The operating speed range of the Automatic Emergency Braking (AEB) system varies by vehicle model and brand, but the activation interval of mainstream systems is typically between 10 km/h and 135 km/h, with specific parameters depending on technical configurations and algorithm design. For example, the forward AEB of some models is effective in the range of 10 km/h to 80 km/h, while high-end systems like Huawei's QianKun Omnidirectional AEB can cover 4 km/h to 150 km/h and recognize various obstacles such as pedestrians and vehicles. In practical applications, AEB performs best in responding to sudden situations at low speeds (e.g., 30 km/h to 60 km/h on urban roads), significantly reducing collision risks; in high-speed scenarios (over 100 km/h), while it may not completely avoid accidents, it can mitigate impact severity. Currently, AEB is installed in over 55% of passenger vehicles, exceeding 95% in premium new energy models. However, users must remain vigilant and avoid over-reliance on driver assistance systems.
