*COMPUTE THE OLC FROM A GIVEN VEHICLE VELOCITY CURVE*
=====================================================

Computes the Occupant Load Criterion (OLC) scalar metrics from a vehicle velocity time-history curve. Given free-flight and restraint displacement bounds, it derives the OLC acceleration value used in frontal crash occupant-safety assessments.

     - Required
     - Description
   * - Curve
     - vehicle_velocity
     - vector
     - —
     - 
     - Time-history curve of vehicle velocity (typically mm/ms or m/s vs. time in ms); the primary input from which OLC is derived.
   * - Min Disp
     - min_disp
     - scalar
     - 65
     - 
     - End of free-flight displacement in mm (default 65 mm); defines the lower bound of the OLC integration window.
   * - Max Disp
     - max_disp
     - scalar
     - 300
     - 
     - End of restraint displacement in mm (default 300 mm); defines the upper bound of the OLC integration window.
   * - Scale Factor
     - scale_factor
     - number
     - 1
     - 
     - Multiplicative scale factor applied to the derived acceleration signal before OLC computation (default 1.0; use to convert units or normalise the curve).
