  SDV: Software Defined Vehicle

Since the Hitachi Group era and with Hitachi's support, Astemo has leveraged its competitive software development capabilities to enhance competitiveness in fields that include electrification, advanced driver assistance systems/autonomous driving, and advanced chassis. Anticipating an era where SDVs evolve mobility to become more flexible and convenient, it has not only advanced development in the In-Car domain, but also strengthened its capabilities in the Out-Car domain, which includes cloud engineering. This is achieved by integrating software and hardware, all the while ensuring safety.

Going forward, through enhanced collaboration with Honda, we will further leverage the automaker’s expertise in development. In addition, with Hitachi's digital technology-focused support, we aim to build a framework that advances AI and software development—essential for the SDV age—with high efficiency and speed, accelerating all initiatives to maximize the value we deliver to every customer.

As a system solution provider that offers not just individual components but software-defined integrated vehicle systems, Astemo aims to be a leading company that drives electrification and AI-driven intelligence of mobility in the SDV age, challenging itself to achieve further growth. It will also focus on sustainable growth and enhancing corporate value more than ever, with an eye towards an IPO.

Astemo will continue to advance technological development that enhances the value of next-generation mobility in the SDV age. Through the provision of advanced mobility solutions by automakers, we will contribute to realizing a sustainable society and enriching people's lives.
