Abstract

This study proposes an experimental evaluation method for vehicle ride quality. In contrast to the conventional method, which is dependent on the fluctuating perceptions of a few experts, the proposed method robustly estimates the ride quality of the target vehicle based on the measured vibration. In addition, the ride quality evaluation in this study is separately performed for two vibration types that have different characteristics of vibration, which derive different perceptions of the human body. Objective measurements and subjective evaluations were simultaneously conducted, and the results of both tests were combined to formulate the ride quality index (RQI) models. Principal component analysis and multiple linear regression analysis were applied to reduce the test procedure complexity and develop the RQI models, respectively. The reliability of the developed models was ensured by the computation of statistical indicators, and the validity of the models was confirmed by an additional verification procedure.
