This paper presents a Autonomous Emergency Braking(AEB) system using additional adjacent path target monitoring scheme for performance enhancement. For AEB system performance enhancement in mid-high speed region(>60kph in relative speed), Braking-TTC(Time to Collision)-Elevation tuning with conventional single target monitoring concept can lead sensitive or false activation of AEB braking. In this paper we propose advanced scheme of AEB using additional targets adjacent to driving path of subject vehicle. Using decision concept of subject vehicle’s steerable path for targets in adjacent path can elaborate collision avoidable speed or collision speed of AEB system in mid-high speed region, in case there were not enough steerable path for collision avoidance. Based on that scheme,we designed adaptive AEB control logic and validate its functionality with the postulated scenarios. The result shows that different AEB activation result along to the each scenario in simulation and real vehicle test and thay are written in experiment result section.
