Nissan presented the fourth-generation of its Advance Safety Vehicle (known as the ASV-4) which will be used by the Japanese carmaker to test various technologies in preparation for commercial application. Based on the JDM Fuga sedan (Infiniti M in the US), the ASV-4 employs advanced vehicle-to-vehicle communication systems alerting the driver in case of an on-coming vehicle which may not be visible, but poses a potential threat to road safety. -Press release and images after the jump
NISSAN DEVELOPS FOURTH-GENERATION NISSAN ADVANCED SAFETY VEHICLE
- Advanced vehicle-to-vehicle communications to help reduce accidents -
The Nissan ASV-4 warning system employs vehicle-to-vehicle communications to alert the driver to take defensive actions in situations where an on-coming vehicle is not yet visible, but poses a potential threat to road safety. While the system will be tested using real-time navigation information, it currently has some limitations because it is dependent on information received from vehicles equipped with the Nissan navigation system, therefore participating drivers must remain alert to other vehicles on the road that the system is unable to detect. The preventive safety technologies deployed on the Nissan ASV-4 were developed to address specific high-risk scenarios that account for approximately 60%*3 of traffic accidents in
Cumulative data on traffic accidents reveal that most accidents occur within the following circumstances:
- Two vehicle collisions at blind-intersections
- A right-turning vehicle hit by on-coming vehicle from the opposite direction at an intersection
- Broadside of a motorcycle or bicycle by a left-turning vehicle
- Rear-end collision
The driver can both hear and see the warnings issued by the navigation system when a potentially dangerous situation has been identified.
For example, as the vehicle approaches an intersection or attempts a right turn, the system can warn the driver of the potential danger with an on-coming vehicle as it accelerates after a stop, even when the driver fails to notice.
Nissan will participate in Phase Four of the Advanced-Safety Vehicle project an initiative under the Ministry of Land, Infrastructure and Transport. The company is also leading the ITS (Intelligent Transportation System) project in Kanagawa prefecture*4, involving customers’ vehicle participation, where the system is fed traffic data via links to traffic infrastructure (e.g. using beacons). Another on-going project employs telematics via cellular phones to improve traffic flow and reduce traffic congestion. To help reduce vehicle-pedestrian accidents, Nissan has developed an ITS system based on cellular communications between pedestrians and drivers, and is refining its information system to allow the driver to receive an alert on an unseen pedestrian.
Nissan continues to accelerate the development of its advanced ITS-based accident-prevention technologies for commercial application. In
- *1.ASV is a project under the Ministry of Land, Infrastructure and Transport. Nissan has participated in Phase One (1991-1995), Phase Two (1996-2000) and Phase Three (2001-2005) as well as the next Phase Four starting in 2007. The Nissan ASV-4 was developed as Phase Four of this project.
