CONTRIBUTING FACTORS FOR MODE AWARENESS OF A VEHICLE WITHA LOW-SPEED RANGE AND A HIGH-SPEED RANGE ACC SYSTEMS

摘要

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