  As shown in FIG. 1, the motorcycle 12 includes a front fork 14 that pivotally supports a front wheel WF and a head pipe 18 that supports a steering wheel 16 connected to the front fork 14 in a steerable manner at the front end. A unit swing engine UE that supports the wheel WR at the rear end is supported so as to be vertically swingable at a middle portion in the front-rear direction of the vehicle body frame F. The vehicle body frame F is disposed in front of the unit swing engine UE, A radiator 22 disposed behind the fuel tank 20 and a battery 24 are mounted. In addition, a riding seat 30 having a front seat 26 and a rear seat 28 and configured in a tandem shape is disposed at the rear portion of the vehicle body frame F. Further, a synthetic resin vehicle body cover 32 that covers the vehicle body frame F, the front portion of the unit swing engine UE, the fuel tank 20 and the radiator 22 is attached to the vehicle body frame F.

  The unit swing engine UE is a water-cooled engine (driving source) E having a cylinder axis substantially horizontal, and a belt type that continuously transmits the output of the engine E to a rear wheel WR by a transmission belt and a pulley. The continuously variable transmission M drives the movable pulley on the crankshaft side in response to the operation of the electric motor 34 for shifting and changes the gear ratio steplessly. Is.

  The transmission case 36 of the continuously variable transmission M is connected to the left side of the crankcase 38 of the engine E so as to protrude from the engine E to the left side, and extends to the left side of the rear wheel WR. A front end portion of a swing arm (not shown) is coupled to the right side of the crankcase 38, and the rear wheel WR is pivotally supported between the rear end portion of the transmission case 36 and the rear end portion of the swing arm.

  The rear end of the body frame F is connected to the upper ends of a pair of left and right rear cushions 40. The lower ends of both rear cushions 40 are connected to the rear end of the transmission case 36 and the rear end of the swing arm. Is done.

  A storage box 42 for storing articles is provided below the riding seat 30 and extends from below the front end of the riding seat 30 to the vicinity of the upper portion of the rear cushion 40. The storage box 42 also serves as a lid that covers the upper surface of the riding seat 30, and the interior space is exposed by lifting the riding seat 30 to the right side.

  The front cowl 44 of the vehicle body cover 32 includes a transparent wind screen 46 at an upper portion, and a meter panel 48 is provided between the wind screen 46 and the handle 16. The handle 16 is provided with a pair of left and right rearview mirrors 50. The inner cover 52 includes a leg shield 54 that covers the front part of the driver's legs, and a step holder 56.

  As shown in FIG. 2, the meter panel 48 includes a left tachometer 60, a right speedometer 62, a warning display unit 64 provided slightly below the center, and blinker lamps 66 a and 66 b provided below and to the left and right. A camera (imaging unit) 68 and an infrared LED (light projecting unit) 70 provided on the warning display unit 64 and arranged in parallel, and a control unit 72 provided therein. The speedometer 62 includes an odometer 74.

  The camera 68 is a CCD camera or a CMOS camera, for example, and is directed in this direction in order to image the position of the driver's head. The position of the driver's head here is the position of the head when the driver is driving in a correct posture (during normal driving). The camera 68 has a wide imaging field of view in consideration of the difference in the sitting height of the driver in order to reliably image the driver's head. The image captured by the camera 68 is supplied to the control unit 72. The camera 68 can receive light in the infrared region.

  The infrared LED 70 is a light projecting unit that projects infrared light (for example, near infrared light having a wavelength of 700 nm to 2500 nm) under the action of the control unit 72, and projects light at least toward the driver's head. The orientation is set to do.

  Next, the vehicle drive control apparatus 10 according to the present embodiment will be described.

  As shown in FIG. 3, the vehicle drive control device 10 includes a camera 68, an infrared LED 70, and a control unit 72. The control unit 72 includes a camera control unit 100 that controls the camera 68, an image temporary storage unit 102 that temporarily stores an image obtained by the camera 68, and a nonvolatile readable / writable storage unit that stores predetermined data. 104 a to 104 c, a comparison unit 106 that compares the image in the temporary image storage unit 102 with the data in the storage units 104 a to 104 c, and a light projection control unit 108 that controls the infrared LED 70.

  Image information (reference information) of the helmet 80 during normal driving of the driver D is recorded in the storage units 104a to 104c. As this information, an image obtained by imaging the position of the helmet 80 of the driver D may be stored as it is, or may be stored as a converted image (two-dimensional information) subjected to image processing such as predetermined contour extraction. The shape, position, and the like of the helmet 80 in the image may be stored as numerical data (reference information). These reference information may be two-dimensional information. In the following example, a converted image subjected to image processing such as contour extraction is recorded.

  Note that three of the storage units 104a to 104c are independent storage units, and information on up to three helmets 80 owned by the driver can be individually stored. Further, more storage units (104d, 104e,...) May be provided, and information related to some typical helmet shapes may be recorded in advance.

  The comparison unit 106 of the control unit 72 is connected to an ignition control unit 112 that controls ignition of the spark plug 110, a fuel injection control unit 116 that controls the fuel injector 114, and a starter control unit 120 that controls the starter motor 118. Has been.

  The comparison unit 106 compares the image obtained by the camera 68 with the information in the storage units 104a to 104c, and outputs a signal “OK” that permits the operation of the engine E when the image corresponds to the information. When the image does not correspond to the information, a signal “NG” for prohibiting the operation of the engine E is output. These signals are supplied to the ignition control unit 112, the fuel injection control unit 116, and the starter control unit 120.

  The ignition control unit 112 ignites the air-fuel mixture by the spark plug 110 when the signal “OK” is received, and does not perform the ignition when the signal “NG” is received.

  The fuel injection control unit 116 performs fuel injection by the fuel injector 114 when the signal “OK” is received, and does not perform fuel injection when the signal “NG” is received.

  The starter control unit 120 rotates the starter motor 118 when a predetermined starter switch is pressed while receiving the signal “OK”, and regardless of the state of the starter switch when receiving the signal “NG”. The starter motor 118 is not rotated.

  Since the signal “NG” of the comparison unit 106 is supplied to the ignition control unit 112 and the fuel injection control unit 116, when the signal “NG” is output, not only the start of the engine E is prohibited but also the start is already started. The running engine E can also be stopped.

  The comparison unit 106 can detect the vehicle speed V from the vehicle speed sensor 122, is connected to the buzzer 124, can generate a predetermined alarm sound, and can measure time based on the timer 126. The vehicle drive control device 10 is supplied with electric power from the battery 24 via a key switch (not shown) or the like.

  Next, the operation of the vehicle drive control device 10 configured as described above will be described. First, the initial storage process shown in FIG. 4 is performed. This process is mainly performed under the action of the comparison unit 106. In addition, although infrared LED70 shall always be lighted, you may light according to the imaging timing of the camera 68 depending on design conditions.

  If it is determined in step S1 that the engine E is operating, the process proceeds to step S2.

  In step S2, it is confirmed whether or not a predetermined recording switch (not shown) is pressed. When the recording switch is pressed, the process proceeds to step S3. When the recording switch is not pressed, the process returns to step S1.

  In step S <b> 3, the image 150 (see FIG. 5) is captured from the camera 68 into the image temporary storage unit 102. At this time, since the infrared LED 70 is lit, it is possible to take an image even in a dark place such as at night. Since infrared rays are not recognized by the driver, the driver is not unnecessarily aware at the time of starting and driving.

  In step S4, feature extraction of the helmet 80 portion is performed from the image 150. For example, after performing an appropriate contour extraction, a shape portion close to the reference arc of radius R may be extracted, or a portion having a higher degree of coincidence than a predetermined typical pattern may be extracted. As a result, a region 152 is extracted from the image 150 of FIG. 5 and is obtained as helmet contour reference data 154a in which the contour feature as shown in FIG.

  At this time, if a portion corresponding to the helmet 80 cannot be extracted, an alarm process by the buzzer 124 may be performed.

  In step S5, the helmet contour reference data 154a obtained in step S4 is stored in the storage unit 104a. As shown in FIG. 6A, the helmet contour reference data 154a is data corresponding to a full-face helmet. The vehicle drive control device 10 can further store a plurality of data. For example, as shown in FIG. 6B, helmet outline reference data 154b corresponding to a jet type helmet is stored in the storage unit 104b. As shown in FIG. 6C, helmet contour reference data 154c corresponding to an off-road helmet can be stored in the storage unit 104c. The storage units 104a to 104c are non-volatile, and the stored data is saved even when the power is turned off. After step S5, the process returns to step S1.

  Next, processing contents as a first example of the vehicle drive control device 10 at the time of normal engine start will be described.

  In step S101 in FIG. 7, the vehicle drive control device 10 is activated by turning on the key switch. In the initial state, the comparison unit 106 outputs the signal “NG” (the same applies to the second example).

  In step S <b> 102, the image 150 (see FIG. 5) is captured from the camera 68 into the image temporary storage unit 102. Also in this case, since the infrared LED 70 is lit as in step S3, it is possible to take an image even in a dark place such as at night. At this time, since the camera 68 images in a direction substantially corresponding to the normal position of the helmet 80, if the driver does not wear the helmet 80, an image 156 shown in FIG. The driver's head is imaged. Further, if the driver does not wear the helmet 80 correctly, an image is captured as shown in an image 158 shown in FIG. 8B. Furthermore, if the driver is not properly seated on the seat 26, for example, standing on the side, only a part of the helmet 80 is captured or not captured at all, as in the image 160 shown in FIG. 8C. Become.

  In step S103, as in step S4, feature extraction of the portion of the helmet 80 is performed from the image 150. The comparison contour data 156a shown in FIG. 9B is obtained for the image 156 shown in FIG. 8A, and the comparison contour data 158a shown in FIG. 9B is obtained for the image 158 shown in FIG. 8B, as shown in FIG. 8C. For the image 160, comparative contour data 160a shown in FIG. 9C is obtained. When the helmet 80 is correctly worn in the correct posture, the same data as the helmet contour reference data 154a shown in FIG. 6A is obtained for the image 150 shown in FIG.

  Incidentally, as shown in FIG. 6A, a full-face helmet 80 is usually provided with a front shield 170 that can be opened and closed, and the front shield 170 is often lifted upward to be opened. The vehicle drive control device 10 may perform a process of removing the front shield 170 from the obtained image so that the helmet 80 is not mistakenly identified between the closed state and the opened state of the front shield 170. This process utilizes, for example, the fact that the front shield 170 is transparent or translucent, specifies the front shield 170 portion from the luminance, saturation, chromaticity, etc., or creates a gap (not shown) in the upper part of the helmet 80. It is only necessary to identify and remove the portion of the front shield 170 using the fact that

  Of course, the storage process (see FIG. 4) may be performed for the closed state and the opened state of the front shield 170, respectively.

  In step S104, the obtained comparison contour data and helmet contour reference data 154a to 154c (see FIGS. 6A to 6C) recorded in advance are compared in order, and when both correspond to each other, the process proceeds to step S105. If not supported, the process proceeds to step S106. The correspondence between both indicates, for example, that the degree of coincidence exceeds a predetermined threshold based on a predetermined degree of coincidence determination (pattern matching or the like), and the non-correspondence indicates that the degree of coincidence is less than the predetermined threshold.

  When the helmet 80 is correctly worn in the correct posture, the same data as the helmet contour reference data 154a is obtained as the comparison contour data, so that the degree of coincidence is high when both are compared, and the process proceeds to step S105. become.

  In addition, when the driver wears a pre-stored off-road helmet, a low match is obtained when compared with the helmet contour reference data 154a first and when compared with the helmet contour reference data 154b for the second time. However, when compared with the helmet contour reference data 154c (see FIG. 6C) for the third time, a high degree of coincidence is obtained, and the process proceeds to step S105.

  In addition, about the helmet outline reference data 154a-154c, the frequency | count that matched with comparison outline data is counted and hold | maintained, and it is good to compare it in order with the said frequency | count from the next time. For example, if the frequency of wearing the jet helmet for the driver is high, the number of counts for the helmet contour reference data 154b is increased, and the comparison processing for the helmet contour reference data 154b is performed first. The processing time can be shortened.

  On the other hand, when the driver does not wear the helmet 80 and is not worn correctly or not in the correct position, the comparison contour data 156a, 158a or 160a (see FIGS. 9A to 9C) and helmet contour reference data 154a, 154b, and 154c are sequentially compared. In either case, the degree of coincidence is considerably low, and the process moves to step S106.

  In step S <b> 105, as an engine operation permission process, the comparison unit 106 outputs a signal “OK” to the ignition control unit 112, the fuel injection control unit 116, and the starter control unit 120. Therefore, thereafter, the engine E can be started by pressing a predetermined starter switch. In addition, a warning stop process performed in step S107 is performed.

  On the other hand, in step S106, the comparison unit 106 outputs a signal “NG” to each control unit as an engine operation prohibition process. Therefore, after that, even if a predetermined starter switch is pressed, the engine E does not start. The engine operation prohibiting process in step S106 (and step S210) is a broad warning process.

  In step S107, a warning sound by the buzzer 124 is generated as warning processing. As a result, it is possible to prompt the driver to wear the helmet 80 correctly and to ride in the correct posture. The warning process may be performed by visual means (warning lamp or the like) or auditory means (sound, sound).

  After step S107, the process returns to step S102, and a series of comparison confirmation processing is continued. Therefore, the buzzer 124 is stopped and the engine E can be started when the driver correctly wears the helmet 80 in the correct posture.

  Next, as a second example of the processing contents of the vehicle drive control device 10, a case where a comparison confirmation process is performed at the time of engine start and after the start will be described. Here, it is assumed that the camera 68 continuously captures images after the engine E is started.

  Steps S201 to S205 in FIG. 10 are the same processes as steps S101 to S105. After step S205, the process proceeds to step S206.

  In step S206, the timer 126 is reset. The timer 126 is always up-counted by appropriately dividing a clock (not shown), and by resetting in step S206, the time can be counted as zero. In addition, a warning stop process performed in step S208 is performed.

  After step S206, the process returns to step S202. That is, steps S202 to S206 form a loop, and even after the engine is started, if the driver correctly wears the helmet 80 in the correct posture, the process is continued based on the loop. In addition, the timer 126 is reset every moderately short time (S206).

  On the other hand, if the determination in step S204 is “No”, the process proceeds to step S207.

  In step S207, the value of the timer 126 is confirmed, and it is confirmed whether or not the time T1 has elapsed. This reference time is a reset time in step S206. When the time T1 has not elapsed, the process returns to step S202 to continue the processing, and when the time T1 has elapsed, the process proceeds to step S208.

  When step S204 is first executed in the process shown in FIG. 10 (that is, immediately after key-on) and the determination is “No”, the comparison unit 106 outputs the initial signal “NG”. Therefore, starting of the engine E is prohibited.

  In step S208, warning processing is performed. This is the same processing as step S107 described above.

  By the way, once step S205 is executed, the comparison unit 106 outputs a signal “OK”, and when the determination in step S204 becomes “NG” during the loop processing after the engine E is started, Due to the action of the determination process in S207, step S208 is not executed immediately. Therefore, for example, during cornering, the driver may temporarily move the head (that is, the portion of the helmet 80) out of the field of view of the camera 68 because it is necessary to move the weight. No unnecessary warning is generated.

  In step S209, the value of the timer 126 is confirmed, and it is confirmed whether or not the time T2 (T2 ≧ T1) has elapsed. This reference time is a reset time in step S206. When the time T2 has not elapsed, the process returns to step S202 to continue the process, and when the time T2 has elapsed, the process proceeds to step S210.

  In step S <b> 210, the comparison unit 106 outputs a signal “NG” to each control unit as an engine operation prohibition process. This is the same processing as step S106 described above.

  According to such a process, it is possible to make an effort to maintain the normal operation not only at the start but also at the time of traveling. Even after the warning process (step S208) or the engine operation prohibition process (step S210) is executed, the loop process of steps S202 to S206 is executed when the driver correctly puts on the helmet 80 in the correct posture. E can be restarted.

  In step S209, the vehicle speed V supplied from the vehicle speed sensor 122 is monitored, and as a condition for moving to step S210, the motorcycle 12 is stopped (including substantially stopped). May be. Accordingly, after starting, rerunning can be prohibited when the vehicle is stopped in the case of non-regular operation.

  In the above example, the helmet 80 is compared based on the contour, but a plurality of marks arranged in a predetermined manner may be provided on the helmet 80, and the helmet 80 may be compared based on the marks.

  For example, as shown in FIG. 11, three infrared reflecting seals (infrared reflecting means) 82 are attached to the helmet 80 at the left and right positions of the head and the central jaw position. One control unit 72 stores such arrangement information (reference information) in the storage units 104a to 104c in advance, and performs comparison processing. By providing the infrared reflective seals 82 at such three points that are moderately separated, the control unit 72 can accurately and reliably recognize the position and orientation of the helmet 80 based on the image obtained from the camera 68. In addition, the inverted triangular arrangement of two in the upper left and right and one in the lower center has been confirmed to have an effect reminiscent of the person's face to the opponents (driver and pedestrian), and a warning effect can be expected.

  The infrared reflective seal 82 is inexpensive and lightweight, and can be attached by the driver himself based on a predetermined rule. For example, the infrared reflective seal 82 can be attached to a plurality of helmets 80 owned. The infrared reflective seal 82 naturally has no power consumption. The infrared reflective seal 82 does not need to be very large and does not impair the design of the helmet 80.

  It is desirable to provide three or more infrared reflective seals 82 for detecting the position and orientation of the helmet 80. For example, as shown in FIG. 12, the infrared reflective seal 82 may be affixed to the head center position and the left and right jaw positions.

  As described above, according to the vehicle drive control device 10 according to the present embodiment, the image 150 by the camera 68 that directs the direction of the driver's head as the specific location, and the image of the helmet 80 during the normal driving of the driver. By comparing with the information, it can be determined whether or not the driver is in a normal driving state, and the operation of the engine E of the motorcycle 12 is permitted or prohibited based on the determination result. be able to.

  In the vehicle drive control device 10, no special unit is required on the helmet 80 side, there is no risk of running out of the battery, and the helmet 80 does not increase in weight. There is no particular restriction when replacing the helmet 80.

  The vehicle to which the vehicle drive control device 10 is applied is not limited to the motorcycle 12, but may be a four-wheeled vehicle (for example, a competition vehicle in which helmet wearing is encouraged). The drive source of the vehicle is not limited to the engine E, and may be a motor, for example.

  The object to be confirmed by the camera 68 is not limited to the helmet 80, and for example, a protector or boot that is to be worn by driving an off-road competition vehicle may be the confirmation object.
