What Does a Level 2 Autonomous Driving Assistance System Include?
2 Answers
Adaptive cruise control, AEB (Automatic Emergency Braking) system, and lane keeping assist are the "basic" functions of Level 2 autonomous driving. Here is more information about autonomous driving levels: 1. Level 1: Can assist the driver in completing certain driving tasks, such as the adaptive cruise control (ACC) function installed in many models, where radar is used to control the distance between vehicles and adjust speed in real-time, widely applied in many domestic models. 2. Level 2: Can automatically complete certain driving tasks and, after processing and analysis, automatically adjust the vehicle's state. For example, Tesla's lane keeping function belongs to this level, which can not only control acceleration and deceleration but also manage the steering wheel. However, the driver still needs to observe the surrounding conditions to ensure safe operation. 3. Level 3: At this level, the vehicle is controlled by a more logical driving computer, and the driver does not need to keep hands and feet ready. The vehicle can independently complete driving operations in specific environments, but the driver cannot sleep or rest. When artificial intelligence cannot make accurate judgments, manual operation is still required. The recently launched BMW X7 claims to have achieved this level of autonomous driving technology.
The Level 2 autonomous driving assistance system is quite practical in our daily driving. It actually includes several core functions that make driving easier and safer. I personally frequently use Adaptive Cruise Control (ACC), which automatically adjusts speed to follow the car ahead, freeing up my right foot. There's also Lane Keeping Assist (LKA), which helps correct the steering when I turn or drift out of the lane, making it feel like having a co-driver assisting me. Blind Spot Monitoring (BSM) provides warnings during lane changes to avoid collisions. Additionally, Automatic Emergency Braking (AEB) automatically brakes in emergency situations to prevent rear-end collisions. These functions work together to make highway driving less exhausting, but remember to keep your hands on the wheel—it's just an assistance system, not fully autonomous. Overall, it enhances the driving experience and reduces fatigue during long trips.
