本文介绍了一种用于改善汽车乘客乘坐舒适性的驾驶员辅助系统的开发。基于主观乘坐舒适性评价的心理物理学实验结果，以汽车纵向加速度和急动度为解释变量，建立了评价乘坐舒适性指数（RDI）的多元线性回归模型。为了减少由汽车速度波动引起的乘坐不适，开发了一种基于微机的驾驶辅助系统，该系统评估RDI，并通过视觉和听觉手段将RDI真实的时间通知驾驶员。实验结果表明，该系统能够提高驾驶员的驾驶技能，改善驾驶员的驾驶行为，为驾驶员提供更友好的驾驶操作，提高乘客的乘坐舒适性，从而验证了所提出的驾驶员辅助系统的有效性。
This paper describes the development of a driver assistance system for improving passenger ride comfort of automobiles. Based on results of psychophysical experiments of subjective ride comfort evaluation, a linear multiple regression model that evaluates the ride discomfort index (RDI) is proposed using longitudinal acceleration and jerk of the automobile as explanatory variables. In order to reduce the ride discomfort caused by the velocity fluctuation of an automobile, a microcomputer-based driver assistance system that evaluates the RDI and informs the driver of the RDI in real time by both visual and auditory means is developed. Experiments show that, with the help of the system, a driver can improve his/her driving skills and modify his/her driving behavior to provide passenger-friendly maneuvers and improve passenger ride comfort, thus verify the usefulness of the proposed driver assistance system.
