DYNAMIC RIDE-COMFORT ANALYSIS SYSTEM FOR DETERMINING SUITABLE DRIVING CONDITIONS BY ANALYZING CORRELATION BETWEEN SUBJECTIVE EVALUATION RESULT AND OBJECTIVE EVALUATION RESULT

摘要

PURPOSE: A dynamic ride-comfort analysis system is provided to determine suitable driving conditions by analyzing correlation between a subjective evaluation result and an objective evaluation result. CONSTITUTION: A dynamic ride-comfort analysis system includes a data obtaining part(100), a data processing part, and a data outputting part(600). The data obtaining part(100) obtains a vibration acceleration signal delivered to a human body in a vehicle. The data processing part has an algorithm for substituting a subjective evaluation about a dynamic ride-comfort to an objective evaluation. The data outputting part(600) displays the content and the results of the data obtaining part and the data processing part in real time. Various road surface conditions are extracted from the vibration acceleration signal obtained through the data obtaining part(100). A frequency weighting function is applied to the vibration acceleration signal through the digital filtering.
