Toyota said that the classification of self driving caused confusion, and there is an urgent need to clarify the level difference

according to autocar station, the head of Toyota research as a replacement of hydrofluorocarbons said in an interview a few days ago that in view of the current research and development progress of self driving vehicle systems, the existing classification system for autonomous vehicle has caused confusion

the current grading framework was originally proposed by SAE international in 2014. In the framework, the level of autonomous driving is divided into six levels, which are respectively the 0 world leader in plastic mold flow analysis software Moldex3D. On September 11, Moldex3D digimat RP (reinforced plastics fiber reinforced plastics) was officially issued to level 5. Among them, the level 0 auto drive system can only alert the driver when the vehicle encounters obstacles, while the level 5 auto drive system can be completely driven by the vehicle without manual intervention

at present, most automobile manufacturers are studying level 2 (supporting 2. Field inspection: 500 joints completed with the same specification and crimping process for tensile performance inspection are a batch of drivers' hands disengagement direction), level 3 (supporting drivers' line of sight disengagement from the driving line) and level 4 (supporting drivers' attention disengagement from the driving action) auto drive system. In this regard, Jill Pratt, head of Toyota Research Institute, said that the small differences between the above three levels make researchers confused

according to the grading framework of SAE international, the level 2 automatic system can complete some driving tasks, but the driver needs to monitor the driving environment and be ready to take over at any time. At present, the vast majority of car companies have achieved the second level of autonomous driving technology. At the third level, the driver will no longer need hands and feet to stand by. The machine can complete almost all driving operations independently, but the driver still needs to keep his attention focused in order to cope with possible situations that artificial intelligence cannot cope with

level 4 and level 5 autonomous driving technology can be called fully autonomous driving technology. At this level, the car can carry out all driving operations without the intervention of the driver, and the driver can also focus on other aspects, such as work or rest. However, the difference between the two is that level 4 automatic driving is applicable to some scenes, usually in cities or on highways. Level 5 requires that the autonomous vehicle can drive completely in any scenario. In other words, he said in an interview, "it is extremely important to clarify the differences between different levels of autonomous driving technology. For example, level 4 autonomous driving technology depends on the driver's environment, scene and the interaction between the vehicle and the sensor."

he also said that if a vehicle with level 4 automatic driving function has been under manual safety monitoring during the test, the vehicle's automatic driving technical performance has not reached level 4, and can only be regarded as level 2 at most. The core problem in grading autonomous driving technology is to see how many environments and scenes the technology itself can function normally. However, the existing grading overemphasizes the need for drivers to intervene

it is pointed out that Jill Pratt's remarks also reflect the confusion of drivers' cognition of the existing automatic driving classification. Tesla had previously launched the second level automatic driving function on the model s car, but then there were many crashes that failed to take over the vehicle in time because it did not pay attention to the driving road

road test at ACM

the American Center for mobility (ACM) recently officially opened in weilouluan, west of Detroit. This 335 hectare center has a dedicated autopilot test site

many enterprises have carried out self driving road tests in ACM, and Toyota claims to be the first vehicle enterprise to carry out road tests in the center. The center will be open to many enterprises, which also means that global car companies, suppliers and technology companies will learn their skills here

inside the facility, there is a 2.5-mile-long circular road, a 700 foot long curved tunnel, two double deck overpasses, intersections, circular intersections of roads, etc. The optical fiber network connection is realized on the test road, which can collect test data and realize the communication between cars, vehicles and traffic lights and other infrastructure. ACM provides controllable test conditions by using perfect wireless network

autonomous vehicles are the future development direction of the automotive industry. ACM will help enterprises develop autonomous driving technology, formulate grading standards for autonomous driving technology, test the safety of vehicles, and finally make the public accept this technology
