Software-defined vehicles (SDV) are the future of automotive engineering. Software-based functions and Over-The-Air updates ensure greater security and comfort over the entire life cycle of a vehicle. <\/span>Two previously separate technologies <\/span>seem to be<\/span> the perfect duo in this context: the AUTOSAR standard and the RUST programming language.<\/span> Our blog <\/span>provides<\/span> an insight into why these two technologies can complement each other.\u00a0<\/span><\/span>\u00a0<\/span><\/h3>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

AUTOSAR (AUTomotive Open System ARchitecture)<\/strong> is a globally recognised standard<\/strong> for the development of software architectures<\/strong> in the automotive industry<\/strong>. It offers a modular and scalable platform that enables developers to efficiently create and integrate complex software solutions in embedded systems. AUTOSAR promotes the interoperability and reusability of software components, which shortens development time and reduces costs. Expleo is a long-standing partner of<\/strong> the AUTOSAR consortium and has been involved as<\/strong> a Premium Partner since 2023<\/strong>. As such, we actively support the further development of the AUTOSAR standard with our own expertise and employees. Among other things, we are working in the Safety Working Group on how RUST can be used in future for safety-relevant embedded software in the AUTOSAR environment.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

RUST is an <\/span>open-source<\/span> programming language <\/span>characterised<\/span> by its <\/span><\/strong><\/span>safety, <\/span>speed<\/span> and concurrency<\/span><\/span><\/strong>.<\/strong> Developed by Mozilla Research, it aims to <\/span><\/span>solve some of the most common problems<\/span><\/span> that can occur in traditional programming languages such as C and C++. These include memory errors and data races, which offer attackers potential gateways. <\/span><\/span>RUST is currently used in many operating systems, but also in IoT projects.<\/span><\/span> RUST is still being <\/span>trial<\/span>l<\/span>ed<\/span> for a broad roll-out in the automotive industry, and <\/span>Expleo<\/span> is also investigating the use of RUST in software development projects<\/span>.\u00a0\u00a0<\/span><\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A key feature of RUST is its strict memory management. Thanks to the concept of <\/span>\u2018<\/span>ownership<\/span>\u2019<\/span> and the associated rules on lifespan and access to data, <\/span><\/span>RUST prevents safety-critical defects<\/span><\/span> such as memory leaks and buffer overflows. These safety mechanisms are particularly <\/span><\/span>important for safety-critical applications in vehicles<\/span><\/span>, where errors can have far-reaching consequences. In addition, RUST offers good support for concurrent programming. Thanks to its safe and efficient handling of threads, developers can implement parallel tasks without the typical risks of data races and deadlocks. <\/span>This is particularly relevant for SDVs that need to process many sensors and systems in parallel with low latencies.<\/span>\u00a0\u00a0<\/span><\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
