The HAL4SDV Playground continues to expand with two new demos showcasing how open-source technologies and standardized vehicle data can enable more intelligent, personalized and connected experiences in software-defined vehicles.

The newly available CarMate and Passenger Welcome Sequence (BYOD) demos explore different aspects of the software-defined vehicle ecosystem – from AI-powered interaction with vehicle data to personalized experiences involving connected personal devices.

CarMate: An AI-Powered In-Vehicle Companion

CarMate is an AI-powered in-vehicle companion built using various Eclipse Software Defined Vehicle open-source tools, which provide key capabilities for vehicle data access, communication and service integration. At the core of the demo is the Vehicle Signal Specification (VSS), a standardized data model for describing vehicle signals. By using VSS, CarMate enables Large Language Models (LLMs) to access and understand vehicle signals together with relevant environmental information. This makes it possible for drivers to interact with vehicle data through natural voice communication. Instead of navigating complex menus or interfaces, users can request real-time information and interact with vehicle functions in a more intuitive and human-centered way.

The demo illustrates how standardized vehicle data, open-source SDV technologies and generative AI can be combined to explore new approaches to the in-vehicle user experience.

Passenger Welcome Sequence: Personalization Through BYOD

The second new demo, Passenger Welcome Sequence (BYOD), demonstrates how a software-defined vehicle can create a personalized welcome experience while seamlessly integrating external personal devices. When the driver approaches the vehicle, a coordinated sequence of actions can be initiated – for example, opening the door, switching on ambient lighting, adjusting the driver's seat and interacting with connected personal devices.

Once again, Vehicle Signal Specification (VSS) plays an important role. It provides a common data model for both vehicle functions and connected personal devices, allowing them to be accessed and coordinated in a standardized way.

The Bring-Your-Own-Device (BYOD) approach extends the digital vehicle experience beyond built-in vehicle functions. By enabling personal devices to become part of the overall experience, the demo highlights new possibilities for personalization and interaction across the broader software-defined vehicle ecosystem.

Explore the Demos in the HAL4SDV Playground

Both demos provide practical examples of how standardized interfaces, open-source software and emerging technologies can work together to enable new software-defined vehicle experiences. CarMate demonstrates the potential of combining vehicle data with AI and natural-language interaction, while Passenger Welcome Sequence explores how standardized vehicle and device data can support personalized, connected experiences.

The demos are available to explore in the HAL4SDV Playground, operated by digital.auto.
