Summary of the invention
Within this context, this propose a kind of for obtain to arrive in predetermined time interval destination, between departure place and destination, the method for the destination navigation route of vehicle, a kind ofly use the equipment of the method and a kind of corresponding computer program.Each dependent claims and instructions subsequently give favourable design proposal.
Propose a kind of for obtain to arrive in predetermined time interval destination, between departure place and destination, the method for the destination navigation route of vehicle, wherein said method has following steps:
Read in the data about the described time interval arriving described destination;
The travel route using numerical map to determine from described departure place to described destination, wherein so determines described travel route in described deterministic process, namely makes described travel route represent the fastest road between described departure place and described destination;
When checking the traveling on described travel route, time of arrival, whether point was positioned at the described time interval; And
Be positioned at outside the described time interval if described time of arrival puts, then by change and/or the described destination navigation route of interruption acquisition of described travel route, wherein so realize described change and/or interruption, namely to make on described destination navigation route to need from described departure place to the traveling of described destination the running time more grown than the traveling on described travel route and/or unbroken traveling.
Such as can implement the method in conjunction with the guider of vehicle.This destination navigation route such as can be illustrated in the display device of the guider for vehicle driver by color highlightedly.This destination navigation route can be divided into multiple section, and these sections are such as preset in time and/or determined by the street navigation of the such as crossing or branch road in numerical map.In time preset section length can such as with the total length of this destination navigation route for guiding, thus longer destination navigation route can be divided into less and longer section compared to shorter destination navigation route, and departure place and destination can such as be determined by the driver of vehicle and be input in guider.The predetermined time interval can have different length.Therefore the length in the time interval can be positioned at a second scope, is namely short to this time interval substantially to represent time point.Alternatively, the length in the time interval also can be positioned at minute scope long arbitrarily.The driver of such as vehicle can the length of prefixed time interval.The section that travel route can such as be navigated by the street of numerical map forms, and these sections are that vehicle achieves the fastest passing through compared to other possible sections of the street navigation between departure place and destination.Numerical map can be such as stored in vehicle.Inspection step in can such as obtain, whether there is the desired event arriving destination on a time point, before this time point is positioned at the time interval, among or afterwards.If before checking in step and being positioned at the time interval time of arrival determining expectation, then can such as by the change of travel route and/or interrupt obtaining this destination navigation route in the step obtaining this destination navigation route.Traveling such as on this destination navigation route needs a running time, the time point of the arrival destination in this running time restriction time interval.Read in, determine, check and obtaining step can separately by means of suitable algorithm realization.Can in the driving process of vehicle between departure place and destination these steps of at random repeatedly repetition methods, thus the traveling of vehicle can be realized according to current traffic always.
According to a kind of form of implementation, reading in the step about the data in this time interval, also realizing some time rating the latest read in for arriving this destination.This some time rating the latest can limit the end in this time interval.Automatically can preset this point or alternatively preset this some time rating the latest by the driver of vehicle time rating the latest by the method.Therefore driver can according to its hope or given situation correspondingly or be less than the some time of arrival ground point or plan some time of arrival expected with certain safety time buffering time of arrival planning to expect of expectation.
According to another form of implementation, in the step that this reads in about the data in this time interval, also realize the length of reading in this time interval.The reading in of length in this time interval automatically or can be realized according to the input of the driver of vehicle.Advantageously, can according to respective requirement or determine very accurately time of arrival point, or determine some time of arrival of movement in certain margin tolerance.Such as business meeting is dated compared to such as friend and is usually constrained the time of arrival of less dirigibility.
In this determining step, can also determine the second travel route between this departure place and this destination, this second travel route represents the most economical path between this departure place and this destination.Alternatively or additionally can determine that the third line between this departure place and this destination sails route, this third line is sailed route and is represented the shortest path between this departure place and this destination.In the step of this destination navigation route of this acquisition, correspondingly so can realize the change of this travel route, the path most economical with this or the corresponding section in this shortest path replace the section of this travel route.At this, concept " path " can be understood in this specification, represent the route determined under using route to find normal conditions, thus it such as represents the fastest route, the shortest route or most economical route.The section that such as the second travel route can be navigated by the street of numerical map forms, these sections are that vehicle achieves separately and has the current of best conservation of fuel compared to other possible sections of the street navigation between departure place and destination, and the third line is sailed the section that route navigates by the street of numerical map and formed, these sections are that vehicle achieves the shortest current of route separately compared to other possible sections of the street navigation between departure place and destination.According to this form of implementation, also destination navigation route can be determined thus, if the duration that can change traveling is thus positioned within this time interval to make the time point arriving destination, so this destination navigation route by least one section in the fastest travel route and save most and/or at least one section in the shortest travel route formed.Can such as be preset by driver in the expansion of this form of implementation, if the use in two sections can meet the condition of reaching on the time, whether the section of this travel route should be replaced by the section of (also namely most economical) saved most or the shortest route.
According to another form of implementation, period on the section in the most economical or the shortest path of this vehicle between this departure place of expression and this destination of this destination navigation route, if receive the information of the event of the traffic jam about the section, front about this destination navigation route, so in the step obtaining this destination navigation route, realize sailing route from this second travel route or this third line and be converted to this travel route.Information such as about the event of traffic jam can relate to the accident occurred in real time on the section, front of this destination navigation route.This information can be such as received by the Traffic Announcement in vehicle.According to this form of implementation, if such as the fastest travel route is current be not used to destination navigation, so this fastest travel route can be present in backstage always.During the upper once chance provided of navigating in the street of numerical map, always can easily switch back this fastest travel route.In this way, even if when there is unforeseen event, prime opportunity can be set up for arriving punctually at the destination.
In addition, the method can have the step obtaining at least one and be applicable to travelling the place suspended.This at least one place obtained correspondingly can be used in the step of this destination navigation route of this acquisition to realize the interruption of this travel route.At this, being applicable to travelling the place suspended can be the parking lot with beautiful scenery, this parking lot driver and possible co-driver can during longer driving process movable legs and feet and having a breath of fresh air.With this form of implementation, by comfortable form, driver is stopped arrange traveling to suspend, otherwise driver may just or by very late just not have driving to suspend at all.In this way can according to the quantity of the fatigue state minimizing accident effectively of driver.Such as can realize in different places the acquisition being applicable to the place travelling time-out based on the selection preset by driver.
The method can also have the step obtaining and travel at least one duration suspended.Wherein in the step of this destination navigation route of this acquisition, this at least one duration obtained can be used further to realize the interruption of this travel route.This form of implementation provides for the shopping loosened or plan in driving process, the chance not having pressure of having a meal and refueling, and continue information how long because have to suspend about this traveling that arrives punctually at the destination.
According to another form of implementation, reading in the number of times of the time-out of realization traveling further in the data step about this time interval and/or reading in of the ratings of duration.The number of times that correspondingly can this traveling be used to suspend in this destination navigation route steps of acquisition and/or the ratings of duration are to realize the interruption of this travel route.The number of times that such as this traveling is suspended and/or the ratings of duration is determined by the driver of vehicle or such as automatically determine based on the environmental baseline during the duration travelled or traveling between departure place and destination.Such as, relative to shorter driving process, may using longer time-out as recommendation in longer driving process, and the traveling on the highway at night can need traveling of more times number to suspend compared to the traveling of the equal length on highway by day.Advantageously can in the process of moving by suspend number of times or the duration with dominate matching criteria.Therefore, it is possible to raising driving safety.
So can realize the interruption of this travel route in the step of this external acquisition destination navigation route, namely travel route is divided in time and/or spatially isometric section in margin tolerance.Advantageously, can realize travelling and suspend by the total duration of traveling that is substantially uniformly distributed between departure place and destination.This driver being vehicle provides optimum rest condition.
According to another form of implementation, determine from the step of this travel route of this departure place to this destination, so to determine this travel route, the region of the numerical map being known as high traffic density that detours at this.The corresponding section such as can sailing route with second or the third line automatically replaces and such as often occurs that block, on travel route express highway section on the specific date.Advantageously can realize the fluctuation that the most probable of calculated running time is little, thus can determine with higher reliability the time arriving destination.
In addition, propose a kind of for obtain to arrive in predetermined time interval destination, between departure place and this destination, the equipment of the destination navigation route of vehicle, wherein this equipment has following characteristics:

Fig. 1 shows according to an embodiment of the invention, according to the principle schematic at the destination navigation of this method proposed.Schematic diagram in Fig. 1 such as can represent the section from numerical map in simplified form, can such as shown in the display device of guider as section.Show departure place 100 and destination 110.Show in addition and be distributed in the first travel route 120, second travel route 130 between departure place 100 and destination 110 separately and the third line sails route 140.First travel route 120 is made up of the first section 120a, the second section 120b and the 3rd section 120c.Second travel route 130 is made up of the first section 130a, the second section 130b and the 3rd section 130c.The third line is sailed route 140 and is made up of the first section 140a, the second section 140b and the 3rd section 140c.Travel route 120,130,140 has the place 150,160 being applicable to travelling time-out.According to the schematic diagram in Fig. 1, travel route 120,130,140 represents in " path saved most ", " the shortest path " and " the fastest path " between departure place 100 and destination 110 respectively.With thick line illustrate according to obtain in this method proposed, destination navigation route 170 between departure place 100 and destination 110.
In the embodiment illustrated in figure 1, destination navigation route 170 is made up of section 140a, section 120b and section 140c.Such as can so set up this composition, namely algorithm obtains, and the fastest travel route 140 travels, will arrive destination too early.Use the section 120B of travel route 120 saved most suitably to extend to travel the duration and fuel saving simultaneously.This external place 160, plan has the traveling limiting the duration and suspends.Corresponding to these features of destination navigation route 170, the vehicle that can realize along this destination navigation route 170 arrives destination 110 within predetermined time interval.
Fig. 2 show for obtain to arrive in predetermined time interval destination, between departure place and described destination, the process flow diagram of the embodiment of the method 200 of the destination navigation route of vehicle.Read in the data representing the time interval arriving destination in step 210.Determine the travel route from departure place to destination in a step 220.Numerical map is used to be realized at this.In a step 220, so determine this travel route, make this travel route represent " the fastest " path from departure place to destination.Step 210 and 220 can be implemented in any order or concurrently.Check in the driving process on this travel route subsequently in step 230 based on step 210 and 220, time of arrival, whether point was positioned at this time interval.If determine that this time of arrival, point was positioned at outside this time interval, then in step 240 subsequently, obtain this destination navigation route by the travel route suitably changed and additionally or alternatively interrupt determining in a step 220.At this, so change and/or interrupt this travel route, making on this destination navigation route to need from departure place to the traveling of destination the running time more grown than the traveling on this travel route and/or unbroken traveling.At this, especially can check regularly in the process of moving such as whether no longer reach now temporal target zone (Zielkorridor) and therefore should mating route according to new traffic conditions.
Fig. 3 show for obtain to arrive in predetermined time interval destination, between departure place and destination, the block scheme of the embodiment of the equipment 300 of the destination navigation route of vehicle.Equipment 300 is placed and is configured in vehicle to perform the method according to Fig. 2.Equipment 300 comprise device 310 for reading in, for determine device 320, for the device 330 that checks and the device 340 for obtaining.At this, especially can check regularly in the process of moving whether no longer reach now temporal target zone and therefore should mating route according to new traffic conditions such as equally.
In the device 310 for reading in, read in the data about the time interval arriving destination via suitable Interface realization.These data can such as be provided to these interfaces with the form inputed in the guider of vehicle by the driver of vehicle or automatically be provided to these interfaces via vehicle bus.Device 320 for determining can be the guider of vehicle.
The embodiment shown in figure 3 according to equipment 300, in device 320, determine the travel route from departure place to destination by the use numerical map 350 be present in vehicle, it represents in " the fastest path " between departure place and destination.Via the interface that other are applicable to, the data of device 310 and device 320 are transferred to the device 330 for checking.Based on received data, such as check in the driving process on this travel route by means of the algorithm be applicable in device 330, whether some time of arrival that object is located in is positioned at this time interval.Check that the result of step is transferred to the device 340 for obtaining destination navigation route via the other interface be applicable to.If the result that the detection in device 330 produces is positioned at outside this time interval for this time of arrival puts, so in device 340, obtain destination navigation route, wherein so change and/or interrupt the running time that this travel route makes to extend to destination and arrive the time of destination within this time interval to make realizing vehicle.Via the other interface be applicable to, the data being used for obtained destination navigation route are transferred to device 360 and are used for showing this destination navigation route.
In sum, it is not arrive destination as quickly as possible that the algorithm had in this method proposed is intended to pursue, but arrives destination on schedule, such as, within time window.This algorithm can to realize in navigational system and in the form of software as the menu point in navigational system for driver.For this algorithm, driver can input following information in this system: the surge time gap and the expectation number of times of selectable time-out and duration before the time of arrival of the time point the latest such as arrived time of arrival of expectation, the arrival of expectation.Based on these information, present algorithm can according to different criterion calculation routes 170.Such as so can realize the selection of running section 170, make to arrive realize by surge time gap and the time window of expectation that forms time of arrival in.In particular, this algorithm follows the standard of " the fastest route " 140 at this, changes namely " variation ", as long as until reach the window of expectation.This naturally only have be only when there is the abundant time possible.Once this is spendable, then can realize the analysis of blocking or traffic density data further.At this, target is exactly expect that the running time calculated fluctuates as small as possible.Such as, can detour the express highway section being known as and blocking easily occurs.In addition, if expect, such as restaurant, refuelling station, parking lot, scenic spot etc. be applicable to place 150,160 can be acquired and for suspend and be incorporated in in route.Ideally, suspend and be distributed on running time fifty-fifty.
According to the form of implementation substituted, guider can calculate the running time of " the fastest " route 140, " the shortest " route 130 and " most economical " route 120 according to the input of time of arrival.If all can not time of arrival be realized for route options 120,130,140, so adopt the route of suboptimum and correspondingly inform driver's such as " can not observe time of arrival according to traffic conditions, you can arrive your destination as far back as 16:15 ".The division of 15 minutes can be adopted for the running time within two hours.The division of 30 minutes can be adopted for the two little running times up to five hours.For the running time more than five hours, based on hour data be significant.
If the running time of the fastest route 140 is enough, and take turns to most economical route 120, but this running time is also not exclusively enough for most economical route 120, so guider can so calculate mixing route, this mixing route comprises the fastest route 140 on the one hand, comprises most economical route 120 on the other hand.If have the running time on " most economical route " 120, so preferably " most economical route " 120.If there is the more time to remain, " the shortest route " 130 so also can be advised.If driver has arranged traveling, so " the fastest route " 140 has been kept at backstage by guider, can switch to " the fastest route " 140 at any time when going wrong.
