using the driver’s facial features, eye signal, mobility header and the like to infer the fatigue state of the driver, and the alarm and take appropriate measures.

Fatigue recognition system
Other automotive equipment fatigue monitoring system is referred to as “fatigue identification system” (which will be the operating behavior of the driver from the driving start recording), and is capable of determining the degree of fatigue of the driver is identified by a change in the operation of driving long journey. Driver’s steering operation frequency is lowered, accompanied by a slight but abrupt steering operation to keep typical manifestation of the direction of travel is driving energy is not focused. The frequency of occurrence of the above operation, the length of the journey and such synthesis, the use of turn signals, driving time and other parameters, the system calculates the degree of fatigue of the driver and the discrimination, if the calculation result exceeds a certain value, flashes on the instrument panel a coffee cup pattern, suggesting that the driver needs a break. Driver fatigue recognition system will focus on the extent of the driver’s attention as an important consideration to measure the driver’s driving state, in an effort to improve road safety. Further, as long as the open fatigue recognition system, regardless of whether the system monitor, the system will alert the driver needs to 4 hours rest intervals.
attention assist system
There are some cars fatigue monitoring system equipment is called “Attention Assist” This system will continue to detect the traffic pattern of the driver. Sensor 71 detects the longitudinal and lateral acceleration of the steering wheel and pedal sensor system may be perceived to prompt the driver is fatigued after the appropriate rest driving the vehicle speed range between 80-180km / h on the vehicle.
Driver Safety Warning System (DAC)
There are also a part of the fatigue monitoring system is referred to as the “driver Safety Warning System” vehicle enters the system in the driver into a relaxed state easily straight, flat road, and easily distracted driver environment nap , and when the vehicle speed is over 65 km / h, will be activated. Driver safety warning system consists of a camera, a number of sensors and control units. The camera is mounted between the interior rearview mirror and the windshield, constantly measuring the distance between the vehicle and the lane marker, the signal emitted by the digital camera and the monitoring data from the vehicle steering wheel movement of the route traveled. The DAC can be abnormal driving conditions and your driving style compared to normal sensor records the car’s motion control unit stores the information and calculates whether there is danger of losing control of the car. If your driving behavior is detected signs of fatigue or distraction appears result of the assessment is a high risk that alerts the driver via sound signal. In addition, on the dashboard also displays a text message with a coffee cup symbol to alert drivers to rest.
