Telematics Services (1)
Automobile Service Applications (Over 750,000 units in service today)
Private sector services started in 1997 in Japan
“CARWINGS”⇒ NISSAN
・Names of Telematics Service
“InterNAVI PremiumClub”⇒ HONDA
“G-BOOK ALPHA” - “G-BOOK”⇒ TOYOTA, MAZDA, SUBARU, DAIHATSU「G-Link」⇒LEXUS

Telematics Services (2)
G-BOOK ALPHA G-Link
• Standard equipment of “Help Net”, an emergency reporting device
The standard equipment of “Help Net” is used in cases on accident or sudden illness, whereby one can be connected to an exclusive operator at the touch of a button and request an ambulance by speaking into the microphone of the onboard unit.
• Car audio system with a built-in G-DRM (G-Digital Rights Management) for music distribution
On-demand car audio “G-DRM”, a digital protection system for copyrighted works that manages encrypted music data stored on a hard disk.
• Dedicated communication device:“DCM for exclusive use with G-BOOK ALPHA”

Telematics Services (3)
CARWINGS
(Others – under experimentation)• Info-communications system utilizing
road-to-vehicle communications technology for the purpose of reducing collisions at intersections
• Information provision system regarding speeding alerts driver to slow down speed in a School Zone, etc.
• Dynamic route guidance system utilizing probe data to alleviate congestion and provide the fastest route
• To provides Information on Gasoline Prices Based on the location of a moving vehicle, real-time information of the market price of gasoline in neighboring regions, and sales prices at recommended gas stations are displayed on a monitor.
• Operator ServiceThe driver can contact an operator by phone around the clock via a switch and communicate his/her requests. Voice communication with an operator enables the driver to know the settings of the destination for the satellite navigation system, traffic information. Also, the driver can be interconnected to road services toobtain information on the closest hospitals.

Telematics Services (4)
InterNAVI PremiumClub• Floating Car System
When a member’s car is operated in a preset road zone, the time required to drive through the zone is uploaded for the supply of information.In addition, data provision by using satellite images is implemented.
• Congestion Forecast InformationBased on cumulative past data on congestion, changes in road conditions are projected with high accuracy. Taking into account the time required for the vehicle to drive through the area, the least congested route is shown.
• Lane-specific informationRoute guidance is provided taking into consideration the land-specific flow as well.
• Inter-navigation WeatherWeather information that will impact driving is provided.
• Increased Operation Efficiency via Exclusive Communication Cards
6
• Collection and Analysis of Vehicle Operational informationOperational data (fuel consumption, emissions volume of CO2, Nox, PM, location data, driving operational data for the driver) are provided in real time.
• Vehicle Emergency Tracking ServiceA service of ongoing reports on the location of the vehicle in case of emergency, such as car theft.
• Temperature notice serviceA service to notify the person in charge when the temperature of the truck bed deviates from the preset temperature range
Telematics Services (5)
Higher speed and more advanced-function onboard communication modules together with expanded and improved network service environments, etc. are expected to enhance the environment, realizing even faster mobile communications. As a result, an even newer and more convenient telematics industry will be created.
Mimamori-kun (vehicle diagnostic information )⇒ Isuzu

Increased Speed of Mobile Telephones for the Advancement of Telematics
Enhancement of mobile phones and development of new wide area wireless system
Necessity for the Development of Telematics◆Diversification of data to be transmitted and increase in data volumes
◆ With base stations deployed across Japan, reliable communicationis possible
◆ Costs are reasonable, and most popular wireless media◆ Relatively large size data transmission is possible (Especially 3G)
All commercial telematics today use mobile phones as communication media

Feb. – Nov. 2006 Study of technical conditions for MBWA systems by MIC ministerial council
Around end of 2006 Taking into account the council report, MIC will start to develop a draft technical regulation as well as license policy for MBWA systems.
Within 2007 MIC will decide MBWA operators.
