[Embodiment]
The on-vehicle monitoring device 1 according to the present embodiment is mounted on a vehicle 2 such as a car. The vehicle 2 is, for example, a passenger car having a wide compartment 201 such as a one-box car. In the passenger compartment 201, a plurality of seats 3 are arranged. The on-vehicle monitoring device 1 monitors an object (the monitoring target object 50) brought into the compartment 201, and notifies an occupant of the vehicle 2 when there is a change in the state of the object. The on-vehicle monitoring device 1 detects, for example, the RF tag 51 held by the monitored object 50 in the passenger compartment 201. The on-vehicle monitoring device 1 detects the RF tag 51 and, when the passenger gets off, notifies the portable terminal 5 registered in advance. The monitoring target object 50 is various articles which can be brought into the compartment 201, and examples thereof include a wallet, a bag, an umbrella, a game device, a leisure item, and the like. The passengers of the vehicle 2 include the driver of the vehicle 2 and a passenger other than the driver.

  In the following description, in the vehicle 2, the vehicle longitudinal direction corresponds to the full length direction of the vehicle 2. In the longitudinal direction of the vehicle, the side where the vehicle 2 moves forward may be referred to as the front, and the side where the vehicle 2 moves backward may be referred to as the rear. The lateral direction of the vehicle corresponds to the full width direction of the vehicle 2. In the vehicle left-right direction, the left side may be referred to as the left side toward the front in the vehicle longitudinal direction, and the right side may be referred to as the right side toward the front in the vehicle longitudinal direction. The longitudinal direction of the vehicle and the lateral direction of the vehicle are orthogonal to each other, and the longitudinal direction of the vehicle and the lateral direction of the vehicle are along the horizontal direction in a state where the vehicle 2 is positioned on the horizontal surface.

  The in-vehicle monitoring device 1 includes a reader unit 10, an electronic control unit (ECU) 20, a detection unit 30, a notification unit 40, and a wireless communication unit 60, as shown in FIG.

  The reader unit 10 is a so-called RF tag reader / writer, or simply referred to as a reader / writer, and periodically radiates radio waves into the compartment 201 and is an RF tag held by the monitored object 50 in the compartment 201. The identification information of the RF tag 51 is received from 51. The reader unit 10 is, for example, a communication device that performs wireless communication with the RF tag 51 using a radio frequency identifier (RFID). The reader unit 10 performs wireless communication with at least one RF tag 51. The reader unit 10 is disposed in the compartment 201. For example, as shown in FIG. 2 and FIG. 3, the leader portion 10 is disposed at an end portion on the vehicle front side of the inner roof 202 in the passenger compartment 201. The reader unit 10 corresponds to, for example, a passive RFID, transmits a radio wave (carrier wave) to supply power to the RF tag 51, and receives a reflected wave (subcarrier wave) to the radio wave from the RF tag 51. . Radio waves (reflected waves) from the RF tag 51 include identification information of the RF tag 51. Identification information of the RF tag 51 is a so-called tag ID, and is an identifier (unique ID) assigned to each RF tag 51. The reader unit 10 is connected to the ECU 20, emits a radio wave according to a control signal from the ECU 20, and outputs the received identification information and the like of the RF tag 51 to the ECU 20. The reader unit 10 has an antenna unit 11 as shown in FIG. The reader unit 10 radiates (transmits) radio waves to the radio wave radiation range 12 in the passenger compartment 201 via the antenna unit 11, and receives radio waves from the RF tag 51. The radio wave radiation range 12 is a range within which the radio wave emitted by the reader unit 10 can reach, and extends at least in the vehicle front-rear direction and the vehicle left-right direction in the passenger compartment 201. It is preferable that the radio wave radiation range 12 be set so as to include the entire area in the passenger compartment 201.

  The RF tag 51 is a microminiature communication device called an RFID tag, an IC tag, an electronic tag, or a contactless tag. The RF tag 51 is held by a monitored object 50 brought into the vehicle 2. The RF tag 51 is a so-called passive tag that is not equipped with a power source such as a battery and is activated by using a radio wave transmitted from the reader unit 10 as power. The RF tag 51 transmits the reflected wave (radio wave) to the radio wave received from the reader unit 10 to the reader unit 10. The radio wave transmitted (reply) to the reader unit 10 includes the identification information of the RF tag 51 described above. As illustrated in FIG. 1, the RF tag 51 includes an antenna unit 52, a memory 53, and a sensor 54. The reader unit 10 receives the radio wave from the reader unit 10 via the antenna unit 52 and transmits the radio wave to the reader unit 10. The memory 53 stores identification information of the RF tag 51 and the like. The sensor 54 detects the state of the monitored object 50, and stores the detection result in the memory 53 as sensor information. The sensor 54 is, for example, a temperature sensor or the like. When the sensor 54 is a temperature sensor, temperature data is stored in the memory 53 as sensor information. In this case, the RF tag 51 stores temperature data in the memory 53 each time a radio wave is received from the reader unit 10. The RF tag 51 may transmit temperature data to the reader unit 10 each time it receives a radio wave from the reader unit 10. The reader unit 10 receives sensor information from the RF tag 51. The ECU 20 controls the wireless communication unit 60 to transmit sensor information to the portable terminal 5 together with a notification signal described later.

  The ECU 20 is a control unit that is mounted on the vehicle 2 and controls the reader unit 10, the detection unit 30, the notification unit 40, and the wireless communication unit 60. The ECU 20 is configured to include an electronic circuit based on a known microcomputer including a CPU, a ROM, a RAM, and an interface. When the notification condition is satisfied, the ECU 20 of the present embodiment performs notification processing for controlling the wireless communication unit 60 so as to transmit a notification signal for notifying the notification means of the portable terminal 5. That is, the ECU 20 determines whether the notification condition is satisfied, and performs the notification process if the condition is satisfied. On the other hand, when the notification condition is not satisfied, the notification process is not performed. The notification condition is, for example, the case where the reader unit 10 receives the identification information of the RF tag 51 registered in advance, and the detection unit 30 detects the getting off of the passenger. The portable terminal 5 is a small, lightweight communication device that can be carried. The mobile terminal 5 is, for example, a mobile phone such as a smartphone, a PDA (Personal Digital Assistant), a tablet PC (Personal Computer), a notebook PC, a wearable terminal, or the like. The portable terminal 5 is carried by, for example, a passenger of the vehicle 2. The notification means of the portable terminal 5 displays a warning image on the display 41, sounds a warning sound from a speaker (not shown), or vibrates with a vibration function, for example, of the monitoring object 50 in the vehicle room 201. Informing the passenger that he or she has misplaced it. In addition, as notification means for the portable terminal 5, the passenger may be notified by receiving an e-mail from the wireless communication unit 60 on the vehicle 2 side, or an application installed on the portable terminal 5 may be used to It may be something to inform.

  As shown in FIG. 4, the ECU 20 has a notification target list 101 in which identification information of the RF tag 51 is registered. In the notification target list 101, identification information of the RF tag 51 and information of the portable terminal 5 are registered in association with each other. The notification target list 101 includes, for example, a tag ID 102, a telephone number 103, a MAC address 104, and a BD address 105. The information of the portable terminal 5 is, for example, the telephone number 103 of the portable terminal 5, the MAC address 104, the BD (Bluetooth (registered trademark) Device) address 105, and the like. The notification target list 101 is stored in advance in a memory (not shown) in the ECU 20 by a method described later. The ECU 20 determines whether the identification information of the RF tag 51 received by the reader unit 10 is registered in the notification target list 101 while satisfying the above-described notification condition. When the identification information of the RF tag 51 is registered in the notification target list 101, the ECU 20 performs notification processing. On the other hand, when the identification information of the RF tag 51 is not registered in the notification target list 101, the notification process is not performed.

  Further, the ECU 20 performs a notification process on the portable terminal 5 based on the information on the portable terminal 5 corresponding to the identification information of the RF tag 51 registered in the notification target list 101. Therefore, the ECU 20 can perform notification processing on different portable terminals 5 based on the information on different portable terminals 5 registered in the notification target list 101. The ECU 20 performs notification processing using the telephone number 103, the MAC address 104, and the BD address 105 of the portable terminal 5 associated with the tag ID 102 with reference to the notification target list 101.

  Further, as shown in FIG. 5, the ECU 20 has a detection frequency list 110 in which identification information of the RF tag 51 is registered. In the detection count list 110, identification information of the RF tag 51, information on the monitored object 50, and information on the presence or absence of a sensor are registered in association with each other. The detection count list 110 includes, for example, a tag ID 102, a monitoring target object name 111, a detection count N112, and a sensor presence / absence 113. The monitored object name 111 is configured of, for example, a wallet, a game device, and the like. The number of times of detection N112 is the number of times of detection of the corresponding monitored object 50. The sensor presence / absence 113 indicates whether the RF tag 51 has the sensor 54 or not. The detection number list 110 is stored in a memory (not shown) in the ECU 20, and when the RF tag 51 is detected, any one of the tag ID 102, the monitoring object name 111, the detection number N112, and the sensor presence / absence 113 is registered (or Updated).

  The detection unit 30 is a device which is mounted on the vehicle 2 and detects the getting off of the passenger in the vehicle 2. The detecting unit 30 may have any configuration as long as it can detect the getting off of the passenger in the vehicle 2. For example, the detection unit 30 may detect that the ignition switch (not shown) is off, or detect that the position of the shift switch (not shown) is P (parking). Good. The detection unit 30 may also detect a state of a door curtain switch that is turned on / off according to the opening / closing of a door (not shown) of the vehicle 2 or turns on when the seat belt of the seat 3 is removed. The state of the seat belt switch may be detected. The detection unit 30 may be a combination of these.

  The notification unit 40 is mounted on the vehicle 2 and notifies the passenger in the compartment 201 by a plurality of methods. The notification unit 40 performs a notification operation in response to a control signal from the ECU 20. The notification unit 40 includes a display 41 and a speaker 42. The display 41 is, for example, a liquid crystal display device, and is disposed on an instrument panel (not shown) or an AV console (not shown) of the vehicle 2 or the like. The speaker 42 is, for example, a speaker of on-vehicle audio, but may be a horn or the like. The informing unit 40 notifies the passenger in the passenger compartment 201 of the fact that the monitored object 50 is left behind by displaying a warning image on the display 41 or sounding a warning sound from the speaker 42. . When the display 41 has a touch panel, the notification unit 40 cancels the display of a warning image and the output of a warning sound according to an operation from the passenger on the touch panel.

  The wireless communication unit 60 is mounted on the vehicle 2 and performs wireless communication with the portable terminal 5 registered in advance using a plurality of communication methods. The wireless communication unit 60 performs wireless communication with the portable terminal 5 based on the information of the portable terminal 5 corresponding to the identification information of the RF tag 51 registered in the notification target list 101. Therefore, when the information of the plurality of mobile terminals 5 is registered in the notification target list 101, the plurality of mobile terminals 5 become the notification targets. The wireless communication unit 60 has a first communication unit 61 and a second communication unit 62, as shown in FIG.

  Among the plurality of communication methods, the first communication unit 61 performs wireless communication based on the first wireless communication method for establishing wireless communication when the portable terminal 5 is in the communication area. The first communication method is, for example, near field communication such as Bluetooth (registered trademark) or WiFi (registered trademark). The first communication unit 61 automatically establishes (links) wireless communication with the portable terminal 5 located in the communication area of the first wireless communication method by the first wireless communication method. The first communication unit 61 transmits a notification signal to the portable terminal 5 when the above-described notification condition is satisfied. The notification signal is, for example, an electronic mail in the electronic mail function, and a notification in the communication application. The first communication unit 61 includes an antenna unit 63, and transmits and receives radio waves to and from the portable terminal 5 via the antenna unit 63.

  The second communication unit 62 performs wireless communication based on a second wireless communication method in which the communication area is wider than that of the first wireless communication method. The second communication method is, for example, LTE (Long Term Evolution) or the like, and is used on the public network 6. If the wireless communication between the first communication unit 61 and the portable terminal 5 is not established, the second communication unit 62 establishes the wireless communication with the portable terminal 5. The case where the wireless communication between the first communication unit 61 and the portable terminal 5 is not established means, for example, the case where the portable terminal 5 exists outside the communication area of the first wireless communication method. The second communication unit 62 transmits a notification signal to the portable terminal 5 after wireless communication with the portable terminal 5 is established. The second communication unit 62 includes an antenna unit 64, and transmits and receives radio waves to and from the public network 6 via the antenna unit 64. The ECU 20 of the present embodiment performs a notification process between the first communication unit 61 and the portable terminal 5 when the above-described notification condition is satisfied. On the other hand, when the wireless communication between the first communication unit 61 and the portable terminal 5 is not established, the wireless communication between the second communication unit 62 and the portable terminal 5 is established and the notification process is performed.

  Next, registration of the notification object list 101 of the on-vehicle monitoring device 1 according to the present embodiment will be described with reference to FIG.

  In FIG. 6, a PC 9 is, for example, a personal computer installed at the passenger's home 8. The PC 9 is connected to a reader unit 10 installed at home 8. The PC 9 is connected to the public network 6 and performs wireless communication with the vehicle 2 via the public network 6. The PC 9 can perform wireless communication with the first communication unit 61 or the second communication unit 62 of the wireless communication unit 60.

  The reader unit 10 wirelessly communicates with the RF tag 51 and receives identification information from the RF tag 51. The PC 9 registers the identification information of the RF tag 51 received by the reader unit 10 in the notification target list 101. The tag ID 102 of the RF tag 51 is registered in the notification target list 101.

  For example, the PC 9 registers the telephone number 103, the MAC address 104, and the BD address 105 input from the passenger in the notification target list 101 in association with the tag ID 102. When the registration is completed, the PC 9 transmits the notification target list 101 to the vehicle 2 via the public network 6. The ECU 20 stores the notification target list 101 received by the wireless communication unit 60 in a memory (not shown) or the like. When the notification target list 101 is already stored in the memory, the ECU 20 updates the notification target list 101 with the received notification target list 101.

  Next, the detection operation of the RF tag 51 and the notification operation to the portable terminal 5 in the on-vehicle monitoring device 1 according to the present embodiment will be described with reference to FIG.

  In FIG. 7, in step S <b> 10, the ECU 20 performs detection processing of the RF tag 51. Details of step S10 will be described later. At this time, as described above, it is assumed that the first communication unit 61 establishes (links) wireless communication in advance for the portable terminal 5 in the communication area of the first wireless communication method.

  Next, in step S11, the ECU 20 determines whether the passenger has got off. The ECU 20 causes the detection unit 30 to detect the getting off of the passenger by the above-described method. If a passenger's getting off is detected, the process proceeds to step S12. On the other hand, when the passenger's getting off is not detected, the process returns to step S10.

  In step S12, the ECU 20 specifies the state of the monitored object 50 based on the identification information of the RF tag 51. For example, when the reader unit 10 receives identification information from the RF tag 51, the ECU 20 specifies that the monitoring target object 50 holding the RF tag 51 is present in the passenger compartment 201.

  Next, in step S13, the ECU 20 determines whether notification is necessary. In step S13, assuming that, for example, the passenger notices that the monitored object 50 brought into the compartment 201 has been misplaced, and performs a predetermined operation on the notification unit 40 and the like, the ECU 20 performs, for example, notification It is determined whether the part 40 has performed a predetermined operation or the like. If it is determined that the notification is necessary, the process proceeds to step S14. On the other hand, when it is determined that the notification is not necessary, the present process ends.

  In step S14, the ECU 20 performs notification processing. In step S14, three stages of notification processing are performed. That is, as a first step, the ECU 20 controls the notification unit 40 and performs notification processing by the display 41 and the speaker 42 described above. If a response is not obtained for the notification process (NO in step S15), the ECU 20 performs a notification process between the first communication unit 61 and the portable terminal 5 as a second step. For example, when a response is not obtained for this notification process (NO in step S15), the ECU 20 establishes, as a third step, wireless communication between the second communication unit 62 and the portable terminal 5 and gives notification. Do the processing.

  In step S15, the ECU 20 determines whether there is a response to the notification. For example, when a predetermined operation is performed on the notification unit 40, the ECU 20 determines that there is a response, and ends the present process. On the other hand, when there is no response, it returns to step S14. Further, for example, when the wireless communication unit 60 receives an e-mail or the like from the portable terminal 5, the ECU 20 determines that there is a response, and terminates the present process.

  Next, the detection process of the RF tag 51 in step 10 of FIG. 7 will be described with reference to FIG.

  In FIG. 8, in step S20, the ECU 20 acquires the tag ID 102 from the fixed area of the frame. The ECU 20 controls the reader unit 10 to periodically emit radio waves to the radio wave radiation range 12 in the passenger compartment 201, and receives data including the tag ID 102 from the RF tag 51. The ECU 20 acquires the tag ID 102 from the fixed area in the frame of the data received by the reader unit 10.

  Next, in step S21, the ECU 20 collates with the notification target list 101. The ECU 20 reads the notification target list 101 from the memory or the like, and collates it with the tag ID 102 acquired in step S20.

  Next, in step S22, the ECU 20 determines whether the tag ID 102 acquired in step S20 is registered in the notification target list 101. If it is determined that it is not registered, the process proceeds to step S27, the ECU 20 discards the acquired tag ID 102, and ends (returns) this process. On the other hand, if it is determined that it is registered, the process proceeds to step S23.

  In step S23, the ECU 20 collates with the detection number list 110. The ECU 20 reads the detection number list 110 from the memory or the like, and collates it with the tag ID 102 acquired in step S20.

  Next, in step S24, the ECU 20 determines whether or not the tag ID 102 acquired in step S20 is registered in the detection count list 110. If it is determined that it is not registered, the process proceeds to step S28, while if it is determined that it is registered, the process proceeds to step S25.

  In step S25, the ECU 20 adds 1 to the number of detections N112 in the detection number list 110, and proceeds to step S25.

  Next, in step S26, the ECU 20 acquires data from the user area in the frame of the data received by the reader unit 10, and ends (returns) this process. The data acquired from the user area is, for example, various kinds of information stored in the memory 53 of the RF tag 51, and includes the above-described monitored object name 111, sensor presence / absence 113, and the like.

  In step S28, the ECU 20 registers the tag ID 102 acquired in step S20 in the detection count list 110.

  Next, in step S29, the ECU 20 sets the detection count N112 corresponding to the tag ID 102 registered in the detection count list 110 to 0, and proceeds to step S26. In step S26, the ECU 20 registers (or updates) one of the monitoring object name 111 and the sensor presence / absence 113 corresponding to the tag ID 102 registered in the detection count list 110 in the detection count list 110, and this processing is performed. Finish. That is, when the registration is performed anew, all items are registered, and when the registration is already performed, the number of times of detection N112 is updated.

  As described above, the on-vehicle monitoring device 1 according to the present embodiment includes the reader unit 10, the detection unit 30, the wireless communication unit 60, and the ECU 20. The reader unit 10 radiates a radio wave into the compartment 201 and receives identification information of the RF tag 51 from the RF tag 51 held by the monitored object 50 in the compartment 201. As a result, it is possible to easily manage the monitoring target 50 by specifying an object (the monitoring target 50) to be brought into the compartment 201. The detection unit 30 detects the getting-off of the passenger in the passenger compartment 201, so that the state of the passenger in the passenger compartment 201 can be easily grasped. The wireless communication unit 60 establishes a wireless communication based on the first wireless communication method of establishing wireless communication when the portable terminal 5 is in the communication area, and a communication area is larger than that of the first wireless communication method. The second communication unit 62 performs wireless communication based on a wide second wireless communication scheme, and performs wireless communication with the mobile terminal 5 registered in advance. Thus, wireless communication with the portable terminal 5 can be reliably performed using a plurality of communication methods. When the notification condition is satisfied, the ECU 20 performs notification processing for controlling the wireless communication unit 60 so as to transmit a notification signal for notifying the notification means of the portable terminal 5. The ECU 20 performs a notification process when the notification condition is satisfied, and if the wireless communication between the first communication unit 61 and the portable terminal 5 is not established, the ECU 20 performs a communication process between the second communication unit 62 and the portable terminal 5. Radio communication is established and notification processing is performed. Thereby, when the passenger is near the vehicle 2, the mobile terminal 5 can be notified promptly by short distance wireless communication, and the communication area is wide even if the passenger moves away from the vehicle 2 The mobile terminal 5 can be reliably notified by the proper wireless communication method.

  Further, in the on-vehicle monitoring device 1 according to the present embodiment, the ECU 20 has the notification target list 101 in which the identification information of the RF tag 51 is registered. The ECU 20 determines whether or not the identification information of the RF tag 51 received by the reader unit 10 is registered in the notification target list 101, which satisfies the notification condition. When registered in the notification target list 101, the notification processing is performed, and when not registered in the notification target list 101, the notification processing is not performed. Thereby, only the monitoring target object 50 corresponding to the RF tag 51 registered in the notification target list 101 can be monitored.
