Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, in accompanying drawing, only show part related to the present invention but not entire infrastructure.
Embodiment mono-
The process flow diagram of the air navigation aid that Fig. 1 provides for the embodiment of the present invention one, the present embodiment, applicable to the navigate situation of pathfinding of navigation terminal in Vehicle Driving Cycle process, is particularly applicable to navigation terminal and disconnects the situation of carrying out off-line navigation with being connected of server.The method can be carried out by the guider being configured in vehicle mounted guidance terminal, specifically comprises:
110, determine the initialization path between starting point and terminal.
When vehicle utilizes navigation terminal to carry out pathfinding, first specify starting point and terminal.For example, starting point can be current location, can utilize global position system to determine the position that vehicle is current, and terminal is destination.The embodiment of the present invention is the initialization path that meets in advance predetermined policy according to starting point and one of evaluation of end point, and predetermined policy can be the path of the path of selecting distance the shortest, road conditions optimum or not containing the path of charge station etc.Initialization path can be carried out off-line based on parameters such as diagram datas locally by navigation terminal and determine also to have server to determine online, can consider many factors, for example consider the traffic congestion situation of road or arrange as required some must through place etc.
120, in described initialization path, determine at least one node.
Wherein, node refer to vehicle according to initialization path travel the place of process, the selection mode of node can have multiple, can set difference based on the consideration of different factors and really establish rules.For example, according to node spacing distance, according to the default place that easily occurs branch road etc.Node can be determined by navigation terminal, also can according to multidate information, be determined and return to navigation terminal by server.For instance, node can be determined at once having determined after initialization path, can is also to determine when vehicle departs from initialization path again.
130, if travelled, depart from described initialization path, determine from current location to the subpath described node, as the correction path that returns described initialization path.
In Vehicle Driving Cycle process, vehicle is generally to travel according to predetermined initialization path, but vehicle may depart from this initialization path for some reason, when vehicle has departed from initialization path, navigation terminal generally all has the function in the path of reruning, because terminal is determined, so navigation terminal can recalculate a path that can arrive this terminal according to local map datum, but the existing Path Method of reruning is not considered any traffic information, just calculate a path that can arrive in theory this terminal, and owing to may have more path from current location to terminal, its calculated amount may excessively cause computing time longer, and the air navigation aid that the embodiment of the present invention provides is when vehicle has departed from initialization path, the subpath of searching from current location to described node is as revising path, its objective is that guided vehicle gets back in described initialization path.Finding the operation in correction path can be found by navigation terminal off-line, also can be found online by server, then definite correction path is sent to navigation terminal.
Because vehicle has generally departed from after initialization path, its distance of travelling can be not excessive, so getting back to the subpath of described node can be not long yet, deviation position and described internodal path can be not too much yet, so the air navigation aid that the embodiment of the present invention provides is reruned whole piece path to be reduced to subpath calculating, has reduced the calculated amount of programme path again.
On the basis of technique scheme, the operation of determining the initialization path between starting point and terminal is preferably definite online by server, so comprehensively some dynamic traffic informations, the information such as such as congestion in road situation, roadblock, current traffic control, thereby the path optimizing of acquisition running cost minimum.Therefore, a kind of preferred implementation of this operation can be reception server according to dynamic information and historical wheelpath the initialization path between starting point and the terminal of line computation.
For instance, determine in the operation of at least one node in described initialization path, a kind of optimal way can be to select intersection place in initialization path or distance Along ent as described node.
For instance, described node is the place that vehicle will pass through while travelling according to initialization path, and the effect of node is in order to determine subpath, is the intersection point of subpath and initialization path, so node can be the point of crossing of road, such as crossing, road entrance or outlet etc.Again for instance, if while having long one section of road not exist with the point of crossing of other road in initialization path, number of nodes in initialization path will be less so, finding subpath will be restricted, so can also initialization path be carried out to decile according to the length of distance when determining node, be divided into the path that multiple path lengths are identical, using Along ent as described node, can provide more selection for finding subpath, thereby find optimal subpath as revising path.
