Abstract
A system and method for classifying the optimization of safety features on a vehicle for a driver of the vehicle based on the height and mass of the driver. The method includes determining a number of basic driver sizes based on driver height and mass and determining a driver'"'"'s seat position for each basic driver height. The method also identifies a set of tunable design variables that are used to adjust the safety features of the vehicle and performs design optimization analysis to identify an optimal design for the vehicle safety features for each of the basic driver sizes. The method then identifies the design from the optimal designs that provides the best performance for randomly selected reference drivers and classifies all drivers into a predetermined number of classifications where each classification represents a particular optimal design.
