弯道半径

自动驾驶车辆局部路径规划中的弯道半径的估算

An estimate of the radius of a crooked road for the local trajectories planning of autonomous vehicles

基于此问题，本文提出使用一些先验知识（道路宽度和弯道半径等）来加强图像处理的准确性。

To work with this problem , we propose to use some prior knowledge ( the road width and curve radius , etc. ) to enhance the accuracy of image processing .

考察分析了行驶速度、质心高度、行驶弯道半径等，对动态垂直载荷作用下高速车辆行驶稳定性的影响。

In the end , an influence of some characteristics , such as driving speed , position of mass center , turning radius , on the driving stability of high speed vehicle with dynamic vertical load is studied .

山区高等级公路由于地形、地质和气候条件因素的制约，设计标准较低，弯道半径、纵坡坡度、路面情况、道路线形综合协调等很难满足车辆的快速、安全、舒适运行。

Climate , the lower designed standard , the radius of curve lane , the gradient of vertical slope as well as the condition of the road surface , it 's hard for the driver to drive fast , safely and comfortably in the high grade road in mountain area .

该U-型通道的横截面为50mm×50mm，弯道的平均半径Rc与通道的水利直径D的比值为0.65，旋转轴与弯道的曲率轴线平行。

The U bend duct has a cross section of 50 mm × 50 mm and a ratio of bend mean radius R c to hydraulic diameter of the duct D of 0.65 . The rotation axis is parallel with the bend axis .
