Contributing Factors for Mode Awareness of a Vehicle with a Low-Speed Range and a High-Speed Range Acc Systems

Abstract

This paper tries to clarify contributing factors to achieving driver's mode awareness while he or she is driving a vehicle with a low-speed range and a high-speed range Adaptive Cruise Control (ACC) systems. We investigate the following three probable factors: (1) control logic for a low-speed range ACC when it loses sight of the target vehicle to follow, (2) previous acquaintance with the high-speed range ACC, and (3) control mode utilized more frequently. An experiment has been conducted with a fixed-based driving simulator to investigate effects of these factors on the driver's mode awareness.
