In some sci-fi movies, we will find some bridge segments. For example, in the future world, people travel by artificial intelligence and self-driving. As long as they enter the destination, these smart vehicles can travel through any corner of the city, and they are enviable. . Speaking of these, maybe our current technology can not be reached, but not far, because the self-driving car has arrived. Some people think that autopilot is just an auxiliary tool, and some people think that it is just a gimmick. However, from the current point of view, not only some auto companies such as Tesla, Volkswagen, Audi, etc. in the automotive field are studying, but even some cross-selling giants such as Google, Baidu and Apple are involved. It is conceivable that anyone who masters this technology in the future may come to a technological revolution. Then when it comes to autonomous driving, you have to figure out the fact that what kind of car can be called autonomous driving, so in order to distinguish and define more, automatic driving grading becomes a big deal. At present, the two classification systems recognized by the global automotive industry are proposed by the US Highway Safety Administration (NHTSA) and the International Society of Automated Engineers (SAE), which divide the automatic driving into L0 to L5 levels and assume corresponding responsibilities. . L0 (manual driving) As the name suggests, the L0 class is the most traditional entry-level car. It is fully controlled by human beings. These cars are mostly transitive tools in the traditional sense. They do not have any automatic driving ability and the price is relatively cheap. Common in the field of miniature electric vehicles and compact cars. L1 (assisted driving) With the popularization of intelligent technology, some intelligent configurations, such as lane keeping, automatic cruising and automatic braking systems, and automatic parking are also in this category. These configurations are common on many models. In certain situations, these configurations provide an intelligent aid to improve driving comfort, but the overall driving environment is still human. L2 (partial automatic driving) More intelligent than assisted driving, the car can control a variety of car functions, and is equipped with a driver assistance system to a certain extent to achieve automatic driving. For example, ACC adaptive cruising and turning the turn signal can realize automatic lane change and so on. At this stage, although the machine can perform some combined driving needs independently, the driver still needs to prepare both hands and feet on the steering wheel and brake pedal. These Mercedes-Benz Driver Assistance Systems, Tesla Autopilot, Volvo Pilot Assist, and the BMW 5 Series Adaptive Cruise are also in this category. L3 (conditional automatic driving) This level of autonomous driving technology, the driver will no longer need to be on standby, the vehicle can independently control most of the driving operations, including environmental monitoring, but the driver still needs to maintain concentration to deal with possible artificial intelligence Can't cope with the situation. At present, the new Audi A8 is equipped with the Audi AI autopilot function, which can achieve automatic driving in congested road conditions below 60km/h. L4 (highly automated driving) At this level, the car is basically fully self-driving, without the intervention of the driver, and the internal design also eliminates the man-made control facilities such as the steering wheel. However, this level has certain limitations, which are usually applied to specific scenarios such as ports, parks, scenic spots and airports. At present, the L4-class models that have been mass-produced include Google's self-driving cars and the self-driving bus "Apollon" based on Baidu's Apollo 3.0 technology platform. L5 (fully driven) The L5 level does not require an environmental limit compared to the L4, enabling autopilot in any scenario. At present, the L5-class model is the self-driving concept car Sedric released by Volkswagen. However, this car is not in mass production. It is only in the experimental stage. It is expected that this technology will be applied to other production models in the future. The result is still expected. .
