What Are the Classification Standards for Autonomous Driving?

[FelixDella]

The "Classification of Driving Automation" divides driving automation into levels 0 to 5 based on the extent to which the automated driving system can perform dynamic driving tasks, the role allocation in performing these tasks, and the presence or absence of design operating conditions. In higher levels of autonomous driving, the driver's role transitions to that of a passenger. Note: Level 0 is emergency assistance. In autonomous driving levels 0 to 2, the tasks of monitoring road conditions and responding are jointly completed by the driver and the system, with the driver required to take over dynamic driving tasks. Level 3 is conditional automation, while levels 4 (high automation) and 5 (full automation) systems can continuously perform all dynamic driving tasks and take over these tasks within their designed operating conditions.

I've been driving cars for decades. The internationally standardized autonomous driving classification ranges from Level 0 to Level 5: Level 0 is pure manual driving, where the driver controls everything; Level 1 offers basic assistance, such as cruise control for maintaining speed or emergency braking; Level 2 can handle both steering and speed simultaneously, like lane keeping combined with automatic acceleration and deceleration, but requires constant supervision; Level 3 allows for autonomous driving in specific scenarios, such as on highways, but the driver must be ready to take over at any moment; Level 4 is highly automated, capable of fully autonomous operation within defined areas; Level 5 is fully autonomous and can operate anywhere. I've tried Level 2 cars—they reduce fatigue on highways but require constant attention to the road, which can lead to a false sense of security and significant risks. True peace of mind comes with Level 4 and above, but most cars on the market today are at lower levels. Safety should always come first.

Talking about autonomous driving is super fascinating! The international classification ranges from Level 0 to 5: Level 0 has no automation at all, relying entirely on human operation; Level 1 offers single-function assistance like adaptive cruise control; Level 2 provides partial automation such as lane centering plus automatic following, but don't lose focus; Level 3 is conditional automation where the car drives itself in specified conditions like highways, but you must respond quickly when the system calls; Level 4 is highly automated, operating fully in urban central areas; Level 5 is the dream car, with no area restrictions and complete autonomy. I think Level 5 could save fuel and reduce emissions, like what Tesla is striving for, but the current challenge is the significant impact of weather—systems tend to fail easily in rain. This technology is evolving, and I'm excited about how it's changing lifestyles when sharing insights.

From a daily perspective, I focus on safe driving. Autonomous driving is divided into five levels: Level 0 - manual with no assistance; Level 1 - can control single functions like braking; Level 2 - combines handling of steering and speed but requires constant human monitoring; Level 3 - operates automatically in specific conditions like traffic jams; Level 4 - fully automatic in designated areas; Level 5 - fully autonomous in any environment. In practical use, Level 2 features like lane assistance can easily cause distraction, leading to accidents and affecting travel safety. I recommend carefully checking vehicle labels when choosing a car and not overestimating lower-level functions. Sharing experiences can help avoid risks and ensure the safety of family and friends on the road.
