  Embodiments of the present invention will be described with reference to the drawings.

  The block diagram which comprises the vehicle equipment system 10 and the vehicle equipment 11 which concern on 1st Embodiment of this invention is shown in FIG.

  In FIG. 1, the in-vehicle device 11 includes a processing unit 12 configured by a computer unit (for example, a CPU, ROM, RAM, I / O) interface and a bus). Connected to the processing unit 12 are an AV unit 15 capable of reproducing various sound sources and video sources (for example, CD and DVD) and a navigation unit 17 capable of navigating the own vehicle. A speaker 18 is connected to the processing unit 12 via an output circuit 19. As a result, an audio signal related to processing by the AV unit 15 and the navigation unit 17 can be output as audio from the speaker 18 through the output circuit 19. Further, as will be described later, an alarm sound can be output by the speaker 18 as a warning based on a detection result obtained by detecting a predetermined external-compatible vehicle state. In addition, the processing unit 12 includes a storage unit 20 (for example, a hard disk, a flash memory, etc.) capable of storing various information such as music information and map information used in the AV unit 15 and the navigation unit 17, and an LCD or the like. A display unit 21 that displays images and the like associated with the various processes that are configured, and an operation unit 23 that can input instructions necessary for various processes that are formed on the display unit 21 in a touch panel format are connected to each other. . The operation unit 23 may include a hard key or the like as a physical key in addition to a touch panel type soft key. Furthermore, the storage unit 20 stores various programs for executing the processing unit 12 in the in-vehicle device system and the in-vehicle device 11 according to the present embodiment.

  Further, the processing unit 12 is connected to a communication unit 27 (including an antenna, a communication circuit, and the like) for performing transmission / reception by short-range wireless communication with a smartphone (mobile terminal) 28. As will be described later, predetermined warning information about the vehicle state is transmitted from the in-vehicle device 11 to the smartphone 28. Note that short-range wireless communication includes, for example, WiFi, Bluetooth (registered trademark), and the like. The in-vehicle device system 10 is configured by the in-vehicle device 11 and the smartphone 28. Further, the processing unit 12 includes a trunk open / close detection unit 25 (including an open / close detection sensor and a detection circuit) that detects an open / closed state of the trunk door of the vehicle, and a boarding that detects an occupant's start operation on the vehicle driver's seat. A detection unit 25 (including an open / close detection sensor and a detection circuit) is connected. The trunk open / close detection unit 25 detects the open / closed state of the trunk door. The trunk closed state is, for example, a state where the trunk door and the vehicle body are engaged with each other in the mechanism, and the open state. Includes a so-called half-door state in which the trunk door and the vehicle body are not mechanically engaged with each other. The boarding detection unit 25 may include either a sensor for detecting opening / closing of a door (door) of the driver's seat, a proximity sensor for detecting the proximity of an occupant to the driver's seat, or both in some cases. .

  The processing unit 12 of the in-vehicle device 11 in the in-vehicle device system 10 is processed in the procedure as shown in FIG. In FIG. 2, when the passenger opens the trunk door of a vehicle (not shown) in order to take in and out the luggage, the in-vehicle device 11 is activated (S11). For example, the above-described operation is started by reception of a detection signal by the trunk opening detection unit 25 described above. When the in-vehicle device 11 starts to operate, the processing unit 12 is connected to the occupant's smart phone 28 via the communication unit 27 via short-range wireless communication, and can communicate with each other (S12). Next, when the trunk door is closed (for example, when it is detected that the trunk door is less than a predetermined angle) after the operation of loading / unloading luggage into / from the trunk is completed, the processing unit 12 opens and closes the trunk door. A state is detected (whether the trunk door and the vehicle body are locked), and it is detected whether or not the door is in a half-door state (S13: door open / close state detecting means). Specifically, the trunk opening / closing detection unit 25 detects that the opening angle of the trunk door is equal to or smaller than a predetermined angle set in advance, and the trunk door is in an open state (a state in which the trunk door is not locked). When this is detected, the processing unit 12 detects that the trunk door is in a half-door state.

  If it is not detected that the trunk door is in a half-door state (NO in S13), it is determined that a warning or the like is unnecessary because the trunk door is closed. On the other hand, when the processing unit 12 detects that the trunk door is in a half-door state (YES in S13), the processing unit 12 further detects whether or not the driver's seat door (door) has been opened (S14: driver's seat). Opening detection means). This is because when the trunk door detects the half door state and then detects the opening of the driver's seat door, it is considered that the occupant has started boarding the driver's seat despite the trunk door being in the half door state. Therefore, even if the trunk door is in a half-door state, it is in a standby state until the opening of the driver's seat door is detected (NO in S14).

  When the processing unit 12 detects the opening of the driver's seat door (YES in S14), in order to notify the occupant's smartphone (mobile terminal) 28 of a warning, the “trunk door is in a half-door state” of the vehicle. (S15: External correspondence vehicle state information notification means) is transmitted to the smartphone 28 via the communication unit 27. On the smartphone 28 that has received the information that the “trunk door is in a half-door state” (external vehicle status information), the display of the “trunk door is in a half-door state” is displayed on the screen of the display unit. (Display control means). Note that the smartphone 28 generates ringtones (melody, buzzer, etc.) in the same manner as when an incoming call, e-mail, or the like is received. As a result, warnings can be given to passengers before boarding, and passengers outside the vehicle can quickly respond to externally compatible vehicle conditions where the trunk door is in a half-door state that needs to be resolved outside the vehicle. it can.

  As shown in FIG. 3A, on the screen of the display unit 28a of the occupant's smartphone 28, the character strings “vehicle information message” and “trunk is a half-door. (Display control means). After the warning that the trunk door is in the half door state is displayed on the display unit 28a of the smartphone 28, the processing unit 12 detects whether or not there is a response from the passenger (S16). When the processing unit 12 does not detect a response from the smartphone 28 by the occupant even after a predetermined time has passed from the notification, the processing unit 12 repeatedly determines that the “trunk door is in a half-door state” (externally-compatible vehicle state information). It transmits to the smart phone 28 via the communication part 27 (S15: External corresponding | compatible vehicle state information notification means).

  As shown in FIG. 3A, by touching an “OK” button 28 b on the screen on which the information that “the trunk door is in a half-door state” (externally compatible vehicle state information) is displayed, Response "is sent. As a result, the notification of the warning about the vehicle state corresponding to the outside such as the “half door state of the trunk door” to the passenger by the in-vehicle device 11 is completed.

  Thus, after detecting that the trunk door is in a half door state, which is a vehicle state that requires a response outside the vehicle, the trunk door is further In the conventional case, it was possible to grasp externally compatible vehicle status information, which is information about the half-door status, as a warning to the occupant's mobile terminal smartphone as a warning after sitting in the driver's seat, etc. Unlike the passenger, the passenger can know that the trunk door is in a half-door state by the above notification before getting on the vehicle, so that the trunk door can be quickly closed.

  In the present embodiment, the case where the trunk door is in a half-door state has been described as a predetermined externally-supported vehicle state that requires handling the vehicle outside the vehicle. However, the present invention is not limited to this. For example, as shown in FIG. 3B, (1) the passenger seat is in a half-door state, (2) the rear seat door (rear door) is in a half-door state, (3) the fuel filler door is in a half-door state, and (4) the rear of the vehicle When a vehicle needs to be handled by an occupant outside the vehicle, such as when the lens of an in-vehicle camera that captures the outside of the vehicle is contaminated, (5) the wiper is upright, etc. By detecting the warning, it is possible to respond promptly before boarding by notifying the warning. In the above case, it is necessary to provide each detection unit for detecting a half-door state, lens contamination, and wiper upright at each location. In this embodiment, the detection of the occupant's boarding start operation is performed by detecting the opening of the driver's seat door, but the present invention is not limited to this. A boarding start operation can be detected by detecting proximity using a proximity sensor.

  Next, an in-vehicle device according to a second embodiment of the present invention will be described. As shown in the block diagram of FIG. 4, in this embodiment, warning notification to the mobile terminal (smartphone) is not performed, but instead an alarm sound is generated or a vehicle light flashes. Common to the first embodiment. Therefore, the description will focus on the differences from the first embodiment, and the description of common parts will be omitted or simplified. Further, common parts of the configuration will be described using the same names and the same reference numerals. As described above, FIG. 4 does not include a smartphone and a communication unit, and instead, the processing unit 12 is connected to a light source unit 29 of a vehicle (not shown).

  The processing unit 12 of the in-vehicle device 11 according to the present embodiment is processed in the procedure as shown in FIG. In FIG. 5, when the trunk door of the vehicle (not shown) is opened, the in-vehicle device 11 is activated (S21). Next, when the trunk door is closed after the operation of loading / unloading luggage etc. into / from the trunk is completed, the processing unit 12 detects whether the trunk door is open or closed to detect whether it is in a half-door state ( S22: Door open / closed state detecting means). Specifically, as in the first embodiment, the trunk opening / closing detection unit 25 detects that the opening angle of the trunk door is equal to or smaller than a predetermined angle, and the trunk door is in an open state (engaged with the trunk door). The processing unit 12 detects that the trunk door is in a half-door state.

  If it is not detected that the trunk door is in a half-door state (NO in S22), the trunk door is in a closed state, and the process is terminated assuming that a warning or the like is unnecessary. On the other hand, when the processing unit 12 detects that the trunk door is in a half-door state (YES in S22), the processing unit 12 further detects whether or not the driver's seat door (door) has been opened (S23: driver's seat). Opening detection means). This is because when the trunk door detects the half door state and then detects the opening of the driver's seat door, it is considered that the occupant has started boarding the driver's seat despite the trunk door being in the half door state. Therefore, even if the trunk door is in the half-door state, it is in a standby state until the opening of the driver's seat door is detected (NO in S23).

  When the processing unit 12 detects the opening of the driver's seat door (YES in S23), the processing unit 12 transmits a warning signal to the output circuit 19 to generate a warning sound from the speaker 18 or blink the vehicle light. Is transmitted to the light source unit 29 to blink the light (S24: alarm signal control means or light blink control signal control means). In addition, you may warn by both generation | occurrence | production of an alarm sound and light blink. As a result, a warning can be issued before the occupant enters the vehicle, so that the occupant can quickly respond to the “trunk door in a half-door state” (external vehicle state) (the trunk door is closed). ) Is possible.

  After the warning, the processing unit 12 detects whether or not a response by the passenger (trunk door closing) has been made (S25). When the response by the occupant cannot be detected (NO in S25), the processing unit 12 can repeatedly generate an alarm sound or blink the light to prompt the occupant to respond. When the processing unit 12 detects a response by the occupant (YES in S25), the processing unit 12 ends the warning.

  As described above, according to this modification, a warning to a mobile terminal such as a smartphone is not notified, but a warning can be given to an occupant before boarding by an alarm sound or blinking of a light, so a solution by a quick response can be achieved. Can be planned.

  As described above, according to the present invention, when the start operation of the occupant on the vehicle is detected when the external compatible vehicle state is detected, the passenger is notified of the predetermined external compatible vehicle state. As a program for causing a computer to execute an in-vehicle device, an in-vehicle device system, a warning method in the in-vehicle device, and a process in the in-vehicle device. Useful.
