In order to improve performance of automatic emergency braking (AEB) system, this article firstly analyzes the data from road traffic accidents, and concludes that the collision frequency and accident fatality rate are higher when the electric two-wheeler drives head-on when the motor vehicle turns left, then summarizes this accident scene as a typical application scenario of AEB system. The PreScan-MATLAB-CarSim active safety simulation test model is built using real vehicle parameters and the technical parameters of the sensor, and the type, number of the sensors and cameras needed and reasonable range of emergency braking parameters are determined by simulation. Finally, driving robot and small-sized bearing robot are employed to build an accident test scene, and the AEB parameter matching and simulation parameter verification are completed. The results show that the parameters can satisfy the requirement of development.
