  Here, the operation data collected and accumulated in the management center 1 will be described. FIG. 2 illustrates the configuration of operation data. As shown in this figure, the operation data includes a plurality of operation records, and each operation record (corresponding to each row other than the top row in FIG. 2) is one of a plurality of delivery vehicles in the past. This is data relating to the operation (that is, movement) from the departure place to the destination. In the operation data, a plurality of operation records corresponding to a plurality of operations are recorded for the same delivery vehicle 2. As described above, the operation data includes a plurality of operation records for a plurality of different delivery vehicles 2.

  The operation record relating to a certain operation of the delivery vehicle 2 includes the vehicle ID of the delivery vehicle 2, the load type and the load amount of the delivery vehicle 2 at the time of the operation, the departure and destination of the operation, the departure time of the operation, It includes the time required for the operation and the total fuel consumption during the operation. An individual operation record related to a certain operation of a certain delivery vehicle 2 is further applied to a change in the internal temperature of the delivery vehicle 2 at the time of the operation (for example, a temperature change every minute) and a body of the delivery vehicle 2. Including changes in horizontal G. Furthermore, the route from the departure point of the operation to the destination (for example, the position of the delivery vehicle 2 every second) is also included.

  Of these multiple types of quantities included in each operation record, each of the required time, total fuel consumption, lateral G transition, and internal temperature transition is an example of operational results.

  The operation in which such operation data is sequentially collected and accumulated in the management center 1 as each delivery vehicle 2 is operated is well known.

  For example, when carrying out a certain operation, when the load 30 is first loaded into the luggage compartment 2a at the departure place, the passenger of each delivery vehicle 2 uses the reader 22 to read from the load information storage medium attached to each load 30. The load information (including the load type) is read. Here, the cargo information storage medium is, for example, a two-dimensional code such as a barcode or a QR code (registered trademark), an IC tag, or an RFID tag. Then, the reader 22 outputs the read cargo information to the in-vehicle device 27, and the in-vehicle device 27 records the cargo information based on this information. In this example, it is assumed that only loads of the same load type are loaded into the same operation of the same delivery vehicle 2.

  Further, after all the loads are loaded, the output value of the in-chamber weight sensor of the sensor group 24, that is, the load amount is calculated based on the fact that the occupant performs a predetermined operation on the operation unit 20. 27 records. Further, based on the fact that the occupant inputs the departure place and the destination to the operation unit 20, the in-vehicle device 27 records the departure place and the destination. Further, when the vehicle speed sensor of the sensor group 24 detects the start of movement of the delivery vehicle 2, the in-vehicle device 27 records the date and time at that time as the departure date and time until the delivery vehicle 2 arrives at the destination. Periodically, the internal temperature, the lateral G, the fuel remaining amount, and the position of the delivery vehicle 2 at that time point are respectively measured using the internal temperature sensor, lateral G sensor, fuel remaining amount sensor, and GPS receiver 23. Identify and record.

  Then, when the delivery vehicle 2 arrives at the destination, the time from the departure date and time to the current date is recorded as the required time, and the total amount of decrease of the fuel remaining amount sensor (excluding the increase amount when increased) is calculated as the total fuel. Record as consumption. Moreover, the transition of the position of the delivery vehicle 2 is recorded as a route. Also, the vehicle ID of the own vehicle (registered in advance) is recorded.

  In this way, the in-vehicle device 27 creates and records one operation record each time it operates. The operation record thus recorded is recorded in a USB memory or the like, and carried, for example, to a computer installed in the office described above, and transmitted from the computer to the management center 1. Alternatively, the in-vehicle device 27 may be configured to transmit the recorded operation record to the management center 1 using the communication device 21.

  In the management center 1, the control unit 13 receives this operation record via the communication unit 11, and uses the received operation record (including information such as each row in FIG. 2) as operation data in the storage unit 12. Record additional.

  Next, the route determination operation in this operation management system will be described. FIG. 3 shows a flowchart of processing executed by the vehicle-mounted device 27 for this operation, and FIG. 4 shows a flowchart of processing executed by the control unit 13 of the management center 1.

  First, an occupant of a certain delivery vehicle 2 starts operation toward the destination from now on, in order to determine the route from the departure place (that is, the current location) to the destination, Perform a predetermined operation. Based on this operation being performed, the in-vehicle device 27 starts executing the processing of FIG.

  In the process of FIG. 3, first, at step 105, the departure time (ie, current time) is specified, and then at step 110, the departure place (ie, current location) is specified based on the output of the current GPS receiver 23. I do. Subsequently, in step 115, the destination is specified in accordance with the destination input operation to the operation unit 20 by the occupant.

  Subsequently, in step 120, it is determined whether or not a route is acquired from the management center 1 in accordance with a selection operation performed on the operation unit 20 by a passenger.

  When the occupant wants to determine the destination by a normal search method using only the function of the in-vehicle device 27, the occupant performs an operation not to acquire a route from the management center 1, and in this case, the in-vehicle device 27 performs step 120. To step 125. In step 125, a normal route search is performed. That is, the optimal route from the departure place to the destination is calculated using a well-known search method such as the Dijkstra method using the map data in the map data storage medium without communicating with the management center 1. At this time, the occupant can select any one of well-known options “highway priority”, “general road priority”, and “distance priority” as an option of the search method. And the vehicle equipment 27 determines the calculated optimal route as a guidance route.

  After step 120, the processing in FIG. 3 is completed, and the vehicle-mounted device 27 uses the output of the GPS receiver 23 and the map data to guide the route in a known manner so that the vehicle travels along the determined guide route. I do.

  When the occupant wants to determine the destination using the function of the management center 1, the occupant performs an operation for obtaining a route from the management center 1, and in that case, the vehicle-mounted device 27 moves from step 120 to step 130. move on.

  In step 130, the current product load amount is specified. For example, when an occupant inputs a product load amount to the operation unit 20, the input product load amount may be specified as the current product load amount. Alternatively, the product load amount may be specified based on the current output content of the in-compartment weight sensor.

  In step 135, the current cargo type is specified. The types of cargo in this embodiment include “art”, “precision machinery”, “room temperature fresh food”, “frozen food”, and “others”. The “room temperature fresh food” is a food product stored at room temperature.

  As a method for specifying the load type, for example, when the occupant inputs the load type to the operation unit 20, the input load type may be specified as the current load type. Alternatively, when the occupant causes the reader 22 to read the load information storage medium attached to any one of the loads 30 of the vehicle, the load information read by the reader 22 is used as the current load type. May be specified.

Subsequently, in Step 140, a route request is transmitted to the management center 1 using the communication device 21. The route request includes the departure time specified in step 105, the departure point specified in step 110, the destination specified in step 115, the product load amount specified in step 130,
And the cargo type specified in step 135 is included. Subsequently, in step 140, it waits until it receives route information as a response to this route request.

  On the other hand, in the management center 1, the control unit 13 stands by until a route request is received in step 210 in the processing of FIG. When the route request transmitted from the in-vehicle device 27 is received via the communication unit 11 as described above, the process proceeds to step 220, and all operation records that conform to the content of the received route request (the one that conforms to 1 1 is extracted from the operation data.

Specifically, the operation records to be extracted are all the operation records that satisfy the following conditions (a) to (e).
Condition (a): having a departure time that is the same as or similar to the departure time in the route request.
Condition (b): having the same or similar starting point as the starting point in the route request.
Condition (c): having the same or similar destination as the destination in the route request.
Condition (d): It has the same or similar product load amount as that in the route request.
Condition (e): having the same load type as the load type in the route request.

  Here, “similar” in the condition (a) corresponds to “similar” if at least “hour” is the same among the time consisting of “hour”, “minute”, and “second”. To do. Also, “similar” in the conditions (b) and (c) corresponds to “similar” if the distance between the two is within a predetermined distance (for example, 50 meters). Further, “similar” in the condition (d) corresponds to “similar” if, for example, the weight difference between the two is within a predetermined amount (for example, 100 kg).

  The operation record extracted in this way is an operation record when the vehicle has already traveled under substantially the same operation conditions as the vehicle 2 that has transmitted the route request. Subsequently, in step 230, route information including all of the extracted operation records is transmitted to the in-vehicle device 27 that is the transmission source of the route request using the communication unit 11. After step 230, the process returns to step 210 and waits for reception of a route request again.

  On the other hand, when the in-vehicle device 27 receives the route information transmitted as described above via the communication device 21, the in-vehicle device 27 proceeds from step 145 to step 150, and displays and receives selection of the received route information.

  Specifically, an image as illustrated in FIG. 5 is displayed on the display screen of the display device 25. The image in FIG. 5 includes a determination button 51 and another route button 52 as buttons that can be selected by the passenger using the operation unit 20.

  The image in FIG. 5 includes a list display 53 based on the received route information. The list display 53 displays information based on the operation record for each operation record with respect to the operation record (there may be one or plural cases) in the received route information.

  Specifically, in the list display 53, one line corresponds to one operation record, and each line displays information based on the corresponding operation record. When information based on all the operation records cannot be displayed on the display screen at a time, the occupant can scroll using the operation unit 20.

  In addition, the display order (display order of each line) of the information based on each operation record in the list display 53 can be changed according to the operation of the occupant. For example, when the occupant performs an operation with priority on the total fuel consumption using the operation unit 20, the in-vehicle device 27 changes the display order so that the total fuel consumption is displayed in ascending order. Further, for example, when the occupant performs an operation with priority on arrival date and time using the operation unit 20, the in-vehicle device 27 changes the display order so that the arrival date and time are displayed in order from the earliest. Further, for example, when the occupant performs an operation with priority on the maximum lateral G using the operation unit 20, the in-vehicle device 27 changes the display order so that the maximum lateral G is displayed in descending order. Further, for example, when the occupant performs an operation with priority on the internal temperature range using the operation unit 20, the in-vehicle device 27 changes the display order so that the internal temperature range is displayed in ascending order.

  In the list display 53, the row corresponding to a certain operation route includes the total fuel consumption included in the operation record, and also includes the arrival date and time, the maximum horizontal G, and the internal temperature range. The arrival date / time is a time obtained by adding the required time included in the operation record to the departure date / time included in the operation record. The maximum horizontal G is the maximum horizontal G among the transitions of the horizontal G included in the operation record. The internal temperature range is a difference between the maximum value and the minimum value of the internal temperature included in the operation record.

  In addition, the occupant can select any one line in the list display 53 by using the operation unit 20, and the vehicle-mounted device 27 uses the map data included in the map data storage medium to map 54, the route 55 included in the operation record corresponding to the row selected by the occupant's operation is displayed.

  The occupant selects one route that is considered optimal based on the displayed total fuel consumption, arrival time, maximum lateral G, internal temperature range, and route. Then, an operation of selecting a line corresponding to the selected route is performed on the operation unit 20, and then an operation of pressing the enter button 51 is performed on the operation unit 20.

  In this way, the occupant is optimal for the host vehicle while evaluating a plurality of types of data obtained based on operation results such as total fuel consumption, arrival time, maximum lateral G, and temperature range in the warehouse, from multiple perspectives. A route can be selected. For example, when it is desired to give the highest priority to cost, the arrival time may be selected with the highest priority placed on earlyness. Further, for example, when it is desired to give the highest priority to the safety of the load, the selection may be made with the greatest importance on the smallness of the maximum lateral G. In addition, for example, when it is desired to give the highest priority to the temperature stability of the cargo, the selection may be made with the highest priority on the narrowness of the internal temperature range.

  When an operation of pressing the determination button 51 is performed, the vehicle-mounted device 27 proceeds to step 155 and determines a guidance route. Specifically, the route in the operation record corresponding to the selected line is determined as the guide route from the current location to the destination. After step 155, the processing in FIG. 3 is completed, and the vehicle-mounted device 27 uses the output of the GPS receiver 23 and the map data to guide the route in a known manner so that the vehicle travels along the determined guide route. I do.

  If the occupant determines that any route displayed in the list display 53 is not appropriate, the occupant can perform an operation for selecting the other route button 52 on the operation unit 20 without selecting the determination button 51. When the operation of selecting the other route button 52 is performed, the vehicle-mounted device 27 proceeds from step 150 to step 125, and as described above, performs a normal route search and determines a guide route. After step 120, the processing in FIG. 3 is completed, and the vehicle-mounted device 27 uses the output of the GPS receiver 23 and the map data to guide the route in a known manner so that the vehicle travels along the determined guide route. I do.

  As described above, the in-vehicle device 27 transmits a route request including the departure time, the departure place, the destination, the loaded load amount, and the loaded type of the delivery vehicle 2 as a loading destination to the management center 1. Then, the management center 1 extracts a plurality of operation records that match the departure time, departure place, destination, load amount, and load type in the received route request from the operation data. Send to. The in-vehicle device displays, for each received operation record, the total fuel consumption, the arrival date and time, the maximum horizontal G internal temperature range as the amount based on the operation record, and the route included in the operation record selected by the occupant Is a guide route.

  In this way, the route can be selected from the operation records corresponding to the operation that matches the departure point, the destination, and the load type using the plurality of operation records accumulated in the management center. The optimal route can be determined according to the load.

  For example, in the above embodiment, each operation record in the operation data includes information on the required time, but the arrival date and time may be specified instead of the required time. That is, each operation record only needs to include an amount (for example, required time, for example, departure date and arrival date and time) that can specify the required time.

  Moreover, in the said embodiment, each of the required time, total fuel consumption, the transition of the horizontal G, and the transition of the inside temperature is included as an example of the operation results included in each operation record. Other amounts may be used.

  Moreover, in the said embodiment, although the total fuel consumption is described as an example of the total consumption of the drive energy source of the delivery vehicle 2, the total consumption of the drive energy source of the delivery vehicle 2 is electric power of an electric vehicle. It may be the total energy consumption (unit: kWh, for example).

  Moreover, you may replace the transition of the horizontal G at the time of operation recorded on each operation record with the maximum value of the horizontal G at the time of operation.

  In the above embodiment, the route request transmitted from the in-vehicle device 27 includes the departure time, the departure place, the destination, the amount of load, and the load type, but all of these are not necessarily included. Not necessary. For example, only the departure point, the destination, and the load type may be included. In this case, the management center extracts a plurality of operation records from the operation data having the departure point, the destination, and the load type that are similar or coincident with the start point and the destination in the received route request and match the load type. .
