BYD said its assisted driving systems are now deployed across more than 60 vehicle models, and nearly 3 million vehicles, with severe accident rates reduced to one-sixth of human driving levels based on airbag-triggered incidents per 10 million kilometres, according to Autohome.

The figures were presented by Yang Dongsheng, BYD Group senior vice president and head of the Automotive New Technology Research Institute, during the 13th Intelligent Connected Vehicle Technology Annual Conference held in Shanghai on May 21.

Large-scale deployment

Yang said BYD began expanding its deployment of intelligent driving in early 2025 and now offers L2-assisted driving systems across almost its entire passenger-car lineup. According to the presentation, navigation-assisted driving activation rates exceeded 50%, while parking-assistance usage reached 86%.

BYD also stated that parking-related scratches and minor collisions declined to approximately one-fiftieth of human-driving levels under its parking assistance system. The company referenced its “God’s Eye” intelligent driving system and the associated parking-assistance guarantee program introduced in July 2025.

The speech comes ahead of BYD’s May 28 intelligent-driving strategy event, which has triggered industry speculation over a broader rollout of updated God’s Eye systems and additional vehicle integration plans.

Xuanji architecture and AI models

Yang attributed part of the system integration capability to BYD’s Xuanji Architecture, which combines the electronic architecture and electrification systems into a unified vehicle platform.

According to the presentation, BYD uses cloud-based world models and reinforcement learning for long-tail simulation training, supported by 190 million km of daily driving data generation. Yang said the company currently performs algorithm iterations every three days.

BYD also described the use of physical AI models on the vehicle side for predictive driving functions and defensive-response calculations. The company said the system combines visual occupancy network detection with lidar-based occupancy detection to identify suspended and hollow obstacles during parking scenarios.

Extreme-condition testing

The presentation also focused on extreme-condition development, including high-speed tyre blowouts, rain, snow, and low-adhesion road surfaces.

Yang said BYD’s integrated intelligent-electric platform can stabilise a vehicle within 200 milliseconds through coordinated motor and chassis responses. He stated that tire-blowout stability testing exceeded 200 km/h under company validation scenarios.

BYD added that it operates dedicated proving grounds for parking and driving-assistance development to combine simulation and physical testing.

Recent BYD product launches have increasingly integrated intelligent driving and fast-charging technologies. The updated Atto 3, introduced in China this week, adds 120 km of CLTC range alongside flash charging, while the upcoming Seal 08 sedan is scheduled to launch with rear-wheel steering and flash charging during the second quarter.

BYD sold 314,100 electrified vehicles globally in April 2026, up 6.2% month-on-month but down 15.7% year-on-year. March deliveries totalled 295,639 vehicles, according to Chian EV DataTracker data.
