The invention provides a method and a device for generating an exit guide line at an expressway intersection, and electronic equipment. The method comprises the steps that when the distance between a vehicle and a target exit intersection reaches a distance threshold value, shape point information from the current position of the vehicle to a target lane where the target exit intersection is located is obtained based on a preset high-precision map; calculating a course angle corresponding to each map point in the target lateral shape point information in the same navigation direction and the lane width of a target lane; offsetting the corresponding map points according to the lane width and the course angle corresponding to each map point to obtain offset point information corresponding to each map point in the target side shape point information; and performing curve fitting according to the offset point information to generate an expressway intersection output guide line. The generated expressway intersection exit guide line can adapt to different bending degrees of the expressway exit intersection under different working conditions, so that stable exit of the vehicle at the expressway intersection is realized, the vehicle exit success rate is improved, and the vehicle use experience of a user is enhanced.

    本发明提供一种高速路口汇出引导线生成方法、装置及电子设备。该方法包括:在车辆与目标汇出路口的距离达到距离阈值时,基于预设高精度地图从车辆的当前位置到目标汇出路口所在目标车道的形点信息,计算与导航方向相同的目标侧形点信息中的每个地图点对应的航向角以及目标车道的车道宽度;根据车道宽度和每个地图点对应的航向角对相应地图点进行偏移,获得目标侧形点信息中的每个地图点对应的偏移点信息;根据偏移点信息进行曲线拟合,生成高速路口汇出引导线。本发明生成的高速路口汇出引导线能够适应高速汇出路口在不同工况下的不同弯曲程度,进而实现车辆在高速路口的稳定汇出,提高车辆汇出成功率,增强用户用车体验。
