(for example, the map information acquisition unit 109 described below), and when the driving position state acquired by the position acquisition unit and the location registered in the location registration unit are different, the map information A position determination system is provided that includes a position determination section (for example, a position determination section 110 described below) that determines an accurate position by comparing with the map information of the acquisition section.

The present invention also provides at least one of a step of acquiring a running position state by turning on or off an ignition of a mobile object (for example, step S101 described below), and selling, maintaining, and managing the mobile object. If the driving position state acquired in the step of registering a plurality of locations and the step of acquiring the driving position state is different from the registered location, the accurate location is determined by comparing it with general map information. A position determination method is provided which includes a step of determining (for example, step S105 described below).

Then, the map information acquisition section updates the location determined by the position determination section to general map information. Furthermore, in the step of determining the accurate location, the determined location is updated to general map information.

The apparatus further includes a replacement position acquisition unit (for example, a replacement position acquisition unit 111 to be described later) that acquires the position of the movable body when a consumable part is replaced. The method also includes a step (for example, step S101, which will be described later) of acquiring the position of the movable body when replacing consumable parts.

Then, the location registration unit registers a location where the consumable part can be replaced. Furthermore, in the step of registering a plurality of locations, locations where the consumable parts can be replaced are registered.

Embodiments of the present invention will be described in detail below with reference to the drawings.

The system 1 of the embodiment includes a control processing device 100 and vehicles 200-1 to 200-n (n is an integer with n>1). Control processing device 100 and each of vehicles 200-1 to 200-n can communicate with each other via network NW. The network NW includes the Internet, a WAN (Wide Area Network), a LAN (Local Area Network), a public line, a provider device, a private line, a wireless base station, and the like.

In this embodiment, the vehicles 200-1 to 200-n are engine vehicles that run using an internal combustion engine as a drive source, or hybrid vehicles that run using an engine and a motor as drive sources. Each of the vehicles 200-1 to 200-n is parked in a parking lot used by the owner of each vehicle 200-1 to 200-n, or the engine oil of the vehicle 200-1 to 200-n is changed. The vehicle is parked at a dealership or a competitor's store.

Each of the vehicles 200-1 to 200-n is a vehicle equipped with a wireless communication function called a connected car. Vehicles 200-1 to 200-n are connected to the network NW, so that vehicle data acquired from the vehicles is input to the control processing device 100 via the network NW, and various analyzes regarding the vehicle are performed. be exposed. The vehicle data includes, for example, the location of the vehicle, the mileage of the vehicle, the residual rate of engine oil, etc. when the ignition of the vehicle is turned on. Hereinafter, vehicles 200-1 to 200-n will be described as vehicle 200 as appropriate.

The control processing device 100 is realized by a device such as a personal computer, a server, or an industrial computer. The control processing device 100 includes, for example, an engine oil residual degree acquisition unit 101, a position acquisition unit 102, a mileage acquisition unit 103, a distance at replacement time calculation unit 104, a data reception unit 105, and a replacement location registration unit 106. , the replacement location specifying unit 107, the location registration unit 108, the map information acquisition unit 109, the position determination unit 110, the replacement position acquisition unit 111, the oil change detection unit 112, the owner change determination unit 113, and the average It has a distance calculation section 114 and a determination section 115. These constitute a consumable parts replacement position identification system, replacement calculation system, position determination system, and owner change detection system.

These are realized by, for example, a hardware processor such as a CPU (Central Processing Unit) executing a program (software) stored in a storage unit (not shown). In addition, some or all of these functional units may be implemented using hardware (circuits) such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), and GPU (Graphics Processing Unit). (including circuitry), or may be realized by collaboration between software and hardware.

A storage unit (not shown) in which the program is stored is implemented by a HDD (Hard Disk Drive), a flash memory, a RAM (Random Access Memory), a ROM (Read Only Memory), or the like. The program may be stored in a removable storage medium (non-transitory storage medium) such as a DVD or CD-ROM, and may be installed by loading the storage medium into a drive device. The storage unit also includes information regarding each vehicle 200, such as the location of each vehicle 200 when the ignition of each vehicle 200 is turned on, the mileage of the vehicle 200, the residual rate of engine oil, etc. is memorized.

The engine oil residual degree acquisition unit 101 grasps the residual rate of engine oil as a consumable part of each vehicle 200, which is included in the vehicle data acquired from each vehicle 200 via the network NW.

The position acquisition unit 102 collects information on the position of each vehicle 200 (longitude and latitude values), which is the driving position state when the ignition is turned on in each vehicle 200, which is included in the vehicle data acquired from each vehicle 200. ) to obtain. Then, when the ignition is turned on after replacing the engine oil in each vehicle 200, the value of the engine oil residual rate output from the engine oil residual degree acquisition unit 101 is the value immediately after the engine oil was replaced. The value returns to the initial value, but when the oil change detection unit 112 detects that the engine oil has been replaced, the change position acquisition unit 111 determines the position of each vehicle 200 based on the engine oil. Specify as replacement position.

More specifically, the engine When the remaining amount of oil is equal to or higher than the second predetermined amount, it is determined that the engine oil remaining rate value has returned to the initial value, and the oil change detection unit 112 detects that the engine oil in the vehicle 200 has not been replaced. Detect what has been done. Here, the first predetermined amount is a variation amount when engine oil is circulating in the engine in vehicle 200. The second predetermined amount is the amount when the vehicle 200 is in an upper limit state where engine oil is sufficiently present in the engine, and is the initial value amount at which it is determined that the engine oil has been replaced.

The mileage acquisition unit 103 acquires the mileage of each vehicle 200 when the ignition is turned on in each vehicle 200, which is included in the vehicle data acquired from each vehicle 200.

The replacement distance calculation unit 104 calculates the total distance traveled by each vehicle 200 output from the mileage acquisition unit 103 and the amount of engine oil in each vehicle 200 output from the engine oil residual degree acquisition unit 101. Divide by the number of times the residual rate value returns to the initial value, which is the value immediately after replacing the engine oil. Thereby, the distance-at-replacement calculation unit 104 calculates the engine oil replacement time.

Specifically, the replacement distance calculation unit 104 obtains the total distance traveled by each vehicle 200. Further, the distance-at-change calculation unit 104 obtains from the average distance calculation unit 114 the average distance traveled from the time the engine oil is replaced until the next time the engine oil is replaced.
Here, the average distance calculation unit 114 determines that the value of the engine oil residual rate in each vehicle 200 output from the engine oil residual degree acquisition unit 101 is returned to the initial value which is the value immediately after the engine oil is replaced. In this case, two chronologically adjacent initial values, for example, as shown by "ave" in FIG. The average travel distance of each vehicle 200 (4,948 km in FIG. 3) is calculated. As the mileage, the value output from the mileage acquisition unit 103 is used.
In addition, the replacement distance calculation unit 104 divides the total distance and the number of days the vehicle 200 is used to calculate the average daily mileage of the vehicle 200 per day. Further, as shown in FIG. 3, the distance-at-replacement calculation unit 104 subtracts the most recent travel distance when the engine oil residual rate value returns to the initial value from the total distance of the vehicle 200, The most recent distance traveled by vehicle 200 after the most recent engine oil change is determined.
Then, by subtracting the most recent mileage value from the average mileage value output from the average mileage calculator 114 for the vehicle 200, the distance-at-replacement calculation unit 104 calculates the next engine oil value from the current total distance. Find the remaining travel distance until the survival rate value is expected to return to its initial value. Then, the distance-at-replacement calculating unit 104 divides the remaining mileage and the average daily mileage to determine the remaining number of days during which the next engine oil residual rate value is expected to return to its initial value. The expected date for the next engine oil change (5/4 in FIG. 3) is determined.

The data receiving unit 105 receives engine oil residual rate data from the engine oil residual rate acquisition unit 101 and the travel distance of each vehicle 200 when the ignition is turned on in each vehicle 200 from the position acquisition unit 102. and data on the mileage of each vehicle 200 when the ignition is turned on in each vehicle 200, which is included in the vehicle data acquired from each vehicle 200, from the mileage acquisition unit 103. .

Further, the data receiving unit 105 includes a map information acquisition unit 109 that has general map information including normal map information such as transportation, buildings, topography, etc., and also has a map information acquisition unit 109 that has general map information such as regular map information such as transportation, buildings, topography, etc. The exchange location registration unit 106 is stored in a storage medium (not shown).

Further, the data receiving section 105 includes an owner change determining section 113. The owner change determination unit 113 determines the remaining rate of the engine oil when the engine oil was last replaced, the position of each vehicle 200, the remaining rate of the engine oil when the engine oil was replaced this time, and the remaining rate of the engine oil when the engine oil was replaced this time. It is determined whether or not the owner of each vehicle 200 has changed by comparing the position and the position.

More specifically, in the above comparison, the owner change determination unit 113 determines that the engine oil was replaced at the same replacement position and that the time between the previous engine oil replacement and the current engine oil replacement was different. , detects that there is no ownership change of each vehicle 200, with the requirement that the time is longer than the first predetermined time. Here, as the first predetermined time, it is possible to use, for example, the number of days that is less than half of the number of days corresponding to the average mileage value output from the average distance calculation unit 114. By satisfying this requirement, the ownership of vehicle 200 has changed, and not many days have passed since the previous owner changed the engine oil, as shown in the area surrounded by the two dot-dash lines at the right end of Figure 5. Despite this, it means that the engine oil has been changed in order to be sold as a used car. In addition, although the horizontal axis in FIG. 5 shows the distance traveled by the vehicle 200, the date and time are also shown along with the horizontal axis.

In addition, in the above comparison, the owner change determination unit 113 determines that the difference in time stamps from when the ignition is turned on immediately before changing the engine oil to when the ignition is turned on immediately after changing the engine oil is a second predetermined value. It is detected that there is no ownership change of each vehicle 200, with the requirement that the time is less than the time. For example, one week can be used as the second predetermined time. By satisfying this requirement, as shown in Figure 4, if there is no owner change, the rise of the graph will be similar to the rise of other graphs, as shown in the third dashed line from the left. Compare and tilt. This means that the owner of the vehicle 200 has changed and the vehicle 200 has been sold as a used car after the engine oil has been replaced. Note that in FIG. 4 as well as in FIG. 5, the horizontal axis indicates the distance traveled by the vehicle 200, but the date and time are also indicated along with the horizontal axis.

The replacement location identifying unit 107 uses the location information registered in the replacement location registration unit 106 to identify the location where the engine oil was actually replaced. Specifically, first, the determination unit 115 determines whether the location value of the location registered in the exchange location registration unit 106 and the location value specified by the exchange location identification unit 107 are identical.

Next, based on the information on the location of each vehicle 200 from the location acquisition section 102, the exchange location specifying section 107 determines a first predetermined distance from the location indicated by a black dot with a pin in FIG. It is determined whether or not there is a store or the like registered in the exchange location registration unit 106 within the four directional range (the range surrounded by a square in FIG. 6). Here, the first predetermined distance is a distance that includes the building where the engine oil is exchanged at the dealership registered in the exchange location registration unit 106 as the dealership for the vehicle 200. As shown in FIG. 6, when it is determined that there is a store located within a first predetermined distance from the exchange point, the exchange location specifying unit 107 identifies the store or the like as the place where the engine oil was actually exchanged. Then, the determination unit 115 determines whether the value of the location registered in the exchange location registration unit 106 and the value of the location specified by the exchange location identification unit 107 are the same. If the determination unit 115 determines that they are the same, the location registered in the exchange location registration unit 106 is registered as the location where the engine oil was actually replaced.

If there is no registered location, the location determination unit 110 compares the location of each vehicle 200 with the location of a competing store, etc. included in the general map information of the map information acquisition unit 109. to determine the exact location. The determined accurate position is then updated by the map information acquisition unit 109 into the general map information of the map information acquisition unit 109 as a new engine oil change location for each vehicle 200 from the position acquisition unit 102. The location registration unit 108 registers a location that sells, maintains, or manages the vehicle 200 as a competing store in the exchange location registration unit 106.

Next, a method for specifying the position at the time of replacement of consumable parts, a method for calculating the time of replacement, a method for determining the position, and a method for detecting a change in ownership, which are carried out under the control of the control processing device 100, will be described.
First, in step S<b>101 , the engine oil residual degree acquisition unit 101 of the control processing device 100 collects the residual amount of engine oil from each vehicle 200 . The process of the control processing device 100 then proceeds to step S102.

In step S102, the control processing device 100 determines that the residual amount of engine oil received by the data receiving unit 105 from the engine oil residual degree acquisition unit 101 has increased by a first predetermined amount or more compared to the previous collection, and It is determined whether the remaining amount of engine oil is equal to or greater than a second predetermined amount.

In step S102, the control processing device 100 determines that the remaining amount of engine oil has increased by a first predetermined amount or more compared to the previous collection, and the remaining amount of engine oil is equal to or more than a second predetermined amount. If so (step S102: YES), the process of the control processing device 100 proceeds to step S103. When the control processing device 100 determines that the remaining amount of engine oil has increased by a first predetermined amount or more compared to the previous collection, and the remaining amount of engine oil is not more than a second predetermined amount (step S102: NO), the process of the control processing device 100 returns to step S101.

In step S103, the oil exchange detection unit 112 of the control processing device 100 detects that the engine oil has been exchanged, and the exchange position acquisition unit 111 detects the position of the vehicle 200 where the engine oil has been exchanged. Specify as the engine oil change location. The process of the control processing device 100 then proceeds to step S104.

In step S104, the control processing device 100 converts the position where the engine oil change was detected from the position acquisition unit 102 received by the data reception unit 105 when the ignition is turned on in the vehicle 200 into a “replacement point (replacement point)”. The time at which engine oil replacement is detected is defined as the "replacement timing (at time of replacement)". Furthermore, the average distance calculation unit 114 calculates the average distance traveled by the vehicle 200 in which the engine oil has been replaced.
Further, by acquiring the mileage of each vehicle 200 from the mileage acquisition unit 103 when the ignition is turned on in the vehicle 200, the mileage at replacement calculation unit 104 determines the value of the remaining rate of engine oil for the next time. Find the remaining number of days expected to return to the initial value. Then, the next date when the residual rate of engine oil is expected to return to its initial value is stored in a storage medium (not shown). The process of the control processing device 100 then proceeds to step S105.

In step S105, the replacement location identifying unit 107 of the control processing device 100 identifies the engine oil replacement location, and the determination unit 115 of the control processing device 100 determines the location value and the location registered in the replacement location registration unit 106. The identity of the location value specified by the exchange location specifying unit 107 is determined. That is, if it is determined that there is a store within the first predetermined distance from the engine oil exchange point (step S105: YES), the process of the control processing device 100 proceeds to step S106. If it is determined that there is no store within the first predetermined distance from the exchange point (step S105: NO), the process of the control processing device 100 proceeds to step S108.

In step S106, the control processing device 100 determines that the place where the engine oil was replaced is a dealer. The process of the control processing device 100 then proceeds to step S107. In step S107, the control processing device 100 records one piece of data indicating that the engine oil of the vehicle 200 was changed at a dealership in the exchange location registration unit 106, and records the dealership. The process of the control processing device 100 then proceeds to step S110.

In step S108, the control processing device 100 determines that the place where the engine oil was changed is not a dealership but a competing shop. The process of the control processing device 100 then proceeds to step S109. In step S109, the control processing device 100 records one piece of data indicating that the vehicle 200 had its engine oil changed at a competing store in the replacement location registration unit 106, and registers the competing store.
Additionally, the map information acquisition unit 109 adds the accurate position determined by the position determination unit 110 based on the position of each vehicle 200 from the position acquisition unit 102 to the general map information of the map information acquisition unit 109. Updated as a place to change engine oil.

Specifically, as shown in FIG. 7, the number of engine oil changes performed at competing stores such as automobile repair shops, tire shops, and gas stations is registered so as to be displayed on a map together with the stores. For example, as shown in FIG. The number of days until the next engine oil change (for example, "remaining number of replacement days: 25 days", etc.) is recorded so that it can be displayed on a map. The process of the control processing device 100 then proceeds to step S110. In addition to the above, the predicted date of the next engine oil change may be displayed on the map.

In step S110, the control processing device 100 compares the location where the vehicle 200 had its engine oil replaced last time and the location where its engine oil was replaced this time. Specifically, it is as shown in Table 1.

In other words, if the engine oil was changed at the dealership last time, and if the engine oil is also changed at the dealership this time, the vehicle 200 continues to be managed by the dealership. A status of “management maintenance” indicating the state is registered in the exchange location registration unit 106.
In addition, if the engine oil was changed at the previous dealership, and if the engine oil was changed this time at a competing shop or if the owner changed the engine oil himself, A status of “currently leaked” indicating that the vehicle 200 is no longer under the control of the dealer when changing the oil is registered in the oil change location registration unit 106.
In addition, if the engine oil was changed last time at a competing shop or by the owner himself, and if the engine oil is changed at the dealership this time, the dealership will not be able to manage the vehicle 200 again. A status of “recapture” indicating the state in which the exchange is to be carried out is registered in the exchange location registration unit 106.
Also, if the engine oil was changed at a competing shop or by the owner himself last time, and if the engine oil was changed at a competing shop this time as well, or if the owner himself changed the engine oil. Subsequently, a status of "Continued leakage" indicating that the vehicle 200 is no longer under the control of the dealership is registered in the exchange location registration unit 106. The process of the control processing device 100 then proceeds to step S111.

In step S111, the owner change determination unit 113 of the control processing device 100 determines whether the engine oil has been replaced after a first predetermined period of time when the amount of oil has decreased, or whether the time stamp between the previous collection time and the current collection time has passed. It is determined whether the difference is less than a second predetermined time.

That is, in the above comparison, the owner change determination unit 113 determines that the replacement position (effect location) where the engine oil was replaced is the same, and the time between the previous engine oil replacement and the current engine oil replacement is different. , it is determined whether or not the first predetermined time is longer than the first predetermined time. In addition, the owner change determination unit 113 determines that the time stamp difference between turning on the ignition before changing the engine oil and turning on the ignition immediately after changing the engine oil is less than a second predetermined time. Determine whether or not.

If any of the determinations is positive (S111: YES), the process of the control processing device 100 proceeds to step S112. If either determination is negative (S111: NO), the process of the control processing device 100 proceeds to step S113.

In step S112, the owner change determination unit 113 of the control processing device 100 records on a recording medium (not shown) that there is no owner change. Then, the processing of the control processing device 100 ends.

In step S113, the owner change determination unit 113 of the control processing device 100 records on a recording medium (not shown) that there is an owner change. Then, the processing of the control processing device 100 ends.

According to this embodiment, the following effects are achieved.
In this embodiment, the remaining rate of the engine oil as a consumable part of the vehicle 200 is grasped, the ignition of the vehicle 200 is turned on to obtain the position as the driving position state, and the remaining rate of the engine oil is determined. and location data. Then, when the value of the residual rate of engine oil data returns to the initial value depending on the running state of the vehicle 200, the position of the moving object is specified.

Thereby, when the value of the residual rate data of the engine oil returns to the initial value, it becomes possible to specify the position where the data has returned to the initial value. Therefore, by regarding the location of the returned location as the location of the engine oil exchange location, accurate market share can be obtained. In addition, it will be possible to understand the competitive shops that change engine oil and the customer mindset, and it will be possible to win back lost customers using an optimal approach, which will ultimately make it possible to improve the parts business income of the manufacturer of vehicle 200. Become.

Furthermore, in the present embodiment, in the process of identifying the location of the vehicle 200, the data receiving unit 105 can use general map information and information in which locations where engine oil can be replaced are registered. This makes it possible to identify the location where the vehicle 200 actually replaced the engine oil in the general map information by comparing it with general map information.

Furthermore, in the present embodiment, in the step of identifying the location of the vehicle 200, the replacement location identifying unit 107 identifies the location where the engine oil was actually replaced from the information in which locations where engine oil can be replaced are registered. This makes it possible to know at which of the already registered locations where engine oil can be replaced, the engine oil is being replaced.

Furthermore, in the present embodiment, the determination unit 115 determines whether the value of information in which the place where engine oil can be replaced is registered is the same as the value of the information of the place where engine oil was actually changed. This makes it possible to know whether or not engine oil has been replaced at a location where engine oil can be replaced, which is already registered.

Further, in the present embodiment, the mileage is acquired by turning on the ignition of the vehicle 200, the residual rate of engine oil provided in the vehicle 200 is grasped, and the value of the data of the residual rate of engine oil is set to the initial value. When the vehicle 200 returns to its initial value twice, the average value of the distance traveled between two adjacent returns to the initial value is calculated, and the total distance traveled by the vehicle 200 and the residual rate of engine oil data are returned to their initial values. The engine oil replacement time is calculated by dividing the number of times the engine oil is replaced.

As a result, the residual rate of engine oil can be grasped not only when the vehicle 200 is being managed and maintained, but also when the vehicle has left the vehicle or when the owner has changed the engine oil himself. It is possible to understand the oil replacement history and calculate the next engine oil replacement time. Therefore, it is possible to predict the next engine oil replacement time for all vehicles 200, including the departed vehicle 200 for which it was not possible to know the next engine oil replacement time in the past. As a result, it becomes possible to find potential customers who are at the optimal timing for engine oil changes from around stores such as dealers and competing stores, and increase sales of engine oil as a component by developing an efficient sales promotion approach. It becomes possible to realize this. Further, by detecting the position by turning on the ignition of the vehicle 200, it is possible to know the customer's living area.

More specifically, for example, as shown in FIG. 9, it is possible to obtain the customer defection rate of the vehicle 200 in each city. The shaded area on the right side of the graph for each city in FIG. 9 indicates the defection rate.
Furthermore, for example, as shown in FIG. 10, it is possible to clarify at what timing the engine oil is replaced with respect to the mileage of the vehicle 200. Figure 10 shows the number of vehicles 200 in one city whose engine oil has been changed based on the mileage. It has become possible to clarify that there are many
By aggregating this information for different cities, it can be seen that the trends in engine oil replacement timing differ, as shown in Figure 11, so it can be made clear whether or not early sales promotion is desirable. becomes possible.
Furthermore, since it is possible to know the day of the week when the engine oil was replaced, for example, as shown in FIG. It is possible to classify the store into whether it is a commercial store or a competing store, and to clarify this in a graph. This makes it possible to make it clear that the customer is defecting on Tuesdays and Thursdays, when stores are often closed.

Furthermore, in the present embodiment, the position acquisition unit 102 acquires the position of the vehicle 200 at the time of returning to the initial value. This makes it possible to know the location of the vehicle 200 where the engine oil has been replaced.
