JP 7-29099 A

  In a conventional car navigation device (hereinafter abbreviated as “car navigation”), a route to a facility at a designated destination is searched, so that it is possible to arrive near the facility by driving according to the route guidance. However, in many cases, after the route guidance of the car navigation system is finished, the driver searches for a parking position that suits his / her purpose, and thus a lot of time may be spent searching for the parking position. Moreover, even if the destination of the car navigation system is set to the parking lot of the facility or the surrounding parking lot, it is often not known if the parking lot set as the destination is vacant when it actually arrives.

  Especially in the delivery industry, it is necessary to deliver goods to the delivery destination on time or to park the vehicle at the parking position specified by the delivery destination. A guidance system is required. For example, when there are a plurality of parking lots at a destination facility, it is better for the delivery company to park near a delivery port or a material entrance, instead of the general parking lot of the facility. When the destination is a large-scale commercial facility and there are a plurality of parking lots, it is more desirable to park at a parking lot close to a store for delivery purposes. Furthermore, when the vehicle used for delivery is a large vehicle, it is necessary to stop at a specific position in the parking lot.

  It is an object of the present invention to provide a method and system for guiding a vehicle to a better parking position suitable for driving purposes.

  In order to solve the above problems, the parking position guidance system of the present invention includes, together with information on the parking position, means for acquiring from each vehicle the parking information that the driver inputs to the car navigation system during parking, and the acquired parking information from the vehicle. The parking information DB includes a parking information DB that accumulates, and the recommended parking information that determines the priority order of the recommended parking lot for the delivery company created by estimating the parking lot used from the parking information of each vehicle and performing statistical processing is stored in the parking information DB. When the destination is received from the car navigation system before traveling, the parking position at the destination is notified based on the priority order of the recommended parking lot information.

  When there are multiple parking positions corresponding to the facility, it is possible to guide to the parking position suitable for each shipping company, so there is no need to search for the parking position after arriving at the destination facility, which is convenient improves.

It is a block diagram of the parking position guidance system using this invention. It is a figure which shows the structure of the data stored in parking information DB. It is a figure which shows the example in case there exist a some parking position in a plant | facility. It is a flowchart which shows the whole process of a parking position guidance system. It is a figure which shows the car navigation screen which inputs parking information. It is a flowchart which shows the production | generation process of recommended parking lot information.

  FIG. 1 shows a configuration diagram of a parking position guidance system using the present invention. Each delivery vehicle 15 can communicate with the delivery center server 10 via the installed car navigation system 16. In the car navigation system 16 of the delivery vehicle 15, a travel log of the installed delivery vehicle 15 is acquired, and this travel log is transmitted from the car navigation system 16 to the delivery center server 10.

  The delivery center server 10 collects information such as the stop position and date / time recorded in the travel log sent from the car navigation 16 of each delivery vehicle 15 and accumulates it in the parking information DB 11 as probe data relating to the parking state. In addition, when there are a plurality of parking lots corresponding to the delivery destination, the parking information DB 11 also stores recommended parking lot information that stores the parking position to be used preferentially. Further, the delivery center server 10 determines a delivery route for each delivery vehicle 15 in consideration of the delivery destination, delivery time instructions, traffic information, and the like based on the data in the delivery destination scheduling DB 13.

  The parking lot instruction for parking at the delivery destination is estimated by the parking lot guidance processing unit 12 from the parking information DB 11 from the probe data stored for each parking lot, and the optimal parking lot in the arrival time zone is estimated. Send the location to the car navigation system. The parking space availability information of each delivery destination is estimated using the statistical data of the parking information DB 11, the information collected from the Web, and the parking space availability information 14 obtained from the parking lot administrator 14. Information is also taken into the parking information DB 11 and used.

  FIG. 2 is an example of probe data and recommended parking lot information stored in the parking information DB 11. FIG. 2A shows an accumulation example of probe data transmitted from the car navigation system 16 mounted on each delivery vehicle 15. FIG. 2B is an example of recommended parking lot information in which the recommended parking lots are prioritized for each shipping company. Each delivery vehicle belongs to one of the transportation companies managed by the parking position guidance system, and each probe data of the delivery vehicle 15 includes information on a unique navigation ID for each car navigation system 16. You can find out which transportation company the probe data belongs to. Therefore, the information on the parking position in the probe data of each delivery vehicle is statistically processed for each transportation company corresponding to the delivery vehicle determined from the navigation ID, so that the preference of the delivery vehicle driver belonging to each transportation company or each It becomes possible to prioritize parking positions that reflect the parking positions suitable for the conditions of deliverables handled by the shipping company.

  FIG. 3 is an example in which a plurality of parking positions exist in a delivery destination facility. In the case of the example shown in FIG. 3 (A), the delivery vehicle needs to deliver the delivery to the facility. Therefore, the delivery vehicle is not parked in the general parking lot facing the general entrance of the facility. Parking near the mouth is better for delivery work. On the other hand, in the case of the example as shown in FIG. 3B, there are a plurality of parking lots as in the first to third parking lots, and there are no specific entrances to the facilities that can be used. . Thus, even when there are a plurality of parking positions, there are cases where a more preferable entrance exists depending on the conditions of the delivered goods depending on the shipping company. Even if the driver acts to park the vehicle at a convenient parking lot or a parking lot near an appropriate entrance by his / her work, the parking position designated by the distribution center server 10 is inappropriate. Since it is expected that the actual parking position will be moved to a more appropriate location, priority is given to the delivery vehicle by creating the recommended parking lot information as shown in FIG. 2 (B) from the collected probe data. The order of parking lots to be guided can be determined in advance.

  FIG. 4 is a flowchart illustrating the flow of the entire operation management process for a delivery vehicle in the parking position guidance system using the present invention. First, in each delivery vehicle 15, the car navigation system 16 mounted on the delivery vehicle accepts an input of a destination from the driver before departure (S 40). The car navigation system 16 transmits the destination input by the driver to the delivery center server 10 together with its navigation ID number (S41).

  In the delivery center server 10 that has received the information on the destination of the delivery vehicle from the car navigation system 16, the parking lot guidance processing unit 12 discriminates the transportation company to which the vehicle equipped with this navigation belongs from the received navigation ID, and the transportation. It is checked whether the recommended parking lot information corresponding to the company exists in the parking information DB 11 of the delivery center server 10 (S42). If there is recommended parking lot information (S42: Yes), the position of the recommended parking lot with the highest priority at the destination received is obtained and returned to the car navigation system 16 as the recommended parking lot (S44). At this time, as described above, the parking space of the recommended parking lot is estimated by using the statistical data of the parking information DB 11 and the recommended parking lot with the highest priority except for the recommended parking lot that is expected to be full in the arrival time zone. You may make it transmit the position of a parking lot. As a result, it is possible to predict the full parking space information based on the parking position obtained from the probe data of the vehicle or the full parking space information of the actually parked parking lot, and to indicate a free parking position.

  In addition, in order to determine the shipping company to which the delivery vehicle equipped with the car navigation belongs, from the navigation ID, for each delivery vehicle 15 managed by the delivery center server 10, the navigation ID of the installed navigation and the transportation company belonging to the delivery vehicle. It is assumed that information is stored in the vehicle DB 17.

  The car navigation system 16 that has obtained the position of the recommended parking lot from the delivery center server 10 sets the recommended parking lot as the destination, performs route search, and starts route guidance using the obtained route (S45). On the other hand, when the recommended parking lot for the destination corresponding to the transportation company to which the vehicle belongs is not stored in the parking information DB 11 (S42: No), the recommended parking lot is not sent from the delivery center server 10, The car navigation system 16 performs route search for the destination input by the driver and starts route guidance (S43).

  After the information on the recommended parking lot is transmitted to the car navigation system 16, until the parking information after arrival at the destination is received from the car navigation system 16, that is, while the delivery car 15 is moving along the route guidance of the car navigation system 16, When the parking lot availability information 14 received from the outside monitors the full availability of the recommended parking lot transmitted to the car navigation system 16 (S46), and detects that the full availability has changed to become full. (S46: Yes), the next highest priority parking lot that is sent to the car navigation system 16 is contacted as a new recommended parking lot, and the corresponding car navigation system 16 is sent and the route is reset there. Yes (S47). As a result, the process returns to S45, and the car navigation system 16 that has received the information of the new recommended parking lot uses the route reset by the route search in which the position of the recommended parking lot obtained from the delivery center server 10 is set as the destination. Guidance starts. For example, when the recommended parking lot information as shown in FIG. 2B is stored, if the destination of the delivery vehicle belonging to the “transport company A” is “facility A”, the priority order is usually one. Guidance is provided from the highest first parking lot, but if the first parking lot becomes full while the delivery vehicle is moving, an instruction to move to the second parking lot with the next highest priority is sent. Similarly, when the second parking lot becomes full during the movement, an instruction to move to the third parking lot with the next highest priority is sent.

  In this way, when the parking space availability is predicted during arrival at the destination, and the availability information changes during route travel, it is possible to re-search for a better parking position and automatically change the routing. This makes it possible to provide detailed guidance with higher accuracy than the parking lot guidance.

  When the delivery vehicle 15 arrives at the recommended parking lot or the destination parking lot and then actually stops at the parking lot, the car navigation system 16 receives an input of parking information from the driver and transmits it to the delivery center server 10 (S48).

  FIG. 5 is a diagram showing a screen of the car navigation system 16 when inputting parking information. The items to be entered as parking information are the position 51 designated by operating the arrow 50 displayed on the map on the map with the location corresponding to the actual parking position, the parking date 52, the vehicle type 53 of the delivery vehicle 15, the arrival The parking space in the parked parking space 54, the priority order 55 of the parking position to be registered, the EV charger 56 indicating whether or not there is an EV charger at the parked parking position, the parking purpose 57, and the like.

  When the driver parks the delivery vehicle 15 at the parking lot, the parking information consisting of these items is converted into the latitude and longitude of the parking position designated on the map, and the destination and navigation ID are changed. It is transmitted to the delivery center server 10 as probe data relating to the added parking state, and stored in the parking information DB 11. As described above, by collecting the probe data obtained by adding the input information to the car navigation system 16 to the parking information of only the normal probe information including the latitude / longitude of the delivery vehicle 15 and the time information, the parking information DB 11 can be highly accurate. It becomes.

  FIG. 6 is a flowchart showing a process for generating recommended parking lot information for determining a recommended parking lot for each transportation company for a certain facility. In the recommended parking lot information generation processing, based on the parking information from each delivery vehicle 15 in the probe data accumulated in the parking information DB 11, the parking lot used for each destination facility is estimated from the stop position of the delivery vehicle. (S61). In the estimation of the parking lot, it is assumed that the parking lot closest to the parking position of the parking information is the parking place. Next, statistical processing of the probe data stored in the parking information DB 11 is performed for the parking facility estimated to be the destination facility (S62), and the number of vehicles used by each transportation company is calculated for each estimated parking lot. Count for each parking lot and determine the frequency of use. Further, for each parking lot, the full availability of each parking lot is estimated for each predetermined time zone from the parking date and time and vacancy information, and stored in the parking information DB 11 as with the recommended parking lot information. At this time, the full parking information of the parking lot full information 14 collected from the outside may be added to the collected parking information to estimate the full availability for each time zone in each parking lot.

  Based on the parking lot usage frequency obtained for each shipping company, the parking lot with the highest number of usages is prioritized as the recommended parking lot for that shipping company, and so on. The parking lots are prioritized for each combination (S63), and the result is stored in the parking information DB 11 as recommended parking lot information (S64).

  For example, it is assumed that a certain facility has a first parking lot, a second parking lot, and a third parking lot, and the second parking lot is close to the material entrance. It is preferable to recommend that the transportation company A be parked at the second parking lot when there is a lot of work handling large luggage. On the other hand, if the transportation company B mainly handles small parcels, it is preferable to park at the first parking lot close to the entrance 1 where the facility reception desk is located. In this case, the driver is expected to park more frequently in the parking lot desirable for his / her business, so the priority of the parking lot in the recommended parking lot information generated by the process shown in FIG. Will reflect the preferences of the driver or shipping company. In addition, even after the recommended parking information has been created, if the recommended parking is not suitable for actual work, the driver will search for a more appropriate parking and park it. By constantly collecting the parking information and reflecting it in the recommended parking information, an improper parking lot will be deceived, and as a result, it can be expected to be a preferred parking priority. In this way, it is important not only to estimate the parking lots but also to prioritize the use of the parking lots reflecting the business conditions for each shipping company.
