 The car of tomorrow is beginning to take shape.
Where is the automobile headed?
Environmentally friendly electric vehicles (EVs) and hybrid cars are growing in popularity at an ever-accelerating rate.
Increasingly budget-conscious drivers are demanding more economical compact vehicles.
As the population ages, safety becomes more and more important.
Sophisticated gasoline-powered cars are becoming remarkably intelligent, and yet ecological questions remain.
Meanwhile the concept of making imaginative use of the energy stored by eco-cars is taking hold.
Considered from the Japanese perspective, the road to the car of tomorrow is revealing a new form.
It is revealing a car that is considerate of the earth and of people, yet still is a pleasure to drive: a car born of the
technologies of Japan, the world’s market leader in the EV and hybrid car categories.
Fujitsu Semiconductor Limited will apply its advanced semiconductor technologies and know-how nurtured over many
years, and its flexible conceptual capabilities, to contribute to the creation of the smart communities of the future,
in which people, cars and entire societies are interconnected.

 Artisans of Japan and
the Future of the Automobile
① Environment

We believe that ecology means consideration for the global environment.

Semiconductors that respond with innovation to the need for early popularization of EVs and hybrid cars
The market for EVs and hybrid cars, which originated in Japan, is expanding rapidly throughout the world. Environmentally
responsive stop-start vehicles powered by internal combustion engines are becoming more readily available, accelerating the
ecological responsiveness of the automobile. The requirements for these eco-cars include not only improved environmental
performance through drive controls and assistance, but also sophisticated innovations for realizing a new energy society by
tapping the energy accumulated on board the vehicles.

In harmony with nature

Drive control (“Active Green”) development activities Driving assistance (“Passive Green”) development activities

 Pursuit of functional beauty Artisans of Japan and
the Future of the Automobile
② Design

We believe that functional beauty reflects consideration for users.

Richly expressive graphic technologies that help drivers achieve ecological driving
An automobile’s functional beauty is more than a matter of stylish external appearance. Functions that give drivers advice on
ecological driving and that support safety have been added to the display systems of EVs and hybrid cars, increasing the
amount of displayed information. Highly developed capabilities for configuring information and displaying it attractively in a
clear manner are essential for the success of these functions.

Realizing richly expressive multi-display systems Step-ahead development in response to evolving

③ Safety

We believe that kindness means watching over the surroundings.

Image-processing technologies that provide visual support contribute to safe driving
Drivers are challenged by many blind spots. They try to drive safely by looking around and by using their rearview and
side-view mirrors. This is insufficient, however. Today, expectations are rising for the Advanced Driver Assistance System
(ADAS)*, which employs multiple cameras mounted on cars as tools to supplement the driver’s vision and contribute to safe driving.

④ Comfort

We believe that comfort comprises a pleasing interaction of time and space

Technologies contributing to realization of a society of seamless mobility connecting people with automobiles
Automobiles transport people in a particular time and space. The key word for making this time and space more comfortable
is connectivity. The emerging era of “seamless mobility” will assure pleasant conditions for car drivers and passengers by
facilitating connections within the car as well as between the car and the ITS infrastructure, the car and the data center, and
the car and the home.
