Hereinafter, embodiments of a maintenance management device, a maintenance management system, a maintenance management method, and a storage medium of the present invention will be described with reference to the drawings. In the following description, a maintenance target vehicle is, for example, a vehicle such as a two-wheeled vehicle, a three-wheeled vehicle, or a four-wheeled vehicle. A driving source of these vehicles is an internal combustion engine such as a diesel engine or a gasoline engine, an electric motor, or a combination thereof. The electric motor operates using electric power generated by a power generator connected to the internal combustion engine or power that is supplied when a secondary battery or a fuel cell is discharged. The vehicle may include a communication function (a communicator) for communicating with an external device and a human machine interface (HMI) for inputting/outputting information. The HMI includes, for example, a speaker, a display device, a buzzer, a touch panel, a switch, a key, and the like.
The maintenance management server 100 includes, for example, a communicator 110, an authenticator 120, an acquirer 130, a manager 140, a selector 150, an information provider 160, and a storage 180. The authenticator 120, the acquirer 130, the manager 140, the selector 150, and the information provider 160 are implemented, for example, by a hardware processor such as a central processing unit (CPU) executing a program (software). Some or all of the above components may be implemented by hardware (including a circuit; circuitry) such as a large-scale integration (LSI) circuit, an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a graphics processing unit (GPU) or may be implemented by software and hardware in cooperation. The program may be prestored in a storage device (a storage device including a non-transitory storage medium) such as an HDD or a flash memory or may be stored in a removable storage medium (the non-transitory storage medium) such as a DVD or a CD-ROM and installed in the storage device of the maintenance management server 100 when the storage medium is mounted in a drive device or the like. The maintenance management server 100 may function as a cloud server that communicates with the user terminal 200, the vehicle M, and the maintenance facility 300 (the facility terminal 310) via the network NW to transmit and receive various types of data or may function as a web server.
The storage 180 may be implemented by the above-described various storage devices, an EEPROM, a ROM, a RAM, or the like. The storage 180 stores, for example, user information 182, vehicle information 184, maintenance facility information 186, programs, and various other types of information. Details of the user information 182, the vehicle information 184, and the maintenance facility information 186 will be described below.
The communicator 110 communicates with the user terminal 200, the vehicle M, the maintenance facility 300 (the facility terminal 310), and other external devices via the network NW.
The authenticator 120 registers information about a user (for example, the user U1) who uses the maintenance management system 1. Specifically, the authenticator 120 receives information about the user U1 from the user terminal 200 and stores the received information in the user information 182 of the storage 180.
For example, when the user terminal 200 receives a user registration request, the authenticator 120 generates an image for inputting various types of information included in the user information 182, causes the terminal device that has received the request to display the image, and acquires user information input from the user terminal 200.
The authenticator 120 authenticates the user U1 who uses a service of the maintenance management system 1 on the basis of the registered user information 182. For example, the authenticator 120 authenticates the user U1 at a timing when a service usage request has been received from the user terminal 200. For example, when the usage request has been received, the authenticator 120 generates an authentication image for inputting authentication information such as a user ID and a password, causes the generated image to be displayed on the user terminal 200 from which the request has been received, and determines whether or not to permit the use of the service (the maintenance management system 1) according to whether or not authentication information matching the input authentication information is stored with reference to the authentication information of the user information 182 on the basis of the input authentication information input using the displayed image. For example, the authenticator 120 performs a process of permitting the use of the service when the authentication information matching the input authentication information is included in the user information 182 and denying the use of the service when the matching information is not included or causing new registration to be performed. The authenticator 120 may perform authentication similar to the above-described user authentication with respect to the maintenance facility 300.
The acquirer 130 acquires the vehicle information of the user U1 from the user terminal 200. The vehicle information includes, for example, owned vehicle information, a maintenance history, a mileage, vehicle verification information, and the like corresponding to the vehicle M. The maintenance history is a past maintenance history of the vehicle M (for example, a failure location or a replaced part, a maintenance period, repair content, costs, and the like). The maintenance history may include information about a maintenance facility where maintenance has been carried out, privilege information at that time, and the like. The mileage is a total mileage (a cumulated mileage) of the vehicle M. The vehicle verification information includes, for example, information such as a vehicle number, a type (a vehicle type), and a vehicle inspection expiration date. The acquirer 130 stores the acquired vehicle information in the vehicle information 184 and the like. The acquirer 130 may be acquired the vehicle information from the maintenance facility 300 where maintenance was carried out in the past as well as the user terminal 200.
The acquirer 130 acquires information about the maintenance facility from the maintenance facility 300 (the facility terminal 310) and stores the acquired information as maintenance facility information 186 in the storage 180. The maintenance facility information is an example of maintenance information for the vehicle M whose maintenance has been requested.
The manager 140 manages users who use the maintenance management system 1, manages vehicle information, manages maintenance facility information, and the like. The manager 140 manages the maintenance of the vehicle M. Details of the function of the manager 140 will be described below.
When the maintenance request for the vehicle M has been acquired, the selector 150 selects a maintenance facility 300 for requesting the maintenance corresponding to the maintenance request. Details of the function of the selector 150 will be described below.
The information provider 160 provides various types of information to the user terminal 200, the vehicle M, and the maintenance facility 300 (the facility terminal 310). The information provider 160 generates, for example, information such as images and sounds to be provided to the user terminal 200 or the vehicle M and the maintenance facility 300, and provides the generated information. For example, the information provider 160 provides the user terminal 200 and/or the vehicle M with information about a maintenance period associated with a vehicle inspection or the like and provides the user terminal 200 and/or the vehicle M with information about the maintenance facility 300. For example, the information provider 160 provides the maintenance facility 300 with information about the vehicle M whose maintenance has been requested and provides the maintenance facility 300 with information about the user U1.
Next, a configuration of the user terminal 200 will be described.
The terminal-side storage 290 may be implemented by the above-described various types of storage devices, an EEPROM, a ROM, a RAM, or the like. For example, the maintenance management application 292, the program, and various other types of information are stored in the terminal-side storage 290.
The terminal-side communicator 210 communicates with the maintenance management server 100, the maintenance facility 300, and other external devices using, for example, the network NW.
For example, the input 220 receives an input of the user U1 by operating various types of keys, buttons, and the like. The display 230 is, for example, a liquid crystal display (LCD), an organic electro luminescence (EL) display, or the like. The input 220 may be integrally configured with the display 230 as a touch panel. The display 230 displays various types of information according to the embodiment under the control of the output controller 280. The speaker 240 outputs a prescribed sound, for example, under the control of the output controller 280. For example, the microphone 250 receives a voice input of the user U1 under the control of the output controller 280.
The imager 260 is a digital camera that uses a solid-state image sensor (an image sensor) such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). For example, the imager 260 captures an image including a main body of the vehicle M of a maintenance target, a prescribed area in a vehicle cabin, a replacement target part, or the like according to an operation of the user U1.
The application executor 270 is implemented by executing a maintenance management application 292 stored in the terminal-side storage 290. The maintenance management application 292, for example, downloaded from an external device via the network NW, is installed in the user terminal 200. The maintenance management application 292 is an application program for controlling the output controller 280 such that an image provided from the maintenance management server 100 is output to the display 230 with respect to the user U1 and a sound corresponding to information provided from the maintenance management server 100 is output from the speaker 240. The application executor 270 transmits information input by the input 220 to the maintenance management server 100 and/or the facility terminal 310 via the terminal-side communicator 210.
The output controller 280 controls content and a display mode of the image to be displayed on the display 230 and content and an output mode of the sound to be output by the speaker 240 under the control of the application executor 270.
Next, a configuration of the facility terminal 310 of the maintenance facility 300 will be described.
The terminal-side storage 316 may be implemented by the above-described various types of storage devices, an EEPROM, a ROM, a RAM, or the like. For example, a program and various other types of information are stored in the terminal-side storage 316. The various types of information include, for example, maintenance facility information and information acquired from the maintenance management server 100, the user terminal 200, or the vehicle M.
The terminal-side communicator 311 communicates with the maintenance management server 100, the user terminal 200, the vehicle M, and other external devices using, for example, the network NW. The input 312 receives an input from an administrator of the maintenance facility 300, for example, by operating various types of keys, buttons, and the like. The output 313 includes, for example, a display, a speaker, and the like. The display is, for example, an LCD, an organic EL display, or the like. The input 312 may be integrally configured with the display as a touch panel. The display displays information acquired by the acquirer 314, information stored in the terminal-side storage 316, and the like. The speaker outputs, for example, a prescribed sound. The acquirer 314 acquires various types of information from the maintenance management server 100 and/or the user terminal 200. The acquired information may be output by the output 313 or may be stored in the terminal-side storage 316.
The information provider 315 provides information (for example, contact information, maintenance content, availability, work cost, and privilege information) corresponding to a request for acquiring maintenance facility information from the maintenance management server 100. The information provider 315 provides the vehicle M whose maintenance has been requested with information indicating that the target maintenance can be carried out, information about costs and privileges, and the like. In this case, the information provider 315 may provide the information corresponding to the maintenance request whose notification has been directly provided to the maintenance facility 300 and may access the maintenance management server 100 and provide information corresponding to the maintenance request published on the web. For example, the information provider 315 may generate information such as images and sounds to be provided to the maintenance management server 100, the user terminal 200, and the vehicle M, and provide the generated information.
Next, a series of processes related to the maintenance of the vehicle M of the embodiment will be described with reference to the drawings.
In the example of
The maintenance management application 292 of the user terminal 200 receives the maintenance guide image transmitted by the maintenance management server 100, and causes the display 230 to display the received image.
In the switch display area A13, for example, an icon IC11 for ending the display of the image IM10 is displayed. The icon IC11 is, for example, a graphical user interface (GUI) switch. The same is also true for the other icons to be described below. When a portion of “>>reservation” displayed on the screen by the user U1 has been selected (touched), the maintenance management application 292 transmits a display request for a reservation screen to the maintenance management server 100. The information provider 160 of the maintenance management server 100 generates an image (a maintenance reservation image) for making a maintenance reservation, provides the generated image to the user terminal 200, and causes the display 230 to display the generated image. When the icon IC11 has been selected, the maintenance management application 292 does not transition to the maintenance reservation image and ends the display of the image IM10.
In the switch display area A23, for example, an icon IC21 for transitioning to a screen for inputting information (for example, maintenance content) other than the information set in the desired date/time/place input area A22 and an icon IC22 for ending the display of an image IM20 are displayed. When the icon IC21 has been selected, the maintenance management application 292 transmits a display request for the next maintenance reservation image to the maintenance management server 100. The information provider 160 of the maintenance management server 100 generates the next maintenance reservation image, provides the generated next maintenance reservation image to the user terminal 200, and causes the display 230 to display the generated next maintenance reservation image. When the icon IC22 has been selected, the maintenance management application 292 cancels the reservation and ends the display of the image IM20.
In the switch display area A33, for example, an icon IC33 for returning to the maintenance reservation image IM20 shown in
Returning to
In the processes of (3-1) to (3-4) of
Next, the selector 150 selects a maintenance facility for requesting maintenance of the vehicle M from a plurality of maintenance facilities 300-1 to 300-4 on the basis of the reservation information and the maintenance facility information 186. In this case, the selector 150 selects a maintenance facility using, for example, a function based on artificial intelligence (AI). Specifically, the selector 150 selects a maintenance facility having highest availability among a plurality of maintenance facilities for which information indicating that maintenance of the vehicle M is possible is acquired (hereinafter simply referred to as a “plurality of maintenance facilities”). The selector 150 may extract a maintenance facility nearest a designated position P1 (a pick-up place or a drop-off place) from among the plurality of maintenance facilities. The selector 150 may select a maintenance facility whose maintenance cost (money amount) is lowest. On the basis of the privilege information, the selector 150 may select a maintenance facility having the most fulfilling services (for example, in which a car wash is included, the discount rate or the number of given privilege points is maximum, a free gift is most expensive, or the like). The selector 150 may select a maintenance facility having the highest evaluation of the evaluation information included in the maintenance facility information among the plurality of maintenance facilities. The selector 150 may select a maintenance facility having the lowest sales in a prescribed period (for example, monthly) among the plurality of maintenance facilities. The selector 150 may select the most frequently used maintenance facility among the maintenance facilities that previously carried out maintenance included in a maintenance history included in the vehicle information 184. The selector 150 may comprehensively determine selection results of the plurality of selection methods described above and finally select a maintenance facility.
The selector 150 may select a maintenance facility for requesting maintenance of the vehicle M using, for example, a bidding method. In this case, the selector 150 transmits information (maintenance facility information) about a maintenance facility (a maintenance facility satisfying the condition of the reservation information) where maintenance of the vehicle M is possible to the user terminal 200 and selects the maintenance facility selected by the user U1 as a maintenance facility for requesting maintenance of vehicle M. The selector 150 may select a maintenance facility that has input information indicating that the maintenance of the vehicle M can be carried out most rapidly with respect to the reservation information (the maintenance request) of the vehicle M published on the web as a highest-priority maintenance facility for requesting the maintenance of the vehicle M. The selector 150 may select a maintenance facility for requesting maintenance of the vehicle M on the basis of a priority level of the maintenance facility information set in advance by the user U1. For example, the selector 150 selects a maintenance facility having the lowest work cost when the user U1 prioritizes the work cost over other items and selects a maintenance facility having highest evaluation when the user U1 prioritizes the evaluation information over the other items.
In the example of
Next, the person in charge of the maintenance facility 300-4 moves to the designated place P1 to pick up the vehicle M on the date/time included in the reservation information ((5) of
Before or during the maintenance of the vehicle M in the above-described process of (6) of
In the switch display area A43, for example, an icon IC41 for accepting additional maintenance (replacement work) displayed in the additional maintenance information display area A42 and an icon IC42 for denying the additional maintenance are displayed. When the icon IC41 has been selected, the maintenance management application 292 transmits information indicating that the additional maintenance has been accepted to the maintenance facility 300-4 and the maintenance facility 300-4 carries out the maintenance of the vehicle M. When the icon IC42 has been selected, the maintenance management application 292 transmits information indicating that the additional maintenance has been denied to the maintenance facility 300-4. In this case, the additional maintenance of the vehicle M is not carried out. At the timing of the process of (6) of
The maintenance facility 300 and the user terminal 200 may communicate with each other via the maintenance management server 100. Thereby, the maintenance management server 100 can manage a state of the vehicle M or the maintenance facility 300 even after the maintenance facility 300 for maintaining the vehicle M is selected.
As described above, according to the present embodiment, the user U1 can request the maintenance of the vehicle M using a time period in which the vehicle M is not used at the excursion destination for a prescribed purpose. Although the maintenance guide image IM10 from the maintenance management server 100 is displayed on the user terminal 200 in the process of (1) of
Subsequently, when the reservation information has been acquired from the user terminal 200, the maintenance management server 100 transmits a request for acquiring the current (latest) maintenance facility information to one or more maintenance facilities 300 (step S104). The maintenance facility 300 transmits information such as currently feasible maintenance content, availability, and privilege information to the maintenance management server 100 (step S106). Next, the maintenance management server 100 selects a maintenance facility 300 for requesting maintenance included in the reservation information on the basis of the user terminal 200 and the maintenance facility information acquired from the maintenance facility 300 (step S108).
Subsequently, the maintenance management server 100 transmits information indicating that maintenance can be carried out included in the reservation information, information about the selected maintenance facility 300, and the like to the user terminal 200 (step S110). The maintenance management server 100 transmits information indicating that the maintenance facility for carrying out the maintenance has been selected, reservation information, vehicle information, and the like to the maintenance facility 300 for carrying out the maintenance of the vehicle M (step S112). Thereby, the user U1 can deliver the vehicle M to the person in charge of the maintenance facility 300 at the pick-up date/time and place included in the reservation information. Subsequently, the maintenance facility 300 carries out maintenance based on the reservation information (step S114).
Here, when it is determined that additional parts need to be replaced before or during maintenance, the maintenance facility 300 transmits inquiry (additional confirmation image) information about whether or not the parts need to be replaced to the user terminal 200 (step S116). Subsequently, the user terminal 200 displays the additional confirmation image transmitted from the maintenance facility 300 and transmits information about acceptance or denial from the user U1 to the maintenance facility 300 (step S118). Thereby, even if additional parts are replaced before or during maintenance, it is possible to confirm with the user U1 and carry out more appropriate maintenance. By confirming with the user U1 by presenting an image during the work, the correctness and reliability of the work can be improved. In the processing of steps S116 and S118, the transmission may be performed via the maintenance management server 100. Thereby, the maintenance management server 100 can manage a maintenance state in more detail.
Subsequently, after the maintenance is completed in the maintenance facility 300, the person in charge of the maintenance facility 300 moves the vehicle M after the maintenance to a designated position and delivers the vehicle M to the user U1. The user terminal 200 performs an electronic payment process for the maintenance cost (step S120). After the payment is completed, the maintenance facility 300 transmits information about a payment amount and/or final maintenance content (for example, a maintenance history) to the maintenance management server 100 (step S122).
The maintenance management server 100 stores information transmitted from the maintenance facility in the vehicle information 184, generates inquiry information about the evaluation of the maintenance facility 300 that has carried out maintenance (step S124), and transmits the generated inquiry information to the user terminal 200 (step S126). The user terminal 200 receives the inquiry information and transmits response information (an evaluation result) to the inquiry input by the user's operation to the maintenance management server 100 (step S128). The evaluation result may be, for example, a five-grade evaluation, an evaluation result in which “YES” or “NO” has been input to a plurality of questionnaires, or other index values indicating the goodness of the evaluation. The maintenance management server 100 updates the evaluation information of the maintenance facility information 186 on the basis of an input evaluation result.
In the process of
In the processing of step S102 of
According to a process of the so-called bidding method as shown in
According to the above-described embodiment, the maintenance management server 100 includes the acquirer 130 configured to acquire a maintenance request for the vehicle M; the manager 140 configured to manage information about maintenance facilities 300 where a maintenance process for the vehicle M is possible; and the selector 150 configured to select a maintenance facility 300 for which the maintenance process for the vehicle M is requested on the basis of information about a desired date of a user of the vehicle M, a place, and maintenance content included in the maintenance request acquired by the acquirer 130 and the information about the maintenance facilities 300. Thereby, it is possible to provide a more appropriate maintenance facility with respect to the maintenance request for the vehicle M. Therefore, the user can spend the waiting time meaningfully during the vehicle maintenance.
Specifically, according to the embodiment, the maintenance management server 100 manages the states of the vehicle M of the user U1 and the maintenance facility 300, such that the interaction (the burden and the trouble) between the user U1 associated with the maintenance of the vehicle M and the maintenance facility 300 can be reduced. According to the embodiment, on the day of the maintenance work day, the vehicle M may be picked up and dropped off at a designated place (including an excursion destination) and a designated time of the user. Thus, the user can finish other things to do at other times (time during maintenance) and can effectively utilize the time. According to the embodiment, when additional confirmation items or the like have occurred during maintenance, appropriate maintenance work can be carried out in a simple acceptance or denial procedure between the user terminal 200 and the maintenance facility 300.
By introducing a system as shown in the embodiment, for example, in consideration of the user's time constraint due to maintenance and the like, maintenance work can be carried out using the user's excursion destination to provide maintenance equipment that meets user needs and it is possible to develop business having an advantage over other services. Therefore, it is possible to limit the outflow of customers to other maintenance facilities and the like that are not registered in the system and it is possible to increase the sales of vehicle-related parts. On the maintenance facility side, even if there is a prior contract in the initial maintenance plan of the maintenance facility, other working hours can be adjusted in advance in accordance with the reservation information, such that the number of maintenance requests can be increased and sales can be increased.
The embodiment described above can be represented as follows.
