What does Level 4 autonomous driving mean?
2 Answers
Level 4 autonomous driving refers to high-level autonomous driving, which can achieve the entire driving process without any driver intervention. The following is an introduction to autonomous driving-related content: 1. Restrictions: The vehicle speed is limited to a certain value, and the driving area is relatively fixed. It generally relies on real-time updated road information data support to achieve real-world scenarios such as automatic vehicle pickup and return, automatic convoy cruising, and automatic obstacle avoidance. 2. Level 2 autonomous driving: Level 2 is partial autonomous driving, which can automatically perform acceleration, deceleration, and steering operations simultaneously. This means that adaptive cruise control and lane-keeping systems can work together. Currently, most car manufacturers have achieved Level 2 autonomous driving technology.
As an enthusiast of automotive technology, I find Level 4 autonomous driving incredibly exciting. It refers to vehicles being able to fully control driving operations under specific conditions or within designated areas, such as highways or urban zones, without requiring any manual intervention from the driver. You can relax, enjoy the scenery, or handle other tasks inside the car. This represents a significant advancement over Level 3, which still requires drivers to be ready to take over the wheel at any moment. Level 4 completely liberates humans, with the system independently managing all steering, acceleration, and braking. Currently, many major companies are testing this technology—for instance, Waymo's taxi service operates only in specific cities. In the future, this technology could reduce traffic congestion and accidents caused by human error, making our travels safer and more comfortable. However, it's important to note that Level 4 isn't omnipotent; it functions only within pre-mapped areas and becomes ineffective beyond those boundaries. Therefore, I look forward to more practical applications that will popularize this technology, transforming our daily commutes with greater convenience and enjoyment.
