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

A monotonous road or long car journeys, especially at night, lead to driver fatigue. As a result, his reaction is reduced, and fatigue increases. This leads to the fact that the body cannot withstand the load, and the driver simply falls asleep. This leads to numerous serious accidents.
In order to avoid such cases, they came up with systems that monitor and control the level of driver fatigue. This can be done using 3 indicators. In the first case, the actions of the driver are observed, then the movement of the car, and finally the look of the driver.
Attention Assist
The Attention Assist system performs control using several parameters and elements. This system is built into the car of the German Mercedes-Benz brand. The Attention Assist system consists of several sensors, each of which is responsible for a specific indicator of fatigue. These are sensors such as the steering wheel, engine or brake system. One of the main ones is the control unit sensor.
He monitors the physical condition of the driver for many indicators. First of all, he controls the driving style, namely the speed. The next indicators are the conditions in which the car is moving. Here we mean the duration of the trip and when it takes place, at what time of day.
The braking system and the steering column switches belong to the control system, which is also controlled by the system. Finally, the acceleration is controlled, namely lateral and longitudinal.
Monitoring the current state, the system compares it with the original. If the indicators signal a significant deviation from the norm, a sound signal is turned on and the message "Attention Assist: Pause" is displayed on the screen panel, warning the driver to stop. The signal is notified every 15 minutes if the warning is ignored. The system is activated from a speed of 80 km / h. The analysis of speed, maneuverability and the removal of other parameters occurs 30 minutes after the start of the movement, since most often this is exactly how much time is required to move over long distances.
Driver Alert Control (DAC)
If an overwork condition is detected, the system alerts the driver with a signal and the message “Driver Alert. Time for a break ". The system starts to operate at a speed of 60 km / h.
Seeing Machines
The latest system that monitors the driver's condition is the Seeing Machine, implemented in the British brand Jaguar. It is noteworthy that this technology is used not only in the case of driving a car, but in other areas. The system is built exclusively on monitoring the external physical condition of the driver. The built-in camera records the position of the eyes and their direction.
If the indicator deviates from the norm, the system notifies of fatigue and the likelihood of falling asleep while driving with a signal and a special message.
The perfection of this technology is that it is activated even if the driver is wearing sunglasses. This system also includes additional parameters. For example, the system detects lack of attention to the rearview mirror. In this case, the driver receives a reminder of this action.
