceeding the slow car on the highway, the traffic sign and stop sign cannot be accurately recognized, and the turn is like "a drunk novice driving a car" at the intersection of the highway entrance and exit. At present, Tesla has appealed the judgment, Tesla still adheres to its usual style, this car is not flawed, the future will update the software features, but do not know the specific day ...
This is a rare court judgment Tesla to return the car case, the last time should be Tesla sold to Mr. Han accident car in Tianjin, Beijing Daxing Court ruled that Tesla returned one to pay three, Tesla finally really compensated Mr. Han more than one million, but the backhand sued Mr. Han for infringing Tesla's right to reputation, compensation of more than five million ... This wave can be described as "basic exercise 6", I believe that Tesla's legal department, even if it is really a problem, lose money to pay you back, will let you double to find a make-up.
Is it caused by the "core changing door"?
Although it is not clear why the Model 3's FSD does not work properly, there are many people speculating that this should be related to the chip shortage, because Musk promised on April 22, 2019, that all owners with optional FSDs will be equipped with HW 3.0, the problem is that in the past two years, many customers have continuously received cars with HW 2.5, and Chinese consumers have been treated this way in early 2020. HW3.0 has the computing power needed for autonomous driving, while the Model 3 of German owners may be equipped with the old HW 2.5, resulting in the function not working properly.
We know that the data obtained by these sensing components in high-speed vehicles is very large, so it requires a processor with strong computing power to process data and send instructions, HW2.5 is Avidia's processing chip specially developed for Tesla. The HW3.0 chip is the latest chip developed by Tesla itself, Musk introduced at the press conference of this chip that the performance of HW3.0 is 21 times that of HW2.5, and also has an independent safety module assist, even if one of the modules has a problem, the car can still drive normally, and it is better in safety. In terms of function, HW3.0 is to achieve full automatic driving of FSD, such as identifying pile barrels, traffic lights, etc. are all available in HW3.0.
If there is a ready-made one, why do you need to study it yourself?
There are 4681 components on the board of the HW2.5, compared to the 4746 components of the HW3.0, Tesla is crammed with more components in the same area of the board. For HW3.0, the number of processors was reduced from 4 Tesla SOCs to 2. The technology node used in the HW3 is 14nm, while NVIDIA's HW2.5 processor is 16nm. When HW3.0 was introduced, it was the first time the 14nm process had been used in a car. ”
But is it really worth spending a lot of R&D money and designing your own integrated circuit chips just for your own model, and maybe it won't be available? Is it bad to continue to buy NVIDIA's "new work"?
In fact, the automotive industry rarely sees any automaker designing integrated circuit chips for their own cars in-house. This is a big risk, unless the technology is strong and the money is strong, considering today's automotive market, it is not a simple matter of making a decision on the head. However, Tesla is not alone, and there are many automotive OEMs that are eager to develop their own Autopilot processors like Tesla.
Over the past few years, as more and more electronic components have entered the automotive market, many automotive OEMs have learned that leading chip suppliers like Nvidia and Intel are accustomed to maintaining huge profit margins for their SOCs, CPUs and GPUs, and that there is very little room for car companies to bargain. If OEMs don't want to continue to negotiate prices with chip suppliers for the next five years, they may find it easier to develop their own SOCs to control their own destiny.
Tesla's HW2.5 consists of three Nvidia chips and an Infineon MCU and costs $280. By comparison, Tesla's HW3.0 is based on Tesla's two SOCs, which sell for $190 and cost a significant drop.
Tesla chip developers point out that assuming a car manufacturer spends $150 million on its own processor design costs, and the part pricing and annual production of 400,000 units don't change, "our quick estimates show that you can recoup your investment in 4 years." ”
The "futures function" is indeed time to manage
Speaking of the fact that the actual functions of the FSD are not in line with the advertised situation, tesla FSDs have been on sale for more than 6 years, but at present only some owners in the United States and Canada can use most of its functions. For other vehicles, FSD is a futures, and practical functions are almost equivalent to enhanced driver assistance systems (EAPs). Musk also said that a full version of the FSD will be launched in Europe, and the launch time depends on local regulations.
The decision of the Darmstadt District Court in Germany sets a precedent for such cases in Germany in the future, and we have no doubt that it will have legal implications for autonomous vehicles worldwide. Although Germany passed the draft Autonomous Driving Law, Germany also became the first country in the world to allow driverless vehicles (L4 level) to participate in daily transportation and be applied nationwide. Starting in 2022, Germany will allow specific vehicles (shuttles, buses, vans, etc.) for autonomous driving on public roads, paving the way for large-scale deployment of robo-taxis and delivery services in the country.
However, Tesla's current so-called automatic driving is not covered by this law, which also lays a certain foundation for Tesla's future appeals, for Tesla, this is a battle that must not be lost.
The basic exercise of the new forces will be risky to go to sea
This has also sounded the alarm for car companies around the world that have been flaunting autonomous driving, especially the new forces of the mainland car manufacturers, for the Xiaopeng that has gone to sea, it is more necessary to pay attention to, and your various publicity may not be able to rely on the current law in the field of automatic driving that is relatively vacuum in the mainland, and even if there is a problem, there is no way to punish or rectify. But for those countries that already have complete legislation, and even from the previous laws can "put you to death", this is very important to pay attention to, and the functions that are not available or cannot be realized for the time being cannot be promised prematurely.
At present, the domestic new forces are engaged in this set of "futures function" play, the vehicle is in a "semi-finished product" state when the car is delivered, and the later stage needs a continuous OTA to achieve the function, domestic consumers swallow their voices, see that it is not easy to list financing in your listing, do not care about the end, foreign consumers do not have this patience, nor these national feelings, I paid you the money for the complete function, but you gave me the realization in batches and installments, and the time span of each batch is extremely large. Tesla this time is good that there are still these functions, but it is not easy to use, resulting in car owners not buying, and the current new force models are not functionally difficult to use, but directly when they are bought, it is really possible to be sanctioned overseas, and the general penalty will be more cruel.
Next, we will continue to pay attention to the follow-up situation of Tesla's incident, to see what kind of "god operation" Tesla's legal department will make, I estimate that even if it is really Tesla's own problem, it will not lose money, give up, and after lying down, it will suddenly sit up and bite the owner, the domestic Tesla will cut us as leeks, and foreign leeks will not be fragrant?
