ATEC Co., Ltd. was established in Nagoya city in 1988 as an independent technology company and expanded its offices in Tokyo, Yokohama, and Osaka.
We have a variety of development experiences in the fields of control software, electrical/electronic systems, and mechanical components for automobile manufacturers and suppliers in Japan.
In 2009, we set up a technology development center in Obu city, Aichi.
On the site, we have developed various high-tech in-vehicle ECUs (Electronic Control Unit) such as ADAS (Advanced Driver Assistance Systems), and AUTOSAR (Automotive Open System Architecture).
The facilities in the center support all development processes from design through to evaluation and verification.
We aim to meet the various demands of our customers by providing technical and educational support as well as development assistance.
