How does the Vehicle Surveillance Cameras DMS/ADAS detect fatigue driving?

Generally, the simple way for a car to detect fatigue driving is to calculate the continuous driving time, and an alarm will be issued once the time preset by the system is exceeded. There are also some cars with driver fatigue detection functions that will be judged by the rotation of the steering wheel or other driving behaviors of the driver.

Commonly equipped fatigue monitoring system is called "Fatigue Driving Early Warning System (DMS). It is based on the driver`s physiological image response and consists of two modules, ECU and camera, which utilizes the driver`s facial features, eye signals, and head movement. It is a device that infers the driver`s fatigue state, and gives warning and prompts and takes corresponding measures. Provide active and intelligent safety guarantee for drivers and Vehicle security system.

Other fatigue monitoring systems equipped with cars are called "fatigue recognition systems" (it records the driver`s operating behavior from the beginning of driving) and can monitor the driver`s fatigue by recognizing changes in driving operations during long-distance trips. judge. The driver's steering operation frequency becomes low, and accompanied by slight but sudden steering actions to maintain the driving direction is a typical manifestation of lack of driving energy.

Smart Security Device system Based on the frequency of the above actions, combined with other parameters such as journey length, turn signal usage, driving time and other parameters, the system calculates and discriminates the driver`s fatigue level. If the calculation result exceeds a certain value, the dashboard will flash The pattern of a coffee cup reminds the driver to take a break.

The driver fatigue recognition system takes the driver's concentration of attention as an important consideration factor to measure the driver's driving state, and is committed to improving Various Vehicle Monitoring Systems safety.
