Signal Information

The vehicle signal Vehicle.Occupant.Row1.Middle.HeadPosition is a Branch.

UUID

Each vehicle signal is identified by a Universally Unique Identifier (UUID)

The UUID for Vehicle.Occupant.Row1.Middle.HeadPosition is 9dc77abbb70d520aa95cb96d042f6d17

Children

This vehicle signal is a branch or structure and thus has sub-pages:

  • Vehicle.Occupant.Row1.Middle.HeadPosition.Pitch (Head pitch angle, measured as angle from vehicle sprung mass XY-plane as defined by ISO 23150:2023 to the head X-axis. 0 = Head in normal position. Positive values = Head leaning up. Negative values = Head leaning down.)
  • Vehicle.Occupant.Row1.Middle.HeadPosition.Roll (Head roll angle about the head X-axis (right-hand rule). 0 = Head in normal position. Positive values = Head leaning to the right. Negative values = Head leaning to the left.)
  • Vehicle.Occupant.Row1.Middle.HeadPosition.X (Longitudinal 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 = forward of (first) rear-axle. Negative values = backward of (first) rear-axle.)
  • Vehicle.Occupant.Row1.Middle.HeadPosition.Y (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.)
  • Vehicle.Occupant.Row1.Middle.HeadPosition.Yaw (Head yaw angle, measured from the vehicle sprung mass X-axis as defined by ISO 23150:2023 to the head X-axis, around the vehicle Z-axis (right-hand rule). 0 = Head in normal position. Positive values = Head turned left. Negative values = Head turned right.)
  • Vehicle.Occupant.Row1.Middle.HeadPosition.Z (Height 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.
