The vehicle dynamics model and simulation scenario are established in Prescan, and the AEB(autonomous emergency braking system) algorithm and GMA(giant magnetostrictive actuator) are combined in simulink to conduct co-simulation analysis on two types of working conditions, CCRm(Car to Car Rear Moving) and CCRs(Car to Car Rear Stationary). In the case of CCRm, the speed of the ego vehicle and the target is equal to 20km/h due to emergency braking at 4.8s. The shortest distance between the two vehicles is 3.8m, and the speed is further reduced to 11km/h to achieve collision avoidance and remove the alarm; Under the other condition, the self-propelled speed decreases to 0 at 5.7s, and the shortest distance between the two vehicles is 1.2m, which realizes collision avoidance and lifts the alarm. The effectiveness of the combination of AEB algorithm and GMA is verified in both cases. The AEB system does not intervene prematurely, effectively realizes collision avoidance, and improves the safety and comfort of the drivers and passengers.
