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 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 criteria of the study. However, the designer may opt to retain the design despite non-compliance with the 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 interaction relative to a vehicle system may be displayed to allow a designer to visually assess compliance with a particular criteria. The occupant representation, vehicle, vehicle system, and geometric representation of the interaction may be rendered and animated in three-dimensions permitting views from various perspectives. The method and system can quickly provide accurate human factors 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 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 study is 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 the human factors criteria of the study.
When a change is made to the occupant orientation, a vehicle system, or any design parameter, regeneration of the entire vehicle design is electronically performed.
During this regeneration step, appropriate relationships between the occupant representation, the vehicle systems, and the vehicle are automatically determined, and vehicle systems are automatically changed according to the revised parameters.
However, the designer may opt to retain a design despite noncompliance with the human factors criteria.
In addition, a geometric representation of occupant interaction with a vehicle system may be displayed to allow a designer to assess compliance with a particular human factors criteria.
The occupant representation, vehicle, vehicle system, and geometric representation of the interaction may be 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.
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
