Description

  The present invention relates to a vehicle driving support device, and more particularly to a vehicle driving support device suitable for driving at a point where attention to strong wind is required.

  In general, at locations that are particularly susceptible to strong winds, such as tunnel exits and bridges, warnings that alert the driver to strong winds (e.g., caution against strong winds) Or a warning light (in other words, a warning light) is displayed. However, unless the driver independently recognizes the state of the windsock and the display state of the warning board, he / she cannot operate in preparation for strong winds, and may be exposed to danger such as lateral slip due to strong winds.

  Therefore, as a technique for avoiding such a danger, for example, as shown in Patent Document 1, when information that a strong wind is blowing at a tunnel exit based on weather information has been obtained so far. In the past, a navigation device for a vehicle that provides guidance on "Warning at the side of the tunnel exit" has been proposed.

Japanese Patent Laid-Open No. 10-247299 JP 2002-303527 A

  However, wind directions and wind speeds change from moment to moment, and when relying on weather information delivered every predetermined time, it is not always possible to provide guidance that properly reflects the local wind conditions was there.

  Therefore, the present invention has been made in view of the above points, and issues a warning that calls attention to a highly reliable strong wind that appropriately reflects the actual wind condition at a point where the host vehicle is about to travel. Therefore, an object of the present invention is to provide a vehicle driving support device that can support safe driving.

  In order to achieve the above-described object, a vehicle driving support apparatus according to the present invention is mounted on a host vehicle and is capable of shooting a predetermined shooting region around the host vehicle, and a shot image of the on-board camera. In order to alert the driver to the strong wind, a predetermined object installed at a predetermined installation position around the road and having an appearance according to the wind intensity around the installation position. Object detection means for detecting a certain strong wind warning object, and strong wind attention necessity determination means for determining whether or not attention to strong wind is required based on the appearance of the strong wind warning object detected by the object detection means; In addition, when a positive determination result is obtained by the strong wind caution necessity determining means, a strong wind caution warning output means for outputting a warning for cautioning the strong wind is provided.

  According to such a configuration, the object detection unit detects the strong wind warning object from the captured image of the in-vehicle camera, and the strong wind attention necessity determination unit determines the strong wind based on the detected strong wind warning object. If it is necessary to pay attention to the wind, if a warning is required, the strong wind warning warning output means can reliably issue a warning to warn the strong wind, so no attention is required. In this case, it is possible to prevent unnecessary warnings from being issued, so that warnings that call attention to high-reliability strong winds that appropriately reflect the actual wind conditions at the point where the vehicle is about to travel are given. be able to.

  The strong wind warning object may include a windsock.

  And according to such a structure, since the appearance of the windsock detected from the image | photographed image of a vehicle-mounted camera can determine appropriately the necessity of the caution to a strong wind by the strong wind caution necessity determination means. The strong wind caution warning output means can issue a warning that calls attention to the strong wind more appropriately reflecting the actual wind condition at the point where the host vehicle is about to travel.

  Further, the strong wind warning object may include a warning plate for displaying a warning for alerting the driver to the strong wind at the time of strong wind.

  And according to such composition, based on the appearance of the warning board detected from the photography picture of an in-vehicle camera, the judgment of necessity of attention to strong wind by the strong wind attention necessity judgment means can be performed appropriately. Therefore, it is possible to issue a warning that calls attention to the strong wind more appropriately reflecting the actual wind condition at the point where the host vehicle is about to travel by the strong wind warning output means.

  Further, the vehicle includes a determination criterion setting unit that sets a determination criterion used for determining whether or not attention to the strong wind is necessary with respect to the strong wind attention necessity determination unit. Based on the information, the determination criterion may be set such that a positive determination result is more easily obtained by the strong wind attention necessity determination unit as the host vehicle is more susceptible to wind. .

  And according to such a structure, since it can be made easy to obtain a positive determination result by a strong wind caution necessity determination means, so that the own vehicle is a vehicle which is easy to be influenced by a wind, strong wind caution The warning output means can issue a warning that calls attention to the strong wind that appropriately reflects the vehicle structure of the host vehicle.

  The vehicle information storage means for storing the vehicle information of the own vehicle is provided, and the strong wind warning output means is configured to determine whether the own vehicle is affected by wind based on the vehicle information stored in the vehicle information storage means. The warning output time may be advanced as the vehicle is more susceptible to damage.

  According to such a configuration, the warning can be output earlier by the strong wind caution warning output means as the host vehicle is more susceptible to the influence of the wind. A warning that calls attention to strong winds reflected more appropriately can be given.

  Further, when a positive determination result is obtained by the other vehicle detecting means for detecting another vehicle existing in a predetermined area around the own vehicle and the strong wind attention necessity determining means, When the other vehicle is detected by the vehicle detecting means, a traveling method guidance output means for outputting a guidance of a traveling method for avoiding a collision with the other vehicle due to a strong wind may be provided.

  According to such a configuration, when there is a possibility of a collision with another vehicle due to the influence of strong wind, the traveling method for avoiding the collision can be guided by the traveling method guidance output means. It is possible to support safer driving in consideration of the influence of other vehicles at points requiring attention to strong winds.

  Furthermore, the vehicle includes a large vehicle determination unit that determines whether the other vehicle detected by the other vehicle detection unit is a large vehicle, and the travel method guidance output unit is positive by the large vehicle determination unit. When the determination result is obtained, guidance on the traveling method may be output.

  According to such a configuration, the travel method guidance output means can perform guidance of the travel method only when the other vehicle is a large vehicle, so unnecessary travel guidance is prevented and the user is confused. It can be avoided.

  According to the present invention, it is possible to issue a warning that calls attention to a highly reliable strong wind that appropriately reflects an actual wind condition at a point where the host vehicle is about to travel, and thus, a safe and smooth driving can be performed. Can support

  Hereinafter, an embodiment of a vehicle driving support apparatus according to the present invention will be described with reference to FIGS. 1 to 6.

  As shown in FIG. 1, the vehicle driving support device 1 according to the present embodiment is broadly divided into a CPU 2, a GPS receiver 3 connected to the CPU 2, an autonomous navigation sensor 4, a front camera 5 as an in-vehicle camera, and other vehicles. The vehicle driving support device 1 includes a vehicle-mounted device integrated with a vehicle-mounted navigation device. The vehicle driving support device 1 includes a detection device 6, a ROM 7, a RAM 8, a hard disk drive (HDD) 10, a display 11, a speaker 12, and an input operation unit 14. There is no.

  Here, the CPU 2 functions as a main control unit of the vehicle driving support apparatus 1 in the present embodiment, and performs various processes and controls.

  Under the control of the CPU 2, the GPS receiver 3 receives GPS information (information regarding time and orbit) distributed from GPS satellites (not shown), and outputs the received GPS information to the CPU 2 side.

  Under the control of the CPU 2, the autonomous navigation sensor 4 detects the acceleration of the host vehicle, the vehicle speed, the host vehicle direction, and the like, and outputs the detection result to the CPU 2 side. The autonomous navigation sensor 4 may be a gyro sensor or the like.

  The front camera 5 is attached to a front portion (for example, an emblem portion) of the host vehicle so that the optical axis thereof faces the front of the host vehicle. The front camera 5 is controlled by the CPU 2 under the control of the host vehicle. A predetermined shooting area in front (an area within the viewing angle) is shot, and the shot image is output to the CPU 2 side. The front camera 5 may be a super wide angle camera including a super wide angle lens such as a fisheye lens and an image sensor such as a CCD or a CMOS.

  The other vehicle detection device 6 functions as other vehicle detection means, and detects other vehicles existing in a predetermined area around the host vehicle (for example, both left and right sides) under the control of the CPU 2. Yes. The other vehicle detection device 6 may be a device that detects other vehicles existing on both the left and right sides of the own vehicle by using a radar, or may include a plurality of other vehicles installed on both the left and right sides of the own vehicle. It may be a device that detects based on a captured image of a camera (for example, a side camera).

  The ROM 7 stores an execution program for the CPU 2, and the CPU 2 executes a function as its own main control unit by executing the execution program.

  The RAM 8 is used for temporarily storing data such as processing results by the CPU 2.

  The hard disk drive 10 stores map data.

  The input operation unit 14 includes, for example, a remote control or a touch panel of the display 11, and the user can perform a predetermined input operation on the vehicle driving support device 1 using the input operation unit 14.

  Next, the CPU 2 will be described in detail. As shown in FIG. 1, the CPU 2 has a host vehicle position calculation unit 15 as one of its functional blocks. The GPS information output from the receiver 3 and the detection result output from the autonomous navigation sensor 4 are input. And the own vehicle position calculation part 15 performs the satellite navigation which calculates (detects) an own vehicle position as an absolute coordinate based on the GPS information input from the GPS receiver 3 side. In addition, the vehicle position calculation unit 15 performs autonomous navigation that calculates (detects) the vehicle position as a relative position that is a change from the previous positioning position, based on the detection result input from the autonomous navigation sensor 4 side. To do. Furthermore, the own vehicle position calculation unit 15 uses the map data stored in the hard disk drive 10 to correct the own vehicle position calculated by satellite navigation or autonomous navigation to the corresponding position on the road in the map data. Map matching processing is performed. When the map matching process is properly performed, the host vehicle position calculation unit 15 uses the host vehicle position after the map matching process as a final calculation result.

  Further, the CPU 2 has a camera video acquisition unit 16 as one of its functional blocks. The camera video acquisition unit 16 requests the front camera 5 to shoot a shooting area, and responds to this request. The captured video imaged in this way is acquired from the front camera 5.

  Further, the CPU 2 has, as one of its functional blocks, a windsock / warning plate recognition unit 17 as an object detection unit, and this windsock / warning plate recognition unit 17 is acquired by the camera image acquisition unit 16. The captured image of the front camera 5 is obtained from the camera image acquisition unit 16. The windsock / warning plate recognition unit 17 is a predetermined object installed at a predetermined installation position around the road in order to alert the driver of the strong wind from the captured image of the front camera 5 obtained. As a strong wind warning object that is an object having an appearance according to the wind intensity around the installation position, a windsock and a warning board are detected by image recognition.

  Here, as shown in FIG. 2, the windsock 19 is installed in a place where a wind path such as an exit of a tunnel or a bridge is used to visually determine the wind direction and the strength (wind speed) of the wind. The windsock 19 has an appearance that the swimming angle θ [°] shown in FIG. 2 increases counterclockwise in FIG. 2 and approaches the maximum angle 90 [°] as the wind is stronger. It has become. Further, as shown in FIG. 3, the warning plate 18 has such an appearance that a warning for alerting the driver to the attention to the strong wind is displayed during the strong wind (FIG. 3B). The warning is not displayed except during strong winds (see FIG. 3A).

  Returning to FIG. 1, the CPU 2 has, as one of its functional blocks, a strong wind caution necessity determination unit 20 as a strong wind caution necessity determination unit. The image of the windsock 19 detected by the warning plate recognition unit 17 or the image of the warning plate 18 is obtained from the windsock / warning plate recognition unit 17. Then, the strong wind caution necessity determination unit 20 recognizes the image from the swimming angle (see FIG. 2) as the appearance of the windsock 19 extracted by image recognition from the acquired image of the windsock 19 or the image of the obtained warning plate 18. Based on the presence / absence of warning display on the warning plate 18 determined by the above (appearance of the warning plate 18), a strong wind caution necessity determination, which is a determination of the necessity of caution to the strong wind, is performed.

  Further, the CPU 2 includes a determination criterion setting unit 21 as a determination criterion setting unit as one of the functional blocks. The determination criterion setting unit 21 is configured to set a determination criterion used for determining whether or not a strong wind is necessary for the strong wind attention necessity determination unit 20, and whether or not a strong wind attention is necessary based on the set determination criterion. The determination unit 20 determines whether or not strong wind attention is required. Note that the determination criterion set by the determination criterion setting unit 21 is a warning of the swimming angle threshold (lower limit value) of the windsock 19 when the determination result of the strong wind attention necessity determination is affirmative, or a warning plate 18. Is displayed, it is a criterion such as a positive result of the determination on whether or not a strong wind is necessary. The setting of the determination criterion by the determination criterion setting unit 21 is performed in accordance with an input operation using the input operation unit 14 for the operation screen after the operation screen for setting the determination criterion is displayed on the display 11, for example. You may do it.

  Further, in the present embodiment, the determination criterion setting unit 21 determines the positive wind caution necessity determination result (that is, the determination that the vehicle is more susceptible to the influence of wind based on the vehicle information of the vehicle) (that is, Determination criteria are set so that it is easy to obtain a determination result indicating that attention to strong wind is necessary. The vehicle information of the host vehicle can include information such as the vehicle height, the total length, the vehicle width, the weight, and the vehicle type of the host vehicle. The vehicle information may be input by an input operation using the input operation unit 14 on the operation screen for setting the determination criterion. For example, the determination criterion setting unit 21 determines that the swimming angle threshold value of the windsock 19 for obtaining a positive determination result of the necessity of attention to strong wind when the host vehicle is a vehicle having a relatively high vehicle height is A determination criterion is set so as to be smaller than the threshold of the swimming angle of the windsock 19 for obtaining a determination result of the positive strong wind caution necessity determination when the vehicle is a vehicle having a relatively low vehicle height. It has become. At this time, as shown in FIG. 4, a table describing the correspondence between the vehicle information (vehicle height information h in FIG. 4) and the criterion (in FIG. 4, the swimming angle θ of the windsock 19) is stored in the ROM 7 or the like. The determination criterion setting unit 21 extracts the determination criterion corresponding to the vehicle information input from the input operation unit 14 from the table and sets it in the strong wind attention necessity determination unit 20. Also good. However, it goes without saying that vehicle information other than the vehicle height such as the vehicle weight may be taken into consideration in the determination criteria.

  In addition, as for the determination criterion corresponding to the warning plate 18, only the presence or absence of warning display on the warning plate 18 may be fixed as the only determination criterion regardless of the vehicle information.

  In addition, the determination criterion setting by the determination criterion setting unit 21 may be performed as one of the initial setting items when initial setting such as operation environment setting of the vehicle driving support device 1 is performed, for example.

  Furthermore, in the present embodiment, the CPU 2 has a strong wind caution warning output unit 22 as a strong wind caution warning output unit as one of its functional blocks. When a positive determination result is obtained by the refusal determination unit 20, a warning that calls attention to strong wind (hereinafter referred to as strong wind warning) is output.

  The strong wind warning is output by, for example, displaying a warning message on the display 11 or outputting a voice via the speaker 12 such as “Please be careful about the strong wind” or “Be careful about the strong wind”. You just have to do it.

  According to such a configuration, it is determined whether the strong wind attention is necessary based on the swimming angle of the windsock 19 detected from the captured image of the front camera 5 by the windsock / warning plate recognition unit 17 or the presence or absence of the display of the warning plate 18. If the determination result is affirmative, the strong wind attention warning output unit 22 can reliably output the strong wind warning warning, and if the determination result is negative, no unnecessary warning is issued. Therefore, it is possible to issue a warning that calls attention to a strong wind with high reliability that appropriately reflects the actual wind condition at the point where the host vehicle is about to travel. In addition, when the windsock 19 is detected, the more the vehicle is more susceptible to wind, the easier it is to obtain a positive determination result of strong wind caution determination. The warning which calls attention to the strong wind reflected in can be performed.

  The hard disk drive 10 is caused to function as vehicle information storage means so that the vehicle information of the host vehicle is stored in the hard disk drive 10, and the strong wind warning output unit 22 is based on the vehicle information stored in the hard disk drive 10. The output timing of the strong wind warning may be advanced as the vehicle is more susceptible to wind. For example, the strong wind caution warning output unit 22 indicates the output timing of the strong wind caution warning when the host vehicle is a vehicle with a relatively high vehicle height, and the strong wind caution warning when the host vehicle is a vehicle with a relatively low vehicle height. You may make it come ahead of the warning output time. At this time, as shown in FIG. 5, the vehicle information (vehicle height information h in FIG. 5) and the output timing of the strong wind warning are obtained (in FIG. 5, a positive determination result of strong wind attention necessity determination is obtained. A table in which the correspondence relationship with the elapsed time t) from the time point is described is held in a storage unit such as the ROM 7, and the strong wind warning output unit 22 uses this table to easily output the output timing of the strong wind warning. It may be determined. However, it goes without saying that vehicle information other than the vehicle height such as the vehicle weight may be taken into account in the output time. With this configuration, the stronger the wind warning warning can be outputted earlier as the vehicle is more susceptible to wind, so the vehicle structure of the vehicle is more appropriately reflected. A warning can be made.

  Further, the CPU 2 includes a large vehicle determination unit 24 as a large vehicle determination unit as one of the functional blocks. The large vehicle determination unit 24 receives the detection result of the other vehicle from the other vehicle detection device 6. To get. When the other vehicle detection device 6 detects another vehicle, the large vehicle determination unit 24 determines whether or not the detected other vehicle is a large vehicle. This determination is based on whether or not the image of the other vehicle detected by the radar or the in-vehicle camera has a predetermined size or more in the direction corresponding to the vehicle height and the direction corresponding to the total length. What is necessary is just to make it based on a criterion.

  Further, the CPU 2 has a traveling method guidance output unit 25 as traveling method guidance output means as one of its functional blocks. The traveling method guidance output unit 25 obtains an affirmative determination result by the strong wind caution necessity determination unit 20, detects another vehicle by the other vehicle detection device 6, and further detects a large size for the detected other vehicle. When a positive determination result is obtained by the vehicle determination unit 24, a traveling method guidance (hereinafter referred to as a traveling method guidance) for avoiding a collision with the other vehicle due to a strong wind is output. It has become. This travel method guide is a guide that can avoid a collision with the own vehicle due to a lateral deviation of the other vehicle in consideration of a travel position (travel lane) of the other vehicle with respect to the own vehicle. Depending on the situation, the mode of guidance is different. For example, when a large vehicle (another vehicle) is detected on the left side of the host vehicle on a Japanese road, that is, when the large vehicle is traveling in the left lane closest to the traveling lane of the host vehicle, The guidance output unit 25 confirms the safety ahead and accelerate to move forward, or confirm the safety on the right rear and change the lane to the right lane. The driving method guidance may be output by displaying a guidance message on the display 11 or outputting a voice via the speaker 12 (only when a lane is present on the right side of the driving lane). On the Japanese road, when a large vehicle is detected on the right side of the host vehicle, that is, when the large vehicle is traveling in the right lane closest to the traveling lane of the host vehicle, the traveling method guidance output unit 25 “Check the safety behind you, then decelerate and move backward” or “Check the safety behind the left and change the lane to the left lane” (however, the left side of your vehicle ’s lane) The driving method guidance may be output by displaying a guidance message on the display 11 or outputting a voice via the speaker 12. At this time, a table describing the correspondence between the travel method guidance and the position of the large vehicle (which may include lane information) is held in a storage unit such as the ROM 7, and the travel method guidance output unit 25 You may make it determine easily the mode of the driving method guidance which should be output using a table. In the travel method guidance, when urging the host vehicle to change lanes, it is assumed that the presence of the lane to be changed is premised. Such lane confirmation is performed by a known method such as detection of a white line by an in-vehicle camera. This may be done using technology.

  According to such a configuration, when there is a possibility of collision with a large vehicle due to the influence of a strong wind, the traveling method guidance output unit 25 can output the traveling method guidance, so a point requiring attention to the strong wind. It is possible to support safer driving in consideration of the influence of large vehicles.

  If the location data of the windsock 19 and warning plate 18 can be stored in the map data in a state corresponding to the map data, the CPU 2 is calculated by the vehicle position calculation unit 15. The front camera 5 and the other vehicle detection device 6 may be activated when the own vehicle position is matched with a point where the traveling distance to the installation position of the windsock 19 or the warning plate 18 is a predetermined distance. Then, the front camera 5 is stopped after the strong wind caution necessity determination unit 20 performs the strong wind caution necessity determination unit 20, and the other vehicle detection unit 6 is stopped after the large vehicle determination unit 24 performs the determination for one time. You may make it do. In this way, since the front camera 5 and the other vehicle detection device 6 can be activated only when necessary, power consumption can be reduced.

  Next, the operation of this embodiment will be described.

  For the sake of convenience, in the initial state, it is assumed that the host vehicle is traveling on a road and the algorithm of the vehicle driving support device 1 is activated.

  Then, from the initial state, first, in step 1 (ST1) of FIG. 6, the strong wind caution necessity determining unit 20 causes the blowing / warning plate recognizing unit 17 to blow the blow-off 19 and the warning plate 18 from the captured image of the front camera 5. It is determined whether or not at least one is detected. If detected, the process proceeds to step 2 (ST2), and if not detected, step 1 (ST1) is repeated.

  Next, in step 2 (ST2), the strong wind caution necessity determination unit 20 performs the strong wind caution necessity determination based on the swimming angle of the windsock 19 detected in step 1 (ST1) or the display state of the warning plate 18. When a positive determination result is obtained in this strong wind attention necessity determination, the process proceeds to step 3 (ST3), and when a negative determination result is obtained, the process is terminated. In step 1 (ST1), when both the windsock 19 and the warning plate 18 are detected at the same time, if either one of the appearances satisfies the positive determination criterion, step 3 is performed. Proceeding to (ST3) is preferable for safety.

  Next, in step 3 (ST3), a strong wind warning warning unit 22 outputs a strong wind warning warning.

  Next, in step 4 (ST4), the traveling method guidance output unit 25 determines whether another vehicle is detected by the other vehicle detection device 6, and if detected, the process proceeds to step 5 (ST5). If not detected, the process is terminated.

  Next, in step 5 (ST5), the traveling method guidance output unit 25 determines whether or not the other vehicle detected in step 4 (ST4) is a large vehicle. Proceed to (ST6), and if it is not a large vehicle, the process is terminated.

  Next, in step 6 (ST6), the travel method guidance output unit 25 determines the mode of travel method guidance to be output by considering the detection direction of the large vehicle, road lane information, and the like.

  Next, in step 7 (ST7), the traveling method guidance output unit 25 outputs the traveling method guidance of the aspect determined in step 6 (ST6), and the process is terminated.

  As described above, according to the present embodiment, the strong wind warning output unit 22 urges attention to a highly reliable strong wind that appropriately reflects the actual wind state at the point where the host vehicle is about to travel. Warning can be performed, and thus safe and smooth driving can be supported.
