Adaptive Advanced Emergency Braking on Combined Road Friction Coefficients

Abstract

In this study, an Advanced Emergency Braking System (AEBS) is adopted to the combined road friction coefficients by proposing an emergency steering maneuver. AEBS is one of the significant driver assistant systems to avoid rear-end collisions. However, in special cases, such as the sudden decrease of road friction coefficient during braking, AEBS may work with the autonomous emergency steering systems to prevent inevitable rear-end collisions. The originality of this study arises from the necessity of the adaptation of the AEBS to work in cooperation with the autonomous emergency steering systems. A predictive controller was used to support the emer-gency braking maneuver with an autonomous steering maneuver via observing the yaw rate of the vehicle. The predictive controller was developed in MATLAB/Simulink interface and then applied into the IPG/CarMaker environment. The results proved that the predictive controller maintained the vehicle lateral stability without causing any type of collisions.
