Description

[Technical Field]

[0001] The present disclosure relates to a vehicle control device having a function of detecting whether a child or the like has been left behind in a vehicle. [Background technology]

[0002] For example, Patent Document 1 below discloses a configuration in which, when a door opening operation occurs while the vehicle is stopped, a determination is made as to whether a child in a child seat has been left behind, and if it is determined that abandonment has occurred, an alarm is output. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-066275 Summary of the Invention [Problem to be solved by the invention]

[0004] However, as a result of detailed studies by the inventors, it was found that the configuration of Patent Document 1 outputs an alarm every time the door is opened, which causes unnecessary alarms and is bothersome to the user.

[0005] One aspect of the present disclosure is to provide a vehicle control device having a function of detecting whether a child or the like has been left behind in a vehicle, which can reduce annoyance caused by unnecessary alarms. [Means for solving the problem]

[0006] One aspect of the present disclosure is a vehicle control device (10) for controlling a vehicle (100), comprising a person detection unit (22) and a control unit (60). The person detection unit is configured to detect a person present in a first area (222) in the vehicle cabin and a person present in a second area (227) in the vehicle cabin different from the first area while the vehicle is parked. The control unit is configured to implement vehicle control different from that when the person detection unit detects a person in the first area compared to when the person detection unit detects a person in the second area.

[0007] According to this configuration, different vehicle controls are performed depending on the position of the detected person in the vehicle interior, so that different vehicle controls can be performed, such as suppressing an alarm, when there is a high possibility that other occupants, such as the driver, have noticed that a person has been left behind. Therefore, in a vehicle control device having a function for detecting a person, such as a small child, being left behind in a vehicle, it is possible to reduce the annoyance caused by unnecessary alarms.

[0008] The control unit may include a first control unit (61) and a second control unit (62). The first control unit is configured to implement a first control of the vehicle when the human detection unit detects a human in the first area. The second control unit is configured to implement a second control of the vehicle that is different from the first control when the human detection unit detects a human in the second area. Even with this configuration, it is possible to reduce the annoyance caused by unnecessary alarms. [Brief explanation of the drawings]

[0009] [Figure 1] FIG. 1 is a block diagram showing the configuration of an abandoned vehicle prevention system. [Figure 2] FIG. 2 is a plan view showing an example of antenna placement in a vehicle interior. [Figure 3] 10 is a flowchart of an alarm process. [Figure 4] 3 is a flowchart of an air conditioner control process. [Figure 5] 10 is a flowchart of a lock control process. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. [1. Embodiment] [1-1. Overview] Accidents have occurred in which people, such as young children, are trapped inside a vehicle because their guardians forget to remove them from the vehicle or leave them inside the vehicle, resulting in injuries (such as heat stroke) due to temperature changes.Even if a person is trapped inside a vehicle in this way, it is difficult for people around the vehicle to notice.

[0011] Therefore, in this embodiment, a system is proposed in which the vehicle determines that a person such as a small child has been left inside the vehicle cabin and controls the vehicle, such as notifying the user such as the driver, thereby making it less likely that a person left inside the vehicle cabin will be injured.

[0012] In this embodiment, the person is assumed to be an infant, an elderly person, a sick person, or any other person who may require assistance to get on and off the vehicle 100. However, the person may also be a concept that includes a generally healthy person, such as an adult.

[0013] [1-2. Correspondence between the configuration of the embodiment and the configuration of the present disclosure] The near field communication unit 21 of the present embodiment corresponds to the setting acquisition unit of the present disclosure, and the key communication unit 22 of the present embodiment corresponds to the person detection unit of the present disclosure.

[0014] [1-3.Configuration] The vehicle abandonment prevention system 1 is configured around a vehicle 100 and has functions for detecting a person left inside the vehicle 100, i.e., inside the vehicle cabin, and protecting the person by issuing different levels of alarm depending on the person's location. As shown in the block diagram of FIG. 1 , the vehicle abandonment prevention system 1 includes a vehicle control device 10 and a key communication unit 22. The vehicle abandonment prevention system 1 may also include a proximity communication unit 21, an external communication unit 23, a door sensor 24, a lock sensor 25, a buzzer alarm unit 26, a door opening / closing device 27, a door lock device 28, and a meter display device 29. The vehicle abandonment prevention system 1 may also include a temperature sensor 41, an engine starter 42, and an air conditioner 43.

[0015] The near field communication unit 21 is configured to be able to communicate via near field wireless communication with a preset smartphone 51 carried by a user of the vehicle 100, such as the owner of the vehicle 100 or the driver of the vehicle 100. For example, Bluetooth (registered trademark), Wi-Fi (registered trademark), etc. can be adopted as the near field wireless communication.

[0016] The user can use the smartphone 51 to set the vehicle control details when performing various processes described below to control the vehicle. For example, the user can set the vehicle interior temperature, which is the condition for operating the air conditioner 43, the set temperature, and the warning details when a warning is issued.

[0017] The near-field communication unit 21 is configured to acquire the vehicle control details set by the user of the vehicle 100. The vehicle control device 10, which will be described later, may issue an alarm or the like in accordance with the vehicle control details. In the following description, the vehicle control device 10 uses the vehicle control details that have already been set, but may also be configured to adopt different vehicle control details depending on the user's settings.

[0018] The smartphone 51 also has the function of a well-known digital key (hereinafter also referred to as a digikey). The digital key is a function that allows a mobile communication device such as the smartphone 51 to be used as a vehicle key 53. The digital key can be linked to the detection key 52 and the vehicle key 53, and may be configured so that the vehicle control details can be set for each linked detection key 52.

[0019] The key communication unit 22 is a communication device equipped with multiple antennas 221, 226 (described later) and a tuner (not shown), and has the function of communicating with the detection key 52 and the vehicle key 53 using radio waves in the RF / LF band. Because the key communication unit 22 can detect both the detection key 52 and the vehicle key 53, when a configuration for detecting the detection key 52 is added to a configuration for detecting only the vehicle key 53, no additional hardware is required on the key communication unit 22 side, making it possible to configure the unit at low cost.

[0020] The detection key 52 is configured to be able to send and receive radio waves and can communicate with the vehicle 100, but is set so that it cannot be used to lock or unlock the vehicle 100 or to operate the power supply of the vehicle 100. In other words, the detection key 52 is a key to be carried by a person who should be protected in the abandonment prevention system 1, such as a small child, and is a key intended for detecting the person. The detection key 52 is preferably attached to the person so as to move with the person, such as a key holder, wristband, or pendant.

[0021] Furthermore, the detection key 52 is associated with each vehicle 100 and is configured to be able to determine with high accuracy whether or not a person, such as a small child, is present inside the vehicle. The key communication unit 22 can detect the position of the detection key 52 inside or outside the vehicle 100 and can take measures such as issuing an alarm depending on the person's location. The detection key 52 can be registered to the vehicle 100 and its functions can be easily changed using a digital key on the smartphone 51.

[0022] Like the detection key 52, the vehicle key 53 is configured to be able to send and receive radio waves and to communicate with the vehicle 100. However, unlike the detection key 52, the vehicle key 53 is a key that is set to be able to unlock and lock the vehicle 100 and to operate the power supply of the vehicle 100.

[0023] 2, the key communication unit 22 includes a front seat-side antenna 221 and a rear seat-side antenna 226. The front seat-side antenna 221 has a detectable range set to a first region 222 in the vehicle interior, i.e., a region that includes the front seats of the vehicle 100. The front seats include the driver's seat. The rear seat-side antenna 226 has a detectable range set to a second region 227 in the vehicle interior that is different from the first region 222, i.e., a region that includes the rear seats of the vehicle 100. In the case of a vehicle that has a third row of seats, the rear seats include the second and third row seats when counted from the front.

[0024] When the key communication unit 22 detects the detection key 52 by both the front seat antenna 221 and the rear seat antenna 226, it determines that the detection key 52 is present in an area with stronger radio wave intensity. In this way, the key communication unit 22 is configured to detect a person present in the first area 222 and a person present in the second area 227 by detecting the position of the detection key 52 while the vehicle 100 is parked.

[0025] The external communication unit 23 is configured to be able to communicate with a server 54 located on the Internet outside the vehicle 100. The door sensor 24 is a sensor that detects whether each of a plurality of doors provided in the vehicle 100 is open or closed.

[0026] The lock sensor 25 is a sensor that detects the lock state of the doors of the vehicle 100, that is, whether the doors are locked or unlocked. The buzzer alarm unit 26 is a device that issues an alarm sound around the vehicle 100.

[0027] The door opening / closing device 27 is a device that uses an actuator to open and close doors such as a sliding door and a back gate that are equipped on the vehicle 100. The door locking device 28 is a device that controls the locking and unlocking of the doors.

[0028] The meter display device 29 is a device that displays the state of the vehicle 100 together with the speed of the vehicle 100. The meter display device 29 also has a function of displaying warning messages. The temperature sensor 41 is a sensor that detects the temperature inside the vehicle cabin. The engine starting device 42 is a device that starts the engine provided in the vehicle 100. The air conditioner 43 is an air conditioning device for the inside of the vehicle cabin.

[0029] The vehicle control device 10 includes a microcomputer having a CPU 11 and a semiconductor memory such as RAM or ROM (hereinafter, referred to as memory 12). Each function of the vehicle control device 10 is realized by the CPU 11 executing a program stored in a non-transitory tangible recording medium. In this example, the memory 12 corresponds to the non-transitory tangible recording medium storing the program. Furthermore, the execution of this program results in the execution of a method corresponding to the program. Note that the non-transitory tangible recording medium refers to a recording medium excluding electromagnetic waves. Furthermore, the vehicle control device 10 may include one microcomputer or multiple microcomputers.

[0030] The vehicle control device 10 includes a control unit 60, an air conditioning control unit 63, a lock control unit 64, and a notification control unit 65 as functions executed by a microcomputer. The control unit 60 includes a first control unit 61 and a second control unit 62. The method for realizing the functions of each unit included in the vehicle control device 10 is not limited to software, and some or all of the functions may be realized using one or more pieces of hardware. For example, when the functions are realized by electronic circuits that are hardware, the electronic circuits may be realized by digital circuits, analog circuits, or a combination of these.

[0031] The various control units 60 to 65 are configured to execute functions for protecting a person left behind in the vehicle cabin. For example, when the key communication unit 22 detects a person in the first area 222, the control unit 60 is configured to execute vehicle control that is different from that executed when the key communication unit 22 detects a person in the second area 227. In particular, when the key communication unit 22 detects a person in a seat other than the front seat, the first control unit 61 issues a first warning, which will be described later. Furthermore, when the key communication unit 22 detects a person in the front seat, the second control unit 62 issues a second warning, which is weaker than the first warning. Furthermore, the control unit 60 is configured to execute vehicle control in accordance with settings for vehicle control input by the user using the smartphone 51.

[0032] The air conditioner control unit 63 is configured to operate the air conditioner 43 in the vehicle 100 when the key communication unit 22 detects a person at any position within the vehicle cabin and the temperature within the vehicle cabin reaches or exceeds a preset temperature.

[0033] The lock control unit 64 is configured to prohibit the doors of the vehicle 100 from being locked when the key communication unit 22 detects a person at any position inside the vehicle compartment. The notification control unit 65 is configured to notify a pre-set contact via the server 54 on the Internet when any of the control units 60 (in this embodiment, the first control unit 61) is activated. The any of the control units may be one or more of the control unit 60, the first control unit 61, the second control unit 62, the air conditioner control unit 63, the lock control unit 64, and the notification control unit 65.

[0034] Specific processing procedures performed by the functions of the control unit 60, the first control unit 61, the second control unit 62, the air conditioner control unit 63, the lock control unit 64, and the notification control unit 65 will be described later.

[0035] [1-4. Processing] [1-4-1. Alarm processing] Next, the warning process executed by the control unit 60 (i.e., including the first control unit 61 and the second control unit 62) will be described with reference to the flowchart in Fig. 3. The warning process is a process that starts when the power supply to the vehicle 100 is turned off, for example, when the engine is stopped.

[0036] In the warning process, first, in S110, the control unit 60 determines whether or not the door has been locked. Whether or not the door has been locked is recognized by the control unit 60 using the lock sensor 25. If the control unit 60 determines in S110 that the door has not been locked, the process returns to S110.

[0037] On the other hand, if the control unit 60 determines in S110 that the door has been locked, the process proceeds to S120, where it uses the key communication unit 22 to check against the detected key 52 inside the vehicle. If the detected key 52 is present inside the vehicle, the control unit 60 can recognize the detected key 52. ​​Next, in S130, the control unit 60 determines whether the detected key 52 is present inside the vehicle.

[0038] If the control unit 60 determines in S130 that the detection key 52 is not present inside the vehicle compartment, the process returns to S110. On the other hand, if the control unit 60 determines in S130 that the detection key 52 is present inside the vehicle compartment, the process proceeds to S140, where the control unit 60 determines whether or not the detection key 52 is present in the first area 222 (i.e., the front seat).

[0039] If the control unit 60 determines in S140 that the detection key 52 is present in the first area 222, the process proceeds to S150, where the second control unit 62 issues a second warning, which is weaker than the first warning described below. The second warning is a relatively weak warning, for example, using the meter display device 29. The second warning is issued so that the driver in the driver's seat can notice it, but is not loud enough to be noticed by those around the vehicle 100.

[0040] The second warning is issued when a person who may be left behind is in the front seat. The driver in the driver's seat is likely to notice the presence of a person in the front seat. Therefore, the second warning is issued with a lower level of warning, for example, volume, vibration, lamp lighting / flashing, communication, etc., than the first warning issued when a person is in the back seat, thereby reducing the annoyance felt by the user from the warning. After processing S150, the control unit 60 ends the warning processing in FIG. 3.

[0041] On the other hand, if the control unit 60 determines in S140 that the detection key 52 is not present in the first area 222, that is, that the detection key 52 is present in the second area 227, the process proceeds to S160. The first control unit 61 issues a first warning in S160. The first warning is issued when a person who may be left behind is in the back seat.

[0042] In the first alarm, the buzzer alarm unit 26 sounds a buzzer outside the vehicle 100, and a notification is sent to the smartphone 51 (e.g., a digital key). At this time, the notification control unit 65 uses the external communication unit 23 to send a notification command to the server 54 connected via the Internet. Upon receiving the notification command, the server 54 sends a notification to a preset notification destination (e.g., the email address of the guardian of the person who owns the detection key 52). After this processing, the control unit 60 ends the alarm processing of FIG. 3.

[0043] [1-4-2. Air conditioner control processing] The air conditioner control process executed by the air conditioner control unit 63 will be described with reference to the flowchart of Fig. 4. The air conditioner control process is a process executed in parallel with the warning process described above, and is started, for example, when the power of the vehicle 100 is turned off. The air conditioner control process is a process for implementing vehicle control to protect people in the vehicle cabin when a person is left behind despite the warning process being executed. The air conditioner control process is also a process for implementing vehicle control to protect people in the vehicle cabin when people, including the driver, are sleeping in the vehicle cabin, for example.

[0044] In the air conditioner control process, first, in S210, the air conditioner control unit 63 determines whether or not the state of the vehicle 100 has changed from a state in which any door is open to a state in which all doors are closed, using the detection result of the door sensor 24. If the air conditioner control unit 63 determines in S210 that the state of the vehicle 100 has not changed from a state in which any door is open to a state in which all doors are closed, the process returns to S210.

[0045] On the other hand, if it is determined in S210 that the state has changed from one door being open to all doors being closed, the air conditioner control unit 63 executes S120 and S130 described above. If the air conditioner control unit 63 determines in S130 that the detection key 52 is not present inside the vehicle compartment, the process returns to S210. On the other hand, if the air conditioner control unit 63 determines in S130 that the detection key 52 is present inside the vehicle compartment, the process proceeds to S220, where the air conditioner control unit 63 uses the detection results of the door sensors 24 to determine whether all the doors are closed.

[0046] If the air conditioner control unit 63 determines in S220 that all doors are not closed, i.e., that one of the doors is open, the process returns to S210. On the other hand, if the air conditioner control unit 63 determines in S220 that all doors are closed, the process proceeds to S230, where it determines whether the temperature inside the vehicle compartment is equal to or higher than a preset reference temperature. The reference temperature is set to a temperature (for example, about 28°C) at which the risk of heat stroke increases.

[0047] If the air conditioning control unit 63 determines in S230 that the vehicle interior temperature is lower than the reference temperature, the process returns to S220. On the other hand, if the air conditioning control unit 63 determines in S230 that the vehicle interior temperature is equal to or higher than the reference temperature, the process proceeds to S240, where the air conditioning control unit 63 starts the engine using the engine starting device 42 in the vehicle 100, and also starts the air conditioner 43. After this process, the air conditioning control unit 63 ends the air conditioning control process of Fig. 4. Note that the notification control unit 65 may be configured to notify a pre-set contact via the server 54 on the Internet at S240.

[0048] [1-4-3. Lock control processing] The lock control process executed by the lock control unit 64 will be described with reference to the flowchart in Fig. 5. The lock control process is executed in parallel with the above-mentioned alarm process and air conditioner control process, and is started, for example, when the power supply to the vehicle 100 is turned off. The lock control process is a process that makes it easier to rescue a person who has been left behind despite the alarm process being performed.

[0049] In the lock control process, first, the above-mentioned processes from S210 to S 130 are carried out. If the lock control unit 64 determines in S 130 that the detected key 52 is not present in the vehicle compartment, the process returns to S210.

[0050] On the other hand, if the lock control unit 64 determines in S130 that the detected key 52 is present inside the vehicle compartment, the process proceeds to S310, where the process enters a mode in which the doors cannot be locked. In the mode in which the doors cannot be locked, the lock control unit 64 prohibits the door locking device 28 from being used to lock the doors, and even if the doors are manually locked, the door locking device 28 is used to unlock the doors. Note that the notification control unit 65 may be configured to send a notification to a pre-set contact via the server 54 on the Internet in S310.

[0051] Next, in S320, the lock control unit 64 determines whether any door is open. If the lock control unit 64 determines in S320 that all doors are closed, the process returns to S320.

[0052] On the other hand, if the lock control unit 64 determines in S320 that one of the doors is open, it proceeds to S330. Here, in S330 and subsequent steps, a timer is started when a person such as a small child opens a door, and after a predetermined time (e.g., after three minutes have elapsed), it is checked whether the detection key 52 is inside the vehicle interior. If the detection key 52 is not inside the vehicle interior, it is determined that the person has left, and the door is locked.

[0053] Specifically, in S330, the lock control unit 64 transitions to a mode in which the doors can be locked. In the mode in which the doors can be locked, the lock control unit 64 permits the doors to be locked using the door lock device 28. At this time, a timer is started. Next, in S340, the lock control unit 64 determines whether the state has changed from one door being open to all doors being closed.

[0054] If the lock control unit 64 determines in S340 that the state has changed from one door being open to all doors being closed, the process proceeds to S350, where the timer is cleared, and the process returns to S290.

[0055] On the other hand, if the lock control unit 64 determines in S340 that the state has not changed from one door being open to all doors being closed, that is, that the doors are still open, the process proceeds to S360. Then, in S360, the lock control unit 64 determines whether a predetermined time, for example, three minutes, has elapsed since the timer was started.

[0056] If the lock control unit 64 determines in S360 that the predetermined time has not elapsed since the timer was started, the process returns to S340. On the other hand, if the lock control unit 64 determines in S360 that the predetermined time has elapsed since the timer was started, the process proceeds to S370, where the lock control unit 64 performs a check against the detected key 52 inside the vehicle.

[0057] Next, in S380, the lock control unit 64 determines whether or not the detected key 52 is present inside the vehicle compartment. If the lock control unit 64 determines in S380 that the detected key 52 is present inside the vehicle compartment, it ends the lock control process of FIG.

[0058] On the other hand, if the lock control unit 64 determines in S380 that the detected key 52 is not present in the vehicle interior, it is highly likely that a person has left the vehicle with the door open. Therefore, the lock control unit 64 transitions the process to S390, closes the door using the door opening / closing device 27, locks the door, and ends the lock control process in Fig. 5. Note that the notification control unit 65 may be configured to notify a pre-set contact via the server 54 on the Internet in S390.

[0059] [1-3.Effects] According to the first embodiment described above in detail, the following effects are achieved. (1a) One aspect of the present disclosure is a vehicle control device 10 that controls a vehicle 100, and includes a key communication unit 22 and a control unit 60. The key communication unit 22 is configured to detect a person present in a first area 222 in the vehicle interior and a person present in a second area 227 in the vehicle interior that is different from the first area 222 while the vehicle 100 is parked. The control unit 60 is configured to perform vehicle control when the key communication unit 22 detects a person in the first area 222, which is different from vehicle control when the key communication unit 22 detects a person in the second area 227.

[0060] The control unit 60 includes a first control unit 61 and a second control unit 62. The first control unit 61 is configured to perform a first control in the vehicle 100 when the key communication unit 22 detects a person in the first area 222. The second control unit 62 is configured to perform a second control in the vehicle 100, which is different from the first control, when the key communication unit 22 detects a person in the second area 227.

[0061] According to this configuration, different vehicle controls are performed depending on the position of the detected person in the vehicle interior, so that different vehicle controls can be performed, such as suppressing an alarm, when there is a high possibility that other occupants, such as the driver, have noticed that a person has been left behind. Therefore, in the vehicle control device 10 having a function to detect that a person, such as a small child, has been left behind in the vehicle 100, it is possible to suppress annoyance caused by unnecessary alarms.

[0062] (1b) In one aspect of the present disclosure, the key communication unit 22 is configured to detect the position of a person by detecting a detection key 52, which is configured to move with the person and is capable of transmitting radio waves, using multiple antennas 221, 226. According to this configuration, the position of a person can be detected by using the strength of the radio waves emitted by the detection key 52 and detected by the multiple antennas 221 and 226.

[0063] (1c) One aspect of the present disclosure further includes an air conditioning control unit 63 configured to activate the air conditioner 43 in the vehicle 100 when the key communication unit 22 detects a person at any position within the vehicle cabin and the temperature within the vehicle cabin reaches or exceeds a predetermined temperature. With this configuration, the air conditioner 43 is turned on when the temperature inside the vehicle cabin reaches a predetermined temperature or higher, thereby preventing people inside the vehicle cabin from falling into health-damaging situations such as heatstroke.

[0064] (1d) One aspect of the present disclosure further includes a lock control unit 64 configured to prohibit the doors of the vehicle 100 from being locked when the key communication unit 22 detects a person at any position within the vehicle interior. According to this configuration, when a person is present in the vehicle compartment, the doors are prohibited from being locked, which makes it easier for passersby or others around the vehicle to rescue the person.

[0065] (1e) One aspect of the present disclosure further includes a notification control unit 65 configured to notify pre-defined contacts via a server 54 on the Internet when any of the controls 60 is activated. With this configuration, it is possible to notify the contact person via the server 54, rather than directly via a wireless connection or the like.

[0066] (1f) One aspect of the present disclosure further includes a near-field communication unit 21 configured to acquire vehicle control details preset by a user of the vehicle 100. The control unit 60 is configured to implement the user settings as vehicle control. With this configuration, the user can change the content of vehicle control.

[0067] (1g) In one aspect of the present disclosure, the first region 222 is set to the front seats of the vehicle 100, and the second region 227 is set to the seats other than the front seats of the vehicle 100. The control unit 60 (e.g., the first control unit 61) issues a first warning when the key communication unit 22 detects a person in a seat other than the front seats. The control unit 60 (e.g., the second control unit 62) issues a second warning that is weaker than the first warning when the key communication unit 22 detects a person in the front seats.

[0068] With this configuration, when a person is in the front seat, the driver is more likely to notice the person compared to when a person is in the rear seat, so the weaker second warning is issued, thereby reducing the annoyance of the warning.

[0069] 2. Other Embodiments Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments and can be implemented in various modified forms.

[0070] (2a) In the above embodiment, a person is detected using the detection key 52, but this is not limiting. For example, the position of a person inside the vehicle may be detected using a camera that captures images of the interior of the vehicle, a radar that detects objects inside the vehicle, or the like.
