What is Vehicle Signal Specification?

Vehicle Signal Specification (VSS) is a widely adopted, open data model created to consistently describe and normalize vehicle data (e.g., speed, tire pressure, interior lights, etc.). At its core, it is intended to be simple to understand and usable in a variety of contexts. Think of VSS as a common language to describe vehicle data in the vehicle and the cloud.

Why is VSS needed?

To overcome the challenges caused by fragmented data and meet consumer expectations for digital experiences, a shared understanding of vehicle data and system interfaces is essential, both within the vehicle and across the wider mobility ecosystem. This shared understanding is not optional; it is the foundation for delivering exceptional digital experiences today and in the future.
