Nissan Honda SDV Joint Development to Standardize ECUs and Software

Nissan and Honda Move to Standardize SDV Technologies

Nissan and Honda have entered into a joint development agreement focused on standardizing multiple electronic control units (ECUs) and software for their next-generation software-defined vehicles (SDVs). The Nissan Honda SDV Joint Development initiative is intended to reduce development costs and improve R&D efficiency by creating common technical foundations for both automakers. Under the agreement, Nissan Motor Co Ltd and Honda Motor Co Ltd will jointly establish specifications for core vehicle computing and software technologies, creating a shared development base while allowing each company to continue building on its respective strengths.

ECUs and Software Covered by the Agreement

The agreement covers common specifications for multiple core ECUs within the electrical/electronic (E/E) architecture of next-generation SDVs. The planned standardization also extends to the in-vehicle operating system, key parts of the middleware, and vehicle control software running on these ECUs. The ECUs include high-performance main ECUs, also described as High Performance Computers, that use system-on-chips (SoCs), as well as zone ECUs responsible for overseeing individual areas of the vehicle. These technologies form foundational elements of the software and computing architecture required for next-generation SDVs.

Nissan-Honda SDV Rollout Planned From FY2029

The resulting E/E architecture is planned for application in the next-generation SDVs of both companies starting in fiscal year 2029. By establishing common specifications before deployment, the automakers intend to create a more efficient foundation for future vehicle development. The approach is designed to support faster R&D while reducing duplicated development efforts across foundational ECU and software technologies. The planned FY2029 application therefore represents the next major stage of the collaboration, with the standardized architecture expected to underpin next-generation SDV programs from both Nissan Motor Co Ltd and Honda Motor Co Ltd.

Why Nissan and Honda Are Collaborating on SDV Software

The agreement follows extensive joint studies by Nissan and Honda into potential software collaboration conducted as part of their broader strategic partnership. During these studies, the companies identified the SDV software domain as a priority area because of the rapid pace of technological change and the need to strengthen competitiveness through faster R&D and more efficient investment. Standardizing foundational technologies is intended to allow the automakers to combine engineering expertise and development resources, helping accelerate innovation while creating economies of scale in software and electronic architecture development.

Future Collaboration Areas

Nissan and Honda said they will continue building on their respective strengths while exploring additional opportunities for collaboration. The companies specifically identified carbon neutrality and vehicle safety among the areas that could support further joint efforts. The broader objective is to use collaboration where common technical development can improve efficiency while preserving each company's individual capabilities. The SDV agreement therefore establishes a foundation for deeper cooperation beyond the initial ECU and software standardization work, with future collaboration potentially extending to technologies and initiatives that support both environmental objectives and safer vehicle development.
