  • What's ITS?


Intelligent Transport Systems (ITS) are designed to put advanced information and communications technologies to work making our roads safer, more convenient, and more efficient, while at the same time reducing the burden placed on the environment. Government* is working alongside research institutions and private industry to make ITS a reality by collaborating on a variety of associated projects.


* Four ministries are involved with ITS initiatives: the National Police Agency; the Ministry of Internal Affairs and Telecommunications; the Ministry of Economy, Trade and Industry; and the Ministry of Land, Infrastructure and Transport.




Car Intelligence


The Adaptive Cruise Control system tracks the vehicle in front of the driver, eliminating the need to continuously operate the accelerator. The Pre-Crash Safety feature issues a warning in the event of an impending collision and automatically applies the vehicle's brakes if the driver does not respond in time to avoid the hazard. Daihatsu is committed to developing technology to ensure that small cars are as safe as they are comfortable.





Radar Cruise Control


This innovative system follows the leading vehicle at a suitable and constant distance. Operational at speeds ranging from around 45 to 100 kilometers an hour, radar cruise control helps reduce the load on highway drivers. As the leading vehicle slows, the system responds automatically by decelerating gradually with a light application of the brakes In the event that it cannot maintain a safe following distance, the system issues a warning to notify the driver of the impending hazard.




Blind Corner Monitor


This system uses a camera mounted on the front of the vehicle to monitor the driver's blind spots at intersections with poor visibility, helping to speed the detectin of cars approaching from the left or right.

Currently Developing Technologies



Pre-Crash Safety

The most common type of accident is the rear-end collision, most of which are caused when drivers take their eyes off the road or fall asleep at the wheel. The Pre-Crash Safety System provides an effective way to avoid this type of accident.


（1）
When the vehicle is about to collide with the car in front, the system notifies the driver of the impending hazard by issuing a warning.



（2）
If the driver responds by applying the brakes, the

system provides brake assist to help the driver depress the brake pedal.





（3）
If for some reason the driver is unable to depress the brake pedal, the system applies the brakes automatically to decrease the speed at which the collision will occur while pre-tensioning vehicle seatbelts to limit injuries to the driver and passengers.






Daihatsu is developing sensor fusion technology to help make this system a reality. Sensor fusion is designed to improve the recognition of leading vehicles and refers to the combination of laser radar's advanced range measurement with the outstanding pattern recognition capabilities offered by image processing.This technology allows drivers to perceive hazards more quickly and accurately.


Full speed Range Adaptive Cruise Control System with Brake Control

An application of radar cruise control, this system allows a car to track the vehicle in front of it at all speeds, including when stationary. Daihatsu is working to provide a more pleasant driving experience by analyzing how drivers speed up, slow down, and maintain distance between themselves and leading vehicles based on the driving environment. This information is then incorporated into vehicle control programs.



Lane Departure Warning System

This system issues a warning when a driver begins to deviate from the proper lane as a result of taking his or her eyes off the road or falling asleep at the wheel. It then assists steering action as the driver works to take corrective action. In addition to lane recognition technology, Daihatsu is developing technology to detect weaving from the way the steering wheel is operated.


Weaving detected by monitoring lane marker position and steering wheel operation



Creating theFuture Technologies


Road Infrastructure Cooperated system(Advanced Cruise-Assists Highway System)


This system aims to prevent accidents by allowing vehicles to communicate with road-related infrastructure. While all of these sophisticated ITS have great promise, this system is expected to see the earliest introduction of all.

Driver Assistance Systems With Information Exchange(Inter-Vehicle Communications)


This system helps to prevent collisions by allowing vehicles to communicate with each other. It facilitates good judgment and safe driving practices by warning drivers of hazards at intersections with poor visibility and on curvy roads.





Car Multimedia


The evolution of small cars occurring in the information society can be referred to as the "fusion of the car with information technology (IT)." Daihatsu looks at daily car use (town use) from this viewpoint and makes cars easier and more enjoyable to drive. By using the cellular telephone network to connect cars with people, families, and information centers, these technologies make daily car use safer, more pleasant, and more convenient.




Multi - information DVD Navigation System


IT Menu


Compatible with the Internet and e-mail. Transforms cars into information platforms.



Navigation


Helps make driving safer and more pleasant.



Audio functionality


Provides touch panel control for car audio.



Air conditioner operation


Allows simple, single-finger control of air conditioner operation with easy-to-read displays and touch panel operation.



G-BOOK


Daihatsu offers optional onboard terminals (navigation systems) that are compatible with the G-BOOK information service.



The G-BOOK network service consists of a wireless connection between vehicle terminals and the G-BOOK Center. With the ability to access a variety of useful information, drivers gain free use of entertainment content regardless of time and place.


G-BOOK is a trademark of Toyota Motor Corporation.





Transport & Logistics


Daihatsu Operation Support System (DOSS) is an all-purpose system that takes advantage of communications infrastructure and GPS systems. It can be deployed in a variety of settings to meet customer needs.






Car Sharing System

The convenience of the automobile is offset by the CO2 emissions it produces and the traffic congestion it causes. In recent years, trials of car sharing as one means of alleviating these issues have been moving forward throughout Japan. Daihatsu has leveraged the know-how gained from actively participating in these trials to develop a Community-Based Car Sharing System that combines the company's proprietary ITS technology with its core competence of small cars. This innovative system was adopted in April 2004 and is being used by Kansai's large new Saito development. It is also being used in low-emission vehicles and vehicles used in public welfare. Daihatsu is committed to continuing its support for environmentally responsible car sharing.




Public Welfare Transportation Service Support System

The aging of Japan's population is driving a rapid increase in demand for public welfare transportation services, which help transport individuals who have difficulty moving about on their own from their homes to hospitals and other care facilities. Friendship i System, which Daihatsu released in June 2004, automatically sends trip information from the vehicle and allows the fleet to be managed from a computer located in a central office. Through its Friendship Series of public welfare vehicles and its Friendship i system for streamlining public welfare transportation services, Daihatsu is committed to helping build a society where all individuals can experience the pleasure of moving about outside their homes.


When the driver enters his or her user number with either the main unit's keypad or the IC card when getting into or out of the car, the vehicle sends trip information and can print a usage statement on the spot.




Commercial Vehicle Operation Streamlining Support System

Daihatsu has developed Business Support i, a system that links computers in offices and stores with vehicles to allow businesses to monitor vehicle location and work status, to issue instructions and other communications to fleet vehicles in the field. The company is enhancing customer satisfaction by combining its unique small car know-how with ITS technologies to create a simple, inexpensive, and easy-to-use system that is optimized for use in small cars.


Operators can check vehicle locations on an office computer and send messages and handwritten maps to cars in the field.
