Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for efficiently and timely allocating a vehicle in the business of transporting passengers, cargoes, etc. by vehicle according to the customer's request.

AVM system (automatic vehicle monit
The oring system) is an extremely effective system for operations such as allocating vehicles according to customer's orders, such as taxi operations, because the position and movement of the vehicle can be constantly grasped.

That is, after receiving a vehicle dispatch order from a customer,
This is because it is possible to immediately give an instruction to the vehicle that is determined to be the most appropriate for the vehicle allocation to the vehicle allocation order address. Note that the vehicle dispatch instruction is given by a telephone call by wireless communication.

However, since the conventional system is a centralized system that collectively manages vehicle dispatch orders and vehicle dynamics at the AVM system base station, the vehicle operator, that is, the crew member, does not know the vehicle dispatch order status at all. As a result, many vehicles were often left in areas where there were few orders for dispatch.

Therefore, when there are few vehicles (empty vehicles) that can be dispatched in the customer's vehicle dispatch order area, the customer is often kept waiting for a long time, and efficient vehicle dispatch operation cannot be performed.

[0006] Therefore, there is a demand for a system capable of responding to a customer's vehicle allocation order in a timely manner and enabling efficient vehicle allocation operation.

Example of accessing and numerically displaying the number of ordered items (see FIG. 6 (a)) That is, it is determined whether or not the data of the number of ordered vehicles is received in step S601, and if received, the data is sorted by area in step S602. Write the number of dispatch orders data to the memory.

After the writing in step S602, or when the order quantity data is not received in step S601, it is determined whether or not the user has entered a different area in step S60.
Judge with 3.

In this embodiment, when a taxi enters a different area, the area of the taxi is registered. That is, it is determined whether or not a taxi has entered a different area depending on whether or not area registration has been performed.

When entering a different area,
In step S604, the number of vehicle dispatch orders for the area is read from the memory and displayed (on the display device 9a). It should be noted that the display of the vehicle dispatch order quantity data may be limited to a predetermined time of, for example, about 30 seconds.

If it is determined in step S603 that the vehicle has not entered a different area, the display is erased in step S605.

As described above, the position of the own vehicle can be registered in the vehicle management center, and at the same time, the number of vehicle dispatch orders in the area can be known.

Example of accessing and alarming the number of orders (see FIG. 6 (b)) Steps S701 to S703 operate in the same manner as steps S601 to S603 of FIG. 6 (a).

That is, it is determined whether or not the vehicle dispatch order quantity data is received in step S701, and if received, the vehicle dispatch order quantity data for each area is written in the memory in step S702. After writing in step S702, or if the order quantity data has not been received in step S701, it is determined whether or not the customer has entered a different area in step S703.
To judge. Area registration is performed when entering a different area.

When entering a different area,
In step S704, the number of vehicle dispatch orders in the area is read from the memory, and it is determined in step S705 whether the number of vehicle dispatch orders is a predetermined value or more. If the number is more than the predetermined value, an alarm is activated in step S706.

[0115] If it is determined in step S703 that the vehicle has not entered a different area, or if it is determined in step S705 that the number of dispatch orders is less than or equal to a predetermined value, the procedure proceeds to the next step, and then the order is placed again in step S701. It is judged whether or not the number data has been received.

As described above, the position of the own vehicle can be registered in the vehicle management center, and at the same time, it is possible to know whether the number of vehicle dispatch orders in the area is large or small.

(3) Example-3 1) Configuration FIG. 7 is a block diagram for explaining the system configuration of Example-3, (a) is a block diagram for explaining the system configuration, and (b) is a block diagram.
Is the memory map. Note that (b) is a memory map of a storage area reserved for storing received data in the taxi data processing device.

The system configuration of the present embodiment is different from the system configuration of the embodiment-2 in that taxis 2a, 2b (2c, 2d, 2e, 2)
An instruction operation unit for appropriately reading the data stored in the memory of the data processing device 8c of f), that is, the data of the number of vehicle dispatch orders for each area according to the request of the crew.
It is a point equipped with 12.

Therefore, the data processing device 8c is provided with software for reading the memory according to the instruction (operation) of the instruction operating unit 12 and outputting it to the display device 9b.

Therefore, in the system of this embodiment, in addition to the area registration / dynamic management performed by the system as in the conventional system, the number of vehicle dispatch orders for each area managed by the vehicle dispatch order reception system 5b is transferred to a taxi. 2a, 2b (2
(c, 2d, 2e, 2f) is transmitted to the memory of the data processing device 8b, and the memory can be read to access the dispatch order number data.

2) Operation of the system The operation of the vehicle management center 1a (1b, 1c) is exactly the same as in Example-2. That is, the vehicle dispatch order quantity data is periodically transmitted.

Therefore, in this embodiment, the taxi 2
The operation of the data processing device 8c of a, 2b (2c, 2d, 2e, 2f) will be described.

Example of Accessing Number of Orders Only by Operation of Crew (See FIG. 8) FIG. 8 is a flowchart for explaining the operation of the taxi data processing device.

That is, it is determined whether or not the vehicle dispatch order quantity data is received in step S801, and if received, the area-specific vehicle dispatch order quantity data is written in the memory in step S802.

After the writing in step S802, or if the order quantity data is not received in step S801, it is determined in step S803 whether the number of the area to be confirmed has been input from the instruction operating unit 12.

If the confirmation area number is entered,
In step S804, the data in the memory address corresponding to the area number is read out and displayed (on the display device 9b).

If the confirmation area number has not been entered, the process proceeds to the next step, and then it is determined again in step S801 whether or not the order quantity data has been received. The taxi area registration will be performed as usual.

Example of automatically and manually accessing the number of orders (see FIG. 9) FIG. 9 is a flowchart for explaining the operation of the taxi data processing device.

This example is a system example in which the operation example of the embodiment-2 shown in FIG. 6 (a) and the operation example shown in FIG. 8 are combined.

That is, when a taxi enters a different area and area registration is performed, the number of dispatch orders in that area is automatically accessed. Further, by operating the instruction operating unit 12, the number of vehicle dispatch orders in each area can be appropriately accessed.

Specifically, it is determined in step S901 whether or not the vehicle dispatch order quantity data is received, and if it is received, the area-specific vehicle dispatch order quantity data is written in the memory in step S902.

After the writing in step S902, or if the order quantity data is not received in step S901, it is determined in step S803 whether or not the number of the area to be confirmed is input from the instruction operation unit 12.

If the confirmation area number is entered,
In step S904, the data in the memory address corresponding to the area number is read out, for example, for 5 seconds (on the display device 9b).
indicate.

If the confirmation area number is not entered in step S903 or if the display is terminated in step S904, the process proceeds to step S905, and it is determined whether or not the own vehicle, that is, the taxi has entered a different area. To do.

When entering a different area,
In step S906, the number of vehicle dispatch orders for the area is read from the memory and displayed (on the display device 9b). It should be noted that the display of the vehicle dispatch order quantity data is limited to a predetermined time of, for example, about 30 seconds.

If it is determined in step S905 that the vehicle has not entered a different area, the display is erased in step S907.

As described above, the position of the own vehicle can be registered in the vehicle management center, and at the same time, the number of vehicle dispatch orders in the area can be automatically and manually accessed.
Therefore, the taxi crew may operate the instruction operation unit 12 only when he / she wants to know the number of dispatch orders in other areas.

(4) Example 4 The daily and general dispatch request environment for taxis is based on statistical rationality. That is, it depends on the weather, day of the week, time of day, season, and so on. For example, there are many vehicle dispatch orders in the downtown area on weekends, and also when the weather is rainy. In addition, there are many orders for vehicle allocation during year-end parties and New Year parties.

[0139] These pieces of information are empirically known to the taxi crew. However, they are only inferred from limited empirical rules, not information based on statistical rationality.

By the way, in the first to third embodiments, the vehicle dispatch order receiving system 5b of the vehicle management center 1a (1b, 1c) is generally, as has been made clear in the conventional example,
The customers who have placed a vehicle dispatch order 6 _-1 , 6 _-2 , ... are categorized by area and the addresses and telephone numbers are stored as files.

Therefore, together with such information, the weather, month, day of the week, time of day, etc. when the dispatch order is accepted are made into a file and stored, and those data are aggregated and statistically analyzed to obtain them. It is possible to predict how the number of vehicle dispatch orders will change for each area from now on.

FIG. 10 is a diagram for explaining an example of statistical analysis data, which is data of a specific area. And (a) is the predicted value of the number of vehicle dispatch orders obtained from the past monthly aggregation results,
(b) is the forecast value of the number of vehicle dispatch orders obtained from the aggregation result by day of the week, and (c) is the forecast value of the vehicle dispatch order number obtained from the result of aggregation by time.

In other words, from FIG. 10 (a), the summer and year-end party
It can be seen that there are many dispatch orders during the New Year party season. Also, it can be seen that the number of dispatch orders will decrease slightly in the summer when the weather is rainy.

On the other hand, FIG. 10 (b) shows the forecasted number of vehicle dispatch orders for each day of December in FIG. 10 (a), showing that the number of vehicle dispatch orders increases on weekends when the weather is fine. There is.

Further, FIG. 10 (c) is a diagram showing the forecasted number of vehicle dispatch orders for each time on Friday in FIG. 10 (b), and shows that the number of vehicle dispatch orders increases from 18:00 in the evening to 2:00 in the middle of the night. ing. It can be seen that when the weather is raining, the number of dispatch orders tends to decrease after peaking at 20:00 in the evening. The figure
10 is just an example.

The purpose of this embodiment is to allow the taxi side to access data based on these statistical rationale. In other words, by doing so, the taxi crew can understand how the future dispatch order may change, and thus more timely dispatch can be performed.

As a concrete system configuration, the embodiment-
In the first to third embodiments, when transmitting and transmitting the vehicle allocation order number data from the vehicle management center, the vehicle allocation order predicted number data may be transmitted and transmitted together. The taxi side may display the received data.

[0148]

As described above, according to the vehicle dispatch system of the present invention, the crew member of the vehicle (taxi) can also grasp the number of vehicle dispatch orders for each area.

Therefore, it is possible to move to an area having a large number of vehicle dispatch orders by the voluntary judgment of the vehicle crew, and it is possible to construct a decentralized system.

As a result, the voluntary movement of vehicles to an area where many vehicle dispatch orders are requested is promoted, and as a result, it becomes possible to timely respond to the customer's vehicle dispatch orders. That is, the customer does not have to wait for a long time. In addition, efficient vehicle allocation operation becomes possible.

Further, if the crew members of the vehicle utilize the data that statistically predicts the area where the vehicle dispatch order increases, it is possible to voluntarily move the vehicle to the area before the vehicle dispatch order increases. The dispatch time can be extremely shortened.
