Description

The present invention relates to a vehicle management system and a vehicle management method.

In a car-sharing service where multiple people use one car, for members who have a large number of complaints, a list of vehicles arranged in order of newest maintenance end date and vehicle registration date can be displayed on the screen, making it relatively clean. There is known a car sharing reservation system that makes it easier for the member to select a vehicle in a bad state, suppresses complaints from the member, and eliminates the discomfort that the member feels about the car sharing service (Patent document 1).

Japanese Patent No. 5537217

However, the conventional car sharing reservation system described above does not give any consideration to when the vehicle should be cleaned. That is, the above-described conventional car sharing reservation system is a system that simply displays vehicles with new maintenance end dates and vehicle registration dates, that is, vehicles that are close to the cleaning date and are close to new vehicles on the screen in order from the top. , the usage situation is not considered until it is provided to the member who made the reservation. Therefore, even if you reserve a car that is close to the cleaning date and looks like a new car, it is not uncommon for the car to get dirty due to being used by other members before the use date, so the car that is actually clean will appear on the screen. Not sure if it is displayed. For example, in the case of services that use unmanned self-driving cars, it is likely that there will be an increase in the use of drop-off types. There is also the question of how many people should be secured.

A problem to be solved by the present invention is to provide a vehicle management system and a vehicle management method for notifying an appropriate cleaning time of a vehicle or cleaning the vehicle.

In the present invention, when at least one vehicle is used by one or more users, vehicle usage information is acquired, the degree of contamination of the vehicle is estimated based on the vehicle usage information, and the degree of contamination is a predetermined threshold value. The above problem is solved by notifying the vehicle that it needs to be cleaned or by cleaning the vehicle when it is determined that the vehicle has reached

According to the present invention, the degree of contamination of the vehicle is estimated based on vehicle usage information, and when it is determined that the degree of contamination has reached a predetermined threshold value, cleaning of the vehicle is prompted. It is possible to provide a vehicle having a level of cleanliness or higher.

The vehicle information database 11 is a database that stores dynamic vehicle information transmitted from the vehicle information transmission unit 23 of the vehicle 2 at predetermined time intervals, in addition to static information such as vehicle type, vehicle registration date, etc., which are known in advance. is. As will be described later, since there are a plurality of vehicles 2, information on all vehicles existing within a predetermined service area is stored here. The vehicle information includes position information of the vehicle 2, vehicle orientation, vehicle speed, door lock and door open/closed status, seat belt sensor value, and various vehicle statuses such as whether the vehicle is automatically driven. In addition, information related to remote monitoring of unmanned autonomous driving, such as whether vehicle requests can be received, whether the vehicle is being cleaned, whether there are passengers or not, the number of passengers, and whether the vehicle has arrived at the destination specified by transportation instructions, is also stored in the same vehicle ID. stored in association with each other.

The map database 12 includes a so-called navigation map containing at least road link information on which the vehicle 2 can travel, as well as information on user boarding/alighting locations, refueling and/or charging locations, and waiting locations for the vehicle 2 . In addition, it may include pedestrian road link information for calculating the route that the user walks.

The vehicle request management unit 13 receives usage request information for the vehicle 2 from the user terminal 3 and outputs the usage request information for the vehicle 2 to the vehicle planning unit 14 . Also, it receives usage request result information corresponding to the usage request information from the vehicle planning unit 14 and transmits the usage request result information to the user terminal 3 .

The vehicle planning unit 14 uses the usage request information of the vehicle 2 output from the vehicle request management unit 13 and the vehicle information stored in the vehicle information database 11 to calculate and calculate the vehicle allocation plan information of the vehicle 2. The vehicle allocation plan information of the vehicle 2 is output to the vehicle request management unit 13 and the vehicle reservation unit 15 . Here, the method of calculating the dispatch plan information of the vehicle 2 will be described. Then, the closest boarding and alighting places are determined as the boarding and alighting places, respectively. Next, the vehicle 2 closest to the boarding place is determined as the allocated vehicle among all the vehicles 2 for which the use request information of the vehicle 2 can be received. Note that the method of calculating the vehicle allocation plan information of the vehicle 2 is not particularly limited, and other methods may be used.

The vehicle reservation unit 15 uses the vehicle allocation plan information of the vehicle 2 output from the vehicle planning unit 14 and the vehicle information contained in the vehicle information database 11 to determine the travel route to the point where the user is picked up and the point where the user is dropped off. is calculated, other information necessary for operating an unmanned automatic vehicle is added to this, and the route is transmitted to the server information receiving unit 24 of the vehicle 2 .

Regarding the vehicle 2 assigned to the user's usage request information, the usage information acquisition unit 16 retrieves the last cleaning associated with the vehicle ID of the vehicle 2 from the vehicle information of the vehicle 2 stored in the vehicle information database 11 . Acquire information on the date and time when the cleaning was performed (hereinafter also referred to as the final cleaning date and time). The last cleaning date and time acquired here may include a plurality of pieces of information, such as the date and time when only the vehicle exterior was washed, only the vehicle interior was cleaned, or both the exterior and interior of the vehicle were cleaned. The date and time of the last cleaning can be directly input by the person in charge of cleaning if there is a terminal device that can access the vehicle information database 11, or can be input by the person in charge of remote monitoring who obtains information from the person in charge of cleaning. Alternatively, a terminal device mounted on the vehicle 2 may be used to input the execution of cleaning, and the vehicle information transmission unit 23 may store the information in the vehicle information database 11 . In this embodiment, the degree of contamination of the vehicle 2 up to the present is estimated from the last cleaning date and time, but cleaning is performed starting from a reference date different from the last cleaning date and time, for example, the initial registration date of the vehicle 2. The degree of contamination of the vehicle 2 up to the present may be estimated by decreasing the degree of contamination each time.

The contamination level estimation unit 17 estimates the contamination level of the vehicle 2 based on the vehicle usage information. More specifically, the degree of contamination of the vehicle 2 is estimated based on the usage information of the vehicle 2 from the last cleaning date and time acquired by the usage information acquiring unit 16 to the present. Here, in this embodiment, as a substitute characteristic of the usage information of the vehicle 2, one of the time the user got on the vehicle 2, the distance the user got on the vehicle 2, the number of times the user got on the vehicle 2, or An integrated value of a combination of two or more of these is used. A specific example of the contamination level estimation method will be described later.

The judgment unit 18 judges whether the degree of contamination estimated by the contamination degree estimation unit 17 exceeds a threshold arbitrarily set by the service provider. When the degree of contamination estimated by the degree of contamination estimation unit 17 exceeds the threshold, it is determined that the vehicle 2 needs cleaning, and the degree of contamination estimated by the degree of contamination estimation unit 17 exceeds the threshold. If not, it is determined that the vehicle 2 does not require cleaning.

When the determination unit 18 determines that the cleaning of the vehicle 2 is necessary, the notification unit 19a notifies that effect. Although not particularly limited, the notification destination of the notification unit 19a includes a transportation service providing company or its person in charge, a cleaning company or its person in charge, and the like. The notification method by the notification unit 19a includes a method that enables visual or auditory recognition, such as display on a display, lighting of an indicator provided at a predetermined position of the vehicle 2, notification by sound including voice, and the like.

The cleaning unit 19b cleans the vehicle 2 when the determination unit 18 determines that the vehicle 2 needs to be cleaned. Specifically, the cleaning execution unit 19b refers to the map database 12 to calculate a travel route from the current position to the cleaning place, and transmits the travel route to the vehicle 2 with an unmanned automatic driving function. The vehicle 2 inputs the travel route transmitted from the cleaning implementation unit 19b to the travel control unit 25 via the server information reception unit 24, travels to the cleaning place using the automatic operation function, and automatically moves the vehicle 2. Carry out cleaning.

For cleaning the vehicle 2, an automatic car wash including a car washing robot can be used for cleaning the exterior of the vehicle interior, and a cleaning robot can be used to automatically clean the interior of the vehicle. Alternatively, the vehicle 2 may be cleaned by the cleaning staff of the cleaning company by using the automatic operation function to drive the vehicle to the cleaning location and stop at the predetermined cleaning location. Alternatively or in addition to this, the cleaning of the vehicle 2 by the cleaning unit 19b includes jetting the windshield washer of the vehicle 2 to operate the wiper to wash the front windshield, the rear windshield and/or the headlamps. It also includes doing

Note that when the determination unit 18 determines that the cleaning of the vehicle 2 is necessary, at least one of the notification unit 19a and the cleaning execution unit 19b may be activated, and only the notification unit 19a is activated. , the case where only the cleaning execution part 19b is made to function, and the case where both the notification part 19a and the cleaning execution part 19b are made to function are included.

《Vehicle》
The vehicle 2 is a service vehicle that is provided in response to a request for use from a user, and in this embodiment, a plurality of vehicles are assumed to be arranged in an area where the service is developed. However, as mentioned above, it is not intended to exclude non-service vehicles such as private cars and company cars. The vehicle 2 includes a vehicle position calculator 21 , a vehicle state detector 22 , a vehicle information transmitter 23 , a server information receiver 24 and a travel controller 25 .

The vehicle position calculator 21 calculates the position of the vehicle 2 and outputs it to the vehicle information transmitter 23 . The vehicle position calculator 21 is, for example, an ECU connected to a GPS/INS sensor, and outputs latitude/longitude position information output from the GPS/INS sensor at regular time intervals (for example, 100 msec). A method of calculating the position information is not particularly limited, and for example, other methods capable of specifying the position, such as map matching based on map data, may be used.

Whether the vehicle state detection unit 22 can receive usage request information for the vehicle 2, including various vehicle states such as vehicle speed, door lock and door open/closed state, seat belt sensor value, and whether or not the vehicle is being driven automatically. It also detects information related to remote monitoring of unmanned automatic driving, such as whether it is cleaning, whether it is cleaning, whether there are passengers and the number of passengers, whether it has arrived at the destination of the movement instruction, etc., and outputs it to the vehicle information transmission unit 23.

The vehicle information transmission unit 23 is, for example, an in-vehicle device equipped with a 4G/LTE mobile communication function, and transmits information output from the vehicle position calculation unit 21 and the vehicle state detection unit 22 via CAN, LAN, or the like for a certain period of time (for example, 100 msec) to the vehicle information database 11 of the server 1 .

The server information receiving unit 24 is, for example, an in-vehicle device equipped with a 4G/LTE mobile communication function. It receives information necessary for operating an unmanned autonomous vehicle, including various travel routes such as the travel route to the cleaning site, the travel route to the cleaning site, and other information.

The travel control unit 25 is a controller that automatically controls various electric devices including a travel drive source (engine and/or motor), a steering mechanism, a braking mechanism, a direction indicator, and a wiper of the vehicle 2. 15 and the cleaning execution unit 19b, such as the route to the waiting place, the travel route to the point where the user rides, the travel route to the cleaning place, etc. automatically controls the travel drive source, steering mechanism, braking mechanism, and various electrical devices of the vehicle 2 based on the necessary information.

《User Terminal》
The user terminal device 3 is a terminal device used by a user who desires transportation services to make a usage request, for example, a mobile terminal device such as a smart phone. / The server 1 is accessed via a telecommunication network such as LTE or WiFi (registered trademark). The user terminal 3 is not particularly limited, and in addition to the means described above, other implementation methods may be used, such as issuing a usage request via the Internet from a personal computer implemented as WEB application software.

Based on the input by the user, the vehicle 2 utilization request information described below is transmitted to the vehicle request management unit 13 . It also receives usage request result information corresponding to the usage request information from the vehicle request management unit 13 and presents it to the user via a display or the like.

The vehicle 2 use request information transmitted to the vehicle request management unit 13 includes a departure point and a destination, the destination is obtained by input from the user, and the departure point is obtained by the user's position information or input from the user. You may In addition, additional information such as designation of waypoints, designation of boarding/alighting points, number of passengers, reservation time, and whether or not to share a ride may be included.

The usage request result information transmitted from the vehicle request management unit 13 includes information for identifying the user's pick-up and drop-off locations, the current position of the reserved vehicle 2, and the reserved vehicle. Based on the calculated information, additional information such as the arrival time of the vehicle at the pick-up location, the travel time from the pick-up location to the drop-off location, and the recommended walking route for the user to move to the pick-up location may be included.

Next, a specific processing flow will be described with reference to FIGS. 2 and 3. FIG. This processing flow is preferably executed periodically, such as at predetermined time intervals or each time use by one user ends. In the following description, an example in which the user's riding time in the vehicle 2 is used as an estimated substitute characteristic value for the degree of contamination will be described, but the user's riding distance and the user's riding count can also be processed in the same way. .

In step S1 of FIG. 3, the vehicle information database 11 is referenced for the vehicle 2 assigned by the vehicle planning unit 14, and the last cleaning date and time is extracted, and the process proceeds to step S2. In step S2, the total time of the user's boarding time from the last cleaning date to the present is set as an estimated substitute characteristic value (for example, A=100 minutes) of the degree of contamination, and the process proceeds to step S3.

In step S3, a threshold value B (for example, B=120 minutes) of the total riding time set by the service provider is compared with the estimated substitution characteristic value A for the degree of contamination calculated in step S2. If the characteristic value A is larger (A≧B), the process proceeds to step S4. In step S4, the notifying section 19a notifies that cleaning is necessary, and instead of or in addition to this, the cleaning performing section 19b performs cleaning.

FIG. 4 is a graph showing the relationship between the cleanness of the vehicle 2 and the usage time, explaining an example of the threshold value of the degree of contamination used by the determination unit 18 of the server 1. As shown in FIG. FIG. 4(a) is a graph showing the cleanliness of the vehicle at regular regular cleaning timings, and the regular cleaning timing T1 is a value determined based on an empirical rule. If the timing of periodic cleaning is determined based on an empirical rule in this way, since the actual usage situation of the vehicle 2 is not taken into consideration, the cleanliness of the vehicle 2 enters the level zone where dirt is conspicuous. It's time to clean up. On the other hand, FIG. 4(b) is a graph showing the case of setting the threshold used in the determination unit 18 according to the present embodiment. In this case, the total value A of the riding time of the vehicle is calculated as a substitute characteristic value for estimating the degree of contamination. Necessary notification and/or cleaning is performed. By doing so, the cleanliness of the vehicle 2 is suppressed from entering a level zone where dirt is conspicuous.

In step S3, the threshold value B for the total boarding time set by the service provider is set to a threshold value B1 for cleaning the vehicle interior (for example, B1=120 minutes) and a threshold value B2 for cleaning the vehicle exterior (for example, B2=180 minutes). may be set, and by comparison, notification that the vehicle interior needs cleaning and / or cleaning, and notification that the vehicle exterior needs cleaning and / or cleaning can also be divided into

For the estimated substitute characteristic value of the degree of contamination, one of the time the user has ridden the vehicle 2, the distance the user has ridden the vehicle 2, and the number of times the user has ridden the vehicle 2 can be used. An integrated value of a combination of two or more may be used. For example, when combining the distance the user has ridden the vehicle 2 and the number of times the user has ridden the vehicle 2, in step S2 of FIG. A value obtained by multiplying the total value by the number of times the user has boarded the vehicle 2 from the last cleaning date and time to the present is calculated as an estimated substituting characteristic value for the degree of contamination, and the process proceeds to step S3. Then, in step S3, a value obtained by multiplying the threshold value of the total travel distance set by the service provider by the threshold value of the number of times of travel is calculated, and the result is compared with the estimated substitute characteristic value of the degree of dirt calculated in step S2. .

In calculating the estimated substitute characteristic value of the degree of contamination in step S2 in FIG. correction). FIG. 3 is a flow chart showing the subroutine of step S2 in FIG. This processing flow is another example (extended function) of the contamination level estimation unit 17 in FIG. The acceleration/deceleration coefficient X is the date and time when the user used the vehicle 2 from the last cleaning date to the present, the weather at the date and time when the user used the vehicle 2, the characteristics of the travel area where the user used the vehicle 2, and the vehicle 2. One of the utilized user characteristics or a combined value of two or more of these can be used.

In step S21, the degree of contamination (riding time) from the last cleaning date of the assigned vehicle 2 extracted in step S2 of FIG. 2 to the present is obtained, and the process proceeds to step S22. At step S22, it is determined whether the acceleration/deceleration coefficient X is to be applied. Here, the numerical value of the acceleration/deceleration coefficient X can be set to any value by the service provider.

For example, when the date and time when the user uses the vehicle 2 is used as the acceleration/deceleration coefficient X, X=1.2 for the lunch time zone and X=1.5 for the dinner time at the end of the year. If vehicle 2 is used during meal times, the interior of the vehicle is more likely to get dirty than when it is used at other times. In addition, the frequency of using the vehicle 2 for eating out increases during the dinner hours at the end of the year and the beginning of the year.

Also, when using the weather of the date and time when the user uses the vehicle 2 as the acceleration/deceleration coefficient X, X=1.0 (that is, not applicable) when the weather is fine, and X=1.5 when it rains. . The weather information to be acquired can be determined from the operating information of the wipers of the vehicle 2 or the like. This is because when the vehicle 2 is used in rainy weather, the outside of the vehicle is more likely to be dirty than when the vehicle 2 is used in fine weather, and the user's clothes and shoes are more likely to stain the interior of the vehicle. be.

In addition, as the acceleration/deceleration coefficient X, when the user uses the characteristics of the driving area using the vehicle 2 (such as the area where the transportation service is developed), the urban area is set to X = 1.0 (that is, not applicable), and the tourist area is set to X=1.2, or X=1.5 for mountainous areas or unpaved roads. While there are many paved roads in urban areas, there are many unpaved roads in mountainous areas, so when driving in mountainous areas or on unpaved roads, the outside of the vehicle is more likely to get dirty than when driving in urban areas. Because it becomes Also, when traveling in a tourist spot, there are relatively many opportunities to eat food sold at the tourist spot in the vehicle interior, and the possibility of the vehicle interior becoming dirty is higher than in the city area.

In addition, when using the characteristics of the user who uses the vehicle 2 as the acceleration/deceleration coefficient X, the information in the member database (which may be stored in the vehicle information database 11) that manages the user information is referred to, and For example, X=1.2 for a user who leaves garbage in the passenger compartment, and X=0.8 for a user who leaves after cleaning up the garbage in the passenger compartment. FIG. 5 is a data sheet showing an example of member information registered in the vehicle information database 11 of FIG. 1 or the like. As member information, in addition to the information necessary for using the service, including the personal information of the member, the number of times the garbage is returned and the number of times the garbage is brought back is analyzed and recorded from the video data captured by the in-vehicle camera. This is used as material for calculating the coefficient X of the service provider.

When using the characteristics of the user who uses the vehicle 2 as the acceleration/deceleration coefficient X, the characteristics of not only the person making the reservation to use the vehicle 2 but also the fellow passengers may be considered. For example, X=1.0 (that is, not applicable) when the fellow passengers are mostly adults, and X=1.5 when there are many children such as elementary and junior high school students among the fellow passengers. This is because if there are many small children among the passengers, there is a high possibility that the interior of the vehicle will become dirty. If the fellow passenger is registered in the member database, the characteristics of the fellow passenger may be extracted from the data sheet shown in FIG.

As the acceleration/deceleration coefficient X, the date and time when the user used the vehicle 2 from the last cleaning date to the present, the weather at the date and time when the user used the vehicle 2, the characteristics of the driving area where the user used the vehicle 2, Any one of the characteristics of the user using the vehicle 2 can be used, or a combined value of two or more of these can be used. For example, when the elements of the acceleration/deceleration factor X occur simultaneously, such as when the weather is rainy and the driving area is a tourist spot, the value obtained by multiplying the acceleration/deceleration factor X of each factor is the final acceleration/deceleration factor. A deceleration coefficient X may be used.

Returning to FIG. 3, in step S22, if it is determined that the acceleration/deceleration coefficient X is not applied (that is, X=1.0), the process is terminated. Proceeding to step S23, the acceleration/deceleration coefficient X to be applied is multiplied by the estimated substitute characteristic value of the degree of contamination, and then proceeding to step S3 in FIG.

As described above, according to the vehicle management system S and the vehicle management method of the present embodiment, the degree of contamination of the vehicle 2 is estimated based on the usage information of the vehicle 2, and it is determined that the degree of contamination has reached the predetermined threshold. In this case, cleaning of the vehicle 2 is urged, so it is possible to provide the user with a vehicle 2 having cleanliness of a certain level or higher. As a result, the number of complaints from members can be reduced, and the discomfort felt by members about transportation services can be eliminated.

Further, according to the vehicle management system S and the vehicle management method of the present embodiment, the degree of contamination of the vehicle 2 is estimated based on the usage information of the vehicle 2 from the last cleaning date to the present. Accuracy is improved, and vehicles 2 having a certain level or higher of cleanliness can be more reliably provided to users.

Further, according to the vehicle management system S and the vehicle management method of the present embodiment, one of the time the user got into the vehicle 2, the distance the user got into the vehicle 2, the number of times the user got into the vehicle 2, or The degree of contamination of the vehicle 2 is estimated based on a combination of two or more of these, that is, a more specific substitute characteristic value for estimating the degree of contamination. It is possible to more reliably provide a vehicle 2 having a certain level or higher of cleanliness.

Further, according to the vehicle management system S and the vehicle management method of the present embodiment, the degree of contamination is estimated using the coefficient X that accelerates or decelerates the degree of contamination. degree is estimated. As a result, the accuracy of estimating the degree of contamination is further improved, and it is possible to more reliably provide the user with a vehicle 2 having cleanliness of a certain level or higher.

Further, according to the vehicle management system S and the vehicle management method of the present embodiment, the coefficient X for accelerating or decelerating the degree of contamination is the date and time the vehicle 2 was used, the weather at the date and time the vehicle 2 was used, and the The acceleration/deceleration coefficient X is set more specifically because it is set based on one or a combination of two or more of the characteristics of the driving area and the characteristics of the user who uses the vehicle 2 . As a result, the accuracy of estimating the degree of contamination is further improved, and it is possible to more reliably provide the user with a vehicle 2 having cleanliness of a certain level or higher.

Further, according to the vehicle management system S and the vehicle management method of the present embodiment, the vehicle exterior threshold for determining the degree of dirt outside the vehicle interior of the vehicle 2 and the degree of dirt inside the vehicle interior of the vehicle 2 are used as the predetermined thresholds. Since the cleaning timing of the vehicle 2 is included, it is possible to disperse the cleaning timing of the vehicle 2 and shorten the cleaning time, which is the period during which the service is suspended.
