The automotive industry is transforming rapidly, with software-defined vehicles (SDVs) leading the charge. Vector is playing a pivotal role in this transition through its innovative Microsar IO platform. Tailored for low-cost, resource-limited microcontrollers, this platform streamlines the development process of compact mechatronic electronic control units (ECUs) and is well-suited for various automotive subsystems, including advanced safety features and infotainment systems.
Microsar IO sets a new standard in the creation of SDVs, made possible by collaboration with Infineon. By embedding a Hardware Abstraction Layer (HAL) specification for Infineon’s PSOC 4 HV controllers, Microsar IO simplifies hardware management at the mechatronic layer.
Its lightweight and efficient design makes it ideal for applications in critical automotive areas like battery management systems, parking sensors, and HVAC systems. For instance, reducing response time in battery management by 20% through effective resource allocation exemplifies the efficiency of Microsar IO, ensuring minimal resource consumption while maximizing cost-effectiveness.
A standout feature of Microsar IO is its ability to offload complex OEM-specific tasks to companion ECUs. This design choice allows for smoother integration into the vehicle's network, enhancing performance without straining primary ECUs.
The platform streamlines the integration with higher system layers, including cutting-edge compute modules and zonal controllers. This abstraction not only boosts functionality but also clarifies the development process. An example can be seen in how vehicle manufacturers achieved a 30% reduction in development time by leveraging Microsar IO for these integrations.
Microsar IO is impressively compact, needing only 32k ROM and 8k RAM for its basic setup. This configuration supports essential functions, including the operating system, communication protocols, and software updates—all necessary for reliable performance in SDV applications.
Moreover, the platform seamlessly integrates with the VS Code PlatformIO extension, creating a unified IoT development environment. This single workspace allows developers to manage the entire project lifecycle—from setup to building, downloading, and debugging hardware—enhancing productivity significantly.
Key Benefits of Microsar IO
> Simple development: Easy-to-use framework, simple project setup, and platform IO integration
> Low-cost hardware: Supports low-cost hardware with optimized communication for CAN, LIN, UART and SPI
> Vehicle network integration: Seamlessly integrates with OEM networks via companion ECUs
> Safety and Reliability: Supports ASIL-D use cases with long-term support and maintenance
The Microsar IO platform offers numerous advantages. It simplifies the development process through an intuitive framework, making project setup quicker. The integration with PlatformIO boosts workflow efficiency for engineers, allowing them to focus on innovation rather than administrative tasks.
Support for low-cost hardware is also a strong selling point, especially when optimizing communication protocols like CAN, LIN, UART, and SPI, which are critical for vehicle network operation. The platform is designed for compatibility with various OEM networks, thanks to its robust integration with companion ECUs.
Safety and reliability are core strengths of this framework. Microsar IO supports ASIL-D use cases, ensuring that engineers can create solutions with high safety standards. This commitment to safety translates into a longer maintenance cycle, further establishing Microsar IO as a choice for future-ready automotive engineering.
The newly introduced Hardware Abstraction Layer provides standardized interfaces specifically for microcontrollers with limited memory. This enhancement makes it easier for engineers to integrate new components, allowing them to work effectively without being hindered by hardware constraints.
As the automotive landscape increasingly shifts toward SDVs, Microsar IO presents a comprehensive solution for developing compact mechatronic ECUs. With a strong emphasis on reusability, cost efficiency, and system integration, it becomes a vital asset for engineers navigating this fast-evolving industry.
Vector's Microsar IO represents a significant leap forward in the realm of software-defined vehicles. Its advantages—from low resource requirements to effective OEM integration—enable engineers to craft more efficient, cost-effective automotive subsystems. By combining these features, Microsar IO not only meets modern vehicle development demands but also paves the way for future innovations in the SDV landscape.
