Model for assessing and grading posture comfort of automotive seats based on Chinese passengers
In this article,in order to explore the posture comfort of automotive seats,a method of assessing and grading is proposed based on the Chinese population coverage and the combination weighting of game theory,for the sagittal-plane posture angle index that affects the comfort of passengers.Firstly,different posture-comfort angles for passengers are worked out with the help of the motion-capture technology,so as to identify the population coverage and calculate the score of each posture-comfort an-gle's evaluation index.Secondly,both the subjective and the objective weights of each index are calculated by means of the G1 method and the entropy-weighting method respectively;the comprehensive optimal weight of each index is obtained based on the combination weighting of game theory.Finally,according to the assessment scores and the optimal weight of each evaluation in-dex,the score for the posture-comfort of automotive seats is calculated through the weighted-average method;the level of the pos-ture comfort is obtained by establishing the 5-level rating standard.According to the difference of the scores for the subjective us-age experience of different automotive seats,it is verified that this classification model is feasible,which provides guidance and basis for the optimal design of the seat-posture adjustment mode for domestic intelligent cockpits.
