According to foreign media BGR news reports, a video shared by individuals showed that a self-driving Tesla Model 3 was suspected to have hit a truck on the side of the road while driving on the highway in Taiwan Province province, China last weekend. However, this is not the first time. As early as a few years ago, the final result of Tesla's fatal car accident in the United States was that the autopilot sensor could not identify the white truck from the surrounding bright sky. The accident happened in Taiwan Province province, because the driver and sensor didn't find obstacles, which led to the accident!
However, according to the current development of autonomous driving, this is already the most mature solution in the world. The advantage of Tesla is that nearly one million cars can continuously transmit data, thus improving the judgment cases and data accumulation of the machine, which is impossible for other platforms such as Google Baidu.
Judging from the current mainstream concepts, the level of autonomous driving can be divided into L0-L5 levels.
L0 level means that there is no automation technology, and the driving of the vehicle depends entirely on the manual operation of the driver.
L 1 driver assistance is actually very common. Many domestic 65,438+10,000 cars will also have the function of cruise control and parking, but the driver's hands can't leave the steering wheel!
L2 level is the highest level of assisted driving at present, including high-speed automatic assisted driving, automatic assisted driving in congestion, automatic parking and automatic danger warning braking. In some cases, the driver can even leave the steering wheel for a short time.
L3 level is conditional automation. At this level, the driver can hand over the power of the throttle brake, but he can't divert his attention. He needs to observe and intervene manually at any time and can't completely lose the steering wheel. Can only say that this is an embarrassing level, and even makes the driver more tired!
L4 is highly automated. At this level, the driver can completely let go of the steering wheel, and the power to throttle and brake is also given to the machine, and other things can be handled by himself. In other words, the machine can almost completely replace the driver!
L5 is the ideal level, fully automatic. During the whole driving process, the driver does not need to assist in observation and judgment. In all complicated situations, the machine will judge for itself, and the user can do anything in this process!
In fact, judging from the current development of the automobile industry, L3 has become very popular in some high-end models, and even becomes standard in the field of electric vehicles, which makes us have abnormal expectations for automatic driving above L4 level. Once the L4 automatic driving is gradually popularized, it is likely to have a revolutionary impact on the current driving-related industry laws and regulations, and even the driving test will soon disappear!
However, Tesla's example tells us that fully automatic driving above L4 level is really not that simple. The accident proves that there are still problems with Tesla's solution. For example, in radar, if you switch to more expensive radar technology, you can effectively avoid previous accidents. On the other hand, this will undoubtedly increase the cost of Tesla, so that its price has to be increased too much, leading to a decline in competitiveness.
Secondly, in the real driving scene, the road conditions change rapidly, which tests the driver's experience, psychological quality and ability to solve problems on the spot. This requires too much of the machine, so the machine can only judge the risk in real time, thus avoiding the risk. But in the event of an accident, can the machine respond?
After all, the reason why many countries ban autonomous driving on the road under the existing conditions is not that they don't support autonomous driving, but that once an accident occurs in autonomous driving, it is likely to cause car crashes and deaths, and we can't ignore the small probability!
At present, for users in China, the price of Tesla fully automatic driving bag has reached 56,000 yuan, which is close to one fifth of the car price. However, judging from the functions that can be used in China at present, the cost performance is not high. Even, this function is actually a kind of futures, which is somewhat similar to the concept of auction house. Tesla promises to deliver this function in the future, and we can't judge whether the R&D cost will decrease with the sharp increase in Tesla sales.
Most importantly, such technology can be carried out through OTA, and users don't need to worry about not getting such functions in the future!
