In preparation for a
future commercial application, Nissan Motor Co., Ltd.
has announced the development of it’s
fourth-generation Advanced Safety Vehicle, known as the
Based on the Advanced
Safety Vehicle (ASV) Promotion Plan by the Japanese
Ministry of Land, Infrastructure and Transport, the
vehicle is designed to help reduce accidents thanks to
advanced vehicle-to-vehicle communications which enable
vehicles with wireless terminals to communicate with one
another and share information, including location and
Nissan ASV-4 warning system employs
vehicle-to-vehicle communications. The
preventive safety technologies were
developed to address specific high-risk
scenarios. 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.
The ASV-4 was developed
as Phase Four of the project, following Nissan's
previous participations in Phase One (1991-1995), Phase
Two (1996-2000) and Phase Three (2001-2005).
The Nissan ASV-4 is
intended to test various technologies. Its warning
system employs vehicle-to-vehicle communications to
alert drivers 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 tests use
real-time navigation information, the system has
currently some limitations due to its dependency 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% of traffic accidents in Japan (based
on cumulative accidents estimated by Nissan ASV-4

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 is leading the Intelligent
Transport System (ITS) technologies (see also
prevention system) project in Kanagawa prefecture,
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
In Japan, Nissan aims to halve the
number of traffic fatalities or serious injuries
involving Nissan vehicles by 2015 compared with the
level in 1995.
