JP 2005-173636 A

  By the way, when some kind of poor physical condition occurs in the driver who is in the vehicle alone, there is a possibility that the situation cannot be notified to surrounding people. For example, when the driver feels poor physical condition and stops the vehicle on the shoulder, there may be a situation in which the driver cannot turn on the emergency flashing indicator lamp (hazard lamp). In this case, since it is impossible to notify the driver of the succeeding vehicle that the vehicle is stopped on the shoulder, the driver of the succeeding vehicle may collide without noticing the stopped vehicle. In addition, when there is a driver who needs to be transported to a medical institution in a vehicle parked on the shoulder or in the parking lot, the situation cannot be notified to the surrounding people, and there is a risk that transport to the medical institution will be delayed. . Note that a device that detects a driver's drowsiness and warns the driver like the device disclosed in Patent Document 1 cannot notify the driver of the driver's situation.

  The present invention has been made in view of such circumstances. The object is to provide an in-vehicle device capable of notifying a person around the vehicle and a passenger in the vehicle that some abnormality has occurred in the driver.

  An in-vehicle device according to the present invention is an in-vehicle device provided in a vehicle and capable of controlling a room light that is lit in a predetermined manner, and a detection unit that detects a state of a body of a driver who drives the vehicle, and the detection A determination unit that determines whether or not the state detected by the unit is a predetermined state, and a lighting control unit that lights the indoor lamp in a mode different from the predetermined mode when the determination unit determines It is characterized by providing.

  According to the present invention, the in-vehicle device detects the state of the driver's body, and turns on the room light provided in the vehicle when the detected state is not a predetermined state. Moreover, the vehicle-mounted device is turned on in a manner different from the predetermined manner when the room light is normally turned on. Therefore, when the driver in the vehicle is not in a predetermined state, that is, when some abnormality has occurred in the physical condition of the driver, the situation can be notified to, for example, people around the vehicle. Further, when there is a passenger in the vehicle, the passenger can be notified, and when the driver is not aware of his own abnormality, the driver can be notified. Furthermore, since the interior lamp generally provided in the vehicle is used, the cost does not increase.

  The in-vehicle device according to the present invention is characterized in that the lighting control unit is configured to light the room light in a mode corresponding to a state detected by the detection unit.

  According to the present invention, since the interior lamp is turned on in a mode corresponding to the state of the driver's body, the state of the driver's body can be notified based on the lighting mode. For example, the interval of blinking of the interior light is made different between the case where the driver is to be urgently transported to a medical institution and the case where the driver is not, or the color of the light at the time of lighting is made different. Thereby, the person who notices the lighting of the room lamp can take an action according to the lighting mode at an early stage, and for example, the driver can be transported to a medical institution at an early stage.

  The in-vehicle device according to the present invention further includes a collision detection unit that detects a collision with an obstacle, and the lighting control unit detects a collision when the collision detection unit detects a collision, and the determination unit determines NO, The indoor lamp is lit in a manner different from the predetermined manner.

  According to the present invention, the in-vehicle device detects a collision with an obstacle, and when the collision is detected, if the state of the driver's body is not a predetermined state, the indoor light is defined as a normal predetermined mode. Light in a different manner. Therefore, when the vehicle collides with an obstacle, if any abnormality occurs in the physical condition of the driver, the situation can be notified to, for example, people around the vehicle.

  The in-vehicle device according to the present invention is characterized in that the detection unit includes at least one of a heartbeat sensor, an electroencephalogram sensor, a blood pressure sensor, and an infrared sensor.

  According to the present invention, the in-vehicle device detects the state of the driver's body using at least one of a heart rate sensor, an electroencephalogram sensor, a blood pressure sensor, and an infrared sensor. That is, based on at least one of the driver's heartbeat, brain waves, blood pressure, and body temperature, it is determined whether or not the driver's body is in a predetermined state. Therefore, based on the actual state of the driver's body, it can be determined whether or not any abnormality has occurred in the driver's physical condition. Therefore, for example, since the driver's abnormality can be detected before the driver himself notices the abnormality, notification can be made early.

  In the present invention, it is possible to notify a person around the vehicle and a passenger in the vehicle that some abnormality has occurred in the driver. As a result, for example, when the driver feels poor physical condition and the vehicle is stopped on the road shoulder, the driver of the succeeding vehicle can notice the stopped vehicle, so that the rear-end collision can be avoided. Further, a person who has noticed the abnormality of the driver can check the situation with the driver, and can be transported to a medical institution as soon as necessary. Further, when the driver is not aware of his / her abnormality, the driver can be aware that his / her physical condition is not normal.

The body ECU 10 controls the operation of the vehicle-mounted device as described above by reading and executing the control program stored in the storage unit by the control unit.

  The impact detection sensor 11 is a sensor that detects an impact received by the vehicle C from the outside. When the impact is detected, the impact detection sensor 11 sends a signal indicating the magnitude (impact force) of the detected impact to the body ECU 10. The body ECU (collision detection unit) 10 determines whether the vehicle C has collided with an obstacle based on a signal acquired from the impact detection sensor 11. For example, when the impact force detected by the impact detection sensor 11 is greater than or equal to a predetermined value, the body ECU 10 determines that the vehicle C has collided with some obstacle. Note that a predetermined value serving as a reference for determining whether or not the vehicle C collides with an obstacle is stored in advance in the storage unit of the body ECU 10.

  The foot lamp 12, the room lamp 13, and the courtesy lamp 14 are interior lights provided in the vehicle C, and are turned on / flashing / turned off in accordance with instructions from the body ECU 10, respectively. For example, the foot lamp 12 is provided in the vicinity of the feet of a person sitting in each seat of the vehicle C, the room lamp 13 is provided at an appropriate position on the ceiling of the vehicle C, for example, and the courtesy lamp 14 is provided, for example, on the vehicle C. It is provided at an appropriate position inside each door. Note that the foot lamp 12, the room lamp 13, and the courtesy lamp 14 of the present embodiment are configured to be able to light white light, red light, yellow light, and the like.

The health check ECU 20 is a control device that controls various in-vehicle devices that detect the state of the body of the driver of the vehicle C (a person sitting in the driver's seat). The vehicle C is equipped with in-vehicle devices (detection units) such as a heart rate sensor 21, an electroencephalogram sensor 22, a blood pressure sensor 23, and an infrared sensor 24, which are connected to the health check ECU 20.
The health check ECU 20 includes a control unit such as a CPU or MPU, a storage unit such as an EEPROM or a flash memory, and the like. The storage unit stores a control program executed by the control unit, various data, data generated when the control unit executes the control program, and the like. The health check ECU 20 reads out and executes the control program stored in the storage unit by the control unit, thereby controlling the operation of the in-vehicle device as described above.

  The heart rate sensor 21 detects a driver's heartbeat waveform, heart rate, and the like in accordance with an instruction from the health check ECU 20 and sends a signal indicating the detection result to the health check ECU 20. The electroencephalogram sensor 22 detects the driver's electroencephalogram in accordance with an instruction from the health check ECU 20 and sends a signal indicating the detection result to the health check ECU 20. The blood pressure sensor 23 measures the blood pressure value of the driver at predetermined time intervals in accordance with an instruction from the health check ECU 20 and sends a signal indicating the measurement result to the health check ECU 20. The infrared sensor 24 measures the driver's body temperature at predetermined time intervals in accordance with instructions from the health check ECU 20 and sends a signal indicating the measurement result to the health check ECU 20.

The electroencephalogram sensor 22 is an instrument that is used by being mounted on the driver's head or ear, for example, and is connected in advance to the health check ECU 20 via, for example, a cable. The heart rate sensor 21 and the blood pressure sensor 23 are devices that are used in contact with a driver's finger, for example, and are provided on the handle of the vehicle C, for example. The infrared sensor 24 includes an infrared irradiation unit that irradiates the driver with infrared rays, and an infrared reception unit that receives infrared rays reflected by the driver. The infrared sensor 24 is provided at a position where the driver can irradiate infrared rays, and is provided on the steering wheel or dashboard of the vehicle C.
In addition, each sensor 21-24 is not restricted to such a structure. For example, the heart rate sensor 21 and the blood pressure sensor 23 may be used by being mounted on the driver's arm, wrist, or the like. Further, the sensor for measuring the temperature of the driver is not limited to the infrared sensor 24. In addition to these sensors 21 to 24, sensors for detecting the state of the driver's body may be provided.

  In the present embodiment, a configuration in which the sensors 21 to 24 are directly connected to the health check ECU 20 is shown as an example, but the configuration is not limited to such a configuration. For example, the sensor 21 to 24 may be connected to the in-vehicle LAN, and the health check ECU 20 may receive signals from the sensors 21 to 24 through the in-vehicle LAN. The health check ECU 20 may have a wireless communication function and receive signals from the sensors 21 to 24 by wireless communication.

  Hereinafter, the processes performed by the body ECU 10 and the health check ECU 20 in the in-vehicle system of the present embodiment will be described. First, the process performed by the body ECU 10 will be described. The body ECU 10 performs the following processing when the vehicle C is operating (running and stopping). FIG. 2 is a flowchart showing a procedure of processing performed by the body ECU 10.

  The body ECU 10 acquires a signal output from the impact detection sensor 11 (S1), and determines whether the vehicle C collides with an external obstacle based on the acquired signal (S2). When it is determined that the vehicle has collided with the obstacle (S2: YES), the body ECU 10 notifies the health check ECU 20 that the collision with the obstacle has been detected via the in-vehicle LAN (S3). When it is determined that the vehicle C does not collide with an obstacle (S2: NO), the body ECU 10 skips the process of step S3.

Next, the body ECU 10 determines whether or not a lighting request for the foot lamp 12, the room lamp 13, and the courtesy lamp 14 has been acquired from the health check ECU 20 via the in-vehicle LAN (S4). The process in which the health check ECU 20 transmits a lighting request to the body ECU 10 will be described later. For example, a lighting request for blinking red light at a short time interval (for example, every 100 milliseconds) is transmitted from the health check ECU 20 to the body ECU 10. The
When it is determined that the lighting request has not been acquired (S4: NO), the body ECU 10 returns to the process of step S1. When it is determined that the lighting request has been acquired (S4: YES), the body ECU 10 turns on the foot lamp 12, the room lamp 13, and the courtesy lamp 14 according to the acquired lighting request (S5).

Next, processing performed by the health check ECU 20 will be described. The health check ECU 20 performs the following processing when the vehicle C is operating. FIG. 3 is a flowchart showing a procedure of processing performed by the health check ECU 20.
The health check ECU 20 sequentially acquires signals (signals indicating the state of the driver's body) output from the sensors 21 to 24 (S11). Further, the health check ECU 20 determines whether or not the body ECU 10 has been notified of the collision with the obstacle via the in-vehicle LAN (S12). Specifically, the health check ECU 20 determines whether or not the collision detection notified by the body ECU 10 to the health check ECU 20 in step S3 in FIG. 2 has been acquired.

  When it is determined that the collision detection with the obstacle is not notified from the body ECU 10 (S12: NO), the health check ECU (determination unit) 20 determines the state of the driver's body based on the signal acquired in step S11. Is within the normal range (predetermined state) (S13).

  For example, the health check ECU 20 determines whether or not the heart rate (number of beats per minute) detected by the heart rate sensor 21 is within a predetermined range. to decide. The health check ECU 20 determines whether the frequency or amplitude of the electroencephalogram detected by the electroencephalogram sensor 22 is within a predetermined range, and if it is within the predetermined range, determines that it is within the normal range. The health check ECU 20 may determine whether the waveform of the electroencephalogram detected by the electroencephalogram sensor 22 has a predetermined shape, and may determine that the waveform is within a normal range if the waveform is a predetermined shape. Further, the health check ECU 20 determines whether or not the blood pressure value detected by the blood pressure sensor 23 is within a predetermined range. If the blood pressure value is within the predetermined range, the health check ECU 20 determines that the blood pressure value is within the normal range and detects by the infrared sensor 24. It is determined whether or not the body temperature is within a predetermined range, and if it is within the predetermined range, it is determined that it is within the normal range. In addition, each value (for example, the minimum and maximum values of the heart rate to be the normal range, the minimum value of the frequency of the electroencephalogram to be the normal range and the normal range) The maximum value and the like are stored in advance in the storage unit of the health check ECU 20.

  When it is determined that the state of the driver's body is within the normal range (S13: YES), that is, when all the values detected by the sensors 21 to 24 are within the normal range, the health check ECU 20 The process returns to step S11. When it is determined that the state of the driver's body is not within the normal range (S13: NO), that is, when the value detected by any of the sensors 21 to 24 is not within the normal range, the health check ECU 20 It is determined whether or not the person's body is in an urgent state (a state requiring urgent transportation to a medical institution) (S14).

  Here, for example, the health check ECU 20 determines whether or not the heart rate detected by the heart rate sensor 21 is equal to or lower than the first threshold value or equal to or higher than the second threshold value (first threshold value <second threshold value). If it is less than or equal to or less than the second threshold, it is determined that the state is urgent. Further, the health check ECU 20 determines whether or not the waveform of the electroencephalogram detected by the electroencephalogram sensor 22 matches the shape of the waveform when some abnormality has occurred. Judge. Furthermore, the health check ECU 20 determines whether or not the blood pressure value detected by the blood pressure sensor 23 is equal to or lower than the first threshold value or equal to or higher than the second threshold value (first threshold value <second threshold value). If it is 2 thresholds or more, it is determined that the state is urgent. Furthermore, the health check ECU 20 determines whether the body temperature detected by the infrared sensor 24 is equal to or lower than the first threshold value or equal to or higher than the second threshold value (first threshold value <second threshold value). If it is equal to or greater than the threshold value, it is determined that the state is urgent. In addition, each value (for example, the 1st threshold value and the 2nd threshold value in the heart rate, the waveform of an electroencephalogram that makes an emergency request state, and the blood pressure value) are used as criteria for determining whether or not the driver's body is in an emergency state. The first threshold value and the second threshold value are stored in advance in the storage unit of the health check ECU 20.

  When it is determined that the driver's body is in an emergency state (S14: YES), the health check ECU (lighting control unit) 20 sends the foot lamp 12, the room lamp 13, and the courtesy to the body ECU 10 via the in-vehicle LAN. A request to turn on the lamp 14 with the emergency lighting pattern 1 (lighting request) is transmitted (S15). The emergency lighting pattern 1 is a pattern in which red light is blinked at a short time interval (for example, every 100 milliseconds). When it is determined that the driver's body is not in an emergency state (S14: NO), the health check ECU 20 promptly turns on the foot lamp 12, the room lamp 13, and the courtesy lamp 14 to the body ECU 10 via the in-vehicle LAN. 1 is transmitted (S16). The early lighting pattern 1 is, for example, a pattern in which red light is blinked at a long time interval (for example, every 200 milliseconds).

  On the other hand, when it is determined that the collision detection with the obstacle is notified from the body ECU 10 (S12: YES), the health check ECU 20 determines the driver's body based on the signal acquired in step S11, as in step S13. It is determined whether or not the state is within a normal range (S17). When it is determined that the state of the driver's body is not within the normal range (S17: NO), the health check ECU 20 lights the foot lamp 12, the room lamp 13, and the courtesy lamp 14 to the body ECU 10 via the in-vehicle LAN in an emergency. A request for lighting in pattern 2 is transmitted (S18). The emergency lighting pattern 2 is a pattern in which red light and yellow light are alternately turned on at short time intervals, for example. When it is determined that the state of the driver's body is within the normal range (S17: YES), the health check ECU 20 promptly sends the foot lamp 12, the room lamp 13, and the courtesy lamp 14 to the body ECU 10 via the in-vehicle LAN. A request for lighting with the lighting pattern 2 is transmitted (S19). The early lighting pattern 2 is, for example, a pattern in which yellow light blinks at short time intervals.

  The lighting request transmitted from the health check ECU 20 in steps S15, S16, S18, and S19 is acquired by the body ECU 10 in step S4 in FIG. In step S5 in FIG. 2, the body ECU 10 turns on the foot lamp 12 and the room lamp in a lighting manner according to the lighting pattern (emergency lighting patterns 1 and 2, emergency lighting patterns 1 and 2) indicated by the acquired lighting request. 13 and the courtesy lamp 14 are turned on. For example, when the lighting request in the emergency lighting pattern 1 is acquired, the body ECU 10 controls the foot lamp 12, the room lamp 13, and the courtesy lamp 14, and repeats turning on and off the red light at short time intervals. When the lighting request in the lighting pattern 1 at the time of emergency is acquired, the body ECU 10 controls the foot lamp 12, the room lamp 13, and the courtesy lamp 14, and repeats turning on and off the red light at long time intervals. When the lighting request in the emergency lighting pattern 2 is acquired, the body ECU 10 controls the foot lamp 12, the room lamp 13, and the courtesy lamp 14, and repeats the lighting of red light and the lighting of yellow light at short time intervals. Furthermore, when the lighting request in the lighting pattern 2 at the time of emergency is acquired, the body ECU 10 controls the foot lamp 12, the room lamp 13, and the courtesy lamp 14, and repeats turning on and off the yellow light at short time intervals.

The health check ECU 20 performs the above-described process every time a signal indicating the driver's state is acquired from each of the sensors 21 to 24. The health check ECU 20 may be configured to temporarily accumulate the signals acquired from the sensors 21 to 24 in the storage unit and perform the above-described processing at regular time intervals (periodically).
Each time the body ECU 10 acquires a lighting request from the health check ECU 20, the body ECU 10 controls the foot lamp 12, the room lamp 13, and the courtesy lamp 14 to turn on / flash the lamps 12-14 in a manner corresponding to the lighting request.

  With the above-described configuration, when any abnormality occurs in the driver's physical condition, lighting / flashing of the light by the foot lamp 12, the room lamp 13, and the courtesy lamp 14 can be used for people around the vehicle C and passengers of the vehicle C. I can inform you. Therefore, for example, even if the driver feels poor physical condition and stops the vehicle C on the shoulder, the driver of the following vehicle stops even if the driver cannot turn on the emergency flashing indicator light at that time. The vehicle C inside can be noticed and rear-end collision can be avoided. In addition, there is a high possibility that an abnormality of the driver of the vehicle C is discovered early by a person around the vehicle C and a driver of another vehicle. Thereby, the person who notices the abnormality of the driver of the vehicle C can be transported to the medical institution at an early stage. In addition, when the driver is not aware of his / her abnormality, the driver can be aware that his / her physical condition is not normal.

  In the in-vehicle system of the present embodiment, when the vehicle C does not collide with an obstacle, the lamps 12 to 14 are lit / flashed in a different manner depending on whether or not the driver is in an urgent state. When the vehicle collides with an obstacle, the lamps 12 to 14 are lit / flashed in different modes depending on whether or not the state of the driver's body is within the normal range. Thereby, the person who notices lighting / flashing by the lamps 12 to 14 of the vehicle C can grasp the state of the driver based on the lighting mode of the vehicle C, and can take an early action according to the lighting mode. . For example, the driver can be transported to a medical institution at an early stage. Even when the vehicle C collides with an obstacle, it is determined whether or not the driver is in an urgent state, and the lighting modes of the lamps 12 to 14 are changed depending on whether or not the driver is in an urgent state. It is good also as a structure made to differ. Moreover, the lighting mode of the lamps 12 to 14 is not limited to the blinking of red light at short time intervals and the blinking of red light at long time intervals as described above, and the light color is also limited to red and yellow. Absent. The lighting mode of the lamps 12 to 13 is different from the mode in which the lamps 12 to 14 are normally lit (for example, lighting of white light) as long as it is a mode that can notify the people around the vehicle C of the occurrence of the abnormality. Such an aspect may be sufficient. Furthermore, the lamps 12 to 14 to be lit / flashed, the flashing period of light, the color of light, and the like may be arbitrarily changed.

  In the present embodiment, the foot lamp 12, the room lamp 13, and the courtesy lamp 14, which are generally provided in the vehicle C, are used to notify the driver of the vehicle C that an abnormality has occurred, thus increasing the cost. Not invited. In addition, it is not restricted to the structure which lights / flashes all the foot lamp 12, the room lamp 13, and the courtesy lamp 14 similarly. For example, the foot lamp 12, the room lamp 13, and the courtesy lamp 14 may be configured to light / blink in different manners. Also, a head lamp that is provided in front of the vehicle C and illuminates the front of the vehicle C, A configuration in which hazard lamps or the like provided at the front and rear portions are further used may be used.

  The in-vehicle system of the present embodiment has a configuration in which the body ECU 10 detects whether the vehicle C has collided with an obstacle using the impact detection sensor 11. In addition to this, it is not provided with the impact detection sensor 11, based on the signals from the sensors 21 to 24, whether or not the state of the driver's body is within the normal range, and the state in which the driver needs emergency It may be determined whether or not, and a notification process (lighting process of the lamps 12 to 14) according to the determination result may be performed.

  In the in-vehicle system of the present embodiment, each sensor 21 to 24 that detects the state of the driver's body is configured to be connected to the health check ECU 20. And health check ECU20 is a state which a driver | operator's body requires urgently whether the state of a driver | operator's body is in a normal range based on the signal (information) from each sensor 21-24. It is the structure which transmits the lighting request | requirement in the lighting mode according to the determination result to body ECU10. In addition to this, for example, the health check ECU 20 transmits signals from the sensors 21 to 24 to the body ECU 10 via the in-vehicle LAN, and the body ECU 10 is based on the signals from the sensors 21 to 24 acquired from the health check ECU 20. Then, it is determined whether or not the state of the driver's body is within the normal range, and whether or not the driver's body is in an urgent state, and each of the lamps 12 to 12 is turned on in accordance with the determination result. 14 may be configured to light / blink. Moreover, the structure by which each sensor 21-24 is directly connected to body ECU10, without providing health check ECU20, and the structure by which each sensor 21-24 is connected to body ECU10 via vehicle-mounted LAN may be sufficient.
