Abstract
The invention discloses a continuous broadcasting method based on a current road additive attribute. The continuous broadcasting method comprises the following steps: a user uses navigation software to select a place of departure and a destination; the navigation software can figure out an appropriate route; a guide module utilizes the calculated route information to prepare guide information, and then utilizes the results after route calculation to conduct voice broadcast; the current road additive attribute is a part of the guide information; a road inlet mark and a road outlet mark of an intersection are circularly taken out through traversal route information; the road inlet mark of the intersection is utilized to take out the road additive attribute of the entering road from map data, if the road additive attribute is bridge, flyover or tunnel, then the guide point of the intersection is the one with the additive attribute, and if the guide point is not the one with the additive attribute, then voice character strings are directly spliced. The continuous broadcasting method disclosed by the invention has the advantages of improving degree of voice broadcast accuracy, and avoiding the trouble caused by the wrong way as the user cannot understand the broadcast distance accurately.
Description
Technical field
The present invention relates to vehicle mounted guidance field, particularly a kind of continuous broadcasting method according to present road adeditive attribute.
Background technology
Navigation software tradition is generally " after the xxx rice of front, orientation is reported " to the report mode at crossing.And road construction is at present multifarious, traditional report pattern there will be ambiguity at some specific crossing.As shown in Figure 2.When reporting from report position " front xxx rice, turn right ", if user grasps reported distance inaccurate, probably can turn right at the first crossing, place, cause going to the wrong way.
Therefore, need " reporting continuously according to present road adeditive attribute " scheme, by the adeditive attribute of " road A ", carry out distinctive detailed report.
Summary of the invention
The object of the invention is, in order to the crossing pilot point that can determine with special road attribute, to provide corresponding broadcasting method, spy provides a kind of continuous broadcasting method according to present road adeditive attribute.
The invention provides a kind of continuous broadcasting method according to present road adeditive attribute, it is characterized in that: the described continuous broadcasting method according to present road adeditive attribute, user uses navigation software, select departure place, behind destination, navigation software can calculate a suitable route, and bootstrap module utilizes the route information calculated, make guidance information, utilize the result after route calculation to carry out voice broadcast;
Guidance information making is that the route information after utilizing route calculation carries out, and so-called route information essence is exactly the set of series of road mark in map datum.Guidance information is the concept of a broad sense, contains the information that many roads are relevant inside essence;
Present road adeditive attribute is a part for guidance information.By traversal route information, circulation take out one, crossing enter line and one deviate from line.Utilize crossing to enter line, from map datum, take out the road adeditive attribute entering road, if road adeditive attribute is bridge, overhead or tunnel, then judge that the pilot point at this crossing is the pilot point having adeditive attribute.
After decision directed dot information, need to judge whether to meet at present guiding opportunity, namely so-called guiding is specify to drive the distance of crossing pilot point according to style opportunity.GPS information in the moving process of driving in navigating instrument can constantly position, and navigation software can learn the distance of distance crossing pilot point of driving by GPS locating information, can think that The time has come after meeting the distance that style specifies; Style is changeable, such as distance 700 meters, crossing, or the underranges such as 650 meters.
After meeting guiding opportunity, judge that whether this pilot point is the pilot point of adeditive attribute to be had, if it is entered the adeditive attribute of road by crossing, splicing corresponding sound reports serial data.If crossing enters road, adeditive attribute is " bridge ", then character string " front XXX rice goes up bridge afterwards, after lower bridge, guides orientation to report option " is spliced;
XXX rice splices different distances according to the difference of style, and the part that option is guidance information is reported in guiding orientation, and also obtain from map datum, particular content is shown in above-mentioned technical term.
If it is " tunnel " that crossing enters road adeditive attribute, then splice character string " enter/sail into/process of passing through tunnel after the XXX rice of front, go out/roll away from/pass through/tunnel after, guide orientation to report option ";
XXX rice splices different distances according to the difference of style, the part that option is guidance information is reported in guiding orientation, also obtain from map datum, particular content is shown in above-mentioned technical term, enter/sail into/through going out/roll away from/the concrete professional verb such as to pass through also be require according to the style of user and determine.
If crossing enters road, adeditive attribute is " overhead ", then splice character string " front XXX rice goes up overhead afterwards, lower overhead after, guide orientation to report option ";
XXX rice splices different distances according to the difference of style, and the part that option is guidance information is reported in guiding orientation, and also obtain from map datum, particular content is shown in above-mentioned technical term.
If not the pilot point of band adeditive attribute, then direct splicing sound character string " after the xxx rice of front, guides orientation to report option ";
XXX rice splices different distances according to the difference of style, and the part that option is guidance information is reported in guiding orientation, and also obtain from map datum, particular content is shown in above-mentioned technical term.
The voice broadcast character string of synthesis is mainly converted into voice data by voice data translation control and carries out phonetic synthesis by voice broadcast, then utilizes hardware device sounding.
Advantage of the present invention:
Continuous broadcasting method according to present road adeditive attribute of the present invention, improves voice broadcast accuracy.Avoid user to grasp reported distance inaccurate, cause going to the wrong way brought trouble.

Below in conjunction with drawings and the embodiments, the present invention is further detailed explanation:
Fig. 1 is functional flow diagram;
Fig. 2 is specific crossing schematic diagram.
