An improved control method of automatic emergency braking (AEB) for rear-end collision avoidance is proposed, which combines the advantages of a time-to-collision (TTC) control algorithm and professional driver emergency braking behavior. The TTC control algorithm mostly adopts phased braking, and although it can avoid collision effectively, the braking process is radical and brake comfort is poor. The emergency braking system with professional driver fitting (PDF) has good comfort and can also avoid collision successfully. However, its brake trigger time is too early, which leads to the stopping distance being too large under high-speed conditions and affects the road utilization. By combining the advantages of the two control methods, an improved control algorithm for AEB is proposed. When the TTC value is not greater than a predetermined limit, the PDF control switch will be closed to avoid collision. Through the Matlab/Simulink and CarSim co-simulation platform, the European New Car Assessment Programme (Euro-NCAP) test scenarios are constructed. The results show that the proposed AEB control algorithm can not only ensure the effectiveness of collision avoidance and brake comfort but also make the stopping distance to be not too large in the case of high-speed collision avoidance situations.
