This paper proposes an autonomous emergency braking (AEB) system that takes into account road conditions at an intersection, using vehicle-to-vehicle (V2V) communication. The conventional AEB system considers the friction characteristics of a particular type of road, and thus has a fixed timing for activating the automatic braking without regard to different road conditions. Such an AEB intervention feature has performance limitations in actual road conditions. To overcome these drawbacks, this study proposes a control method that adjusts the automatic brake application time to road conditions. Additionally, collision risks at an intersection were calculated using various road friction coefficients and the V2V-based speed inputs from adjacent vehicles. The efficacy of the proposed AEB system was validated through tests under various scenarios, applying the road friction coefficient and vehicle speed as variables. The tests verified the improved collision avoidance performance of the proposed AEB system’s control method compared to the conventional method.
