Vector Informatik GmbH Expands SDV ECU Software Bundle

Vector and SCSK Develop Joint ECU Evaluation Bundle

Vector Informatik GmbH and SCSK Corporation have developed a joint evaluation bundle intended to simplify the development of sensor and actuator applications using Renesas RL78/F2x microcontrollers. The package provides a pre-integrated software foundation designed to reduce integration effort and accelerate initial setup and evaluation. It also targets improved software reusability as automotive electronic control units evolve toward future Software-Defined Vehicle architectures, giving developers a more structured foundation for applications running on microcontrollers with constrained hardware resources.

Integrated Software Foundation Targets Reusable ECU Development

The evaluation bundle combines Vector's MICROSAR IO with SCSK's QINeS-Lite platform and associated drivers. MICROSAR IO is designed as a lightweight software platform for microcontrollers with limited hardware resources, while QINeS-Lite addresses small-scale ECU applications that require capabilities including high-speed communication, over-the-air software updates, cybersecurity, and diagnostics. Bringing these components together in a pre-integrated solution is intended to simplify the software foundation required for sensor and actuator applications and reduce the work involved in integrating individual software components during development and evaluation.

QINeS-Lite Adds Communication, Updates, and Diagnostics

The QINeS-Lite platform provides functions suited to small-scale ECUs where communication speed and software lifecycle capabilities are important requirements. Its supported capabilities include high-speed communication, over-the-air software updates, cybersecurity, and diagnostic functions. These features complement the lightweight approach of MICROSAR IO, allowing the combined software foundation to address application requirements beyond basic microcontroller operation. The integration is particularly relevant to ECU development strategies that seek reusable software components while accommodating the resource limitations associated with Renesas RL78/F2x microcontrollers.

SCSK Drivers Complement MICROSAR IO

SCSK's drivers are based on the open Chiisai specification and provide the hardware abstraction layer required to complement MICROSAR IO. This arrangement separates application-oriented software from the underlying hardware interface, helping establish a more reusable software structure for the target microcontrollers. By combining the drivers with MICROSAR IO and QINeS-Lite, the evaluation bundle provides developers with an integrated starting point rather than requiring each software element to be assembled independently. The approach is intended to simplify setup and evaluation while supporting the development of sensor and actuator applications.

Industry Impact & Outlook

The joint bundle illustrates how reusable software foundations can support the transition toward Software-Defined Vehicle architectures while addressing the practical constraints of small-scale ECUs. For developers working with Renesas RL78/F2x microcontrollers, integrating MICROSAR IO, QINeS-Lite, and Chiisai-based drivers may reduce software integration work and provide a more consistent environment for evaluating communication, diagnostics, cybersecurity, and update capabilities. The immediate significance is therefore focused on development efficiency and software reuse, while further adoption will depend on how effectively the integrated foundation supports specific sensor and actuator ECU requirements.
