Vehicle location determination portion 11 is function parts of determining as the vehicle location (subject vehicle position) of subject vehicle 80 existing positions.That is, vehicle location determination portion 11 is determined the vehicle location of subject vehicle 80, in order to proceeded to the Route guiding till the destination and various information on vehicle location are provided by Route guiding calculating part 61.The information that vehicle location determination portion 11 use are obtained by gps receiver 52, aspect sensor 53, range sensor 54 etc., utilization is based on GPS(global positioningsystem: measurement GPS) or control based on the self-discipline of dead reckoning (Dead-Reckoning) and calculate, determine thus vehicle location.As in the situation that be equipped with on subject vehicle 80 camera 51, vehicle location determination portion 11 also can also have the atural object recognition function, in order to improve positional precision.Namely, the view data that vehicle location determination portion 11 also can obtain based on taking vehicle-surroundings is carried out image recognition to the atural objects such as road sign (spraying) that are located on the road surface, and by contrasting to determine the vehicle location of subject vehicle 80 with the positional information that is kept at the expression road in the road-map-data storehouse.
Road-map-data storehouse 12(road-map DB) be the database of preserving the information of road network.For example, preserve the information such as shape, road width, current classification of length, the road of classification (classifications such as highway, toll road, national highway, provincial highway), the road of link information between road (as the node of tie point and as the road chain of the road between tie point), road in road-map-data storehouse 12.Current classification also contains in highway etc. the current direction to this road appointment.In addition, the information of various freeway infrastructures (service area, parking area, expressway entrance and exit, traffic lights, convergence point etc.) also is kept in road-map-data storehouse 12.In addition, can also preserve in road-map-data storehouse 12 and be arranged on road and the information of the various atural objects (for example, road sign, pavement marker, signal lamp, mark, overpass, tunnel etc.) of road periphery, be i.e. terrestrial object information.For example, vehicle location determination portion 11 can be determined vehicle location with photographic images and these terrestrial object informations of camera 51.
Driving information acquisition unit 21 is obtained the transport condition information D I(detection information PI that becomes by reporting system 2 notice) the data (driving information) on basis.For example, driving information acquisition unit 21 is obtained the travel direction of subject vehicle 80 based on the testing result of aspect sensor 53, and the testing result of distance-based sensor 54 is obtained travel speed and the operating range of subject vehicle 80.In addition, driving information acquisition unit 21 is also obtained the vehicle location (subject vehicle position) of being determined by vehicle location determination portion 11, with the data as the basis that becomes transport condition information D I.In the present embodiment, in order to make reporting system 2 judge whether to be in retrograde state, driving information acquisition unit 21 is obtained the driving information of the information that comprises at least travel direction, and this travel direction refers to the direction that subject vehicle 80 is travelled with respect to current classification.
Road information acquisition unit 22 is to obtain the function part of road information from road-map-data storehouse 12.In the present embodiment, in order to make reporting system 2 judge whether to be in retrograde state, road information acquisition unit 22 12 is obtained road information from the road-map-data storehouse, and this road information comprises the information to the current classification of the direct of travel of road appointment that is illustrated in the vehicle location determined by vehicle location determination portion 11 at least.The information of the current classification that will be obtained by road information acquisition unit 22 offers the state judging part 23 that drives in the wrong direction.
The state judging part 23 that drives in the wrong direction is based on road information, driving information and the retrograde Rule of judgment predesignated judges whether the transport condition of subject vehicle 80 is in the function part of the state of driving in the wrong direction.Retrograde Rule of judgment refers to, for example the travel direction of subject vehicle 80 is and the direction opposite to the direct of travel of road appointment, and the situation (event) of the travel speed of subject vehicle 80 more than the datum velocity of predesignating.At this moment, the information of the travel direction that the state judging part 23 that drives in the wrong direction provides based on the information of the current classification that provides from road information acquisition unit 22 with from driving information acquisition unit 21 and the information of travel speed judge whether this travel direction is the direction of driving in the wrong direction.Obviously, also can be only with the travel direction of subject vehicle 80 be with to the situation (event) of the opposite direction of the direct of travel of road appointment as condition.In this case, the information of the travel direction that the state judging part 23 that drives in the wrong direction provides based on the information of the current classification that provides from road information acquisition unit 22 with from driving information acquisition unit 21 judges whether this travel direction is the direction of driving in the wrong direction.
Transport condition Information generation section 24 generates to comprise the transport condition information D I(detection information PI that expression is in the information of the state of driving in the wrong direction) function part.The transport condition information D I that generates is passed to transport condition information sending part 25, and this transport condition information sending part 25 is used for sending transport condition information D I to the notify objects such as administrative center 3, nearby vehicle 90 9.In addition, in order to apply flexibly this transport condition information D I in the inside of navigational system 5, the transport condition information D I that generates also is passed to transport information acquisition unit 42.Narrate in the back transport information acquisition unit 42.
Transport condition information sending part 25 is the function parts that send as the transport condition information D I of the information that represents transport condition to notify object 9.Transport condition information sending part 25 is in the situation that subject vehicle 80 is judged as the state of driving in the wrong direction that is in, when satisfying based on the driving information of subject vehicle 80 notification condition of predesignating, will be sent to notify object 9 as the transport condition information D I of the information of expression transport condition.Transport condition information sending part 25 subject vehicle 80 be in the state that drives in the wrong direction during, send constantly the information that is in the state of driving in the wrong direction.But, if merely continue to send transport condition information D I, can cause the calculated load of communication load and system to increase.Therefore, transport condition information sending part 25 sends transport condition information D I when satisfying the notification condition of predesignating.
At this, notification condition can be following situation (event), namely, for example under the state of not yet notifying the information that is in the state of driving in the wrong direction (state of " notification flag of driving in the wrong direction " described later is the state of " 0 "), be judged as the situation (initial notification condition) that is in retrograde state (state of " retrograde state-detection sign " described later has become " 1 ") by the state judging part 23 that drives in the wrong direction.In the situation that satisfy this initial notification condition, carry out for the first time sending under this retrograde state, and be " 1 " with the Status Change of " notification flag of driving in the wrong direction " described later.After this sends for the first time in execution, sending transport condition information D I when satisfying other notification condition (continuation notification condition).
for example, under the state that subject vehicle 80 is travelled with the speed more than the requirement notice speed ThV that predesignates, the first situation and/or the second situation become notification condition, described the first situation refers to, once send transport condition information D I begins through the situation of the time more than the notice time interval ThPT that predesignates in the past, described the second situation refers to, once send transport condition information D I begins subject vehicle 80 and has travelled the notice predesignated apart from the situation of the distance more than interval T hTD (being described in detail with reference to the step # 10 of Fig. 4～#12 in the back) in the past.As mentioned above, the testing result of driving information acquisition unit 21 distance-based sensors 54 is obtained the travel speed V of subject vehicle 80.At this moment, driving information acquisition unit 21 can directly be obtained travel speed from the range sensor 54 as speed pickup performance function also, also can calculate travel speed with the running time corresponding with this operating range according to the operating range of the testing result of distance-based sensor 54, thereby obtain travel speed.Namely, the state that travels with the speed more than the requirement predesignated notice speed ThV for subject vehicle 80, can judge based on the travel speed of directly obtaining from range sensor 54 grades, also can judge based on the travel speed of obtaining by calculating.
In addition, also travel speed V can have been increased the situation (event) more than the recruitment ThdV that predesignates, that is, the recruitment Δ V of travel speed V become situation (event) more than the recruitment ThdV of regulation as notification condition.Also be equal to following situation (event) this moment: the operating range in time per unit has been increased the situation (event) more than the recruitment of predesignating, that is, the recruitment of operating range has been become situation more than the recruitment of regulation as notification condition.
In addition, sailed Ordinary Rd in the situation that be in the subject vehicle 80 of the state of driving in the wrong direction into from expressway entrance and exit, or sailed in the situation of service area and parking area, or in the situation that stop in this process, retrograde state on the travel of highway is disengaged, and perhaps finishes the detection of driving in the wrong direction.The transport condition information D I that therefore, expression need to be finished to be in the notice of the state of driving in the wrong direction is sent to notify object 9.Because upgrade the transport condition information D I that will send by transport condition Information generation section 24 based on the judged result of the state judging part 23 that drives in the wrong direction etc., as long as so satisfy notification condition, transport condition information sending part 25 just sends the transport condition information D I that the expression end is in the notice of the state of driving in the wrong direction.For example, preferably, subject vehicle 80 has been passed through to comprise at least the situation (event) on the border between the travel of the freeway infrastructure of expressway entrance and exit and highway, as the notification condition of this moment.
The example on the border between the travel of freeway infrastructure and highway has been shown in Fig. 5 and Fig. 6.Represent direct of travel Y(Y1～Y3) to the road appointment at Fig. 5 and Fig. 6 hollow core arrow.Y1 represents the travel H(main line of highway, main road) direct of travel Y, Y2 such as represents from travel H to service area and parking area at the direct of travel Y of deceleratuib lane of the guiding road of high speed highway facilities F and Ordinary Rd R, and Y3 represents the direct of travel Y from freeway infrastructure F and Ordinary Rd R to the acceleration lane of the guiding road of travel H.In addition, the driving trace of solid arrow Z indicated object vehicle 80.
As Fig. 5 and shown in Figure 6, the situation that subject vehicle 80 is travelled with the state that drives in the wrong direction on travel H for example can suppose that direct of travel Y3 with respect to acceleration lane drives in the wrong direction and the situation that enters freeway infrastructure F or sail Ordinary Rd R into.As a mode, the boundary B (B1, B4) between the travel H that guiding road or the border between linking-up road of travel H and acceleration lane etc. can be defined as freeway infrastructure F and highway.Perhaps, also can notify the situation that is in the state of driving in the wrong direction in during driving in the wrong direction on guiding road or linking-up road in subject vehicle 80, also the border between guiding road or linking-up road and freeway infrastructure F or Ordinary Rd R can be defined as boundary B (B2, B5).Perhaps, also can be with such guiding road or linking-up road be defined as boundary B (B3, B6) midway.
Transport condition information sending part 25 when " notification condition " that satisfy as described above, sends transport condition information D I via communication module 58, and this communication module 58 has not shown antenna and modulation circuit etc.Communication module 58 is brought into play function as the transmitter that sends transport condition information D I, and brings into play function as receiver.That is, communication module 58 receives the transport condition information D I that sends from other vehicles and the transport information TI that sends from administrative center 3 etc., and it is passed to transport information acceptance division 41.Transport information acceptance division 41 receives via the transport condition information D I of communication module 58 from transport information TI and/or the transmission of other vehicles.
The transport condition information D I of the transport information TI that transport information acquisition unit 42 will be received by transport information acceptance division 41, the transport condition information D I of other vehicles and the vehicle (subject vehicle 80) that generated by transport condition Information generation section 24 is passed to Route guiding calculating part 61.Route guiding calculating part 61 is according to importance degree and/or the urgency of the information that receives from transport information acquisition unit 42, exports transport information TIs and/or based on the report information of transport condition information D I via user interface part 13 to monitoring arrangement 59 in the moment of predesignating.For example, in the situation that comprise information as vehicle and/or other vehicles are in the state of driving in the wrong direction in transport information TI and/or transport condition information D I, due to importance degree and urgency all high, thereby preferably in time show and report information by voice to the user by monitoring arrangement 59.At this moment, vehicle (subject vehicle 80) in the situation that be in the vehicle of the state of driving in the wrong direction, the state that should finish rapidly to drive in the wrong direction, thereby preferably report vehicle and be in retrograde situation and should make situation (event is advised) that car stops rapidly near curb etc. etc.In addition, be other vehicles in the situation that be in the vehicle of the state that drives in the wrong direction, preferably report and will notice that the place ahead travels and increase vehicular gap, thereby can remind the attention that abundant correspondence etc. is carried out in the action of avoiding other vehicles of periphery.
Among the transport condition information D I that the reporting system 2 from subject vehicle 80 sends, comprise at least the information that indicated object vehicle 80 is in the state of driving in the wrong direction.As a mode, come indicated object vehicle 80 whether to be in retrograde state with retrograde state-detection sign.For example, in the situation that the value of the state-detection sign that drives in the wrong direction is " 0 ", subject vehicle 80 is not in retrograde state, in the situation that the value of this sign is " 1 ", subject vehicle 80 is in retrograde state.In addition, preferably, except the state-detection sign that drives in the wrong direction, also comprise the information of the travel speed of the information of coordinate (subject vehicle position) of indicated object vehicle 80 and subject vehicle 80 in the status information DI that travels.For example, receive the nearby vehicle 90 of the information as being in the state of driving in the wrong direction, the moment that the vehicle that can infer vehicle (nearby vehicle 90) and drive in the wrong direction (vehicle that drives in the wrong direction is subject vehicle 80 at this) meets with etc.Then, can hide in nearest service area etc., until the vehicle that drives in the wrong direction crosses the rear of vehicle (nearby vehicle 90) or the retrograde status releasing of retrograde vehicle.The information of the coordinate of indicated object vehicle 80 is not limited to the subject vehicle position, can be also the information of the existing road chain of subject vehicle 80.
In addition, in the situation that travel has a plurality of tracks, preferably contain the information in the track that retrograde vehicle (subject vehicle 80) travels in the status information DI that travels, can select safer track so that receive the nearby vehicle 90 that is in the such information of the state of driving in the wrong direction.For example, in the situation that can not hide into nearest service area etc. or can not hide into Ordinary Rd from nearest expressway entrance and exit in the vehicle residing position of driving in the wrong direction, the nearby vehicle 90 that receives information can be selected safer track.
In addition, transport condition information D I preferably comprises the information that subject vehicle 80 has begun retrograde place.For example, administrative center 3 from having begun expressway entrance and exit to drive in the wrong direction or begun retrograde etc. information from service area or parking area, extracts in the mode of statistics the freeway infrastructure F that easy generation is driven in the wrong direction by accumulation.And, can point out abundant confirmation direct of travel to the vehicle that enters highway from this expressway entrance and exit or from vehicle of this service area grade etc.
Below, utilize the process flow diagram of Fig. 4, illustrate by reporting system 2(transport information notice system) the travel example for the treatment of step of status information of notice.Vehicle location determination portion 11 by navigational system 5 determines that vehicle location is the existing position of subject vehicle 80 (subject vehicle position) (#1: vehicle location is determined function/step).Then, obtain road information by road information acquisition unit 22 from road-map-data storehouse 12, this road information comprises at least and is illustrated in determined vehicle location to the information (#2: road information obtains function/step) of the current classification of the direct of travel of road appointment.In addition, obtained the driving information of the information that comprises at least travel direction by driving information acquisition unit 21, this travel direction refers to, the direction (#3: driving information obtains function/step) that subject vehicle 80 is travelled with respect to the current classification of obtaining.In addition, in function/step #3, driving information acquisition unit 21 can be obtained the travel direction that represents with absolute orientation, also can obtain with absolute orientation and the travel direction that represented by the angle between the direct of travel of current classification regulation.Perhaps, driving information acquisition unit 21 also can be obtained travel direction, and this travel direction is the direction of advancing according to subject vehicle 80 is that positive dirction or contrary direction represent with respect to the direct of travel of current classification defined.In addition, in the present embodiment, the travel speed V that driving information acquisition unit 21 is also obtained subject vehicle 80 reaches cumulative operating range TD as driving information (being described in detail in the back).
Then, drive in the wrong direction state judging part 23 based on the various information of obtaining in function/step #1～#3 and the retrograde Rule of judgment predesignated as described above, judge whether the transport condition of subject vehicle 80 is the state that drives in the wrong direction (#4: retrograde state arbitration functions/step).That is, judge whether to be in retrograde state based on road information, driving information and retrograde Rule of judgment.The state judging part 23 that drives in the wrong direction is judged as when being in the state of driving in the wrong direction in subject vehicle 80, is set as " 1 " (#5: the state arbitration functions/step of driving in the wrong direction) such as the value of the retrograde state-detection sign that the flag register of the microcomputer by consisting of navigational system 5 etc. is realized.In the situation that be judged as before the state that drives in the wrong direction that is in, the value of the state-detection sign that drives in the wrong direction is set as " 1 " again from " 1 ".On the other hand, in the situation that be judged as before the state that drives in the wrong direction that is not in, the value of the state-detection sign that drives in the wrong direction is changed to " 1 " from " 0 ".Similarly, the state judging part 23 that drives in the wrong direction is judged as when not being in the state of driving in the wrong direction in subject vehicle 80, and the value of the state-detection sign that drives in the wrong direction is set as " 0 " (#21: the state arbitration functions/step of driving in the wrong direction).Be in the situation that be judged as before the state that drives in the wrong direction, the value of the state-detection sign that drives in the wrong direction has been changed to " 0 " from " 1 ".On the other hand, in the situation that be judged as before the state that drives in the wrong direction that is not in, the value of the state-detection sign that drives in the wrong direction is set as " 0 " again from " 0 ".
Transport condition Information generation section 24 generates transport condition information D I, and this transport condition information D I comprises the information whether expression is in the state of driving in the wrong direction, and the information of the transport condition of indicated object vehicle 80.Preferably, with the transport condition of subject vehicle 80 whether be that the state that drives in the wrong direction is irrelevant, as long as utilize the various information of the obtaining status information that becomes to travel next life in function/step #1～#3.Comprise in the status information DI that travels when driving in the wrong direction the state-detection sign, come the information of the retrograde state of additional representation according to the value of the state-detection sign that drives in the wrong direction.Namely, in the situation that be in the state of driving in the wrong direction, only cover in transport condition information D I by the state-detection sign that merely will drive in the wrong direction, generate efficiently and comprise the transport condition information D I whether expression is in the information of the state that drives in the wrong direction, and the information that does not need again additional representation to be in the state of the driving in the wrong direction status information DI that becomes to travel next life.
Generate transport condition Information generation function/step of transport condition information D I, can carry out separately independently with process flow diagram shown in Figure 4, also can carry out in a place or many places in process flow diagram shown in Figure 4.For example, although not shown in Fig. 4, when carrying out, the various information obtained and the value of retrograde state-detection sign can be reflected in transport condition information therefore preferred this mode in function/step #1～#3 after function/step #5.In addition, although be described in detail in the back, also preferably carry out transport condition Information generation function/step after function/step # 21 or #7.
If judged by the state judging part 23 that drives in the wrong direction whether the transport condition of subject vehicle 80 is the states (#4) that drive in the wrong direction, and set the value (#5, #21) of retrograde state-detection sign according to judged result, by 25 judgements of transport condition information sending part drive in the wrong direction value (#6, the #22: Tong Zhi Zhuan Condition arbitration functions/step) of notification flag.With retrograde state-detection sign similarly, such as the function of the notification flag that realized by the flag register of the microcomputer that consists of navigational system 5 etc. driving in the wrong direction.Retrograde notification flag means that the transport condition that whether will comprise subject vehicle 80 for same retrograde state is that the drive in the wrong direction transport condition information D I of the such information of state has sent once above sign.In other words, function/step # 6 and #22 be used for judgement function/step # 4 be judged as be in the state of driving in the wrong direction after, be in the process that sends for the first time transport condition information D I or for the second time in later process of transmitting.
The initial value of the notification flag of driving in the wrong direction be " 0 ", sent comprise the transport condition information D I that is in the such transport condition of retrograde state after, the value of this retrograde notification flag is set to " 1 " (with reference to #14).Therefore, in function/step # 6, when the value that is judged as the notification flag of driving in the wrong direction is not " 1 " (being " 0 "), be in the process that sends for the first time transport condition information D I.Therefore, in order notifying rapidly, retrograde state to have occured, to be transferred to transport condition message sending function/step # 13, has sent transport condition information D I via communication module 58 to notify object 9.On the other hand, in function/step # 6, when the value that is judged as the notification flag of driving in the wrong direction is " 1 ", when satisfied notification condition as illustration, send transport condition information D I in function/step # 7～#12.Below, function/step # 7～#12 is described.When functions/step # 7～#12, suitable functions/step # 22～#24.
As mentioned above, in the situation that the vehicle that drives in the wrong direction has passed through to sail Ordinary Rd into or enter service area (SA) and parking area (PA) after expressway entrance and exit (IC), reporting system 2 finishes to be in the notice of the state of driving in the wrong direction.Therefore, judge by transport condition information sending part 25 whether subject vehicle 80 has been passed through and freeway infrastructure F(IC/SA/PA) between boundary B (with reference to Fig. 5 and Fig. 6) (#7).In the situation that subject vehicle 80 has been passed through boundary B, send by transport condition information sending part 25 the transport condition information D I that comprises following information, this information refers to, the information that provides (#8) that expression is in the information of the state of driving in the wrong direction is provided.In the transport condition information D I that sends, preferably comprise the information of the freeway infrastructure F corresponding with the boundary B of passing through.For example, preferably by transport condition Information generation section 24, generate this transport condition information D I after carrying out function/step #7, perhaps this transport condition information D I is that the transport condition information D I after a part (has been appended the information of ending message or freeway infrastructure F etc.) in change.In addition, the value of the state-detection sign that drives in the wrong direction can be remained as it is expression at this time point and detect retrograde " 1 ".
When transport condition information sending part 25 has sent the transport condition information D I of the information that comprises the retrograde detection end of expression in function/step #8, the value of the notification flag of driving in the wrong direction in function/step #24 is set as " 0 ", and repeats a series of processing that begin from function/step #1.Subject vehicle 80 passed through and freeway infrastructure F etc. between boundary B, therefore become and satisfy the Rule of judgment that drives in the wrong direction.Therefore, be judged as the retrograde state that is not in the function in a series of processing that repeat/step #4, the value of the state-detection sign that drives in the wrong direction in function/step #21 thus is changed and is " 0 ".Then, the value of the retrograde notification flag of judgement in function/step #22.The value of the notification flag of driving in the wrong direction has been changed in the function in front once a series of processing/step #24 and has been " 0 ".Therefore, transport condition information sending part 25 does not send transport condition information D I, and the value of the notification flag of driving in the wrong direction is set as " 0 " again, and repeats a series of processing from function/step #1.
In function/step # 7, if be judged as subject vehicle 80 not by and freeway infrastructure F(IC/SA/PA) between boundary B, judge whether to satisfy each notification condition of function/step # 9～#12.In function/step # 9, more than whether the recruitment Δ V that judges travel speed V has increased the recruitment ThdV that predesignates.Be not less than at the recruitment Δ V that is judged as travel speed V in the situation (in the situation more than the recruitment ThdV of regulation) of the recruitment ThdV of regulation, be transferred to concurrent the seeing off of function/step # 13 and sail status information DI.The transport condition information D I that this transport condition information D I is for example preferably generated after function/step # 5 by transport condition Information generation section 24.In addition, also can replace the recruitment Δ V of travel speed V, situation more than the recruitment of predesignating that the operating range in time per unit has been increased is as notification condition.
In the situation that the recruitment Δ V that is judged as travel speed V in function/step # 9 less than the recruitment ThdV of regulation, is transferred to function/step # 10 and judges whether to satisfy other notification condition.In function/step # 10, judge that the travel speed V of subject vehicle 80 is whether more than the requirement notice speed ThV that predesignates.In the situation that travel speed V because subject vehicle 80 is also little with the speed that relative car to sailing approaches, thereby does not send transport condition information D I, and repeats a series of processing that begin from function/step #1 less than requiring to notify speed ThV.
In addition, as mentioned above, in retrograde state arbitration functions/step # 4, with the travel speed V of subject vehicle 80 whether the situation more than the datum velocity of predesignating as the Rule of judgment that drives in the wrong direction.As a mode, also can notify the datum velocity of speed ThV and retrograde Rule of judgment to be set as identical value with requiring.At this moment, due to the travel speed V that has been judged as subject vehicle 80 by the state judging part 23 that drives in the wrong direction more than datum velocity, namely more than requiring to notify speed ThV, thereby can omit function/step #10.Obviously, in the situation that function/step # 10 is set, preferably will require to notify speed ThV to be set as the speed higher than the datum velocity of retrograde Rule of judgment.
In function/step # 10, in the situation that be judged as travel speed V more than requiring to notify speed ThV, judgement once sends elapsed time PT that transport condition information D I begins whether more than the notice time interval ThPT that predesignates (#11) in the past.The mensuration of elapsed time PT is such as being realized by the timer of the microcomputer that consists of navigational system 5 or counter etc.Be not less than at elapsed time PT in the situation (elapsed time PT is in the situation more than notice time interval ThPT) of notice time interval ThPT, be transferred to concurrent the seeing off of function/step # 13 and sail status information DI.The transport condition information D I that this transport condition information D I is for example preferably generated after function/step # 5 by transport condition Information generation section 24.
On the other hand, in function/step # 11, in the situation that be judged as elapsed time PT (elapsed time PT is less than notice time interval ThPT) not more than notice time interval ThPT, judge whether to satisfy other notification condition in function/step #12.That is, judgement once sends cumulative operating range TD that transport condition information begins whether more than the notice of predesignating is apart from interval T hTD (#12) in the past.Come the testing result of accumulation distance sensor 54 such as counter, general-purpose register and the totalizer etc. that can utilize the microcomputer that consists of navigational system 5, realize thus the calculating of cumulative operating range TD.In the situation that cumulative operating range TD is transferred to concurrent the seeing off of function/step # 13 and sails status information DI more than notice is apart from interval T hTD.The transport condition information D I that this transport condition information D I is for example preferably generated after function/step # 5 by transport condition Information generation section 24.
Function/step # 10 and #11 illustration with following situation (condition A) as notification condition, send the mode of transport condition information D I, this situation (condition A) refers to, under the state that subject vehicle 80 is travelled with the speed more than the requirement predesignated notice speed ThV, once send the situation that elapsed time PT that transport condition information D I begins reaches the notice time interval ThPT that predesignates in the past.In addition, function/step # 10 and #12 illustration with following situation (condition B) as notification condition, send the mode of transport condition information D I, this situation (condition B) refers to, under the state that subject vehicle 80 is travelled with the speed more than the requirement predesignated notice speed ThV, once send cumulative operating range TD that transport condition information D I begins subject vehicle 80 in the past and reached the notice predesignated apart from the situation of interval T hTD.
Like this, in function/step # 10～#12, illustration under the state that subject vehicle 80 is travelled with the speed more than the requirement predesignated notice speed ThV, with the situation of satisfy condition A or the condition B mode as notification condition.But, be not limited to this mode, also can be under the state that subject vehicle 80 is travelled with the speed more than the requirement predesignated notice speed ThV, with the situation of satisfy condition A and condition B as notification condition.
In addition, in mode shown in Figure 4, show following example, namely, notify speed ThV in the situation that be judged as the travel speed V of subject vehicle 80 in function/step # 10 less than requiring, repeat a series of processing that begin from function/step #1, and do not send transport condition information D I.But, be not zero in the situation that require to notify speed ThV, even with low speed driving, also there is the possibility of travelling with the state that drives in the wrong direction in subject vehicle 80.Therefore, in the situation that the travel speed V that is judged as subject vehicle 80 in function/step # 10 is less than requiring to notify speed ThV, also preferably will once send situation that elapsed time PT that transport condition information D I begins reaches the maximum notice time interval of predesignating as notification condition in the past, send transport condition information D I.At this, preferably maximum is notified the time interval to be set as the large value than notice time interval ThPT.
In addition, in the situation that the travel speed V that is judged as subject vehicle 80 in function/step # 10 is less than requiring to notify speed ThV, for example, also can supspend the instrumentation to elapsed time PT that (maintenance) undertaken by the timer of the microcomputer that consists of navigational system 5 or counter etc., or the elapsed time PT that resets.Similarly, such as the accumulation calculating to cumulative operating range TD that also can supspend (maintenance) counter by the microcomputer that consists of navigational system 5, general-purpose register, totalizer etc. and carry out, or replacement operating range TD.Yet the instrumentation of the elapsed time PT that also can supspend or reset continues cumulative operating range TD is carried out accumulation calculating on the other hand, and the accumulation calculating of cumulative operating range TD of can also supspending or reset continues instrumentation elapsed time PT on the other hand.
In addition, also not in the process flow diagram with Fig. 4 illustrative " notification condition " be applied to the whole of this process flow diagram.For example, also can be notification condition with the arbitrary condition in the notification condition of the notification condition of function/step # 9 and function/step # 10～#12 is applicable.In addition, also the notification condition of function/step # 7～#8 can be applicable to one or both in the notification condition of the notification condition of function/step # 9 and function/step # 10～#12, notification condition that also can inapplicable function/step # 9 and the notification condition of function/step # 10～#12.
As explained above, according to the present invention, can provide and effectively and to notify efficiently the transport information of the transport condition of the subject vehicle that is in the state of driving in the wrong direction to notify system from subject vehicle to notify object.
