Common fatigue monitoring system equipment is referred to as “driver fatigue warning system (BAWS)” which is an image based on the physiological reactions of the driver, the ECU and two camera modules, using the facial features of the driver, the eye signal, mobility header and the like to infer the fatigue state of the driver, and alarm means and take appropriate measures. Give active intelligence of security for the occupants.
1. Noun fatigue monitoring system
The Common fatigue monitoring equipment is referred to as “driver fatigue warning system (BAWS)” which is an image based on the physiological reactions of the driver, the camera ECU and of two modules, using the facial features of the driver’s fatigue, eye signal, the motion estimation of the driver’s head and the like, and alarm means and to take appropriate measures. Give active intelligence of security for the occupants.
2. Fatigue identification Introduction
Other automotive fatigue monitoring system equipment is referred to as “fatigue recognition system” (which will be the operating behavior of the driver from the driver at the start of recording) and through identifying changes in the driving operation of long-distance travel in the degree of fatigue of the driver is determined. 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.
3. Introduction to the attention assist system
Some carFatigue 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.
4. Driver Safety Warning System (the DAC)
There are also a part of the fatigue monitoring system is called “driver safety warning system” the system is easy to make the driver enters the vehicle into a relaxed state of straight, flat road, the driver easily distracted and environmental nap, and when the speed 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 assessment is the result of 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.
