Toward Preventive ACC Systems against Crashes Due to Another Vehicle's Cut-in

摘要

This paper discusses design of a driver support system for managing risks of crashes due to another vehicle's cut-in. In study 1, we investigate to what extent changing of the target can be automated when a vehicle is cutting in. Experimental results suggest that the autonomous target change may be acceptable for drivers. In study 2, we discuss about reducing driver annoyance with information given from the system if "providing information only" design is employed. The idea is that such information is inhibited when a driver is aware of the situation. A prototype method to detect driver's "preparedness" to hit the brake is shown.
