As can be seen from the above table, "level 0" belongs to "emergency assistance", and the on-board system only provides emergency assistance functions such as lane departure warning, frontal collision warning and automatic emergency braking. At this level, vehicles are more of a safety protection function.
"Class 1" is "partial driving assistance", that is, both the driver and the system have the right to drive, and the system can control the vehicle horizontally or vertically under the design working conditions. In daily life, it is common to see that vehicles have the function of adaptive cruise, and it is generally considered that they have the ability of 1.
The "second level" is "combined driving assistance", and the system basically has the ability to master the driving right, and the system can control the vehicle horizontally and vertically under the design working conditions. In daily life, it is generally believed that vehicles have the functions of lane keeping and adaptive cruising at the same time, and it is generally considered that they have the ability of level 2.
"Three-level" realizes "conditional automatic driving", and the system can basically complete all dynamic driving tasks under design conditions. The biggest difference here is that the clause "under design operation conditions" restricts the third-level operation area, such as closed sections such as expressways, or in special circumstances, it is a restrictive clause. In addition, if the system can't cope, the driver of the vehicle or other users (such as security personnel or remote controllers) can start the control.
"Level 4" belongs to "highly automatic driving". Under the designed working conditions, the system can complete all the driving tasks and take over the driving tasks. In this case, the system can handle all situations by itself, basically without driver intervention. However, it should be noted that the restrictive attribute is still "under design and operation conditions".
"Level 5" belongs to "fully automatic driving", which means that the system can complete all dynamic driving tasks and take over the dynamic driving tasks under any conditions, except "under the design operation conditions", which means that the car can realize automatic driving within the legal driving range without the intervention and taking over of the driver.
Second, the judgment of advanced automatic driving Personally, the core significance of advanced automatic driving lies in whether the driving subject can be transferred from the driver to the vehicle. In the above classification standards, L3 used to belong to the driver as the driving subject, and after L3, it is more of a vehicle as the driving subject, and L3 itself is the stage where the driver and the vehicle drive together.
