Advanced Lane Departure Warning System Set
to Debut
- System Helps Prevent Drivers From Drifting Out of Lanes -
GARDENA, CALIF. (March 31, 2004) ? Infiniti, the luxury division of Nissan
North America, today announced the availability later this year of a new Lane
Departure Warning (LDW) system, which alerts drivers of an unintended movement
of the vehicle out of a designated traffic lane. The new system, which utilizes
a small camera, speed sensor, an indicator and an audible warning buzzer, will
be offered this fall on 2005 models of Infiniti?s popular FX crossover sport
utility vehicle ? the first production application of LDW in North America. The
LDW system will also be available on the next generation M45 performance luxury
sedan, which is scheduled to go on sale in spring 2005 as a 2006 model.
?Studies show that 55% of fatal accidents in the U.S. are caused by lane
departure*,? said Robert Yakushi, Director, Product Safety, Regulatory,
Accessory Quality, Nissan North America, Inc. ?These are caused by various
factors, including driver distraction, inattention or drowsiness. The Lane
Departure Warning system generates a warning to help alert the driver that the
vehicle is about to move out of its lane.?

The Infiniti LDW system is temporarily disabled by driver activation of the
vehicle?s turn signals, which informs the system?s control unit of intended lane
changes. The system also features a manual cancel switch, which allows the
driver to turn the system off when desired. The system automatically resets
when the vehicle is restarted.
System Architecture
The Infiniti Lane Departure System recognizes lane markings through the use of a
small camera mounted behind the rearview mirror. The camera?s signal and the
vehicle?s speed are sent to the system?s advanced microprocessing unit, which
combines the information to calculate both the distance between the vehicle and
the lane marking and the lateral velocity to the lane marking. A judgment is
then made as to whether the vehicle is moving out of the lane (depending on the
distance and lateral velocity to the lane).
If it is determined that the vehicle is leaving the lane, both visual (indicator
light located on the instrument panel) and audible (buzzer) warning signals are
generated, alerting the driver to take corrective action. The system will not
operate if the camera can?t detect the lane markers or if vehicle?s speed is
below 45 miles per hour.
?Some of the typical scenarios where the Lane Departure Warning system will warn
the drivers when they are not giving 100% of their attention to driving and
drift out of their lanes of travel are, for example, adjusting the audio system,
looking at other occupants, searching for addresses or landmarks when driving on
unfamiliar roads, or when concentrating on conversations rather than driving,?
said Yakushi.
The Infiniti Lane Departure Warning system was developed in conjunction with
Valeo SA and Iteris, Inc., the latter that has previously developed LDW systems
for the commercial long-haul truck industry.
About the Infiniti FX and M45
The Infiniti FX premium crossover SUV is available in three models, the FX45
with a standard 315-horsepower 4.5-liter V8 engine and advanced ATESSA ET-S?
all-wheel drive system, the FX35 AWD with 280-horsepower 3.5-liter V6 and the
FX35 RWD with the 3.5-liter V6.
Currently available technology and safety features include an advanced DVD-based
Infiniti Navigation System, Intelligent Key with keyless entry and engine start
system, Tire Pressure Monitor System and RearView monitor. The RearView monitor
projects a view of what?s behind the FX onto the navigation system monitor using
a small camera mounted near the rear license plate (the system operates only
when reverse gear is selected). Also available is Infiniti?s Intelligent Cruise
Control system, which uses the brakes, throttle and laser sensors, to help
maintain a set distance between the FX and a vehicle in front of it.
A preview of the new, second generation 2006 M45 will be available beginning
April 8, 2004 when Infiniti debuts a show car version, the M45 Concept, at the
New York International Auto Show. In addition to the new Lane Departure Warning
system, the production Infiniti M45 will offer an Advanced Air Bag System (AABS)
with dual-stage front supplemental air bags and roof-mounted side-impact curtain
air bags and Brake-Operated Pre-Crash Front Seat Belts.
?Infiniti has long been a leader in utilizing technology for the benefit of the
driving experience ? including our Intelligent Cruise Control, voice-recognition
based navigation and RearView monitor systems.? Said Mark Igo, vice president
and general manger, Infiniti. ?The arrival of Lane Departure Warning is an
important first for Infiniti.?
