External connecting 11 is to make external system cooperate to improve the part of the surcharge of onboard navigation system with onboard navigation system.For example, utilize the outside function connecting, the music of regeneration smart mobile phone, makes sound stream enter audio output unit 10.In addition, in communication module 2, even without the communication unit of 3G communication, radio communication etc., that also can be undertaken saying with central server by the function of external connecting 11 communicates by letter.In Fig. 2, by with the cooperating of smart mobile phone, and realize communicating by letter of onboard navigation system 203 and central server 201 via smart mobile phone 202.
Have again, in the present embodiment, before making onboard navigation system action, first, need to set necessary information of vehicles.In Fig. 3, as the formation example of information of vehicles, enumerate, in the storage medium 4 of onboard navigation system, preserve associated data, when the route guidance of following step, with reference to the data of storage medium 4.Specifically, information of vehicles 301 comprises license plate number 302, application target 303, vehicle 304, air capacity 305, Customer information 306 and other 307, and application target 303 comprises private car 308, taxi 309, fire truck 310, ambulance 311, police car 312 and other 313.
Then, when route guidance, from central server, obtain the restricted driving information of this region.This communication is realized by the communication module 2 that is built in onboard navigation system, still, also can obtain by external connecting 11 data of central server.The restricted driving data of often using also can be stored in the storage medium 4 of onboard navigation system, still, in the situation that restricted driving data are data of periodic variation restricted driving content, need to synchronize with central server termly.Also have, the restricted driving information obtaining from central server can show at the display part 8 of onboard navigation system, also can manual modification.In the situation that there is no communication unit, restricted driving information can be directly inputted to onboard navigation system.
Below, take Beijing and Shanghai as example, the process flow diagram of the route guidance of present embodiment is described.In Beijing, by the process flow diagram of Fig. 4, processed, when route guidance, first, in step S400 date of acquisition and time, in step, S401 obtains information of vehicles, at step S402, obtains restricted driving information.So-called information of vehicles, the attached information that comprises license plate number, application target (private car, taxi, fire truck, ambulance, police car etc.) etc., also comprise car type (for example, the RAV4 of Toyota, Corolla, Camry etc.), air capacity, whether carry passenger etc. from the information that can obtain by communication of vehicle computer.The classification of information of vehicles has various methods, still, in order not affect enforcement of the present invention, uses the sorting technique of Fig. 3.In addition, information of vehicles, the project that can obtain from vehicle computer is just used same as before, and the project that cannot obtain from vehicle computer is inputted by the associated input media of onboard navigation system.
In addition, restricted driving information comprises fixedly restricted driving information and variable restricted driving information, fixedly restricted driving information is on traffic signboard, to show and it doesn't matter and the information that do not change with the factors of license plate number, date, time etc., variable restricted driving information be to the date, the time period is relevant and the information that changes.For example, in Shanghai, license plate number is that the vehicle beyond the licence plate of Shanghai does not allow to utilize overpass in peak period on and off duty (7: 30～9: 30 morning of MONDAY to FRIDAY and 16: 30～18: 30 afternoon).When the vehicle to beyond the licence plate of Shanghai navigates, need to determine now.If not peak period on and off duty, can navigate at overpass, still, need to navigate in the mode not breaking the rules, so that leave overpass before the restricted driving time starts.That is,, for the vehicle beyond the licence plate of Shanghai, restricted driving information is notified to driver in real time as attention information.Calculating becomes the restricted driving time after how long, impels driver to leave overpass in the overhead outlet of necessity.According to same consideration method, under steam, if the restricted driving time finishes, use overpass to navigate.Variable restricted driving information can be stored in the data preservation treating apparatus that is arranged at vehicle, and still, the restricted driving information in each city is different, and the also often change of restricted driving content, therefore, is provided for preserving the central server of variable restricted driving information.When carrying out route guidance, from central server, download restricted driving information, compare with information of vehicles, thereby carry out route guidance.
In addition, variable restricted driving information is also the information of its restricted driving content changing of situation by bus according to the application target of vehicle and passenger.The onboard navigation system of present embodiment is confirmed the application target of vehicle and passenger's situation by bus.In Beijing, for not restriction of special car, therefore, for the special car of taxi, fire truck, ambulance, police car etc., when route guidance, ignore restricted driving information, with the travel route the most easily passing through, navigate.In Shanghai, for the taxi that does not carry passenger, in peak period on and off duty not utilize the mode of overpass to navigate.Passenger's information exchange is crossed with the data communication of vehicle computer and is obtained.
Then, confirm application target and the license plate number (step S403 and step S404) of vehicle.Whether the vehicle that will navigate in step S405 judgement thereafter, is the restricted driving vehicle on the same day.Non-restricted driving vehicle execution path searching step S406 with restrict driving digital inconsistent private car, taxi, special car etc.In addition, the in the situation that of being judged as restricted driving vehicle in step S405, carry out detour route searching step S407 and the result notifying process S408 that detours.According to the place of destination, the situation that existence cannot be detoured, if cannot detour, notifies this situation to driver.In the situation that can detouring, to driver, show the reason of the route of selecting to detour.It doesn't matter with the driving that whether is limited, and last, execution path navigation step S409 and the change timer of restricting driving are set step S410.If produce restricted driving change timer, the processing of execution graph 6 set in step S410.
Fig. 7 has described simple Pekinese map drawing, exist three rings, Fourth Ring, five rings, S12 at a high speed, 3 places such as 5 turnpike roads at a high speed etc. of G4 and the Capital Airport, Beijing West Railway Station, Changxingdian.The vehicle navigating is that license plate number is 2 private cars of capital MXXXX1 and capital MXXXX2, on January 7th, 2013, from the Capital Airport to Beijing West Railway Station and Changxingdian, travels.After having confirmed application target and restricted driving information, known capital MXXXX1 is the restricted driving vehicle on January 7, and capital MXXXX2 is not restricted driving vehicle.Therefore, for the vehicle of capital MXXXX2, execution path searching step S406, thus travel route is navigated.For example, in S12 high speed and three, go in ring and sail, then, at three rings and G4, to Changxingdian, travel at a high speed.But, because the vehicle of capital MXXXX1 is restricted driving vehicle, therefore, be not execution path searching step S406, but carry out detour route searching step S407 and the result notifying process S408 that detours.Beijing West Railway Station be positioned at three rings with place, therefore, cannot detour, to driver notice, cannot detour, still, Changxingdian is by three near rings of distance, but distance five rings far away navigate and can arrive, and certainly will notify the reason that detour to driver.That is, from the Capital Airport to Changxingdian, not with S12 high speed, three rings, G14 order setting navigation route at a high speed, but with S12 high speed, five rings, G14 order setting navigation route at a high speed.
In Shanghai, the rule of restricting driving is different from Beijing, represents the process flow diagram of processing in Fig. 5.First, in step S500 date of acquisition and time, in step, S501 obtains information of vehicles, at step S502, obtains restricted driving information.Then, in step S503, check whether be the period of restricting driving.That is,, except off-day, check to be whether section in rush hour on and off duty (morning 7:30～9:30, and afternoon 16:30～18:30).Be not rush hour on and off duty section in the situation that, execution can utilize the route searching step S508 of overpass.In rush hour on and off duty section in the situation that, vehicle beyond the Shanghai licence plate of being differentiated by the confirmation of the license plate number of step S504 becomes restricted driving object, therefore, carries out utilizing the route searching step S509 of overpass, but the vehicle of Shanghai licence plate has further inspection item.In step S505, check whether be taxi, and check whether there is passenger in step S507, in the situation that not carrying passenger, carry out utilizing the route searching step S509 of overpass, in the situation that carrying passenger, carry out utilizing the route searching step S508 of overpass.In step S511, if produce restricted driving change timer, the processing of execution graph 6 setting.
Fig. 8 has described the map drawing in simple Shanghai, the place of near the Tongji University in existing ring and Shanghai Gymnasium etc.2 private cars of the license plate number of capital MXXXXX and Shanghai NXXXXX travel to Shanghai Gymnasium from Tongji University.The private car of the license plate number of Shanghai NXXXXX and time on date, it doesn't matter, do not become restricted driving object, therefore, can be to navigate in the current mode of interior ring, still, the private car of the license plate number of capital MXXXXX is not the license plate number of Shanghai distribution, restricting driving, the time period cannot be utilized overpass, therefore, restricting driving the time period, in the mode of the non-restricted driving road beyond overpass, navigating.When the vehicle of Shanghai NXXXXX is not private car but taxi, need in step S506, obtains Customer information and judged whether passenger in step S507.In the situation that having passenger, it doesn't matter with the restricted driving time period, can use overpass.
In the zero hour of route guidance, in the situation that vehicle has entered restricted driving region or restricted driving road, first, to the minimal path that driver points out from this restricted driving region or restricted driving road is gone out.Detailed processing is tackled in the route retrieval that cannot utilize overpass of the step S509 of detour route retrieval and Fig. 5 of the step S407 of Fig. 4.
For having the restricted driving information of relation with the time period, to driver, point out restricted driving information in real time, to driver, inform the road that does not break the rules and easily pass through.To driver, notify restricted driving information in real time, have the tupe of two kinds.Existence recommendation restricted driving road and entered the situation of restricted driving road and the time period of restricting driving under steam finishes and can utilize the situation of restricted driving road before restricted driving starts.If produce the timer that the restricted driving change timer of the step S410 of Fig. 4 is set, the restricted driving change timer of the step S511 of Fig. 5 sets in setting, the processing of execution graph 6.The setting rule of timer has multiple, still, in the present embodiment, take and carve at a time that to set timer before a few minutes of (restricted driving time start, restricted driving time finish) be example.In fact, exist and take certain hour and produce the method for timer etc. as the cycle, to driver, notify in real time the opportunity of restricted driving information, the method that driver can select custom to use.Date of acquisition and time in step S600, in step S601, obtain information of vehicles, in step S602, obtain restricted driving information, obtain restricted driving content in step S603 after, in step S604, judge whether to need Reroute.The in the situation that of needs Reroute, the execution step route guidance of again retrieving route, step S607 of S606 is, the information to driver of step S608 notice.In the situation that not needing Reroute, in step S605, carry out the route guidance of present situation.Finally, in step S609, reset the change timer of restricting driving.Also have, in order easily to understand flow process from restricted driving information to driver that notify, in Fig. 6, describe, still, in the realization of system, also can together with the processing of Fig. 6 and Fig. 4, Fig. 5, carry out.
In step S608, to driver's information, notify picture as shown in Figure 10, Figure 11.Before the restricted driving time starts, in the picture of Figure 10, to driver's notice, still, before the restricted driving time finishes, in the picture of Figure 11, to driver, notify.The content of notice shows in step 1003, step 1103.Step 1005, step 1105 represent the take-off point after navigation way that the change by restricted driving content obtains before changing, in flicker in driver's notice.For the route after distinguishing before changing, the route after renewal is described with solid line, and the route before renewal dots.In addition, in the situation that can utilizing restricted driving road, by "Yes" button 1110, the "No" button 1111 of Figure 11, to driver certifying, whether utilize restricted driving road.
In addition, take Fig. 8 as example explanation treatment scheme.At MONDAY to FRIDAY 16 points of some day, the situation that the private car of MXXXXX in Beijing travels to Shanghai Gymnasium from Tongji University, owing to not being the time period of restricting driving, first, in using, ring navigates, and makes route change 16: 15 before 15 minutes that timer is 16: 30 start time of restricting driving.Within these 15 minutes, as the well-to-do time, use, can be set by onboard navigation system.At 16: 15, generation, as the timer of the triggering of the processing of Fig. 6, started the processing of Fig. 6.Confirm behind the residing position of vehicle, suppose bus station, Shanghai on interior ring near.Based on each information, in step S604, judge whether to need Reroute.After 15 minutes, become the time period of restricting driving, therefore, must in step S606, carry out route and again retrieve to carry out route guidance at 15 minutes in the interior mode of leaving overpass, thereby carry out the route guidance of step S607.Consider present traffic, for example within 25 minutes, can arrive the mode of the outlet of overpass at 16 o'clock, navigate, then the ordinary road beyond overpass is proceeded navigation.In this case, as shown in figure 10, to driver, notify restricted driving information.Finally, in step S609, reset the change timer of restricting driving.For example, the restricted driving time being set as after 2 hours finishes front 15 minutes.In the navigation of such short time, it doesn't matter with this setting, and still, in navigating for a long time, restricted driving content changes again, can produce the effect of this setting.Identical with above-mentioned processing, in the situation that the time period of restricting driving under steam finishes, also need to carry out route and again retrieve.Now, to driver's notice as shown in figure 11.
