Elektrobit has announced a significant step towards producing scalable and cost-effective software for the software-defined vehicle (SDV). Designed for peripheral ECUs such as smart sensors and actuators, EB tresos AutoCore Light supports integration into modern zonal architectures and upgrades of existing domain architectures while reducing development complexity and cost.
The shift towards software-defined mobility requires more than just new technology; it demands that automakers align their product strategies with current and future market needs. This includes developing flexible, scalable solutions that can adapt to both minimal and high-volume use cases.
Building on its extensive expertise in automotive embedded software and the proven success of EB tresos AutoCore, Elektrobit introduces a lean and modular software platform designed to meet emerging SDV demands. EB tresos AutoCore Light addresses the specific needs of peripheral ECUs—cost- and resource-optimised microcontrollers built for input/output (I/O) devices, end nodes, smart sensors, and actuators.
Key Features & Benefits of EB tresos AutoCore Light:
- Modular architecture allows code reuse, simplifies system updates, and reduces development time.
- OEMs working on SDVs can leverage EB tresos AutoCore Light for efficient integration of smart sensors and actuators into E/E architectures. The software foundation for zonal ECUs is provided by EB tresos AutoCore and EB zoneo.
- Up to 30 per cent cost reduction in hardware and R&D is possible by consolidating functions into zonal ECUs and designing peripheral ECUs without OEM-specific requirements—based on Elektrobit's internal benchmarks.
- Smaller MCUs can be utilised for peripheral ECUs, resulting in savings on hardware and development costs.
EB tresos AutoCore Light employs signal-based communication—a widely accepted method, without introducing unnecessary complexity. It is ASIL-B ready and CSMS certified, ensuring safety and cybersecurity compliance even on resource-constrained hardware.
The platform also supports tailored extension packages through EB tresos, including protocols such as J1939 and DLT, depending on the available memory footprint (ROM/RAM).
Jagan Rajagopalan, Head of Strategy & Portfolio, Elektrobit Automotive GmbH, commented, "The Software-Defined Vehicle is a complex ecosystem, and EB tresos AutoCore Light offers a smart, efficient entry point for customers aiming to build scalable, future-ready software. Tailored for resource-constrained peripheral ECUs, it breaks away from traditional monolithic architectures with a lightweight, modular design. By building on proven EB tresos AutoCore components, it empowers customers to accelerate development, reduce integration complexity, and confidently scale their SDV strategies."
The first version of EB tresos AutoCore Light is now available on select microcontroller platforms such as Cortex M0+ and M4F, with additional updates expected later in the year.
