JP2015-41344A JP 2017-182301 A US Pat. No. 6,734,695

  However, with the conventional technologies as described above, it is difficult to appropriately support the prevention of leftovers by the user in a vehicle related to a car sharing service or a vehicle related to a taxi service.

  For example, in a vehicle related to a car sharing service, a state (service end state) in which access to the inside of the vehicle without a penalty is prohibited at the end of the service. In this case, even if the user notices a forgotten item in the vicinity of the vehicle, the user falls into a state where the forgotten item cannot be collected without a penalty (for example, an additional fee).

  In addition, in the vehicle related to the taxi service, since the period from the payment state to the idling state is indefinite, there is a possibility that an object that can be forgotten is left in the passenger compartment or the luggage compartment in the payment state. In this case, it is desirable to output information for preventing forgotten items (hereinafter referred to as “information for preventing forgotten items”) as early as possible. However, it is not possible to adequately support forgotten object prevention simply by outputting forgotten object prevention information at a relatively early stage. If the forgotten item prevention information is output at a relatively early stage, the driver (or user) is left in the passenger compartment or the cargo compartment due to another subsequent work (for example, work related to payment). This is because there is a case where the user forgets to take out the existing object.

  Therefore, in one aspect, an object of the present invention is to appropriately support a user's leftover prevention in a vehicle related to a car sharing service and a vehicle related to a taxi service.

  Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

  [Embodiment 1] A forgotten object prevention support apparatus according to Embodiment 1 described below is applied to a vehicle related to a car sharing service. That is, the forgotten object prevention support apparatus is mounted on a vehicle related to the car sharing service. In the following description, a user refers to a user who can receive a car sharing service (here, a user who has registered as a member). The car sharing service refers to a service that allows a plurality of users registered as members to share and use a vehicle by paying a consideration. Further, the available user refers to a user who can use the vehicle 30 at that time.

  First, prior to the description of the lost article prevention support apparatus 1 according to the first embodiment, an outline of a car sharing service to which the lost article prevention support apparatus 1 according to the first embodiment is applied will be described.

  FIG. 1A is an explanatory diagram of an outline of a car sharing service. FIG. 1B is a schematic explanatory diagram of the fixing key box 32.

  FIG. 1A very schematically shows a vehicle 30 according to a car sharing service.

  The vehicle 30 may use only the engine as a power source, may use only an electric motor as a power source (that is, may be an electric vehicle), or may use both the engine and the electric motor as power sources. (That is, it may be a hybrid vehicle). When the vehicle 30 is a vehicle that uses only the engine as a power source, the engine is started / stopped by turning on / off the ignition switch. Moreover, when the vehicle 30 is an electric vehicle, the vehicle 30 is transitioned between a travelable state and a stopped state by turning on / off the power switch. Even if the ignition switch or the power switch is turned off, a predetermined electric load can operate based on a power source (so-called + B) from an in-vehicle battery (not shown).

  The vehicle 30 has a back door 30a. The back door may be in the form of a trunk or in the form of a hatchback door.

  The vehicle 30 includes a fixing key box 32 provided in the vehicle interior and a detection unit 8d provided outside the vehicle interior. The vehicle 30 may be the same as a normal vehicle except for the configuration related to the fixing key box 32 and the detection unit 8d.

  The fixing key box 32 is provided, for example, in a glove box. As shown in FIG. 1B, the fixing key box 32 includes a key hole 32a into which a fixing key (not shown) is inserted. The key inserted into the key hole 32a can be rotated and held between three positions by a user operation. The first position P1 represents a state in which the vehicle 30 can be used, the second position P2 represents a state in which the vehicle 30 can be returned, and the third position P3 leaves an object that can be left behind by the user in the vehicle. Corresponds to the confirmation position to be positioned when confirming whether there is any. The fixing key box 32 may be provided with characters representing the significance of the first position P1, the second position P2, and the third position P3. For example, the character “use” may be given to the first position P1, the character “return” may be given to the second position P2, and the character “confirmation” may be given to the third position P3. "May be given.

  The fixing key inserted into the fixing key box 32 may be the same as the vehicle key (key used for locking the door) or may be different. The fixing key box 32 may be configured such that the fixing key can be removed only at the first position P1. In this case, since the user cannot remove the fixing key at the second position P2 or the third position P3, the management of the fixing key is easy.

  In the following, as an example, it is assumed that the fixing key is common or integral with the vehicle key, and is configured so that the fixing key can be removed only at the first position P1. Therefore, when the fixing key is operated (the position is changed), the power switch or the ignition switch of the vehicle 30 is in the off state. In the configuration in which the fixing key is separate from the vehicle key, the fixing key box 32 can be operated only when the power switch or the ignition switch of the vehicle 30 is off. It may be.

  The detection unit 8d may be provided at any location outside the vehicle body. For example, in FIG. 1A, it is provided in the rear side (for example, C peeler) of the side part of a vehicle body.

  In the first embodiment, as an example, the detection unit 8d detects contact or proximity of a member card (an example of a predetermined object) possessed by the user. For example, the detection unit 8d has a communication function and can read the member identification information given to the member card. In this case, when the control device of the vehicle 30 (not shown, for example, a forgotten object prevention support device 1 described later) detects contact or proximity of the member card via the detection unit 8d, based on the member identification information of the member card, It may be determined whether or not the user who possesses the membership card is an available user (for example, a reserved user). Hereinafter, an event in which the control device of the vehicle 30 detects contact or proximity of an object (for example, a membership card) possessed by an available user via the detection unit 8d is referred to as a “touch event”. Note that a control device (not shown) of the vehicle 30 may lock / unlock the door by the door lock mechanism of the vehicle 30 based on the touch event.

  Instead of the membership card, a user's mobile terminal (another example of a predetermined object) may be used. In this case, for example, the user may cause the detection unit 8d to read the availability certificate downloaded to the mobile terminal (for example, a one-dimensional or two-dimensional barcode). When the control device (not shown) of the vehicle 30 detects the contact or proximity of the mobile terminal via the detection unit 8d, the user who owns the mobile terminal can use the user based on the presence / absence of the use certificate. It may be determined whether or not. And the control apparatus of the vehicle 30 may detect a touch event, when the user who possesses a portable terminal determines with being a user who can utilize.

  FIG. 1C is an explanatory diagram of state transition of the car sharing service. In the first embodiment, as an example, the state of the car sharing service is transitioned between four states, that is, the available state S1, the returnable state S2, the intermediate state S3, and the service end state S4. The available state S1 is formed when the fixing key is in the first position P1. The returnable state S2 is formed when the fixing key is at the second position P2. The intermediate state S3 is formed when the fixing key is at the third position P3.

  In the available state S <b> 1, an available user can change the vehicle 30 to a travelable state by turning on the power of the vehicle 30 or turning on the ignition switch.

  From the returnable state S2, a transition is made to the service end state S4 in response to the touch event. In addition, the service end state S4 transitions to the returnable state S2 in response to the touch event.

  The intermediate state S3 is a state between the available state S1 and the returnable state S2. The transition from the usable state S1 to the returnable state S2 and the transition from the returnable state S2 to the usable state S1 involve a transition to the intermediate state S3. For example, when the user performs a turning operation to turn the fixing key from the first position P1 to the second position P2, the fixing key turns to the second position P2 via the third position P3. Therefore, in this case, the transition from the available state S1 to the returnable state S2 is accompanied by the transition to the intermediate state S3.

  In the service end state S4, a user other than an available user (particularly a user who has finished using) cannot access the inside of the vehicle (including both the vehicle interior and the cargo compartment, the same applies below) without a penalty. The penalty is an economic penalty imposed on the user, such as payment of an additional fee or a new reservation. Accordingly, when the service end state S4 is reached, the consideration (use fee) for the current use is substantially determined.

  In the following, as shown in FIG. 1C, a state in which the state of the car sharing service is in any one of the available state S1, the returnable state S2, and the intermediate state S3 is referred to as “service in use”.

  Next, the forgotten object prevention support apparatus 1 according to the first embodiment mounted on the vehicle 30 will be described.

  FIG. 2 is a diagram illustrating a hardware configuration of the forgotten object prevention support apparatus 1. FIG. 2 schematically illustrates another in-vehicle electronic device 8 (an electronic device mounted on the vehicle 30) in association with the hardware configuration of the left-behind item prevention support device 1.

  The in-vehicle electronic device 8 includes a speaker 8a, a display 8b, a door switch 8c, and the like. The in-vehicle electronic device 8 includes means (not shown) for detecting the state of the fixing key of the fixing key box 32 described above, and a detection unit 8d.

  From the speaker 8a, second information to be described later is output under the control of the forgotten object prevention support apparatus 1.

  First information described later is output to the display 8b under the control of the forgotten object prevention support apparatus 1. For example, a navigation screen generated by a navigation device (one element of the in-vehicle electronic device 8, not shown), a screen generated by a multimedia system, or the like is displayed. In addition, the display 8b may be realized by a head-up display, a meter, or the like. Further, instead of or in addition to the display 8b, a display of a portable terminal that the user brings into the vehicle interior may be used.

  The door switch 8c is turned on / off according to the opening / closing of the back door 30a.

  The thing-left-behind prevention support apparatus 1 is in the form of a computer, and may be embodied as an ECU (Electronic Control Unit), for example. As shown in FIG. 2, the lost-item prevention support apparatus 1 includes a CPU (Central Processing Unit) 11, a RAM (Random Access Memory) 12, a ROM (Read Only Memory) 13, an auxiliary storage device 14, and a drive. The apparatus 15 includes a communication interface 17, and a wired transmission / reception unit 25 and a wireless transmission / reception unit 26 connected to the communication interface 17.

  The auxiliary storage device 14 is, for example, an HDD (Hard Disk Drive), an EEPROM (Electrically Erasable Programmable Read-Only Memory), an SSD (Solid State Drive), or the like, and stores data related to application software or the like. .

  The wired transmission / reception unit 25 includes a transmission / reception unit capable of communicating using a wired network. The in-vehicle electronic device 8 is connected to the wired transmission / reception unit 25. However, a part or all of the in-vehicle electronic device 8 may be connected to the bus 19 or may be connected to the wireless transmission / reception unit 26.

  The wireless transmission / reception unit 26 is a transmission / reception unit capable of communicating using a wireless network. The wireless network may include a mobile phone wireless communication network, the Internet, World Wide Web, VPN (Virtual Private Network), WAN (Wide Area Network), and the like. The wireless transmission / reception unit 26 may include a near field communication (NFC) unit, a Bluetooth (registered trademark) communication unit, a Wi-Fi (Wireless-Fidelity) transmission / reception unit, an infrared transmission / reception unit, and the like. .

  The forgotten object prevention support apparatus 1 may be connectable to the recording medium 16. The recording medium 16 stores a predetermined program. The program stored in the recording medium 16 is installed in the auxiliary storage device 14 or the like of the forgotten object prevention support device 1 via the drive device 15. The installed predetermined program can be executed by the CPU 11 of the forgotten object prevention support apparatus 1. For example, the recording medium 16 is a recording medium such as a CD (Compact Disc) -ROM, a flexible disk, a magneto-optical disk, etc., which records information optically, electrically or magnetically, such as a ROM, a flash memory, etc. It may be a semiconductor memory or the like for electrically recording.

  FIG. 3 is a functional block diagram of the forgotten object prevention support apparatus 1.

  The thing-left-behind prevention support apparatus 1 includes a determination unit 102, a first event detection unit 104, a second event detection unit 106, and an output unit 107. The determination unit 102, the first event detection unit 104, the second event detection unit 106, and the output unit 107 can be realized by the CPU 11 executing one or more programs in the storage device (for example, the ROM 13), respectively.

  The determination unit 102 determines the possibility that an object that can be left behind by the user is left in the passenger compartment or the cargo compartment of the vehicle 30 (hereinafter also referred to as “object remaining possibility”). For example, the determination unit 102 may determine the remaining possibility of an object by quantifying it in three or more stages, or may derive an estimated value (binary value) indicating the presence or absence of an object that can be left behind by the user. The determination unit 102 may determine the possibility of the object remaining by any method. For example, the possibility of an object remaining in the vehicle interior may be determined using a camera and / or a load sensor provided in the vehicle interior. Further, the possibility of remaining objects in the cargo compartment may be determined using a load sensor or the like provided in the cargo compartment, or a line sensor or the like provided between the cargo compartment and the passenger compartment (rear seat). It may be determined using. The line sensor optically detects whether or not an object has passed. In this case, the determination unit 102 can determine the remaining possibility of the object based on the detection result by the line sensor. For example, although the determination unit 102 detects the passage of an object based on the detection result of the line sensor in the available state S1, the line in the subsequent state other than the available state S1 (for example, the intermediate state S3) When the passage of the object is not detected based on the detection result by the sensor, it is determined that there is a possibility that the object remains in the cargo compartment (there is an object that can be left behind by the user in the cargo compartment).

  In the first embodiment, as an example, the determination unit 102 performs a determination process that determines, based on whether the back door 30a is opened or closed, using a binary value. Whether the back door 30a is opened or closed can be determined based on information from the door switch 8c. Therefore, in this case, the possibility of remaining objects can be determined with a simple configuration using the existing door switch 8c as compared with the case where a camera or the like is used.

  For example, the determination unit 102 detects opening / closing of the back door 30a in a state other than the available state S1 thereafter (for example, the intermediate state S3) even though the opening / closing of the back door 30a is detected in the available state S1. If not, it is determined that there is a possibility that an object remains in the cargo compartment. This is because it can be estimated that there is a high possibility that the baggage has not been taken out after the baggage has been placed in the luggage compartment in the available state S1. On the other hand, the determination unit 102 detects opening / closing of the back door 30a in the available state S1, but detects opening / closing of the back door 30a in a state other than the available state S1 thereafter (for example, the intermediate state S3). Then, it is determined that there is no possibility of the object remaining in the cargo compartment (there is no object that can be left behind by the user in the cargo compartment). This is because it can be estimated that the baggage has been put in the luggage compartment in the available state S1, but the baggage has been taken out after that.

  In addition, when the opening / closing of the back door 30a is not detected in the available state S1, the determination unit 102 determines whether to detect the opening / closing of the back door 30a in a state other than the available state S1 thereafter (for example, the intermediate state S3). Regardless of this, it is determined that there is no possibility of the object remaining in the cargo compartment (there is no object that can be left behind by the user in the cargo compartment).

  In this manner, since the user puts an object (typically, a luggage) into the cargo compartment or the user takes out the object from the cargo compartment involves opening and closing the back door 30a, this point is used. By doing so, it is possible to determine the possibility of the object remaining in the cargo compartment with relatively high accuracy.

  The determination unit 102 may perform a determination process every predetermined period, or may perform the determination process according to a predetermined rule. In the first embodiment, as an example, when the state of the car sharing service is the available state S1, the determination unit 102 performs a determination process every predetermined period, and the state of the car sharing service is the intermediate state S3 or the usage state. In the returnable state S2 after the possible state S1, the determination process is performed at a cycle according to the latest determination result. That is, when the latest determination result indicates “there is an object that can be forgotten by the user in the luggage compartment”, the determination unit 102 continues the determination process at predetermined intervals. On the other hand, when the most recent determination result indicates that “there is no object that can be left behind by the user in the luggage compartment”, the determination unit 102 stops the determination process. Note that the determination unit 102 does not perform the determination process when the state of the car sharing service is the service end state S4.

  The first event detection unit 104 detects the first event in a stage before the service end state S4 of the car sharing service (a stage before the service end). The first event is preferably different from a single event that is an off event of the power switch or the ignition switch of the vehicle 30. As a result, it is possible to prevent the output of forgotten-thing prevention information described later due to a power switch off event or the like when stopping at a stopover such as a service area. The off event of the power switch or ignition switch of the vehicle 30 is an event in which the power switch or ignition switch of the vehicle 30 transitions from the on state to the off state.

  The first event may be an event that occurs after an off event of the power switch or the ignition switch of the vehicle 30, or an event that occurs before an off event of the power switch or the ignition switch of the vehicle 30, It may be an event that occurs regardless of the off event of the power switch or the ignition switch of the vehicle 30.

  The first event is preferably detected based on an input (an example of the first input) performed by the user in the passenger compartment. As a result, the first event is detected relatively early with respect to the timing of a touch event that can occur thereafter (an input for changing the state of the car sharing service to the service end state S4 and input performed by the user outside the passenger compartment). it can. As a result, the second information (described later) in response to the detection of the first event can be output before the user goes out of the passenger compartment.

  In the first embodiment, as an example, the first event is an event that suggests a state immediately before the end of the service of the car sharing service (hereinafter referred to as “a state immediately before the end”). Specifically, the first event is a turning operation of the fixing key from the third position P3 to the second position P2 (that is, the transition from the intermediate state S3 of the car sharing service state to the returnable state S2). . The turning operation of the fixing key from the third position P3 to the second position P2 is realized as a series of turning operations of the fixing key from the first position P1 to the second position P2 via the third position P3. It may be possible. Note that the turning operation of the fixing key from the third position P3 to the second position P2 is an input that suggests the user's intention to return the vehicle and is performed in the passenger compartment by the user. This is because the fixing key box 32 is in the passenger compartment, and the transition from the intermediate state S3 to the returnable state S2 is highly likely to be performed at a stage before the service end state S4.

  In the modification, the first event detection unit 104 is an event that causes a transition from the intermediate state S3 of the car sharing service state to the returnable state S2, and a subsequent predetermined door (a door other than the back door). Typically, a combination with an opening / closing event of the driver's seat side door) may be detected as the first event. The predetermined door opening / closing event can be determined based on information from a door switch (not shown) that is turned on / off in response to the opening / closing of the predetermined door.

  In another modification, the first event detection unit 104 is an event in which a predetermined time ΔT2 elapses from the time when the state of the car sharing service transitions from the intermediate state S3 to the returnable state S2. The predetermined time ΔT2 is adapted to elapse until the state of the car sharing service transitions to the service end state S4.

  The second event detection unit 106 detects the second event before the first event occurs. The second event is set according to the content of the first event, and is optional. For example, the ignition switch or power switch off event at the destination being guided by the navigation device or the car sharing parking lot, or fixed It may be a turning operation of the key for the third position P3.

  The second event is preferably detected based on an input (an example of a second input) performed by the user in the passenger compartment. As a result, like the first event, the first information (described later) in response to the detection of the second event can be output before the user goes out of the passenger compartment.

  In the first embodiment, as an example, the second event detection unit 106 detects, as a second event, an event in which the state of the car sharing service lasts for a predetermined time ΔT3 in the intermediate state S3. The predetermined time ΔT3 is set to be significantly longer than the instantaneous duration of the intermediate state S3 associated with the turning operation of the fixing key from the first position P1 to the second position P2. That is, the second event detection unit 106 detects an event in which the fixing key is located at the third position P3 for a predetermined time ΔT3 as the second event. In the first embodiment, the operation of positioning the fixing key at the third position P3 for the predetermined time ΔT3 is an example of the second input performed by the user in the vehicle interior.

  The operation of turning the fixing key from the first position P1 to the third position P3 and positioning it for a predetermined time ΔT3 is an operation of changing the fixing key from the first position P1 (for example, the power switch of the vehicle 30 or the ignition switch). This is an operation with an off event), which suggests the occurrence of the first event thereafter. In addition, after the user has positioned the fixing key at the third position P3 for a predetermined time ΔT3, the user can turn the fixing key to the first position P1, and the user can turn to the second position P2. Is much lower than sex. The third position P3 is a position where the fixing key is positioned when the user checks whether or not an object that can be left behind remains in the vehicle. From this point, the second event suggests a transition (first event) from the intermediate state S3 to the returnable state S2 thereafter.

  The output unit 107 executes an output process for outputting forgotten thing prevention information (first information to be described later) for preventing the user from forgetting. The output unit 107 includes a first output unit 108 and a second output unit 110.

  When the second event detection unit 106 detects the second event, the first output unit 108 outputs first information for preventing the user from forgetting based on the determination result by the determination unit 102. Specifically, the first output unit 108 outputs the first information when the determination result by the determination unit 102 indicates that “an object may remain in the cargo compartment”. The determination result by the determination unit 102 used at this time may be the latest determination result after the second event detection unit 106 detects the second event, or the second event detection unit 106 The determination result at the time when the second event is detected may be the determination result immediately before the time when the second event detection unit 106 detects the second event.

  In addition, when the determination result by the determination unit 102 indicates “there is no possibility that an object will remain in the cargo compartment”, the first output unit 108 may output information indicating that. In this case, the user can confirm through the output of the information that it has been determined that there is no possibility of the object remaining in the cargo compartment.

  In the first embodiment, as an example, the first output unit 108 outputs the first information to the display 8b. The first information may be in the form of an alarm. For example, the first information may be in the form of a text message that tells the user that there is a possibility that an object will remain in the cargo compartment. In a modification, instead of or in addition to the output on the display 8b, the first information may be output by a sound (for example, in the form of an alarm sound or a voice message) via the speaker 8a.

  When the first event detection unit 104 detects the first event, the second output unit 110 outputs second information for preventing the user from forgetting based on the determination result by the determination unit 102. Specifically, the second output unit 110 outputs the second information when the determination result by the determination unit 102 indicates “there is a possibility that an object remains in the luggage compartment”. The determination result by the determination unit 102 used at this time may be the latest determination result after the time point when the first event detection unit 104 detects the first event, or the first event detection unit 104 may The determination result at the time when the first event is detected may be the determination result immediately before the time when the first event detection unit 104 detects the first event.

  In addition, when the determination result by the determination unit 102 indicates “there is no possibility that an object remains in the cargo compartment”, the second output unit 110 may output information indicating that. In this case, the user can confirm through the output of the information that it has been determined that there is no possibility of the object remaining in the cargo compartment.

  In the first embodiment, as an example, the second output unit 110 outputs the second information via the speaker 8a. The second information may be in the form of a warning sound or a voice message that tells the user that there is a possibility that an object will remain in the cargo compartment. In the modification, the second information may be output to the display 8b instead of or in addition to the output via the speaker 8a. The output of the second information may be realized by blinking a light or sounding a horn.

  When the first information and the second information are in the form of an alarm, the second information is preferably in a form with a higher alerting degree than the first information. This is because the timing at which the second information is output is later than the timing at which the first information is output and is close to the service end point. In the service end state S4, as described above, the user cannot access the inside of the vehicle without a penalty. Therefore, the output of the first information and the second information before the service end state S4 is formed prevents the left behind in the cargo room. Useful for support.

  Hereinafter, outputting the first information and the second information as described above is also referred to as “output of information for preventing left behind items”.

  FIG. 4 is an explanatory diagram of an operation example of the forgotten object prevention support apparatus 1 according to the first embodiment. The horizontal axis represents time, the occurrence of each event and the output timing of the first information and the second information are shown in time series. Indicates the occurrence of each event and the accompanying state transition of the car sharing service, the middle row indicates the output mode of the first information and the second information, and the lower row indicates the transition of the determination result by the determination unit 102. In the middle stage, periods T1 and T2 indicate the output state, and in the lower stage, “1” indicates a state in which the determination unit 102 determines that there is a possibility that an object remains in the cargo compartment. "Represents a state in which the determination unit 102 determines that there is no possibility of the object remaining in the cargo compartment.

  As shown in FIG. 4, in a situation where the state of the car sharing service is available, when the fixing key is turned to the third position P3 at time t0, the state of the car sharing service is , Transition to an intermediate state. When the second event is detected after the predetermined time ΔT3 has elapsed since that time, the first output unit 108 outputs the first information based on the determination result by the determination unit 102 being “1”. The first information may be output for a certain period of time, or may be output until the first predetermined stop condition is satisfied. The first predetermined stop condition is that the fixing key is subsequently changed to another position (typically, the second position P2), a certain period of time has elapsed thereafter, and the determination unit 102 thereafter This may be established when any of the determination results changing to “0” is satisfied.

  Thereafter, when the first event is detected, the state of the car sharing service transitions to a returnable state. At this time, the second output unit 110 outputs the second information based on the determination result by the determination unit 102 being “1”. The second information may be output for a certain period of time, or may be output until a second predetermined stop condition is satisfied. The second predetermined stop condition is that the state of the car sharing service subsequently transitions to the service end state S4, that a certain time has elapsed thereafter, and that the fixing key is subsequently changed to another position, and It may be established when any of the determination results by the determination unit 102 subsequently changed to “0” is satisfied. In the example illustrated in FIG. 4, the output of the second information is stopped in response to the determination result by the determination unit 102 changing to “0” at time t1.

  By the way, in the vehicle 30 related to the car sharing service, a state (service end state S4) in which access to the inside of the vehicle without a penalty is prohibited at the end of the service is formed. In this case, even if the user notices a forgotten item in the vicinity of the vehicle 30, the user falls into a state where the forgotten item cannot be collected without a penalty (for example, an additional fee).

  In this regard, according to the first embodiment, in a situation where the determination unit 102 determines that there is a possibility that an object remains in the cargo compartment, two states formed before the service end state S4, that is, an intermediate state In S3 and the returnable state S2, the first information and the second information are output, respectively. As a result, it is possible to appropriately support the user's forgetfulness prevention.

  For example, before returning, the user first performs an operation of turning the fixing key from the first position P1 to the third position P3, and an object that can be left behind remains in the cargo room based on whether or not the first information is output. You can judge the possibility of being. When the first information is output, the cargo room can be confirmed as necessary, and an object that can be left behind can be taken out in advance. Then, after that, an operation of turning the fixing key from the third position P3 to the second position P2 is performed, and based on the presence or absence of the output of the second information, there is a possibility that an object that can be left behind is still left in the cargo compartment. I can judge. For example, when the second information is not output, the user can form the service end state S4 by bringing the membership card close to or in contact with the detection unit 8d with peace of mind.

  Further, according to the first embodiment, by providing the intermediate state S3, it is possible to reduce the possibility that the forgotten object prevention information is output at an unnecessary timing as compared with the configuration in which the intermediate state S3 is not provided. For example, in the configuration in which the first information is output in response to all the ignition switch off events, there is a possibility that the information for preventing forgotten items may be output at the timing when the user stops at a stopover such as a service area. is there. According to the first embodiment, since the first information is output in response to the second event that can be detected in the intermediate state S3, such a possibility can be reduced.

  Next, with reference to FIG. 5 to FIG. 7, a process executed by the forgotten object prevention support apparatus 1 will be described.

  FIG. 5 to FIG. 7 are schematic flowcharts showing an example of processing executed by the forgotten object prevention support apparatus 1.

  FIG. 5 shows the overall processing executed by the forgotten object prevention support apparatus 1, FIG. 6 shows an example of the determination processing of FIG. 5, and FIG. 7 shows an example of the output processing of FIG. 6 is executed by the determination unit 102, and the output process of FIG. 7 is executed by the output unit 107 (the first output unit 108 and the second output unit 110). The process shown in FIG. 5 may be repeatedly executed at predetermined intervals.

  In step S500, the forgotten object prevention support apparatus 1 determines whether or not the service is being used. The use of the service is as described above. If the determination result is “YES”, the process proceeds to step S505, and otherwise, the process proceeds to step S502.

  In step S502, the forgotten object prevention support 1 determines whether or not a touch event has been detected in the service end state S4. If the determination result is “YES”, the process proceeds to step S504, and otherwise, the process of the current cycle is ended.

  In step S504, the thing-left-behind prevention support apparatus 1 starts the operation of the thing-left-behind prevention support function. When the operation of the lost article prevention support function is started, the lost article prevention support function by the lost article prevention support apparatus 1 is operated until the end state (see step S514).

  In step S505, the forgotten object prevention support apparatus 1 determines whether the state of the car sharing service has transitioned to the service end state S4. If the determination result is “YES”, the process proceeds to step S514, and otherwise, the process proceeds to step S506.

  In step S506, the forgotten object prevention support apparatus 1 records the state of the door switch 8c and the like. For example, the forgotten object prevention support apparatus 1 records the state of the door switch 8c or the like in the auxiliary storage device 14 or the like. Hereinafter, the data recorded in step S506 is referred to as “recording data”.

  In step S <b> 508, the forgotten object prevention support apparatus 1 performs a determination process by the determination unit 102. An example of the determination process will be described later with reference to FIG.

  In step S510, the forgotten object prevention support apparatus 1 determines whether the state of the car sharing service is the intermediate state S3 or the returnable state S2 after the useable state S1. If the determination result is “YES”, the process proceeds to step S 512, and otherwise, the process of the current cycle ends.

  In step S512, the forgotten object prevention support apparatus 1 determines whether or not the determination flag F is “0”. The determination flag F being “0” indicates that the determination result of the determination unit 102 is “there is no object that can be left behind by the user in the luggage compartment”. The initial value of the determination flag F (the value when the lost article prevention support function is activated) is “0”. The determination flag F being “1” indicates that the determination result of the determination unit 102 is “there is an object that can be left behind by the user in the luggage compartment”. If the determination result is “YES”, the process proceeds to step S514, and otherwise, the process proceeds to step S516.

  In step S514, the thing-left-behind prevention support apparatus 1 complete | finishes the operation | movement of a thing-left-hands prevention support function. At this time, the forgotten object prevention support apparatus 1 resets various flags (for example, a determination flag F, a first information output flag F1, etc.) described later as an initialization process. Moreover, when the first information or the second information is output, the forgotten object prevention support apparatus 1 stops the output of the first information or the second information.

  In step S <b> 516, the forgotten object prevention support apparatus 1 executes an output process using the output unit 107. An example of the output process will be described later with reference to FIG.

  According to the process shown in FIG. 5, when the operation of the lost-item prevention support function is started, the lost-item prevention support function by the lost-item prevention support device 1 operates thereafter until the end state (see step S514). When the lost-item prevention support function is activated, a determination process is executed, and an output process is executed according to the result of the determination process.

  Next, the determination process shown in FIG. 6 will be described.

  In step S600, the determination unit 102 determines whether the state of the car sharing service is the intermediate state S3 or the returnable state S2 after passing through the available state S1. If the determination result is “YES”, the process proceeds to step S602, and otherwise, the process proceeds to step S608.

  In step S602, the determination unit 102 determines whether or not the determination flag F is “1”. If the determination result is “YES”, the process proceeds to step S604, and otherwise, the process of the current cycle is ended.

  In step S604, the determination unit 102 determines whether the back door 30a has been opened / closed in the current state (the intermediate state S3 or the returnable state S2 after the use state S1) based on the recording data obtained in step S506. Determine whether. If the determination result is “YES”, the process proceeds to step S606, and otherwise, the process of the current cycle is terminated.

  In step S606, the determination unit 102 resets the determination flag F to “0”.

  In step S608, the determination unit 102 determines whether or not the determination flag F is “0”. If the determination result is “YES”, the process proceeds to step S610, and otherwise, the process of the current cycle is terminated.

  In step S610, the determination unit 102 opens and closes the back door 30a in the current state (the returnable state S2 before reaching the available state S1 or the available state S1) based on the recording data obtained in step S506. It is determined whether or not there was. If the determination result is “YES”, the process proceeds to step S612, and otherwise, the process of the current cycle is ended.

  In step S612, the determination unit 102 sets the determination flag F to “1”.

  According to the process shown in FIG. 6, the determination flag F is set to “1” in the available state S1, etc., and then the state of the car sharing service is the returnable state after passing through the intermediate state S3 or the available state S1. If the opening / closing of the back door 30a is detected under the condition of S2, the determination flag F is reset to “0” (step S606). This is because there is a high possibility that an object that can be forgotten is taken out of the luggage compartment by the user in a situation where the state of the car sharing service is the intermediate state S3 or the returnable state S2 after the useable state S1. It is. On the other hand, in a situation where the determination flag F is set to “1” in the available state S1 or the like, and then the state of the car sharing service is the intermediate state S3 or the returnable state S2 via the available state S1, If opening / closing of the back door 30a is not detected (“NO” in step S604), the determination flag F is maintained at “1”. In this case, the output process shown in FIG. 7 is executed.

  Next, the output process shown in FIG. 7 will be described.

  In step S700, the output unit 107 determines whether the state of the car sharing service is the intermediate state S3. If the determination result is “YES”, the process proceeds to step S702, and otherwise (that is, if the state of the car sharing service is the returnable state S2 after being available), the process proceeds to step S718.

  In step S702, the output unit 107 determines whether or not the first information output flag F1 is “0”. The first information output flag F1 being “0” indicates that the first information is not output. The first information output flag F1 being “1” indicates that the first information is output in response to the second event detection unit 106 detecting the second event. The initial value of the first information output flag F1 (the value when the lost article prevention support function is activated) is “0”. If the determination result is “YES”, the process proceeds to step S704, and otherwise, the process proceeds to step S712.

  In step S704, the output unit 107 determines whether the second event detection unit 106 has detected the second event. The method for detecting the second event is as described above. If the determination result is “YES”, the process proceeds to step S706, and otherwise, the process of the current cycle is terminated.

  In step S706, the output unit 107 sets the first information output flag F1 to “1”.

  In step S708, the output unit 107 starts a timer Tm1 corresponding to the upper limit value of the output period of the first information. The timer Tm1 times out when it reaches the upper limit of the output period of the first information after startup. The upper limit value of the output period of the first information is defined in advance.

  In step S <b> 710, the output unit 107 enters a state in which the first information is output by the first output unit 108. The output method of the first information is as described above.

  In step S712, the output unit 107 determines whether or not the timer Tm1 has timed out. If the determination result is “YES”, the process proceeds to step S714, and otherwise, the process proceeds to step S710.

  In step S714, the output unit 107 resets the first information output flag F1 to “0”.

  In step S718, the output unit 107 determines whether or not the second information output flag F2 is “0”. The second information output flag F2 being “0” indicates that the second information is not being output. The second information output flag F2 being “1” indicates that the second information is output in response to the detection of the first event by the first event detection unit 104. The initial value of the second information output flag F2 (the value when the lost article prevention support function is activated) is “0”. If the determination result is “YES”, the process proceeds to step S720, and otherwise, the process proceeds to step S730.

  In step S720, the output unit 107 initializes the first information output flag F1 and the output state of the first information. Specifically, when the first information output flag F1 is “1”, the first information output flag F1 is reset to “0”, and the first information is output by the first output unit 108. When there is, the output of the first information is stopped.

  In step S722, the output unit 107 sets the second information output flag F2 to “1”.

  In step S724, the output unit 107 starts a timer Tm2 corresponding to the upper limit value of the output period of the second information. The timer Tm2 times out when it reaches the upper limit of the output period of the second information after being activated. The upper limit value of the output period of the second information is defined in advance.

  In step S726, the output unit 107 is in a state in which the second output unit 110 outputs the second information. The method for outputting the second information is as described above.

  In step S730, the output unit 107 determines whether or not the timer Tm2 has timed out. If the determination result is “YES”, the process proceeds to step S732, and otherwise, the process proceeds to step S726.

  In step S732, the output unit 107 resets the second information output flag F2 to “0”.

  According to the process shown in FIG. 7, when an event in which the state of the car sharing service is maintained for the predetermined time ΔT3 in the intermediate state S3, that is, the second event is detected, the first information can be output. Further, when the turning operation of the fixing key from the third position P3 to the second position P2, that is, the first event is detected, the second information can be output. Therefore, according to the user's operation, the forgotten object prevention information (first information and second information) can be output in two states: an intermediate state S3 and a returnable state S2 after passing through the available state S1.

  [Embodiment 2] The forgotten object prevention support apparatus 1A according to the embodiment 2 sets the pre-end state without setting the intermediate state as the car sharing service state with respect to the forgotten object prevention support apparatus 1 according to the above-described embodiment 1. And the contents of the first event and the contents of the second event are different. In the following, the configuration unique to the second embodiment will be mainly described, and other similar configurations may be denoted by the same reference numerals, and description thereof may be omitted or simplified.

  FIG. 8A is a schematic explanatory diagram of a fixing key box 32A used in the car sharing service in the second embodiment.

  The fixing key box 32A is different from the fixing key box 32 used in the car sharing service in the first embodiment described above in that the third position P3 is not set. The fixing key box 32A may be configured such that the fixing key can be removed only at the first position P1. In the following, as an example, it is assumed that the fixing key is common or integral with the vehicle key, and is configured so that the fixing key can be removed only at the first position P1.

  FIG. 8B is an explanatory diagram of the state transition of the car sharing service in the second embodiment. In the second embodiment, as an example, the state of the car sharing service is transitioned between four states, that is, the available state S1, the returnable state S2, the pre-end state S31, and the service end state S4. .

  From the returnable state S2, a transition is made to the pre-end state S31 in response to the touch event. In addition, the service end state S4 transitions to the returnable state S2 in response to the touch event.

  The pre-end state S31 is a state between the returnable state S2 and the service end state S4. The transition from the returnable state S2 to the service end state S4 is accompanied by a transition to the pre-end state S31. The transition from the pre-end state S31 to the service end state S4 is realized when a predetermined transition condition is satisfied.

  Although the predetermined transition condition is arbitrary, in the second embodiment, as an example, the predetermined transition condition is satisfied when the duration of the pre-end state S31 reaches a predetermined time ΔT4. When there is a next reservation, the predetermined transition condition includes the time point when the duration of the pre-end state S31 reaches the predetermined time ΔT4 and the time point one hour before the use start time of the next reservation. It may be satisfied when the current point of time arrives at the earlier point of arrival.

  In the following, as shown in FIG. 8B, a state in which the state of the car sharing service is one of the available state S1, the returnable state S2, and the pre-termination state S31 is referred to as “service in use”. .

  The hardware configuration of the left-behind item prevention support device 1A may be as shown in FIG.

  FIG. 9 is a functional block diagram of the forgotten object prevention support apparatus 1A.

  The left-behind-item prevention support apparatus 1A includes a determination unit 102A, a first event detection unit 104A, a second event detection unit 106A, and an output unit 107. The determination unit 102A, the first event detection unit 104A, and the second event detection unit 106A can be realized by the CPU 11 executing one or more programs in the storage device (for example, the ROM 13), respectively.

  The determination unit 102 </ b> A determines the possibility that an object that can be forgotten by the user is left in the passenger compartment or the luggage compartment of the vehicle 30 (possibility of remaining object). The method for determining the possibility of remaining objects may be the same as in the first embodiment. That is, the determination processing algorithm itself may be the same.

  In the second embodiment, as an example, the determination unit 102A performs a determination process that determines, based on whether the back door 30a is opened or closed, using a binary value.

  For example, if the determination unit 102A does not detect the opening / closing of the back door 30a in the subsequent returnable state S2 or the pre-end state S31 even though the opening / closing of the back door 30a is detected in the available state S1, It is determined that there is a possibility that an object remains in the cargo compartment. On the other hand, the determination unit 102A detects the opening / closing of the back door 30a in the available state S1, but if the opening / closing of the back door 30a is detected in the subsequent returnable state S2 or the pre-end state S31, It is determined that there is no possibility of the object remaining (there is no object that can be left behind by the user in the luggage compartment).

  Further, when the determination unit 102A does not detect the opening / closing of the back door 30a in the available state S1, it does not matter whether the opening / closing of the back door 30a in the returnable state S2 or the pre-end state S31 is detected. Then, it is determined that there is no possibility of the object remaining in the cargo compartment (there is no object that can be left behind by the user in the cargo compartment).

  104A of 1st event detection parts detect a 1st event in the front stage (pre-stage of service end) of service end state S4 of a car sharing service.

  The first event is preferably detected based on an input (an example of a first input) performed by the user outside the vehicle compartment. Accordingly, it is possible to output the second information in response to the detection of the first event in a situation where the user is outside the vehicle compartment. As a result, the user can immediately open the back door 30a and access the luggage compartment.

  In the second embodiment, the first event is a touch event in the returnable state S2. The user's operation related to the touch event in the returnable state S2 is an input that suggests the user's intention to return the vehicle and is performed outside the vehicle compartment by the user.

  In the modification, the first event detection unit 104A detects, as a first event, an event for which the predetermined time ΔT5 has elapsed since the touch event in the returnable state S2 is detected. The predetermined time ΔT5 is adapted to elapse until the state of the car sharing service transitions to the service end state S4.

  The second event detection unit 106A detects the second event at a stage before the first event occurs. The second event is set according to the contents of the first event and is arbitrary. For example, the second event is a destination of the guidance being guided by the navigation device or an ignition switch or a power switch at a car sharing parking lot. It may be an off event.

  The second event is preferably detected based on an input (an example of a second input) performed by the user in the passenger compartment. Accordingly, it is possible to output the first information in response to the detection of the second event before the user goes out of the passenger compartment. Further, it is possible to detect the second event relatively early with respect to the first event that can occur thereafter and the transition timing to the service end state S4. As a result, it is possible to output the second information after an appropriate interval after the output of the first information.

  In the second embodiment, as an example, the second event is a rotation operation of the fixing key from the first position P1 to the second position P2 (that is, from the available state S1 of the car sharing service state to the returnable state S2). Event that causes a transition). In the second embodiment, the turning operation of the fixing key from the first position P1 to the second position P2 is an example of a second input performed by the user in the vehicle interior.

  Note that the turning operation of the fixing key from the first position P1 to the second position P2 is an operation for changing the state of the car sharing service to the returnable state S2, so that the subsequent first event (in the returnable state S2) This indicates the occurrence of a touch event. That is, the second event suggests the occurrence of the first event thereafter.

  According to the second embodiment, the same effects as those of the first embodiment described above can be obtained.

  That is, according to the second embodiment, in the situation where the determination unit 102A determines that there is a possibility that an object remains in the cargo compartment, two states formed before the service end state S4, that is, a returnable state In S2 and pre-end state S31, first information and second information are output, respectively. As a result, it is possible to appropriately support the user's forgetfulness prevention.

  Here, the returnable state S2 transits to the service end state S4 via the pre-end state S31. Therefore, before the service end state S4 is reached, the forgotten object prevention information can be output in two stages, and it is possible to appropriately assist the user in preventing forgotten object.

  According to the second embodiment, the first event is a touch event (operation outside the vehicle compartment) in the returnable state S2. Therefore, since there is a high possibility that the output of the second information is output when the user is outside the vehicle compartment, the second information is provided to the user outside the vehicle compartment who can access the cargo compartment more easily than the vehicle interior. Can be output. Thereby, the user can take out the object which can become a forgotten thing from a luggage compartment immediately with the output of 2nd information.

  Note that the process executed by the forgotten object prevention support apparatus 1A according to the second embodiment is substantially the same as the process shown in FIGS. 5 to 7, and the “returnable state S2 after useable state” is set to “end”. This corresponds to the replacement with the previous state S31 and the replacement of the intermediate state S3 with the returnable state S2 after the useable state. Also in this case, the first information can be output when the turning operation of the fixing key from the first position P1 to the second position P2, that is, the second event is detected. Further, when the touch event in the returnable state S2, that is, the first event is detected, the second information can be output. Accordingly, the forgotten object prevention information (first information and second information) can be output in the two states of the returnable state S2 after the useable state S1 and the pre-end state S31.

  [Embodiment 3] The forgotten object prevention support apparatus 1B according to Embodiment 3 does not set an intermediate state with respect to the forgotten object prevention support apparatus 1 according to Embodiment 1 described above, and does not include the second event detection unit 106. The difference is that the off-event detection unit 103B is added and the output unit 107 is replaced by the output unit 107B. In the following, a configuration unique to the third embodiment will be mainly described, and other similar configurations may be denoted by the same reference numerals, and description thereof may be omitted or simplified.

  In the third embodiment, the fixing key box 32A similar to the second embodiment described above is used (see FIG. 8A). That is, the fixing key box 32A is different from the fixing key box 32 used in the car sharing service in the first embodiment described above in that the third position P3 is not set.

  FIG. 10 is an explanatory diagram of the state transition of the car sharing service in the third embodiment. In the third embodiment, the state of the car sharing service is transitioned between three states, that is, the available state S1, the returnable state S2, and the service end state S4. The available state S1 is formed when the fixing key is in the first position P1. The returnable state S2 is formed when the fixing key is at the second position P2.

  From the returnable state S2, a transition is made to the service end state S4 in response to the touch event. In addition, the service end state S4 transitions to the returnable state S2 in response to the touch event.

  The hardware configuration of the thing-left-behind prevention support device 1B may be as shown in FIG.

  FIG. 11 is a functional block diagram of a left-behind item prevention support apparatus 1B according to the third embodiment.

  The forgotten object prevention support apparatus 1B includes a determination unit 102B, an off event detection unit 103B, a first event detection unit 104B, and an output unit 107B. The determination unit 102B, the off event detection unit 103B, the first event detection unit 104B, and the output unit 107B can be realized by the CPU 11 executing one or more programs in the storage device (for example, the ROM 13).

  The determination unit 102B determines the possibility that an object that can be forgotten by the user is left in the vehicle interior or the cargo compartment of the vehicle 30 (the possibility of the object remaining). The method for determining the possibility of remaining objects may be the same as in the first embodiment. That is, the determination processing algorithm itself may be the same.

  In the third embodiment, as an example, the determination unit 102B performs a determination process for determining the possibility of remaining of an object with a binary value based on whether the back door 30a is opened or closed.

  Specifically, the determination unit 102B detects the opening / closing of the back door 30a in the available state S1, but does not detect the opening / closing of the back door 30a in the subsequent returnable state S2, It is determined that there is a possibility that an object will remain. On the other hand, the determination unit 102B detects the opening / closing of the back door 30a in the available state S1, but when the opening / closing of the back door 30a is detected in the subsequent returnable state S2, the possibility of the object remaining in the luggage compartment (There is no object that can be left behind by the user in the luggage compartment).

  In addition, when the determination unit 102B does not detect the opening / closing of the back door 30a in the available state S1, the determination unit 102B does not detect whether the back door 30a is opened / closed in the returnable state S2 or not. (There is no object that can be left behind by the user in the luggage compartment).

  The off event detection unit 103B detects an off event of the power switch or the ignition switch of the vehicle 30 based on the state of the power switch or the ignition switch of the vehicle 30.

  The first event detection unit 104B detects the first event in a stage before the service end state S4 of the car sharing service (a stage before the service end). In the third embodiment, the first event is different from the off event of the power switch or the ignition switch of the vehicle 30.

  The first event is preferably detected based on an input (an example of the first input) performed by the user in the passenger compartment. As a result, the first event is detected relatively early with respect to the timing of a touch event that can occur thereafter (an input for changing the state of the car sharing service to the service end state S4 and input performed by the user outside the passenger compartment). it can. As a result, it is possible to output forgotten object prevention information (described later) in response to the detection of the first event before the user goes out of the passenger compartment.

  In the third embodiment, as an example, the first event is a turning operation of the fixing key from the first position P1 to the second position P2 (that is, from the available state S1 of the car sharing service state to the returnable state S2). Event that causes a transition). Note that the turning operation of the fixing key from the available state S1 to the second position P2 is an input that suggests the user's intention to return the vehicle and is performed by the user in the vehicle interior. This is because the fixing key box 32 is in the passenger compartment, and the transition from the available state S1 to the returnable state S2 is highly likely to be performed in the previous stage of the service end state S4.

  In the modification, the first event detection unit 104B includes an event that causes a transition from the available state S1 to the returnable state S2 in the state of the car sharing service, and a predetermined door (a door other than the back door). Yes, typically, a combination with the opening / closing event of the driver's seat side door) may be detected as the first event.

  In another modification, the first event detection unit 104B determines that an event for which the predetermined time ΔT2 has elapsed from the time when the state of the car sharing service transitions from the available state S1 to the returnable state S2 is the first event. You may detect as. The predetermined time ΔT2 is adapted to elapse until the state of the car sharing service transitions to the service end state S4.

  In another modification, the first event detection unit 104B may detect a destination being guided by the navigation device or an arrival event at a car sharing parking lot as the first event.

  When the off event of the power switch or the ignition switch of the vehicle 30 and the first event are detected, the output unit 107B executes an output process for outputting forgetting prevention information based on the determination result by the determination unit 102B. . As a result, compared with the case where the forgotten object prevention information is output based on the determination result by the determination unit only by detecting the off event of the power switch or the ignition switch of the vehicle 30, the forgotten object prevention information is output at a timing that is unnecessary. It is possible to reduce the possibility of being done. That is, it is possible to reduce the possibility that the forgotten object prevention information is output due to an off event of the power switch when the user stops at the service area.

  In the third embodiment, as described above, since the first event is a turning operation of the fixing key from the first position P1 to the second position P2, it occurs after the off event of the power switch or the ignition switch. Therefore, the detection of the first event means that the off event of the power switch or the ignition switch is also detected by the off event detection unit 103B. However, in a modified example, the first event may be an event that occurs before an off event of the power switch or the ignition switch. In this case, when the first event and a subsequent power switch or ignition switch off event are detected, the output unit 107B executes output processing based on the determination result by the determination unit.

  Specifically, when the first event detection unit 104B detects the first event, the output unit 107B outputs forgotten object prevention information based on the determination result by the determination unit 102B. For example, the output unit 107B outputs forgotten object prevention information when the determination result by the determination unit 102B indicates that there is a possibility that an object may remain in the cargo compartment. The determination result by the determination unit 102B used at this time may be a determination result immediately after the time point when the first event detection unit 104B detects the first event, or the first event detection unit 104B may The determination result at the time when the first event is detected may be a determination result immediately before the time when the first event detection unit 104B detects the first event.

  The forgotten object prevention information may be the same as either the first information or the second information according to the first embodiment described above, or is realized by a combination of the first information and the second information according to the first embodiment described above. May be.

  According to the third embodiment, under the situation where the determination unit 102B determines that there is a possibility that an object remains in the cargo compartment, the information for preventing forgotten items in the state before the service end state S4, that is, in the returnable state S2. Is output. As a result, it is possible to appropriately support the user's forgetfulness prevention.

  Next, with reference to FIG. 12, the process performed by the thing-left-behind prevention support apparatus 1B is demonstrated.

  FIG. 12 is a schematic flowchart illustrating an example of output processing according to the third embodiment. The output process shown in FIG. 12 may be executed as step S516 in the schematic flowchart shown in FIG. 5 according to the first embodiment. The schematic flowchart shown in FIG. 5 can also be applied to the third embodiment. At that time, the determination process of FIG. 6 may be executed as step S508 in the schematic flowchart shown in FIG. In this case, since the “intermediate state” is not set in the third embodiment, it is determined in step S510 or step S600 whether the state of the car sharing service is the returnable state S2 after the useable state S1. Will be. Accordingly, the output process shown in FIG. 12 is executed when the state of the car sharing service is the returnable state S2 after the availability state.

  In step S1202, the output unit 107B determines whether or not the information output flag F0 is “0”. The information output flag F0 being “0” indicates that the forgotten object prevention information is not output. The information output flag F0 being “1” indicates that the forgotten object prevention information is output in response to the detection of the first event by the first event detection unit 104B. If the determination result is “YES”, the process proceeds to step S1204, and otherwise, the process proceeds to step S1210.

  In step S1204, the output unit 107B sets the information output flag F0 to “1”.

  In step S1206, the output unit 107B activates a timer Tm0 corresponding to the upper limit value of the output period of the forgotten object prevention information. The timer Tm0 times out when the timer Tm0 reaches the upper limit of the output period of the forgotten object prevention information after being started. The upper limit value of the output period of the information for preventing lost items is defined in advance.

  In step S1208, the output unit 107B outputs forgotten object prevention information. The method for outputting the forgotten object prevention information is as described above.

  In step S1210, the output unit 107B determines whether or not the timer Tm0 has timed out. If the determination result is “YES”, the process proceeds to step S1212, and otherwise, the process proceeds to step S1208.

  In step S1212, the output unit 107B resets the information output flag F0 to “0”.

  According to the process shown in FIG. 12, when an event in which the state of the car sharing service transitions from the available state S1 to the returnable state S2, that is, the first event is detected, the forgotten object prevention information can be output. Thereby, it is possible to output the information for preventing forgotten things before reaching the service end state S4, and it is possible to appropriately support the user for preventing forgotten things.

  [Embodiment 4] The forgotten object prevention support apparatus 1C according to Embodiment 4 is applied to a vehicle related to a taxi service. Hereinafter, the vehicle refers to a taxi vehicle.

  The state of the taxi service is transitioned between a rental state, a payment state, and an idle state, although not shown. Hereinafter, the idle running state and the running state (that is, a state in which a significant vehicle speed is generated) are referred to as “service end state” relating to the taxi service.

  The hardware configuration of the forgotten object prevention support apparatus 1C may be as shown in FIG.

  FIG. 13 is a functional block diagram of the lost-item prevention support apparatus 1C.

  The left-behind-item prevention support device 1C includes a determination unit 102C, a third event detection unit 104C, a fourth event detection unit 106C, and an output unit 107C. The determination unit 102C, the third event detection unit 104C, the fourth event detection unit 106C, and the output unit 107C can be realized by the CPU 11 executing one or more programs in the storage device (for example, the ROM 13).

  The determination unit 102C is the same as the determination unit 102 according to the first embodiment described above except that the timing of the determination process is different. That is, the determination processing algorithm itself may be the same. In the fourth embodiment, as an example, the determination unit 102C performs a pre-determination process while the forgotten object prevention support function is not operating. A passenger (a user related to a taxi service, hereinafter simply referred to as a “user”) may put an object (such as a luggage) into a luggage compartment before boarding. The prior determination process is a process for detecting such an event. In the fourth embodiment, as an example, the determination unit 102C performs the determination process at predetermined intervals while the forgotten object prevention support function is operating.

  The third event detection unit 104C detects the third event before the end of the taxi service. The third event is preferably an event representing a service end intention related to the taxi service of the user. As an example, the third event is an event in which the state of the taxi service transitions from the rental state to the payment state. This is because the transition to the payment state accurately represents the user's intention to end the service. The state of the taxi service can be determined based on information from a taxi meter (not shown).

  In the modified example, the third event detection unit 104C includes an event that causes a transition from the rented state to the payment state in the taxi service state, and a subsequent opening / closing event of a predetermined door (rear seat door). May be detected as the third event. The opening / closing event of the rear seat door can be determined based on information from a door switch (not shown) that is turned on / off in response to the opening / closing of the predetermined door.

  In another modification, the third event detection unit 104C detects, as a third event, an event for which the predetermined time ΔTt has elapsed from the time when the taxi service state transitions from the rental state to the payment state. The predetermined time ΔTt is adapted to elapse until a fourth event described later occurs.

  In another modification, the third event detection unit 104C may detect an arrival event at the destination being guided by the navigation device as the third event. Alternatively, the third event detection unit 104C determines a combination of an arrival event at the destination being guided by the navigation device and an event that causes a transition from the rental state to the payment state in the taxi service state as the third event. You may detect as.

  The fourth event detection unit 106C detects the fourth event after the third event. The fourth event is preferably an event that occurs before the end of service. The service end point is a point at which access to the vehicle driver (taxi driver) becomes substantially impossible due to the vehicle leaving the user. For example, the fourth event detection unit 106C detects the fourth event based on whether or not a predetermined condition is satisfied after the third event. Although the predetermined condition is arbitrary, in the fourth embodiment, as an example, the predetermined condition is satisfied when a predetermined time ΔT6 has elapsed after the third event. The predetermined time ΔT6 is adapted to elapse until the taxi service state transitions to the service end state.

  The output unit 107 </ b> C executes output processing for outputting various types of information for preventing a user from forgetting things. The output unit 107C includes a first output unit 108C and a second output unit 110C.

  When the third event detection unit 104C detects the third event, the first output unit 108C outputs third information for preventing the user from forgetting based on the determination result by the determination unit 102C. For example, the first output unit 108 </ b> C outputs the third information when the determination result by the determination unit 102 </ b> C indicates that “an object may remain in the cargo compartment”. The determination result by the determination unit 102C used at this time may be the latest determination result after the time point when the third event detection unit 104C detects the third event, or the third event detection unit 104C The determination result at the time when the third event is detected may be a determination result immediately before the time when the third event detection unit 104C detects the third event.

  In addition, when the determination result by the determination unit 102C indicates “there is no possibility that an object remains in the cargo compartment”, the first output unit 108C may output information indicating that. In this case, the driver or the user can confirm through the output of the information that it has been determined that there is no possibility of the object remaining in the cargo compartment.

  The third information may be the same as the first information according to the first embodiment described above.

  When the fourth event detection unit 106C detects the fourth event, the second output unit 110C outputs fourth information for preventing the user from forgetting based on the determination result by the determination unit 102C. For example, the second output unit 110 </ b> C outputs the fourth information when the determination result by the determination unit 102 </ b> C indicates “there is a possibility that an object remains in the luggage compartment”. The determination result by the determination unit 102C used at this time may be the latest determination result after the time point when the fourth event detection unit 106C detects the fourth event, or the fourth event detection unit 106C The determination result at the time when the fourth event is detected may be the determination result immediately before the time at which the fourth event detection unit 106C detects the fourth event.

  In addition, when the determination result by the determination unit 102C indicates “there is no possibility that an object remains in the cargo compartment”, the second output unit 110C may output information indicating that. In this case, the driver or the user can confirm through the output of the information that it has been determined that there is no possibility of the object remaining in the cargo compartment.

  The fourth information may be the same as the second information according to the first embodiment described above.

  When the third information and the fourth information are in the form of an alarm, the fourth information is preferably in a form having a higher alerting degree than the third information. This is because the timing for outputting the fourth information is later than the timing for outputting the third information and is close to the timing for reaching the service end state. In the service end state, as described above, it becomes difficult for the user to collect forgotten things. Therefore, the output of the third information and the fourth information before the service end state is formed can prevent the forgotten things in the luggage compartment. Useful for support.

  Hereinafter, outputting the third information and the fourth information as described above is also referred to as “output of forgotten object prevention information”.

  By the way, in the vehicle which concerns on a taxi service, the period until the transition from a payment state to an idling state is indefinite. For example, the payment work may be long or short. Therefore, in the payment state, when there is a possibility that an object that can be left behind is left in the passenger compartment or the cargo compartment, it is desirable to output the information for preventing left behind as early as possible. However, it is not possible to adequately support forgotten object prevention simply by outputting forgotten object prevention information at a relatively early stage. If the forgotten item prevention information is output at a relatively early stage, the driver (or user) is left in the passenger compartment or the cargo compartment due to another subsequent work (for example, work related to payment). This is because there is a case where the user forgets to take out the existing object.

  In this regard, according to the fourth embodiment, when the determination unit 102C determines that there is a possibility that an object remains in the cargo compartment, the time when the third event before the service end state is detected and the service end state The third information and the fourth information are output at the time of detecting the fourth event that is likely to occur before. The third event is detected at a relatively early stage. The fourth event is likely to be detected after the third event and before the service termination state. As a result, it is possible to output the information for preventing forgotten things at two different timings, so that it is possible to appropriately support for the user to prevent forgetting things.

  Next, with reference to FIG.14 and FIG.15, the process performed by the thing-left-behind prevention support apparatus 1C is demonstrated.

  FIG. 14 and FIG. 15 are schematic flowcharts showing an example of processing executed by the forgotten object prevention support apparatus 1C. FIG. 14 shows the overall processing executed by the forgotten object prevention support apparatus 1C, and FIG. 15 shows an example of the output processing of FIG. The output process of FIG. 15 is executed by the output unit 107C (the first output unit 108C and the second output unit 110C). The process illustrated in FIG. 14 may be repeatedly executed at predetermined intervals.

  In step S1400, the thing-left-behind prevention support device 1C determines whether or not the item left behind prevention support function is operating. If the determination result is “YES”, the process proceeds to step S1408; otherwise, the process proceeds to step S1402.

  In step S1402, the forgotten object prevention support device 1C performs a pre-determination process by the determination unit 102C. If the determination unit 102C determines that there is an object that can be left behind by the user as a result of the determination process in advance, the determination unit 102C sets the determination flag F to “1”. On the other hand, the determination unit 102C maintains the determination flag F at “0” when it is determined that there is no object that can be left behind by the user as a result of the previous determination process. The determination flag F is as described in the first embodiment. Note that the prior determination process in step S1402 is less likely to be performed in a short cycle, and thus may be executed every predetermined number of predetermined cycles.

  In step S1404, the forgotten object prevention support apparatus 1C determines whether or not the determination flag F has changed from “0” to “1”. If the determination result is “YES”, the process proceeds to step S 1406, and otherwise, the process of the current cycle is terminated.

  In step S1406, the lost article prevention support device 1C starts the operation of the lost article prevention support function. When the lost article prevention support function is started, the lost article prevention support function by the lost article prevention support apparatus 1C operates until the end state (see step S1422).

  In step S1408, the forgotten object prevention support apparatus 1C determines whether or not the service is in an end state (idle driving state and driving state). If the determination result is “YES”, the process proceeds to step S 1424; otherwise, the process proceeds to step S 1410.

  In step S1410, the forgotten object prevention support apparatus 1C records the state of a vehicle door switch (not shown) or the like. For example, the forgotten object prevention support apparatus 1 generates the record data by recording the state of the door switch or the like in the auxiliary storage device 14 or the like.

  In step S1412, the left-behind-object prevention support device 1C executes a determination process by the determination unit 102C. An example of the determination process may be the same as the determination process performed by the determination unit 102 described above with reference to FIG. In this case, in step S600 of FIG. 6, the determination unit 102C determines whether or not the state of the taxi service is a payment state.

  In step S1414, the forgotten object prevention support apparatus 1C determines whether or not the state of the taxi service is a payment state. If the determination result is “YES”, the process proceeds to step S1416, and otherwise, the process of the current cycle ends.

  In step S1416, the forgotten object prevention support apparatus 1C determines whether or not the determination flag F is “1”. If the determination result is “YES”, the process proceeds to step S 1418; otherwise, the process proceeds to step S 1420.

  In step S1418, the forgotten object prevention support apparatus 1C performs output processing using the output unit 107C. An example of the output process will be described later with reference to FIG.

  In step S1420, the forgotten object prevention support apparatus 1C resets various flags described later (a third information output flag F3, a fourth information output flag F4, and a third information output end flag F5 described later) or “ Maintain 0 ". In addition, when the third information or the fourth information is output, the forgotten object prevention support apparatus 1C stops the output.

  In step S <b> 1422, the lost-item prevention support device 1 </ b> C ends the operation of the lost-item prevention support function.

  In step S1424, the left-behind-item prevention support device 1C resets the determination flag F and various flags described later (a third information output flag F3, a fourth information output flag F4, and a third information output end flag F5) as an initialization process. Alternatively, it is maintained at “0”.

  According to the process shown in FIG. 14, by performing the pre-determination process, the operation of the forgotten object prevention support function can be started when the user puts the luggage into the luggage room even before the user gets into the vehicle. When the lost-item prevention support function is activated, a determination process is executed, and an output process is executed according to the result of the determination process.

  Next, the output process shown in FIG. 15 will be described.

  In step S1500, the output unit 107C determines whether or not the third information output end flag F5 is “0”. The fact that the third information output end flag F5 is “1” indicates that the third information was output during the operation of the present lost article prevention support function, and the third information output end flag F5 is “0”. This means that the third information is not output during the operation of the lost-item prevention support function this time. The initial value of the third information output end flag F5 (the value when the lost article prevention support function is activated) is “0”. If the determination result is “YES”, the process proceeds to step S1502, and otherwise, the process proceeds to step S1517.

  In step S1502, the output unit 107C determines whether or not the third information output flag F3 is “0”. The third information output flag F3 being “0” indicates that the third information is not output. The third information output flag F3 being “1” indicates that the third information is output in response to the detection of the third event by the third event detection unit 104C. The initial value of the third information output flag F3 (the value when the lost article prevention support function is activated) is “0”.

  In step S1504, the output unit 107C sets the third information output flag F3 to “1”.

  In step S1506, the output unit 107C starts the timer Tm3 corresponding to the upper limit value of the output period of the third information. The timer Tm3 times out when it reaches the upper limit of the output period of the third information after activation. The upper limit value of the output period of the third information is defined in advance so as to be significantly shorter than the predetermined time ΔT6.

  In step S1508, the output unit 107C starts the timer Tm6. The timer Tm6 times out when a predetermined time ΔT6 elapses after activation. The predetermined time ΔT6 is as described above.

  In step S1510, output unit 107C outputs the third information.

  In step S1512, the output unit 107C determines whether or not the timer Tm3 has timed out. If the determination result is “YES”, the process proceeds to step S1514, and otherwise, the process proceeds to step S1510.

  In step S1514, the output unit 107C resets the third information output flag F3 to “0”.

  In step S1516, the output unit 107C sets the third information output end flag F5 to “1”.

  In step S1517, the output unit 107C determines whether or not the fourth information output flag F4 is “0”. The fourth information output flag F4 being “0” indicates that the fourth information is not output. The fourth information output flag F4 being “1” indicates that the fourth information is output in response to the detection of the fourth event by the fourth event detection unit 106C. The initial value of the fourth information output flag F4 (the value when the lost article prevention support function is activated) is “0”. If the determination result is “YES”, the process proceeds to step S1518, and otherwise, the process proceeds to step S1526.

  In step S1518, the output unit 107C determines whether or not the timer Tm6 has timed out. If the determination result is “YES”, the process proceeds to step S1520, and otherwise, the process proceeds to step S1526.

  In step S1520, the output unit 107C sets the fourth information output flag F4 to “1”.

  In step S1522, the output unit 107C starts the timer Tm4 corresponding to the upper limit value of the output period of the fourth information. The timer Tm4 times out when it reaches the upper limit of the output period of the fourth information after activation. The upper limit value of the output period of the fourth information is defined in advance.

  In step S1524, the output unit 107C outputs the fourth information.

  In step S1526, the output unit 107C determines whether or not the timer Tm4 has timed out. If the determination result is “YES”, the process proceeds to step S1528; otherwise, the process proceeds to step S1524.

  In step S1528, the output unit 107C resets the fourth information output flag F4 and the third information output end flag F5 to “0”, respectively.

  According to the processing shown in FIG. 15, in a situation where the determination unit 102 </ b> C determines that there is a possibility that an object remains in the cargo compartment, the third event that occurs before the service end state and the service end state occur. The third information and the fourth information are output in response to the fourth event having a high possibility. As a result, it is possible to appropriately support the user's forgetfulness prevention. Therefore, there is a high possibility that the forgotten object prevention information (third information and fourth information) can be output in two stages before reaching the service end state, and it is possible to appropriately support the user forgetting object prevention.

  Although each embodiment has been described in detail above, it is not limited to a specific embodiment, and various modifications and changes can be made within the scope described in the claims. It is also possible to combine all or a plurality of the components of the above-described embodiments.

  For example, in the first embodiment and the second embodiment described above, both the first output unit 108 and the second output unit 110 are provided, but either one may be omitted. In this case, a configuration similar to that of the third embodiment described above is realized.

  Further, in the first and second embodiments described above, when another event before reaching the service end state is detected, further information for preventing forgotten items is obtained based on the determination results by the determination units 102 and 102A. It may be output.

  Further, in the first embodiment described above (the same applies to the second embodiment and the like), the opening / closing of the back door 30a is detected based on the state of the door switch 8c of the back door 30a, but the present invention is not limited to this. For example, when the back door 30a is electrically operated, the opening / closing of the back door 30a may be detected based on operation information of a motor that drives the back door 30a.
