Detailed description of the invention
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with attached
Figure and specific embodiment are described in detail.
See Fig. 1, the present invention is directed to existing problem, it is provided that a kind of air navigation aid, including:
Step 101, obtains the starting point of active user, terminal, according to starting point, terminal, generates path planning；
Here, first path planning is generated according to starting point, the terminal of user；Path planning is based on road.
Further, before step 101, the method also includes:
Obtaining the track parameter in every track, track parameter at least includes: direction, track, carriageway type, car
Road limit for width, track limit for height and rotation arrow.
Further, carriageway type at least includes: conventional track, acceleration lane, deceleratuib lane, compound car
Road and tide track.
Step 102, the track ginseng in every track on the vehicle parameter of acquisition active user and path planning
Number, determines the wheeled track of active user；
Here, according to the vehicle parameter of user, length of wagon, body width and type of vehicle etc., determine
The concrete track that user can travel.
Step 103, determines that on wheeled track track change point, track change point at least include front car
Point that number of channels changes and crossing bifurcation point；
Seeing Fig. 5, the specific embodiment 1 of the present invention, wherein N point is a track change point, herein
Number of track-lines increase；The setting of track change point, is to should be noted in order to call user's attention road conditions change
Safety；And if travel direction has change, corresponding track need to be entered: if user is at this crossing on path planning
If travel direction is right-hand rotation, then need to enter right-turn lane in advance.
Step 104, each track change point before reaching home, generate this track to track, front
Shortest path, and each optimal path is shown to user.
Further, at step 104, when the distance of user distance track change point one preset length,
Optimal path is shown to user.
Further, while optimal path is shown to user, also by optimal path voice broadcast to user.
Here, such as 50 meters optimal path need to be shown to when distance track change point one predeterminable range
User；In order to travel conveniently, while the present invention is also provided with showing optimal path, by optimal path voice
Report to user.
Air navigation aid and device that the present invention provides solve data lines in existing navigation and plan that precision is low
Problem, is accurate to track rank by the guiding in path, provides the user the information of more authentic security.
See Fig. 2, step 104, specifically include:
