Not intended.

[1. First Embodiment]
[1-1. Constitution]
The vehicle 1 according to the first embodiment shown in FIG. 1 includes a driver monitoring unit 11, an operation state detection unit 12, a vehicle state detection unit 13, a recording unit 14, a state determination device 15, an out-of-vehicle notification device 16, and an in-vehicle notification device 19. .

  The driver monitoring unit 11 includes a camera 111 as a device for monitoring a driver who drives the vehicle 1. The camera 111 is mounted in the instrument panel in front of the driver's seat so as to capture the driver's face, and outputs the captured image data to the state determination device 15 as an image signal.

The operation state detection unit 12 includes a steering angle sensor 121 and a pedal sensor 122 as a device for detecting an operation state (operation state) of the driver with respect to the vehicle 1.
The steering angle sensor 121 detects the steering angle of the steering wheel of the vehicle 1 and outputs a steering angle signal representing the detection result to the state determination device 15.

The pedal sensor 122 detects the amount of depression of the accelerator pedal of the vehicle 1 and outputs a pedal signal representing the detection result to the state determination device 15.
The vehicle state detection unit 13 includes a shift sensor 131 and a seating sensor 132 as a device for detecting the state of the vehicle 1.

The shift sensor 131 detects the operation position (shift position) of the shift lever operated by the driver, and outputs a shift signal indicating the detection result to the state determination device 15.
The seating sensor 132 detects whether or not the driver is seated, and outputs a seating signal representing the detection result to the state determination device 15.

  The recording unit 14 is a device for recording past operation state data, statistical data, and the like of the vehicle 1, and outputs the recorded data to the state determination device 15 as a recording signal. For example, the recording unit 14 calculates from a state in which the accelerator pedal state of the vehicle 1 is not depressed to a predetermined depression amount (hereinafter referred to as “reference depression amount”), which is calculated based on past operation state data. The average time to reach the depressed state is recorded. Hereinafter, this average time is referred to as “average stepping time”.

  The state determination device 15 includes a known microcomputer mainly including a CPU, a ROM, and a RAM. The state determination device 15 includes a state signal input unit 151, a state determination unit 152, and a control instruction unit 153 as functional blocks (virtual components) realized by executing an application program.

The state signal input unit 151 inputs various signals from the driver monitoring unit 11, the operation state detection unit 12, the vehicle state detection unit 13, and the recording unit 14.
The state determination unit 152 determines the state of the driver and the vehicle 1 based on various signals input by the state signal input unit 151.

  The control instruction unit 153 outputs a signal (notification signal) for notifying the state for notifying the state determined by the state determination unit 152 to the outside notification device 16 and the inside notification device 19. The state notification here is notification that is automatically performed after determining the state of the driver, and excludes notification by the driver's own intention (that is, notification performed by the driver's own operation). Note that the notification performed by the driver's own operation includes, for example, notification by turning on a hazard lamp, notification by blowing a horn, notification by passing, and the like.

  The control instruction unit 153 causes the vehicle outside notification device 16 to always perform state notification based on the determination result of the state determination unit 152 while the state determination unit 152 determines the state of the driver and the vehicle 1. In this embodiment, since the state determination unit 152 always performs determination while the ignition switch of the vehicle 1 is on (that is, while the driver is driving the vehicle 1), the state notification based on the determination result is also performed by the driver. Is always performed while driving the vehicle 1. Therefore, for example, a state in which the vehicle outside notification device 16 is not operating is also an aspect of state notification while the driver is driving the vehicle 1. Conversely, a state in which the vehicle outside notification device 16 is not operating when the state determination unit 152 is not performing the determination (for example, when the vehicle 1 is parked) does not constitute one aspect of the state notification.

Moreover, the state determination apparatus 15 determines the states of the driver and the vehicle 1 by executing a state notification process (FIG. 4) described later, and outputs a notification signal.
The vehicle outside notification device 16 is a notification device that can notify a person outside the vehicle 1 and includes a first vehicle outside notification device 17 and a second vehicle outside notification device 18. The first vehicle outside notification device 17 includes a first operation signal input unit 171, a first operation control unit 172, and a rear wiper 173 as a hardware configuration.

The first operation signal input unit 171 is an interface for inputting a notification signal from the state determination device 15.
The first operation control unit 172 includes a known microcomputer centered on a CPU, a ROM, and a RAM. A notification signal is input to the first operation control unit 172 via the first operation signal input unit 171. The first operation control unit 172 outputs a control signal for operating the rear wiper 173 according to the input notification signal.

  The rear wiper 173 is a rod-like movable part provided at the rear part of the vehicle 1 and operates according to a control signal from the first operation control part 172. The state where the rear wiper 173 is not operated and the tip thereof is directed upward (standard state; see FIG. 5A) and the position of the base of the rear wiper 173 is fixed and is reciprocating in the horizontal direction. (See FIG. 5B.) In addition, the rear wiper 173 of the present embodiment can transition to a state where the tip is directed downward (downward state, see FIG. 5D). The rear wiper 173 is likened to the tail of an animal (in this embodiment, a cat), and is decorated by being covered with a head covering made of hair. The downward state described above corresponds to the state where the animal's tail is lowered, and the state where the rear wiper 173 is reciprocating corresponds to the state where the animal's tail is swung.

The second vehicle outside notification device 18 includes a second operation signal input unit 181, a second operation control unit 182, and an ear-type device 183 as a hardware configuration.
The second operation signal input unit 181 is an interface for inputting a notification signal from the state determination device 15.

  The second operation control unit 182 includes a known microcomputer centered on a CPU, ROM, and RAM. A notification signal is input to the second operation control unit 182 via the second operation signal input unit 181. The second operation control unit 182 outputs a control signal for operating the ear device 183 according to the input notification signal.

  As shown in FIG. 5A, the ear-type device 183 is installed on the roof of the vehicle 1, and when viewed from the rear of the vehicle 1, the ear-type device 183 can be seen in the ear of an animal (a cat in this embodiment). Two devices (a left ear device 183a and a right ear device 183b) spaced apart in the left-right direction are provided. The left ear device 183a is positioned on the left side of the vehicle 1 when viewed from the rear of the vehicle 1, and the right ear device 183b is positioned on the right side of the vehicle 1 when viewed from the rear of the vehicle 1. Further, these devices are located above the door mirror when viewed from the side of the vehicle 1.

  The left ear device 183a and the right ear device 183b protrude upward, and the surfaces thereof are covered with hair. Further, the ear-type device 183 operates by operating the built-in actuator according to the control signal from the second operation control unit 182. The type of actuator is not particularly limited.

  In the present embodiment, the ear-type device 183 is in a state where the ear-type device 183 is standing (standard state; see FIG. 5A), and in a state of being refracted downward (downward state; FIG. 5 ( E) See)). In addition, the ear-type device 183 is further directed upward as compared with the standard state (upward state; see FIG. 5C), and in a state of reciprocating in the left-right direction of the vehicle 1 (FIG. 5). (See (B)). The downward state corresponds to the state where the ear tip is lowered, the upward state corresponds to the state where the ear tip is raised, and the state where the ear-type device 183 is reciprocating corresponds to the state where the ear is moving. To do.

  The in-vehicle notification device 19 is a notification device that can notify the driver, and includes a display signal input unit 191, a display control unit 192, and a display unit 193 as a hardware configuration.

The display signal input unit 191 is an interface for inputting a notification signal from the state determination device 15.
The display control unit 192 includes a known microcomputer centered on a CPU, a ROM, and a RAM. A notification signal is input to the display control unit 192 via the display signal input unit 191. In addition, the display control unit 192 causes the display unit 193 to display an image in a display mode to be described later according to the input notification signal.

  The display unit 193 is a device for displaying an image, and as shown in FIG. 2, is installed at the center of the instrument panel of the vehicle 1 and above the center. In the present embodiment, as shown in FIGS. 2 and 3, an image of an anthropomorphic vehicle 193 a that is an anthropomorphized vehicle 1 is displayed on the display unit 193. Here, the anthropomorphic vehicle 193a has eyes, ears, and a tail. As will be described later, when the anthropomorphic vehicle 193a changes (operates) in conjunction with the notification mode of the vehicle outside notification device 16, the driver and the state of the vehicle 1 are notified to the driver.

[1-2. processing]
Next, the state notification process executed by the state determination device 15 will be described with reference to the flowchart of FIG. The state notification process is started when the ignition switch of the vehicle 1 is turned on. Further, while the ignition switch is off (that is, when the vehicle 1 is parked), the ear device 183 is folded and stored (not shown), and the ignition switch is turned on. As shown in FIG. 5 (A), the expanded state (standard state) is obtained. Further, when the ignition switch is turned on, an image of the anthropomorphic vehicle 193a is displayed on the display unit 193.

First, the state determination device 15 determines the state of the driver and the state of the vehicle 1 based on various signals input by the state signal input unit 151 (S11). Here, the state determination device 15 determines the following driver state and vehicle 1 state.
(Driver status)
・ Hurry state The rush state is a state where the driver is in a hurry. The state determination device 15 determines whether or not the driver is in a rush state based on the pedal signal from the pedal sensor 122 and the recording signal from the recording unit 14. That is, first, the state determination device 15 calculates the time until the accelerator pedal state of the vehicle 2 becomes a state where the accelerator pedal is depressed from a state where it is not depressed to a reference depression amount. Then, when the calculated time is shorter than the average depression time in the past travel of the vehicle 1 by a predetermined level (for example, half or less of the average depression time), the state determination device 15 is in a rush state. Judge that there is.
-High sleepiness state The high sleepiness state is a state in which the driver's sleepiness is high. The state determination device 15 determines whether or not the driver closes the eyes based on the image signal from the camera 111, and the state where the driver closes the eyes continues for a predetermined time (for example, 5 seconds) or more. The driver state is determined to be a high sleepiness state. Further, the state determination device 15 determines whether or not the vehicle 1 is traveling while meandering based on the steering angle signal from the steering angle sensor 121, and the driver can be used even when the vehicle 1 is traveling while meandering. Is determined to be a high sleepiness state.
(State of vehicle 1)
-Departure state The departure state is a state in which the vehicle 1 is about to depart. The state determination device 15 determines the shift position based on the shift signal from the shift sensor 131. Then, when the shift position is changed from parking to drive, the state determination device 15 determines that the state of the vehicle 1 is the departure state within a predetermined time (for example, 5 seconds) from the time of change of the shift position.
-Long running state The long running state is a state in which the vehicle 1 is running for a long time. The state determination device 15 determines whether or not the driver is sitting in the driver's seat based on the seating signal from the seating sensor 132, and if the driver has been sitting in the driver's seat for a predetermined time (for example, two hours) or more, the vehicle It is determined that the state 1 is a long running state.

  The above is the state of the driver and the vehicle 1 determined by the state determination device 15. Subsequently, the state determination device 15 determines whether or not there has been a change in the state of the driver or the state of the vehicle 1 (S12). As will be described later, the processes of S11 to S17 may be executed for a plurality of cycles. In S12, the state determination device 15 compares the latest determination result of S11 with the determination result of S11 one cycle before, and determines that there is a change when the determination results are different. In the determination of S12 in the first cycle, the state determination device 15 determines that the driver state corresponds to one of the rush state and the high sleepiness state, or the state of the vehicle 1 is the departure state and the long-running state. When it corresponds to any of the states, it is determined that there has been a change.

  If the state determination device 15 determines in S12 that neither the driver state nor the vehicle 1 state has changed (S12: NO), the state determination device 15 returns to S11 described above, and repeats the processing from S11 onward.

  On the other hand, if it is determined that the state of the driver or the state of the vehicle 1 has changed (S12: YES), the state determination device 15 outputs a notification signal to the vehicle outside notification device 16 and the vehicle interior notification device 19 (S13). Here, the state determination device 15 causes the vehicle outside notification device 16 to perform state notification as follows.

  That is, when the state of the driver and the vehicle 1 becomes a normal state, the state determination device 15 causes the vehicle outside notification device 16 to perform notification according to the standard notification mode illustrated in FIG. The normal state here is a state in which the driver is in neither a rush state nor a high sleepiness state, and the state of the vehicle 1 is neither the departure state nor the long running state. The standard notification mode is a notification mode in which the rear wiper 173 is in the standard state and the ear-type device 183 is in the standard state.

  In addition, when the state of the vehicle 1 becomes the departure state, the state determination device 15 causes the rear wiper 173 to reciprocate while the state of the vehicle 1 is the departure state, as shown in FIG. The ear device 183 is caused to reciprocate. That is, when the state of the vehicle 1 becomes a departure state, the tail and ears of the vehicle 1 operate.

  Further, when the driver is in a rush state, the state determination device 15 sets the rear wiper 173 to the standard state and the ear device 183 to the upward state as shown in FIG. 5C. That is, when the driver is in a rush state, the tip of the ear of the vehicle 1 is raised.

  Further, when the state of the vehicle 1 is in a traveling state for a long time, the state determination device 15 sets the rear wiper 173 downward and the ear device 183 to the standard state as shown in FIG. That is, when the state of the vehicle 1 is in a traveling state for a long time, the tail of the vehicle 1 is lowered.

  Further, when the driver's state becomes a high sleepiness state, the state determination device 15 sets the rear wiper 173 to the standard state and the ear-type device 183 to the downward state as shown in FIG. That is, when the driver's state becomes a high sleepiness state, the tip of the ear of the vehicle 1 is lowered.

  In addition, the state determination device 15 causes the vehicle interior notification device 19 to perform state notification by changing the anthropomorphic vehicle 193a displayed on the display unit 193 in conjunction with the notification mode of the vehicle exterior notification device 16. For example, the state determination device 15 causes the display unit 193 to display an image (not shown) of the anthropomorphic vehicle 193a with the ear tip lowered when the driver's state becomes a high sleepiness state. When it is determined that there is no change in S12 (S12: NO), the state determination device 15 notifies the vehicle outside notification device 16 and the vehicle interior notification device 19 until it is determined that there is a change in S12. The state notification is continued without changing the aspect.

  Next, the state determination device 15 determines whether or not the vehicle 1 is stopped (S14). Here, as a case where the vehicle 1 stops, the case where the vehicle 1 is waiting for a signal, etc. are mentioned, for example. When the state determination device 15 determines that the vehicle 1 is not stopped, that is, when it is determined that the vehicle 1 is traveling (S14: NO), the image of the display unit 193 is displayed on the rear part of the anthropomorphic vehicle 193a. Switching to the image to be represented (see FIG. 2) (S15), the process proceeds to S17. If an image representing the rear part of the anthropomorphic vehicle 193a is already displayed on the display unit 193 before S15 is executed, the state determination device 15 continues to display an image representing the rear part of the anthropomorphic vehicle 193a on the display unit 193. Let

  On the other hand, when the state determination device 15 determines that the vehicle 1 is stopped (S14: YES), the state determination device 15 switches the image on the display unit 193 to an image representing the front portion of the anthropomorphic vehicle 193a (see FIG. 3) (S16). ), The process proceeds to S17. That is, the image representing the front portion of the anthropomorphic vehicle 193a is displayed only when the vehicle 1 is stopped. By displaying the above image only when the vehicle is stopped, the driver is prevented from staring at the anthropomorphic vehicle 193a for a long time during driving of the vehicle 1, and the driver can easily concentrate on driving. If an image representing the front part of the anthropomorphic vehicle 193a is already displayed on the display unit 193 before S16 is executed, the state determination device 15 continues to display an image representing the front part of the anthropomorphic vehicle 193a. To display.

  In S17, the state determination device 15 determines whether or not the ignition switch is off. If the state determination device 15 determines that the ignition switch is not OFF (that is, is ON) (S17: NO), the state determination device 15 returns to S11 described above and repeats the processing from S11 onward. On the other hand, if the state determination device 15 determines that the ignition switch is off (S17: YES), the state determination device 15 outputs a control command for folding and storing the ear-type device 183 to the second outside notification device 18, and the state The notification process is terminated.

[1-3. effect]
According to the embodiment detailed above, the following effects can be obtained.
(1a) In this embodiment, the state determination unit 152 determines the state of the driver, and the control instruction unit 153 notifies the vehicle outside notification device 16 of the state determined by the state determination unit 152. Therefore, when an abnormal state of the driver (a high sleepiness state and a rush state in this embodiment) is detected, information is provided for a person outside the vehicle 1 to take an appropriate action such as avoidance or stop. be able to. In addition, by being aware that the driver is informed of his / her state, it is possible to avoid unreasonable driving (for example, driving in a high sleepiness state) and promote safe driving.

  (1b) In the present embodiment, the control instruction unit 153 causes the vehicle outside notification device 16 to always perform state notification based on the determination result of the state determination unit 152 while the driver is driving the vehicle 1. Therefore, a person outside the vehicle 1 takes appropriate measures such as avoidance as compared with a case where the state notification is not always performed during driving of the vehicle 1 (for example, when notification is performed only in an emergency such as an accident). The time that can be increased. That is, in the present embodiment, not only a high sleepiness state that is likely to lead to an emergency situation but also a long-running state that is likely to lead to a high sleepiness state is notified. Therefore, a person outside the vehicle 1 can foresee the occurrence of a high sleepiness state and hence an emergency by recognizing that the vehicle 1 is in a traveling state for a long time. The time during which appropriate measures such as avoidance provided can be taken can be lengthened.

  (1c) In the present embodiment, the state determination unit 152 determines the state of the vehicle 1 in addition to the driver state, and the control instruction unit 153 indicates the state of the vehicle 1 determined by the state determination unit 152. Let them know. Therefore, it is possible to provide more information for taking an appropriate action such as avoidance to a person outside the vehicle 1 as compared with the case where only the driver's state is notified.

  (1d) In the present embodiment, the vehicle 1 includes two movable parts (rear wiper 173 and ear-type device 183) that are visible from the outside of the vehicle 1. And the state determination part 152 determines multiple types of states about the state of a driver, and the state of the vehicle 1, and the control instruction | indication part 153 alert | reports the state determined by the state determination part 152 by operating a movable part. . Therefore, in this embodiment, various notifications can be realized by operating the movable part. Further, since the notification is performed by the operation of the movable part, it is linguistic compared to the case where the notification is performed only by the notification by the language (for example, when the message is displayed on the electric bulletin board provided outside the vehicle). It is possible to effectively notify even a disadvantageous person (for example, a foreigner).

  (1e) In this embodiment, the vehicle 1 includes a rod-like movable portion (rear wiper 173) provided at the rear portion of the vehicle 1 and the left and right sides of the vehicle 1 when viewed from the rear of the vehicle 1 provided on the roof of the vehicle 1. Two projecting movable parts (a left ear device 183a and a right ear device 183b) spaced apart in the direction. Therefore, when viewed from the rear of the vehicle 1, the vehicle 1 looks like an animal with ears and a tail. Moreover, since it alert | reports using an ear | edge and a tail, the driver | operator of the following vehicle etc. which received the alert | report can be softened.

  (1f) In the present embodiment, the vehicle 1 includes the in-vehicle notification device 19, and the control instruction unit 153 also causes the in-vehicle notification device 19 to perform state notification. Therefore, the driver's own state and the state of the vehicle 1 can be notified to the driver. Further, by driving the vehicle 1 while being aware of the content notified to the person outside the vehicle 1, it is possible to avoid unreasonable driving and promote safe driving.

  (1g) In the present embodiment, the control instruction unit 153 causes the vehicle outside notification device 16 to perform a notification by operating the rear wiper 173 and the ear-type device 183 and causes the display unit 193 to display an image, thereby causing the vehicle notification device 19 to display the image. To inform. That is, the control instruction unit 153 causes the outside notification device 16 and the inside notification device 19 to perform different types of notification. Accordingly, it is possible to perform appropriate types of notifications to each person outside the vehicle 1 and the driver of the vehicle 1.

  (1h) In the present embodiment, the control instruction unit 153 causes the in-vehicle notification device 19 to perform notification by causing the display unit 193 to display an image. Therefore, various information can be notified in a short time compared to the case where notification is performed by outputting notification contents over time, such as notification by voice.

  (1i) In the present embodiment, the control instruction unit 153 displays an image (anthropomorphic vehicle 193a) obtained by anthropomorphizing the vehicle 1 on the display unit 193, and changes the mode of the anthropomorphic vehicle 193a to change the driver and the vehicle 1 Inform the driver of the condition. Therefore, the driver can recognize his / her state and the state of the vehicle 1 as an animal aspect. Thereby, the driver can intuitively recognize his / her state and the state of the vehicle 1. Furthermore, since the driver wants to avoid seeing the worn-out anthropomorphic vehicle 193a, the driver can be encouraged to avoid unreasonable driving such as long-time driving and to perform safe driving.

  In the present embodiment, the state determination unit 152 corresponds to an example of a state determination unit, the control instruction unit 153 corresponds to an example of a notification processing unit, and the state determination device 15 corresponds to an example of a vehicle state notification device. .
