Concept of Driver Assistance The ASV Project of Japan Geneva November 2003 Informal Document No. 20 (131 st WP.29, agenda item 2.4.)

What is ASV ?  ASV = Advanced Safety Vehicle  Vehicles equipped with systems assisting the driver’s safe driving, utilizing the ITS technology Driving assistance ： Providing information, warning, and control  Drastically reducing accidents caused by mis-operations of drivers  ASV project = Promotion of research and development of ASV technologies through the concerted cooperation of the government, academics and industries

Phase 1 ASVPhase 2 ASVPhase 3 ASV Period FY1991-FY1995FY1996-FY2000FY2001-FY2005 Task Verification of technical feasibility Environmental preparations for realization of practical application Technology development; Study of promotion of dissemination Vehicle models Passenger vehicles passenger vehicles, trucks, buses and two-wheeled vehicles  SubjectsVehicles only Vehicles only, Coordination with road infrastructure Vehicles only, Coordination with other vehicles, etc, Coordination with road infrastructure Outline of the ASV Project

Design Principles of ASV 1.Driver Assistance ASV technologies should understand driver’s wills and support their safe driving based on the concept of driver responsibility. 2.Driver Acceptance ASV technologies should be easy to use and be trusted by drivers. This means that a human-machine interface design should be appropriately implemented. 3.Social Acceptance ASV technology-equipped vehicle must operate with unequipped vehicles and pedestrians. Therefore, we must consider how to obtain proper understanding of the public.

“Concept of Driver Assistance“ (for driver load reduction control technologies) 1.The system should act after confirming the will and intention of the driver. 2.The system should assist driver in safety. 3.The system should be checked by the driver at any time. 4.The system should inspire a proper amount of confidence in the driver, not causing him to place too much confidence nor distrust in the system. 5.The system should be overridden by the driver. 6.The system’s control should be smoothly passed over to the driver when the situation goes beyond the range of assistance of the system. 7.The system should not make a negative impact to the traffic environment. 8.There should be mature society to accept the system.

1.The system should act according to the will of the driver or what the driver normally expects in terms of safety. 2.The system should assist driver in safety. 3.The system should be checked by the driver at any time. 4.The system should inspire a proper amount of confidence in the driver, not causing him to place too much confidence nor distrust in the system. 5.The system should be overridden by the driver in the case that the driver operates for more safety. 6.The system’s control should be smoothly passed over to the driver when the situation goes beyond the range of assistance of the system and if a room for operation by the driver is left. 7.The system should not make a negative impact to the traffic environment. 8.There should be mature society to accept the system. “Concept of Driver Assistance“ (for accident avoidance or mitigating control technologies)

Checking process using Concept of Driver Assistance as checking list MLIT checks a new technology for driver assistance through a manufacturer’s technical explanation on the consideration of it’s technology in accordance with “Concept of Driver Assistance.” For carrying the confirmation smoothly, technical guideline may be utilized.

Concept of Driver Assistance & Technical Guideline MLIT checks the design concepts of new technologies using “Concept of Driver Assistance.” If a technology has been confirmed to meet the technical guideline, checking is omitted Based on the result of checking, a technical guideline may be modified or newly defined.
