Show.

  In FIG. 2, first, in step S101, the non-wake state detection apparatus 1 measures the opening degree of the driver's heel as described above, and calculates the driver's arousal level.

  In step S102, it is determined whether or not the driver's arousal level is reduced.

  If the awakening level is greater than or equal to the predetermined value in step S102, it is determined that the driver's awakening level has not decreased and the flow proceeds to step S103, and the detection signal output to the driving operation control device body 5 is not performed. Returns to step S101.

  If the arousal level is less than or equal to the predetermined value in step S102, it is determined that the driver's arousal level is decreasing, the flow proceeds to step S104, a detection signal is output to the driving operation control device body 5, and the flow Return to S101.

  As described above, the non-wakefulness detection device 1 continuously calculates the driver's alertness, and outputs a detection signal to the driving operation control device main body 5 only when the alertness becomes a predetermined value or less.

  In FIG. 3, first, in step S201, it is determined whether or not the non-wake state detection device 1 outputs a detection signal. When the non-wake state detection device 1 outputs a detection signal, the flow proceeds to step S202. If the non-wake state detection device 1 does not output a detection signal, the flow returns to step S201.

  In step S202, after the driving operation control device body 5 holds the drive signal value to the steering wheel drive device 3C output from the steering control unit 3B at that time and outputs it to the steering wheel drive device 3C, the flow proceeds to step S203. Migrate to

  In step S203, the driving operation control device main body 5 outputs an operation signal to the wakeful stimulus generating device 2, and the wakeful stimulus generating device 2 generates a wakeful stimulus, for example, an alarm sound to the driver, and the flow proceeds to step S204. To do.

  In step S204, it is determined again whether or not the non-wake state detection apparatus 1 outputs a detection signal. When the non-wake state detection device 1 outputs a detection signal, the subject is in the non-wake state, the flow returns to step S204, and the generation of the wake-up stimulus is continued. If the non-awake state detection device 1 does not output a detection signal, the flow proceeds to step S205 when the driver has reached the awake state.

  In step S205, the operation signal output from the driving operation control device body 5 to the wakeful stimulus generator 2 is stopped to stop the wakeful stimulus generated in the wakeful stimulus generator 2, and the flow goes to step S206. Transition.

  In step S206, it is determined from the value of the steering angle signal whether or not the driver is intentionally operating the steering.

  If the value of the steering steering angle signal exceeds the predetermined steering angle signal value in step S206, it is determined that the driver is intentionally operating the steering, the flow proceeds to step S208, and the drive signal value The hold is released and the steering control is returned to the normal control.

  If the steering angle signal value of the steering is less than or equal to the predetermined steering angle signal value in step S206, it is determined that there is no intentional steering operation by the driver, and the flow proceeds to step S207.

  In step S207, the loop is repeated until a predetermined time has elapsed since the driver reached the awake state. This period corresponds to a period in which the driver changes from the unawake state to the awake state and a steering operation may occur due to unconscious body movement. If the predetermined time has not elapsed, the flow returns to step S206. After the predetermined time has elapsed, the flow moves to step S208.

  In step S208, the driving operation control device main body 5 that holds the drive signal value output by the steering control unit 3B and outputs it to the steered wheel drive device 3C when the awakening level is lowered releases the hold of the drive signal value. Then, the control is returned to the normal control in which the drive signal output from the steering control unit 3B is output to the steering wheel drive device 3C as it is.

  By the above flow, when the driver's arousal level is reduced, the steering operation is invalidated and then the driver is awakened by stimulating the driver's arousal, and the driver returns from the non-awake state to the awake state. In some cases, the awakening stimulus is stopped and the steering control is returned to the normal control after a predetermined time has elapsed from the time when the state returns to the awakening state.

  With this operation, when the driver returns from the awake state to the awake state by the awakening stimulus, the steering wheel is not driven even if the steering operation is performed by the driver's unconscious body movement. No change of course.

  If the steering angle signal becomes equal to or higher than the predetermined steering angle signal value during the period when the steering operation is invalid, it is determined that the driver is consciously operating the steering to ensure safety, Since the steering control is returned to the normal state, it is possible to cope with the steering operation of the kite.

  In FIG. 4, first, in step S301, it is determined whether or not the non-wake state detection device 1 outputs a detection signal. When the non-wake state detection device 1 outputs a detection signal, the flow proceeds to step S302. If the non-wake state detection device 1 does not output a detection signal, the flow returns to step S301.

  In step S302, after the driving operation control device body 5 outputs to the throttle drive device 4C an acceleration signal for which the throttle opening is a predetermined value, for example, zero regardless of the value of the acceleration signal received from the accelerator control unit 4B. The flow moves to step S303.

  In step S303, the driving operation control device main body 5 outputs an operation signal to the wakeful stimulus generating device 2, and the wakeful stimulus generating device 2 generates a wakeful stimulus, for example, an alarm sound, to the driver, and the flow proceeds to step S304. To do.

  In step S304, it is determined again whether the non-wake state detection device 1 outputs a detection signal. When the non-wake state detection device 1 outputs a detection signal, the subject is in the non-wake state, the flow returns to step S304, and the generation of the wake-up stimulus is continued. If the non-awake state detection device 1 does not output a detection signal, the flow proceeds to step S305 in a state where the driver has reached the awake state.

  In step S305, the operation signal output from the driving operation control device body 5 to the wakeful stimulus generator 2 is stopped to stop the wakeful stimulus generated in the wakeful stimulus generator 2, and the flow goes to step S306. Transition.

  In step S306, the loop is repeated until a predetermined time has elapsed since the driver reached the awake state. This period corresponds to a period during which the driver may change from an unawake state to an awake state and an accelerator operation due to unconscious body movement may occur. If the predetermined time has not elapsed, the flow returns to step S306. After the predetermined time has elapsed, the flow moves to step S307.

  In step S307, the driving control device body 5 that has output the acceleration signal that causes the throttle opening to zero to the throttle driving device 4C at the time when the arousal level decreases decreases the acceleration signal that causes the throttle opening to become zero. The output is canceled, and the control is returned to the normal control in which the acceleration signal received from the accelerator control unit 4B is output to the throttle drive device 4C as it is.

  By the above flow, when the driver's arousal level is reduced, the accelerator operation is invalidated and then the driver is awakened by stimulating the driver's arousal, and the driver returns from the non-awake state to the awake state In some cases, the arousal stimulation is stopped, and the accelerator control is returned to the normal control after a predetermined time has elapsed from the time when the wakefulness is restored.

  Because of this movement, when the driver returns from the awake state to the awake state due to the arousal stimulus, the throttle is not driven even if the accelerator operation is performed by the driver's unconscious body movement, so the acceleration by the unconscious accelerator operation Is not accompanied.

  In the above embodiment, the non-wake state detection device 1 uses means for measuring the driver's eyelid opening to detect a decrease in the alertness level. Any means capable of detecting a decrease in the driver's arousal level, such as a means for measuring a decrease in the number of blinks associated with a reduction in the arousal level, a means for detecting meandering of the vehicle due to a reduction in the arousal level, etc. good.

  Further, the arousal stimulus generated when the arousal level is reduced is not limited to the alarm sound, and may be anything that encourages the driver to awaken, such as generation of a vibration element or scent incorporated in the seat.
