The battle for intelligent driving is a messy one, but traditional car companies want to win with "stability".
Compared to purely electric drive, autonomous driving technology has a greater imagination, it changes not only the car, and can even change people's future lifestyle. At the moment, not only are new car makers willing to spend huge amounts of money and energy on self-driving technology, but many technology companies and travel companies also see self-driving as a technological high point for the future market, and they are more energized.
Among all the technologies that have been put into practice, Tesla's Autopilot is recognized as the best automatic driving function in a production car, which not only allows the vehicle to automatically assist in steering, accelerating, and braking in a lane according to the situation, but also allows it to automatically drive into and out of highway ramps and overpasses, and even automatically assist in changing lanes on the highway. The company's newest product is a new generation of the "Maserati".
Musk's confidence in his own technology has been overwhelming, and at the 2020 World Conference on Artificial Intelligence, Musk even boasted that Tesla is now very close to the L5 level of autopilot, and is confident that the development of the basic functions of the L5 level will be completed within the year. However, the fact is far from perfect as described by Musk, in 2016 and 2019, the United States occurred 2 Tesla and white truck collision accident, the accident even caused a death. 2020 June, Taiwan also occurred Model3 straight into the overturned white truck accident, and these accidents occurred when the Autopilot system are activated. In four years, the "best automatic driving function" has not been able to solve the recognition of the "white truck" this kind of seemingly simple problem, which will inevitably make people skeptical of the development of the future of automatic driving technology.
Compared to Musk, He Xiaopeng's understanding of automated driving is more rational, he will be divided into the L5 level of automated driving software development and technology landing two levels to see, that the development of technical level in the short term is feasible, but the technology landing at least 3-5 years. Ali AI Laboratory Chief Scientist Wang Gang has also expressed the same view in an exclusive interview with the media, he believes that the biggest difficulty in the landing of automatic driving is that the driving algorithms in many cases can not effectively deal with the complex traffic conditions on the road, the diversity of the scene is the biggest challenge facing the automatic driving.
In addition to technical bottlenecks, regulations are also a constraint on the landing of automated driving technology. Although some U.S. states, the European Union, Japan and other developed countries and regions have carried out relevant legislation on automatic driving, but generally only for the L1 to L3 level of driver assistance stage. The regulations also make it clear that self-driving cars on the road can only be used for experimental purposes, and the conditions of the road are also quite strict, requiring that a driver must be supervised in order to switch to manual driving mode in case of emergency.
From the perspective of driving algorithms, traffic regulations, and the V2X infrastructure required for intelligent transportation, L4/L5-level autonomous driving technology does not yet have the conditions for landing, so most of the mass-produced cars at this stage carry L2-level driver assistance technology based on "lane-keeping function+adaptive cruise control+active braking". L2 level driver assistance technology. Although many models are also equipped with a series of active safety assistance systems such as automatic parallel assist, automatic parking assist, adaptive cruise control and other active safety assistance systems on this basis, and the words "L2.5 level" and "L2+" will be played during publicity, in fact, they still belong to the L2 level category. The L2 class is the same as the L2 class.
Traditional car companies are far less aggressive in their publicity of driver assistance technologies, but in fact, those first-tier car companies have the same strong competitiveness, and compared to the new car companies, traditional car companies have a clear difference in their understanding of autonomous driving technology. Tesla as the representative of the new car companies expect the technology can directly control the vehicle driving, completely free the driver, but in recent years a number of accidents still proved that the control of the car to the machine more or less still have risks. The traditional car companies represented by Volvo, Cadillac, etc. believe that the purpose of the application of autonomous driving technology is to make the vehicle driving safer, and do not need to go to the level of autonomous driving as a gimmick.
This difference in philosophy is particularly evident in Cadillac's Super Cruise system, which is not only a label for Cadillac's technological advancement, but also an important milestone in GM's vision of "zero accidents". The Super Cruise system is not only a label for Cadillac's technological advancement, but also an important milestone for GM to realize its vision of "zero accident. In the past two years, GM has made great strides in electrification reform, and equipping traditional models with forward-looking technologies such as the Super Cruise system is also a way for GM to evolve and innovate.
In terms of self-driving technology, GM has both progressive development represented by the Super Cruise system and leapfrog development represented by the Cruise Automation self-driving technology, and the purpose of these two technologies is not only to free the driver, but also more importantly, to further reduce the number of accidents.
When testing Super Cruise in 2012, GM and its research partners conducted a large number of studies on the application of driver assistance features, which showed that in long-distance driving, automatic lane keeping and full-speed range adaptive cruise control can effectively help drivers reduce the load of driving, but this technology also has side effects, some drivers will be in the driver assistance function is turned on, and then distracted to do something else, for example, to do some other things. But the technology can also have the side effect that some drivers will be distracted by other things, such as breakfast, the office or the news, when the driver assistance features are turned on, which in turn are potential safety hazards. The U.S. National Highway and Traffic Safety Administration (NHTSA) has also shown in a study of more than 5,400 traffic accidents that 41 percent of accidents were caused by driver distraction. It was with this in mind that GM developed the Super Cruise system to include a driver attention retention system, which is linked to OnStar.
Also based on safety considerations, the release of Super Cruise has been delayed several times. 2014 General Motors first announced that Super Cruise would be officially launched in 2016, but in January 2016 Super Cruise was delayed because the bright light would affect the camera in front of the vehicle, making it impossible to confirm the vehicle's working conditions, making it impossible to confirm the situation in front of the vehicle, thus causing unstable speed. In GM's view, the Super Cruise system must be launched only under the premise of being able to fully guarantee driver safety, which is obviously different from the path of certain new car-making enterprises that prioritize the commercialization of driver assistance technology and then complete the technology update iteration through the accumulation of user data.
The Super Cruise system was finally installed on the production Cadillac CT6 in 2017, and was officially launched in the U.S. and Canadian markets in the fall of that year. As of May 2020, the Super Cruise system in North America has added more than 113,000 kilometers per week, and has achieved more than 8.8 million kilometers of safe driving without accidents, fully reflecting the maturity and reliability of this technology as well as safety.
In July 2020, two Cadillac CT6 28T models equipped with the Super Cruise system were launched in China, and the Super Cruise system immediately became a technological signature to attract consumers. With the two core technologies of Driver Attention Retention System and High Precision Map Data System, the integration of BLUELINE Blue Line Lane Center Drive Keeping System and Full Speed Domain Adaptive Cruise Control, supplemented by high-precision GPS positioning, and forming a powerful complement to the real-time camera and radar sensors of the original ESS Intelligent Guardian Safety System, the CT6 28T Super Cruise model even realizes driving on The CT6 28T Super Cruise can even be driven on the highway with both hands free, which also brings the driver a new driving experience that is more relaxed and intelligent.
Although it is still too early for Musk to talk about L5-level autonomous driving, it is undeniable that the current stage of autonomous driving technology is in a qualitative change, and new and old car manufacturers such as Azure, Geely, and Volvo have all said on different occasions that they may skip the L3 level and directly develop L4-level autonomous driving technology, which has also ignited consumers' expectations for the future. The safety of the Super Cruise system is not all, what consumers can get from the Super Cruise technology is the same General Motors has always been thinking about the problem.
In early 2020, the Super Cruise system will receive a technology upgrade that will allow it to automatically change lanes on the highway at the driver's request, while confirming that the road is safe. In addition, the vehicle control software, the user interface and the dynamic performance under Intelligent Drive Assist have all been upgraded to make the Super Cruise system more intuitive and easier to use. The enhanced Super Cruise system will be the first to be installed in North America in the new generation of Escalade, the 2021 CT5 and CT4.
New and old automotive companies not only have different starting concepts in automated driving technology, but also show different technical paths in the process of landing, with new forces focusing on the infinite possibilities of the future, and veteran automotive companies more cautiously considering the present. The new and old forces of intelligent driving landing battle, consumers in the end will stand on which side? Market sales will announce the final result of the vote
