Embodiment one
As shown in Figure 1, the embodiment of the present invention provides a kind of high-precision electronic digital map navigation method, comprising the following steps:
101. obtaining lane information；The lane information comprises at least one of the following information: lane position, lane length, lane
Width, lane shape, lane wire shaped, lane line position, lane line attribute (such as dotted line, solid line, double amber lines), lane side
To (such as congestion, jogging, unimpeded of, lane attribute (such as bus zone, lorry lane, lane restricted driving information) or lane road conditions
Deng).
Lane position, lane length, lane width, lane shape, lane wire shaped, lane line position, lane line attribute
(such as dotted line, solid line, double amber lines), track direction, lane attribute (such as bus zone, lorry lane, lane restricted driving information)
It can be acquired on the spot by field operation, be obtained using laser point cloud technology, the lane road conditions can be set by Floating Car, networking positioning
It is standby to be acquired and obtained by calculating analysis.
102. obtaining vehicle parameter；The vehicle parameter comprises at least one of the following information: vehicle commander, overall height, car weight or vehicle
Type (such as car, lorry, bus).The input of vehicle parameter information can be obtained by receiving user.
103. determining departure place, destination；Destination can be carried out by receiving the search, input or selection instruction of user
It determines, departure place can be determined as current location, can also be carried out really by receiving the search, input or selection instruction of user
It is fixed.
104. carrying out path planning according to departure place, destination, vehicle parameter, lane information, lane grade navigation road is obtained
Diameter.The prior art generally carries out path planning according to departure place and destination in planning path, acquisition can from departure place to
The route of destination, it is not intended that vehicle parameter.It can be according to paths such as the shortest distance, minimum time, the preferential, minimum charges of high speed
Planning mode obtains different guidance paths, and guidance path does not indicate what lane this walks.The present embodiment is existing
Vehicle parameter and lane information are considered on the basis of technology, can calculate more optimized guidance path.As length of wagon compares
In the case where length, then need to consider that the width in each lane in crossing, guidance path will select suitable lane, otherwise will lead to when turning around
It can not turn.In the case that car category is lorry for another example, then guidance path recommends the lane of lorry traveling.Automobile needs to turn
Xiang Shi, guidance path recommend the lane for meeting steering condition.Road conditions with each lane of a road section are likely to be at different conditions, such as
Left turn lane congestion, and Through Lane is unimpeded, then can be according to lane road conditions in path planning the case where, avoid the vehicle of congestion
A more reasonable guidance path is planned in road.
105. carrying out lane grade navigation according to the guidance path.The lane grade navigation can be voice mode, can also
In a manner of being to show.Voice mode such as " 200 meters of front, come in enters left turn lane, and left-hand rotation passage is unimpeded " etc..Display then can be with
It is shown on navigation interface with text or graphics mode.
Embodiment two
The embodiment of the present invention also provides a kind of high-precision electronic digital map navigation device, comprising:
Input unit 201, for receiving the operational order of user.
Information call unit 202, for calling lane information and vehicle parameter.The vehicle parameter passes through input unit
201 by user be input and stored in the navigation device or in the server of navigation device communication connection, the vehicle parameter
Comprise at least one of the following information: vehicle commander, overall height, car weight or type of vehicle (such as car, lorry, bus).The lane
Information by high-precision electronic mapping service provider be stored in advance in the navigation device or with the navigation device communication connection
Server in, the lane information comprises at least one of the following information: lane position, lane length, lane width, lane shape
Shape, lane wire shaped, lane line position, lane line attribute (such as dotted line, solid line, double amber lines), track direction, lane attribute
(such as bus zone, lorry lane, lane restricted driving information) or lane road conditions (such as congestion, jogging, unimpeded).Lane position,
Lane length, lane width, lane shape, lane wire shaped, lane line position, lane line attribute (such as dotted line, solid line, double Huangs
Line etc.), track direction, lane attribute (such as bus zone, lorry lane, lane restricted driving information) can be adopted on the spot by field operation
Collection is obtained using laser point cloud technology, and the lane road conditions can be acquired and be passed through by Floating Car, networking positioning device
Analysis is calculated to obtain.
Departure place, destination determination unit 203, for determining departure place, destination；Destination can pass through input unit
Search, input or the selection instruction of 201 reception users is determined, and departure place can be determined as current location, can also pass through
Search, input or the selection instruction that input unit 201 receives user are determined.
Path planning unit 204, departure place and destination for being determined according to departure place, destination determination unit 203,
The lane information and vehicle parameter that information call unit 202 calls carry out path planning, obtain lane grade guidance path.Existing skill
Art generally carries out path planning according to departure place and destination in planning path, and obtaining being capable of road from origin to destination
Line, it is not intended that vehicle parameter.It can be obtained according to path plannings modes such as the shortest distance, minimum time, the preferential, minimum charges of high speed
Different guidance paths is taken, and guidance path does not indicate what lane this walks.The present embodiment is on the basis of the prior art
Upper consideration vehicle parameter and lane information, can calculate more optimized guidance path.As length of wagon it is long in the case where,
Then need to consider that the width in each lane in crossing, guidance path will select suitable lane when turning around, otherwise will lead to can not turn.Again
Such as in the case that car category is lorry, then guidance path recommends the lane of lorry traveling.When automobile needs to turn to, road of navigating
Diameter recommends the lane for meeting steering condition.Road conditions with each lane of a road section are likely to be at different conditions, for example left turn lane is gathered around
It is stifled, and Through Lane is unimpeded, then can be according to lane road conditions in path planning the case where, avoid the lane of congestion, planning one
The more reasonable guidance path of item.
Navigation elements 205, for carrying out lane grade navigation according to the guidance path.The lane grade navigation can be language
Sound mode is also possible to the mode of display.Voice mode such as " 200 meters of front, come in enters left turn lane, and left-hand rotation passage is unimpeded "
Deng.Display can be then shown on navigation interface with text or graphics mode.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Within the technical scope of the present disclosure, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Subject to enclosing.
