BEST MODE FOR CARRYING OUT THE INVENTION
(1st Embodiment)
FIG. 1 shows a first embodiment of a vehicular impatience / inattention gaze detection system according to the present invention.
[0026]
The vehicular urgency / gazing detection system includes an infrared sensor 10, an audio device 11, an incense generator 12, an ion generator 13, a display 15, a vibrator 16, and a controller 17.
[0027]
The infrared sensor 10 is arranged toward the driver's seat side, and is configured such that 38 cells are arranged in a matrix of 4 rows and 8 columns. Each cell outputs an electric signal corresponding to the amount of incident infrared light. As a result, the surface temperatures of the 32 detection areas on the driver's seat side are independently and non-contactly detected.
[0028]
The audio device 11 reads music data from a compact disk for music, converts the read music data into an analog signal, and outputs music from a speaker according to the analog signal. The scent generating device 12 is stored in the instrument panel, and is controlled by the controller 17 to release at least one fragrance of a plurality of fragrances stored in advance into the vehicle interior. . As a result, a desired scent is generated based on the control from the controller 17.
[0029]
The ion generator 13 is housed in an instrument panel and is controlled by the controller 17 to emit negative ions into the vehicle interior. The display 15 is housed in the instrument panel, and displays a desired image under the control of the controller 17. The vibrator 16 is embedded in the driver's seat, and is controlled by the controller 17 to apply vibration to the driver.
[0030]
The controller 17 includes a microcomputer, a ROM, a RAM, and the like, and performs a process for detecting a driver's impatience and calming the impulse according to a detection output from the infrared sensor 10. Further, the controller 17 performs a process for detecting a gazeless state based on an output from the infrared sensor 10 and issuing a warning to the driver.
[0031]
Next, the operation of the present embodiment will be described with reference to FIGS.
[0032]
The controller 17 executes the impatience / inattention gaze detection process according to the flowcharts shown in FIGS. This impatience / inattention detection processing is executed when the vehicle is stopped at the intersection to make a right turn. For example, an operation for instructing the operation switch of the direction indicator 19 to turn right is performed. Execution is started when the foot brake 18 is depressed.
[0033]
First, the built-in counter is reset (step 100), and based on the detection output of the infrared sensor 10, it is determined whether the driver's face has moved in the left-right direction (step 110).
[0034]
For example, after the temperature of the detection area of the infrared sensor 10 that is equal to or higher than the temperature t1 (which indicates the driver's face) decreases to the temperature t1 or lower, the left area (or the right area) of the area is determined. When the detected temperature rises to the temperature t1 or more, and the detected temperature in the left area maintains the temperature t1 or more for the time tr or more, it is determined that the driver's face has moved to the left (or right). You.
[0035]
For example, as shown in FIG. 5 (the cells M52 and M22 are omitted in the figure), the detected temperatures of the cells M42 and M52 shown in FIG. When the temperature rises to the temperature t1 or more and the detected temperature of the cells M12 and M22 is maintained at the temperature t1 or more for the time tr or more, the driver's face moves from the detection area of the cells M42 and M52 to the detection area of the cells M12 and M22. Is determined to have moved. That is, it is determined that the driver's face has moved by the width L3 of three cells (= 3 × L1: L1 is the width of one cell).
[0036]
In FIG. 4, 32 cells are individually represented by Mij, i represents a row number (1 ≦ i ≦ 8), and j represents a column number (1 ≦ j ≦ 4). FIG. 5 shows the detected temperature of the cell on the vertical axis and the time on the horizontal axis.
[0037]
As described above, when it is determined that the driver's face has moved, the face movement width L (= L3) is smaller than the reference width K0 (for example, the width of two cells: 2 × L1). Is determined to be NO in step 120 (L ≧ K0), and the moving width L is equal to or larger than a predetermined width C0 (for example, the width of three cells: 3 × L1), and YES is determined in step 130. (L ≧ C0). Thus, it is estimated that the driver is impatient.
[0038]
Accordingly, the environment of the driver in the vehicle compartment is controlled (step 131). For example, a predetermined music is output as audio from the audio device 11, a predetermined scent is generated from the scent generator 12, and a negative ion is generated from the ion generator 13. As a result, the state in which the driver is impatient can be calmed down. Thereafter, the process proceeds to step 132, where a warning generation process is executed. For example, an image is displayed on the display 15 to warn the driver of driving impatiently, or a sound output indicating the warning is output from the audio device 11.
[0039]
Further, in step 120, it is determined that the movement width L of the face is larger than the reference width K0, and the result is determined to be YES (L ≧ K0), but it is determined in step 130 that the movement width L is less than the predetermined width C0, and the result is NO. If (L <C0), the process proceeds to step 140, and the counter value of the built-in counter is incremented as the number of movements N (N = N + 1).
[0040]
Next, it is determined whether or not the number of movements N is equal to or more than a predetermined number of times C1 (step 150). If the number of times of movement N is equal to or more than the predetermined number of times C1, it is determined to be YES (N> C1). In this case, since it is estimated that the driver is impatient, the environment control processing (step 131) and the warning generation processing (step 132) are executed to calm the driver's impatience.
[0041]
Further, in step 150, when it is determined that the number of movements N is less than the predetermined number of times C1 and NO (N ≦ C1), the movement time ta (N) required for the movement of the driver's face is obtained. For example, when the driver's face moves from the detection areas of the cells M42 and M52 to the detection areas of the cells M22 and M32, as shown in FIG. 6 (the cells M52 and M32 are omitted in the figure), the detection of the cell M42 is performed. After the temperature falls to or below the temperature t1, the time required for the detected temperature of the cell M22 (or M22) to reach or exceed the temperature t1 is determined as a movement time ta (N). The vertical axis in FIG. 6 indicates the detected temperature of the cell, and the horizontal axis indicates time.
[0042]
As described above, when the moving time ta (N) is obtained, the moving speed V (N) ｛= (L) / (ta (N))｝ is obtained based on the moving time ta (N) and the moving width L. At the same time, when the obtained moving speed V (N) is equal to or higher than the predetermined speed C2, it is determined to be YES in step 180. In this case, since it is estimated that the driver is impatient, the environment control process (step 131) is executed, and the warning generation process (step 132) is executed.
[0043]
In step 180, if the determination is NO because the moving speed V (N) is lower than the predetermined speed C2, a gaze time tb (N) during which the driver's face gazes is determined. The gaze time tb (N) indicates a time during which the driver's face stops after moving.
[0044]
For example, when the face of the driver moves from the detection area of the cells M42 and M52 to the detection area of the cells M22 and M32, as shown in FIG. 6, the detected temperature of the cell M22 (or M22) becomes higher than the temperature t1. After the rise, the time required for the detected temperature of the cell M22 (or M22) to fall below the temperature t1 is determined as the gaze time tb (N).
[0045]
In addition to this, when the gaze time tb (N) is equal to or longer than the predetermined time C3, when the driver determines that the driver is in a state of inattentiveness and determines YES in step 210, the process proceeds to step 121 and performs the inattentiveness control process. (Step 121) is executed. That is, an image for warning that the driver is not watching is displayed on the display 15, an audio output indicating the warning is output from the audio device 11, or vibration is given to the driver by the vibrator 16. Or
[0046]
When it is determined in step 210 that the gaze time tb (N) is shorter than the predetermined time C3 and NO is determined, the following determination processing (step 220) is performed. That is, it is determined whether or not a certain period of time tg or more has elapsed after the start of the impatience / inattention gaze detection process.
[0047]
Here, when it is determined that the predetermined period tg or more has not elapsed, the movement determination process (step 110), the determination width determination process (steps 120 and 130), the number of times of movement are performed until it is determined that the predetermined period tg or more has elapsed. Increment processing (Step 140), number-of-movements determination processing (Step 150), movement time calculation processing (Step 160), movement speed calculation processing (Step 170), movement speed determination processing (Step 180), gaze time calculation processing (Step 200) ), A gaze time determination process (step 210), and a fixed time elapsed determination process (step 220).
[0048]
Thereafter, in step 220, if it is determined that YES has elapsed for the predetermined period tg or more, the process proceeds to step 230, and the non-gazing determination routine shown in FIG. 3 is executed.
[0049]
In this non-attention gaze determination routine, it is determined whether or not the number of movements N is less than the reference number of times K1 (step 231). When the number of times of movement N is less than the reference number of times K1, it is determined that the number of times of movement N is too small in spite of the lapse of the fixed period tg or more, and YES is determined in step 231 in FIG. Thus, it is determined that the driver is in a state of inattentiveness.
[0050]
Thereafter, the process proceeds to step 233, where an image for warning that the driver is not watching is displayed on the display 15, an audio output indicating the warning is output from the audio device 11, or the vibrator 16 To give vibration to the driver.
[0051]
In step 231, when the number of movements N is equal to or greater than the reference number of times K1, the average moving speed Vave is obtained. For example, every time the driver's face has moved in the process of step 310, and the determination is YES, the moving speed is obtained, and the average value of the moving speed for each determination is obtained as the average moving speed Vave. When Vave is slower than the reference speed, the inattentiveness control process (step 233) is executed.
[0052]
In step 110 in FIG. 2, if the movement width L of the face is smaller than the reference width K0 and YES is determined in step 120 (L <K0), the inattentiveness control process (step 121) is executed. .
[0053]
As described above, according to the present embodiment, the movement state (movement width, number of movements, movement speed) of the face of the driver of the vehicle is detected using the temperature sensor 10 for measuring the temperature of each cell, and According to the detected moving state, it is estimated that the driver is impatient. For this reason, it is possible to estimate that the driver is impatient, without using a captured image of the driver's face. In addition, when it is estimated that the driver is impatient, music is generated, negative ions are generated, and a scent is generated, so that the driver's impatient is calmed down. For this reason, it can contribute to the safe driving of the driver.
[0054]
Further, in the present embodiment, the movement state (movement width, number of movements, movement speed) of the face of the driver of the vehicle is detected using the temperature sensor 10, and the driver is controlled in accordance with the detected movement state. It is presumed that the user is inattentive. Therefore, it is possible to estimate that the driver is in a state of inattentiveness without using a captured image of the driver's face. In addition, when it is estimated that the driver is in a gazeless state, a warning is issued, so that the driver can get out of the gazeless state and can concentrate on driving.
[0055]
Although it is possible to detect the moving state of the occupant by continuously imaging the occupant using a camera, it is necessary to identify the occupant in each detection area based on each captured image of the camera. Identification requires complex processing. On the other hand, in the present embodiment, the occupants in each detection area are identified by the temperature by using the infrared sensor 10, so that the occupants in each detection area can be identified without using complicated processing.
[0056]
Further, in the first embodiment, the built-in counter is incremented as the number N of times of movement for detecting inattentiveness or impatience of the driver every time the movement width determination processing (step 130) determines NO. Although the number of times of movement N is shown, instead of this, the built-in counter may be incremented and counted as the number of times of movement N every time YES is determined in the movement determination processing (step 110). .
[0057]
(2nd Embodiment)
In the above-described first embodiment, an example has been described in which it is estimated that the driver is in a state of inattentiveness due to the movement of the driver's face to the left and right. It is estimated that the driver is in a state of inattentiveness due to the movement (for example, when the driver feels drowsy).
[0058]
In the present embodiment, the controller 17 executes the inattentiveness detection process according to the flowchart shown in FIG. This inattentiveness detection processing is executed during driving. For example, when the ignition switch is turned on and the vehicle speed is equal to or higher than a predetermined speed, the execution is started.
[0059]
First, the built-in counter is reset (step 300), and based on the detection output of the infrared sensor 10, it is determined whether or not the driver's face has moved up and down (step 310).
[0060]
Specifically, after the temperature of the detection area of the infrared sensor 10 that is equal to or higher than the temperature t1 (which indicates the driver's face) decreases to the temperature t1 or lower, the lower area (or the upper area) of the area is determined. When the detected temperature of the region (a) rises to the temperature t1 or more and the detected temperature of the lower region maintains the temperature t1 or more for the time tr or more, the driver's face moves downward (or upward). It is determined that it has been done.
[0061]
For example, after the detected temperatures of the cells M42 and M52 shown in FIG. 8 change below the temperature t1, the detected temperatures of the cells M44 and M54 change to the temperature t1 or more, and the detected temperatures of the cells M44 and M54 become time tr. When the temperature t1 or more is maintained over the above, it is determined that the driver's face has moved from the detection areas of the cells M42 and M52 to the detection areas of the cells M44 and M54, and thus YES is determined in step 310. That is, it is determined that the driver's face has moved by the vertical dimension L2 (= 2 × L1) of the two cells.
[0062]
As described above, when it is determined that the driver's face has moved downward, is the face movement width L larger than the reference width M0 (for example, the width of one cell: L1)? Determine whether or not. Here, if YES is determined in step 310 as the movement width L of the face is larger than the reference width M0 (L ≧ M0), the process proceeds to step 121 and, for example, the driver is in a state of inattentiveness. The display 15 displays an image to warn the user of this, a sound output indicating the warning is output from the audio device 11, and the vibration is given to the driver by the vibrator 16.
[0063]
If it is determined in step 320 that the movement width L of the face is smaller than the reference width M0 and NO (L <M0), the process proceeds to step 340, and the counter value of the built-in counter is incremented as the number of movements N. (N = N + 1).
[0064]
Next, it is determined whether or not the number of movements N is equal to or greater than the reference number M1 (step 340). If the number of movements N is equal to or greater than the reference number M1, YES is determined. In this case, since it is estimated that the driver is in a state of inattentiveness, an inattentiveness control process (step 121) is executed.
[0065]
Further, in step 340, when it is determined that the number of movements N is less than the reference number of times M1, and the determination is NO, a movement time ta (N) required for movement of the driver's face is obtained. For example, when the driver's face moves from the detection area of the cells M42 and M52 to the detection area of the cells M43 and M53, after the detected temperature of the cell M42 (or M52) becomes equal to or lower than the temperature t1, the cell M43 ( Alternatively, the time until the detected temperature of M53) becomes equal to or higher than the temperature t1 is obtained as the movement time ta (N).
[0066]
Accordingly, a moving speed V (N) {= (L) / (ta (N))} is determined based on the moving time ta (N) and the moving width L, and the determined moving speed V (N) is If it is less than the reference speed M2, it is determined as YES in step 370. In this case, it is estimated that the driver is in a state of inattentiveness, and the inattentiveness control process (step 121) is executed.
[0067]
Further, in Step 370, if the determination is NO because the moving speed V (N) is equal to or higher than the reference speed M2, the process proceeds to Step 390, and the gaze time tb (N) is obtained.
[0068]
For example, when the driver's face moves from the detection area of the cells M42 and M52 to the detection area of the cells M43 and M53, the detection of the cell M43 (or M53) becomes equal to or higher than the temperature t1, and then the cell M43 ( Alternatively, the time until the detected temperature of M53) becomes lower than the temperature t1 is obtained as the gaze time tb (N), and when the gaze time tb (N) is equal to or longer than the predetermined time M3, the driver is in a state of inattention If it is determined as YES in step 400, the inattentiveness control process (step 121) is executed.
[0069]
Also, in step 400, when the gaze time tb (N) is shorter than the predetermined time M3, it is determined as NO, and it is determined whether or not a certain period of time tg has elapsed after the start of the inattention gaze detection processing ( Step 220). Here, when it is determined that the predetermined period tg or more has not elapsed, the movement determination process (step 310), the determination width determination process (step 320), and the number of movement increment process are performed until it is determined that the predetermined period tg or more has elapsed. (Step 340), moving time calculation processing (Step 350), moving speed calculation processing (Step 360), moving speed determination processing (Step 370), gaze time calculation processing (Step 390), and gaze time determination processing (Step 400). Do.
[0070]
As described above, according to the present embodiment, the vertical movement state (movement width, number of movements, and movement speed) of the face of the driver of the vehicle is detected using the temperature sensor 10 and the detected state is detected. Based on the moving state, it is estimated that the driver is not watching. Therefore, similarly to the first embodiment, it is possible to estimate that the driver is in a state of inattentiveness without using a captured image of the driver's face. In addition to this, when it is estimated that the driver is not watching, a warning is issued, so that the driver can concentrate on driving.
[0071]
In the second embodiment, the number of movements N for detecting the driver's inattentiveness is determined by incrementing the built-in counter every time the movement width determination process (step 330) determines NO. However, instead of this, the built-in counter may be incremented and counted as the number of movements N each time YES is determined in the movement determination processing (step 310).
[0072]
Further, the first and second embodiments may be implemented in combination.
