  FIG. 3 is a schematic diagram showing a schematic configuration of the leaving correspondence control device 2.

  The leaving correspondence control device 2 includes an input unit 21, an output unit 22, a storage unit 23, and a calculation unit 24. The leaving correspondence control device 2 is mounted on the vehicle 1 as an ECU.

  The input unit 21 is a circuit that receives a sensor signal from the sensor 3. The input unit 21 supplies the received sensor signal to the calculation unit 24.

  The output unit 22 is a circuit that transmits data to the vehicle control device 5. The output unit 22 transmits data to the vehicle control device 5 based on the control signal supplied from the calculation unit 24.

  The storage unit 23 is a nonvolatile memory that stores information. The storage unit 23 stores a reference value for determining whether or not a person has been left in the vehicle compartment based on the received sensor signal. Further, the storage unit 23 stores data used for processing executed by the calculation unit 24.

  The operation unit 24 performs an operation based on the signal supplied from the input unit 21 and outputs today to the output unit 22. The operation unit 24 has a processor that executes an operation by executing a predetermined program.

  The calculation unit 24 includes a leaving detection unit 241, a control content determination unit 242, and a clock unit 243. Each of these units included in the arithmetic unit 24 is a functional module implemented by a program executed on a processor included in the arithmetic unit 24. Alternatively, these units included in the arithmetic unit 24 may be realized by a dedicated circuit.

  The leaving detection unit 241 detects the leaving of the person in the vehicle compartment based on a sensor signal provided by the sensor 3 provided in the vehicle compartment of the vehicle 1 for detecting a person present in the vehicle compartment.

  The abandonment detection unit 241 detects that the abandonment has occurred when all the sensor signals of the seat sensor 3a, the in-vehicle camera 3b, and the human sensor 3c included in the sensor 3 correspond to the presence of a person. On the other hand, the abandonment detection unit 241 detects that the abandonment has occurred when any of the sensor signals of the sitting sensor 3a, the in-vehicle camera 3b, or the human sensor 3c included in the sensor 3 corresponds to the presence of a person. You may.

  When abandonment is detected, the control content determination unit 242 determines the content of control on the vehicle corresponding to the abandonment according to the current position.

  The clock unit 243 measures the current time.

  FIG. 4 is a processing flowchart of the leaving correspondence control device 2.

  First, the leaving detection unit 241 receives, via the input unit 21, a sensor signal from the sensor 3 provided in the vehicle compartment of the vehicle 1 for detecting a person existing in the vehicle compartment. Then, the leaving detection unit 241 determines whether or not the leaving of the person in the vehicle compartment is detected based on the received sensor signal (step S11). When it is determined that the abandonment has not been detected (step S11: N), the abandonment detection unit 241 ends the process.

  When it is determined that the leaving has been detected (step S11: Y), the calculation unit 24 acquires the position of the vehicle 1 via the GPS receiver 4 (step S12).

  Next, the control content determination unit 242 determines whether the current time measured by the clock unit 243 is noon (step S13). The control content determination unit 242 determines that the current time is daytime when the current time is included in a time range (for example, 6:00 to 18:00) set as a daytime time zone. Further, the control content determination unit 242 may acquire the sunrise time and the sunset time of the current location, and may determine that the current time is daytime when the current time is included between the sunrise time and the sunset time.

If the current time is determined to be the daytime (step S13: Y), the control content determining section 242, the hold time is set to hold time T _D for daytime (step S14). The suspension time is the time from when the content of the control corresponding to leaving is determined to when the content of the control is executed.

If the current time is judged not a day (step S13: N), the control content determining section 242, the hold time is set to holding time T _N for a long night than hold time T _D for daytime (step S15 ).

  By changing the suspension time according to the current time, the abandonment control device 2 can control the vehicle 1 corresponding to the abandonment at an appropriate timing according to the current time.

  In addition, by setting the holding time for the night longer than the holding time for the day, the abandonment handling control device 2 can reduce the influence on the surroundings of the vehicle 1 due to the execution of the control corresponding to the abandonment. For example, the control content determination unit 242 determines “reporting to a public organization” and “ringing of a horn” as control to the vehicle 1 corresponding to leaving, and the vehicle 1 immediately notifies the public organization. Assume that the horn 10 is sounded after the hold time. If the horn 10 rings immediately before the public organization receiving the report responds, the people around the vehicle 1 that heard the horn 10 will not actually participate in the response. That is, even if the horn sounds, the effect may not be obtained. On the other hand, when the current time is night, since the surroundings of the vehicle 1 are quieter than daytime, the sound of the horn 10 is louder than in daytime. Therefore, by setting the night holding time longer than the day holding time, the abandonment-response control device 2 can limit the influence on the surroundings of the vehicle due to execution of control such as, for example, sounding of a horn.

  Next, the control content determination unit 242 determines the content of the control on the vehicle 1 corresponding to leaving, according to the position of the vehicle 1 (step S16), and ends the process.

  The leaving correspondence control device 2 repeatedly executes the series of processes described above at predetermined time intervals.

  FIG. 5 is a flowchart of the control content determination process.

  First, the control content determination unit 242 determines the control content including “lighting of the hazard lamp” or “report to the vehicle owner” (step S21).

  “Hazard lamp lighting” is control for lighting the hazard lamp 8. The lighting of the hazard lamp 8 allows a person in the vicinity of the vehicle 1 to recognize the possibility that some problem has occurred in the vehicle 1.

  The “report to the vehicle owner” is control for causing the communication module 9 to call the telephone number stored in the storage unit 23 as the telephone number of the vehicle owner. When the vehicle owner receives a call from the communication module 9, the leaving correspondence control device 2 transmits a voice message stored in the storage unit 23 in advance. By listening to the voice message, the vehicle owner can recognize that a person has been left behind in the vehicle 1.

  It is desirable that the “lighting of the hazard lamp” and the “notification to the vehicle owner” be executed regardless of the position of the vehicle 1 in order to cope with leaving. By determining the control contents including these two, the abandonment control device 2 can reliably execute the control corresponding to the abandonment.

  Next, the control content determining unit 242 determines whether the position of the vehicle 1 is included in the dangerous area (Step S22). The storage unit 23 stores in advance a crime occurrence frequency map in which the crime occurrence frequency is associated with each area. The area is a predetermined geographical range, and is, for example, a unit of a town crest in each municipality. The dangerous area is an area where the crime occurrence frequency is larger than a crime frequency threshold (for example, 100 cases per year) in the crime occurrence frequency map. Further, the control content determination unit 242 is connected to the network via the communication module 9, transmits the position of the vehicle 1 to an information server (not shown) that stores a crime occurrence frequency map, and the position of the vehicle 1 is dangerous from the information server. An answer as to whether or not the area is included may be obtained.

  When determining that the position of the vehicle 1 is included in the danger area (step S22: Y), the control content determination unit 242 determines that the window is closed, the door is locked, the horn sounds, or the public The contents of the control including "notification" are determined (step S23), and the process ends.

  By the processing in step S23, the control content determination unit 242 determines the content of the control as “lighting of the hazard lamp”, “report to the vehicle owner”, “window closed”, “door lock”, “horn sound”, and , "Notify public authorities". In addition, the control content determination unit 242 determines the content of the control as at least one of “lighting of the hazard lamp” or “report to the vehicle owner”, and “window closing”, “door lock”, “ It may be determined to be at least one of "horn sounding" and "report to public authorities".

  “Window closing” is control for closing the window 7. The vehicle 1 that has been controlled to “close the window” while the window 7 is closed keeps the window 7 closed. By closing the window 7, the control content determination unit 242 can prevent a suspicious person from entering the cabin of the vehicle 1 in the danger area, and maintain the safety of persons in the cabin.

  “Door lock locking” is control for locking the door lock 6. The vehicle 1 that has been controlled by the “door lock locking” while the door lock 6 is locked keeps the door lock 6 locked. By locking the door lock 6, the control content determination unit 242 can prevent a suspicious individual from entering the cabin of the vehicle 1 in the dangerous area, and maintain the safety of persons in the cabin.

  “Ring of horn” is control to make horn 10 ring. The sound of the horn 10 allows the control content determination unit 242 to call attention of the surrounding people.

  The “report to public organization” is a control to make the communication module 9 call the telephone number stored in the storage unit 23 as the telephone number of the public organization. The public institution is a public institution capable of responding to leaving a person in the vehicle compartment, such as a police or fire department emergency center. The storage unit 23 stores location information and telephone numbers in association with each other for each public institution. The control content determination unit 242 specifies the nearest public institution based on the position information of the vehicle 1 and causes the communication module 9 to call the telephone number of the specified public institution. When a person in charge of the public organization receives a call from the communication module 9, the leaving correspondence control device 2 transmits a voice message stored in the storage unit 23 in advance. By hearing the voice message, the person in charge of the public organization can recognize that a person has been left behind in the cabin of the vehicle 1.

  In a dangerous area, there is a risk that a person left in the vehicle compartment will be involved in a crime, so it is necessary to ensure safety and take immediate action against the abandonment. By determining the control content as described above, the abandonment control device 2 can control the vehicle 1 suitable for the position of the vehicle 1 when the position of the vehicle 1 is included in the dangerous area.

  When determining that the position of the vehicle 1 is not included in the dangerous area (step S22: N), the control content determining unit 242 determines whether the position of the vehicle 1 is included in the downtown area (step S24). . The storage unit 23 stores in advance a commercial facility ratio map in which the ratio of the land area occupied by the commercial facilities is associated with each area. A commercial facility is a facility where a product is sold or a service is provided to a consumer, and is, for example, a shopping center, a supermarket, a drug store, a convenience store, a restaurant, and the like. The downtown area is an area where the ratio of the land area occupied by the commercial facility is larger than the downtown area threshold (for example, 80%) in the commercial facility ratio map. Further, the control content determining unit 242 is connected to the network via the communication module 9 and transmits the position of the vehicle 1 to an information server (not shown) that stores a commercial facility ratio map, and the position of the vehicle 1 is busy from the information server. An answer as to whether or not it is included in the city area may be obtained.

  When determining that the position of the vehicle 1 is not included in the downtown area (step S24: N), the control content determination unit 242 determines whether the position of the vehicle 1 is included in the range of the parking lot of the commercial facility. (Step S25). The storage unit 23 stores in advance a commercial facility parking map that specifies the range of the commercial facility parking lot. The control content determination unit 242 is connected to the network via the communication module 9 and transmits the position of the vehicle 1 to an information server (not shown) that stores a commercial facility parking lot map. An answer as to whether or not it is included in the parking lot of a commercial facility may be obtained.

  The control content determination unit 242 determines that the position of the vehicle 1 is included in the downtown area (step S24: Y), or determines that the position of the vehicle 1 is a parking lot of a commercial facility (step S25). : Y), determine the contents of control including "window closed", "door lock", "report to nearby stores", "ringing horn after elapse of hold time", or "report to public organization after elapse of hold time" (Step S26), and the process ends.

  By the processing in step S26, the control content determination unit 242 indicates the content of the control as “lighting of the hazard lamp”, “report to the vehicle owner”, “window closed”, “door lock”, “report to the nearby store”. , "Horn sounds after elapse of the hold time", and "report to public organization after elapse of the hold time". In addition, the control content determination unit 242 determines the content of the control as at least one of “lighting of the hazard lamp” or “report to the vehicle owner”, and “window closing”, “door lock”, “ It may be determined to be at least one of "report to a nearby store", "ring a horn after the hold time elapses", or "report to a public organization after the hold time elapses".

  "Window closing" and "door lock locking" are the same as the control added in step S23, and thus description thereof is omitted.

  The “report to the nearby store” is a control to make the communication module 9 call the number registered as the telephone number of the nearby store. The nearby store is a store located within a predetermined distance (for example, within 100 m) from the position of the vehicle 1. The storage unit 23 stores the location information and the telephone number in association with each store. The control content determination unit 242 specifies the nearest store based on the position information of the vehicle 1, and causes the communication module 9 to call the telephone number of the specified store. When a person in charge of the store receives a call from the communication module 9, the leaving correspondence control device 2 transmits a voice message stored in the storage unit 23 in advance. By listening to the voice message, the store clerk can recognize that a person has been left behind in the cabin of the vehicle 1. When it is determined that the position of the vehicle 1 is a parking lot of a commercial facility (Step S25: Y), the control content determination unit 242 may specify the commercial facility as a nearby store.

  The "horn sound after the hold time" and the "report to the public organization after the hold time elapse" are respectively set to the "horn sound after the hold time set in step S14 or S15 after the control content is determined. This is a control to execute "notify a public organization".

  In a downtown area or a parking lot of a commercial facility, a store is present in the vicinity, and it is assumed that there are traffic of customers visiting the store. Therefore, it is considered that the merit that a person left behind in the vehicle compartment with the window or door openable can escape outside the vehicle compartment is not greater than the risk that the person left behind is subject to a crime. . On the other hand, it is considered that a store clerk can cope with leaving the vehicle in the vehicle cabin, so requesting a nearby store to handle it is preferable for early rescue of the abandoned person. While it is not necessary to ring the horn 10 and report to a public organization while requesting a response from a nearby store, it is appropriate to suspend the execution of these for a predetermined time.

  When the control content determination unit 242 determines the control content as described above, the abandonment control device 2 is suitable for the position of the vehicle 1 when the position of the vehicle 1 is a downtown area or a parking lot of a commercial facility. Vehicle 1 can be controlled.

  When determining that the position of the vehicle 1 is not included in the parking lot of the commercial facility (Step S25: N), the control content determination unit 242 determines whether the position of the vehicle 1 is included in the residential area area (Step S25). Step S27). The storage unit 23 stores in advance a house ratio map in which the ratio of the land area occupied by the house is associated with each area. The residential area is an area where the ratio of the land area occupied by the house is larger than the residential land threshold (for example, 80%) in the house ratio map. The control content determining unit 242 is connected to the network via the communication module 9 and transmits information on the position of the vehicle 1 to an information server (not shown) that stores a house ratio map. An answer as to whether or not it is included in the residential area may be obtained.

  When it is determined that the position of the vehicle 1 is included in the residential area (step S27: Y), the control content determination unit 242 “opens the window after the elapse of the hold time”, “opens the door lock after the elapse of the hold time”, “ The control contents including "horn sound after the hold time elapses" or "report to the public organization after the hold time elapses" are determined (step S28), and the process is terminated.

  By the process of step S28, the control content determination unit 242 determines the content of the control as “lighting of the hazard lamp”, “notification to the vehicle owner”, “window opening after the elapse of the hold time”, and “door open after the elapse of the hold time”. The lock is determined to be six, that is, a "horn sounds after the elapse of the hold time", and a "report to a public organization after the elapse of the hold time". In addition, the control content determination unit 242 determines the content of the control as at least one of “lighting of a hazard lamp” or “notification to the vehicle owner”, “window opening after elapse of the hold time”, “hold time” It may be determined to be at least one of "door lock unlocked after elapse", "horn sounds after elapse of hold time", or "report to public organization after elapse of hold time".

  "Ringing the horn after the elapse of the hold time" and "notifying the public organization after the elapse of the hold time" are the same as the control added in step S26, and thus the description is omitted.

  "Open window after elapse of hold time" is control for opening window 7 after elapse of the hold time set in step S14 or step S15 after the control content is determined. When the window 7 is opened, the control content determination unit 242 communicates the interior of the vehicle with the outside of the vehicle, and facilitates a rescue request by a voice of a person left behind. However, since there is a certain level of risk that the abandoned person becomes a crime target outside the vehicle compartment even in the residential area, the control content determination unit 242 controls the execution to be suspended until the suspension time elapses.

  The “door lock unlocking after elapse of hold time” is control for unlocking the door lock 6 after elapse of the hold time set in step S14 or step S15 after the control content is determined. When the door lock 6 is unlocked, the control content determination unit 242 enables the abandoned person to escape from the vehicle compartment. Since there is the same risk as the opening of the window 7, the control content determination unit 242 controls to suspend the execution until the suspension time elapses.

  When the control content determination unit 242 determines the control content as described above, the abandonment-response control device 2 performs control of the vehicle 1 suitable for the position of the vehicle 1 when the position of the vehicle 1 is included in the residential area. It can be performed.

  If the control content determination unit 242 determines that the position of the vehicle 1 is not included in the residential area (step S27: N), the "horn sounding", the "report to the public agency", and the "window open after the hold time elapses". , Or the content of control including "door lock unlocked after elapse of hold time" is determined (step S29), and the process ends.

  By the process of step S29, the control content determination unit 242 determines the content of the control as “lighting of the hazard lamp”, “report to the vehicle owner”, “sounding horn”, “report to the public agency”, “elapsed hold time”. The window is later opened "and the door lock is unlocked after the hold time has elapsed. In addition, the control content determination unit 242 determines the content of the control as at least one of “lighting of a hazard lamp” or “reporting to a vehicle owner”, “ringing a horn”, and “reporting to a public organization”. , "The window is opened after the elapse of the hold time" or at least one of "the door lock is unlocked after the elapse of the hold time".

  The “horn sound” and the “report to public authorities” are the same as the control added in step S23, and thus the description is omitted.

  "Window open after elapse of hold time" and "door lock unlock after elapse of hold time" are the same as the control added in step S28, and thus description thereof is omitted.

  In an area that does not correspond to any of the danger area, the downtown area, the parking lot of the commercial facility, and the residential area, for example, in an area such as a farmland or a mountainous area, there is a relatively high possibility that there is no person who can cope with leaving. Therefore, it is preferable that the notification to the public organization be executed promptly. In addition, when sounding a horn in such an area, there is little possibility that the horn will be considered annoying because there are few people around. On the other hand, if there is a person around, it is expected that the horn will notice and respond to leaving. Therefore, it is preferable that the horn beep immediately.

  On the other hand, even if the person escapes from the vehicle compartment in an area where there are few people around, there is a great possibility that an appropriate response such as rescue cannot be immediately received. Rather, it is considered safer to wait for a response by a public agency in the vehicle compartment, so the control content determination unit 242 controls the window opening and the door lock unlocking to be performed after the elapse of the hold time.

  When the control content determination unit 242 determines the control content as described above, the abandonment-response control device 2 determines whether the position of the vehicle 1 is in any of the danger area, the downtown area, the commercial facility parking lot, and the residential area. When the vehicle 1 is included in the non-applicable area, the control of the vehicle 1 suitable for the position of the vehicle 1 can be performed.

  By executing the processing as described above, the abandonment control device 2 determines the content of control on the vehicle 1 corresponding to the abandonment according to the position of the vehicle 1. Thereby, the leaving correspondence control device 2 can cause the vehicle 1 to execute an appropriate operation according to the position of the vehicle 1.

  The leaving correspondence control device 2 can be implemented by modifying a part of the above-described embodiment.

  For example, the abandonment control device 2 may be an information processing terminal such as a server computer or a smartphone connected to the vehicle 1 via a network, instead of the ECU mounted on the vehicle 1.

  The leaving detection unit 241 of the server computer or the information processing terminal acquires, via the communication module 9, a sensor signal output from the sensor 3 provided in the vehicle 1. In addition, the server computer or the information processing terminal acquires the position of the vehicle 1 acquired by the GPS receiver 4 via the communication module 9. When leaving is detected by the leaving detector 241, the control content determination unit 242 determines the content of control on the vehicle 1 according to the acquired position. Then, the control content determined by the control content determination unit 242 is transmitted to the vehicle control device 5 via the communication module 9, and the vehicle control device 5 executes the control.

  Further, in step S21, the control content determination unit 242 may determine “air conditioner ON”, which is control for operating the air conditioner, as the control content. In this way, the temperature in the vehicle compartment is maintained at an appropriate temperature, so that it is possible to prevent poor physical condition of the abandoned person due to inappropriate temperature in the vehicle compartment, for example, the onset of heat stroke due to high temperature.

  It should be understood that those skilled in the art can make various changes, substitutions and modifications without departing from the spirit and scope of the invention.
