The China Automotive Engineering Research Institute (CAERI) carried out specialized testing on combined driving assistance systems across more than 40 popular vehicle models. The testing scenarios encompassed over 20 highway traffic situations, such as the sudden disappearance of a leading vehicle, abrupt lane changes, and animals crossing the road. Additionally, more than 30 complex urban-road risk scenarios were included, such as navigating roundabouts, handling multiple pedestrians crossing simultaneously, and dealing with two-wheeled vehicles cutting in. After conducting tens of thousands of test verifications and analyzing thousands of real-world traffic accident cases, the results revealed a marked improvement in the overall standard of China’s combined driving assistance technology. Between January and July 2025, the market penetration rate of passenger vehicles equipped with combined driving assistance systems reached 62.58%. Experts have highlighted that the integration of combined driving assistance systems into vehicles represents an inevitable trend in the automotive industry’s evolution. As technology progresses and market adoption increases, the industry will need to address existing shortcomings moving forward.
