SLEEPING – DRIVER AUTO DETECTOR

Introduce.
 
Sleepy driver during the driving inevitably leads to hardest consequences for both the driver and his passengers, often for quite strangers. Unmanaged car, weighing 2-3 tons, traveling at a speed of 50-80 km per hour is able to mess things up a lot of troubles.

Reasons leading to falling asleep behind the wheel as follows
1. Fatigue. Driver has been  at the wheel for long enough (typical for professionals) or he  has performed  the  monotonous heavy work the day before ride (typical for amateurs). 
2. Alcohol intoxication. Even small "allowed" dose of alcohol of 0.3 ppm can dramatically increase the likelihood of falling asleep of the driver.
3. Monotonous road. Road without any features, wide, with the same view on the roadside, especially familiar, where "anything can happen" by itself has a calming effect and begins to put to sleep.
4. Riding at an inopportune time, at night.
5. Riding after a hearty lunch. Large amount of food in the stomach causes an outflow of blood from the brain. The brain begins to "dozing."
6. Taking medication. There is a large list of drugs reducing reaction, calming the nervous system, relieves pain. Accordingly, increases the likelihood of falling asleep.
 
List of reasons could be continued and individualize. Reasons usually act collectively, superimposed on one another, which greatly increases the likelihood of falling asleep.
 
Signs of falling asleep behind the steering wheel. If you notice them, it's time to take urgent action.
1. Vigilance reducing. Thoughts begin to wander far from the topics quite a trip, come back memories …
2. Reducing of attention. You stop understand the readings, you stop notice the  signs, intersections, landscape.
3. Lack of concentration and tension in the hands and feet. On the straights you want to steer with "one finger". No desire to make sharp movements, general lethargy.
4. Eyes become "heavy" and  blink time is greatly increasing. You want to keep your eyes closed "at least a few seconds."
 
The driver may not be fully aware of the fact that he starts dozing.
The behavior of the driver who starts to fall asleep.
1. Speech becomes less intelligible. The answers are following with a delay.
2. The movements became sluggish.
3. The driver nods, then lowers his head forward, throws back a bit ago.
4. The driver rubs often his hand over his face, He rubs his forehead, cheeks, neck, trying to embolden himself.
5. The driver keeps   his distance with ahead  traveling cars not clearly, approaching close to them or  much behind them without  a particular reason. He moves with unstable speed.
6. The driver begins to "lose" the car.  From time to time he pulls over to the roadside or to the oncoming lane.
 
The essence of the SLEEPING – DRIVER AUTO DETECTOR
The system is intended to increase driver safety on long trips, when there is a risk of falling asleep behind the wheel. The main feature of the system is to recognize the situation, when the driver starts to fall asleep. At this point, the system activates the action to draw the attention of the driver to stimulate him.
In a situation when the awakening of  the driver is not  possible, or he suffers from chronic diseases such as heart attack, the car autopilot will gradually slow down the movement of the car holding the appropriate path, and will pull over at the next safe side, will switch on the  emergency lights and will notifies ambulance.
 
Who will be interested in this system?
It will be a system primarily for business people traveling on long trips as well for drivers who are forced to drive after a sleepless night. It will be very useful for people who care about not only them safety, but above safety of all  family and passengers.
 
How does it work?
The monitoring of the driver condition will be realized using  the vision sensors,  the pulse tactile sensors, the electrical skin conductance sensors and brain activity sensors.
If the driver is in good and healthy condition and pays all the attention to the road - the system is in passive mode.
At a time when there is the possibility of reducing or deterioration of attention, or by using the synchronization of the sensor system, the system detects drowsiness - automatically switches to active mode.
In this mode, the system attempts to awaken the driver, and is ready to take control of the vehicle on a short time.
Under the "taking of control" we mean the autopilot function, whose task is to keep the car on the road at the correct path to eliminate any accidents caused by driving off the car on the opposite lane, or completely pull over the road.
Awakening of the driver will be realized with a few options, the choice of which will be possible from the appropriate menu in the on-board computer. There you can choose the intensity of the action too.
 
Examples of possible actions
• Sound signal.
• Poor (safe) electric shock.
• Strong, pulsating vibrations.
 
The equipment of the “sleeping – driver auto detector”

Inside sensors
 
 

 
1. Vision sensor. It is located opposite the driver. With the help of neural network algorithms sensor detects the movement of the driver who starts to doze off (nodding of the head, long shut-eye).
2. Pulse tactile sensors. They are built into the steering wheel of the car. They measure the pulse of the driver fixing the slowing of heart palpitations due to  decreasing of the physical activity.
3. Electrical skin conductance sensors. They are built into the steering wheel of the car. 
They measure the electrical conductivity of the skin. Increasing of electric conductivity indicates a reduction in skin resistance due to the decreasing of physical activity.
4. Brain activity sensor. It is located above the head of the driver. The device determines if driver is awake or sleeping.
 
Having multiple sensors eliminates the  false alarms and in additional allows  to determine  such deviations of  normal condition of the driver as a heart attack, loss of consciousness, etc.
 
Outside sensors
 

 
1. Vision sensors. They are located on four sides of the car body. They monitor  the status of the road. They are the “eyes” of the system in the case when system takes control of the car.
 
Wake-up devices
 

 
1. Sound signal. Uses the car's audio system
2. Poor (safe) electric shock. Electrodes built into the steering wheel of a car.
3. Strong, pulsating vibrations. Vibration motors built into driver's seat.
 
Autopilot
Actuators built into the steering system of car.
 
Ambulance call
Automatic call for ambulance with reporting of the driver data and  vehicle position from GPS.
