And various interfaces (I / F) 15, 16, 17, 18. The control unit 11 executes a control program stored in the ROM 12 and controls the vehicle-mounted device 10 as a whole.

  The ROM 12 stores audio data and the like to be described later in addition to the control program. The RAM 13 is used as a work memory for the control unit 11. The wireless module 14 (communication unit) is wirelessly connected to the vehicle management device 30 and transmits and receives data. The timer 24 measures elapsed time and the like.

  The camera I / F 15 is connected to a camera 19 that is installed in the management vehicle 40 and captures the front of the vehicle including the white line of the road on which the vehicle is traveling. As will be described later, the image taken by the camera 19 is used to determine whether or not the vehicle deviates from the white line. That is, the camera I / F 15 functions as a white line departure detection unit that acquires information for identifying whether or not the vehicle deviates from the white line of the road on which the vehicle is traveling. A G sensor 20 that detects the acceleration of the vehicle as a G value is connected to the sensor I / F 16. That is, the sensor I / F 16 functions as an acceleration detection unit that acquires information for calculating the acceleration of the vehicle. A speed sensor 21 that detects the vehicle speed is connected to the speed I / F 17. The I / O interface 18 is connected to a speaker 22 (voice output unit) that outputs a confirmation voice or the like from the management office 70 side.

  A microphone 23 (voice input unit) is connected to the voice recognition unit 25. The voice recognition unit 25 recognizes and encodes the voice input from the microphone 23, and outputs the encoded voice data to the control unit 11.

  On the other hand, a vehicle management apparatus 30 disposed in a management office 70 outside the vehicle includes a speaker 36 and a microphone connected via a control unit 31, a display 32, a wireless module 34, an operation unit 35, and an I / O interface 39. 37. The control unit 31 controls the entire vehicle management device 30 according to a control program stored in a built-in ROM.

  The display 32 (display unit) displays various information such as a safety confirmation status on the screen. The wireless module 34 (transmitting unit and receiving unit) is wirelessly connected to the vehicle-mounted device 10 and transmits and receives data. The operation unit 35 has a pointing device such as a keyboard and a mouse, and receives an instruction operated by an administrator. The speaker 36 emits a sound such as a warning.

  Operation | movement of the condition confirmation system 1 which has the said structure is shown. For example, when an earthquake, heavy rain, fire, or the like occurs in the jurisdiction, the safety confirmation operation is performed on all the vehicles at once.

  FIG. 3 is a flowchart showing an operation procedure of the vehicle-mounted device 10. This operation program is stored in the ROM 12 and is executed by the control unit 11.

  First, the vehicle-mounted device 10 waits until a safety confirmation instruction (an opportunity signal) is received from the vehicle management device 30 installed in the management office 70 (step S1). When the safety confirmation instruction is received, the in-vehicle device 10 follows the safety confirmation instruction, for example, a confirmation voice saying “Safety confirmation. If it is all right, say okay. If you need help, please say help.” And output from the speaker 22 (step S2).

  Thereafter, the vehicle-mounted device 10 performs voice recognition on the voice input from the microphone 23 (step S3). As a result of the voice recognition, the vehicle-mounted device 10 determines whether or not the occupant of the management vehicle 40 has said “OK” (first response voice), which is a positive voice, as a response to the safety confirmation (step S4). When it is determined that “OK” is said, the vehicle-mounted device 10 transmits a signal (first signal) indicating “OK” to the vehicle management device 30 on the management office 70 side (step S5). Thereafter, the vehicle-mounted device 10 ends this operation.

  On the other hand, if it is not determined that “OK” in step S4, the vehicle-mounted device 10 causes the occupant of the management vehicle 40 to “help”, which is a negative voice as a response to the safety confirmation (second answer voice). Is determined (step S6). If it is determined that the word “help” has been said, the vehicle-mounted device 10 transmits a signal (second signal) indicating “help” to the vehicle management device 30 on the management office 70 side (step S7). Thereafter, the vehicle-mounted device 10 ends this operation.

  On the other hand, if it is not determined in step S6 that “help”, the vehicle-mounted device 10 determines whether or not there is no response for a predetermined time (for example, 10 seconds) (step S8). . The predetermined time can be arbitrarily set. If the voice is received before the predetermined time has elapsed, the vehicle-mounted device 10 returns to the process of step S3 again and waits until voice is input from the microphone 23 and voice recognition is performed.

  On the other hand, when the predetermined time has elapsed in step S8, the vehicle-mounted device 10 transmits a signal (third signal) indicating that there is no response to the vehicle management device 30 on the management office 70 side (step S9). Thereafter, the vehicle-mounted device 10 ends this operation.

  FIG. 4 is a flowchart showing an operation procedure of the vehicle management device 30. When performing safety confirmation, the vehicle management apparatus 30 first sends safety confirmation instructions to all the management vehicles 40 (in the present embodiment, four vehicles a, b, c, and d) simultaneously via the wireless module 34. Transmit (step S11).

  The vehicle management device 30 waits until a reply signal is received from the vehicle-mounted device 10 (step S12). When the reply signal is received, the safety confirmation status is displayed on the screen of the display 32 based on the reply signal (step S13). FIG. 5 is a diagram showing a screen of the display 32 on which the safety confirmation status is displayed. On this safety confirmation status screen, the status of each passenger in each vehicle is displayed as a character string “OK”, “Help”, and “No response”. As a result, the manager on the management office 70 side can detect the status of all the occupants in a list, and can immediately perform rescue and other actions. Note that this safety confirmation status screen is an example.

  Subsequently, the vehicle management device 30 determines whether or not the safety confirmation of all the vehicles has been completed (step S14). When there is an unconfirmed vehicle, the vehicle management apparatus 30 returns to the process of step S12. On the other hand, when the safety confirmation of all the vehicles is completed, the vehicle management device 30 ends this operation.

  FIG. 6 is a diagram illustrating a scenario when the safety confirmation operation is performed. When the manager E who operates the vehicle management device 30 installed in the management office 70 performs the safety confirmation operation on the crew members A, B, and C boarding the respective management vehicles 40 all at once, From the speaker 22 of the vehicle-mounted device 10 installed, “Ping Pong! It is safety confirmation. If it ’s okay, say yes. If not, please say "Please help me".

  In the example of FIG. 6, a case is shown in which occupant A replied “It's okay”, occupant B is silent, and occupant C replied “please help me”. On the screen of the display 32 of the vehicle management device 30, character strings “Mr. A is okay”, “Mr. B is unconfirmed”, and “Mr. C needs help” are displayed in a list.

  As a result, the manager E can send a rescue to the management vehicle 40 on which Mr. C, who has replied that help is needed, is on board. In addition, rescue can also be directed to the management vehicle 40 on which Mr. B who has not responded and has not been confirmed is boarding.

  As described above, according to the situation confirmation system 1 including the on-vehicle device 10 according to the first embodiment, on the management office 70 side that manages each management vehicle 40, the on-vehicle device mounted on each management vehicle 40. The status of the occupant of each managed vehicle 40 can be confirmed by the type of signal received by the vehicle management device 30 from 10. That is, at the management office 70 side, when the vehicle management device 30 receives the first signal indicating “OK”, the occupant is identified as safe, and the second signal indicating “help” is received. If there is a problem, it can be identified that there is a possibility that an abnormality has occurred in the occupant or the vehicle. Further, when there is no response from the occupant and a third signal indicating that there is no response is received, it can be identified that there is a possibility that an abnormality has occurred in the occupant or the vehicle. Thereby, on the management office 70 side, it is possible to quickly confirm the state of the occupant. Further, the occupant can respond to the predetermined confirmation voice output from the vehicle-mounted device 10 only by replying the first reply voice “OK” or the second reply voice “Help”. Can be transmitted to the management office 70 side. In addition, even when the occupant cannot reply to the confirmation voice output from the vehicle-mounted device 10, the occupant can transmit the current situation to the management office 70 side.

  In the above embodiment, the safety confirmation operation is shown as an example. However, the present invention is not limited to this, and the situation confirmation system 1 can be applied to other confirmation operations. For example, when applied to the call check operation, a confirmation voice “Ping Pong! Call me. Please say your name” is output from the speaker 22 of the vehicle-mounted device 10, and the passenger presses the call button, Or, “A (name)” is replied without pressing. The vehicle management device 30 recognizes the voice and displays the character string “Mr. A's call OK” on the screen of the display 32.

  Moreover, it is applicable also to sleep time confirmation operation | movement. A confirmation voice “Ping Pong! How many hours did you sleep?” Is output from the speaker 22 of the vehicle-mounted device 10, and the occupant answers “It is 8 hours.” The vehicle management device 30 recognizes the voice and displays a character string “Mr. A sleep time OK” on the screen of the display 32. Note that the sleep time confirmation operation may be performed together with the call operation.

  It can also be applied to continuous operation time confirmation operation. A confirmation sound “Ping Pong! Are you waking up?” Is output from the speaker 22 of the vehicle-mounted device 10, and the occupant answers “Wake up.” At this time, if there is no response from the passenger, the above operation is repeated. When a positive response such as “Wake up”, “No problem”, or “OK” is received from the passenger, the management office 70 side says to the speaker 22 “Please continue to drive carefully” The voice may be output and a dialogue may be performed. In addition, if there is a negative response from the passenger such as “I am sleepy”, “I am sleepy”, “I want to take a break”, the management office 70 side says “I understand. Let's take a break” to the speaker 22. A voice may be output and a dialogue may be performed.

  In addition, the situation confirmation system 1 is also effective when performing business communication, emergency evacuation communication, or the like.

(Second Embodiment)
In 2nd Embodiment, when the G sensor 20 mounted in the onboard equipment 10 detects the impact added to the management vehicle 40, the example which confirms a passenger | crew's condition is shown.

  Moreover, the onboard equipment of 2nd Embodiment has a structure substantially the same as 1st Embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  FIG. 7 is a flowchart showing an operation procedure of the vehicle-mounted device 10 according to the second embodiment. After the power is turned on, the vehicle-mounted device 10 first measures acceleration by the G sensor 20 (step S21). The vehicle-mounted device 10 determines whether or not the measured acceleration exceeds a preset threshold value (step S22). This threshold value is set in advance based on the magnitude of the G value (acceleration) when the management vehicle 40 receives an impact due to a collision or the like. When the threshold value is not exceeded, the vehicle-mounted device 10 returns to the process of step S21.

  On the other hand, when the acceleration measured in step S21 exceeds the threshold value, the vehicle-mounted device 10 says “If it is all right, it is all right.” From the speaker 22 based on the sound data registered in the ROM 12 in advance. A confirmation voice saying "Please help me if necessary" is output (step S23).

Thereafter, the vehicle-mounted device 10 performs voice recognition on the voice input from the microphone 23 (step S24). As a result of the voice recognition, the vehicle-mounted device 10 determines whether or not the occupant of the management vehicle 40 has said “OK”, which is a positive response (step S25). If it is determined that “it is ok”, the vehicle-mounted device 10 outputs a message “Please drive carefully” from the speaker 22 (step S26). This message is registered in advance in the ROM 12 as voice data. Thereafter, the vehicle-mounted device 10 ends this operation.
At this time, the in-vehicle device 10 may transmit a signal (first signal) indicating “OK” to the vehicle management device 30 on the management office 70 side in addition to the output of the message.

  On the other hand, if it is not determined that “OK” in step S4, the vehicle-mounted device 10 determines whether or not the occupant of the management vehicle 40 has said “help”, which is a negative response (step S27). . If it is determined that the word “help” has been said, the vehicle-mounted device 10 transmits a signal (second signal) representing “help” to the vehicle management device 30 on the management office 70 side via the wireless module 14 ( Step S28). Thereafter, the vehicle-mounted device 10 ends this operation.

  On the other hand, if it is not determined in step S27 that “help”, the vehicle-mounted device 10 determines whether or not there is no response for a predetermined time (for example, 10 seconds) (step S29). . The predetermined time can be arbitrarily set. When the voice is received before the predetermined time has elapsed, the vehicle-mounted device 10 returns to the process of step S24 again and waits until the voice is input from the microphone 23 and voice recognition is performed.

  When the predetermined time has elapsed in step S29, the vehicle-mounted device 10 transmits a signal (third signal) indicating that there is no response to the vehicle management device 30 on the management office 70 side via the wireless module 14 ( Step S30). Thereafter, the vehicle-mounted device 10 ends this operation.

  When a signal indicating “help” is transmitted to the vehicle management device 30 on the management office 70 side, or when a signal indicating no response is transmitted in step S30, the vehicle The management device 30 determines that a trouble has occurred in the management vehicle 40 and displays a screen prompting a rescue request on the display 32.

  FIG. 8 is a diagram showing a screen prompting a rescue request displayed on the display 32. On this screen, characters of “rescue request”, “abnormality has occurred in the following vehicle, please confirm and rescue immediately” and “vehicle a occupant A” are displayed. This screen is an example.

  According to the vehicle-mounted device according to the second embodiment, when an impact is applied to the management vehicle 40 during driving, the occupant's situation can be quickly confirmed by voice. In addition, when an impact is detected, the situation is confirmed on the vehicle-mounted device 10 side without depending on the instruction from the management office 70 side. Therefore, if there is no problem, the management office 70 notifies the situation. Can be omitted. On the other hand, if a problem occurs, it can be promptly dealt with.

(Third embodiment)
In the third embodiment, an example is shown in which the occupant's situation is confirmed when the deviation of the white line on the road is detected using the camera 19 mounted on the vehicle-mounted device 10.

  The vehicle-mounted device of the third embodiment has almost the same configuration as that of the first embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  FIG. 9 is a flowchart showing an operation procedure of the vehicle-mounted device 10 according to the third embodiment. The vehicle-mounted device 10 performs image recognition processing on the image ahead of the vehicle photographed by the camera 19, and confirms the presence and position of a white line on the road (step S41).

  The vehicle-mounted device 10 determines whether or not the management vehicle 40 has deviated from the white line based on the presence and position of the white line (step S42). When not deviating, the onboard equipment 10 returns to the process of step S41. If it is determined that the white line does not completely deviate but may deviate, the process may proceed to step S43.

  When the vehicle deviates from the white line, the in-vehicle device 10 says “If it is all right, it is all right from the speaker 22 based on the voice data registered in the ROM 12 in advance, as in the second embodiment. A confirmation voice saying "Please help if you need help" is output (step S43). Since the processing after step S43 is the same as the processing after step S23 of the second embodiment, the description thereof is omitted.

  According to the vehicle-mounted device 10 according to the third embodiment, when a situation that deviates from the white line occurs, the state of the occupant can be quickly confirmed by voice. In addition, when the occurrence of a situation that deviates from the white line is detected, the situation is checked on the vehicle-mounted device 10 side without depending on the instruction from the management office 70 side. Can omit from the management office. On the other hand, if a problem occurs, it can be promptly dealt with.

  In particular, a situation that deviates from the white line may be, for example, a case where the vehicle deviates from the white line on an expressway and a vehicle falls from the road. In this case, there are many cases where the passenger is not in a situation where the management office 70 can be contacted by telephone or email.
