Description of drawings
It is more obvious that the above and other feature of the utility model, character and advantage will become by the description below in conjunction with drawings and Examples, and identical Reference numeral represents identical feature all the time in the accompanying drawings, wherein:
Fig. 1 has disclosed the structural drawing according to the in-vehicle navigation apparatus with real-time road correction of an embodiment of the present utility model.
Embodiment
With reference to shown in Figure 1, the utility model has disclosed a kind of in-vehicle navigation apparatus 100 with real-time road feedback compensation, comprising: traffic information receiving unit 102, navigation arrangement 104, traffic information display module 106, road condition data feedback component 108 and wireless transmit assembly 112.In the embodiment shown in fig. 1, this in-vehicle navigation apparatus 100 also has data encoding assembly 110.
Traffic information receiving unit 102 is from broadcast base station 200 or and data distribution server 202 reception road condition datas.In one embodiment, traffic information receiving unit 102 is served broadcast base station (RDS) 200 or is received road condition data by wireless network from wireless network data publisher server 202 via teledata by radio broadcasting.A kind of common configuration is: broadcast base station 200 uses radio broadcasting RDS to carry out data broadcast and data distribution server 202 offers broadcast base station 200 with servers' data on the one hand, by wireless network, communicate by letter with traffic information receiving unit 102 such as communication networks such as mobile communication 2G, 3G, GRPS on the one hand.Navigation arrangement 104 is connected to traffic information receiving unit 102, and navigation arrangement 104 calculates guidance path according to road condition data, the road data of navigation arrangement 104 output vehicle positions.Navigation arrangement 104 can adopt commercially available navigating instrument to realize.Traffic information display module 106 is connected to traffic information receiving unit 102, and traffic information display module 106 shows from the road condition data of broadcast base station 200 or data distribution server 202 receptions.In one embodiment, navigation arrangement 104 and traffic information display module 106 common display, display shows map, guidance path, figure traffic information and literal traffic information.Navigation arrangement 104 can be adjusted in real time guidance path and show up-to-date guidance path at map according to road condition data.Traffic information, such as block up, the information such as accident shows with literal on the one hand, on map, indicated with graphics mode on the one hand.Road condition data feedback component 108 is connected to navigation arrangement 104 and traffic information display module 106, road condition data feedback component 108 is the collection vehicle service data also, and road condition data feedback component 108 generates the road conditions feedback data according to road data and the vehicle operation data of road condition data, vehicle position.For traffic information, the information that reflects the most intuitively condition of road surface is travel speed, and therefore, the road condition data of broadcast base station 200 issue comprises the data based on travel speed, and is same, the road conditions feedback data also be one based on the data of travel speed.So in one embodiment, the vehicle operation data of road condition data feedback component 108 collections comprises the travel speed of vehicle.Data encoding assembly 110 is connected between road condition data feedback component 108 and the wireless transmit assembly 112,110 pairs of road conditions feedback data codings of data encoding assembly become road conditions feedback data coding the form that is suitable for launching and export encoded road conditions feedback data to wireless transmit assembly 112.Wireless transmit assembly 112 is connected to data encoding assembly 110, and in other embodiment, if usage data encoding pack 110 not, wireless transmit assembly 112 is directly connected to road condition data feedback component 108.Wireless transmit assembly 112 is to data distribution server 202 emission road conditions feedback data, data distribution server 202 calculates according to the road conditions feedback data and judges, update server end road conditions distributing data, and provide server end road condition data after the renewal to broadcast base station 200, thereby data distribution server 202 and broadcast base station 200 can be provided comparatively accurately and the real-time road data, services.In one embodiment, wireless transmit assembly 112 uses cordless communication network to data distribution server 202 emission road conditions feedback data.Such as, wireless transmit assembly 112 uses 2G or 3G mobile communications network to data distribution server 202 emission road conditions feedback data.
This principle of work of in-vehicle navigation apparatus with real-time road feedback compensation is as follows: traffic information receiving unit 102 receives road condition data from broadcast base station 200 in the RDS mode, perhaps receive road condition data by wireless network from data distribution server 202, road condition data is take the data of travel speed as the basis, such as the travel speed that comprises each section road, judge that with this road is to be in state unimpeded, crowded or that block.Traffic information receiving unit 102 offers navigation arrangement 104 and traffic information display module 106 with road condition data, guidance path is planned and shown traffic information at map.If the guidance path of planning can't be avoided highway section crowded or that block again, even perhaps the user does not open the guidance path guide, when vehicle entered into this road conditions highway section, road condition data feedback component 108 started beginning collection vehicle service data, such as the actual travel speed of vehicle so.Navigation arrangement 104 can the output vehicles the real road position, when physical location enters into its road conditions point that receives or section, during such as the highway section of crowded or obstruction, can trigger road condition data feedback component 108 and start working.Road condition data feedback component 108 can record and is calculated the average speed of vehicle in whole crowded or congested link, obtains the travel speed information of a reality.This travel speed information is used as the basis of road conditions feedback data.The road information that has also comprised the physical location of vehicle in the road conditions feedback data so just can access the data value of a up-to-date travel speed in specific road section.The road conditions feedback data sends to data distribution server 202 by wireless transmit assembly 112 after being encoded by data encoding assembly 110, upgraded by 202 pairs of servers' datas of data distribution server, the servers' data after the renewal also is provided for broadcast base station 200.Broadcast base station 200 and data distribution server 202 can be received the up-to-date Real-time Feedback for actual road conditions from end user location like this, calculate and judgement by algorithm, and in the distributing data to should road conditions point or the data in highway section proofread and correct, with guarantee distributing data in real time accurately.Evaluation result shows, when strategic road network in the city had 1000 terminal operatings, the accuracy rate of traffic information was obviously promoted, and when having 10000 terminals, substantially can guarantee the accuracy of traffic information.
Of the present utility model have the in-vehicle navigation apparatus of real-time road feedback compensation based on the RDS pattern, realize that cost is lower, simultaneously, this equipment only calculates during to certain congestion information place and feeds back at Vehicle Driving Cycle, therefore data volume is less, and the performance of hardware device is not had excessive demand.Road conditions feedback by each navigator and upgrading, can Effective Raise RDS pattern in real-time and the accuracy of road condition data.
Above-described embodiment provides to being familiar with the person in the art and realizes or use of the present utility model; those skilled in the art can make various modifications or variation to above-described embodiment and not break away from utility model thought of the present utility model; thereby protection domain of the present utility model do not limit by above-described embodiment, and should be the maximum magnitude that meets the inventive features that claims mention.
