Expert drivers' deceleration patterns in last-second braking will be formulated using a perceptual risk index for the approach and the proximity of a preceding vehicle as examples of comfortable braking patterns. It will be shown that the formulated braking pattern can uniformly generate a smooth deceleration profile for many approach conditions. In(More)
This paper presents a hierarchical modeling strategy of the driving behavior based on the multiple levels of abstraction of the underlying dynamics. In order to realize this idea, a new mathematical model, Hierarchical PieceWise ARX model (Hi-PWARX model) is proposed. The identification scheme for the Hi-PWARX model is developed by synthesizing the ideas of(More)
Several driver-assist systems have been developed to enhance driver comfort, such as Adaptive Cruise Control (ACC) and Lane-Keeping Assist System (LKAS). Drivers must steer the vehicle even with the current ACC. LKAS manages the vehicle position within the lane in when the road curvature is not very large. The ability of such systems strongly depends on the(More)
