Elektrobit announced the release of EB tresos AutoCore Light, a software platform designed for peripheral electronic control units (ECUs) in software-defined vehicles. The company unveiled the product on July 9, 2025, positioning it as a solution for cost-effective integration of smart sensors and actuators.
The software targets peripheral ECUs such as smart sensors and actuators that operate on resource-constrained microcontrollers. These components handle input/output functions and serve as end nodes in vehicle electronic architectures. EB tresos AutoCore Light supports integration into modern zonal architectures while enabling upgrades to existing domain architectures.
According to Elektrobit’s internal measurements, the platform can reduce electronic architecture hardware and research and development costs by up to 30% compared to traditional AUTOSAR Basic software implementations. The cost savings stem from the ability to consolidate functions into zonal ECUs and design peripheral ECUs without original equipment manufacturer-specific requirements.
The software uses signal-based communication protocols that are established in the automotive industry. It meets ASIL-B safety standards and carries CSMS certification for cybersecurity management systems. The platform operates on smaller microcontroller units, which contributes to hardware cost reductions.
Jagan Rajagopalan, Head of Strategy & Portfolio at Elektrobit Automotive, described the product as an entry point for companies developing software-defined vehicle strategies. The modular architecture enables code reuse, simplifies software updates, and reduces development time compared to traditional monolithic approaches.
The first version of EB tresos AutoCore Light is available for Cortex M0+, M4F, and similar microcontroller platforms. Elektrobit plans additional updates later in 2025. Customers can expand functionality through extension packages, including J1939 and DLT add-ons, depending on available memory capacity.
Elektrobit, a subsidiary of Continental, specializes in automotive software development. The company has operated in the automotive sector for over 35 years and reports that its software powers more than five billion devices across 600 million vehicles. The company develops solutions for car infrastructure software, connectivity, security, automated driving tools, and user experience applications.
The software-defined vehicle market represents a shift toward vehicles that can receive software updates and new features throughout their operational lifetime. This approach requires electronic architectures that can support remote updates and feature additions while maintaining safety and security standards.
