<div>The key issues of automatic emergency braking (AEB) control algorithm are when
and how to brake. This article proposes an AEB control algorithm that integrates
risk perception (RP) and emergency braking characteristics of professional
drivers for rear-end collision avoidance. Using the formulated RP by time to
collision (TTC) and time headway (THW), the brake trigger time can be
determined. Based on the professional driver fitting (PDF) characteristic, the
brake pattern can be developed. Through MATLAB/Simulink simulation platform, the
European New Car Assessment Programme (Euro-NCAP) test scenarios are used to
verify the proposed control algorithm. The simulation results show that compared
with the TTC control algorithm, PDF control algorithm, and the integrated PDF
and TTC control algorithm, the proposed integrated PDF and RP control algorithm
has the best performance, which can not only ensure safety and brake comfort,
but also improve the road resource utilization rate.</div>
