Software-defined vehicle (SDV): A technology to watch in 2025

Software-defined vehicle (SDV) technology has been a prominent highlight in the quickly evolving automotive industry. But how much of it is hype, and where is the real and tangible value? CES 2025 in Las Vegas will be an important venue to gauge the actual progress this technology has made with a motto of bringing code on the road.

Elektrobit will demonstrate its cloud-based virtual development, prototyping, testing, and validation platform for digital cockpits and in-vehicle infotainment (IVI) at the show. The company’s SDV solutions encompass AMD’s automotive-grade hardware, Google’s Android Automotive and Gemini AI, Epic Games’ Unreal Engine for 3D rendering, and Here navigation.

Moreover, at CES 2025, Sony Honda Mobility will showcase its AFEELA prototype for electric vehicles (EVs), which employs Elektrobit’s digital cockpit built around a software-defined approach. Elektrobit’s other partners demonstrating their SDV solutions at the show include AWS, Cognizant, dSPACE, Siemens, and Sonatus.

SDV’s 2024 diary

Earlier, in April 2024, leading automotive chipmaker Infineon joined hands with embedded software specialist Green Hills to jointly develop SDV architectures for EV drivetrains. Infineon would combine its microcontroller-based processing platform AURIX TC4x with safety-certified real-time operating system (RTOS) µ-velOSity from Green Hills.

Green Hills has already ported its µ-velOSity RTOS to the AURIX TC4x microcontrollers. The outcome of this collaboration will be safety-critical real-time automotive systems capable of serving SDV designs and features.

Next, Siemens EDA has partnered with Arm and AWS to accelerate the creation of virtual cars in the cloud. The toolmaker has announced the availability of its PAVE360-based solution for automotive digital twin on AWS cloud services.

“The automotive industry is facing disruption from multiple directions, but the greatest potential for growth and new revenue streams is the adoption of the software-defined vehicle,” said Mike Ellow, executive VP of EDA Global Sales, Services and Customer Support at Siemens Digital Industries Software. “The hyper-competitive SDV industry is under immense pressure to quickly react to consumer expectations for new features.”

That’s driving the co-development of parallel hardware and software and the move toward the holistic digital twin, he added. Dipti Vachani, senior VP and GM of Automotive Line of Business at Arm, went a step ahead by saying that the software-defined vehicle is survival for the automotive industry.

Hype or reality

The above recap of 2024 activities shows that a lot is happening in the SDV design space. A recent IDTechEx report titled “Software-Defined Vehicles, Connected Cars, and AI in Cars 2024-2034: Markets, Trends, and Forecasts” claims that the cellular connectivity within SDVs can provide access to Internet of Things (IoT) features such as over-the-air (OTA) updates, personalization, and entertainment options.

It also explains how artificial intelligence (AI) within an SDV solution can work as a digital assistant to communicate and respond to the driver and make interaction more engaging using AI-based visual characters appearing on the dashboard. BMW is already offering a selection of SDV features, including driving assistants and traffic camera information.

At CES 2025, automotive OEMs, Tier 1’s, chip vendors, and software suppliers are expected to present their technology roadmaps for SDV products. This will offer good visibility on how ready the present SDV technology is for the cars of today and tomorrow.
