何为L3级自动驾驶？

Core Insights - The Ministry of Industry and Information Technology officially announced the first batch of L3 conditional autonomous driving vehicle permits in China, marking a significant step towards the commercialization of L3 autonomous driving from the testing phase [1][12]. Summary by Category L3 Autonomous Driving - L3 autonomous driving allows the system to perform all dynamic driving tasks under specific design conditions, with the user required to be ready to take over when necessary [8][19]. - The vehicles approved for L3 operation are designed for urban congestion and highway scenarios, and will be tested in designated areas in Beijing and Chongqing [1][12]. Levels of Driving Automation - Driving automation is classified into six levels (0 to 5) based on the extent of dynamic driving task execution, role allocation, and design operational limits [13][14]. - Levels 0 to 2 are categorized as driver assistance, where the human driver remains the primary operator, while levels 3 to 5 represent varying degrees of automation where the system can take over driving tasks [13][14]. Definitions of Automation Levels - Level 0: Emergency assistance, where the system cannot perform dynamic driving tasks but can assist the driver in certain situations [5][16]. - Level 1: Partial driver assistance, where the system can control either lateral or longitudinal movement but requires driver supervision [6][17]. - Level 2: Combined driver assistance, where the system can control both lateral and longitudinal movements under specific conditions, still requiring driver oversight [7][18]. - Level 4: Highly automated driving, where the system can perform all driving tasks and execute a minimal risk strategy without user intervention [9][20]. - Level 5: Fully automated driving, where the system can operate under any driving conditions without human intervention [10][21].
