Rust integration demo for AUTOSAR Classic migration

HighTec EDV-Systeme and Intellias have successfully completed a Rust integration demonstrator for automotive applications within an AUTOSAR Classic environment. This milestone involved combining Rust components with existing C/C++ code, with the support of ecosystem partners like Vector Informatik and utilizing Infineon AURIX microcontrollers as the target platform.

For readers of eeNews Europe, this achievement serves as a practical example of how memory-safe Rust can be integrated into production-oriented AUTOSAR Classic stacks without the need for a complete rewrite. It also sheds light on the potential toolchain and integration challenges that may arise as OEMs and Tier 1s explore incremental migration strategies for software-defined vehicles.

Why Rust Adoption in AUTOSAR Classic is Significant for OEMs

The decision to adopt Rust is rooted in addressing common pain points in embedded automotive software, particularly related to memory safety issues and their implications on cybersecurity, validation efforts, and project timelines. By introducing Rust for selected functions, the project aims to enable early detection of memory safety issues during compilation, potentially reducing the need for extensive late-stage fixes while leveraging existing AUTOSAR Classic investments.

This approach emphasizes a hybrid model, where Rust is added alongside established C/C++ codebases based on technical feasibility. The goal is to gradually expand Rust integration based on engineering team comfort levels with the workflow and tool qualification processes.

Key Components and Integration Strategy

HighTec highlights the availability of a safety-qualified Rust compiler, compliant with ISO 26262 up to ASIL D standards, to complement its automotive-grade C/C++ toolchain for Infineon AURIX MCUs, leveraging LLVM technology. Vector plays a crucial role in providing support for MICROSAR Classic and DaVinci tooling to seamlessly integrate Rust-written application software.

Intellias’ ECU Kit serves as the foundation for the demonstrator, with Rust-based software components seamlessly integrated into the AUTOSAR environment without necessitating changes to the system’s infrastructure. The setup is based on an Infineon AURIX TriCore TC375, connecting to Intellias’ Automotive Technology Platform (IntelliKit) to simulate various vehicle signals.

“Rust presents significant potential for automotive software development that has yet to be fully realized. Through collaborations with ecosystem partners like HighTec, Infineon, and Vector, we aim to assist customers in efficiently migrating to Rust within an AUTOSAR Classic environment, leading to immediate cost savings,” stated a representative from Intellias.

Both companies are gearing up to showcase related demonstrations at CES 2026 in Las Vegas, with HighTec stationed in Infineon’s Demo Room W307 and Intellias occupying LVCC West Hall Meeting Space #3377.
