  Hereinafter, preferred embodiments of an emergency stop indicator installation device according to the present invention will be described in detail with reference to the drawings.

  An emergency stop indicator installation device 1 shown in FIG. 1 is mounted on a vehicle and automatically drops an emergency stop indicator such as a smoke cylinder or a stop display plate on a road when the vehicle is about to stop. It is. As shown in FIG. 1, the emergency stop indicator installation device 1 includes an acceleration sensor 3, a vehicle speed sensor 5, a front monitoring camera 7, a GPS unit 9, a navigation device 11, a driver state monitor unit 15, A vehicle failure monitor unit 17, a display drop device 19, and a control ECU 21 are provided.

  The control ECU 21 is an electronic control unit mainly composed of a computer including a CPU, a ROM, and a RAM, for example. In the control ECU 21, these CPU, RAM, ROM, and the like operate in cooperation with each other according to a predetermined program so as to control the entire emergency stop display device 1.

  The acceleration sensor 3 is a sensor that detects acceleration in the front-rear direction of the host vehicle. The acceleration sensor 3 transmits the detected longitudinal acceleration information to the control ECU 21 as an acceleration signal. The control ECU 21 can calculate the acceleration in the traveling direction of the host vehicle based on the acceleration signal. The vehicle speed sensor 5 is a wheel speed sensor that detects the rotational speed of the wheel. The vehicle speed sensor 5 transmits the rotation speed as a vehicle speed signal to the control ECU 21. The control ECU 21 calculates the vehicle speed from the rotational speed of the wheels. The front monitoring camera 7 is an in-vehicle camera that images the front of the vehicle. The front monitoring camera 7 transmits the video information in front of the vehicle acquired by imaging to the control ECU 21 as a video signal.

  The GPS unit 9 is a device that acquires the current position of the host vehicle using radio waves from GPS satellites. The navigation device 11 includes map information, and can acquire the position of the host vehicle on the map in cooperation with the GPS unit 9. The navigation device 11 transmits the acquired position of the host vehicle to the control ECU 21 as a host vehicle position signal.

  The driver state monitoring unit 15 detects a situation in which the driver of the traveling vehicle cannot continue driving. The situation in which the driver cannot continue driving includes, for example, a situation in which the driver's condition is abnormal. For example, due to poor physical condition of the driver (for example, a disease such as acute heart failure) This includes situations where consciousness has dropped below a certain level. When such a situation in which driving cannot be continued occurs, the host vehicle needs to perform an emergency stop. The driver state monitor unit 15 includes a driver camera that images a driver's video, and determines the state of the driver based on an image captured by the driver camera. For example, it is determined that the state of the driver of the vehicle is abnormal when the time when the driver closes his eyes is a predetermined time or more, or when the number of times the eyes are closed for a predetermined time or more is a predetermined value or more. Otherwise, it is determined that the state of the vehicle driver is not abnormal. The driver state monitor unit 15 transmits driver information indicating whether or not the driver can continue driving as a driver information signal to the control ECU 21.

  The driver state monitor unit 15 may include a pulse meter that measures the driver's pulse and a sweat meter that measures the driver's sweat amount instead of the driver camera. Such a pulsometer and a sweat meter can be provided on a handle held by the driver, for example, so that information on the pulse and the amount of sweat can be obtained from the driver's hand. Then, the driver state monitor unit 15 can detect the abnormality of the driver based on the abnormality of the driver's pulse and the abnormality of sweating.

  The vehicle failure monitor unit 17 detects a failure of the host vehicle while traveling. This failure includes a failure in which a warning is displayed on the instrument panel of the vehicle, such as running out of lubricating oil. In this case, the vehicle failure monitor unit 17 is configured as a failure warning display unit that displays a warning on the instrument panel of the vehicle. When such a vehicle failure occurs, the host vehicle needs to perform an emergency stop. The vehicle failure monitor unit 17 transmits information indicating whether or not a vehicle failure has occurred to the instrument panel as a vehicle state signal and also transmits it to the control ECU 21.

  The indicator drop device 19 will be described with reference to FIG. FIG. 2 is a plan view schematically showing the host vehicle M viewed from above. As shown in FIG. 2, the indicator drop device 19 holds a plurality of emergency stop indicators 30 in a detachable manner. The emergency stop indicator 30 is an indicator installed on the road in order to notify the following vehicle that the host vehicle M is stopped forward when the host vehicle M has stopped in an emergency. For example, as the emergency stop indicator 30, a light emitting object such as a smoke cylinder or an LED lamp is used. Here, the indicator dropping device 19 includes five smoke cylinders 31a, 31b, 31c, 31d, and 31e as the emergency stop indicator 30. Further, the indicator drop device 19 holds one stop display plate 33 in a detachable manner. The stop display board 33 is a device having a reflective part of a hollow erect equilateral triangle, and is required by law to be installed behind the host vehicle that has stopped in an emergency.

  The indicator dropping device 19 holds the five smoke cylinders 31a to 31e arranged in order from the left in the traveling direction (arrow A) of the host vehicle M at equal intervals in the vehicle width direction over the entire vehicle width. ing. Further, the indicator dropping device 19 holds a stop display plate 33 at the center in the vehicle width direction. Such smoke cylinders 31a to 31e and the stop display plate 33 are held, for example, at the rear end of the host vehicle, and the indicator dropping device 19 makes the smoke cylinders 31a to 31e and the stop display plate 33 independent of each other. Can be dropped individually. And control ECU21 can transmit a drive signal to the indicator fall apparatus 19, and can make smoke cylinders 31a-31e and the stop display board 33 fall on a road at a desired timing, respectively. By performing the fall timing control while the host vehicle is traveling, the control ECU 21 can control the drop position / installation position of the smoke cylinders 31a to 31e and the stop display plate 33 in the front-rear direction on the road. The indicator dropping device 19 may have ignition means for igniting the smoke cylinders 31a to 31e immediately before dropping.

  Next, processing performed by the control ECU 21 of the indicator dropping device 19 when the host vehicle is traveling will be described with reference to the flowchart of FIG. 3 and FIG. In the following, it is assumed that the host vehicle M is traveling on a road 100 having three lanes as shown in FIG. 4, and the host vehicle is the left lane 100L, the center lane 100M, and the right lane 100R of the road 100. It is assumed that the vehicle is traveling in any lane.

  The control ECU 21 receives a driver information signal from the driver state monitor unit 15 and a vehicle state signal from the vehicle failure monitor unit 17 (S101). Next, the control ECU 21 determines whether or not an emergency situation has occurred based on the driver information signal and the vehicle state signal (S103). That is, when a situation in which the driver cannot continue driving is detected based on the driver information signal (Yes in S103), the control ECU 21 proceeds to a process S105 described later. Moreover, also when the vehicle failure which requires an emergency stop is detected based on a vehicle state signal (it is Yes at S103), control ECU21 advances a process to below-mentioned process S105. A vehicle failure that requires an emergency stop includes a fatal vehicle failure that makes it impossible to continue safe traveling of the host vehicle M, such as an engine trouble.

  Next, the control ECU 21 transmits a signal instructing an emergency stop of the vehicle to an automatic vehicle stop system (not shown). Based on this signal, the vehicle automatic stop system starts an emergency stop of the host vehicle M and starts deceleration of the host vehicle M (S105). Here, the vehicle automatic stop system performs only the operation of the vehicle speed and does not perform the steering operation. Therefore, the host vehicle M finally stops on the currently traveling lane.

  Next, the control ECU 21 detects which lane of the three lanes the lane in which the host vehicle M is currently traveling (hereinafter referred to as “the host vehicle travel lane”) (S107). Specifically, the control ECU 21 can detect the host vehicle travel lane based on the host vehicle position signals from the GPS unit 9 and the navigation device 11. Further, the control ECU 21 can detect the traveling lane of the host vehicle by performing image processing such as detecting a white line on the road 100 based on the image signal from the front monitoring camera 7. In addition, the control ECU 21 can acquire the number of times of steering by the steering wheel and the number of times of operation of the winker, and can use them as auxiliary information for detecting the own vehicle travel lane. In addition, when it is difficult to detect the host vehicle travel lane, the control ECU 21 may proceed with the subsequent processing assuming that the host vehicle travel lane is the central lane 100M.

  Until the vehicle automatic stop system completely stops the host vehicle M, the control ECU 21 performs one of the following three processes according to the host vehicle travel lane (S109).

  First, when the host vehicle travel lane detected in S107 is the left lane 100L, as shown in FIG. 4A, the five smoke cylinders 31a to 31e have the shape of “/ (slash)” on the road. It is dropped and installed on the road with a layout as depicted, and the stop display plate 33 is dropped and installed in front of the smoke cylinders 31a to 31e. Specific processing is as follows.

  That is, the control ECU 21 calculates predicted values such as a travel distance and time until the host vehicle M completely stops based on the acceleration signal from the acceleration sensor 3 and the vehicle speed signal from the vehicle speed sensor 5. And control ECU21 calculates a fall timing so that the five smoke cylinders 31a-31e may be finally arrange | positioned on the road with the layout shown to Fig.4 (a). Further, a fall timing for dropping and installing the stop display plate 33 at a position behind the stopped vehicle M by a predetermined distance is calculated (S111). In this case, the control ECU 21 recognizes the vehicle speed / deceleration of the host vehicle M on the basis of the acceleration signal and the vehicle speed signal, and performs calculation in consideration of the vehicle speed / deceleration of the host vehicle M. A preferred drop / installation position of the stop display plate 33 is, for example, about 30 m behind the stopped vehicle M based on laws and regulations. Here, the fall timing of each of the smoke cylinders 31a to 31e and the stop display plate 33 is expressed by, for example, the number of seconds elapsed from the emergency stop start (S105). Thus, the control ECU 21 functions as a drop control means.

  And control ECU21 transmits a drive signal to the indicator drop apparatus 19 corresponding to the calculated timing, and drops smoke cylinders 31a-31e and the stop display board 33 (S113). Here, as shown in FIG. 5, the smoke dropping cylinders 31a, 31b, 31c, 31d, and 31e are dropped and installed in this order from the left while the indicator dropping device 19 shifts the timing on the left lane 100L. Go. Then, the stop display plate 33 is dropped and installed in front of the smoke cylinder 31e, and the host vehicle M stops about 30 m in front (S125). By such processing, finally, the arrangement of the smoke cylinders 31a to 31e and the stop display plate 33 on the road as shown in FIG. 4A is achieved. In this case, the five smoke cylinders 31a to 31e are arranged on an oblique line with respect to the extending direction of the left lane 100R, and draw a “/” shape when viewed from above.

  The smoke cylinders 31a to 31e having such an arrangement appear to be connected to the shape of “/” when viewed from the succeeding vehicle M1 of the own vehicle M, so that the follower vehicle M1 is visually guided to the right of the own vehicle M. can do. That is, in a state where the host vehicle M is in an emergency stop on the left lane 100L, the right side of the host vehicle M having a wider passage width can be passed to the subsequent vehicle M1, and the safety of the subsequent vehicle M1 can be ensured. . As a result, it is possible to reduce the possibility of a rear-end collision by a subsequent vehicle and the possibility of occurrence of a traffic jam.

  Further, in the process S109, when the own vehicle travel lane is the central lane 100M, as shown in FIG. 4B, the five smoke cylinders 31a to 31e draw a “V” shape on the road. It is dropped and installed on the road in the layout, and the stop display board 33 is dropped and installed in front of the smoke cylinders 31a to 31e. In this case, the fall timing is calculated by the same calculation as the above-described S111 (S115), and the smoke cylinders 31a to 31e and the stop display plate 33 are dropped and installed based on the fall timing (S117). Here, on the central lane 100M, the indicator dropping device 19 causes the central smoke cylinder 31c to fall and install first while shifting the timing, and thereafter the smoke cylinders 31b, 31d, 31a and 31e are dropped and installed in this order. Let me go. After that, the stop display plate 33 is dropped and installed in front of the smoke cylinder 31e, and the host vehicle M stops approximately 30m in front (S125). By such a process, the arrangement of the smoke cylinders 31a to 31e and the stop display board 33 on the road as shown in FIG. In this case, the five smoke cylinders 31a to 31e draw a “V” shape when viewed from above in the central lane 100M.

  The smoke cylinders 31a to 31e having such an arrangement appear to be connected in a “V” shape when viewed from the succeeding vehicle M1 of the own vehicle M, so that the succeeding vehicle M1 is placed to the right or left of the own vehicle M. Can be visually induced. That is, when the host vehicle M is in an emergency stop on the left lane 100L, the right side or the left side of the host vehicle M can be passed to the subsequent vehicle M1, and the safety of the subsequent vehicle M1 can be ensured.

  Further, in the process S109, when the host vehicle traveling lane is the right lane 100R, as shown in FIG. 4C, the five smoke cylinders 31a to 31e have the shape of “\ (back slash)” on the road. It is dropped and installed on the road with a layout as depicted, and the stop display plate 33 is dropped and installed in front of the smoke cylinders 31a to 31e. In this case, the fall timing is calculated by the same calculation as in the above-described S111 (S119), and the smoke cylinders 31a to 31e and the stop display plate 33 are dropped and installed based on the fall timing (S121). Here, on the right lane 100R, the smoke dropping cylinders 31e, 31d, 31c, 31b, 31a are dropped and installed in this order from the right while the indicator dropping device 19 shifts the timing. Thereafter, the stop display plate 33 is dropped and installed in front of the smoke cylinder 31a, and the host vehicle M stops approximately 30m in front (S125). By such a process, the arrangement of the smoke cylinders 31a to 31e and the stop display plate 33 on the road as shown in FIG. 4C is finally achieved. In this case, the five smoke cylinders 31a to 31e are arranged on an oblique line with respect to the extending direction of the right lane 100R, and draw a “\” shape when viewed from above.

  The smoke cylinders 31a to 31e having such an arrangement appear to be connected to the shape of “\” when viewed from the succeeding vehicle M1 of the own vehicle M, so that the follower vehicle M1 is visually guided to the left of the own vehicle M. can do. That is, in a state where the host vehicle M is in an emergency stop on the right lane 100R, the left side of the host vehicle M having a wider passage width can be passed through the succeeding vehicle M1, and the safety of the following vehicle M1 can be ensured. .

  As described above, according to the emergency stop indicator installation device 1, when an emergency situation such as a driver's sudden illness or vehicle failure is detected, the emergency stop indicator 30 is connected to the road based on the own vehicle traveling lane. It can fall and control the arrangement | positioning on the road 100 of the some emergency stop indicator 30. FIG. Therefore, even in an emergency situation where the driver has no operation margin or is impossible for the driver to operate, a plurality of emergency stop indicators are arranged on the road in an optimal arrangement according to the position where the host vehicle M stops. Thirty placements are performed automatically. A two-dimensional pattern for guiding the following vehicle can be drawn on the road by the emergency stop indicator 30 that is dropped while shifting the timing.

  Moreover, according to this emergency stop indicator installation apparatus 1, the driver of the succeeding vehicle can use a simple method in which the smoke cylinders 31a to 31e held at equal intervals in the vehicle width direction are individually dropped at a predetermined timing. A two-dimensional pattern that is easy to understand visually can be drawn on the road.

  Further, the emergency stop indicator installation device 1 detects an abnormality (particularly, poor physical condition) of the driver of the own vehicle or a situation where a failure of the own vehicle has occurred as an emergency situation. In such a situation, in particular, in a situation where the driver is considered to have no room, the emergency stop indicator installation device 1 can appropriately control the arrangement of the emergency stop indicator 30 and the stop indicator plate 33 on the road. it can.

  The emergency stop indicator 30 and the stop display plate 33 may be provided with a string that is connected to the host vehicle M even after falling. By dropping the emergency stop indicator 30 while being connected to the host vehicle M with a string, the emergency stop indicator 30 can be quickly recovered during post-processing. Moreover, the emergency stop indicator 30 can be quickly recovered even when the emergency stop indicator installation device 1 malfunctions.

  Moreover, as shown to Fig.6 (a), it is good also as a structure which wraps each emergency stop indicator 30 with the gel-like substance 41 which has adhesiveness. According to this configuration, when the emergency stop indicator 30 falls on the road surface of the road 100, it adheres and is fixed on the road surface due to the adhesiveness of the gel substance 41 as shown in FIG. Therefore, the emergency stop indicators 30 after falling are prevented from rolling on the road due to inertia, and each emergency stop indicator 30 is easily installed at a desired position on the road. In this case, the gel material 41 may be further wrapped with an exterior film 43 that is broken by a drop impact. Moreover, it is preferable to use the water-soluble substance for the gel substance 41 and the exterior film 43 because the environmental load is reduced and post-treatment after use becomes easy.

  Moreover, as shown in FIG. 7, the indicator dropping device 19 may include an injection unit that horizontally injects the emergency stop indicator 30 backward and drops it on the road. For example, if the indicator drop device 19 injects the emergency stop indicator 30 horizontally rearward at the same speed V as the vehicle speed V, the relative speed of the emergency stop indicator 30 with the road surface becomes zero immediately after the injection. . Then, the emergency stop indicator 30 falls almost vertically downward due to free fall. Therefore, the emergency stop indicators 30 after falling are prevented from rolling on the road due to inertia, and each emergency stop indicator 30 is easily installed at a desired position on the road. Moreover, the control of the installation position of each emergency stop indicator 30 can be simplified without considering the rolling of each emergency stop indicator 30 due to inertia.

  In order to operate the injection means of the indicator dropping device 19, the control ECU 21 determines the same injection speed V as the vehicle speed V based on the vehicle speed signal from the vehicle speed sensor 5, and includes the injection speed V. It is assumed that the drive signal transmitted to the display dropping device 19 is transmitted. The indicator drop device 19 horizontally injects the emergency stop indicator 30 backward at the injection speed V determined in accordance with the drive signal of the control ECU 21.

  In addition, this invention is not limited to the above-mentioned embodiment. For example, in the embodiment, five emergency stop indicators 30 are used, but more complicated patterns can be drawn on the road by holding a larger number of emergency stop indicators 30 over the entire vehicle width. Is also possible.
