Driver Posture Prediction Optimization Dialog Box

The Posture Prediction Generator dialog box starts a sequence of posture predictions from the parameter sizes that are defined in the dialog box.

To access the dialog box, select Optimize Driver Posture Prediction and the package. This is available only for Driver and not for passengers. If the posture prediction node assigned to a passenger selects, or the posture prediction does not assign to a driver, an error message appears, and the command exits.

This page discusses:

Invariants

The inputs of the posture prediction that not modify by this command.

Variants

The inputs of the posture prediction that can modify for an experiment. Example, the group size for certain parameters, additional filters like reachability, postural score, collision test, and others.

Seat Ratio
Activate the editor by clicking the mouse inside the floor geometry editor and then select the geometry. Only the plane selection is enable for selection of floor geometry.
SW tilt ratio
Activate the editor by clicking the mouse inside the pedal editor and then select the geometry. The plane selection and surface selection enable for the selection.
SW telescope ratio
Activate the editor by clicking the mouse inside the telescope editor and then select the geometry.
Additional Goals
Additional goals serve as constraint for the group of results generated.
Comfort

Postural score: Postural score uses to sort the results when generate combination clicks. The position with the best postural score for comfort is at the top of the generated list.

Reachability

Pedal test: If defining a pedal test for driver posture prediction. Then the results filter based on the distance between the ball of foot and the pedal center. The lower this distance is the higher it is in the listing. Color coding uses in the combinations panel related to this field. Black: not defined, Red: Failed, Green: Success

Interactions: A manikin assign with a human interaction this executes after running posture prediction. Then the pedal test (if any) and then human interaction. The lower the distance error higher is the ranking for the result.

Collision test

If a roof of the car has been defined in the posture prediction definition, then the test that fails is used to filter out the results.

A combination of the filters applies then the filters apply in this order: Collision, Pedal test, Interaction, and Postural score.

Generate Combinations

Generate Combinations
Click the Generate Combinations to run the experiment over the ranges and inputs specified in the variant and invariant sections.

Combinations

Combinations
All various combinations generate from the inputs and display.
Total number of combinations generated produces the group sizes of seat, tilt, and telescope ratio.

Selecting a row the manikin places it at the predicted posture. Any posture prediction not associated to manikin, a posture does not generate.

All the postures generate do not persist. The postures are available only during the lifecycle of the command. The end of the command all postures flush.
