Abstract: With the rapid development of intelligent driving assistance systems, automated emergency braking (AEB) system is a key part of intelligent navigation, has become an important technical measure to reduce road accidents, and has become an inevitable trend in the development of the automotive industry. At the same time, the working efficiency of AEB system is directly related to the safety of drivers and passengers. This article first analyzes the working principle of the AEB system; Secondly, theoretical analysis will be conducted on the time to collision (TTC) model, Mazda model, and Honda model; Finally, analyzes the braking effect under various working conditions through actual vehicle testing. The results show that, under the premise of not disturbing the driver's normal driving, the TTC model has the best longitudinal collision avoidance performance among these three models; The three models can form a good comparison on the vehicle, and there is no rejection reaction to the vehicle in the models.
