A method for detecting a pressure for the determination of the comfort of vehicle seats

摘要

A quantitative method of mapping of an automotive seat for prediction of seat comfort includes connecting a computer for storing and displaying pressure maps produced from a pressure mapping system. The pressure mapping system includes a map placed on the seat comprising an array of resistive elements connected to a data acquisition board and utilizing pressure mapping software. A force exerted on the mat changes the resistance of the elements which are sent to the data acquisition board and converted to an array of pressure values by the software to define a pressure map. A plurality of different pressure maps are generated by different forces exerted on the seat, normalized with a common reference pressure map and stored in memory. The normalized pressure map data is then averaged and processed through a comfort analysis or prediction step which compares the averaged pressure map to the reference pressure map. The results are displayed based on a ratio difference between the averaged pressure map and the reference pressure map to quantify seat comfort. The results are rated based on total pressure loading, percent pressure loading of specified delineated areas on the seat, percent point pressures and pressure map gradient loading.
