Each function of the maintenance necessity estimation unit 16, the vehicle allocation vehicle determination unit 17, and the movement instruction unit 18 is realized by the software installed in the server 1.

The usage request acquisition unit 11 receives the usage request information of the vehicle 2 from the user transmitted from the user terminal device 3, and outputs the usage request information to the database 12. This usage request information includes the user's ID, the user's intention to dispatch a vehicle, the user's current position, the user's desired boarding point and disembarking point (position information such as latitude and longitude), the user's desired vehicle allocation time, and the number of passengers. In addition, it may include user's individual attribute information such as the user's age, occupation, family structure, and preference, the user's usage history of the vehicle allocation service, weather and other environmental information at the time of vehicle allocation, and environment information of the vehicle allocation route. In addition to acquiring the usage request information transmitted from the user terminal device 3, the usage request acquisition unit 11 may store a part of the usage request information of the user in the database 12 in advance. May acquire a part of the usage request information from the database 12 based on the user's ID.

The database 12 includes user attribute data including user individual attribute information such as the user's age, occupation, family structure, and preference associated with the user's ID, which is output from the usage request acquisition unit 11, and the user's vehicle dispatch service. User history data including the usage history of the user, boarding / alighting place data including the user's boarding / alighting place information, environment data at the time of vehicle allocation including the weather at the time of vehicle allocation and environmental information of the vehicle allocation route, and vehicle allocation time data including the vehicle allocation time. Store temporarily or permanently.

In addition to the information related to the usage request output from the usage request acquisition unit 11, the database 12 stores vehicle information transmitted from the vehicle 2 and map data. For example, in addition to the vehicle type, the registration date of the vehicle, and other static information known in advance, dynamic vehicle information transmitted from the vehicle state detection unit 22 of the vehicle 2 at predetermined time intervals is stored. In the vehicle dispatch service of this example, since there are a plurality of vehicles 2, all vehicle information existing in the predetermined service area is stored here. The vehicle information includes the position information of the vehicle 2, the direction of the vehicle, the vehicle speed, the open / closed state of the door lock and the door, the seat belt sensor value, various vehicle states such as whether or not the vehicle is automatically driven, the period of use of the vehicle 2, and the use of the vehicle 2. Number of times, vehicle 2 riding distance, vehicle 2 running energy remaining (fuel remaining in engine car, battery remaining in electric vehicle, fuel remaining and / or battery remaining in hybrid vehicle), Life of various parts of vehicle 2, software update information of computer (ECU) mounted on vehicle 2, cumulative number of passengers of vehicle 2 for each maintenance, travel area of vehicle 2, weather when using vehicle 2 include. In addition, information on remote monitoring of unmanned autonomous driving, such as whether vehicle requests can be received, whether cleaning or other maintenance is in progress, whether there are passengers and the number of passengers, and whether the vehicle has arrived at the destination of the transportation instruction, is also the same vehicle. It is stored in association with the ID of.

The map data stored in the database 12 includes information on the user's boarding / alighting place, refueling and / or charging place, and the waiting place of the vehicle 2, in addition to the so-called navigation map including at least the road link information on which the vehicle 2 can travel. include. In addition, pedestrian road link information for calculating the route on which the user walks may be included. The map database is used for determining a vehicle allocation route by the vehicle allocation route determination unit 13, which will be described later.

The vehicle dispatch route determination unit 13 determines the vehicle allocation route to the current position, the boarding point, and the disembarking point by using the usage request information stored in the database 12, particularly the information on the boarding point and the disembarking point, and the determined vehicle dispatch route. Information about the above is output to the increase maintenance estimation unit 14. For example, in the vehicle dispatch service using the unmanned driving vehicle of this example, the method of determining the vehicle dispatch route when the stop location of the unmanned driving vehicle is predetermined is the position information of the boarding point and the disembarking point included in the usage request information. , The nearest boarding / alighting place is determined as the boarding place and the getting-off place, respectively, by using the position information of the boarding / alighting place of the unmanned driving vehicle included in the map data. The method of determining the vehicle allocation route of the vehicle 2 is not particularly limited, and other methods may be used.

The increased maintenance estimation unit 14 inputs the vehicle allocation route determined by the vehicle allocation route determination unit 13, estimates the increase value of the maintenance necessity of the maintenance item that increases after the vehicle allocation using the usage request information, and then determines the result. Output to unit 15. In the vehicle dispatch service of this example, the maintenance items of the vehicle 2 include regular cleaning maintenance outside or inside the vehicle 2, maintenance of running energy supply (refueling or charging), parts replacement (tires, batteries, various oils, etc.). Replacement) Other maintenance Maintenance, software update (version upgrade, etc.) maintenance of the in-vehicle computer, maintenance of pasting advertisements outside or inside the vehicle are included. Hereinafter, these maintenances are also referred to as cleaning maintenance, refueling maintenance, maintenance maintenance, software update maintenance, and advertisement pasting maintenance, respectively.

The increased maintenance estimation unit 14 of the present embodiment performs cleaning maintenance, for example, assuming that the vehicle has traveled on a vehicle allocation route determined in response to a usage request from the user, regardless of the current maintenance necessity of each vehicle 2. It is a processing unit that estimates in advance how much the maintenance necessity of each of refueling maintenance, maintenance maintenance, software update maintenance, and advertisement pasting maintenance will increase (absolute value of increase in maintenance necessity). It should be noted that the vehicle management system S of the present invention does not assume that the vehicle has traveled on a vehicle allocation route determined in response to a usage request from the user, for example, based on the usage history of the user other than the boarding / alighting point and the attributes of the user. It also includes estimating in advance how much each maintenance requirement for cleaning maintenance, refueling maintenance, maintenance maintenance, software update maintenance, and advertisement pasting maintenance will increase.

Here, the maintenance necessity of cleaning maintenance can be quantified as a substitute characteristic such as the time when the user gets on the vehicle 2, the distance when the user gets on the vehicle 2, and the number of times when the user gets on the vehicle 2. For example, when the numerical value of the degree of dirtiness of the vehicle 2 per unit time is D and the boarding time of the user is T, the substitute characteristic value M of the maintenance necessity can be quantified by using D × T. Specifically, for example, the degree of contamination for normal or standard use may be set to D = 1 / hour in advance, and cleaning maintenance may be performed when M = D × T reaches 100. ..

In addition, when calculating the substitute characteristic value of the maintenance necessity of cleaning maintenance, the estimated substitute characteristic value of the maintenance necessity is calculated using the coefficient X (hereinafter, also referred to as acceleration / deceleration coefficient) for accelerating or decelerating the maintenance necessity. (Correction) may be performed. For example, if the driving environment of the vehicle allocation route (paved road, rough road, coastal area, rainy weather, etc.) can be acquired, the ratio of the degree of dirt estimated from the vehicle allocation route to the degree of dirt D in normal use is accelerated. / The deceleration coefficient X may be set, and the substitute characteristic value M = (D × X) × T for the maintenance necessity may be set. If the user's usage history (whether or not it is used cleanly) can be obtained, the ratio of the average value of the degree of dirtiness in the past use of the user and the degree of dirtiness D in normal use is accelerated / decelerated coefficient. It may be set to X, and the substitute characteristic value M = (D × X) × T for the maintenance necessity. If the user's attribute (for example, age) can be acquired, the ratio of the average value of the degree of dirtiness when the user of that age is used and the degree of dirtiness D in normal use is set as the acceleration / deceleration coefficient X for maintenance. The substitute characteristic value M = (D × X) × T of the necessity may be set.

The maintenance necessity of refueling maintenance can be quantified by using the mileage of the user on the vehicle 2, the fuel consumption, and the like as substitute characteristics. For example, when the mileage is used as a maintenance substitute characteristic value, if the vehicle allocation route can be obtained, the maintenance necessity of the refueling maintenance can be quantified by calculating the mileage from the vehicle allocation route. In addition to using the vehicle allocation route, if the user's usage history can be acquired, the maintenance necessity of refueling maintenance can be quantified by calculating the average value of the user's past mileage. In addition to using the vehicle allocation route or the user's usage history, if the user's attributes can be acquired, for example, the average mileage at the time of vehicle allocation is calculated in advance for each age group, and the average mileage is calculated from the user's age. By extracting the mileage of the age group, the maintenance necessity of refueling maintenance can be quantified.

The maintenance necessity of maintenance can be quantified as a substitute characteristic such as a mileage, a running time, and the number of times a user has boarded the vehicle 2. For example, when the mileage of the user on the vehicle 2 is used as a substitute characteristic value for maintenance and maintenance, if the vehicle allocation route can be obtained, the mileage can be calculated from the vehicle allocation route to quantify the maintenance necessity of maintenance and maintenance. Can be changed. In addition to using the vehicle allocation route, if the user's usage history can be acquired, the maintenance necessity of maintenance can be quantified by calculating the average value of the user's past mileage. In addition to using the vehicle allocation route or the user's usage history, if the user's attributes can be acquired, for example, the average mileage at the time of vehicle allocation is calculated in advance for each age group, and the average mileage is calculated from the user's age. By extracting the mileage of the age group, the maintenance necessity of maintenance can be quantified.

The maintenance necessity of software update maintenance and advertisement pasting maintenance can be quantified by using the elapsed time as a substitute characteristic. For example, if the elapsed time is used as a substitute characteristic value for software update maintenance or advertisement pasting maintenance, and if a vehicle allocation route can be obtained, the elapsed time from the usage start time to the usage end time can be calculated from the vehicle allocation route. , It is possible to quantify the maintenance necessity of software update maintenance or advertisement pasting maintenance. Further, when the user's usage history can be acquired, the maintenance necessity of the software update maintenance or the advertisement pasting maintenance can be quantified by calculating the average value of the user's past usage time. If the user's attribute (for example, age) can be acquired, the average usage time for vehicle allocation can be calculated in advance for each age group, and the average usage time for the corresponding age group can be extracted from the user's age. It is possible to quantify the maintenance necessity of software update maintenance or advertisement pasting maintenance.

The determination unit 15 determines whether or not the maintenance necessity of the maintenance item estimated by the increase maintenance estimation unit 14 is equal to or greater than the threshold value, and then outputs the result to the maintenance necessity estimation unit 16. Here, the threshold value set in the determination unit 15 may be a threshold value lower than the service spare capacity limit value, in other words, a value in the direction in which maintenance is instructed with respect to the service reserve capacity limit value. It can be set arbitrarily by the service provider. In addition, the service capacity limit value is considered to be that the quality of the maintenance target of the vehicle 2 deteriorates and the quality of the transportation service cannot be satisfied if the use is continued for the transportation service by the unmanned driving vehicle. The limit value that can be achieved. This service reserve limit value can be set to an arbitrary value by a provider of a transportation service for an unmanned driving vehicle or the like. For example, when the substitute characteristic value of the maintenance necessity of refueling maintenance is the cumulative mileage, the service reserve limit value can be set to, for example, the maximum cruising distance. Since the determination unit 15 determines whether or not the increase absolute value of the maintenance necessity estimated by the increase maintenance estimation unit 14 is equal to or more than the threshold value set for each maintenance item, the maintenance necessity to be equal to or more than the threshold value is determined. The existence means that regardless of the current maintenance necessity value of each vehicle 2, maintenance must be carried out for the maintenance item (s) for the maintenance item (s) after the vehicle is dispatched. The increased maintenance estimation unit 14 and the determination unit 15 have such a meaning.

The maintenance necessity estimation unit 16 has the maintenance necessity of the maintenance item of the vehicle that can be dispatched when the determination unit 15 determines that the maintenance necessity is equal to or higher than the threshold value for the maintenance estimated by the increase maintenance estimation unit 14. Is estimated, and the result is output to the vehicle allocation vehicle determination unit 17. Here, the maintenance necessity estimation unit 16 first extracts the vehicle 2 that can be dispatched from the plurality of vehicles 2, and the vehicle 2 that can be dispatched is the vehicle that is waiting for the provision of the transportation service among the plurality of vehicles 2. (Vehicles other than vehicles that are in use or for which usage reservations have been confirmed), and the maintenance necessity of all maintenance items estimated based on the usage request information exceeds the service capacity limit value set for each. Extract no vehicles. For example, even if the vehicle is driven on the vehicle allocation route determined by the vehicle allocation route determination unit 13 based on the boarding / alighting point included in the above-mentioned usage request information, the maintenance necessity (cumulative mileage) of the refueling maintenance exceeds the maximum cruising distance. Extract the vehicle 2 and the like that do not exist.

Further, the maintenance necessity estimation unit 16 determines that at least two maintenance items among the plurality of maintenance items, preferably the maintenance items that are determined to be equal to or higher than the threshold value by the determination unit 15, for all the vehicles of the vehicle 2 that can be dispatched thus extracted. For at least one maintenance item excluding the above, more preferably all maintenance items, it is determined whether or not the maintenance necessity becomes equal to or higher than each threshold value. The maintenance necessity of each vehicle 2 cleaning maintenance, refueling maintenance, maintenance maintenance, software update maintenance, and advertisement pasting maintenance uses the same substitute characteristic value as the processing in the increase maintenance estimation unit 14 described above, and is the final maintenance. It is determined whether or not the value added to the maintenance necessity from the date and time to the present is equal to or higher than each threshold value.

That is, the maintenance necessity of the cleaning maintenance is the time when the user got on the vehicle 2 from the last cleaning maintenance date and time to the end of the running of the vehicle allocation route, the distance when the user got on the vehicle 2, and the user got on the vehicle 2. It is possible to quantify the number of times of cleaning as a substitute characteristic. For example, when the numerical value of the degree of dirtiness of the vehicle 2 per unit time is D and the boarding time of the user is T, the substitute characteristic value M of the maintenance necessity can be quantified by using D × T.

At this time, similar to the processing in the increased maintenance estimation unit 14, when calculating the substitute characteristic value of the maintenance necessity of cleaning maintenance, the estimation substitute characteristic value of the maintenance necessity is calculated by using the coefficient X for accelerating or decelerating the maintenance necessity. May be calculated (corrected). For example, if the driving environment of the vehicle allocation route (paved road, rough road, coastal area, rainy weather, etc.) can be acquired, the ratio of the degree of dirt estimated from the vehicle allocation route to the degree of dirt D in normal use is accelerated. / The deceleration coefficient X may be set, and the substitute characteristic value M = (D × X) × T for the maintenance necessity may be set. If the user's usage history (whether or not it is used cleanly) can be obtained, the ratio of the average value of the degree of dirtiness in the past use of the user and the degree of dirtiness D in normal use is accelerated / decelerated coefficient. It may be set to X, and the substitute characteristic value M = (D × X) × T for the maintenance necessity. If the user's attribute (for example, age) can be acquired, the ratio of the average value of the degree of dirtiness when the user of that age is used and the degree of dirtiness D in normal use is set as the acceleration / deceleration coefficient X for maintenance. The substitute characteristic value M = (D × X) × T of the necessity may be set.

The maintenance necessity of refueling maintenance can be quantified as a substitute characteristic such as the cumulative mileage that the user has boarded the vehicle 2 from the final refueling maintenance date and time to the end of the running of the vehicle allocation route, or the fuel consumption amount. For example, when the cumulative mileage is used as a maintenance substitute characteristic value, if the vehicle allocation route can be obtained, the mileage calculated from the vehicle allocation route can be added to the cumulative mileage from the last refueling date to the present. It can be quantified. In addition to using the vehicle allocation route, if the user's usage history can be obtained, refueling can be performed by adding the average value of the user's past mileage to the cumulative mileage from the last refueling date and time to the present. It is possible to quantify the maintenance necessity of maintenance. In addition to using the vehicle allocation route or the user's usage history, if the user's attributes can be acquired, for example, the average mileage at the time of vehicle allocation is calculated in advance for each age group, and the average mileage is calculated from the user's age. By extracting the mileage of the age group and adding it to the cumulative mileage from the last refueling date and time to the present, the maintenance necessity of refueling maintenance can be quantified.

The maintenance necessity for maintenance is to quantify the cumulative mileage, cumulative travel time, cumulative number of rides, etc. that the user has boarded the vehicle 2 from the final maintenance maintenance date and time to the end of the vehicle allocation route as substitute characteristics. Can be done. For example, when the cumulative mileage of the user on the vehicle 2 is used as a substitute characteristic value for maintenance and maintenance, and if a vehicle allocation route can be obtained, the mileage calculated from the vehicle allocation route is changed from the final maintenance date and time to the present. By adding it to the cumulative mileage up to that point, the maintenance necessity for maintenance can be quantified. In addition to using the vehicle allocation route, if the user's usage history can be obtained, maintenance can be performed by adding the average value of the user's past mileage to the cumulative mileage from the last maintenance date and time to the present. It is possible to quantify the maintenance necessity of maintenance. In addition to using the vehicle allocation route or the user's usage history, if the user's attributes can be acquired, for example, the average mileage at the time of vehicle allocation is calculated in advance for each age group, and the average mileage is calculated from the user's age. By extracting the mileage of the age group and adding it to the cumulative mileage from the last maintenance date and time to the present, the maintenance necessity of maintenance can be quantified.

The maintenance necessity of software update maintenance and advertisement pasting maintenance can be quantified as a substitute characteristic such as the cumulative elapsed time from the last maintenance date and time to the end of the running of the vehicle allocation route. For example, when the cumulative elapsed time is used as a substitute characteristic value for software update maintenance or advertisement pasting maintenance, if a vehicle allocation route can be obtained, the elapsed time from the usage start time to the usage end time calculated from the vehicle allocation route is used. By adding to the cumulative elapsed time from the last maintenance date and time to the present, it is possible to quantify the maintenance necessity of software update maintenance or advertisement pasting maintenance. If the user's usage history can be obtained, the average value of the user's past usage time can be added to the cumulative elapsed time from the last maintenance date and time to the present for software update maintenance or advertisement pasting maintenance. The maintenance requirement can be quantified. In addition, when the user's attribute (for example, age) can be acquired, the average usage time at the time of vehicle allocation is calculated in advance for each age group, and the average usage time of the corresponding age group is extracted from the user's age. By adding to the cumulative elapsed time from the last maintenance date and time to the present, it is possible to quantify the maintenance necessity of software update maintenance or advertisement pasting maintenance.

The vehicle dispatch vehicle determination unit 17 determines whether or not the maintenance necessity of the maintenance item estimated by the maintenance necessity estimation unit 16 is equal to or higher than each threshold value, and determines the vehicle 2 having a plurality of maintenance items that are equal to or higher than the threshold value. It is determined as the vehicle 2 that responds to the usage request from the user. Here, the threshold value set in the vehicle allocation vehicle determination unit 17 is a low threshold value with respect to the service spare capacity limit value, in other words, a value in the direction in which an instruction to perform maintenance is issued with respect to the service spare capacity limit value. Often, the service provider can set it arbitrarily. Then, the result determined by the vehicle allocation vehicle determination unit 17, that is, the ID of the vehicle 2 to be allocated is output to the movement instruction unit 18 and the communication unit 19. The vehicle 2 determined by the vehicle allocation vehicle determination unit 17 is a vehicle 2 having a plurality of maintenance items in which the maintenance necessity of the maintenance item estimated by the maintenance necessity estimation unit 16 is equal to or higher than each threshold value.

In step S1 of FIG. 2, when a user uses his / her own user terminal device 3 to transmit the usage request information of the vehicle 2 to the usage request acquisition unit 11 via the communication unit 33, the usage request acquisition unit of the server 1 is used. 11 acquires the usage request information and outputs it to the database 12. This usage request information includes the user's ID, the user's intention to dispatch a vehicle, the user's current position, the user's desired boarding point and disembarking point (position information such as latitude and longitude), the user's desired vehicle allocation time, and boarding. In addition to the number of people, the user's individual attribute information such as the user's age, occupation, family structure, and preference, the user's usage history of the vehicle allocation service, the weather and other environmental information at the time of vehicle allocation, and the environment information of the vehicle allocation route are included. FIG. 3 is a diagram showing an example of the scene of step S1. For example, it is assumed that the user X requests the vehicle to be dispatched from the current position near the beach to the disembarkation point Y.

In step S2, the vehicle allocation route determination unit 13 determines the vehicle allocation route based on the usage request information of the user X stored in the database 12. FIG. 4 is a diagram showing an example of the scene of step S2, in which the vehicle allocation route determination unit 13 uses the boarding / alighting point information transmitted from the user terminal device 3 and stored in the database 12 to obtain the disembarking point Y desired by the user X. It is assumed that the vehicle allocation route R up to is decided. The vehicle allocation route R shown in the figure is a selection of the shortest route from the current location of user X to the disembarkation point Y. However, since the current location of user X is near the beach, a part of the vehicle allocation route R is seawater. It will run on the road along the bathhouse.

In step S3, the increased maintenance estimation unit 14 estimates the maintenance necessity of the maintenance items that increase due to vehicle allocation based on the usage request information of the user X stored in the database 12. FIG. 5 is a diagram showing an example of the scene of step S3, and is a diagram showing the maintenance necessity that increases due to the allocation of vehicles to the user X. In this example, the increased maintenance estimation unit 14 determines the maintenance necessity of cleaning maintenance, the maintenance necessity of maintenance maintenance, and the maintenance necessity of refueling maintenance based on the traveling conditions of the vehicle allocation route R determined by the vehicle allocation route determination unit 13. Are estimated respectively.

Here, as the substitute characteristic value of the maintenance necessity of cleaning maintenance, the degree of dirt inside and outside the vehicle is estimated by using the boarding time when traveling on the vehicle allocation route R and the acceleration / deceleration coefficient, and maintenance maintenance is required. Assuming that the substitute characteristic value of the degree and the substitute characteristic value of the maintenance necessity of the refueling maintenance are estimated using the mileage when traveling on the vehicle allocation route R, the maintenance necessity of the maintenance maintenance and the maintenance necessity as shown in FIG. The maintenance necessity of refueling maintenance increases by the value correlated with the mileage of the vehicle allocation route R, while the maintenance necessity of cleaning maintenance is because the current position of user X is near the beach. It is estimated that the acceleration / deceleration coefficient with respect to the normal degree of dirt will be large, and as a result, the maintenance requirement for cleaning maintenance will increase significantly.

Since the current location of User X is near the beach, User X is expected to be a sea bather, and it is expected that the inside of the vehicle will be contaminated with sand when boarding. Further, even if the vehicle is not a sea bather, a part of the vehicle allocation route R is a road along the beach where the traveling environment is poor against dirt, so that the degree of dirt outside the vehicle interior is expected to increase relatively. For example, even if the above-mentioned normal vehicle allocation with a degree of contamination D per unit time is 1, the acceleration / deceleration coefficient X is, for example, 20 (in this example, the acceleration coefficient) with respect to the normal 1. Substitute characteristic value M = (D × X) × T of maintenance necessity of cleaning maintenance increases 20 times.

In step S4, the determination unit 15 determines whether or not the substitute characteristic value of the maintenance necessity of each maintenance estimated in step S3 is equal to or higher than the threshold value set for each. FIG. 6 is a diagram showing an example of the scene of step S4. Due to the vehicle allocation to the user X, the maintenance necessity of maintenance and refueling are less than the respective threshold values, but the maintenance necessity of cleaning maintenance is equal to or higher than the threshold value. This is the case when it is determined that. In FIG. 6, the threshold values of the maintenance necessity of cleaning maintenance, the maintenance necessity of maintenance maintenance, and the maintenance necessity of refueling maintenance are shown as uniform values for convenience, but the actual threshold values are each. It is set for each maintenance requirement.

In step S4, if each of the substitute characteristic values of the maintenance necessity of cleaning maintenance, the maintenance necessity of maintenance maintenance, and the maintenance necessity of refueling maintenance is less than each threshold value, the process proceeds to step S7 and the vehicle is dispatched. The determination unit 17 extracts the vehicle having the shortest vehicle allocation time (travel time from the current position of the vehicle 2 to the current position of the user X) among the vehicles 2 that can be dispatched, determines the vehicle 2 as the vehicle to be dispatched, and determines the vehicle. That fact is output to the movement instruction unit 18. If the maintenance necessity of maintenance estimated based on the usage request information from user X does not increase above each threshold value, the maintenance necessity of each maintenance does not increase so much after the vehicle is dispatched, so forcibly multiple maintenance items. Rather than implementing the above at the same time, the purpose is to give priority to the dispatch time.

On the other hand, in step S4, when any of the substitute characteristic values of the maintenance necessity of cleaning maintenance, the maintenance necessity of maintenance maintenance, and the maintenance necessity of refueling maintenance is equal to or more than each threshold value, the step is taken. Proceed to S5. In such a case, maintenance is required for maintenance items that have reached at least the threshold value after the vehicle is dispatched, so priority is given to shortening the maintenance time by simultaneously performing other maintenance items. That is, in step S5, when it is determined in step S4 that there is a maintenance item in which the substitute characteristic value of the maintenance necessity that increases due to vehicle allocation is equal to or greater than the threshold value, the maintenance necessity of the current total maintenance of the vehicle that can be allocated is determined. To estimate.

FIG. 7 is a diagram showing an example of the scene (before estimation) of step S5, in which two vehicles A and B can be dispatched in response to the user X's usage request, and the current vehicles A and B, respectively. It is a figure which showed each substitute characteristic value of maintenance necessity of cleaning maintenance, maintenance necessity of maintenance maintenance, and maintenance necessity of refueling maintenance. In the example shown in FIG. 7, the substitute characteristic value for cleaning maintenance is the same for both vehicles A and B, and the substitute characteristic value for maintenance maintenance and refueling maintenance is 0 for both vehicle A and vehicle B. Is a value larger than 0. The maintenance necessity estimation unit 16 is the user X stored in the database 12 based on the respective substitute characteristic values of the maintenance necessity of the current cleaning maintenance, the maintenance necessity of the maintenance maintenance, and the maintenance necessity of the refueling maintenance. Based on the usage request information of, the maintenance necessity of each maintenance item by vehicle allocation is estimated.

Since the current locations of the vehicles A and B that can be dispatched may be different, and the vehicles A and B are often far from the current location of the user X, the vehicles A and B travel to the current location of the user X. Estimate the degree of maintenance required, taking into account the need for maintenance. FIG. 8 is a diagram showing an example of the scene (after estimation) of step S5, and after the estimation by the maintenance necessity estimation unit 16, as shown in FIG. 8, the substitute characteristic of the cleaning maintenance is the vehicle A, Both B are extremely high values, and the amount of increase in the substitute characteristic value for refueling maintenance is about the same for both vehicles A and B, but the substitute characteristic value for maintenance and maintenance is a value in which the value of vehicle B is larger than the value of vehicle A. It has become.

In step S6, the vehicle dispatch vehicle determination unit 17 determines whether or not the substitute characteristic values for all current maintenance of the vehicle dispatchable vehicles A and B estimated in step S5 are equal to or higher than each threshold value, and the threshold value or higher is reached. A vehicle B having a plurality of maintenance items is determined as a vehicle that responds to a usage request from the user X, and an output to that effect is output to the movement instruction unit 18. In the example shown in FIG. 8, in the vehicle A, only the substitute characteristic value of the maintenance necessity of cleaning maintenance is equal to or higher than the threshold value, whereas in the vehicle B, in addition to the substitute characteristic value of the maintenance necessity of cleaning maintenance, , The substitute characteristic value of the maintenance necessity of maintenance is also above the threshold value. Therefore, by allocating the vehicle B to the user X, after the vehicle allocation service is completed, two maintenances, cleaning maintenance and maintenance maintenance, can be performed at the same time, and the maintenance time can be shortened.

In step S6, if there are a plurality of maintenance items that exceed the threshold value for both the vehicles A and B shown in FIG. 8, the vehicle allocation time for the user X (from the current position of the vehicles A and B to the current position of the user X). The vehicle having the shortest running time) is extracted, the vehicle A is determined to be a vehicle to be dispatched, and a message to that effect is output to the movement instruction unit 18. Further, there are three vehicles A, B, and C that can be dispatched, and as shown in FIG. 9, the vehicle dispatch vehicle determination unit 17 has all the current vehicles A, B, and C that can be dispatched estimated in step S5. It is determined whether or not the maintenance substitute characteristic value is equal to or higher than each threshold value, and even when there are a plurality of vehicles B and C having a plurality of maintenance items that are equal to or higher than the threshold value, the vehicle allocation time to the user X (vehicles B and C). The vehicle having the shortest travel time from the current position of the user X to the current position of the user X) is extracted, the vehicle C is determined to be the vehicle to be dispatched, and the movement instruction unit 18 is output to that effect.

By the way, when the vehicle allocation vehicle determination unit 17 outputs the determined specific information of the vehicle 2 to be allocated to the movement instruction unit 18, the movement instruction unit 18 sends the determined vehicle allocation vehicle 2 to the server information reception unit 24 of the vehicle 2 via the communication unit 19. Send move instruction information. The movement instruction information includes a boarding point, a disembarking point, a vehicle allocation route, and the like of the user X, and the travel control unit 25 of the vehicle 2 travels the vehicle according to the movement instruction information to perform a vehicle allocation service.

Further, when the vehicle allocation service of the vehicle 2 is terminated, the vehicle 2 moves to a maintenance place for cleaning maintenance and maintenance maintenance. In this case, it may be accompanied by an instruction to perform cleaning maintenance and maintenance maintenance in a relatively short time as compared with normal cleaning maintenance and maintenance maintenance. Cleaning maintenance performed in a relatively short time includes cleaning limited to easily visible parts and simple cleaning with a limited number of cleanings. The instruction for shortening the maintenance time is not limited to cleaning maintenance, and may be performed for maintenance such as replenishment of running energy, replacement of parts, and software update of an in-vehicle computer.
