Description

The present invention relates to a service information notification system for notifying service information recommending replacement of consumables used in a vehicle, and a data structure used in the service information notification system.

A system for notifying the replacement timing of automobile parts (consumables) that are consumed according to use is known (see Patent Document 1).

Specifically, the in-vehicle terminal acquires the mileage of the vehicle from the previous replacement timing of the consumables, and compares the acquired mileage with the reference data. When the mileage and the reference data match and the campaign period indicated by the service information transmitted from the information providing server is applicable, the in-vehicle terminal receives the incoming service information that recommends the replacement of consumables (user). ).

Japanese Unexamined Patent Publication No. 2005-100155

The system described above assumes that if the consumables are replaced, the authorized dealer will reset the previous replacement timing for the vehicle. Therefore, if the consumables are replaced at a place other than the regular dealer (such as a car accessory store), it becomes difficult to determine the next replacement timing.

In addition, the need for service information that recommends replacement of consumables varies from individual user to individual user. This is because the place to replace the consumables (authorized dealer or car supply store) and the timing to actually replace the consumables differ depending on the user.

Therefore, notifying the less necessary user of the service information wastes the resources of the system and the communication network as a result. Moreover, such a user may find the service information annoying.

Therefore, the present invention has been made in view of such a situation, and predicts the replacement timing of consumables used in a vehicle such as an automobile without using the previous replacement timing, and for each user. The purpose is to provide a service information notification system that can recommend replacement of consumables at a more appropriate timing, and a data structure of user data used in the service information notification system.

The service information notification system according to one aspect of the present invention notifies service information recommending replacement of consumables used in the vehicle. The service information notification system acquires consumable consumption status data from the vehicle, stores it in a memory, and predicts the next replacement timing of the consumable. Further, the service information notification system acquires user data including the degree of necessity for the service information of the user associated with the vehicle and stores the user data in the memory. The service information notification system notifies service information to a predetermined destination associated with a user whose necessity exceeds a predetermined value in accordance with the predicted next exchange timing.

The communication unit 21 transmits and receives radio signals to and from an access point (radio base station, etc.) in the vicinity of the vehicle 20, and executes communication with the service information notification system 100 and the like via the access point.

The communication unit 21 may be provided in the vehicle 20 as a communication module, or may be realized by using the terminal device 35 used by the user 30. When realized by using the terminal device 35, the use of a mobile communication network such as 4G (LTE) is typically mentioned. In addition, other wireless communication methods (wireless LAN, etc.) may be used.

The wear state measuring unit 23 measures the wear state of various consumables used in the vehicle 20. In this embodiment, engine oil, a battery, and a tire are targeted as consumables.

However, the consumables are not limited to such examples, and consumables that are replaced relatively frequently include air conditioner filters, wiper blades, brake pads, engine oil filters, and the like. In a broad sense, it also includes fan belts, timing belts, spark plugs, shock absorbers, clutches, water pumps and the like.

The consumption state measuring unit 23 measures the internal resistance of the battery (State of Health) as an index of the consumption state (which may be referred to as a deterioration state) of the battery. The type of battery used in the vehicle 20 is not particularly limited. Specifically, a type that can be replenished with battery fluid or a type that cannot be replenished (maintenance-free), and a dry battery are included. It also includes auxiliary batteries for hybrid vehicles.

The wear state measuring unit 23 measures the slip ratio obtained from the rotation difference between the drive wheel and the driven wheel of the vehicle 20 as an index of the wear state (which may be called a wear state) of the tire. The specific measurement methods for HC, SoH and the slip ratio will be described later.

The wear state measurement unit 23 transmits the wear state data including the identification information of the vehicle 20 to the service information notification system 100 via the communication unit 21. The vehicle 20 identification information may be a chassis number or a vehicle registration number (license plate), but other information may be used as long as the vehicle 20 can be uniquely identified.

Further, when the consumables are replaced in the vehicle 20 and the replacement timing of the consumables is reset, the wear state measuring unit 23 transmits the replaced data indicating that the consumables have been replaced via the communication unit 21. Can be transmitted to the service information notification system 100.

The vehicle usage status acquisition unit 24 acquires the usage status of the vehicle 20. Specifically, the vehicle usage status acquisition unit 24 has acceleration G / deceleration G, angular velocity (yaw rate), steering amount, throttle opening, and brake based on a signal provided from a sensor group provided in the vehicle 20. Information indicating how the vehicle 20 is used, such as pressure, is acquired.

Further, the vehicle usage status acquisition unit 24 can calculate (estimate) the load weight of the vehicle 20 using the sensor group and acquire the number of times of charging / discharging of the battery mounted on the vehicle 20.

In particular, in the present embodiment, the infotainment system 25 can display the service information transmitted from the service information notification system 100.
(2) Service information notification system 100

FIG. 3 is a functional block configuration diagram of the service information notification system 100. As shown in FIG. 3, the service information notification system 100 includes a consumption state data acquisition unit 110, a user data acquisition unit 120, a related data acquisition unit 130, an exchange timing prediction unit 140, and a notification unit 150.

The service information notification system 100 is realized by executing a program (software) on a general-purpose server computer including a processor, a memory, an input device, a display, and a communication interface (communication IF). As described above, a part (or all) of the service information notification system 100 may be provided on the network cloud 60.

The wear state data acquisition unit 110 acquires wear state data (HC, SoH, and slip rate) indicating the wear state of the consumables from the vehicle 20. Further, the wear state data acquisition unit 110 holds the acquired wear state data in the memory.

Further, the consumable state data acquisition unit 110 can acquire the exchanged data indicating that the consumables have been exchanged from the vehicle 20 in the vehicle 20, and store the acquired exchanged data in the memory. The consumable state data acquisition unit 110 may acquire the exchanged data via the customer DB 200.

The user data acquisition unit 120 acquires user data which is data related to the user 30 associated with the vehicle 20. In the present embodiment, the user data acquisition unit 120 acquires the user data of the user 30 from the customer DB 200. The user data acquisition unit 120 may acquire some user data from the service on the network cloud 60.

In particular, the user data acquisition unit 120 acquires user data including the degree of necessity for the service information of the user 30, and stores the acquired user data in the memory. The "necessity for service information" means how much the user 30 needs the service information that recommends the replacement of consumables.

Further, in the present embodiment, the necessity is the sensitivity to the replacement cost (total price including the work wage) of the consumables of the user 30 (hereinafter, referred to as the price sensitivity in the present embodiment) and the vehicle 20. Includes royalties to manufacturers or dealers. The specific content of the necessity will be described later.

The user data acquired by the user data acquisition unit 120 includes the identification information of the user 30 associated with the vehicle 20 and the necessity thereof. The identification information of the user 30 typically includes an e-mail address that can uniquely identify the user 30. However, any information other than the e-mail address may be used as long as the information can uniquely identify the user 30 (actually, the terminal device 35 used by the user 30 or the like).

The related data acquisition unit 130 acquires data indicating at least one of the grade of consumables currently used in the vehicle 20 and the usage status of the vehicle 20 (hereinafter referred to as related data), and holds the acquired related data in the memory. Let me.

Specifically, the related data acquisition unit 130 acquires data indicating the grade of the consumable from the customer DB 200.

Here, "grade" is defined as including the type and grade of consumables. In the case of engine oil, the grade includes the presence or absence of additives separate from the engine oil, and in the case of tires, the grade includes the type of tire (summer tire, winter (studless) tire, low rolling resistance ( RR) tire) and tire size (tread width, flatness and tire diameter) are included.

Further, the related data acquisition unit 130 acquires data indicating the usage status of the vehicle 20 from the vehicle 20 or the network cloud 60.

Here, the "usage status" refers to information on the area in which the vehicle 20 travels (climate (temperature, humidity, amount of solar radiation), terrain, road composition, etc.) and information on how the vehicle 20 is used (acceleration G / deceleration). It is defined as including G, load weight, steering amount, battery charge / discharge frequency, etc.).

The vehicle 20 (or network cloud 60) has a function of directly or indirectly detecting the information.

The replacement timing prediction unit 140 predicts the next replacement timing of the consumables based on the acquired consumable state data. Specifically, the replacement timing prediction unit 140 predicts the next replacement timing of the consumables by using a deterioration model (see FIG. 8) for each type of consumables. The method of predicting the next replacement timing for each consumable item (engine oil, battery and tire) according to this embodiment will be further described later.

Further, the replacement timing prediction unit 140 uses the next replacement timing predicted in this way as the standard replacement timing which is the standard of the next replacement timing of the consumable. That is, the replacement timing prediction unit 140 predicts the standard replacement timing, which is the standard of the next replacement timing of the consumable, based on the acquired wear state data.

Further, the replacement timing prediction unit 140 corrects the standard replacement timing by using the related data (consumable grade and usage status of the vehicle 20) acquired by the related data acquisition unit 130.

Specifically, the replacement timing prediction unit 140 sets the next replacement timing of consumables whose grade exceeds a predetermined value, that is, consumables whose grade is high and whose lifetime is assumed to be longer than the standard, to be higher than the standard replacement timing. Can be delayed.

On the contrary, the replacement timing prediction unit 140 can advance the next replacement timing of consumables whose grade is low and whose lifetime is assumed to be shorter than the standard replacement timing to be earlier than the standard replacement timing.

Similarly, the replacement timing prediction unit 140 sets the next replacement timing of the consumable as the standard when the usage status exceeds a predetermined condition, that is, when the usage status of the vehicle 20 is severe and it is considered that the consumption is likely to progress. It can be earlier than the replacement timing.

On the contrary, when the usage status of the vehicle 20 is mild and the consumption is considered to be slow, the replacement timing prediction unit 140 can delay the next replacement timing of the consumables from the standard replacement timing.

The notification unit 150 notifies the service information to a predetermined destination (terminal device 35 in this embodiment) associated with the user 30. Specifically, the notification unit 150 notifies the service information to the user whose necessity of the above-mentioned service information exceeds a predetermined value according to the next replacement timing of the consumables predicted by the replacement timing prediction unit 140. do.

More specifically, the notification unit 150 can notify the service information to the users belonging to a predetermined class based on the combination of the high price sensitivity and the high loyalty.

The notification unit 150 notifies the service information within a predetermined time (for example, one week to one month) before and after the predicted next exchange timing. When the infotainment system 25 provided in the vehicle 20 is associated as a predetermined destination, the notification unit 150 notifies the infotainment system 25 of the service information.

In the present embodiment, the service information is composed of data indicating the names of consumables for which replacement is recommended and the degree of consumption (degree of deterioration) of the consumables. However, data indicating the degree of consumption of the consumables is not always essential.

Further, the service information may include the exchange deadline of the consumables or the information of the coupon for discounting the price of the consumables and the like.

Further, in order to encourage the dealer 50 to exchange consumables, the notification unit 150 exchanges the above-mentioned service information with a predetermined destination (terminal device) associated with a user whose necessity is equal to or less than a predetermined value. The service information can be notified at a timing earlier than the standard exchange timing predicted by the timing prediction unit 140.

The notification unit 150 cancels the notification of the service information when the exchanged data indicating that the consumables have been exchanged is acquired by the consumption state data acquisition unit 110. That is, the notification unit 150 does not notify the service information when the exchanged data is acquired even within a predetermined time before and after the predicted next exchange timing.

(Operation of service information notification system)

Next, the operation of the service information notification system 100 will be described. Specifically, the operation of notifying service information by the vehicle management network 10 including the service information notification system 100 and the operation of correcting the next replacement timing of consumables will be described.
(1) Notification of service information

FIG. 4 shows a service information notification flow by the vehicle management network 10 including the service information notification system 100.

As shown in FIG. 4, the vehicle 20 measures the consumable state of consumables (S10). In the present embodiment, the vehicle 20 measures the exhausted state of the engine oil, the battery, and the tire. The specific method for measuring the consumable state of each consumable item is as described above (see the description of the consumable state measuring unit 23 in FIG. 2). The specific measurement method of HC, SoH and slip ratio including the next replacement timing (standard replacement timing) will be described later.

The vehicle 20 transmits the consumption state data indicating the consumption state of the consumables to the service information notification system 100 based on the measurement result of the consumption state (S20). The consumption state data includes identification information of the vehicle 20.

Further, the vehicle 20 may transmit data (related data) indicating the usage status of the vehicle 20, such as acceleration G / deceleration G generated by the vehicle 20, and the weight loaded on the vehicle 20, to the service information notification system 100.

The service information notification system 100 receives the consumption state data (S30). The service information notification system 100 predicts the next replacement timing of consumables based on the received consumable state data (S35).

Here, FIG. 8 shows an example of a deterioration model used for predicting the next replacement timing of consumables. The horizontal axis of FIG. 8 shows time, and the vertical axis shows the degree of deterioration of consumables.

The service information notification system 100 specifies the current value in the deterioration model based on the value of the wear state data repeatedly transmitted from the vehicle 20. The "deterioration model" may be a model defined by default for each consumable item, or may be a model that is learned using a large amount of acquired consumption state data and is appropriately updated.

The service information notification system 100 holds the degree of deterioration associated with the value of the predetermined consumption state data as the recommended replacement level of the consumables. Based on the deterioration model, the service information notification system 100 predicts the timing at which the replacement recommended level is reached as the next replacement timing, specifically, the standard replacement timing ts.

The service information notification system 100 sets the standard replacement timing ts to replacement timing t1 (when accelerating) or replacement timing t2 (when the user 30 is required for service information, the grade of consumables, or the usage status of the vehicle 20). If you want to delay it), you can correct it.

The service information notification system 100 determines whether or not the consumables need to be replaced based on the predicted next replacement timing (S40).

Specifically, the service information notification system 100 determines that the consumables need to be replaced if the current time and the predicted time of the next replacement timing are within a predetermined time.

When the service information notification system 100 determines that the consumables need to be replaced, the service information notification system 100 requests user data from the customer DB 200 (S50).

Specifically, the service information notification system 100 transmits the identification information of the vehicle 20 to the customer DB 200, and requests the user data of the user 30 associated with the identification information of the vehicle 20.

The customer DB 200 transmits the user data of the user 30 to the service information notification system 100 in response to a request from the service information notification system 100 (S60). Here, FIG. 9A shows a configuration example of a database stored in the customer DB 200.

In the example shown in FIG. 9A, the database has "vehicle identification information" (for example, chassis number), "user identification information" (for example, e-mail address), "visit date", "work content", and "price sensitivity". Includes items such as "Tivity (Price Sens.)", "Royalty" and "Service Information Necessity Class".

The customer DB 200 transmits the user data of the user 30 to the service information notification system 100 based on the contents of the database shown in FIG. 9A.

9B and 9C show an example of the data structure of user data. As shown in FIG. 9B, the customer DB 200 can transmit user data including "user identification information" (aaaa @ xxx) and "service information necessity class" (1). Alternatively, as shown in FIG. 9C, the customer DB 200 transmits user data including "user identification information" (aaaa @ xxx), "price sensitivity" (Low), and "royalty" (High). You can also do it.

The service information notification system 100 receives the user data (S70). The service information notification system 100 determines whether or not to notify the service information to the user 30 based on the received user data (S80).

Specifically, in the service information notification system 100, the value of the "service information necessity class" included in the user data shown in FIG. 9B matches a predetermined value (for example, the service information necessity class = 1). If so, it is determined to notify the service information.

Alternatively, the service information notification system 100 has a "service information necessity class" based on a combination of the high "price sensitivity" and the high "royalty" included in the user data shown in FIG. 9C. May be determined.

Which of the data structures shown in FIGS. 9B and 9C is used may be determined according to the number of stages of price sensitivity and royalties, the range of classes for which the degree of necessity is to be set, and the like.

FIG. 10 shows a configuration example of a service information necessity class. As shown in FIG. 10, the service information necessity class is composed of a combination of price sensitivity for consumables and royalties for the manufacturer or dealer of the vehicle 20.

In the example shown in FIG. 10, both price sensitivity and royalty are set in three stages (Low (L), Mid (M), High (H)). For example, the combination of price sensitivity = Low and royalty = High is classified as necessity class = 1 (class with the highest exchangeability at the dealer 50). Hereinafter, they are similarly classified into necessity classes 2 to 9. For example, the combination of price sensitivity = High and royalty = Low is classified as necessity class = 9 (indicated by a black circle in FIG. 10, the class with the lowest exchangeability at the dealer 50).

When the service information notification system 100 determines that the service information is to be notified, the service information notification system 100 is directed to a terminal device 35 capable of receiving an e-mail addressed to a predetermined destination associated with the user 30, specifically, the e-mail address of the user 30. Service information is transmitted (S90).

The service information notification system 100 may send an e-mail that directly displays the service information, or may send a link to a specific site that displays the details of the service information.

Alternatively, the service information notification system 100 may transmit service information to a dedicated application installed in the terminal device 35. The service information may include information indicating the degree of consumption (degree of deterioration) of consumables.

Further, when the service information notification system 100 acquires the exchanged data indicating that the consumables have been exchanged from the vehicle 20 or the customer DB 200, even if it is determined in step S40 that the consumables need to be exchanged. , Stop sending service information.

Further, in this operation example, the service information notification system 100 also transmits the same service information to the terminal device 55 deployed in the dealer 50. The service information may be a copy of the service information transmitted to the terminal device 35, or may be an issuance notification indicating that the service information has been issued to the user 30.

The terminal device 55 receives the service information (or issuance notification) (S100). Similarly, the terminal device 35 also receives the service information (S110).

11A to 11C show an example of a data structure of service information. As shown in FIG. 11A, the service information notification system 100 includes name data (engine oil) of consumables for which replacement is recommended and consumption degree data (level 2) indicating the degree of consumption (deterioration degree) of the consumables. Service information including can be sent.

Further, as shown in FIG. 11B, the service information notification system 100 can transmit service information including name data of a plurality of consumables and consumption degree data. In this case, it is not always recommended to replace some consumables (here, the battery). That is, when replacement of a specific consumable is recommended, the user 30 (specifically, the terminal device 35 or the infotainment system 25) may be notified of the degree of consumption of other consumables. ..

Further, the service information notification system 100 includes a coupon for discounting, freeing, or giving benefits to the price of the consumable or other related consumables or services (such as wages), as shown in FIG. 11C. Service information can be sent.

Further, the service information may include a replacement deadline for the consumables (“2018/03/31” in FIG. 11C). The exchange deadline may be determined based on the degree of consumption of the consumables, or may be associated with the applicable deadline of the coupon.

FIG. 12 shows an example of service information displayed on the terminal device 35. As shown in FIG. 12, the service information includes a message recommending the replacement of consumables (engine oil). Further, in the example shown in FIG. 12, the service information also has the function of a coupon that discounts the price (10% off). The coupon function is not essential.

In addition, the service information includes information indicating the degree of consumption (deterioration degree) of consumables (“the deterioration level of engine oil is“ 2 ””).

After that, when the vehicle 20 is stored in the dealer 50 and the replacement of the consumables (engine oil) is completed, the operator of the dealer 50 resets and replaces the previous engine oil replacement timing held by the vehicle 20. The record (replacement date, grade, etc.) is input using the terminal device 55 (S120). The input exchange record is reflected in the customer DB 200.

Further, the operator of the dealer 50 may input the attributes of the user 30, specifically, price sensitivity and loyalty. Alternatively, the attribute of the user 30 may be automatically or semi-automatically input from the receipt date, the grade of the selected consumable item, the past exchange record, and the like.

Further, the service information notification system 100 may advance the standard exchange timing ts to the exchange timing t1 for the user who visits the dealer 50 infrequently.

Further, when the vehicle 20 is inspected by the dealer 50, the usage of the vehicle is ranked based on the consumption state of consumables (for example, the remaining amount of brake pads and tire grooves), and the usage status is assumed to be severe for users. On the other hand, the standard exchange timing ts may be advanced to the exchange timing t1.

Further, the service information notification system 100 may transmit service information (or issuance notification) not only to the dealer 50 but also to other dealers existing around the dealer 50.
(2) Correction operation of next replacement timing

Next, the correction operation of the next replacement timing of the consumables will be described with reference to FIGS. 5 to 7. Specifically, the correction operation of the next replacement timing of the engine oil, the battery and the tire will be described. 5 to 7 show the correction operation flow of the next replacement timing of the engine oil, the battery, and the tire, respectively.

Note that the operation flows shown in FIGS. 5 to 7 are all executed as subflows of the next exchange timing prediction process (S35) shown in FIG. 4, and are not necessarily essential.
(2.1) Engine oil

FIG. 5 shows a correction operation flow of the next replacement timing of the engine oil. As shown in FIG. 5, the service information notification system 100 acquires the amount of hydrocarbon (HC) generated in the blow-by gas (S210). The vehicle 20 includes a detector that detects HC contained in blow-by gas in the crankcase of the engine.

Regardless of the type of tire, the standard replacement timing ts may be advanced to the replacement timing t1.

According to the above-described embodiment, the following effects can be obtained.

According to the service information notification system 100, the next replacement timing of the consumable item is predicted based on the consumption state data repeatedly acquired from the vehicle 20. Further, the service information is notified to a predetermined destination (for example, the terminal device 35) associated with the user whose necessity for the service information exceeds the predetermined value according to the predicted next exchange timing. ..

Therefore, the next replacement timing can be predicted without using the previous replacement timing of the consumable. In addition, the service information can be selectively notified to the user who has a high need for the service information. This makes it possible to recommend individual users to replace consumables at a more appropriate timing. As a result, such notification of service information contributes to the timely replacement of consumables, and may contribute to maintaining the good condition of the vehicle 20 and improving the safety.

Further, since the notification of the service information is suppressed to the user who does not need the service information, it is possible to prevent the waste of the resources of the system and the communication network. In addition, it is possible to prevent the user from feeling that the service information is annoying.

Further, according to the service information notification system 100, it is possible to recommend the replacement of consumables to individual users at a more appropriate timing, so that the user who receives the service information has an opportunity to replace the consumables at the dealer 50. Can be increased.

In the present embodiment, the service information notification system 100 predicts the standard replacement timing ts based on the consumption status data acquired from the vehicle 20, and uses the related data (consumable grade and usage status of the vehicle 20) as a standard. The exchange timing ts can be corrected to the exchange timing t1 (when advancing) or the exchange timing t2 (when delaying) (see FIG. 8). This makes it possible to set a more accurate next replacement timing of the consumable item according to the actual consumable item consumption state (deterioration state).

In addition, since it is possible to recommend the user to replace the consumables at a more appropriate timing, the appealing power of the replacement of the consumables to the user is enhanced.

In the present embodiment, when the service information notification system 100 acquires the exchanged data indicating that the consumables have been exchanged, the service information notification system 100 cancels the notification of the service information. As a result, it is possible to prevent the service information that is not actually needed from being notified, and the user does not feel annoyed. In addition, this can prevent waste of system and communication network resources.

In the present embodiment, the service information notification system 100 has a predetermined class in which the need for service information is based on a combination of high price sensitivity for consumables of the user and high loyalty to the manufacturer or dealer of the vehicle 20. Service information can be notified to users who belong to. As a result, the users can be segmented in detail, and the service information can be notified to the users belonging to a specific class at a more appropriate timing. In addition, this can prevent the transmission of less effective service information, thus preventing waste of system and communication network resources.

In the present embodiment, the service information notification system 100 can advance the standard exchange timing ts to the exchange timing t1 for the user who visits the dealer 50 infrequently. As a result, the service information can be notified to the user before the consumables are replaced at a place other than the dealer 50 (such as a car accessory store). In addition, this promotes the early replacement of the consumables, which can contribute to maintaining the good condition of the vehicle 20 and improving the safety.

In the present embodiment, the service information notification system 100 can accelerate the standard exchange timing ts to the exchange timing t1 even for a user whose usage is assumed to be severe. This makes it possible to reliably notify service information before consumables exceed the usage limit. Further, as a result, the consumables can be replaced before the usage limit is exceeded, which can contribute to maintaining the good condition of the vehicle 20 and improving the safety.

In the present embodiment, the service information notification system 100 can transmit service information (or issuance notification) not only to the dealer 50 but also to other dealers existing around the dealer 50. As a result, other dealers existing around the dealer 50 can also notify the user of the service information (including the coupon), and the user can compare the services of the plurality of dealers. Further, as a result, service information related to a plurality of dealers can be collectively transmitted, so that waste of system and communication network resources can be prevented.

In the present embodiment, the service information notification system 100 can notify the infotainment system 25 of the service information. This makes it possible to clearly distinguish the service information (coupon) from other than the dealer 50 (car supplies store) and inform the user of the content of the service information. Further, since it is possible to avoid transmission of duplicate service information to the infotainment system 25 and the terminal device 35, it is possible to prevent wasting resources of the system and the communication network.
