Embodiment
In the explanation to the preferred embodiments of the present invention, in different accompanying drawings, adopt same or analogous Reference numeral to represent to act on similar element below, wherein omitted explanation the repetition of these elements.
Fig. 1 shows the block scheme of vehicle 100, wherein is provided with guider 110, and it has the embodiment according to data processing equipment 120 of the present invention, to be used to carry out the step according to method of the present invention.Guider 110 also comprises storer 130, has wherein for example stored digital street Figure 135.This numeral street Figure 132 for example comprises the net of the road segment segment in the street that is illustrated between the single geographic position or path.Those highway sections can be associated with the speed limiting information of expression vehicle maximum travel speed that allows on related highway section.At this, this speed limiting information can directly be associated with single highway section among digital street Figure 135 as attribute, perhaps is stored in the storer 130 as independent data 137.(first) speed limiting information 138a that relates to the highway section of vehicle 100 current drivings can be provided to data processing unit 120.
In addition, guider 110 for example comprises mobile transfer unit 140, and it is constructed to the data from computer network (for example from the Internet) are provided to data processing unit 120.Transfer unit 140 can make the transmission of data double-way become possibility, for example by request signal 142 is provided to the server or the computing machine of unshowned computer network or the Internet in Fig. 1, and from the Internet or computer network receive answer signal 143 from this server or computing machine.And will be included in the data of replying in the quotation marks 143 by corresponding interface 144 and offer data processing equipment 120.Be included in data in the answer signal 143 at this and can represent (second) speed limiting information 138b equally about the highway section of vehicle 100 current drivings.Such become possibility from the Internet or from storer 130 requesting computer data in order to make, guider 110 can have positioning unit 145, and it for example adopts satellite navigation system to determine the current geographic position of vehicle 100.The current geographic position of this of vehicle 100 is provided for for example storer 130, transfer unit 140 and/or data processing equipment 120 subsequently.To describe computing machine request speed limiting information 138 below in detail from computer network.
As an alternative or additional possibility, can be at the analysis of the speed limiting information realization data in the highway section of vehicle 100 current drivings, these data are to read in by unidirectional data transfer path (promptly only being used to receive the data transfer passage of data).At this, for example analytic unit 150 can be set, it extracts data from send signal 152, and these data are provided to data processing equipment 120 as speed limiting information.Such analytical equipment 150 for example can extract the TMC data and these data are provided to data processing equipment 120 as other speed limiting information 138c from radio transmit signal.In this case, can adopt the current geographic position of the vehicle of determining by positioning unit 145 100, come from send signal 152, to extract corresponding related data.
In data processing unit 120, it also can be called the data combining unit, can realize the combination of speed limiting information 138.Those speed limiting informations are from different data transfer passages, and for example storer 130, transfer unit 140 or analytic unit 150 read in data processing unit 120.Important aspect of the present invention is from two physically different data processing channels speed limiting information 138 to be read in data processing unit 120.In data processing unit 120 or data combining unit, the speed limiting information 138 that is read in is mutually combined, to produce speed warning message 160.Display device 170 by other interface 165 and guider 110 can be exported to driver 180 with this speed warning message 160.
Below explain in detail about determining the embodiment of speed warning message.In order to realize this embodiment, current navigational system can have more than data source (that is, the data transfer passage) that is used for speed limit only, for example:
-map datum;
-the camera that tests the speed prompting (dangerous point warning) receives this prompting by the data stream of reading from radio signal;
-online camera the prompting of testing the speed, and/or
-TMC report etc.
Should adopt all (or at least several) available data sources, to obtain the speed limit through authenticity examination (as the speed warning message) to the vehicle current location.This speed limit can be provided to the other control systems (for example velograph) of vehicle subsequently, so that carry out further data combination or directly be shown to the driver.Fig. 2 show with for example from TMC data transfer passage 210, the camera that tests the speed prompting 220 and digitally the speed limiting information of Figure 135 offer the synoptic diagram of data combining unit 120.Data combining unit 120 will provide as speed warning message 160 about the information of (through authenticity examination) speed limit.
The first step of data combination can for example be passed through compiler 230 with the 240 pre-combinations of map raw data, promptly obtains map datum 135.This combination can be carried out in the compiler 230 of storer, and it is in this case as the pre-combining unit in the data processing equipment 120.Provide the source that the speed limit (being speed limiting information) for the treatment of each highway section on the travel route at vehicle differently is provided according to data.
Known digital road map or guider provide the source that the attribute of speed limit as street or highway section is provided.When speed limit was controlled, this attribute obtained the information of " verifying ".Whether another of numerical map provides the source to provide speed limit based on regulatory rule (for example 100km/h on interstate highway) or based on traffic indication board.By for example the legal limit restriction being attached to corresponding street part as attribute, can fill the map area that does not comprise speed limit " intelligence ".This may cause illogical speed limit.By analyzing the speed limit in all inlet streets to this highway section, and minimum speed limit is used for this, and " blank zone can realize filling intelligently the speed limit on the highway section that does not have the dispensing rate restriction.For example, as the rotating disk " Niehler Ei " in the exemplary Cologne that illustrates of Fig. 3.The restrictions of rotating disk 310 dispensing rate in raw data 240.All inlets 320 of rotating disk 310 have distributed the speed limit of value for 30km/h.According to the method for " intelligence is filled ", rotating disk " Niehler Ei " 310 same speed limits of distributing 30km/h.
The camera reminder-data 220 that tests the speed comprises for example two classes: the first kind comprises the data that exist on the data carrier that is used to navigate.These data are stored as " limit file " (side file) usually on data carrier, upgrade than map datum 135 faster data so that can realize.The limit file is a data file 137 independently, and itself and map datum 135 are not got in touch.Second class comprises the online camera data that tests the speed (for example corresponding to Fig. 1 speed limiting information 138b), and it is that IMU is crossed the Internet-distributed, so that can remind driver note testing the speed camera or velocity survey point in time.The camera data that tests the speed thus is always more real-time than map datum 135, and should be used for determining speed limit.
The TMC report can comprise the speed limit 138c that determines the highway section.This is particularly useful for the job location.Because by radio 152 issue TMC report, it is real-time with data from the Internet equally, and more real-time than the camera data that tests the speed in the data carrier.Because the TMC report is compared with the camera data that tests the speed from society based on police's data in addition, TMC report or the speed limiting information 138c that draws thus have higher priority than the speed limiting information 138b that is derived from the camera reminder-data that tests the speed.
Based on described real-time property, can priority resolution order, limit information 160 by way of caution with this order from available data source 410 (being the data transfer passage) extraction rate, and can provide the speed limit of being extracted to driver or external control device.For example can realize such priorization according to the form 400 of Fig. 4 by setting up.At this, the speed warning message 160 of the speed warning message that the speed limiting information that is derived from the data transfer passage 410 of the map of being filled by intelligence is drawn is evaluated as has minimum priority P, wherein can assess such speed limiting information, because such information is not based on the foundation of reliable basis with attribute " estimation " E.Speed limiting information from the data transfer passage in the highway section (position 430) of the empirical tests of digital street map can be interpreted as the speed limiting information of next high priority, wherein can be such speed limiting information distributive property " empirical tests " V all the time.Being based on of following below in priority orders adopted the speed limiting information about the numerical map of the information of rule (position 440), it has attribute and " derives " D, and based on the speed limiting information that has adopted about the numerical map of the information of the traffic indication board on current driving highway section (position 450), it has attribute " identification " P.Higher priority is based on the speed limiting information of the camera reminder-data that tests the speed (position 460 in the form) of data carrier, it has attribute " controlled " C, the speed limiting information of following below that is based on the online camera reminder-data that tests the speed (position 470), it has attribute " advance notice " A.Limit priority is assigned to the speed limiting information based on TMC report acquisition TMC, and wherein such speed limiting information has been assigned with attribute " advance notice " A equally.
Should provide the speed limit with limit priority P (promptly having minimum) to driver or external control device.Value in " attribute " row can be further used for informing driver or external control device, and this speed limit is from which kind of data source.
The most complicated data are in conjunction with relating to the camera data that tests the speed.Speed limit is the highway section attribute normally, and the camera data that tests the speed relates to the some attribute in geographic position.Speed limit in the data at first only is applicable to the residing point of the camera that tests the speed.Therefore below adopting as the exemplary algorithm that illustrates in Fig. 5, to realize the combination of point and highway section attribute.
First section S1 speed limit at route 500 is 70km/h, and it for example can be from numerical map and/or for example read or read in the analysis of optics vehicle environmental recognition unit to the traffic board.This speed limit should also offer driver 180 (or external control device) as speed warning message 160.At second section S2, speed limit is 90km/h.Be provided with the test the speed camera 520 or the velocity survey point of when vehicle 100 speed are higher than 80km/h, catching vehicle 100 at the end of second section S2.If the beginning of vehicle 100 section of being positioned at S2 should illustrate the speed limit of 90km/h as the speed warning message to driver 180 (or external control device).520 distances are the scope of D1 if the distance that arrives vehicle 100 tests the speed camera, should show the speed limit (80km/h) of the camera that tests the speed to driver's (or external control device).Should show (or to outside control device transmission) this speed limit, distance is the scope of D2 after vehicle 100 leaves the camera 520 that tests the speed.The speed limit of the 3rd section S3 is shown to driver 180 (or external control device) subsequently.At this, about the data of the speed to be travelled of each maximum can as before as described in read in vehicle 100 or guider 110 by different data transfer passages.
Be included in the form of Fig. 4 and can be used in output as the attribute of speed warning message speed limiting information output, that have limit priority, with source to the restriction of driver's display speed.This for example can by means of on display device 170 to be additional to form figure ground output, as shown in FIG. 6 at other icon icon, that have additional information of maximum permission speed.Figure above for example in Fig. 6 sends the signal of the speed limit of 80km/h to the driver, and it is derived from the Internet.Send the signal of the speed limit of 80km/h in Fig. 6 from top several second icon, this speed limit obtains by the analysis to radio signal (for example TMC information).In Fig. 6, from top several the 3rd figure, send the signal of the speed limit of 80km/h, this speed limit is by obtaining the analysis from the camera data that tests the speed of data-carrier store, the signal that illustrates the speed limit of sending 80km/h in the middle of below wherein among Fig. 6, this speed limit is by obtaining according to the speed limit data of filling to the adjacent highway section intelligence in current driving highway section.If can not determine attribute A, can also export question mark, to inform this situation of driver, so that the driver 180 of vehicle 100 can equally correspondingly understand the speed limit of being exported.
