Full qualified VSS Path: Vehicle.Occupant.Row2.Middle.HeadPosition.Y
Description: Lateral position of head center measured as mid eye position on X-axis of the vehicle rear-axle coordinate system as defined by ISO 23150:2023 section 3.7.12 Mid eye position refers to the center of a line drawn between the center of the drivers eyes. Positive values = left of rear-axle center. Negative values = right of rear-axle center.

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.
