The invention provides a curve coordinate system establishing method and device, and electronic equipment, and relates to the technical field of driving. The method comprises the following steps: firstly determining a lane center line based on a first lane line and a second lane line, then determining a mapping relation between a first transverse distance and an arc length according to the lane center line, and establishing the curve coordinate system on the basis of the mapping relation to determine the relative position relation between the target vehicle and the original vehicle. The method can be suitable for the situation that the boundary line is not parallel to the lane line, and the problem that the error rate of calculation of the position relation between the running vehicle and the target object is high is solved; and the beneficial effects of reducing manual intervention and improving driving safety are achieved.

本发明提供了一种曲线坐标系的建立方法、装置和电子设备，涉及驾驶技术领域，该方法包括：首先基于第一车道线和第二车道线确定车道中心线，然后根据车道中心线确定第一横向距离与弧长之间的映射关系，再基于映射关系建立曲线坐标系，以确定目标车辆与原车辆之间的相对位置关系，可以适用于边界线与车道线不平行的情况，缓解了行驶车辆与目标物之间位置关系计算的错误率较高的问题，实现了降低人工干预、提高驾驶安全性的有益效果。
