AEB System for a Curved Road Considering V2Vbased Road Surface Conditions

Abstract

Abstract. In this study, a brake intervention time algorithm of an ego vehicle is proposed to consider various road surface conditions when driving, through vehicle to vehicle (V2V) communication with a front vehicle in a curved road. Conventional autonomous emergency braking (AEB) systems have a consistent brake intervention time regardless of road surface conditions. To avoid a collision with a vehicle in front, a control method is introduced, in which the brake intervention time changes according to the road surface conditions. To verify the brake intervention time according to various road friction factors, the simulation scenario reflected the vehicle velocity and road curvature radius. The control method, which changed the brake intervention time according to the road surface conditions, had better collision-avoidance performance than the conventional AEB system control method.
