And ventilate.

Japanese Unexamined Patent Publication No. 2014-237383

However, the above-mentioned vehicle deodorizing device may not be able to sufficiently deodorize the inside of the vehicle. In this case, it is desirable to request cleaning of the vehicle interior and perform the cleaning. However, if the interior of the vehicle is frequently required to be cleaned, the cleaning work is frequently performed and the efficiency of the cleaning work is lowered. Therefore, it is desired to request cleaning work at an appropriate timing.

The main object of the vehicle cleaning request system of the present invention is to request cleaning work at an appropriate timing.

The vehicle cleaning request system of the present invention has adopted the following means in order to achieve the above-mentioned main object.

The first vehicle cleaning request system of the present invention is
A vehicle cleaning request system including a cleaning requesting unit that requests cleaning of the vehicle interior when the intensity of the odor in the vehicle interior exceeds a threshold value.
The gist is to include a threshold setting unit for setting the threshold value based on the user's evaluation index regarding the odor in the vehicle interior.

In the first vehicle cleaning request system of the present invention, cleaning of the vehicle interior is requested when the intensity of the odor in the vehicle interior exceeds the threshold value. Then, the threshold value is set based on the user's evaluation index regarding the odor in the vehicle interior. As a result, it is possible to request cleaning of the vehicle interior at an appropriate timing based on the user's evaluation index regarding the odor of the vehicle interior.

In the first vehicle cleaning request system of the present invention, the evaluation index of the user is the degree of deodorization in the vehicle interior recognized by the user, and the threshold setting unit is the degree of deodorization in the vehicle interior recognized by the user. When the degree of deodorization is low, the threshold value may be set so as to be lower than when the degree of deodorization is high. In this way, it is possible to request cleaning of the vehicle interior at an appropriate timing according to the degree of deodorization recognized by the user.

Further, the first vehicle cleaning request system of the present invention may include an input receiving unit that receives input of an evaluation index of a user. In this way, it is possible to request cleaning of the vehicle interior using the input evaluation index of the user. In this case, when the user's evaluation of the degree of deodorization is low, the cleaning requesting unit may request cleaning of the vehicle interior with a shorter frequency than when it is high. In this way, it is possible to request cleaning of the vehicle interior at an appropriate frequency according to the user's evaluation.

The second vehicle cleaning request system of the present invention is
A vehicle cleaning request system equipped with a cleaning request unit that requests cleaning of the vehicle interior.
It is provided with a cleaning frequency setting unit that sets the frequency of requesting cleaning of the vehicle interior based on the user's evaluation index regarding the odor of the vehicle interior.
The gist is that the cleaning requesting unit requests cleaning of the vehicle interior at the set frequency.

In the second vehicle cleaning request system of the present invention, the frequency of requesting cleaning of the vehicle interior is set based on the user's evaluation index regarding the odor of the vehicle interior, and the cleaning of the vehicle interior is requested at the set frequency. Then, the vehicle interior is requested to be cleaned at a set frequency. As a result, it is possible to request cleaning of the vehicle interior at an appropriate timing based on the user's evaluation index regarding the odor of the vehicle interior.

FIG. 1 is a configuration diagram showing an outline of the configuration of a car sharing system 10 including a vehicle cleaning request system as an embodiment of the present invention. As shown in the figure, the car sharing system 10 includes a management center 20, a vehicle 30, and a mobile terminal device 50. In the embodiment, the management center 20, the vehicle 30, and the mobile terminal device 50 correspond to the "vehicle cleaning request system".

The management center 20 includes a computer 21, a storage device 22, and a communication device 23. The computer 21 has a CPU, a ROM, a RAM, an input / output port, a communication port, and the like. The storage device 22 is composed of a large-capacity storage medium such as a hard disk or SSD. The storage device 22 stores data and the like regarding individual vehicles parked at each station in which vehicles used by the user are parked. The communication device 23 communicates between the computer 21 and the outside (vehicle 30, mobile terminal device 50, cleaning company 70 that provides a vehicle cleaning service). The computer 21, the storage device 22, and the communication device 23 are connected to each other via a signal line.

The vehicle 30 is configured as an automobile that travels by power from a power source (not shown) such as an engine or a motor, and includes an electronic control unit (hereinafter, referred to as “ECU”) 32 that controls the entire vehicle 30 and a communication device (hereinafter referred to as “ECU”). (Hereinafter referred to as “DCM”) 34 and.

Although not shown, the ECU 32 is configured as a microprocessor centered on a CPU, and in addition to the CPU, a ROM for storing a processing program and a vehicle identification number Vid for each vehicle, and a RAM for temporarily storing data. It has an input / output port and a communication port. Signals from various sensors are input to the ECU 32. The signals input to the ECU 32 include, for example, a detection signal from a sensor for detecting the state of the power source, an odor intensity Sm from the odor intensity sensor 40 for detecting the odor intensity in the vehicle interior cab, and an odor intensity Sm in the vehicle interior. The odor identification sensor value Frg (k) (k = 1 to n) from the odor type discrimination sensor 42 (k) (k = 1 to n, n is a natural number having a value of 2 or more) for discriminating the type of odor in the cab. ) Can be mentioned. Here, "k" corresponds to each odor that can be detected by the odor type discrimination sensor 42 with a numerical value from the value 1 to the value n. In the embodiment, "k" may be referred to as an odor identification value k. The odor type discrimination sensor 42 (k) (k = 1 to n) outputs the corresponding odor intensity as the odor identification sensor value Frg (k) (k = 1 to n). Further, as the signal input to the ECU 32, ID card information from a card reader (not shown) that reads the information of the ID card carried by the user in a non-contact manner can be mentioned. Various control signals are output from the ECU 32 via the output port.

The DCM 34 communicates between the ECU 32 and the outside.

The mobile terminal device 50 is configured as a terminal device that can be carried by a user, and includes a main body (not shown), a display 52, and a communication device. Although not shown, the main body has a CPU, a ROM, a RAM, a storage medium, an input / output port, and a communication port. Various applications and the like are stored in the storage medium of the main body. The display 52 is configured as a touch panel type display device and accepts user input. The communication device communicates between the main body and the outside. Based on the operation of the display 52 of the user, the mobile terminal device 50 transmits instructions for executing various processes such as reservation of use of the vehicle 30 and settlement of the usage fee of the vehicle 30, and various information input by the user via the communication device. Send to the management center 20.

In the car sharing system 10 configured in this way, various processes such as reservation of use of the vehicle 30 parked at the station are executed based on the operation of the display 52 of the mobile terminal device 50 by the user.

The use reservation of the vehicle 30 is made as follows. When the user operates the display 52 of the mobile terminal device 50 to input the reservation request information, the mobile terminal device 50 transmits the reservation request information to the management center 20 via the communication device. The reservation request information includes, for example, the user's identification number (user identification number) Pid, credit card information, the area where the station where the vehicle to be used is parked, the vehicle type of the vehicle to be used, the date and time of use, and the return. The date and time can be mentioned. The computer 21 of the management center 20 determines whether or not it is possible to prepare a vehicle according to the reservation request information received via the communication device 23 based on the data about the vehicle for each station stored in the storage device 22. do. When the computer 21 of the management center 20 can prepare a vehicle according to the reservation request information, the computer 21 stores the reservation request information as reservation information in the storage device 22 and transmits the reservation request information to the reservation target vehicle 30 via the communication device 23 to make a reservation. The completion notification is transmitted to the mobile terminal device 50. When the computer 21 of the management center 20 cannot prepare the vehicle according to the received reservation request information, the computer 21 transmits a reservation non-reservation notification to the mobile terminal device 50 via the communication device 23. The ECU 32 of the vehicle 30 that has received the reservation information stores the reservation information in a RAM (not shown).

In the vehicle 30 reserved in this way, when the information from the non-contact ID card carried by the user is read into a card reader (not shown) mounted on the vehicle 30, the ECU 32 of the vehicle 30 stores the reservation information in the RAM. The user identification number Pid included in the above is compared with the identification number of the ID card to authenticate the user. When the user identification number Pid included in the reservation information and the identification number of the ID card match and the user authentication is successful, the ECU 32 of the vehicle 30 sets the vehicle identification number Vid, the user identification number Pid, and the usage start signal to the DCM34. It is transmitted to the management center 20 via. The computer 21 of the management center 20 that has received the vehicle identification number Vid, the user identification number Pid, and the usage start signal via the communication device 23 sends an unlock permission signal to the vehicle 30 corresponding to the vehicle identification number Vid via the communication device 23. To send. Upon receiving the unlock permission signal via the DCM34, the ECU 32 of the vehicle 30 unlocks the door of the vehicle 30. The vehicle 30 whose door is unlocked is operated in the same manner as a normal vehicle by a user who has obtained a key stored in a storage box in a cabin cab. In this way, the use of the vehicle 30 is started.

The use of the vehicle 30 is stopped as follows. When the key is returned to the storage box in the passenger compartment cab by the user and the information from the non-contact ID card carried by the user is read into a card reader (not shown), the ECU 32 of the vehicle 30 stores it in the RAM. The user is authenticated by comparing the user identification number Pid included in the reservation information and the identification number of the ID card. When the user identification number Pid included in the reservation information and the identification number of the ID card match and the user authentication is successful, the ECU 32 of the vehicle 30 sets the vehicle identification number Vid, the user identification number Pid, and the end-of-use signal to the DCM34. It is transmitted to the management center 20 via. The computer 21 of the management center 20 that has received the usage end signal via the communication device 23 transmits the lock permission signal to the vehicle 30 corresponding to the vehicle identification number Vid via the communication device 23, and also transmits the evaluation request signal to the mobile terminal. It is transmitted to the device 50 to execute a predetermined billing process. The predetermined billing process is performed by settling the billing amount based on the billing plan selected by the user at the time of booking with the credit card included in the booking information. The ECU 32 of the vehicle 30 that has received the lock permission signal via the DCM 34 locks the door.

Next, the operation of the car sharing system 10 thus configured, particularly the operation when requesting the cleaning company 70 to clean the vehicle 30, will be described. FIG. 2 is a flowchart showing an example of a post-use processing routine executed by the ECU 32 of the vehicle 30. This routine is executed after the vehicle 30 transmits the above-mentioned end-of-use signal to the management center 20.

When the post-use processing routine is executed, the ECU 32 of the vehicle 30 uses the vehicle identification number Vid, the odor intensity Sm, the odor identification sensor values Frg (k) (k = 1 to n), the thresholds Smth, and Frgth (k) ( Data required for processing such as k = 1 to n) is input (step S100). As the vehicle identification number Vid, the one stored in the ROM is input. For the odor intensity Sm, the one detected by the odor intensity sensor 40 is input. As the odor identification sensor values Frg (k) (k = 1 to n), those detected by the odor type discrimination sensors 42 (k) (k = 1 to n) are input. The threshold value Smth is a threshold value for determining whether or not the odor in the passenger compartment cab is strong enough to require cleaning. The threshold value Frgth (k) (k = 1 to n) is a threshold value for determining whether or not the user is strong enough to feel the corresponding odor, and is determined for each odor. The threshold values Smth and Frgth (k) (k = 1 to n) are set by a threshold value setting routine described later, which is executed by the computer 21 of the management center 20.

When the data required for the process is input in this way, the process of setting the cleaning request flag Fcl is executed (steps S110 to S130). The cleaning request flag Fcl is a flag indicating whether or not cleaning of the vehicle 30 is requested.

In the setting of the cleaning request flag Fcl, first, it is determined whether or not the odor intensity Sm is larger than the threshold value Smth (step S110). When the odor intensity Sm is equal to or less than the threshold value Smth, the cleaning request flag Fcl is set to a value 0 (step S120), and when the odor intensity Sm exceeds the threshold value Smth, the cleaning request flag Fcl is set to a value 1 (step S130). ).

Subsequently, the odor type flag Ffrg (k) (k = 1 to n) is set (steps S140 to S190). The odor type flag Ffrg (k) (k = 1 to n) is a flag indicating whether or not the odor that can be detected by the odor type discrimination sensor 42 (k) (k = 1 to n) is strong enough to be recognized by the user. Is.

In the setting of the odor type flag Ffrg (k) (k = 1 to n), first, the odor identification value k indicating the type of odor that can be detected by the odor type discrimination sensor 42 (k) (k = 1 to n) is set. Set to a value of 1 (step S140). Subsequently, it is determined whether or not the identification sensor value Frg (k) is larger than the corresponding threshold value Frgth (k) (step S150). When the identification sensor value Frg (k) is equal to or less than the threshold value Frgth (k), the odor type flag Ffrg (k) is set to a value 0 (step S160), and the identification sensor value Frg (k) sets the threshold value Frgth (k). When it exceeds, the value 1 is set in the odor type flag Ffrg (k) (step S170). Then, the value 1 is added to the odor identification value k (step S180), and it is determined whether or not the added odor identification value k is larger than the value n (step S190). When the odor identification value k is equal to or less than the value n, the process returns to step S150, and steps S150 to S190 are repeated until the odor identification value k exceeds the value n.

When step S150 is executed for the first time, a value 1 is set for the odor identification value k. Therefore, step S150 is a process of determining whether or not the identification sensor value Frg (1) is larger than the threshold value Frgth (1). Then, step S160 is a process of setting a value 0 in the odor type flag Ffrg (1). Step S170 is a process of setting a value 1 in the type flag Ffrg (1). When the value 1 is added to the odor identification value k in step S180 and the value 2 is set to the odor identification value k, the value n is now a natural number having a value of 2 or more, so the process returns to step S150. At this time, step S150 is a process of determining whether or not the identification sensor value Frg (2) is larger than the threshold value Frgth (2). Then, step S160 is a process of setting a value 0 in the odor type flag Ffrg (2). Step S170 is a process of setting the value 1 in the odor type flag Ffrg (2). By repeating steps S150 to S190 in this way, the intensity of the odor detected by the odor type discrimination sensor 42 (k) (k = 1 to n) is sequentially checked. Then, a value 0 is set for the odor type flag Ffrg (k) corresponding to the odor of the intensity that the user does not feel in the cabin cab, and the odor corresponds to the intensity that the user feels in the cabin cab. A value of 1 is set for the odor type flag Ffrg (k).

When the odor identification value k exceeds the value n in step S190, that is, when the intensity of each odor detected by the odor type discrimination sensor 42 (k) (k = 1 to n) has been examined, the vehicle identification number The Vid, the cleaning request flag Fcl, and the odor type flag Ffrg (k) are transmitted to the management center 20 via the DCM34 (step S195), and this routine is terminated. When the management center 20 receives the vehicle identification number Vid, the cleaning request flag Fcl, and the odor type flag Ffrg (k) via the communication device 23, the management center 20 receives the cleaning request flag Fcl and the odor type flag Ffrg (k) in the vehicle identification number Vid. Is input to the computer 21. The computer 21 associates the cleaning request flag Fcl with the odor type flag Ffrg (k) with the vehicle identification number Vid and stores it in the storage device 22. Then, the computer 21 executes the processing routine illustrated in FIG. 3 using the vehicle identification number Vid and the cleaning request flag Fcl, and executes the cleaning request flag Fcl, the odor type flag Ffrg (k), and the user identification number. Using the Pid, the deodorant evaluation value SR (Pid), and the preference evaluation value Fr (Pid), the threshold setting routine illustrated in FIG. 4 is executed.

FIG. 3 is a flowchart showing an example of a processing routine executed by the computer 21 of the management center 20. This processing routine is executed when the vehicle identification number Vid and the cleaning request flag Fcl are input to the computer 21.

When the processing routine is executed, the CPU (not shown) of the computer 21 of the management center 20 executes a process of inputting the vehicle identification number Vid and the cleaning request flag Fcl from the storage device 22 (step S200). Then, it is determined whether or not the cleaning request flag Fcl has a value of 1 (step S210). When the cleaning request flag Fcl is a value 0, it is determined that cleaning inside the cabin cab of the vehicle 30 is not requested, the processing routine is terminated, and when the cleaning request flag Fcl is a value 1, the cabin of the vehicle 30 is terminated. It is determined that cleaning of the inside of the cab is required, and the vehicle identification number Vid and the cleaning request signal are transmitted to the cleaning company 70 (step S220). The cleaning company 70, which has received the vehicle identification number Vid and the cleaning request signal, executes the cleaning work of the vehicle 30 corresponding to the vehicle identification number Vid. By such a process, when the odor in the cabin cab of the vehicle 30 is strong enough to require cleaning, the vehicle 30 is cleaned.

FIG. 4 is a flowchart showing an example of a threshold setting routine executed by the computer 21 of the management center 20. This threshold value setting routine is executed when the evaluation setting routine of FIG. 5 is executed and the user identification number Pid, the deodorant evaluation value SR (Pid), and the preference evaluation value Fr (Pid) are received from the mobile terminal device 50. NS. Here, for convenience of explanation, the evaluation setting routine of FIG. 5 will be described before the threshold value setting routine of FIG. 4 is described.

FIG. 5 is a flowchart showing an example of an evaluation setting routine executed by the main body of the mobile terminal device 50. When the evaluation setting routine is executed, the mobile terminal device 50 receives the input of the user identification number Pid, the deodorant evaluation value SR, and the preference evaluation value Fr (step S300), and waits until the input from the user is completed. (Step S310). The input from the user is accepted by displaying the screen for accepting the input of the user identification number Pid, the deodorant evaluation value SR, and the preference evaluation value Fr on the display 52 of the mobile terminal device 50. The deodorant evaluation value SR is the degree of deodorization in the passenger compartment cab of the vehicle 30 by the user, with a value of 5 for "no odor", a value of 4 for "no odor", a value of 3 for "not anxious", and "a value of 3". It is a value evaluated by quantifying "smell" as a value 2 and "very smell" as a value 1. The preference evaluation value Fr is a value of 5 for the user's preference for the odor in the cabin cab of the vehicle 30, a value of 4 for "like", a value of 3 for "normal", a value of 2 for "dislike", and "dislike". It is a value evaluated by quantifying "I hate it very much" as a value of 1.

When the user's input is completed, the input user identification number Pid, deodorant evaluation value SR, and preference evaluation value Fr are transmitted to the management center 20 using a communication device (not shown) (step S320), and the evaluation setting routine is performed. finish.

Next, the threshold value setting routine of FIG. 4 will be described. When the threshold setting routine is executed, the CPU (not shown) of the computer 21 of the management center 20 uses the vehicle identification number Vid, the odor type flag Ffrg (k) (k = 1 to n), the user identification number Pid, and the user. A process of inputting the deodorant evaluation value SR and the preference evaluation value Fr of the user corresponding to the identification number Pid is executed (step S400). The vehicle identification number Vid is input from the vehicle 30. The odor type flag Ffrg (k) (k = 1 to n) is the odor type flag Ffrg (k) (k = 1 to 1) corresponding to the vehicle identification number Vid from various data stored in the storage device 22 of the management center 20. n) is derived and input. The user identification number Pid, the deodorant evaluation value SR, and the preference evaluation value Fr are input to those transmitted by the evaluation setting routine of FIG. 5 executed by the mobile terminal device 50.

Next, the odor identification value kcab corresponding to the odor in the passenger compartment cab of the vehicle 30 is specified by using the odor type flag Ffrg (k) (k = 1 to n) (step S410). The odor identification value kcab is specified as "k" corresponding to the flag having a value of 1 among the odor type flags Ffrg (k) (k = 1 to n).

Next, for the vehicle 30 corresponding to the vehicle identification number Vid, the evaluation number n, which is the number of users who have evaluated the deodorant evaluation and the odor preference so far, is calculated (step S420). The evaluation number n is calculated by adding the value 1 to the evaluation number n (previous n) when the present routine was executed last time.

Subsequently, using the following equation (1), the average deodorant evaluation value SRav as the average value of the deodorant evaluation value SR in the vehicle 30 corresponding to the vehicle identification number Vid is calculated (step S430). In the equation (1), the "previous SRav" is the average deodorant evaluation value SRav set when the present routine was executed last time. The average deodorant evaluation value SRav is an index showing the degree of deodorization of the vehicle 30, and when the user feels that the degree of deodorization of the vehicle 30 is high, it is compared with the case where the degree of deodorization is low. And it becomes a high value.

SRav = (previous SRav + SR-3) / n

Next, using the following equation (2), the odor preference evaluation integrated value FRct (kcab) corresponding to the odor identification value kcab in the vehicle 30 corresponding to the vehicle identification number Vid is set (step S440). In the formula (2), the "previous FRct (kcab)" is the preference evaluation integrated value FRct (kcab) set when the present routine was executed last time. That is, the preference evaluation integrated value FRct (kcab) is an index of how much the user who has used the vehicle 30 has preferred the odor corresponding to the odor identification value kcab, and the user who has used the vehicle 30 has the odor identification value. When the odor corresponding to k is liked, it becomes larger than when it is not liked.

FRct (kcab) = Last time FRct (kcab) + Fr-3

Next, the correlation Cr between the cleaning request flag Fcl and the odor type flag Ffrg (k) (k = 1 to n) is examined (step S450). The correlation between the cleaning request flag Fcl and the odor type flag Ffrg (k) (k = 1 to n) is, for example, for which odor identification value k the cleaning request flag Fcl is likely to have a value of 1.

When the average deodorant evaluation value SRav and the taste evaluation integrated value FRct (k) (k = 1 to n) are set in this way, the threshold value Smth is set using the average deodorant evaluation value SRav, and the preference evaluation integrated value FRct ( k) The threshold value Frgth is set using (k = 1 to n) and the correlation Cr (step S460). The threshold value Smth is set so that when the average deodorant evaluation value SRav is small, the average deodorant evaluation value SRav is smaller than when it is large. The threshold value Frgth (k) is set so that when the taste evaluation integrated value FRct (k) is small, it is smaller than when it is large, and for the correlation Cr, it is set to be smaller. , When the cleaning request flag Fcl is likely to be a value 1, it is set to be smaller than when it is difficult to be a value 1.

The threshold values Smth and Frgth (k) (k = 1 to n) set in this way are transmitted to the vehicle 30 having the vehicle identification number Vid (step S460), and this routine is terminated. The vehicle 30 having the vehicle identification number Vid that has received the threshold values Smth and Frgth (k) (k = 1 to n) uses the threshold values Smth and Frgth (k) (k = 1 to n) after the end of use of FIG. Execute the processing routine.

The threshold value Smth is set to be smaller when the average deodorant evaluation value SRav is smaller than when it is large, that is, when the user feels that the degree of deodorization of the vehicle 30 is low, it is compared to when it is felt to be high. Is set to be smaller. Therefore, when the user feels that the degree of deodorization of the vehicle 30 is low in step S110 of the post-use processing routine of FIG. 2, the odor intensity Sm is larger than the threshold value Smth as compared with the case where the user feels that the degree of deodorization is high. The frequency of determination increases, the frequency of setting the cleaning request flag Fcl to the value 1 increases in step S130, step S220 of the processing routine illustrated in FIG. 3 is executed, and the cleaning request signal is transmitted to the cleaning company 70. Will be done more often. When the user feels that the degree of deodorization of the vehicle 30 is low, it is considered that the need for cleaning is higher than when the user feels that the degree of deodorization is high. Therefore, the cleaning work is performed at an appropriate frequency, that is, at an appropriate timing. Can be requested.

The threshold value Frgth (k) is preferred so that when the preference evaluation integrated value FRct (kcab) is small, it becomes smaller than when it is large, that is, when the user does not like the odor corresponding to the odor identification value kcab. It is set to be smaller than sometimes. Therefore, in step S150 of the post-use processing routine of FIG. 2, when the user does not like the odor corresponding to the odor identification value kcab, the odor identification sensor value Frg (k) is a threshold value as compared with the case where the user does. When it is determined that the value is larger than Frgth (k) more frequently, the odor type flag Ffrg (k) is set to the value 1 more frequently in step S170, and the user prefers the odor corresponding to the odor identification value k. It becomes easier to judge.

Further, as the correlation Cr, when there is a correlation between the cleaning request flag Fcl and the odor type flag Ffrg (kcab) that the cleaning request flag Fcl tends to have a value of 1, the threshold value Frgth (k) is compared with the case where there is no such correlation. ) May be reduced, or the threshold value Frgth (k) used in step S150 of the same routine may be lowered. By doing so, the odor type flag Ffrg (k) is frequently set to the value 1 for a specific odor (odor identification value k), and it is determined that the user prefers the odor corresponding to the odor identification value k. It will be easier.

According to the car sharing system 10 including the vehicle cleaning request system of the above-described embodiment, the threshold value Smth is set based on the deodorant evaluation value SR which is the user's evaluation index regarding the odor in the vehicle interior cab. Cleaning work can be requested at an appropriate timing.

In the car sharing system 10 including the vehicle cleaning request system of the embodiment, the processing routines illustrated in FIGS. 2 to 4 are executed. However, instead of the processing routines of FIGS. 2 to 4, the cleaning interval setting routine of FIG. 6 executed by the computer 21 of the management center 20 may be executed. The cleaning interval setting routine of FIG. 6 executes the same processing as steps S410 to S420 of the threshold value setting routine of FIG. 4 between steps S500 and S550. Therefore, the same processing as the threshold value setting routine of FIG. 4 is designated by the same reference numerals, and detailed description thereof will be omitted.

The cleaning interval setting routine of FIG. 6 is executed by the computer 21 of the management center 20 when the management center 20 receives the usage end signal from the vehicle 30. When the cleaning interval setting routine is executed, the CPU of the computer 21 performs the same processing as step S400 of the threshold value setting routine of FIG. 4 to obtain the odor type flag Ffrg (k) (k = 1 to n) and the user identification number. A process of inputting the Pid and the deodorant evaluation value SR and the preference evaluation value Fr of the user corresponding to the user identification number Pid is executed (step S500). Then, steps S410 to S440 are executed.

Next, it is determined whether or not the average deodorant evaluation value SRav is less than the threshold value SRbth (step S550). The threshold value SRbth is a threshold value for determining whether or not the user feels an odor to the extent that the vehicle 30 needs to be cleaned.

When the average deodorant evaluation value SRav is less than the threshold SRbth in step S550, the user strongly feels that the vehicle 30 smells, and determines that the interval for cleaning the vehicle 30 should be shortened, and the previous vehicle 30 The cleaning interval SRit, which is the interval from the cleaning work to the next cleaning work, is the value obtained by subtracting the value 1 from the cleaning interval SRit (previous SRit) when this routine was executed last time for the vehicle 30 (previous SRit). = Set to SRit-1) last time, and transmit the set cleaning interval SRit to the cleaning company 70 (step S560). The cleaning company 70 cleans the vehicle 30 at the received cleaning interval SRit.

When the average deodorant evaluation value SRav is equal to or higher than the threshold value SRbth in step S550, it is determined that the user does not feel that the vehicle 30 smells so strongly, and subsequently, whether or not the average deodorant evaluation value SRav is less than the threshold value SRgth. (Step S570). The threshold value SRgth is a threshold value for determining whether or not the user feels an odor to the extent that cleaning of the vehicle 30 is considered unnecessary. The threshold SRgth is set to a value larger than the threshold SRbth.

When the average deodorant evaluation value SRav exceeds the threshold SRgth in step S570, it is determined that the interval for cleaning the vehicle 30 may be lengthened because the user does not recognize that the vehicle 30 smells. , The cleaning interval SRit is set to the value obtained by adding the value 1 to the cleaning interval SRit (previous SRit) when this routine was executed last time for the vehicle 30 (= previous SRit + 1), and the set cleaning interval SRit is set to the cleaning company. It is transmitted to 70 (step S580). The cleaning company 70 cleans the vehicle 30 at the received cleaning interval SRit.

When the average deodorant evaluation value SRav is equal to or less than the threshold value SRgth in step S570, the processes after step S590 are executed without changing the cleaning interval SRit.

Subsequently, the taste evaluation integrated value FRct (kcab) is an odor that can be discriminated by the odor type discrimination sensor 42 (k) (k = 1 to n) and is different from the odor discrimination value kcab. It is determined whether or not the odor corresponding to the above exceeds the preference evaluation integrated value FRct (not_kcab) (step S590). The preference evaluation integrated value FRct (kcab) is set to be larger when the user likes the odor identification value kcab than when he / she does not like it. Therefore, step S590 is a process of determining whether or not the user prefers an odor corresponding to the odor identification value kcab over other odors.

When the preference evaluation integrated value FRct (kcab) is equal to or less than the preference evaluation integrated value FRct (not_kcab) in step S590, the cleaning interval setting routine is terminated.

When the preference evaluation integrated value FRct (kcab) exceeds the preference evaluation integrated value FRct (not_kcab) in step S590, the preference evaluation integrated value FRct (kcab) is set to the maximum value FRMAX and stored in the storage device 22 ( Step S600), the cleaning interval setting routine is terminated. By such processing, the odor most preferred by many users can be stored as the maximum value FRMAX.

The management center 20 can execute various processes using the information of the odor most preferred by the user stored in the storage device 22. Examples of various processes include a process of transmitting information on the odor most preferred by the user to a vehicle in which an odor generator capable of generating a plurality of odors is installed in the passenger compartment cab. In this case, the vehicle may generate an odor included in the received information or an odor close to the odor from the odor generator into the passenger compartment cab.

In the car sharing system 10 including the vehicle cleaning request system of the embodiment, in the threshold value setting routine of FIG. 4, the average deodorant evaluation value SRav is calculated using the deodorant evaluation value SR input by the user, and the calculated average deodorant is calculated. The threshold value Smth is set using the evaluation value SRav. However, the threshold value Smth may be set using the deodorant evaluation value SR. In this case, the threshold value Smth may be set so as to be high when the deodorant evaluation value SR is low.

In the car sharing system 10 including the vehicle cleaning request system of the embodiment, the post-use processing routine illustrated in FIG. 2 is executed by the ECU 32 of the vehicle 30, but the ECU 32 of the vehicle 30 and the computer 21 of the management center 20 Since some or all of the processing may be executed by any one of the main bodies of the mobile terminal device 50, for example, it may be executed by the computer 21 of the management center 20. Similarly, the processing routine of FIG. 3, the threshold value setting routine of FIG. 4, and the threshold value setting routine of FIG. 6 are partially or all of the ECU 32 of the vehicle 30, the computer 21 of the management center 20, and the main body of the mobile terminal device 50. You just have to execute the process of.
