That is, the control unit 20 controls the user I/F unit (not shown) by the function of the parking position output unit 21b to display the map around the vehicle on the output unit and display the planned delivery route on the map. At this time, the control unit 20 refers to the parking position included in the planned delivery route and also displays information indicating the parking position where the vehicle should be parked when delivering the delivery to each delivery destination.

In this state, the control unit 20 controls the user I/F unit (not shown) to output the voice of the guidance (right turn guidance, etc.) necessary for driving the vehicle along the planned delivery route. In the above configuration, the parking position is specified based on the parking position information and the delivery information (details will be described later). Therefore, according to the present embodiment, the identified parking position is guided in consideration of the information regarding the delivery, and the delivery person who uses the parking position output terminal recognizes the identified parking position in consideration of the information regarding the delivery. can do.

It should be noted that the control unit 20 can acquire the estimated arrival time zone when the vehicle arrives at the delivery destination when the vehicle travels along the planned delivery route after the current location of the vehicle. That is, the control unit 20 can specify the estimated arrival time zone that will reach the delivery destination after the current location by acquiring the travel time required to travel each road section that constitutes the planned delivery route. The control unit 20 can transmit the estimated arrival time zone associated with each delivery destination to the parking position guidance system 100 via the communication unit 15.

The required travel time for each road section may be acquired by various methods. For example, the control unit 20 may determine the distance along the planned delivery route from the current position specified based on map information (not shown) to the delivery destination. The estimated arrival time zone can be specified by dividing by the average vehicle speed for each road section. The average vehicle speed may be a fixed value determined in advance, or may be determined according to the degree of congestion. Of course, the average vehicle speed may be determined for each road type. The estimated arrival time zone may be determined in various ranges, but in the present embodiment, it is one of the time zones divided every two hours. For example, time zones such as 8:00 to 10:00 and 10:00 to 12:00 are defined in advance for 24 hours.

(1-2) Configuration of parking position guidance system:
The parking position guidance system 100 includes a control unit 200 including a CPU, RAM, ROM, etc., a recording medium 300, and a communication unit 400. The communication unit 400 includes a circuit for exchanging information with the parking position output terminal 10 and the camera 50.

In this embodiment, the parking position guidance program 210 can be executed as this program.

Further, on the recording medium 300, map information 300a, parking position information 300b, delivery information 300c, and parking status information 300d are recorded. The map information 300a includes the same information as the map information recorded on the recording medium of the parking position output terminal 10, and includes the node data, the shape interpolation point data, the link data, the position of the road and the features existing around it, and the like. It includes the data shown. The link data is associated with information indicating the cost for each road section indicated by the link data. The data indicating a feature includes the attribute of the feature (type of facility, etc.). In this embodiment, these features can be the delivery destination.

Further, in this embodiment, the map information 300a includes information indicating roads that can be walked around the delivery destination. That is, the map information 300a includes node data indicating the end points of a road section that can be walked, shape interpolation data, link data, and data indicating the position of the delivery destination. Further, the link data is associated with information indicating the cost for each road section indicated by the link data.

Further, in the present embodiment, the parking position information 300b indicating the parking position used when delivering the delivery to the delivery destination is recorded in the recording medium 300 for each delivery destination. The parking position information 300b is information indicating a position candidate for parking a vehicle that delivers a delivery to the delivery destination, and is defined for each of the plurality of delivery destinations. Although the delivery destination is a store in the present embodiment, it goes without saying that the delivery destination may be a facility other than the store, such as a public facility or a private home.

In the present embodiment, the parking position candidates are defined for each mesh described above. That is, each rectangular area generated by dividing the two-dimensional plane into a grid is a parking position candidate. The grid includes a road on which a vehicle can be parked on the road for loading and unloading deliveries and a parking lot accessible from the road. In the present embodiment, the vehicle is parked on the road or the parking lot. It is supposed to do.

Of course, the parking position may be defined by a plurality of coordinates on the road, the coordinates of the parking lot, or the like, but in the present embodiment, the parking status is confirmed by the camera 50, and the parking position is unloaded. When parking for, a slight difference in coordinates does not make sense. Therefore, in the present embodiment, a configuration is adopted in which parking position candidates are defined in mesh units. The size of the mesh may be various according to the field of view of the camera 50, but in the present embodiment, a rectangle having a side of several meters is assumed.

Furthermore, in the present embodiment, the parking position information 300b includes a parking time period that is a time period in which the vehicle can be parked at the parking position. In other words, depending on the parking position, there are times when the vehicle can be used and times when the vehicle cannot be used because of consideration for the surrounding residents and noise prevention. Therefore, in the present embodiment, usable time zones are associated with the parking position information 300b. Therefore, the time zone not shown in the parking position information 300b is the unusable time zone. In the present embodiment, the time zones in which the parking position can be used are classified into three types, morning, daytime, and night, and the start time and end time of each time zone are predetermined. In the present embodiment, 4:00 to 10:00 is morning, 10:00 to 16:00 is daytime, and 16:00 to 4:00 is night. Of course, this division is an example.

Further, in the present embodiment, the parking position information 300b includes information in which the types of deliverable items are associated with the parking positions. In this embodiment, it is assumed that there are a plurality of types of deliveries. Specifically, in the present embodiment, the delivered product is a product to be sold in a store, and is a chilled product that needs to be stored at a low temperature (for example, 5° C. or lower or around 0° C.) as a food product (including a beverage). There are products, frozen products, and products that can be managed at room temperature. There are miscellaneous goods and magazines as products other than food products. In the present embodiment, the above five types of deliveries are assumed.

In the present embodiment, focusing on the fact that there is a type that requires temperature management among the types of deliveries, the parking position where the vehicle is parked when delivering the deliveries that should maintain a low temperature is set from the delivery destination. It is set to be within the default distance. That is, the parking position when the product requiring temperature control (chilled product and frozen product) is the delivery item, the parking position when delivering the delivery item to the delivery destination is selected from the delivery destinations. A parking position existing within a predetermined distance is selected.

The product that does not require temperature management is a parking position that is different from the parking position when the product that requires temperature management is a delivery. In the present embodiment, with respect to the parking position information 300b indicating the parking position, information indicating that a product that requires temperature management is a delivered product or information that indicates that a product that does not require temperature management is a delivered product is displayed. It is associated. In the present embodiment, each parking position is used to deliver either a product that requires temperature control or a product that does not require temperature control, but of course delivers a product that requires temperature control. The parking position used at this time may also be configured to be used at the time of delivery of a product for which temperature management is unnecessary.

Furthermore, in the present embodiment, the parking position information 300b includes information indicating a complaint occurrence point around the parking position. That is, when delivering a deliverable, complaints may occur from residents, etc. around the parking position due to various factors such as noise, an accident, the presence of a vehicle, etc. accompanying the delivery. In the present embodiment, a point (coordinates) where a complaint has occurred in the past is defined in advance as a complaint occurrence point and is associated with the parking position.

In the present embodiment, the complaint origin is associated with the cause of the complaint. Specifically, the cause of the complaint is classified into a complaint about the vehicle, a complaint about the occurrence of an accident, and a complaint about noise, and any one of them is associated with the complaint occurrence point. Further, the complaint occurrence points may be added at any time depending on the occurrence of complaints or the number of occurrences exceeding a threshold, and the points where complaints have not occurred for a predetermined period or more may be deleted.

FIG. 4A shows an example of the parking position information 300b. The rectangle shown in FIG. 4A indicates a mesh, and each mesh is a parking position. Although roads actually exist in each mesh, they are not shown in FIG. 4A. The delivery destination G is shown in the center mesh. The parking positions existing around the delivery destination G are schematically shown by a white mesh. The gray mesh is not a candidate for the parking position because it is far from the delivery destination G and there is no road to the delivery destination G.

Information associated with each parking position is shown in characters in the parking position candidate (white mesh) shown in FIG. 4A. That is, each of M, D, and N can use the parking position in the time zones of morning, daytime, and night, and it is prohibited to use the parking position in the time zone other than the time zone indicated by the letter. It indicates that

Each of Tn and Tc indicates a parking position when delivering a product that does not require temperature management, and a parking position when delivering a product that requires temperature management. C ₀ , C ₁ and C ₂ indicate the presence or absence of a complaint and the cause of the complaint, C ₀ indicates that the complaint occurrence point is not included, and C ₁ and C ₂ include the complaint occurrence point and are numerical values. It is shown that the causes of complaints are distinguished by. In addition, since the complaint occurrence point is defined by the coordinates in the present embodiment, the coordinates can be specified as well as being included in the parking position. F and V shown in FIG. 4A are parking status information indicating that the parking position is full and vacant, and the details will be described later.

The delivery information 300c is information about delivery, and is defined for each delivery person (may be a vehicle used by each delivery person). In the present embodiment, the delivery information 300c includes information on deliverables and information on delivery schedules. That is, the deliverables to be delivered by each deliverer are determined at the stage when the delivery plan is established, and the deliverables and the delivery schedules differ depending on the deliverers, and thus information indicating these is defined as delivery information 300c.

Specifically, the information about the delivered item includes information (address) indicating the delivery destination of each delivered item and information indicating the type of each delivered item. In addition, the information about the delivery schedule includes the designated delivery time zone designated as the time zone in which the delivery should be delivered, and the estimated arrival time zone of the vehicle at the delivery destination scheduled before the departure of the vehicle. There is. Further, after the departure of the vehicle, the estimated arrival time zone of the vehicle at the delivery destination is acquired and recorded as the delivery information 300c. That is, in this embodiment, the time zone in which a specific delivery is to be delivered to a specific delivery destination may be specified depending on various circumstances such as the circumstances of the store serving as the delivery destination and the circumstances of distribution. In this embodiment, the scheduled departure time zone and the estimated arrival time at each delivery destination are set so that all deliverables can be delivered while delivering the deliverables in which the time zone to be delivered is specified within the time zone. A scheduled delivery route with a obi is determined.

Therefore, in order to make it possible to formulate such a scheduled delivery route, when there is a delivery item in which a time period to be delivered is designated, the delivery designated time period is associated with the delivery item. The designated delivery time zone may be determined in various ranges, but in the present embodiment, it is any one of the time zones divided every two hours. For example, time zones such as 8:00 to 10:00 and 10:00 to 12:00 are defined in advance for 24 hours.

Furthermore, the information regarding the delivery schedule includes the estimated time of arrival of the vehicle at the delivery destination acquired before the departure of the vehicle. That is, when the planned delivery route is searched, the control unit 200 acquires the distance of each section that constitutes the planned delivery route based on the map information 300a, and divides the distance by the average vehicle speed to drive each section. Get the time required. The average vehicle speed may be a fixed value determined in advance, or may be determined according to the degree of congestion. Of course, the average vehicle speed may be determined for each road type.

In any case, the control unit 200 determines the time zone including the time when the vehicle arrives at each parking position by acquiring the travel required time for each section to reach each parking position after the departure point. Acquire as the estimated time of arrival. The obtained estimated time of arrival is associated with the delivery person and each delivery destination, and is recorded on the recording medium 300 as delivery information 300c. The expected arrival time zone may be determined in various ranges, but in the present embodiment, it is one of the time zones divided every two hours. For example, time zones such as 8:00 to 10:00 and 10:00 to 12:00 are defined in advance for 24 hours. Of course, the scheduled loading/unloading time at each parking position may be taken into consideration in order to obtain the estimated arrival time zone.

Furthermore, when the estimated arrival time zone is transmitted from the parking position output terminal 10 after the departure of the vehicle, the control section 200 acquires the estimated arrival time zone via the communication section 400. Then, the delivery person is identified based on the parking position output terminal 10 that was the transmission source of the estimated arrival time zone, and the estimated arrival time zone is associated with each delivery destination of the delivery person and recorded as the delivery information 300c. It is recorded on the medium 300. It should be noted that in the present embodiment, the estimated arrival time zone is the time zone specified at the stage of formulating the scheduled delivery route before the departure of the vehicle, and the estimated arrival time zone is the time when the delivery situation of the vehicle changes after the departure. It is the time zone acquired by

The parking status information 300d is information indicating whether or not the parking position is vacant. In the present embodiment, the parking status information 300d is information for each parking position and is defined for each mesh described above. That is, the image captured by the camera 50 includes an image of a road or a parking lot where the vehicle can be temporarily parked on the road, and the image of the upper part of the image is analyzed to analyze the road or the road. It is possible to determine whether the vehicle is parked in the parking lot.

Specifically, the control unit 200 identifies the image of the road or parking lot from the images of the cameras via the communication unit 400. The image of the road or the parking lot may be specified based on the feature amount of the image, or it may be specified in advance that the road or the parking lot exists at a specific position in the image of the camera 50 fixed to the installation position. It may be. In any case, the control unit 200 determines that the parking position is not empty when there is an image having the characteristics of the vehicle above the image of the road or the parking lot, and when there is no image having the characteristics of the vehicle. It is determined that the parking position is empty.

When there are a plurality of points where parking is possible within one mesh, various methods may be used to specify whether or not the parking position is vacant. For example, the configuration may be such that it is determined that the parking position is not vacant when the ratio of the points where the vehicle is parked among a plurality of points is equal to or more than a threshold value. It is possible to adopt a configuration in which it is determined that the position is vacant. That is, it may be determined whether or not the parking position is vacant based on a predetermined standard.

The control unit 200 can acquire an image obtained by photographing the parking position from the camera 50 at an arbitrary timing, and can acquire information indicating whether or not each parking position is vacant. Then, the control unit 200 associates the information indicating each parking position with the information indicating whether or not the parking position is vacant, and causes the recording medium 300 to record the information as parking status information 300d. When the parking status information 300d is acquired for the parking position existing around the delivery destination G shown in FIG. 4A, as shown in FIG. 4A, it indicates that each mesh is F or that the mesh is empty. V is in the associated state.

In the present embodiment, the map information 300a includes information indicating roads that can be used when walking. In the present embodiment, the information is also defined for each area divided by the mesh. The size of the mesh may be the same as or different from the size of the mesh indicating the parking position information 300b. In the present embodiment, the road may be determined to be unusable when a complaint is generated from the surrounding residents. Further, since the presence or absence of complaints may vary depending on the time zone, in the present embodiment, the road is regarded as unusable during the time zone when the complaint occurs.

That is, the time zone during which the use of the road included in each mesh is not permitted is defined, and is recorded in the map information 300a in association with each mesh together with the coordinates of the complaint occurrence point and the cause of the complaint. FIG. 5A shows an example of information associated with meshes. The rectangle shown in FIG. 5A shows a mesh set for a road used for walking, and the road section indicated by the map information 300a exists in each mesh (the road is not shown in FIG. 5A). In FIG. 5A, the delivery destination is G and the vehicle parking position is S.

In addition, in the present embodiment, the time zone during which the road cannot be used is defined by any of morning, daytime, and night, like the parking position. In FIG. 5A, morning, noon, and night are indicated by M, D, and N, respectively. In addition, in the process of carrying the delivered material on foot, various factors such as noise generated by the dolly and contact with the delivery person may cause complaints from residents around the walking route. In the present embodiment, points (coordinates) where complaints have occurred in the past are defined in advance as complaint occurrence points, and causes of complaints are associated. In FIG. 5A, the difference in the cause of the complaint is shown by distinguishing the signs such as C ₀ , C ₁ and C ₂ .

The code C ₀ indicates that there is no complaint occurrence point. Therefore, in the mesh associated with the code C _0, there is no time zone in which the road is unusable. It should be noted that the complaint occurrence points may be added at any time depending on the occurrence of complaints or the number of occurrences exceeding a threshold value, or the points where no complaints occurred may be deleted.

In the present embodiment, the control unit 200 executes the parking position guidance program 210 to guide the parking position to each user of the parking position output terminal 10. In order to realize the guidance, the parking position guidance program 210 includes a parking position information acquisition unit 210a, a delivery information acquisition unit 210b, a parking status information acquisition unit 210c, a parking position specification unit 210d, and a parking position guidance unit 210e. ..

That is, the control unit 200 refers to the parking position information 300b, and for each of the parking positions associated with an arbitrary delivery destination of the delivery person who uses the arbitrary parking position output terminal 10, the parking time period and the kind of the delivery. , You can get the complaint point.

The delivery information acquisition unit 210b is a program module that causes the control unit 200 to execute a function of acquiring delivery information regarding delivery. That is, the control unit 200 refers to the delivery information 300c and refers to the delivery information corresponding to the delivery person who uses the arbitrary parking position output terminal 10, that is, the delivery address of the delivery, the type of delivery, and the delivery. Information about delivery schedule (designated delivery time zone, estimated arrival time zone, estimated arrival time zone) can be acquired.

The parking status information acquisition unit 210c is a program module that causes the control unit 200 to execute a function of acquiring parking status information indicating whether or not the parking position is vacant. That is, the control unit 200 indicates that the parking position information 300d indicates the parking position candidates for the parking positions at which the vehicle should be parked when the delivery person who uses the arbitrary parking position output terminal 10 delivers the delivery to the delivery destination. Acquires information indicating whether or not it is vacant.

The parking position specifying unit 210d is a program module that causes the control unit 200 to execute a function of specifying the parking position where the vehicle is parked when delivering the delivery based on the parking position information 300b and the delivery information. That is, the control unit 200 identifies the delivery destination of the deliverable to be delivered by the delivery person who is the target of the planned delivery route, based on the delivery information 300c. Further, the control unit 200 identifies the designated delivery time zone of each delivery based on the delivery information 300c. Then, the control unit 200 refers to the map information 300a, searches for a route for delivering the delivery to the delivery destination within the designated delivery time zone, and acquires the route as the scheduled delivery route.

Note that the route search may be performed by various methods, and for example, the Dijkstra method, the A* algorithm, and their improved algorithms can be adopted. The control unit 200 can acquire the estimated time of arrival at the delivery destination by acquiring the required travel time based on the distance of the road section indicated by the map information 300a. That is, in the present embodiment, the average vehicle speed for each road section is predetermined, and the required travel period of the road section can be obtained by dividing the distance of the road section by the average vehicle speed. Therefore, the required travel period of the route can be acquired by accumulating the required travel periods of the road sections that form the route.

Therefore, the control unit 200 performs a route search on the delivery destination of the delivery for which the designated delivery time zone is determined by imposing a constraint condition such that the vehicle reaches the parking position within the designated delivery time zone. In addition, for a delivery item for which a designated delivery time period is not determined, for example, route search is performed by delivering the items in order of decreasing distance. If necessary to meet the designated delivery time zone, processing such as changing the delivery order of deliveries for which the designated delivery time zone is not determined is performed as appropriate. In any case, the control unit 200 departs so that all the deliverables can be delivered while delivering within the designated delivery time period for the deliverables for which the designated delivery time period is determined by the above-described processing. The scheduled time zone is determined, and the scheduled delivery route including the scheduled arrival time zone at the delivery destination is established.

In any case, once the planned delivery route is established, the delivery destination for which the delivery time zone is specified reaches the delivery destination during the delivery time zone specified, and the delivery time zone is not specified. For the delivery destination, the scheduled delivery route is set so that the delivery destination is reached during the estimated arrival time.

It should be noted that at the time of route search, the control unit 200 does not set each delivery destination as a destination, but searches a route whose destination is a parking position selected from parking position candidates associated with each delivery destination. To do. Therefore, the control unit 200 selects the parking position based on the parking position information 300b, the delivery information 300c, and the parking status information 300d. Specifically, the control unit 200 selects a parking position in which the designated delivery time period is included in the parking time period for the delivery destination for which the delivery time period is designated. In the present embodiment, the parking time zone is defined by any of morning, daytime, and night, and the designated delivery time zone is defined by every two hours. Therefore, the control unit 200 determines whether the designated delivery time zone is included in the morning, daytime, or night, and selects the parking position associated with the parking time zone including the designated delivery time zone.

For example, in the example shown in FIG. 4A, the parking available time zone (M, D, N) is associated with the parking position as the parking position information 300b. In this example, when the designated delivery time zone is 6:00 to 8:00, 8:00 to 10:00, etc., these time zones are included in the morning parking time zone. Therefore, in the example shown in FIG. 4A, when the designated delivery time period is these time periods, the parking position in which the parking time period indicated by the parking position information 300b is morning (M) is selected.

With respect to the delivery destination for which the delivery time zone is not designated, the control unit 200 selects a parking position in which the expected arrival time zone is included in the parking time zone. In the present embodiment, the parking time zone is defined by any of morning, daytime, and night, and the expected arrival time zone is defined by every two hours. Therefore, the control unit 200 determines whether the scheduled arrival time zone is included in the morning, daytime, or night, and selects the parking position associated with the parking time zone including the scheduled arrival time zone.

For example, in the example shown in FIG. 4A, the parking available time zone (M, D, N) is associated with the parking position as the parking position information 300b. In this example, when the scheduled arrival time zone is 6:00 to 8:00, 8:00 to 10:00, etc., these time zones are included in the morning parking time zone. Therefore, in the example shown in FIG. 4A, when the estimated arrival time period is these time periods, the parking position in which the parking time period indicated by the parking position information 300b is morning (M) is selected.

Next, the control unit 200 selects, from the selected parking positions, a parking position that is associated with the type of deliverable to be delivered to the delivery destination. For example, in the example illustrated in FIG. 4A, when the type of the delivery to the delivery destination G is chilled, the control unit 200 controls the parking position information 300b at the parking position when delivering a product requiring temperature management. The parking position (the parking position to which Tc is associated) associated with the information indicating that is selected.

Further, the control unit 200 selects a parking position to which the complaint occurrence point is not associated from the selected parking positions. For example, in the example shown in FIG. 4A, the control unit 200 selects the parking position associated with C ₀ indicating that the complaint occurrence point is not included.

Further, the control unit 200 selects an empty parking position indicated by the parking status information from the selected parking positions. For example, in the example shown in FIG. 4A, the control unit 200 selects the parking position associated with V indicating that the parking position is vacant. FIG. 4B shows the parking positions selected by the thick solid line, as described above, depending on the parking time period, the type of delivery, the presence or absence of the complaint point, and the empty state.

The parking position selected as described above can deliver the delivered product regardless of the parking position. Therefore, the control unit 200 may select an arbitrary position from these parking positions. In the present embodiment, the control unit 200 selects the parking position closest to the delivery destination G (P ₁ shown in FIG. 4) as the parking position in order to reduce the required delivery period. In addition, at the time of route search, one point in the selected parking position may be set as the destination, for example, a point at the center of the parking position, one point on the road where road parking is possible, a parking lot, etc. Is set as the destination.

As described above, the control unit 200 performs the process of identifying the parking position where the vehicle should be parked when delivering the delivery to the delivery destination, for each of the delivery destinations. When the parking position is specified for all the deliverables to be delivered by the delivery person, the control unit 200 searches for a planned delivery route having the parking position as a destination. That is, the control unit 200 specifies the departure time zone so that the vehicle reaches the parking position within the delivery specified time zone of the delivery, and delivers each delivery. A planned delivery route that sequentially arrives at a parking position (for example, one point such as the center in the mesh) is searched.

The control unit 200 acquires the estimated arrival time zone at which the vehicle arrives at the parking position when the vehicle travels according to the scheduled delivery route for the deliverable for which the delivery time is not specified. Then, the control unit 200 associates the expected arrival time zone with the delivery destination for the delivery item whose delivery time is not specified.

The parking position guide unit 210e is a program module that causes the control unit 200 to execute a function of guiding the specified parking position. That is, in the present embodiment, the control unit 200 guides the parking position by causing the parking position output terminal 10 to output the scheduled delivery route including the parking position. Therefore, the control unit 200 transmits the scheduled delivery route to the parking position output terminal 10 used by the delivery person, via the communication unit 400. As a result, at the parking position output terminal 10, the planned delivery route for reaching the parking position is guided.

In the above configuration, the control unit 200 identifies the parking position based on the delivery information. Therefore, it is possible to specify the parking position in consideration of the information about the delivery such as the kind of the delivered product, the designated delivery time period and the estimated arrival time period.

(2) Parking position output processing and parking position guidance processing:
Next, the parking position output process executed by the control unit 20 and the parking position guidance process executed by the control unit 200 will be described. 2 and 3 are flowcharts of the parking position output process and the parking position guidance process. The parking position output process is executed by the parking position output terminal 10 used by each delivery person, and the parking position guidance process is executed for each delivery person in the parking position guidance system 100. A series of processes will be described by focusing on the delivery person.

In the parking position guidance system 100, the parking position guidance process is started by various triggers (for example, a request from the parking position output terminal 10 or a request from the delivery manager). When the parking position guidance process is started, the control unit 200 acquires the scheduled delivery route by the function of the parking position specifying unit 210d (step S100). Here, the control unit 200 identifies the parking position based on the parking position information, the delivery information, and the parking status information acquired by the functions of the parking position information acquisition unit 210a, the delivery information acquisition unit 210b, and the parking status information acquisition unit 210c. , Get scheduled delivery routes to reach each parking position.

Specifically, the control unit 200 acquires the delivery information 300b by the function of the delivery information acquisition unit 210b, and acquires the address of the delivery destination of the deliverable to be delivered by the delivery person. Further, the control unit 200 acquires, based on the delivery information 300b, the deliverable for which the designated delivery time period is designated from among the deliveries. When there are deliveries for which the designated delivery time zone is specified, the control unit 200 tentatively determines the delivery order of these deliveries in ascending order of the designated delivery time zone. At this time, when there are a plurality of delivery destinations having the same designated delivery time zone, the order of closer distance from the departure place (delivery center or the like) is provisionally determined as the delivery order. Further, the control unit 200 tentatively searches for a route from the departure place of the vehicle to each delivery destination in the delivery order based on the map information 300a.

Further, the control unit 200 acquires the travel time required for traveling in each section (section between the departure place and the delivery destination, section between the delivery destinations, etc.) in the temporarily searched route. Then, the departure time from the departure place is determined so that the first delivery destination arrives within the designated delivery time period. After that, the control unit 200 acquires the arrival time at each delivery destination based on the travel time required in each section after the departure place, and determines whether the arrival time at each delivery destination is within the designated delivery time zone. To confirm. Here, when there is a delivery destination whose arrival time is not within the designated delivery time period, the control unit 200 excludes one or more delivery destinations and allocates it to another delivery person, and all the other delivery destinations. Make sure that your arrival time is within the designated delivery time.

When the arrival times at all the delivery destinations are within the designated delivery time zone, the control unit 200 tentatively determines the delivery order of other deliveries for which the designated delivery time zone is not designated. At this time, when the control unit 200 travels toward the delivery destination in the temporarily set delivery order, the control unit 200 can arrive at the delivery destination of the delivery item having the designated delivery time zone within the designated delivery time period. Whether or not it is determined based on the required travel time. Then, the control unit 200 determines the delivery order when the designated delivery time zone can reach the delivery destination of the designated delivery within the designated delivery time zone. When the designated delivery time zone cannot reach the delivery destination of the designated delivery within the designated delivery time zone, the control unit 200 repeats the tentative determination of the delivery order and the determination of the required travel time, and the delivery time zone is determined. The delivery order is determined so that the designated delivery destination can be reached within the designated delivery time period. That is, the control unit 200 fixes the delivery order so that the time zone of arriving at the delivery destination becomes the designated delivery time zone when delivering the delivery article for which the designated delivery time zone is designated, and the remaining delivery items are delivered. Determine the delivery order.

When the delivery order is set, the control unit 200 schedules the arrival when the destination when delivering to each delivery destination is each representative point of the parking position (for example, on the road closest to the center of the mesh). Get the time zone for each parking position. Since the respective parking positions are close to each other, the estimated time of arrival at each parking position may have a common value (for example, the estimated time of arrival when the delivery destination is the destination). Then, the control unit 200 selects and determines a parking position at which the vehicle is parked when delivering the delivery to each delivery destination from the candidates. That is, the control unit 200 refers to the parking position information 300b by the function of the parking position information acquisition unit 210a, and determines the parking time period, the type of delivery item, and the presence or absence of a complaint point for each parking position associated with each delivery destination. get. In addition, the control unit 200 refers to the parking status information 300c by the function of the parking status information acquisition unit 210c, and acquires a full state at each parking position associated with each delivery destination.

Then, the control unit 200 includes the designated delivery time zone or the estimated arrival time zone at each delivery destination in the parking time zone, and the type of the delivered article matches the type of the delivered article associated with the parking position. There is no complaint point, and an empty parking position is selected. As a result, when a plurality of parking positions are acquired, the parking position closest to the delivery destination is selected. For example, in the example shown in FIG. 4A, the parking position P ₁ is selected when the scheduled arrival time is in the morning and the delivery is of a type that requires temperature control. As described above, the control unit 200 performs the process of specifying the parking position where the vehicle should be parked when delivering the delivery to the delivery destination for each of the delivery destinations. When the parking position is specified for all the deliveries to be delivered by the delivery person, the control unit 200 searches for a planned delivery route having the parking position as a destination. That is, the control unit 200 searches for a route for delivering each delivery in the delivery order set as described above. When the route is searched, the control unit 200 associates each delivery destination with an estimated arrival time zone (or a designated delivery time zone when a delivery time is designated) to obtain information indicating the expected delivery route. ..

Next, the control unit 200 transmits the planned delivery route (step S105). That is, the control unit 200 sends the planned delivery route via the communication unit 400 to the destination of the parking position output terminal 10 used by the delivery person who performs the delivery along the planned delivery route. In this case, in the parking position output terminal 10 that is the transmission destination, the control unit 20 receives the planned delivery route via the communication unit 15 by the function of the parking position acquisition unit 21a (step S200), and the control unit 20 The route guidance is executed by the function of the parking position output unit 21b (step S205).

That is, the control unit 20 identifies the current position of the vehicle based on the output signals of the GNSS receiving unit 16, the vehicle speed sensor 17, and the gyro sensor 18, and the user I/F (not shown) displays a map around the current position based on map information (not shown). Is displayed. At this time, the control unit 20 distinguishes and displays the road section that is the planned delivery route from other road sections. Further, the control unit 20 changes the display range of the map in synchronization with the change of the current position of the vehicle, and indicates the planned delivery route in the traveling direction of the vehicle to the delivery person.

As a result, the parking position output terminal 10 provides route guidance of scheduled delivery routes that sequentially reach a plurality of delivery destinations. Therefore, in the process of route guidance, the route to the parking position where the vehicle should be parked is guided when going to the delivery destination for the next delivery, and when the vehicle reaches the parking position, the route guidance to the parking position ends. To do. Then, after the delivery person has delivered the delivery to the delivery destination and then starts driving the vehicle again, the route to the parking position where the vehicle should be parked when the vehicle goes to the delivery destination to be delivered next is guided.

In the present embodiment, in the process of performing such route guidance, if there is a case where the parking position to be parked next should be changed depending on the delivery situation, the parking position after the change is guided. Is becoming Therefore, the control unit 20 waits until it is determined by the function of the parking position output unit 21b that the distance to the delivery destination is the first distance or less (step S210). That is, the parking position may be reached earlier or later than initially planned due to traffic congestion, various troubles, and the like that occur during the delivery process. Therefore, in the present embodiment, after approaching the parking position to some extent, it is determined whether or not the schedule should be changed, and the first distance for determining whether the vehicle approaches the parking position or not. (For example, 3000 m) is predetermined.

The control unit 20 refers to map information (not shown), obtains the distance from the current position of the vehicle to the parking position as the next destination, and when the distance is the first distance or less, the distance to the delivery destination is It is determined that the distance is equal to or less than the first distance. When it is determined in step S210 that the distance to the delivery destination is the first distance or less, the control unit 20 acquires the estimated arrival time zone by the function of the parking position output unit 21b (step S215). That is, the control unit 20 obtains the travel time required to travel each road section that constitutes the planned delivery route from the current position to the next parking position, and adds it to the current time to arrive at the next parking position. Identify the estimated time zone.

Next, the control unit 20 transmits a request for the peripheral delivery route by the function of the parking position output unit 21b (step S220). That is, in the present embodiment, when approaching the parking position, the display of the route guidance on the parking position output terminal 10 is switched from the normal route guidance of the scheduled delivery route to the route guidance of the peripheral delivery route. The peripheral delivery route is information indicating a route around the parking position. When the parking position is changed according to the delivery situation, the peripheral delivery route indicates the changed parking position and the peripheral route. In the present embodiment, since the peripheral delivery route is generated by the parking position guidance system 100, the control unit 20 sends a transmission request for the peripheral delivery route to the parking position guidance system 100 via the communication unit 15. Send. At this time, the control unit 20 transmits the estimated arrival time zone acquired in step S215 by including it in the request for the peripheral delivery route.

In the parking position guidance system 100, the control unit 200 waits until it is determined that the request for the peripheral delivery route has been received (step S110). When it is determined in step S110 that the request for the peripheral delivery route has been received, the control unit 200 acquires the estimated arrival time zone via the communication unit 400 (step S115). That is, the control unit 200 acquires the estimated arrival time zone included in the request for the peripheral delivery route.

Next, the control unit 200 determines, by the function of the parking position specifying unit 210d, whether or not the estimated arrival time zone and the estimated arrival time zone match (step 120). That is, the control unit 200 determines whether or not the estimated time of arrival at the next delivery destination acquired before departure matches the estimated time of arrival estimated according to the situation after departure.

When it is not determined in step S120 that the estimated arrival time zone and the estimated arrival time zone match (that is, when the estimated arrival time zone and the estimated arrival time zone are different), the control unit 200 changes the parking position (step). S125). Specifically, the control unit 200 identifies a parking position in which the estimated arrival time zone is included in the parking time zone, and sets the parking position as a new parking position. That is, the control unit 200 refers to the parking position information 300b by the function of the parking position information acquisition unit 210a, and checks the parking time zone, the type of delivery, and the presence or absence of a complaint point for each parking position associated with the next delivery destination. To get. In addition, the control unit 200 refers to the parking status information 300c by the function of the parking status information acquisition unit 210c, and acquires the full state for each parking position associated with the next delivery destination.

Then, the control unit 200 includes the estimated arrival time zone of the next delivery destination in the parking time zone, and the type of the delivered article matches the type of the delivered article associated with the parking position. , No complaint point exists, select an empty parking position. As a result, when a plurality of parking positions are acquired, the parking position closest to the delivery destination is selected. For example, in FIG. 4B, the original parking position was P ₁ and the estimated arrival time was in the morning (M), but the estimated arrival time after departure was 10:00 to 12:00, and the daytime parking time was set. Let's assume an example. In this case, for example, P ₂ is selected as the nearest parking position from the objects whose parking time period is daytime and other conditions match the original parking position P ₁ . In the present embodiment, the parking position is changed based on the estimated arrival time zone, but it is needless to say that the parking position may be changed due to a change of the parking position in a full state, a new complaint, or the like. For example, in the former case, the control unit 200 determines whether or not the parking position selected before departure is full when the distance to the delivery destination becomes the first distance or less, and the vehicle is full. If so, it is possible to adopt a configuration in which the parking position of an empty vehicle is changed.

When it is determined in step S120 that the estimated arrival time zone and the estimated arrival time zone match, the control unit 200 skips step S125. In addition, for a delivery for which a designated delivery time zone for delivering the delivery is designated, if the designated delivery time zone does not match the estimated arrival time zone, it may not be possible to deliver within the designated delivery time zone. .. Therefore, it is preferable that the scheduled delivery route is set so that the designated delivery time slot does not coincide with the estimated arrival time slot for the deliverable in which the delivery time slot is designated. For example, with respect to a delivered product in which a time zone to be delivered is designated, a configuration in which priorities are set in the delivery order so that the delivery is completed as soon as possible after the start of the designated delivery time zone can be given. In addition, for deliveries with designated time zones for delivery, the estimated arrival time zone is acquired before the distance to the delivery destination is less than or equal to the first distance, and the designated delivery time zone is the estimated arrival time zone. It is possible to adopt a configuration such as changing the delivery order when they do not match.

Next, the control unit 200 acquires the peripheral delivery route by the function of the parking position specifying unit 210d (step S130). In the present embodiment, the peripheral delivery route is composed of a route from the current position to a parking position where the vehicle is parked when delivering to the next delivery destination, and a walking route from the parking position to the delivery destination. ..

When it is determined in step S120 that the expected arrival time zone and the estimated arrival time zone match, the control unit 200 delivers from the current location to the next delivery destination based on the scheduled delivery route established before departure. In this case, the route to the parking position where the vehicle is parked is specified. On the other hand, if it is not determined in step S120 that the expected arrival time zone and the estimated arrival time zone match, and the parking position is changed in step S125, the control unit 200 re-searches for a route to the next delivery destination. ..

That is, the control unit 200 refers to the map information 300a and searches for a route from the current position to the parking position changed in step S125. Here again, at the time of route search, one point in the parking position after being changed in step S125 may be set as the destination, and for example, the central point of the parking position or on the road where road parking is possible. A point in time or a parking lot is set as a destination.

Further, the control unit 200 searches for a moving route on foot from the parking position to the delivery destination. That is, the control unit 200 refers to the map information 300a, and acquires the information about the roads that can be walked and are defined for each mesh around the delivery destination. In addition, the control unit 200 specifies whether the estimated arrival time at the parking position is included in the morning, the day, or the night. Further, the control unit 200 selects a road mesh that can be used in the estimated arrival time zone. Then, the control unit 200 refers to the map information 300a and searches for a walking movement route from the selected mesh.

For example, in the example illustrated in FIG. 5A, when the estimated arrival time zone is morning, the control unit 200 determines that the mesh (day (D) or night where the morning (M) is not associated with the unavailable time zone). (A mesh corresponding to (N) can be selected) and a mesh (C ₀ ) having no complaint occurrence point is selected. As a result, a mesh having an arrow indicated by a thick solid line or a broken line in FIG. 5B is selected. When the control unit 200 searches for a travel route by walking from the roads in the selected mesh, for example, the broken line arrow is excluded from the candidates in the example shown in FIG. 5B, and the solid line arrow finally becomes the walk travel route. ..

When the peripheral delivery route including the route from the current position to the parking position and the walking movement route from the parking position to the delivery destination is acquired, the control unit 200 causes each parking position around the delivery destination based on the delivery information 300c. Acquires the complaint occurrence point included in and associates it with the peripheral delivery route. Then, the control unit 200 transmits the peripheral delivery route via the communication unit 400 by the function of the parking position guide unit 210e (step S135). When the peripheral delivery route is transmitted, the control unit 20 of the parking position output terminal 10 receives the peripheral delivery route via the communication unit 15 by the function of the parking position acquisition unit 21a (step S225).

Next, the control unit 20 waits until it is determined that the distance to the delivery destination is the second distance or less by the function of the parking position output unit 21b (step S230). Here, the second distance is a value smaller than the first distance, and is a threshold value for determining whether or not to guide the peripheral delivery route including the complaint occurrence point and the like.

When it is determined in step S230 that the distance to the delivery destination is the second distance or less, the control unit 20 executes the peripheral delivery route guidance by the function of the parking position output unit 21b (step S235). Here, in the peripheral delivery route guidance, before the distance to the delivery destination becomes equal to or less than the second distance, guidance indicating the planned delivery route by a map of a narrower area than the map displayed by the user I/F unit (not shown) Is.

Therefore, the control unit 20 changes the scale of the map so as to display a narrower map, and draws a map around the current position of the vehicle with reference to map information (not shown). Then, the control unit 20 distinguishes the route from the current position to the parking position from other roads and displays the route on the map. Further, in the present embodiment, the control unit 20 acquires the complaint occurrence point associated with the peripheral delivery route and displays it on the map in an overlapping manner. As a result, the parking position where the complaint occurrence point is not associated and the parking position where the complaint occurrence point is associated are guided in a distinguished state.

FIG. 4C is a diagram showing an example of peripheral delivery route guidance. In FIG. 4C, a map displayed on the display unit of the user I/F unit is schematically shown, a thick solid line indicates a road, and a thin broken line indicates a parking position candidate (mesh). The path is indicated by a thick broken line. Further, in FIG. 4C, the delivery destination is G, and the parking position (mesh) selected as the point where the vehicle is parked when delivering to the delivery destination is shown in gray. Therefore, the delivery person can recognize from the guidance shown in FIG. 4C that the vehicle should be parked at the position P, for example.

Further, in FIG. 4C, the complaint occurrence point is indicated by X. The complaint occurrence point is indicated by a different icon for each factor. That is, the cause differs between the complaint occurrence point where only X is displayed and the complaint occurrence point where X is displayed in the rectangle. With the guidance of the complaint occurrence point, the delivery person can avoid the complaint occurrence point, approach the parking position, or carefully drive near the complaint occurrence point. Further, even when the vehicle is parked at a parking position other than the gray parking position selected as the destination, the vehicle can be prevented from being parked at the complaint occurrence point.

Next, the control unit 20 waits until it is determined that the vehicle has arrived at the parking position (step S240). That is, the control unit 20 determines that the vehicle has arrived at the parking position when the mesh at the parking position includes the current position of the vehicle. When it is determined in step S240 that the vehicle has arrived at the parking position, the control unit 20 executes the walking movement route guidance by the function of the parking position output unit 21b (step S245). That is, the control unit 20 changes the scale of the map so as to display the map at a scale for displaying the walking route, and draws a map around the current position of the vehicle with reference to map information (not shown). Then, the control unit 20 distinguishes the route from the position where the vehicle is parked (the position where the movement of the vehicle is temporarily stopped) to the delivery destination from other roads and displays the route on the map. Further, in the present embodiment, the control unit 20 acquires the complaint occurrence point and displays it on the map in an overlapping manner. As a result, the delivery person can recognize the complaint occurrence point that should be noted or avoided in the process of walking.

FIG. 5C is a diagram showing an example of walking route guidance. In FIG. 5C, the map displayed on the display unit of the user I/F unit is schematically illustrated, the solid line indicates the road, and the thin broken line indicates the mesh of the road which can be walked. A walking path is indicated by a broken line. Further, in FIG. 5C, the delivery destination is G and the vehicle is parked at P. With such guidance, the delivery person can recognize the route from the position P to the delivery destination G.

Furthermore, in FIG. 5C, the complaint occurrence point is indicated by Z. The complaint occurrence point is indicated by a different icon for each factor. That is, the cause differs between the complaint occurrence point where only Z is displayed and the complaint occurrence point where Z is displayed in the rectangle. By the guidance of the complaint occurrence point, the delivery person can avoid the complaint occurrence point, move carefully, or move near the complaint occurrence point.

During the course of the walking route guidance, the control unit 20 waits until it is determined that the vehicle has restarted (step S250). Here, whether or not the vehicle has restarted may be determined by various methods. For example, a configuration in which it is determined that the vehicle has restarted when the movement speed of the current position is a movement that can be regarded as the speed of the vehicle, when the movement locus of the current position matches the shape of the roadway, or by a user instruction or the like. May be adopted.

When it is determined that the vehicle has restarted, the control unit 20 determines whether the delivery is completed (step S255). That is, when the delivery destination immediately before re-starting is the final delivery destination, the control unit 20 determines that the delivery is completed. When it is not determined that the delivery is completed in step S255, the control unit 20 repeats the processing of step S210 and the subsequent steps. When it is determined in step S255 that the delivery is completed, the control unit 20 ends the parking position output process.

(3) Other embodiments:
The above embodiment is an example for carrying out the present invention, and various other embodiments can be adopted as long as the parking position is specified based on the parking position information and the delivery information. For example, the guidance shown in FIG. 4C is an example, and the parking position may be guided at specific coordinates or the walking movement route may be simultaneously guided. Further, the guidance shown in FIG. 5C is an example, and for example, the delivery entrance of the delivery destination G may be guided on the map. Furthermore, a caution point other than the complaint (for example, a point where a contact accident or the like has occurred in the past) may be guided.

Furthermore, in the above-described embodiment, the trigger for displaying the peripheral delivery route is the distance between the current location and the delivery destination, but another trigger, for example, a user instruction may be used. Further, the configuration may be such that the display of the peripheral delivery route is terminated in response to the display termination instruction, and the guidance of the scheduled delivery route is switched to.

Each system that constitutes the above-described embodiment may be configured with a smaller number of devices that share functions.

Further, a configuration in which a part of the configuration of the above-described embodiment is omitted, or a configuration in which processing is changed or omitted can be assumed. For example, the acquisition of the parking status information may be omitted, and the parking position may be specified and guided without considering the parking status information.

The parking position information acquisition unit only needs to be able to acquire the parking position information regarding a plurality of parking positions that are candidates for the position where the vehicle that delivers the delivery to the delivery destination is parked. That is, there may be a plurality of positions where the vehicle is parked when delivering the delivery to the delivery destination. The parking position information is information indicating the plurality of parking positions for each delivery destination.

The delivery destination may be a place where the delivery is delivered (a destination associated with the delivery), and may be a facility such as a store or an office, or a private home. Of course, the delivery destination may belong to either a natural person or a corporation. The delivered items may be various items, may be parcels, sealed letters, other items, or atypical items. Various types of deliverables can be assumed, and even if they are classified by temperature such as chilled (low temperature (for example, 5°C or lower or around 0°C but not frozen), frozen, normal temperature, etc.) It may be good, it may be the classification of the product itself, such as cooked rice, fresh food, miscellaneous goods, magazines, or both.

The vehicle for delivering the delivery may be of various types, and may be a truck or the like, a passenger car, or a one-box car. The parking position may be a position where the vehicle is parked, and the parking position may be defined by various methods other than the configuration in which the parking position is indicated for each mesh as described above. For example, a parking lot or a position where the vehicle can be parked on the street may be indicated by coordinates or the like, or a parking frame in the parking lot may be defined as the parking position.

The delivery information acquisition unit only needs to be able to acquire delivery information regarding delivery. That is, the delivery information is defined so that the parking position can be specified based on the delivery information. Therefore, the delivery information may be any information that can be an element for specifying the parking position, and various information can be used as the delivery information. Further, the delivery information may be information related to the delivery (type of delivery, etc.), or information regarding the delivery time (specified delivery time zone designated as the time zone in which the delivery should be delivered or arrival of the vehicle). (Estimated time zone, estimated arrival time zone, etc.), or information regarding the delivery status of the delivery (progress with respect to schedule, road congestion status, etc.).

The parking position specifying unit only needs to be able to specify the parking position where the vehicle is parked when delivering the delivery, based on the parking position information and the delivery information. That is, the parking position specifying unit only needs to be able to specify the information regarding the delivery to the delivery destination based on the delivery information and the parking position where the vehicle should be parked in order to deliver the delivery.

The parking position where the vehicle should be parked may be specified by various factors, for example, the parking position recommended for delivering the delivery without breaking the rules, or the delivery may be efficient. It may be a parking position recommended for delivery to. The former includes, for example, a configuration that does not violate a rule such as a delivery permitted time zone, and the latter includes, for example, avoiding a parking position in use, and a moving distance/moving time of a vehicle or a delivery person. The composition etc. which make it short can be raised.

In addition, the parking position where the vehicle should be parked may be a parking position recommended for delivery without damaging or degrading the delivered product, or the delivered product can be delivered without complaining. It may be the recommended parking position for delivery. Examples of the former include a configuration that avoids uneven roads and reduces the possibility of being out of the control temperature range. Examples of the latter include a configuration that avoids the complaint occurrence point. Regardless of which form the parking position at which the vehicle is to be parked, it is sufficient that the parking position information or the delivery information describes information for identifying the parking position in various forms.

The parking position guide unit only needs to be able to guide the specified parking position. The mode for guiding the parking position may be various modes. That is, the configuration is not limited to the configuration in which the route to the parking position and the route from the parking position to the delivery destination are guided as in the above-described embodiment. For example, the parking position and the delivery destination position on the map are It may be configured to be guided.

The time zone such as parking time zone, designated delivery time zone, estimated arrival time zone, estimated arrival time zone, etc. is defined by abstract classification such as morning, daytime, night, and midnight. May be mixed with any one of the configurations specified by any numerical range, one of them may be used, or another definition may be used. When a part of the designated delivery time zone is included in the parking time zone, it may be determined by further analysis or the like whether the parking position can be parked. For example, the configuration may be such that it is considered that the vehicle can be parked at the parking position when most of the designated delivery time zones (ratio above the threshold) is included in the parking time zone.

The parking status information indicating whether or not the parking position is vacant may be various information other than the information specified based on the image captured by the camera. For example, it may be information (fullness information) indicating the usage status of the parking lot acquired from a sensor or the like installed in the parking lot. Of course, there may be a plurality of parking frames in the parking lot, and the information may indicate the usage status of each parking frame.

The complaint occurrence point may be a point at which a complaint that hinders delivery using a specific scheduled delivery route in the delivery process of the delivery item. Therefore, as described above, the presence or absence of complaints may be specified for each mesh, or the presence or absence of complaints may be specified for each narrower spot. There may be different types of complaints, such as complaints about noise when transporting deliverables, complaints about contact between delivery person and other person or accident related to delivery, parking position and parking method of vehicle. It may be a complaint or the like. When there are a plurality of types of complaints, the location of the complaint may be guided for each type.

Further, the method of identifying the parking position based on the parking position information and the delivery information as in the present invention can be applied as a program or a method. Further, the system, program, and method as described above may be realized as a single device or may be realized by using components shared with each unit provided in the vehicle, and include various modes. It is a waste. For example, it is possible to provide a method and program realized by the above system.
