DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle dispatch system for performing an optimal dispatch in response to a call from a contractor.
The present invention relates to a vehicle dispatching system suitable for a sea dispatching system and the like.

[0002]

2. Description of the Related Art Conventionally, as a dispatching system in which a taxi company dispatches a vehicle in response to a call from a customer, a voice calling / answering system, an AVM (Automatic Vehicle Monitoring) system, and the like are known.

[0003] In the dispatching system based on the voice calling and answering method, when a dispatch center receives a telephone call for a dispatch request from a customer, the dispatch center calls all taxi cars to inform the taxi location of the customer by business radio, and the contents of the call are described. A taxi driver who is applicable, that is, is located near the calling position of the customer and corresponds to the condition of being currently vacant, etc., responds to the dispatch center with the on-board commercial radio and received the response. The dispatching center is a system that selects a taxi closest to the customer based on the contents of the response, and issues a dispatch instruction again to the selected taxi by business radio.

[0004] Further, in the dispatching system based on the AVM system, a receiver provided in each taxi receives a signal including position information of a sign pole provided along a road, so that a vehicle-mounted commercial radio can be used. Automatically operates and transmits the location information to the dispatch center. The dispatch center registers and manages the operation or standby position of each taxi for each dispatch area based on the location information, and calls the dispatch request from the customer. Upon receiving the notification, selection of a dispatched vehicle is determined based on the registration management contents. According to this AVM dispatch system, the dispatch center always knows the position of each taxi, so there is no need to search for the nearest taxi by business radio after receiving a contact from the customer, and promptly issue dispatch instructions. It is possible to do.

Further, in recent years, the position of each taxi has been accurately detected by using a GPS (Global Positioning System) system which is a global position measuring system, and dispatch is performed based on the detection result. Expectations are gathering for the dispatch system. According to the dispatch system using the GPS system, the exact position, speed, moving direction, and the like of each taxi can be instantaneously measured. Based on the measurement results, the dispatch center can accurately determine the taxi located closer to the customer. It becomes possible to select.

[0006]

However, in any of the above-described vehicle dispatching systems, when a customer who is out of the office makes a telephone call for a dispatch request from a public telephone or a mobile phone, the customer verbally calls. It is necessary to inform the dispatch center of the location and the dispatch request, and the dispatch center selects a taxi operating or waiting at a position close to the customer based on the calling position, and the customer receives the taxi for the taxi. The dispatch command including the calling position is issued through the business radio. Therefore, when the customer is not familiar with the geography of the destination, there is a problem that the call position cannot be accurately transmitted.

On the other hand, when a customer picks up a taxi in a downtown area, the customer can select a taxi owned by a specific company based on an indicator light provided on the roof of the taxi. If the person is visually impaired, there is a problem that it is very difficult to select a company by the indicator light.

The present invention has been made in view of such a situation, and an object of the present invention is to provide a vehicle dispatching system that can easily call a taxi or other vehicle of a specific company even from a place that is not familiar with geography.

The central processing unit 36 includes: (1) a process as self-position measuring means for taking in self-location information output from the GPS receiver 33 and displaying it on the display 38 together with map information taken from the database 34; 2) a process of fetching the vehicle identification information stored in the storage unit 37 and transmitting the information from the transceiver 32; (3) extracting the call location information of the customer based on the vehicle allocation request information fetched from the transceiver 32, (4) calculating the shortest route from the self-location information and the call location information and displaying the route on the map information; (5) also using the self-location information and the call location information Processing as an approach information transmitting means for detecting approach of a taxi to a calling position, generating an approach signal, and transmitting approach information from the transceiver 32; Receiving the signal output from the controller, generating a dispatch completion signal, and processing as a completion information transmitting means for transmitting the dispatch completion information from the transceiver 32; (7) receiving the dispatch completion information received from the transceiver 32, A process of terminating the display of the call position information and the route display on the display 38 is performed. Note that the approach information is transmitted from the transceiver 32 directly or via the relay base 8 to the portable calling device 21.

As shown in FIG. 4, the portable calling device 21 includes a transceiver 22 for transmitting and receiving to each of the beacon stations 5 by a weak radio signal, an operation unit 25 operated mainly by a customer when calling a vehicle, A central processing unit 26 that processes various information; a storage unit 27 that stores information; a light emitting element 28 that emits light in response to a command from the central processing unit 26;
Similarly, at least a speaker 29 that emits a voice in response to a command from the central processing unit 26 is provided.

The central processing unit 26 (1) receives the signal output from the operating unit 25, generates a dispatch request signal, and transmits the dispatch request signal from the transceiver 22. (2) The transceiver 22 transmits the dispatch request signal. In response to the captured approach information, the light-emitting element 28 and the speaker 29 emit light and sound to signal the approach of the vehicle, and perform processing as vehicle approach notification means.

Next, the vehicle dispatch system 1 of the first example will be described .
Will be described with reference to FIG.

In step S1, the management station 41 performs position measurement for grasping the current position of each taxi 3 irrespective of whether or not vehicle allocation request information has been received from the customer 2. Vehicle identification information individually assigned from each taxi 3 is constantly transmitted, and the beacon station 5 installed along the road receives the vehicle identification information, and the position identification information unique to the beacon station 5 and Each taxi 3 is transmitted to the management station 41 together with the regional group information.
The current operation or standby position of the vehicle is grasped. Information transmission between the beacon station 5 and the management station 41 is performed via a central processing station 6 which manages a network connected by an optical fiber network 7, and these are connected to an existing road traffic information communication system (Ve
hicle Information and Communication System).

The vehicle identification information received by the beacon station 5 from the taxi 3 preferably includes information indicating whether or not the taxi is currently vacant. It is also preferable that detailed information from the self-position measuring means, that is, information such as the current traveling position, traveling speed, and traveling direction is added. The determination whether the taxi is empty or not is made by the on-vehicle call notification device 31.
Can be automatically performed by connecting to the taxi meter, but may be determined by a manual operation of the driver.

In step S2, the management station 41 receives the dispatch request information from the customer 2 and specifies the calling position of the customer 2. The dispatch request information is transmitted as a wireless signal from the transceiver 22 of the portable calling device 21 and transmitted from the beacon station 5 that has received the signal to the management station 41 through the optical fiber network 7. The management station 41 specifies the calling position of the customer 2 from the location identification information unique to the beacon station 5 and the group information by region transmitted together with the dispatch request information.

Here, it is preferable that the radio signal transmitted by the portable calling device 21 is any of a radio wave signal, an optical communication signal, and an ultrasonic signal, but its transmission output has a legal limit. Depending on the calling position, transmission to the beacon station 5 may not be possible. Therefore, it is preferable to take measures for the customer transmitting the dispatch request information to be able to confirm that the information is reliably received by the beacon station. If the beacon station always transmits the in-range notification signal having the following, the mobile paging device that has received the signal can inform the customer that the user is in the communication area. Further, even if the beacon station that has received the dispatch request signal is provided with a return unit that returns a reception confirmation signal to the portable calling device, the customer can confirm the transmission of the dispatch request information.

In step S3, one or more specific taxis 3 operating or waiting near the calling position of the customer 2 are extracted at the management station 41 of the dispatch center 4 and dispatched to the specific taxi 3. A command is issued. The extraction procedure is the same as the regional group information received together with the dispatch request information in step S2 among the regional group information related to the vehicle identification information of each taxi already grasped and managed in step S1. This is done by extracting Here, if the number of applicable taxis reaches a large number, the taxis whose location identification information matches are further narrowed down. Here, when the position identification information matches,
This means the last taxi received by the beacon station that has received the dispatch request information, and taxis located in a very limited range are extracted. If there is no corresponding taxi, the taxi is searched sequentially from area group information close to the calling area until a taxi is extracted. Then, the management station 41 regards the position identification information received together with the dispatch request information as the call location information of the customer and adds the dispatch request information to the dispatch request information, and also applies the dispatch request information to the specific taxi extracted from the beacon station. To send a dispatch command.

In step S 4, the in-vehicle call notifying device 31, which has received the dispatch instruction from the transceiver 32, routes the call position of the customer on the map information of the display 38 based on the call position information added to the dispatch request information. Display with display. On the display 38, before receiving the dispatch command, the self-position sequentially measured by analyzing the data received by the GPS receiver 33 is displayed on the map information extracted from the database 34, The call location of the customer is displayed on the same map information together with the self location. The route is displayed by calculating the shortest route based on the calling position and the own position. If the customer is an elderly or handicapped person, information indicating that is added to the dispatch request information to identify or prioritize the calling position on the display 38 with respect to the calling position of another customer. Preferably, it is displayed.

In step S5, the central processing unit 36 senses that the distance between the calling position and the self-position has reached a predetermined distance, and the in-vehicle call notifying device 31 transmits the signal from the transceiver 32 to the customer's portable calling device. The approach information is transmitted to 21. It is convenient that the approach information is automatically transmitted, but it is also preferable that the driver is manually transmitted by the driver who has been notified of the approach from the central processing unit 36. In this manner, by transmitting the driver's intention to the transmission of the approach information, the taxi which has no intention to go to the customer 2 among the specific taxis 3 and merely passes close to the customer 2 can be used.
It is avoided that the approach information is automatically transmitted to the user. Then, the portable calling device 21 that has received the approach information by the transceiver 22 notifies the customer 2 of the approach of the taxi 3 by a light-emitting signal and a voice signal through the light-emitting element 28 and the speaker 29.

In step S6, the driver of the taxi 3 on which the customer 2 has boarded operates the vehicle-mounted call notification device 31.
The dispatching completion information for notifying the dispatching completion is transmitted from the server, and the dispatching completion information is transmitted to the management station 41 via the beacon station 5, and the management station 41 transmits the dispatching completion information to the specified taxi. Then, the in-vehicle call notifying device 31 that has received the dispatch completion information from the transceiver 32 automatically ends the display of the call position and the route of the customer 2 on the display 38. Here, the dispatch completion information is transmitted from each of the beacon stations 5 having the same regional group information that transmitted the dispatch request information to the specific taxi in the step S3, thereby transmitting the specific taxi. It is possible to transmit to at least a taxi running toward the customer. Further, since the communication of the vehicle allocation completion information and more reliable, it is also preferred example of transmitting to the particular taxi all vehicles through commercial radio from dispatch center 4 having received the information.

The vehicle dispatch system 1 of the first example described above .
In, the current position of each taxi 3 and the call position of the customer 2 are specified by the installation positions of the beacon stations that receive the vehicle identification information and the vehicle allocation request information transmitted from the taxi 3 and the customer 2. However, it is also a preferable example that, for example, a GPS receiver is built in the portable calling device and the detailed information on the calling position of the customer is transmitted to the management station via the beacon station. Such a system is particularly effective when calling a taxi from a densely populated area such as a downtown area. In addition, it is preferable that the portable calling device is provided with a telephone function as a normal portable telephone because the portable calling device is carried outside.

The in-vehicle call notifying device 31 has a display 38
The call position information displayed by the key need not be a position display on the map information, but may be a character display of a place name, an address and the like of the call position.

Next, FIG. 6 is an explanatory diagram showing a second example of the vehicle dispatch system which is the basis of the present invention.

The vehicle dispatching system 1 of the present embodiment is carried by a customer 2 and is provided at a dispatch center 4 and a portable calling device 21 for transmitting dispatch request information and calling position information using a wireless telephone communication system.

And a vehicle-mounted call notifying device 31 for communicating vehicle allocation request information transmitted from the customer 2 and the like. The main structural differences from the vehicle dispatch system 1 of the first example described above are as follows.

The vehicle dispatch system 1 of this embodiment is characterized by using a wireless telephone communication system as means for transmitting a dispatch request signal from the portable calling device 21. Therefore, the configuration and the operation mode of the vehicle-mounted call notification device 31 mounted on the taxi 3 can be substantially the same as the system of the above-described first example .

The radio telephone communication network 9 having the plurality of base stations 91,..., The beacon station 5, the central processing station 6, and the management station 4
1 and the optical fiber network 7 constitute a relay base 8 for exchanging information between the portable paging device 21 and the in-vehicle call notification device 31.

Based on the call location information received from the customer 2 through the wireless telephone communication network 9, the management station 41 provides a taxi 3 having regional group information indicating the area of the call location or the nearest area. .. Are transmitted to the beacon station 3 to which the regional group information is allocated through the optical fiber network 7, and the extracted taxi 3,
A dispatch command is issued to.

Here, as the wireless telephone communication network 9, a terrestrial cellular or personal communication telephone network, a satellite telephone communication network, or the like can be used.

As shown in FIG. 7, the portable calling device 21 includes a wireless telephone 22a for transmitting dispatch request information and calling position information via the wireless telephone communication network 9, and

The central processing unit 26 (1) receives the signal output from the operation unit 25, generates a dispatch request signal, analyzes the data output from the GPS receiver 23, and Processing as position identification means for transmitting the call location information to the dispatch request signal and transmitting from the wireless telephone 22a; (2) receiving the approach information taken from the receiver 22b, At 29, processing as vehicle approach notification means for signaling the approach of the taxi 3 by light emission and voice is performed.

The processing procedure in the vehicle dispatch system 1 of the second example described above is the same as the processing procedure described in FIG. 5 in the first example except for steps S2 and S3.

In step S2 of this example , the management station 41 receives dispatch request information and call location information from the customer 2 through the wireless telephone communication network 9 including a plurality of base stations 91,. In this example, the calling position is specified in detail by the GPS receiver 23 in the portable calling device 21 that transmits the dispatch request information, and the management station 41 transmits the dispatch request signal to which the calling position information is added. Receive.

In step S3, the dispatch center 4
In the management station 41, one or more specific taxis 3 operating or waiting at a position close to the calling position of the customer 2 are extracted, and a dispatch instruction is issued to the specific taxi 3. The extraction procedure is performed by extracting regional group information indicating the region to which the calling position received in step S2 belongs, from regional group information relating to the vehicle identification information of each taxi 3 grasped in step S1. Done. Here, when the number of applicable taxis 3 is large, the number of taxis 3 is narrowed down by extracting position identification information indicating a position close to the calling position from the position identification information related to the vehicle identification information of each taxi 3. If there is no corresponding taxi 3, the taxi 3 is searched sequentially from the regional group information indicating the area close to the area to which the calling position belongs until the taxi 3 is extracted. And the management station 41
Transmits a dispatch request information to which the call position information is added to the extracted taxi 3 from the beacon station 5 to issue a dispatch instruction.

According to the vehicle dispatch system 1 of the second example described above, since the wireless telephone communication system is used as a communication means between the portable calling device 21 and the management station 41, the beacon is located near the calling position. Even when the station 5 is not present, the dispatch request information can be reliably transmitted, and the portable calling device 21 itself is provided with detailed calling position specifying means by the GPS receiver 23. The taxi 3 can reliably find the customer 2 even in a place where people are crowded, such as a downtown area. As described above, it is preferable that the mobile calling device using the wireless telephone communication system as a communication means with the dispatch center is provided with a normal mobile phone function.

Next, FIG. 8 is a block diagram showing a third example of the vehicle dispatch system which is the basis of the present invention.

The vehicle dispatch system 1 of this example is carried by the customer 2 and is provided at the dispatch center 4 with a portable calling device 21 for transmitting dispatch request information and calling position information using a radio telephone communication system.

The portable calling device 21 is connected to the
Almost the same as the second example can be adopted, but the approach information transmitted from the on-board call notification device 31 of the taxi 3 is shown in FIG. 7 via the base station 91 or the management station 41 of the wireless telephone communication system. Since it is received by the wireless telephone 22b,
The receiver 22b is unnecessary in the configuration.

Next, the vehicle dispatch system 1 of the third example described above .
Will be described with reference to FIG.

In step S 1, position measurement is performed for the management station 41 to grasp the current position of each taxi 3 irrespective of the reception of dispatch request information from the customer 2. In each taxi 3, the self-position is constantly measured by the GPS receiver, and the self-position information and the vehicle identification information are continuously or at predetermined time intervals from the radio telephone 32a to the radio telephone communication comprising a plurality of base stations 91,. Management station 4 through network 9
By transmitting the information to 1, the current operation or standby position of each taxi is grasped.

In step S2, the management station 41 sends the customer 2 through the wireless telephone communication network 9 comprising a plurality of base stations 91,.
And call location information from the vehicle. Here, the management station 41 receives the dispatch request information,
It is preferable to request each taxi 3 to transmit the self-location information.

In step S3, the management station 41 of the dispatch center 4 extracts one or more specific taxis 3 operating or waiting at a position close to the calling position of the customer 2, and for the specific taxi 3, The vehicle allocation request is transmitted by transmitting vehicle allocation request information to which call location information is added through the wireless telephone communication network 9. The extraction procedure is not particularly limited, but the following extraction method is convenient. That is, when the base station 91 receives the vehicle identification information or the vehicle allocation request information, identification information unique to the base station 91 is added to the received information. Then, the management station 41 manages the vehicle identification information together with the identification information,
When receiving the dispatch request signal, the taxi issuing the dispatch instruction is specified by extracting the vehicle identification information to which the same identification information as the identification information attached to the information is attached.

In step S 4, the in-vehicle call notifying device 31, which has received the dispatch instruction by the wireless telephone 32 a, displays the call position on the map information of the display 38 according to the call position information added to the dispatch request information. I do. The display 38 displays the taxi's own position on the map information before receiving the dispatch instruction, and the call position can be displayed on the same map information together with the self position. Then, the route display is performed by calculating the shortest route from the calling position and the own position.

In step S5, the central processing unit 36, having sensed that the distance between the calling position and the self-position has reached a predetermined distance, sends the base station 91 from the wireless telephone 32a.
Only, or automatically transmits the approach information to the customer via the management station 41. Then, the portable calling device 21 that has received the approach information by the wireless telephone 22a notifies the customer 2 of the approach of the taxi 3 to the customer 2 by the light emitting element 28 and the speaker 29 by the light emitting signal and the voice signal.

In step S6, the driver of the taxi 3 on which the customer 2 has boarded operates the vehicle-mounted call notification device 31.
Is transmitted to the management station 41 via the wireless telephone communication network 91, and the management station 41 transmits the allocation completion information to all the specified taxis via the wireless telephone communication network 9 as well. . And the wireless telephone 32

The display of the call position and the route of the customer 2 on the display 38 are automatically terminated.

In this example , the dispatching command issued by the management station 41 can be individually issued for each taxi through the wireless telephone communication network 9, so that only one specific taxi is extracted and dispatched only to the taxi. By issuing the command, it is possible to allocate a taxi more efficiently. In this case, the dispatch completion information merely serves to report to the management station that the specific taxi that the customer has boarded has been dispatched, and the management station 41 sends the dispatch completion information to another taxi. No need.

In the vehicle dispatch system 1 of the second example described above, a communication system using a beacon station 5 and a communication system using a wireless telephone communication network 9 are used as a relay base 8 for relaying information. Although an example is shown, the mode in which both communication systems are used in combination is not limited to this. For example, when the management station 41 transmits the dispatch request information and the call position information to the specified taxi 3, or when the vehicle-mounted call notification is issued. The selection and combination of communication systems, such as a system that uses the wireless telephone communication network 9 only when the device 31 transmits the dispatching completion information to the management station 41, is appropriately determined according to the situation in which the vehicle dispatching system is used. Is preferred.

[0074] Further, as the communication means between the cab and the dispatch center, it is also preferred example of the use of radio for business provided taxi and dispatch centers. As described above, as a dispatch system for exchanging information between a taxi and a dispatch center by radio waves, for example,
As shown in FIG. 10, the vehicle location information and the vehicle identification information are transmitted from the on-board call notification device 31 mounted on each taxi 3 to the timely vehicle allocation center 4 through the business-use radio 39, and the vehicle allocation to which the call position information is added. The dispatch center 4 that has received the request information from the mobile calling device 21 of the customer 2 through a communication system using a beacon station or a wireless telephone communication system, based on the calling position information of the customer, calls the taxi 3 located near the customer. One or more vehicles are extracted, and dispatch request information to which the call location information is added is transmitted from the business-use radio 42 in the dispatch center 4 to the extracted taxi 3, and the on-vehicle call of the taxi 3 receiving the information is transmitted. It is preferable that the notification device 31 displays the own vehicle position, the calling position, and the shortest route on the map information on the display.

The first example which is the basis of the present invention shown above,
Although the vehicle dispatch system 1 of the second example and the third example both transmit and receive various types of information via the management station 41, the information is transmitted and received only via the base station 91.
It may be. The embodiment of the present invention applies to each of these examples.
Excluding the relay base 8 such as the management station 41 and the base station 91,
Directly between the mobile paging device 21 and the in-vehicle call notification device 31

The position specifying means provided in the portable calling device includes a device for specifying a calling position of a subscriber by receiving and analyzing radio signals from a plurality of GPS satellites, and a device for assigning position identification information to a road surface. If the call location of the contractor is specified from the position identification information by receiving the position identification information from the beacon station arranged along, if the contractor transmits the dispatch request information, the place name of the call position or the like. Since the calling position is automatically added to the dispatch request information without inputting the address or the like, the contractor can call the vehicle without knowing the place name of the calling position.

If the dispatch request information transmitted by the portable calling device is a weak radio signal that can be transmitted only within a range of a radius of 100 m, the vehicle receiving the dispatch request information has a region within a radius of 100 m around the calling position. And vehicles can be efficiently dispatched even in an area where vehicles are densely located, such as a downtown area.

The in-vehicle call notifying device includes a self-position measuring means for specifying a self-position and a display means for displaying the self-position on the map information. If the vehicle dispatching system displays the calling position of the contractor added to the request information together with the self-position on the map information, the vehicle driver can confirm the calling position and the self-position of the contractor on the map. The route to the calling position and the approximate required time can always be grasped, and even when the geographical knowledge around the calling position is poor, it is possible to reliably reach the subscriber.

If the personal identification information of the contractor is added to the dispatch request information, the contractor using the system can be managed, and the most suitable vehicle can be dispatched according to each contractor. For example, when the contractor making a vehicle call is a disabled person, a special vehicle that can be easily boarded by the disabled person can be allocated.

The on-vehicle call notifying device includes an approach information transmitting means for transmitting approach information when a vehicle approaches the call position of the contractor, and the portable calling device receives the approach information and emits sound and light. By providing vehicle approach notification means for signaling to the contractor the approach of the vehicle by any of or a combination of vibrations, the contractor can pay attention at the same time as the vehicle approaches, and until the signal is given In the meantime, it is possible to stand by at a free place within a range in which the approach information can be received, and to prevent the vehicle from being overlooked without noticing that the vehicle is approaching. It is possible to reliably notify the inconvenienced contractor of the approach of the vehicle.

The portable paging device or the in-vehicle call notifying device includes completion information transmitting means for transmitting the dispatching complete information. The in-vehicle call notifying device receives the dispatching complete information and terminates the display of the call position of the contractor. In addition, it is possible to notify other vehicles heading to the calling position of the completion of the dispatch.
