About VSS

The Vehicle Signal Specification (VSS) is an initiative by COVESA to define a syntax and a catalog for vehicle signals. The source code and releases can be found in the VSS github repository.

Supported datatypes

The following is a list of VSS supported built-in datatypes:

Name Type Min Max
