What is the domestic autonomous driving classification?
2 Answers
Domestic autonomous driving is currently divided into 6 levels, from L0 to L6. Currently, China is at L4. Technical principles of autonomous driving: Automotive autonomous driving technology includes video cameras, radar sensors, and laser rangefinders to understand surrounding traffic conditions, and navigates the road ahead through a detailed map (collected by human-driven vehicles). All of this is achieved through Google's data centers, which can process vast amounts of information collected by the car about the surrounding terrain. In this regard, autonomous vehicles are equivalent to remote-controlled or intelligent cars of Google's data centers. Automotive autonomous driving technology is one of the applications of IoT technology. Energy consumption of autonomous driving: Autonomous vehicles can encourage carpooling, significantly reducing car usage and creating "highway trains." These highway trains can reduce energy consumption and increase the capacity of major roads. In terms of time savings, the U.S. Department of Transportation estimates that people spend an average of 52 minutes commuting each workday. In the future, people can use this time more efficiently.
China's autonomous driving classification standard follows the international L0 to L5 six-level system. L0 means no automation at all, where drivers must control the steering wheel and throttle themselves. L1 offers minor assistance, such as adaptive cruise control or lane keeping. L2 is the most common level, now equipped in many new cars, which can simultaneously control steering and speed, making highway driving easier. However, drivers must remain attentive and keep hands on the wheel. L3 is more advanced, allowing the system to drive autonomously on specific road sections and actively avoid obstacles, but it may require the driver to take over at any time. L4 eliminates the need for steering wheel control, like some unmanned taxis operating in certain areas. L5 is the ultimate goal, requiring no human intervention in any road condition. The key point to remember is that the responsibility division between L2 and L3 is the critical watershed.
