Fields​

HeadPosition.pitch ● Float scalar​

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. @range(min: -90, max: 90)

HeadPosition.pitch.unit ● AngleUnitEnum enum​

HeadPosition.roll ● Float scalar​

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.

HeadPosition.roll.unit ● AngleUnitEnum enum​

HeadPosition.x ● Int16 scalar​

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.

HeadPosition.x.unit ● LengthUnitEnum enum​

HeadPosition.y ● Int16 scalar​

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.

HeadPosition.y.unit ● LengthUnitEnum enum​

HeadPosition.yaw ● Float scalar​

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. @range(min: -180, max: 180)

HeadPosition.yaw.unit ● AngleUnitEnum enum​

HeadPosition.z ● Int16 scalar​

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. Positive values = above center of rear-axle reference point. Negative values = below center of rear-axle reference point.

HeadPosition.z.unit ● LengthUnitEnum enum​
