Basic Concepts of Vehicle Packaging
STEP BY STEP PROCESS
STEP 1 : PACKAGE AND DESIGN IDEATION• Loosely sketch out several package concepts based on
the functional objectives.• Include layout of the Occupants, Cargo, Power-train,
Wheels and Fuel.• Also think about the body structure and closures (doors)
and any other special features that may influence the package.
STEP 2 : SET-UP DRIVER’S HEIGHT AND POSTURE• Start by positioning the driver using SAE 95th percentile
manikin.• Establish the heel height from the ground and then the
seating posture.• Consider the ground clearance and underbody
structure when positioning the heel points.• Before setting up the seating posture, think abou the
following : 1) Downward Visibility.2) Command of the road-setting (eye-point from the
ground).
3) Ingress/Egress.4) Aerodynamics.
• Probably the best way to get the driver location close is to look at the existing vehicles with the same attributes and benchmark them.
STEP 3 : SET-UP THE REAR OCCUPANTS• Use the 95th percentile manikin with consideration of leg-
room seating, if appropriate, to give the rear occupants better forward visibility.
• Note that in some coupes and some special cars, 95th percentile manikin will not fit in the rear.
• With both manikins placed, establish a small envelope around them and develop visibility goals.
• Look at the Effective Shoulder-room and Head-room first.• Then look at the up and down angles through the
windshield apertures.
• Any other important relationships to the occupant should be noted.
