Problems solved by technology
Under normal circumstances, drivers who drive more than 10 hours a day, or sleep less than 4-5 hours the day before, have a high accident rate.
[0012] This method mainly relies on the heartbeat sensor to collect the characteristic data of the driver's heartbeat to determine whether the driver is in a state of fatigue. Since each person's heartbeat speed is different, this method has a large error
In addition, this method only reminds the car owner without further active control. When the driver is tired and does not pay attention to the warning situation, traffic accidents are still easy to occur

Embodiment Construction
[0036] The technical scheme of the present invention is described in further detail below:
[0037] A car control method for preventing fatigue driving, comprising the following steps:
[0038] Step 1), installing a camera module and a rotation module in the car, the camera module is installed on the rotation module for capturing the driver's face image, and the rotation module is used for adjusting the shooting angle of the camera module;
[0039] Step 2), install the warning module in the car;
[0040] Step 3), when the vehicle starts, start the camera module and the rotation module;
[0041] Step 4), control the rotation module to adjust the shooting angle of the camera module, so that the camera module can capture the driver's face image from the front as much as possible;
[0042] Step 5), filtering and denoising the captured image;
[0043] Step 6), calculate the ratio of the area of the driver's pupil covered by the eyelid to the pupil area in the image;

The invention discloses an automobile control method for preventing fatigue driving. The method comprises the following steps: arranging a camera module, a rotating module and a warning module in an automobile; starting the camera module and the rotating module during starting the automobile; controlling the rotating module to adjust the shooting angle of the camera module so as to enable the camera module to shot the picture of the face of a driver from the front to the maximum; determining whether the driver is in a fatigue state according to the ratio of the area covered by eyelids, of the pupils of the driver in the picture to the pupil area; controlling the warning module to send warning information when the duration of the driver in the fatigue state is beyond the preset warning time threshold; controlling a braking module to brake and turn on a fault warming lamp of the automobile when the duration of the driver in the fatigue state is beyond the preset braking time threshold. With the adoption of the method, whether the driver is in the fatigue state can be determined, the driver can be reminded, the automobile can be actively braked in case of failure of reminding, and therefore, the traffic accident can be greatly avoided.
Description
technical field [0001] The invention relates to the field of automobile control, in particular to an automobile control method for preventing fatigue driving. Background technique [0002] Driving fatigue refers to the phenomenon that the driver's physiological function and psychological function are out of balance after driving continuously for a long time, and the driving skill declines objectively. The driver's sleep quality is poor or insufficient, and he is prone to fatigue after driving for a long time. Driving fatigue can affect various aspects such as driver's attention, feeling, consciousness, thinking, judgment, will, decision and motion. [0003] If you continue to drive the vehicle after fatigue, you will feel drowsy, drowsy, weak in limbs, inattention, decreased judgment ability, and even appear in a trance or instant memory loss, delayed or premature action, operation pause or improper correction time and other unsafe factors, Highly prone to road traffic acc...
