Development of a combined steering torque overlay and differential braking strategy for unintended lane departure avoidance

Lane departure avoidance systems are required to assist actively the driver during drowsiness or inattention. Furthermore the unnecessary intervention by the lane departure avoidance system should be prevented because it can cause unexpected accidents. This paper presents a decision method of driver's intention and lane departure for reducing unnecessary intervention by lane departure avoidance system and a combined steering and differential braking strategy for lane departure avoidance. The proposed lane departure avoidance system was evaluated via human driver model-in the loop simulation.
