"This is the most capable autonomous driving system in the world today, and there is no one." On the night of the launch of the new HI version of Polar Fox Alpha S, Yu Chengdong, CEO of Huawei's terminal business, began to "brag" again.
The reason why the new HI version of the Polar Fox Alpha S, which was pre-sold for a full 386 days, attracted people's attention was because as early as the 12 kilometers of the "unmanned" more than a year ago, when the Alpha S equipped with Huawei's intelligent driving system successfully crossed the bustling downtown of Shanghai without manual intervention, and achieved the most difficult unprotected left turn of automatic driving, and the Pole Fox and Huawei temporarily harvested nearly half of the eyes on the beach.
From the perspective of technical capabilities, the Alpha S HI version has reached the automatic driving ability above the L3 level, but at present, the mainland has not allowed the L3 level of autonomous vehicles on the road, and the Alpha S HI version is calibrated as L2 level, which also means that no matter how BAIC and "Yu Dazui" (Yu Chengdong) bragged, if the automatic auxiliary driving system is turned on, the hands leave the steering wheel, and the owner is still responsible for the accident.
It is reported that after German regulators released L3-level autonomous driving on public roads last year, China may soon allow L3 passenger cars on the road. In fact, the mainland's automotive autonomous driving classification standard "Automotive Driving Automation Classification" has been implemented since March 1, 2022, but not many people know about it.
Based on the elements of the vehicle's perceptual decision-making and control, the GB will divide the driving automation system into level 0, emergency assistance; level 1, partial driving assistance; level 2, combined driving assistance; level 3, conditional automatic driving; level 4, highly automated driving; and level 5, fully automatic driving, a total of 6 levels.
Different levels of autonomous driving systems, the degree of driver's participation and the definition of accident liability are obviously different, of which the L3 level is an obvious watershed.
Level 0 is emergency assist, where the driver needs to perform all dynamic driving tasks while also supervising the assisted driving system. The driver assistance system is only responsible for the detection and response of some targets and events, and when the driver requests the automation system to exit, the car can immediately release control of the system. Features such as FCW Front Collision Warning and LDW Lane Departure Warning are classified as Level 0 autonomous driving.
Level 1 is partial assisted driving, and like level 0, it belongs to assisted driving with obvious restrictions, the driver can activate and close the auxiliary driving system, and can take over the vehicle immediately at any time, and the vehicle of this level has the ability to control the direction or acceleration and deceleration of the vehicle. ACC Adaptive Cruise or LKA Lane Keeping Assist is categorized here.
Level 2 is the combination of assisted driving, in the continuous vehicle lateral and longitudinal motion control, will be fully responsible for the automatic driving system, the vehicle has both adaptive cruise and lane keeping assist functions, but the driver still has to take over the vehicle at any time, otherwise there is a problem, the manufacturer is not responsible.
Level 3 is conditional automatic driving, is a watershed between assisted driving and automatic driving, the driver can let go of their hands and feet, while the attention can be diverted from the driving environment for a long time, and once there is a problem, the manufacturer is responsible. But that doesn't mean the driver can sit back and take over a faulty vehicle if the system fails or exceeds operating conditions.
Level 4 is highly automatic driving, still belongs to the restricted automatic driving, when the automatic driving system is activated, the driver's driver role becomes a passenger, no longer a backup user, unless the automatic driving system artificially withdraws, the driver's role can be restored. In fact, at this level of automatic driving, the driver's seat is no longer standard.
Level 5 is fully autonomous driving, which is basically the same as Level 4 in function, but in the scope of design and operation, there are no longer restrictions on operating conditions, except for restrictions such as commercial and regulatory factors, and at the same time, the automatic driving system can independently complete all operations and decisions.
Before the implementation of the national standard for autonomous driving, the main reference in China was the automatic driving classification standard of the American Society of Automotive Engineers (SAE). The main difference between the new national standard and the SAE automatic driving classification is that the national standard stipulates that "target and event detection and response" is completed by the driver and the system for level 0 to 2 automatic driving. SAE requires that the goals, events and decision-making tasks of L0 to L2 autonomous vehicles be completed by the driver. And the national standard requires all levels of autonomous driving to allow the release of control of the system, which SAE did not mention. There is little difference in other aspects.
At present, the highest level of assisted driving in China is 2 levels, and the driver is not allowed to take off the steering wheel. In the transformation of the new four modernizations of the automotive industry, the most important point of struggle for intelligence is in unmanned driving, some car brands have excessive publicity on automatic driving, consumers blindly believe in vehicle automatic driving, resulting in the occurrence of some accidents, and the truth of the accident is difficult to sort out, and the ultimate harm is still consumers, car companies and consumers should rationally understand and use the intelligent driving function of the vehicle, otherwise it will be inverted.
