PERFORMANCE-BASED CLASSIFICATION METHOD AND ALGORITHM FOR PASSENGERS
First Claim
1. A method for classifying a vehicle passenger for optimizing vehicle safety systems and devices for the passenger, said method comprising:
- determining a number of basic passenger sizes based on passenger population of each gender;
determining a number of predetermined passenger seat positions for each basic passenger size;
identifying a set of tunable design variables that are used to adjust the vehicle safety systems and devices;
performing design optimization analysis for identifying basic optimal designs for the vehicle safety systems and devices for each of the basic passenger sizes and the predetermined seat positions;
producing a predetermined number of randomly selected reference passengers and seating positions;
performing analysis for the randomly selected reference passengers in the randomly selected seating positions using the basic optimal designs;
identifying the design from the basic optimal designs that provides the best performance for each of the randomly selected reference passengers in the randomly selected seating position;
classifying all passengers into one of the predetermined number of classifications where each classification represents a particular basic optimal design;
examining the basic optimal designs and their crash performance results to consolidate or reduce the number of basic optimal designs and classifications to a smaller set, if possible; and
setting the vehicle systems and devices for a particular vehicle passenger based on the passenger'"'"'s Body Mass Index and the seating position using the classifications and designs.

Abstract
A system and method for classifying the optimization of safety features on a vehicle for a vehicle passenger based on the passenger seating position and passenger body mass index. The method includes determining a number of basic passenger sizes based on the passenger height and mass and determining a number of passenger seating positions. The method further includes identifying a set of tunable design variables that are used to adjust the vehicle safety features, and performing design optimization analysis for identifying optimal designs, called basic optimal designs, for the vehicle safety features for each of the basic passenger sizes and the predetermined seating positions. The method identifies the design from the basic optimal designs that provides the best performance for randomly selected reference passengers in randomly selected seating positions, and classifies all passengers in their actual seating positions into one of the predetermined number of classifications where each classification represents a particular basic optimal design.
