Display device 170 the speed warning message 160 can be exported to driver 180.
The embodiment on determining speed warning message is explained in detail below.In order to realize the embodiment, current navigation
System, which can have, is used for the data source (that is, data transfer passage) of rate limitation more than only one, for example：
- map datum；
- speed detecting camera points out (dangerous spot warning), by the data stream reception read from radio signal the prompting；
- speed detecting camera prompting online, and/or
- TMC reports etc..
Should be using all (or at least several) available data sources, to obtain to current vehicle position through authenticity
The rate limitation (being used as speed warning message) of inspection.The rate limitation is then able to be provided to the other control systems of vehicle
(such as speedometer), to carry out further data combination or to be directly displayed to driver.Fig. 2 show by for example from
It is single that the speed limiting information of TMC data transfers passage 210, speed detecting camera prompting 220 and numerical map 135 is supplied to data to combine
The schematic diagram of member 120.Data combining unit 120 alerts the information on (through authenticity examination) rate limitation as speed
Information 160 is provided.
The first step that data are combined for example can be combined map initial data 240 in advance by compiler 230, that is, obtain ground
Diagram data 135.This combines and can carried out in the compiler 230 of memory, and it is in this case as data processing equipment
Pre- combining unit in 120.The speed that source differently provides each section treated for vehicle on travel route is provided according to data
Degree limitation (i.e. speed limiting information).
Known digital street figure or guider provide source and provide rate limitation as the attribute in street or section.Work as speed
When degree limitation is controlled, this attribute obtains the information of " having verified that ".Whether another offer source of numerical map provides rate limitation
Based on regulatory rule (such as the 100km/h on interstate highway) or based on traffic indication board.For example, by legal limit is limited
Be attached to corresponding street portion as attribute, can " intelligence " fill the map area not comprising rate limitation.This may
Cause illogical rate limitation.By analyzing the rate limitation in all entrance streets to the section, and will be minimum
For being somebody's turn to do, " blank zone can realize the rate limitation on the section intelligently filled and limited without dispensing rate to rate limitation.
For example, such as rotating disk " the Niehler Ei " in Fig. 3 Cologne illustrated.It is no in initial data 240 to be distributed for rotating disk 310
Rate limitation.All entrances 320 of rotating disk 310 are assigned with the rate limitation that value is 30km/h.According to the method for " intelligence filling ",
Rotating disk " the equally distribution 30km/h rate limitations of Niehler Ei " 310.
Map datum 135 is the oldest data in guider.Rate limitation is to be carried long before by data
Supply source collect and may be out-of-date during this period.In addition quality is substantially dependent on the class that data provide source and Data Collection
Type.For example there are four kinds of different rate limitation types in digitally Figure 135.The first kind includes the data filled based on " intelligence "
Rate limitation.Equations of The Second Kind includes the rate limitation that attribute is " having verified that " (i.e. by checking).3rd class is included based on management
The rate limitation of regular (rate limitation of street type).4th class is included by it is determined that the speed that the guideboard of position is limited is limited
System.Further can add attribute in numerical map for each rate limitation, its indicate the rate limitation be related to it is above-mentioned which
Type.
Speed detecting camera prompting data 220 include such as two classes：The first kind is included present on the data medium for navigating
Data.These data are typically stored as " side file " (side file) on the data carrier, enable to realization and compare map
The faster data of data 135 update.Side file is independent data file 137, and it is not in contact with map datum 135.Second
Class includes online speed detecting camera data (such as corresponding to Fig. 1 speed limiting information 138b), and it is to be sent out immediately by internet
Cloth, enable to remind driver to note speed detecting camera or tachometric survey point in time.Thus speed detecting camera data are always
It is more real-time than map datum 135, and should be used to determine rate limitation.
TMC reports can include the rate limitation 138c for determining section.This job location that is particularly suitable for use in.Because passing through nothing
Line electricity 152 issues TMC reports, and it is real-time that it is same with the data from internet, and than the speed detecting camera in data medium
Data are more real-time.Because in addition TMC report be based on police's data, with from society speed detecting camera data compared with, TMC report or
Thus the speed limiting information 138c drawn is higher than pointing out the speed limiting information 138b of data to have from speed detecting camera
Priority.
Based on described real-time property, priority order is can determine, sequentially (is counted from available data source with this
According to transmission channels 410) extraction rate limitation information 160, and institute can be provided to driver or external control device by way of caution
The rate limitation of extraction.Such priorization for example can be realized by setting up the form 400 according to Fig. 4.Here, will be derived from
The speed warning letter of the speed warning message drawn by the speed limiting information of the data transfer passage 410 for the map intelligently filled
160 (positions 420) of breath are evaluated as with minimum priority P, wherein such speed can be assessed with attribute " estimation " E
Restricted information, because such information is not based on reliable Foundation.Can be by the experience from digital street map
The speed limiting information of the data transfer passage in the section (position 430) of card is interpreted as the rate limitation letter of next high priority
Breath, wherein can be all the time such speed limiting information distributive property " empirical tests " V.Below in priority orders and then
Be the speed limiting information based on the numerical map for employing information on management rule (position 440), it has attribute
" deriving " D, and based on the number for employing the information on the traffic indication board on current driving road segment (position 450)
The speed limiting information of word map, it has attribute " identification " P.Higher priority is the speed detecting camera based on data medium
Point out data (position 460 in form) speed limiting information, it has attribute " controlled " C, below followed by based on
The speed limiting information of online speed detecting camera prompting data (position 470), it has attribute " advance notice " A.Limit priority quilt
Distribution obtains TMC speed limiting information to being reported based on TMC, wherein attribute is equally assigned in such speed limiting information
" advance notice " A.
The rate limitation with limit priority P should be provided (i.e. with minimum to driver or external control device
Value).Value in " attribute " row can be further used for informing driver or external control device, and the rate limitation is from which kind of number
According to source.
Most complicated data, which are combined, is related to speed detecting camera data.Rate limitation is typically section attribute, and speed detecting camera number
According to being the point attribute that is related to geographical position.Rate limitation in data is only applicable to the point residing for speed detecting camera first.Therefore adopt
