Technology Introduction

General drive studio

GDSTUDIO is a developing tool to build driving simulation environment for driver via easy creation of road information and scenario with using contents (Visual Database, Sound files).

GDS provides an easy-to-build environment for driving simulators.
Drivers could be exposed to dangerous surroundings while spending high cost and time to experience road conditions.
However, by using driving simulators, drivers can experience various driving environments safely at low cost. It is also possible to collect data for various researches on customers’ specific subjects.

For an instance, it is necessary to study the logic of autonomous driving cars, but due to the its attributes, it can be dangerous to research on real roads.

The GDS provides an editing tool to build road information and to set scenarios of driving situations easily with using contents such as visual database, sound files, etc. The GDS helps drivers experience virtual driving environments effectively with a driving simulator.
