CATL Times Intelligence Discusses Challenges of Native L4 Chassis

[Technology Outlook] Cai Jianyong, CTO of CATL Times Intelligence, elaborates on bottlenecks hindering large-scale deployment of L4 autonomous vehicles.

Core Insight: L4 Is a New Species, Not an Upgrade of Traditional Vehicles

Cai Jianyong emphasized that L4 autonomous vehicles, due to the absence of a human driver as a fallback, require a complete redesign of foundational engineering logic. Their reliability faces severe challenges, especially under high-intensity operational conditions.

Key Data: 10 to Over 100 Vehicle Breakdowns Per Day in a Single City

Based on a fleet scale of 100,000 autonomous vehicles (including robotaxis, robovans, etc.), intensive usage leads to 10–100+ vehicle failures daily, highlighting the urgent need for enhanced chassis durability and redundant system design.

Strategic Foundation: Native L4 Chassis Is the Key to Breaking Through

As an intelligent chassis company under Contemporary Amperex Technology Co. Limited (CATL), CATL Times Intelligence is focusing on steer-by-wire, braking redundancy, and modular platforms to advance the implementation of a native chassis architecture tailored for L4 autonomy.
