Abstract: Based on the analysis of the applicability of three different autonomous emergency braking (AEB) control models in different crash scenarios, and the China in-depth accident study (CIDAS) China traffic accident in-depth research database, PreScan software is used to build the accident scene, and Simulink is connected to add the vehicle control model, and the real collision scene is tested by reconstructing the CIDAS traffic accident database. The simulation results verify that the autonomous emergency braking (AEB) control strategy based on the safety distance model can effectively avoid rear-end collision accidents or mitigate the harm caused by collisions, among which the Mazda model algorithm is relatively conservative and suitable for high-speed scenarios, and the Honda model algorithm and Berkeley model algorithm are relatively radical and suitable for medium and low-speed scenarios, which provides a reference for the evaluation and improvement of active safety technology.
