OPERATION OF DROWSINESS DETECTION SYSTEM
Preparation state
The system is started and starts the self-diagnosis when the starting switch is at the ON position. After the selfdiagnosis
is completed and the system is started normally, the operation notification sound (Three short beeps)
occurs, and the status goes to the normal operation state.
When a failure is sensed
When the Driver Status Monitor sensed
• The failure notification sound occurs from the notification sound speaker.
• Keep the preparation state.
When other than the Driver Status Monitor sensed
• The failure code is shown on the machine monitor.
• Keep the preparation state.
Normal operation state:
The system senses no abnormality and operates normally. The state is as follows.
• The drowsiness detection system ready lamp lights up.
• The operation notification sound and drowsiness alarm buzzer do not occur.
• If a failure is sensed during the normal operation state, the status changes to the preparation state.
Alarm state:
When short time sleep and drowsiness are sensed
The system judges that the operator sleeps for a short time or the drowsiness of operator is above the specified
level during the travel. The state is as follows.
• The drowsiness detection system ready lamp flashes.
• The alarm notification sound and drowsiness alarm buzzer occur.
• If a failure is sensed during the alarm state, the status changes to the preparation state.
When inattentive driving and loss of balance are sensed
The system judges that the operator looks aside or loses the balance during the travel. The state is as follows.
• The drowsiness detection system ready lamp flashes.
• The alarm notification sound occurs.
• If a failure is sensed during the alarm state, the status changes to the preparation state.
You can release the alarm state with one of the conditions that follow.
• When the system judges that the operator has no more short time sleep, inattentive driving, loss of balance,
and drowsiness.
• When the travel speed becomes below 1km/h.
