Problems solved by technology
When the driver of the vehicle is not familiar with the road conditions and sees the lane reminder at the end of the intersection prompted by the navigation, he is no longer within the safe range of changing lanes, causing the driver to change lanes urgently, and often it is too late to change lanes, or after changing lanes The route is not the optimal route, which greatly increases the possibility of violations or collisions at intersections

Embodiment 1
[0084] Embodiment 1 of the present invention provides a lane maze and a method for creating the same, and a method for recommending a navigation route by using the lane maze, and using the created maze to implement lane-level navigation route recommendation.
[0085] The lane maze provided by Embodiment 1 of the present invention is created according to the obtained high-precision lane information within the specified range of the intersection. The lane maze includes M rows and N columns of maze grids, where M and N are positive integers; identification information is added to each maze grid , which is used to identify the passable lanes and non-lanes of each lane group unit within the specified range of the intersection.
[0086] Wherein, the number of rows and columns of the maze grid is determined according to the number of lane group units within the designated range of the intersection, the number of passable lanes, and lane change information.
[0087] The identification...
Embodiment 2
[0122] Embodiment 2 of the present invention provides a specific implementation process of a lane-level navigation route recommendation method, the process of which is as follows Figure 4 shown, including the following steps:
[0123] Step S301: Obtain high-precision lane information of the road network.
[0124] Obtain the calculation results of high-precision road network and obtain high-precision lane information. The ordinary road network calculation module completes the calculation of ordinary routes.
[0125] Obtain high-precision lane data of the road network, which can include the following:
[0126] Lane-level lane edge information, such as: white solid line, white dashed line, double yellow line, etc.
[0127] Lane-level front and rear lane change information, such as front and rear lane change trend information: the left lane decreases, the left lane increases, etc.
[0128] Lane-level information on the number of lanes, such as how many lanes each lane group u...

Abstract
The invention discloses a lane maze creation and navigation route recommendation method and device. The navigation route recommendation method uses the created lane maze to recommend a navigation route for the vehicle, including: positioning the position of the vehicle in the maze and the maze exit position where the vehicle can pass; The maze path; according to the maze path, the vehicle traffic route is recommended to the user. It can accurately predict the route of vehicles passing through the intersection, realize lane-level route guidance, and guide users to change lanes in time, so that vehicles can pass the intersection smoothly and reduce the possibility of collisions and violations.
Description
technical field [0001] The invention relates to the technical field of navigation, in particular to a method and device for creating a lane maze and recommending a navigation route. Background technique [0002] With the development of navigation technology, navigation is more and more widely used in daily life, and brings great convenience to people's daily travel. In the existing navigation technology, for the lane guidance of the road network, only the lane conditions at the intersection will be displayed, and it will not make a judgment on the continuous change of the lane ahead of the intersection, nor will it accurately deduce the clear direction for the vehicle to pass the intersection smoothly. high-precision lane-level alignment. [0003] Due to the limitation of the driver's field of vision, the lane changes at the intersection are often seen accurately when the lane changes are relatively close to the intersection, such as which lane can go straight, which lane c...
