Honda Motor and Nissan Motor are reportedly considering jointly developing an operating system for software-defined vehicles (SDVs) based on technology developed by Nissan, according to sources. 

The operating system is a core technology for next-generation vehicles, and standardizing it between the two Japanese automakers is expected to improve development efficiency. In SDVs, functions such as autonomous driving can be added or improved through software updates.

Honda and Nissan announced in 2024 that they would explore cooperation in areas including SDVs, batteries and vehicle supply. The companies later entered talks on a potential business integration, but those merger discussions collapsed.

The automakers have continued to examine cooperation on a project-by-project basis. After discussions on standardizing the operating system, they moved toward using technology developed by Nissan, according to sources.
