Intelligent cockpit has entered the "AI-enabled" era. At the recent ByteDance Engine FORCE Original Power Conference, BYD and ByteDance Engine officially announced a deep collaboration, integrating the Douba large model of ByteDance comprehensively into BYD's DiLink intelligent cockpit system. This covers all currently sold models of five brands: Yangwang, Chengshi, Fangchengbao, Dynasty, and Ocean, becoming the largest and most widely covered case of large model application in intelligent cockpits among automakers globally.

Douba Large Model Deeply Embedded, Cockpit Interaction Fully Upgraded

This collaboration is not simply adding a voice assistant, but deeply integrating the capabilities of the Douba large model into the core experiences of the cockpit:

- Intelligent Voice Interaction: Supports scenario-based continuous conversation, multi-intent recognition, and context understanding. Users can naturally express requests like "lower the air conditioning, play some light music, and navigate to the nearest charging station";

- Personalized Content Recommendations: Proactively recommends music, podcasts, short videos, and local lifestyle services based on user preferences and itineraries;

- Travel Service Loop: Integrates the ecosystem of charging, parking, and dining, achieving a one-stop service scheduling experience of "leaving at a moment's notice."

Beyond Voice, Full-Scenario Smart Experience Coverage

The collaboration also extends to multiple key functional modules:

- Full-Scenario Digital Key: Supports no-touch entry methods such as phones, watches, and NFC, automatically matching personalized settings like seats and ambient lighting with AI-based identity recognition;

- Cockpit Entertainment Upgrade: Achieves immersive experiences such as "image recognition," "voice-based playback," and "AR navigation explanation" through multimodal understanding;

- Cross-Device Collaboration: Integrates with users' phones and IoT home devices, realizing "seamless continuation between leaving and entering the vehicle."

Why Douba? Scenario Collaboration Is Key

Analysts believe that BYD chose the Douba large model for its unique advantages in content ecology, multimodal understanding, and verification with hundreds of millions of user scenarios. The Douba App has over 200 million monthly active users, and its recommendation algorithms, voice interaction, and short video comprehension capabilities have been deeply refined, enabling rapid empowerment of high-frequency usage scenarios in vehicles. Meanwhile, ByteDance Engine provides edge-cloud collaboration, low-latency inference, and private deployment capabilities, ensuring data security and response speed.

Industry Significance: Large Models on Vehicles Enter the "Mass Delivery" Stage

Previously, AI large models on vehicles were mostly limited to flagship models for pilot testing. However, BYD's full series configuration marks the shift of large model cockpits from "technical highlights" to "basic configurations." In the context of increasing homogenization of intelligent electric vehicles, personalized and proactive services driven by large models may become the core competitiveness of the next stage.

AIbase believes that the collaboration between BYD and ByteDance Engine is not only a technological integration but also an important step toward the localization of China's intelligent car ecosystem — from chips to operating systems, and then to large models, the local technology stack is fully taking over the "brain" of the intelligent cockpit. This AI implementation validated by millions of mass-produced vehicles may redefine the standards of global intelligent mobility experiences.
