Technological means and effect of taking for reaching predetermined goal of the invention for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, to guider and its embodiment of reminding method, structure, method, step, feature and effect thereof of proposing according to the present invention, be described in detail as follows.
Relevant aforementioned and other technology contents of the present invention, Characteristic can be known and present in the following detailed description coordinating with reference to graphic preferred embodiment.By the explanation of embodiment, when being able to more deeply and concrete understanding for technological means and effect of reaching predetermined object and taking the present invention, but appended graphic be only to provide with reference to the use of explanation, be not used for the present invention to be limited.
First, refer to shown in Fig. 1, it is the exemplary calcspar according to the guider of an embodiment.Guider 100 comprises a data bank 101, in order to store cartographic information, one processing unit 102, be electrically connected on this data bank 101, in order to according to the cartographic information of data bank 101 and implementation and operation, one receiver 103, be electrically connected on this processing unit 103, in order to from multiple satellite received signals, a display 104, is electrically connected on this processing unit 102, in order to show the corresponding cartographic information of at least one part, and a Tip element 105, be electrically connected on this processing unit 102, in order to send voice message and additionally warning.First, receiver 103 is from most satellite picked up signal, with the current position of positioning navigation device 100.Then, processing unit 102 obtains corresponding cartographic information, the potential route of the terminal of being inputted to plan from current position to user from data bank 101.Display 104 shows the corresponding cartographic information of at least one part, the current position that comprises guider 100.Along with the movement of guider 100, be shown in corresponding cartographic information on display 104 also with change.Cartographic information comprises road name, road segments and numbering, road speed limit, various communal facility (such as bridge, tube) and the various terrestrial reference (such as well-known sight-seeing resort, school, station) etc. of between Origin And Destination, passing through.The two-way algorithm of planning potential route is as follows: from current position and terminal simultaneously subtend advance (that is, from starting point to advance towards the direction of terminal, from terminal to advance towards the direction of current position), have if advance to respectively multiple meet impose a condition can direct of travel point fork in the road, can move on by direct of travel along difference respectively, if the subtend route of advancing with relative direction is joined (this place is called " meeting point ") in same place, combine current position to the route of meeting point and meeting point the route to terminal, as a potential route.Therefore, likely obtain many different potential routes.Processing unit 102 calculates the required cost of each the different potential route distance of origin-to-destination route (for example from), and the route that alternative costs are minimum in many potential routes is as optimization route, and the higher route of other costs is called " departing from route " (that is, the route not conforming to optimization route completely).Generally speaking, optimization route is the shortest route of distance from current position to terminal, or estimates the shortest route of arrival time.
In potential route, may have the crossing that user may depart from optimization route.Guider 100 before each crossing, has voice message position, so that can be reminded user by sending voice message in advance.Voice message is to be used to refer to user how to follow optimization route.If, according to the prompting of guider 100, user's travel route can be not different from the optimization route of original planning, that is user can drive to and depart from route.In each voice message position, processing unit 102 calculates and changes road cost, is illustrated in the cost residual quantity between the cost that departs from route of each crossing and the cost of this optimization route.Further, processing unit 102 judges whether Gai Huan road cost is greater than a warning threshold value (distance of for example length-specific), and judged result is delivered to Tip element 105.If judged result Wei Gaihuan road cost is greater than this warning threshold value (importance that represents this prompting is higher), when user arrives voice message position, how Tip element 105 arrives the prompting of optimization route except sending instruction user, and send extra warning, for example LED flash of light, prolongation prompt time, increase prompting number of times, display text warning, vibrations or resonant, if remind user not observe this prompting, significantly off-target route.Changing road cost is greater than the crossing of warning threshold value and is called commit point.If judged result is not more than this warning threshold value (importance that represents this prompting is lower) for this maximum cost residual quantity,, in the time of this voice message position, Tip element 105 only sends indicates user how to arrive the voice message of optimization route.Warning threshold value can be the preset value of guider 100, or can be set voluntarily by user.In the time that user does not set warning threshold value, guider 100 is applied mechanically preset value automatically.
The possible course figure that below refers to Fig. 3 illustrates.Wherein, circle S represents current position, and circle D represents terminal, and V point is voice message position, and N point is crossing.Guider can be cooked up three potential routes by two-way algorithm, that is the route A being made up of point, the route B being made up of solid line and the route C that is made up of dotted line, and the cost of calculated route A, route B, route C respectively.Note, in three routes, the part all identical (being all the represented route of solid line) from starting point S to crossing N.At crossing N, user can determine to take route A, route B or route C.Clearly, route B is the optimization route nearest apart from terminal.Before arriving crossing N, processing unit 102 difference calculated route A and route C are individual not with respect to Huan road cost between route B.Then, relatively else change road cost and this warning threshold value, and judge whether Gai Huan road cost is greater than this warning threshold value.Ruo Gaihuan road cost is not more than this warning threshold value, and Tip element 105 only sends at this voice message position V the voice message how instruction user follows route B.If this maximum cost residual quantity is greater than this warning threshold value, that is crossing N is commit point, and how Tip element 105 follows the voice message of route B except sending instruction user at voice message position V, and sends extra warning.
Warning threshold value can be the preset value of guider 100, or can be set voluntarily by user.In the time that user does not set warning threshold value, guider 100 is applied mechanically preset value automatically.In data bank 101, also comprise many places between current position and terminal (but not necessarily meeting point) position or optimization route of terminal up till now.Processing unit 102, in the time of planning potential route, is reused already present optimization route, need not recalculate already present part at every turn, so can increase calculating usefulness.
Moreover user can increase or change terminal at any time newly, dynamically plan optimization route according to up-to-date terminal in order to processing unit 102, and then recalculate at each voice message position V whether need to send warning.Again, Gai Huan road cost can be stored in data bank 101, if input identical imposing a condition backward, does not need to recalculate Gai Huan road cost.
The advantage of so implementing is: only to importance, extra warning is sent in higher voice message, relatively ignores the voice message that importance is lower, in order to avoid cause user need divert one's attention to receive the puzzlement of too many information.User can differentiate the importance height of voice message easily, then determines according to this whether will observe the voice message of guider.
Refer to shown in Fig. 2, it is according to the process flow diagram of the guider reminding method of one embodiment of the invention.It can be used for example guider 100 as shown in Figure 1, but is not limited only to this.In step 201, after opening guider 100, receiver 103 is from most satellite received signals, and to determine the current position of guider 100, and user inputs terminal.The cartographic information of at least one part correspondence is shown on display 104.Then, in step 202, guider 100 is according to two-way algorithm planning potential route, and the potential route that alternative costs are minimum is optimization route, and the higher potential route of other costs is for departing from route.In step 203, before arriving at next crossing, guider 100 calculates and respectively departs from Huan road cost between route and optimization route, changing road cost table is shown in next crossing, each departs from each cost residual quantity between route and optimization route, and each potential route is at crossing bifurcated.In step 204, guider 100 judges whether Gai Huan road cost is greater than a warning threshold value.If judged result is "Yes", that is next crossing is commit point, and guider 100 enters step 206, can send instruction user how to follow the navigation hint of optimization route and before commit point, send extra warning in voice message position.If judged result is "No", guider 100 enters step 205, only sends indicate user how to follow the navigation hint of optimization route in voice message position.This extra warning can be LED flash of light, extends prompt time, increases prompting number of times, display text warning, vibrations or resonant.Finally, if user arrives at terminal or closes guider 100, i.e. end operation.
In addition, user can input or change terminal (that is getting back to step 201) at any time, and guider 100 can plan optimization route again according to up-to-date terminal, and carries out subsequent step in proper order.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, but not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the method for above-mentioned announcement and technology contents to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
