摘要
汽车的稳定性与其运动学参数(如速度,加速度及转弯半径)及汽车在垂直于路面方向上的位移(称为高度参数)、路面坡度角密切相关,采用传感器测量法很难实时监测汽车的这些参数。本文利用差分全球定位系统(DGPS)Trimble AG114实时地测量了汽车的行驶轨迹、经、纬度、高度参数以及路面坡度角,研究了汽车在垂直于路面方向上的位移与汽车的稳定性的关系,根据汽车的经、纬度坐标利用三点法获得了汽车的转弯半径,为车辆的稳定性监测提供了有效地手段。
The stability of vehicle is affected by its kinematic parameters(velocity,acceleration,and turning radius),the vertical displacement(height parameter),and slope angle.It is difficult to monitor these parameters by using traditional sensors.In this paper,it was described that the realtime measurement of vehicle track,longitudinal and latiludinal coordinates,height,and road slope angle by using the Differential Global Positioning System(DGPS) Trimble AG114 System.The relationship between the height parameter and the stability of vehicle was analyzed and the turning radius was obtained by three-point method based on the longitudinal and latitudinal coordinates.The use of GPS technology provides an effective tool for monitoring the vehicle stability.
