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 truly address the challenge of fragmented data, there must be a common understanding of vehicle data and interfaces between systems, in and out of the vehicle, and across the broader mobility ecosystem. This common understanding of data is fundamental, foundational, and imperative to enabling great current and future digital experiences.

Embracing this need for commonality, standardized vehicle data improves interoperability and eases integration, leading to many scaling opportunities. This saves time and costs, allowing companies to focus on business value creation and differentiating solutions.

Data is a fundamental building block for enabling the Software Defined Vehicle (SDV) and connected vehicles of the future. More precisely, the common data definition as represented in VSS will reduce the many automotive data silos and enable connectivity and collaboration across the mobility data space.
