| Daihatsu is developing Car Intelligence technologies in order to
ensure the safety and comfort of small cars.
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 consistent 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 with a light application
of the brakes to decelerate gradually. 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 discovery of cars approaching
from the left or right.

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 braking
the vehicle, 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 state of steering wheel
operation.

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.
