Nissan and Honda Agree to Jointly Develop In-Vehicle OS and Other Technologies for Next-Generation SDVs

Nissan Motor and Honda announced on August 31, 2026, that they had agreed to jointly develop the architecture for an in-vehicle OS, middleware, vehicle-control software and other technologies for next-generation SDVs (software-defined vehicles). They aim to apply it to next-generation SDVs from both companies from fiscal 2029 onward.

The key point is that the companies plan to align core elements of next-generation SDVs—from in-vehicle computers to automotive operating systems, middleware and vehicle-control software—under common specifications. By disclosing what areas they plan to standardize, as well as that the effort targets next-generation vehicles from fiscal 2029 onward, they have given development teams working on in-vehicle software design and validation a clearer picture of the collaboration.
