Driver's status monitoring

The most effective driver monitoring systems are Attention Assist, Driver Alert Control and Seeing Machines. Their goal is to discover and report changes in the human body.

Monthly road or long-lasting trips to car especially at night lead to the driver's fatigue. As a result, its reaction decreases, and fatigue increases. This leads to the fact that the body does not withstand the load, and the driver simply falls asleep. This leads to a numerous serious accident.

In order to avoid such cases, systems have invented that observe and control the level of driver fatigue. You can do this using 3 indicators. In the first case, the driver's actions are observed, then the movement of the car, and finally the driver's view.

Attention Assist.

The ATTENTION ASSIST system monitors using several parameters and elements. This system is embedded in the car of the German brand Mercedes-Benz. The Attention Assist system consists of several sensors, each of which they are responsible for a special fatigue rate. These are such sensors, such as steering wheels, engine or braking system. One of the main is the control unit sensor.

It monitors the physical condition of the driver for many indicators. First of all, he controls the driving manor, namely speed. The following indicators serve as the conditions in which the car is moving. Here is meant, the time of the duration of the trip and when it happens at what time of day.

The brake system and stealless switches belong to the managerial system, which is also controlled by the system. Finally, the acceleration is monitored, namely late and longitudinal.

Following the current state, the system compares it with the original one. If the indicators signal a significant deviation from the norm, the audio signal is turned on and the ATTENTION Assist: Pause message is displayed on the screen bar, warning the driver.

The signal is notified every 15 minutes in case of ignoring the warning. The system is activated at a speed of 80 km / h. Analysis of speed, maneuverability and removal of other parameters occurs 30 minutes after the start of the movement, as most often it is as much time it is required to move to long distances.

DRIVER ALERT CONTROL (DAC)

The next DRIVER Alert Control control system was created by the Swedish Volvo Automobile Company. Here the principle is built on tracking the condition of the driver through the verge of car movement. To do this, a special camcorder is built into the Volvo car, which monitors the driving character on the road. An assessment of the trajectory and its changes using the steering wheel sensor and monitor road strips. The second video camera monitors the external state of the driver, namely the movement of the eyes.

If the state of overwork is recorded, the system notifies the driver using the Driver Alert signal and the message. Time for a Break. " The system begins to act at a speed of 60 km / h.

Seeing Machines.

The last system controlling the driver's condition is a Seeing Machine embedded in the British brand of Jaguar. It is noteworthy that this technology is applied not only in the case of driving a car, and in other areas. A system was built solely on monitoring the external physical condition of the driver. The built-in camera fixes the position of the eyes and their direction.

In case of rejection of the indicator from the norm, the system obsesses the fatigue and the likelihood to fall asleep by the wheel using a signal and a special message.

Perfection of this technology is that it is intensified even if the driver is in sunglasses. Also, this system includes additional parameters. For example, the system is fixed in the absence of attention to the rearview mirror. In this case, the driver comes a reminder of this action.
