基于GPS的汽车最小转弯直径测试技术

Measuring technology of minimum turning diameter of automobile based on GPS

简要介绍了现有汽车最小转弯直径测试方法（喷水法）及其不足，提出运用GPS记录汽车行驶轨迹并计算汽车最小转弯半径的设想。利用高斯正算公式将GPS所使用世界大地坐标系转换为平面直角坐标系后再计算出汽车的最小转弯直径。经过试验验证，其测量结果与现有喷水法的测量结果有较好的一致性。

It briefly introduces the test method of minimum turning diameter of automobile （water spraying method） and its deficiency, and puts forward the idea of using GPS to record the running track of automobile and calculate the minimum turning radius of automobile. By using the Gauss positive algorithm, the world geodetic coordinate system of GPS is converted into a rectangular coordinate system, and then the minimum turning diameter of the vehicle is calculated. The experimental results show that the measurement results are in good agreement with those measured by the existing water jet method.
