Elderly-Oriented Design for the Instrument Panel and Central Console of Intelligent Passengercars

摘要

Based on the elder drivers' perceptual experience, this paper makes a study on the design of human-machine interface of intelligent passenger cars. The study focuseson finding the interior structure which conforms with users' behavioral habits under the background of driving assistance technologies. By means of System Usability Sale (SUS), elder users' perceptual data are collected and the most suited interior structure (p < 0.001) will be clarified according to the Analysis of Variance (ANOVA) of the SUS scores. The cross-section shape of the instrument also influenced the in-vehicle interactive performance. Based on Analytic Hierarchy Process (AHP), the shape of upright is given the highest weight. In order to make designs for central console, arc-cotangent function is used to calculate the tilt angle of the line connecting the upper edge of the instrument panel and the transmission lever, and it can be known that a tilt angle of about 48° is preferred by senior people. Following the basic in-vehicle dimension parameters, an instrument panel and central console design is proposed.
