Research on control strategy of automatic emergency brake system based on Prescan

A new collision avoidance strategy for an autonomous emergency braking system is proposed in this paper. The risk assessment model on the emergency braking behavior of driver in real traffic scenarios is developed. A collision avoidance strategy with two levels of warning and two levels of braking intensity is proposed according to the driver response, decision and operation time. Simulation model is established by using Prescan software. The simulation results show that the proposed collision avoidance strategy can avoid collision entirely or mitigate the severity of collision.
