Below will explain the operation of the navigator 20 in the present embodiment, it is used for showing along the Weather information of the navigation way of setting on display unit 26.
[to the description of Weather information display process]
Fig. 2 shows the process flow diagram of the performed Weather information display process process of the control module 29 of navigator 20.
At first, in step S10 (following represent step), determine that route is set whether to finish with symbol S.When in the independent route setting of carrying out is handled, having set the navigation way of destination, a predetermined sign is set.In S10, determine whether this sign is provided with.
(S10: not), step S10 oneself does not repeat to wait for, till route is set when setting this route.When having set route (S10: be), handle advancing to S20.
Then, in S20, determine whether the user is used to begin the instruction of Weather information display process via operating switch group 22 or wireless remote controller 23a input.If there is this instruction (S20: be), handle advancing to S30.(S20: not), handle the oneself and repeat when in S20, also not importing this instruction.
In S30, obtain each localized weather information along the route of having set.Various forms can be adopted although be used to obtain the technology of each localized weather information, following 3 examples will be explained in this case.
(1) for example, upgrade no matter when and when receiving Weather information, can upgrade the Weather information in the external memory storage 28 via broadcasting (for example FM multiplex broadcasting or the like).Then, in the processing of S30, can obtain along the Weather information in the zone of route according to the Weather information that is stored in the external memory storage 28.
(2) in addition, for example, communicate with information center 5 via communication unit 24,, and will be stored in the external memory storage 28 from the Weather information that information center 5 sends in response to this request so that request is sent in the Weather information of accumulation in the information center 5.Then, in the processing of S30, can obtain along the Weather information in the zone of route according to the Weather information that is stored in the external memory storage 28.
(3) in the example of above (1) and (2), extract the Weather information in the zone of navigation way process by navigator 20.Yet, can in information center 5, carry out extraction to Weather information.In this case, by communicating by letter of communication unit 24 and information center 5, will be about the information of the navigation way that sets with sending for the request that sends along the Weather information of navigation way.Then, navigator 20 receives the information that is sent.
When having obtained in S30 after each localized weather information of navigation way, having handled advances to S40.Then, in S40, determine whether to exist the input of driving purpose/criterion pattern.For example, for the driving purpose, driving itself can be the driving purpose, and perhaps watching scenery can be the driving purpose.In addition, for the criterion pattern, can expect corresponding to new hand driver the criterion pattern, corresponding to general driver's criterion pattern, or the like.These criterion the mode options for example may be displayed on the display unit 26, and can accept to be used to select user's input of one of them the mode option via operating switch group 22 or remote controllers 23a.
When having the input (S40: be) of driving purpose/criterion pattern,, calculate the importance degree (S50) of each regional weather forecast according to criterion based on the driving purpose/criterion pattern of this input.For the calculating of importance degree, the importance degree of the importance degree of Weather information itself or the Weather information relevant with navigation way can obtain from a relation table, perhaps uses predetermined equation to calculate.For example, this table and the equation that is used for calculating can be stored in external memory storage 28.In the present embodiment, show to calculate importance degree, will describe the details of this calculating after a while based on this.
According to the importance degree result of calculation in S50, extract Weather information (S60).For the extraction of Weather information, can extract Weather information with predetermine level or more high-grade importance degree, perhaps can extract according to the n that is calculated an of paramount importance Weather information.To describe importance degree after a while in detail calculates.
When in S60, having extracted Weather information, on display unit 26, show the Weather information (S70) that is extracted.As shown in Figure 3A, can use along the mark of navigation way placement and represent the Weather information that each is regional respectively, so that the user represents the weather in which zone according to which mark and discerns easily.Like this, promptly can be illustrated in the three unities (i.e. zone) on the map and the relation between its weather intuitively.
In addition, shown in Fig. 3 B, can show a tabulation independently on another screen except map display screen and/or route display screen, it shows the weather mark that is associated with the zone.For example, can on display unit 26, carry out double screen and show, on a screen, show route, with the Weather information of the tabular form of another screen display shown in Fig. 3 B.
In addition, be described in details and the extraction of the Weather information in the S60 details that the importance degree among the S50 calculates with reference to figure 4 to 6.
Also explain the effect of each processing simultaneously.
[the importance degree calculating of Weather information and the extraction of Weather information]
Can calculate the importance degree of Weather information based on Weather information self, perhaps can be based on calculating this importance degree with the relation of navigation way.
(1) importance degree based on Weather information self distributes
Fig. 4 A shows the example that distributes the table of importance degree to Weather information self.Corresponding to Weather information, importance degree is set within 0 to 1 the scope.For example, under the situation of fine gas, the importance degree of Weather information is 0.1, the importance degree of cloudy weather also is set at 0.1, and rainy importance degree is set at 0.6, and the importance degree of heavy rain is set at 0.8, the importance degree of typhoon is set at 1, and snowy importance degree is set at 0.9, or the like.
Its thought is, influences possibly along the Weather information of the driving of navigation way to have higher importance degree.For example, because fine/cloudy weather is relatively low to the possibility that driving counteracts, therefore set the importance degree of these weather relatively low, owing to heavy rain/typhoon/snowy weather counteracts possibly, so these weather have higher relatively importance degree.
In the S60 of Fig. 2, extract Weather information based on importance degree result of calculation.For example, be fine/cloudy weather of 0.1 when extracting 0.5 or during higher importance degree, not extracting importance degree, be that 0.6 rainy day and importance degree are 0.9 snow sky and extract importance degree.
When obtaining the importance degree of Weather information, also obtain the accuracy (if it can obtain) of Weather information.For the accuracy of Weather information, adopt prediction probability itself.
An example of the table that between the table shown in Fig. 4 B and the 4C can be as definition importance degree of Weather information and accuracy, concerns.
In the table shown in Fig. 4 B, accuracy between 0 to 5% has importance degree 0 (zero), and the accuracy between 5 to 10% has importance degree 0.1, along with the every increase by 10% of accuracy, importance degree increases step-length 0.1, and importance degree is 1 when the scope that reaches 90% to 100% when accuracy.Relation between accuracy and the importance degree draws out shown in Fig. 5 A.
On the other hand, shown in Fig. 4 C, 0% accuracy has importance degree 0 (zero), and the accuracy that the accuracy that 25% accuracy has an importance degree 0.1,75% has importance degree 0.9,100% has importance degree 1.Promptly, scope at the accuracy between 25% to 75% and scope each importance degree in 75% to 100% accuracy, is to calculate respectively by the linear interpolation of using the boundary value of each in these scopes in the accuracy between 0 to 25%, scope.In this case, the relation between accuracy and the importance degree draws out shown in Fig. 5 B.
For example, the importance value at the Weather information shown in Fig. 4 A can be multiply by the importance value in Fig. 4 B or Fig. 4 C, to calculate final importance degree.
(2) importance degree that is associated with navigation way distributes
(2-1) importance degree with rising of the n cut-point of navigation way
When the roughly situation of having grasped along the Changes in weather of whole navigation way, facilitate the user and determine to adopt certain particular navigation route.For example, when each city, cities and towns and rural Weather information can obtain, just there is each the Weather information in each zone of locating every several kilometers (depending on shape and size that each is regional).When too many, preferably simplifying so that easier making decision to Weather information along the Weather information of the All Ranges of whole navigation way.
Therefore, the importance degree of Weather information in zone that comprises the n cut-point (" n " is the integer more than or equal to 2) of navigation way may raise with respect to other regional Weather informations.In addition, can determine the lower limit of the section length after having cut apart navigation way, to avoid the too short segmentation of length.For example, when lower limit being set at 10km etc., can avoid Weather information to extract every 5 kilometers.In addition, can determine to cut apart the value of quantity " n ", so as to avoid with navigation way be divided into have the section length littler than this lower limit than subsection.
In addition, can change the lower limit of section length according to road type.For example, can use the value of 20km for highway.
Similarly, can be divided into a plurality of parts estimated running time, be included in each n and cut apart the weather in the zone in the place that driving is arrived after running time and can have higher importance degree.
(2-2) zone with longer navigation way/comprise longer running time has the importance degree of rising
Fig. 6 A shows the example of definition by the table that concerns between length and the weather importance degree.In this example, the length of navigation way in a zone is associated with importance value with the ratio of the path length (that is total length) of total navigation.
More specifically, by length divided by the ratio of total length 0 between 1/100 the time, has importance degree 0, by length divided by the ratio of total length 1/100 between 1/75 the time, has importance degree 0.2, by length divided by the ratio of total length 1/75 between 1/50 the time, have importance degree 0.4, by length divided by the ratio of total length 1/50 between 1/25 the time, have importance degree 0.6, by length divided by the ratio of total length 1/25 between 1/10 the time, have importance degree 0.8, by length divided by the ratio of total length 1/10 between 1/5 the time, have importance degree 0.9, by length divided by the ratio of total length 1/5 between 1 the time, have importance degree 1.
In other words, in the Weather information that each zone obtained, and have the regional corresponding Weather information of longer navigation way and be configured to have higher importance degree by length.
Fig. 6 B shows the example of the table that concerns between definition running time and the weather importance degree.In this example, the ratio of the running time (that is T.T.) of the running time of navigation way in a zone and total navigation way is associated with importance value.Route is set and/or the technology of the guiding of navigator about being used for, and has proposed several different methods.Therefore, the running time in certain specific region and total driving time calculate easily.
More specifically, running time divided by the ratio of T.T. 0 between 1/100 the time, has importance degree 0, running time divided by the ratio of T.T. 1/100 between 1/75 the time, has importance degree 0.2, running time divided by the ratio of T.T. 1/75 between 1/50 the time, have importance degree 0.4, running time 1/50 between 1/25 the time, has importance degree 0.6 divided by the ratio of T.T., running time divided by the ratio of T.T. 1/25 between 1/10 the time, have importance degree 0.8, running time 1/10 between 1/5 the time, has importance degree 0.9 divided by the ratio of T.T., running time 1/5 between 1 the time, has importance degree 1 divided by the ratio of T.T..
In other words, in the Weather information that each zone obtained, be configured to have higher importance degree with the regional corresponding Weather information of needs longer running time.
By this way, the longer running time at the specific region middle rolling car that is subject to weather effect can preferred reaction be the high value of the importance degree of this regional Weather information.
(2-3) zone with higher maximum speed limit has higher importance degree
Fig. 6 C shows the example of the table that concerns between definition speed limit and the weather importance degree.In this example, the speed limit in the zone is associated with importance value.Promptly, speed limit has importance degree 0 (zero) when being 0 to 20km/h, speed limit has importance degree 0.4 when being 20 to 40km/h, speed limit has importance degree 0.6 when being 40 to 60km/h, speed limit has importance degree 0.8 when being 60 to 80km/h, speed limit has importance degree 1 when being 80 to 100km/h, speed limit also has importance degree 1 during greater than 100km/h.
The Weather information in zone with fair speed restriction of traffic rules is configured to have higher importance value.This be because higher road speed be estimated as rain for example, snow, strong wind, or the like have bigger influence for driving states aspect the middle rolling car.
(2-4) according to the adjustment of condition of road surface
Under many circumstances, according to condition of road surface, Weather information is nonsensical basically.For example, in the tunnel or the driving on the underground road can not be subjected to the influence of this regional weather.Therefore, the importance degree of Weather information in this case is lowered.
(3) importance degree based on other criterions distributes
(3-1) according to changing importance degree the scheduled time
Fig. 6 D shows the example of table of importance degree being distributed to one day the moment.Promptly, has importance degree 0.2 scheduled time between the morning 0:00 and 5:00 the time, the scheduled time the morning 5:00 have importance degree 0.5 to time between the morning 6:00, the scheduled time the morning 6:00 have importance degree 0.8 to time between the morning 7:00, the scheduled time the morning 7:00 have importance degree 1 to time between the morning 8:30, the scheduled time the morning 8:30 have importance degree 0.7 to time between the morning 9:00, the scheduled time the morning 9:00 have importance degree 0.2 to time between the morning 10:00, or the like.
Above-mentioned importance degree distribution is based on following hypothesis: the inclement weather during the travelling frequently the time in a day (commuting time) (morning or dusk) can cause the more heavy volume of traffic, thereby increases for driver's importance degree.Because with the relevant technical field of navigation in advised being used to calculating the technology of the traffic time of expection in every way, so anticipate the moment of certain appointed place on the pass course easily.
In this case, must be from the Weather information of information center's 5 acquisitions in certain particular moment in future.Realized the forecast Weather information of certain particular moment in the future routinely.Therefore, for example, in information center 5, can store every 3 hours or every 1 hour Weather information, and the Weather information of being stored can be sent to navigator 20, so that according to determining importance degree the scheduled time.
(3-2) change importance degree according to the driving purpose
Can change the importance degree of Weather information according to the driving purpose.For example, with driving this as the importance degree of the driving of purpose be that the importance degree of the driving of purpose can have different importance degrees for identical Weather information to watch landscape.
For example, be when watching landscape by day in the driving purpose, owing to lack observability at night, the importance degree of Weather information has lower value for driving at night, perhaps, when the driving purpose be when watching urban landscape, the Weather information importance degree of driving at night and day driving should be put upside down.
(3-3) distribute importance degree by use multiple criterion with overlap mode
When using above-mentioned multiple criterion, can use the criterion pattern that is used for new hand driver or is used for normal driver according to the explanation in the description of S40 with overlap mode.The criterion pattern of particular type can be associated with multiple criterion in advance, and can use by the specified multiple criterion of the criterion pattern of being imported with overlap mode, calculates the importance degree of Weather information.
For example, when use is used for new hand driver's criterion pattern, can use important kilsyth basalt based on the Weather information in Fig. 4 A, based on the important kilsyth basalt of the Weather information accuracy in Fig. 4 B or 4C and based on the important kilsyth basalt that passes through length in Fig. 6 A, calculate the Weather information importance degree in each driving zone.
Can calculate total importance degree of the Weather information in each zone in order to following equation.
(total importance degree)=by length * weather * accuracy
After having calculated importance degree, for example can be extracted in the Weather information of a top n position.
