Description

  The present invention relates to a vehicle erroneous start prevention device.

  There are cases where the driver starts the vehicle and causes an accident without realizing that the gear switching position is opposite to the traveling direction intended by the driver.

  For example, when starting a vehicle (passenger car) that is parked backwards in the garage, if the accelerator switch is stepped on while the gear switching position is in the reverse direction, the vehicle travels to the back of the garage against the driver's will. This will cause an accident such as a collision with a garage wall. In addition, it is extremely dangerous for the vehicle to start in a direction opposite to the traveling direction intended by the driver even before an accident occurs.

Therefore, in order to prevent such dangers and accidents as described above, the driver's intended traveling direction is determined using a technique for performing face recognition based on an image captured by a camera, and the determined driver There are known vehicle safety devices and driving support devices that allow the vehicle to start when the intended traveling direction and the gear switching position of the vehicle match, and to prevent the vehicle from starting when they do not match (for example, (See Patent Document 1 and Patent Document 2).
Japanese Patent Laying-Open No. 2005-14752 JP 2005-153660 A

  However, in the devices described in Patent Document 1 and Patent Document 2, for the traveling direction intended by the driver, the driver's image captured by one imaging camera provided in the vehicle is used as the vehicle safety device. (Microcomputer) and the like analyze and determine the driver's posture, face orientation, line-of-sight direction, and the like in a comprehensive manner, so that the driver's intended traveling direction may not be accurately determined.

  In particular, it is difficult to accurately determine that the traveling direction intended by the driver is backward based on an image captured by a single imaging camera provided in front of the driver.

  Specifically, for example, when the driver intends to move the vehicle backward, the driver may invert the upper body and look directly at the back with the face facing backward, or the rear view mirror or the left and right rear view mirrors. There are also cases where the user looks at the back and looks backwards indirectly. Since these plural aspects are conceivable, it is difficult to accurately determine the driver's intention by analyzing the driver's image captured by one imaging camera.

  Therefore, the present invention determines the traveling direction intended by the driver based on the driver's image captured by the imaging device provided in the vehicle, and the determined traveling direction and the gear switching position coincide with each other. In a vehicle misstart prevention device that allows the vehicle to start when the vehicle does not match, and prevents the vehicle from starting when the vehicle does not match, it is configured so that the direction of travel intended by the driver can be accurately determined. An object of the present invention is to provide an erroneous start prevention device for a vehicle that can reliably prevent an erroneous start of the vehicle in a direction contrary to the intention.

  In order to achieve the above object, the invention according to claim 1 is a vehicle travelable direction determination that determines whether the current state of the vehicle is a forward driveable state or a reverse driveable state based on a gear switching position of the gear switching mechanism. Means, an imaging device for imaging the driver seated in the driver's seat of the vehicle, and the direction of travel intended by the driver based on the image of the driver captured by the imaging device is either forward or backward The vehicle is allowed to start when the traveling direction intended by the determined driver matches the traveling direction of the vehicle determined by the vehicle traveling direction determination means, and when the vehicle does not match In the vehicular erroneous start prevention device that includes start control means for preventing the start of the vehicle and prevents erroneous start in a direction contrary to the driver's intention, the imaging device is configured so that the driver moves the vehicle forward. A first imaging camera provided at a position facing the driver, the rear window having a high possibility of directing the line of sight when the driver starts the vehicle in the reverse direction A second imaging camera provided at a position, a third imaging camera provided at a rearview mirror position where the driver is likely to turn his / her line of sight when the driver starts the vehicle in the reverse direction, and the driver The vehicle includes fourth and fifth imaging cameras provided at left and right rearview mirror positions that are likely to turn a line of sight when starting in the reverse direction, and the start control unit is configured to receive a determination result by the vehicle travelable direction determination unit. When the vehicle is capable of moving forward, the driver intends when the driver's line of sight faces the first imaging camera in the image captured by the first imaging camera. The start of the vehicle is permitted on the assumption that the row direction and the travelable direction of the vehicle coincide with each other, and when the driver's line of sight is not facing the first imaging camera, the start of the vehicle is prevented and a warning is issued to the driver. When the determination result by the vehicle travelable direction determination means is in the reverse travelable state, the driver's line of sight is the second image pickup in any of the images picked up by the second image pickup camera to the fifth image pickup camera. When facing the camera through the fifth imaging camera, the vehicle is permitted to start on the assumption that the traveling direction intended by the driver matches the travelable direction of the vehicle, and the driver's line of sight is the second imaging camera through When it is not suitable for any of the fifth imaging cameras, the vehicle is prevented from starting and a warning is issued to the driver, thereby reliably preventing erroneous starting in a direction contrary to the driver's intention. It is a sign.

  According to a second aspect of the present invention, there is provided a vehicle travelable direction determining means for determining whether the current state of the vehicle is a forward advanceable state or a reverse advanceable state based on a gear switching position of the gear switching mechanism, and a driver seat of the vehicle An imaging device that images the driver seated on the vehicle, and the driver's intended traveling direction is determined based on the driver's image captured by the imaging device, and the determined driving The vehicle is permitted to start when the traveling direction intended by the person and the vehicle traveling direction discriminated by the vehicle traveling direction discriminating unit coincide with each other, and when the vehicle traveling direction does not coincide, the vehicle starts to stop starting. In a vehicle misstart prevention apparatus that includes a control unit and prevents erroneous start in a direction contrary to a driver's intention, the image pickup device is configured to be viewed when the driver starts the vehicle in a forward direction. A forward imaging camera provided at a position where the driver should be directed, and a plurality of backward imaging cameras provided at a plurality of positions where the driver is likely to turn his line of sight when starting the vehicle in the backward direction, When the determination result by the vehicle advanceable direction determination unit is a forward advanceable state, the start control unit has the driver's line of sight facing the forward imaging camera in the image captured by the forward imaging camera. The vehicle is allowed to start on the assumption that the traveling direction intended by the driver matches the direction in which the vehicle can travel, and the vehicle is prevented from starting when the driver's line of sight is not facing the forward imaging camera. When the determination result by the vehicle advancing direction determination means is in a reverse-travelable state, driving is performed in any of the images captured by the plurality of reverse-travel imaging cameras. When the driver's line of sight is facing the reverse imaging camera, the vehicle is permitted to start assuming that the traveling direction intended by the driver matches the direction in which the vehicle can travel. When the vehicle is not suitable for any of the imaging cameras, the vehicle is prevented from starting, and erroneous start in a direction contrary to the driver's intention is surely prevented.

  The invention according to claim 3 is the invention according to claim 2, wherein the plurality of backward-moving imaging cameras are an imaging camera provided at a rear window position of the vehicle, an imaging camera provided at a room mirror position of the vehicle, It is an imaging camera provided at a rearview mirror position of the vehicle.

  According to the first aspect of the present invention, there are four positions where the driver should turn the line of sight when starting the vehicle in the forward direction, and four places where the driver is likely to turn the line of sight when starting the vehicle in the backward direction. Each camera has an imaging camera at each position, and when it is confirmed that the driver's line of sight is facing each imaging camera in the image captured by each imaging camera, the vehicle is permitted to start, and the driver's line of sight When the vehicle is not suitable for the imaging camera, the vehicle is prevented from starting, so that erroneous starting in a direction contrary to the driver's intention can be reliably prevented. In addition, since a warning is issued when the start of the vehicle is blocked, the driver can immediately know that the intended traveling direction and the gear switching position do not match, change the gear switching position, etc. The response can be performed smoothly.

  According to the inventions of claims 2 and 3, there is a possibility that the driver should turn the line of sight when starting the vehicle in the forward direction, and the possibility that the driver may turn the line of sight when starting the vehicle in the backward direction. Each camera is equipped with an imaging camera at a plurality of high positions, and when it is confirmed that the driver's line of sight is facing each imaging camera in the image captured by each imaging camera, the vehicle is permitted to start, and the driver's line of sight Is not suitable for any of the imaging cameras, the vehicle is prevented from starting, so it is possible to reliably prevent erroneous starting in a direction contrary to the driver's intention.

  Hereinafter, an erroneous start prevention device for a vehicle according to an embodiment of the present invention will be described with reference to the drawings. The erroneous start prevention device 1 of this embodiment is mounted on a normal passenger car (vehicle) 2 as shown in FIGS. 1 and 2.

  The driver D can start and brake / stop the vehicle by operating the accelerator 4 and the brake 5 with his / her foot while sitting on the driver's seat 3, and can change the traveling direction of the vehicle by operating the handle 6. A gear switching mechanism 7 is provided on the left side of the driver's seat 3, and the driver D can switch the gear switching position by operating the gear switching mechanism 7 at an appropriate timing.

  For example, when the driver D tilts the operation lever 7a of the gear switching mechanism 7 forward, the vehicle 2 is switched to a forward advanceable state, and when the driver D is tilted rearward, the vehicle 2 is switched to a reverse travelable state. The gear switching mechanism 7 is electrically connected to a start control device 8 described later, and the start control device 8 is configured to recognize the current gear switch position. Further, a vehicle speed sensor (not shown) for detecting the movement of the vehicle 2 by detecting the rotation of the wheel is provided, and the accelerator 4, the brake 5 and the vehicle speed sensor are electrically connected to the start control device 8. The start control device 8 is configured to recognize the operation status of the accelerator 4 and the brake 5 by the driver D and the movement of the vehicle 2 unintended by the driver D.

  Next, five imaging cameras installed at five locations of the vehicle 2 in order to take an image of the driver D seated in the driver's seat 3 will be described.

  The first imaging camera 11 is installed in the vicinity of the proximal end of the handle 6 that directly faces the driver D to which the line of sight should be directed when the driver D starts the vehicle 2 in the forward direction.

  The second imaging camera 12 is installed near the upper part of a rear window (not shown) corresponding to the immediate rear of the driver's seat 3 where the driver D is likely to turn his / her line of sight when starting the vehicle 2 in the backward direction. The The second imaging camera 12 is installed in the line-of-sight direction of the driver D when the driver D is seated in the driver's seat 3 and looks back and looks back.

  The second imaging camera 12 is installed so that the imaging angle slightly faces the outside of the vehicle 2, and the driver D leans out of the vehicle from the door window (not shown) and looks back. It is comprised so that it can image.

  The 3rd imaging camera 13 is installed in the vicinity of the room mirror M (refer FIG. 2) with high possibility of turning a line of sight when the driver | operator D starts the vehicle 2 in a reverse drive direction. The third imaging camera 13 is directed in the direction of the driver's D when the driver D keeps his upper body facing forward and directs his face and line of sight toward the room mirror M and indirectly looks behind the room mirror M. Installed.

  The fourth imaging camera 14 and the fifth imaging camera 15 are installed in the vicinity of the left and right rearview mirrors M1 and M2, which are likely to turn their eyes when the driver D starts the vehicle 2 in the reverse direction. The fourth imaging camera 14 and the fifth imaging camera 15 are arranged such that the driver D keeps his upper body facing forward and directs his face and line of sight toward either the left or right rearview mirrors M1 and M2 via the rearview mirrors M1 and M2. It is installed in the line-of-sight direction of the driver D when looking backward.

  The first imaging camera 11 to the fifth imaging camera 15 are each connected to a start control device (start control means) 8 composed of a microcomputer, and images picked up by the respective image pickup cameras 11 to 15 are started control devices. 8 and analysis processing, which will be described in detail after face recognition, is performed by the start control device 8. The start control device 8 permits or blocks the start of the vehicle 2 based on the result of the analysis process and the gear switching position information obtained from the gear switching mechanism 7.

  Hereinafter, the start control procedure performed by the start control device 8 will be described with reference to the flowchart of FIG.

  First, the start control device 8 determines whether or not the gear switching position is in the forward direction (the vehicle 2 can be advanced) based on the gear switching position information from the gear switching mechanism 7 (S1), and the gear switching position is in the backward direction ( It is determined whether or not the vehicle 2 is in a reverse travelable state (S2).

  When the gear switching position is in the forward direction (YES in S1), it is determined whether or not the accelerator operation is performed by the driver D (S3), and when it is determined that the accelerator operation is not performed (in S3). NO), it is determined whether or not the vehicle 2 is moving based on whether or not there is an output from the vehicle speed sensor (S4).

  When it is determined that the vehicle 2 is moving (YES in S4), since the vehicle D is not intended by the driver D, erroneous start is suppressed and an alarm sound is emitted from the speaker 16 (S5). .

  If it is determined in S4 that the vehicle 2 is not moving, it is determined whether or not a brake operation has been performed by the driver D (S6). If it is determined that the brake operation has not been performed (NO in S6), it is determined again whether the vehicle 2 is moving based on whether there is an output from the vehicle speed sensor (S7).

  When it is determined that the vehicle 2 is moving (YES in S7), since the vehicle D is not intended by the driver D, erroneous start is suppressed and an alarm sound is emitted from the speaker 16 (S8). .

  When it is determined that the accelerator operation has been performed (YES in S3) or the brake operation has been performed (YES in S6), the start control device 8 determines that the start operation has been performed by the driver. An image is captured from the first imaging camera 11 (S9).

  The start control device 8 extracts a face portion from the captured image (S10), and evaluates the face direction in comparison with the database information stored in advance in the memory 8a of the start control device 8 (S11).

  Here, the processing in S10 and S11 will be described with reference to FIGS. 4 (a) to 4 (c). First, the start control device 8 extracts the face portion Df of the driver D from the captured image (FIG. 4A) based on the area and shape of the skin color portion in the process of S10, and this face portion Df. Whether or not the orientation of the face is within a normal range, and a plurality of sample images (FIGS. 4B and 4C) of the face portion Df stored in the memory 8a as database information The degree of deviation from the front direction is evaluated (S11).

  Specifically, the sample image stored in the memory 8 a is an image of the face portion Df in a state where the driver D looks toward the first imaging camera 11. The driver D changes the direction of the face little by little in a normal posture with the face facing forward when the vehicle 2 is started in the forward direction, and takes a plurality of images in advance by the first imaging camera 11, and the database Information is stored in the memory 8a.

  Then, the start control device 8 compares the extracted face part (FIG. 4A) Df with the face part Df of each sample image (FIGS. 4B and 4C) in the process of S11. Then, it is evaluated whether or not the face orientation is in a normal range, and if it is in a normal range, how far the face is off.

  For example, when the extracted face part (FIG. 4 (a)) Df and the face part Df of the sample image (FIG. 4 (c)) are compared, the amount of deviation calculated from the area of the skin color part or the like is the extracted face part. (FIG. 4 (a)) If the amount of deviation is smaller than the amount of deviation when comparing Df and the face portion Df of the sample image (FIG. 4 (b)), the orientation of the face is within the normal range, but slightly to the right. It is evaluated that it is suitable.

  Next, the start control device 8 extracts the position of the pupil E from the captured image, and calculates the direction of the line of sight from the relative positional relationship between the pupil E and the white-eye portion Ew (S12). At this time, the line-of-sight direction is corrected based on the evaluation result of the face orientation performed in S11.

  For example, in the case of an image as shown in FIG. 4C, the relative position relationship between the pupil E and the white-eye portion Ew results in a calculation that the line-of-sight direction is slightly to the left. The line-of-sight direction is corrected to almost the front direction according to the evaluation result (the face is facing slightly to the right).

  The start control device 8 finally determines whether or not the traveling direction intended by the driver D is the forward direction based on the calculation result of the line-of-sight direction in S8 and the evaluation result of the face direction in S11 (S9). ).

  Specifically, when the line-of-sight direction is front-facing, it is determined that the driver is looking in the direction (forward) of the first imaging camera 11, and the traveling direction intended by the driver D is the forward direction. If it is determined that there is (YES in S13) and the line-of-sight direction is not the front direction, it is determined that the traveling direction intended by the driver D is not the forward direction (NO in S13).

  Even if it is calculated that the line-of-sight direction is the front direction in S12, the evaluation result in S11 is that the face direction is greatly deviated from the front direction (for example, there is almost no skin color area). If it is a case), it is possible to determine that the traveling direction intended by the driver is not the forward direction in the determination in S13.

  Thus, since it is determined whether or not the traveling direction intended by the driver D is the forward direction based on the two types of evaluation results, it is possible to make a more accurate determination. The evaluation result of the face orientation is used supplementarily.

  If it is determined in S13 that the traveling direction intended by the driver D is the forward direction (YES in S13), the erroneous start suppression is canceled (S15), and the vehicle 2 starts in the forward direction ( S16). The erroneous start suppression is, for example, electrically invalidating the accelerator operation.

  If it is determined in S13 that the direction of travel intended by the driver D is not the forward direction (NO in S13), erroneous start suppression is continued and an alarm sound is emitted from the speaker 16 (S14). . The warning sound may be a simple mechanical sound or a voice message that specifically informs the driver D that the gear switching position is opposite to the traveling direction intended by the driver D. .

  Next, the case where the gear switching position is in the reverse direction (YES in S2) will be described.

  When the gear switching position is in the reverse direction (YES in S2), it is determined whether or not the accelerator operation is performed by the driver D (S17), and when it is determined that the accelerator operation is not performed (in S17). NO) determines whether or not the vehicle 2 is moving based on whether or not there is an output from the vehicle speed sensor (S18).

  When it is determined that the vehicle 2 is moving (YES in S18), since the movement of the vehicle 2 is not intended by the driver D, erroneous start is suppressed and an alarm sound is emitted from the speaker 16 (S19). .

  If it is determined in S18 that the vehicle 2 is not moving, it is determined whether or not a brake operation has been performed by the driver D (S20). If it is determined that the brake operation is not performed (NO in S20), it is determined again whether the vehicle 2 is moving based on whether there is an output from the vehicle speed sensor (S21).

  If it is determined that the vehicle 2 is moving (YES in S21), since the vehicle D is not intended by the driver D, erroneous start is suppressed and an alarm sound is emitted from the speaker 16 (S22). .

  When it is determined that the accelerator operation has been performed (YES in S17) or the brake operation has been performed (YES in S20), the start control device 8 determines that the start operation has been performed by the driver D. Then, an image is taken from the second imaging camera 12 (S23).

  The start control device 8 extracts the face portion Df from the captured image (S24) and compares it with the database information stored in advance in the memory 8a of the start control device 8, as in the case where the gear switching position is the forward direction. Then, the orientation of the face is evaluated (S25).

  At this time, the database information (sample image) to be compared by the start control device 8 is the second imaging camera 12 in a state in which the driver D previously flips the upper body backward and directs his line of sight toward the second imaging camera 12. Or an image captured by the second imaging camera 12 in a state of leaning over from the door window and looking back.

  Then, the start control device 8 compares the face portion Df extracted in the process of S25 with the face portion Df of each sample image to determine whether the face orientation is in a normal range or not, and to what extent is the normal range. It is evaluated whether it is out of direction (facing to the second imaging camera 12).

  Next, the start control device 8 extracts the position of the pupil E from the captured image, and calculates the direction of the line of sight from the relative positional relationship between the pupil E and the white-eye portion Ew (S26). At this time, the line-of-sight direction is corrected based on the evaluation result of the face orientation performed in S25.

  Then, the start control device 8 finally determines whether or not the traveling direction intended by the driver D is the backward traveling direction based on the calculation result of the gaze direction in S26 and the evaluation result of the face orientation in S25 (S27). ).

  When the line-of-sight direction is directed to the second imaging camera 12, it is determined that the driver D is looking in the direction (backward) of the second imaging camera 12, and the traveling direction intended by the driver D is backward. It is determined that the direction is the direction (YES in S27), and if the line-of-sight direction is not directed to the second imaging camera 12, it is determined that the traveling direction intended by the driver D is not the backward direction (NO in S27). .

  In determining whether or not the direction intended by the driver D in S27 is the reverse direction, evaluation of the face direction of the driver D other than the line-of-sight direction may be used in an auxiliary manner as in S13.

  If it is determined in S27 that the direction of travel intended by the driver D is the reverse direction (YES in S27), the erroneous start suppression is canceled (S31), and the vehicle 2 starts in the forward direction (S32). ).

  When it is determined in S27 that the traveling direction intended by the driver D is not the backward traveling direction (NO in S27), the start control device 8 determines whether or not the traveling direction intended by the driver is the backward traveling direction. It is determined whether (checking work) has been repeatedly performed from the second imaging camera 12 to the fifth imaging camera 15 (S28). If YES, the erroneous start suppression is continued and an alarm sound is output from the speaker 16. It is emitted (S30).

  If the result of determination in S28 is NO, the start control device 8 captures an image from the next imaging camera (third imaging camera) 13 (S29), and the third imaging camera 13 (of the room mirror M). The processing of S24 to S27 is repeated for the image from the imaging camera installed in the vicinity.

  As a result of comprehensively determining the image captured from the third imaging camera 13, if it is not determined that the traveling direction intended by the driver D is backward, the fourth imaging camera 14 continues. The processes of S24 to S27 are repeated for the image of.

  Similarly, the processes from S24 to S27 are repeated for the image from the fifth imaging camera 15. When it is determined that the line of sight of the driver D is facing the imaging camera in the image from any of the imaging cameras in the repetition process and the direction intended by the driver D is the reverse direction (YES in S27) At that time, the erroneous start suppression is canceled (S31), and the vehicle starts in the reverse direction (S32).

  As described above, in the erroneous start prevention device 1 of the present embodiment, when the driver D starts the vehicle 2 in the forward direction, the position where the line of sight should be directed and when the driver D starts the vehicle in the reverse direction. It is confirmed that the line of sight of the driver D is facing each imaging camera in the images captured by the imaging cameras 11, 12, 13, 14, and 15 respectively provided at four positions where the line of sight is highly likely to be directed. If the vehicle is allowed to start and the driver's D line of sight is not facing any of the imaging cameras, the vehicle will be prevented from starting. Can be prevented.

  Further, since a warning is issued when the start of the vehicle 2 is blocked, the driver D can immediately know that the intended traveling direction and the gear switching position do not match, and change the gear switching position. Etc. can be performed smoothly.

  Note that the position where the driver D is likely to turn his / her line of sight when starting the vehicle in the backward direction is not limited to the above four locations. For example, when a plurality of rearview mirrors are installed for rearward confirmation, An imaging camera may be installed at each of the room mirror positions.
