Development of a Combined Steering Torque Overlay and Differential Braking Control for Side Crash Prevention

This paper presents an algorithm for side crash prevention systems using a combined steering torque overlay and differential braking control. This system prevents lane changes when a driver attempts to lane change despite existence of a neighboring vehicle in the blind spot. For this purpose, the system needs some technologies for detecting a vehicle in blind spot, judging driver´s lane change intention and controlling a vehicle to avoid side crash. In this paper, we focus on judging driver´s intention and controlling a vehicle. The proposed system was evaluated via human driver model-in the loop simulation.
