A computer based system and method for designing an automotive vehicle orients an occupant representation, in electronic form, with respect to a three-dimensional electronic representation of a portion of the vehicle. At least one vehicle system is represented, also in electronic form, with respect to a common reference point, at least one human factors occupant-to-vehicle interaction study is electronically performed to determine occupant interaction with at least one vehicle system, and an outcome of that study is reported to a vehicle designer. The designer then has an option to vary, or alter, the occupant orientation, the location of the vehicle system, or both, so that the design meets a predetermined interaction criteria of the study. However, the designer may opt to retain the design despite non-compliance with the interaction criteria. If a parameter change is made, the system and method automatically rebuild every other effected dimension, and vehicle systems to satisfy the regenerated design are automatically selected from an electronic parts library so that packaging alternatives can be quickly studied. A geometric representation of occupant-to-vehicle interaction relative to a vehicle system may be displayed to allow a designer to visually assess compliance with a particular interaction criteria. The occupant representation, vehicle, vehicle system, and geometric representation of the occupant-to-vehicle interaction may be rendered and animated in three-dimensions permitting views from various perspectives. The method and system can quickly provide accurate human factors occupant-to-vehicle studies for a vehicle design while allowing system packaging flexibility. |

DETAILED DESCRIPTION The present invention overcomes the deficiencies of current vehicle design practice by providing a method and system which can quickly provide accurate human factors interaction studies for a vehicle design while allowing system packaging flexibility.
The computer based system and method of the present invention orients an occupant representation, in electronic form, with respect to a three-dimensional electronic representation of a portion of the vehicle.
At least one vehicle system is represented, also in electronic form, with respect to a common reference point.
At least one human factors interaction study is performed to determine occupant interaction with respect to at least one vehicle system, and an outcome of that study is reported to a vehicle designer.
The designer then has an option to vary, or alter, the occupant orientation, the location of the vehicle system, or both, so that the design meets the interaction criteria of the study.
However, the designer may opt to retain the design despite non-compliance with the interaction criteria.
In addition, a geometric representation of occupant interaction relative to a vehicle system may be displayed to allow a designer to visually assess compliance with a particular interaction criteria.
The occupant representation, vehicle, vehicle system, and geometric representation of the occupant interaction may be rendered and animated in three-dimensions permitting views from various perspectives.
An advantage of the present invention is a method and system for vehicle design which considerably reduces vehicle design time and expense.
Another advantage of the present invention is a method and system for vehicle design which can be applied to any vehicle system, device, or component which interacts with a vehicle occupant.
Yet another advantage of the present invention is a method and system which can be applied to any vehicle system which interacts with an occupant.
Still another advantage of the present invention is a vehicle design method and system which allows study of vehicle packaging feasibility early in the design process
