What is the L4 Autonomous Driving Standard?

[Gael]

L4 autonomous driving standards are as follows: 1. In the "SAE Levels of Driving Automation" released by SAE (Society of Automotive Engineers), there are five other levels besides L4 autonomous driving. Among them, L0 is manual driving. According to SAE's definition, this level is entirely operated by the driver, including steering, braking, and throttle, all of which are judged by the driver. The vehicle is only responsible for executing commands, so this level is not considered autonomous driving. 2. L4 autonomous driving refers to high-level autonomous driving, which can achieve the entire driving process without any driver intervention, but it also has certain limitations, such as restricting the vehicle's speed to not exceed a certain value and having a relatively fixed driving area. It generally relies on real-time updated road information data support to achieve real-world scenarios such as automatic vehicle pickup and return, automatic platooning, and obstacle avoidance.

The L4 autonomous driving standard defines a highly automated level where vehicles can fully take over driving tasks under specific conditions, such as in urban areas or on highways, without requiring human intervention. This demands multiple sensors like radar and cameras to ensure accurate perception, as well as redundant designs to prevent failures, such as power backups or algorithm switching. The standard emphasizes reliable operation within predefined geofenced areas, handling maneuvers like turns and braking, based on the SAE framework. Regular testing of extreme performance is also required to ensure all-weather adaptability. I believe the core of the technology lies in enabling AI to make smooth and safe decisions.

From a safety perspective, L4 standards must ensure accident probabilities approach zero, with vehicles autonomously handling sudden dangers like pedestrian avoidance or pre-collision braking, requiring no human intervention. This involves system monitoring, real-time vulnerability fixes, and high-redundancy mechanisms to prevent single-point failures. Safety testing includes simulating all extreme scenarios and analyzing black box data to determine causes. These standards promote overall traffic reliability, and I believe public acceptance hinges on strict implementation.

Regulatory-wise, L4 standards must comply with government requirements, such as designated operating zones or passing institutional audits. Countries may restrict deployment to favorable weather conditions, ensuring test data is publicly transparent. Standards evolve with policy updates, with the focus on balancing innovation and public safety. I believe a gradual rollout based on real-world data is more prudent.

As a user, the L4 standard means the vehicle can fully drive itself in designated areas, allowing me to sit back and engage in other activities without needing to prepare to take over. The standard ensures reliable operation in changing environments, with a simple one-touch start. In case of failure, it automatically stops and calls for assistance, enhancing travel convenience. The core of the experience is trusting the system to seamlessly integrate life and travel.
