A speech navigation method of the vehicle's satellite navigation system for the complex cross of road includes inputting the start position and destination to the system by user, choosing the optimal path on a digital navigatino map, receiving GPS signals to determine the current position on said digital map, and speech prompting of the running direction at complex cross when the distance threshold of speech prompting reaches.
Description
Technical field:
The present invention relates to satellite vehicle navigation system, more specifically relate to the phonetic navigation method of satellite vehicle navigation system at complex crossing.
Background technology:
The alleged complex crossing of the present invention is meant at the crossing only points out " left-hand rotation ", " right-hand rotation " to can not determine the crossing that is meant which bar road.The alleged general crossing of the present invention is meant as long as point out " left-hand rotation ", " right-hand rotation " just can correctly guide the crossing of working direction.Along with the civil nature of global satellite positioning and the develop rapidly of auto industry, the exploitation of increasing company vehicular input satellite navigation system, Voice Navigation then is one of essential scheme of each family, on general crossing, guide the direction of advancing with voice suggestion " left-hand rotation ", " right-hand rotation ".But at the crossing of complexity, it is very difficult that Voice Navigation will become, because only prompting " left-hand rotation ", " right-hand rotation " can not determine and be meant which bar road, also just can't navigate.
In general, road cross can be summed up as three classes:
1, regular crossroad
This class crossing is 4 roads and 4 crossings that the road is following of rule, can use " left-hand rotation ", " right-hand rotation " to illustrate easily, as shown in Figure 1.
In Fig. 1, if the path is " B-X-D ", can prompt for " preceding requested in person commentaries on classics ".
2, the crossing of 5 of irregular crossroads and above road
This class crossing intersects to form the crossing by 5 and above road, uses patent " (satellite vehicle navigation system is at the phonetic prompt method of complex crossing " can finish voice instruction under most of situation.As Fig. 2, shown in Figure 3.
In Fig. 2,, can prompt for " the preceding left second road of requesting in person away " if the path is " A-X-B ".
3, complex crossing
In modern urban road is built, be subjected to the restriction of geographical conditions, road becomes increasingly complex, for example at the upper and lower bridge of overpass place, and the perhaps place of bridge up and down of viaduct, even on the broad road that has, often be provided with the auxilliary road of special purpose, these auxilliary roads are almost one with corresponding main stem, as shown in Figure 4, the above-mentioned two kinds of methods of simple use can't have been pointed out clear, can lead to misunderstanding on the contrary.
For example in Fig. 4, if shown in solid line, then can't navigate with the reminding method in 1 and 2 in the path.
Also have a kind of similar complex situations as shown in Figure 5, this situation is when arriving the crossing, and different tracks arrives different directions.
Solution commonly used at present is near these crossings (for example distance is less than 300 meters) time, shows the sketch of an amplification on navascreen, utilizes diagram to tell which bar road the driver should walk.Yet the critical defect of this treating method is:
A) under the situation of Fig. 5, need to gather lane information, greatly increased map and transferred the workload of painting;
B) before complex crossing, the driver is in the car, thereby is difficult to apace to make judgement with actual geographical environment is consistent with the sketch on the screen;
C) at advanced road, overpass inlet or viaduct inlet, the speed of a motor vehicle is often than comparatively fast, and the driver is not free to go to make judgement according to screen, thereby causes sailing into wrong road.
Summary of the invention:
Purpose of the present invention is exactly in order to overcome the above problems, the phonetic navigation method of a kind of satellite vehicle navigation system at complex crossing is provided, it is too many that workload when making navigation with numerical map is increased, again can be at the complex crossing place clear and concise prompting car owner, reduce mistake and sail.
For achieving the above object, the present invention proposes the phonetic navigation method of a kind of satellite vehicle navigation system at complex crossing, it is characterized in that comprising the steps: 1) accept the departure place and the destination-address of user input; 2), select optimal path from origin to destination according to the navigation numerical map of making in advance; 3) by satellite vehicle navigation system receiving world locational system (GPS) signal, determine current position on numerical map; 4) according to selected path, when the distance apart from next complex crossing reached the threshold value of voice suggestion, then the direction that arrives of each track that is identified according to this complex crossing traffic sign of storage was in advance directly utilized voice suggestion " the preceding XX direction of requesting in person away ".
Wherein " XX " can directly adopt the literal of being write on the respective direction traffic sign.If traffic sign is marked with the direction of special track or the arrival of auxilliary road, the direction that each track that then prior this complex crossing traffic sign of storing is identified arrives also comprises the direction that special track or auxilliary road arrive.
When next crossing is not a complex crossing, but during the crossing of regular crossroad or irregular crossroad or five and above road, can simplify processing as follows:
When the distance apart from next regular crossroad reaches the threshold value of voice suggestion, then, directly utilize voice suggestion " left-hand rotation ", " right-hand rotation " or " craspedodrome ", if prompting is not to be illustrated in the place, crossing to keep straight on according to the navigation information at this crossing of storing in advance.
When the distance apart from the crossing of next irregular crossroad or five and above road reaches the threshold value of voice suggestion, then according to the prior navigation information at this crossing of storage, directly utilize voice suggestion " front n rice please be walked right-hand x bar road " or " front n rice please be walked left x bar road " or " front craspedodrome ", if prompting is not to be illustrated in the place, crossing to keep straight on.
Owing to adopted above scheme, solved the difficult problem of satellite vehicle navigation system in the complex crossing voice suggestion.No matter how intricate the crossing is, as long as have label or mark correctly to distinguish on each branch road.Traffic sign is equivalent to each branch road done has gone up label or mark, even the direction that content on the label and driver will go is irrelevant fully, perhaps clear-cut mark is wrong, but it still can be used for distinguishing each branch road as a kind of label or mark, thereby realizes correct navigation directions.This method need not be made the map of amplification, does not transfer the workload of painting map thereby can not increase.
