Development of a driving-support system for reducing ride discomfort of passenger cars

摘要

This paper describes the development of a driving-support system for reducing ride discomfort of passenger cars. Based on results of psychophysical experiments of ride discomfort evaluation, we investigated ride discomfort caused by speed fluctuations of a passenger car and set a multiple regression model that evaluates the ride discomfort index (RDI) using longitudinal acceleration and jerk of the car as explanatory variables. Using a microcomputer, the system evaluates the RDI and informs the driver of the RDI in real time. With the help of our system, the driver can improve his driving skills and modify his/her driving method to reduce ride discomfort.
