Problems solved by technology
[0002]Existing fatigue driving detection technologies are almost all based on cameras, which identify the driver's fatigue state by collecting yawning or nodding movements of the face. An additional infrared camera and image processor are required for the device, which will only increase the cost of the device and cannot be quickly ported to devices without cameras
[0003] In the use of sensors to identify the driver's driving behavior, it mainly uses the six-axis sensor data in the device to calculate the steering angular velocity in the horizontal direction of the vehicle, and then calculates the zero velocity of the angular velocity The percentage and the standard deviation of the angular velocity are used as the basis for judging fatigue driving. These two solutions are also used in most patents and papers today. However, in the actual vehicle test, the calculation based on the zero speed percentage and standard deviation has a high false alarm rate. Especially when the vehicle makes a large lane change, the false alarm rate is high

The invention relates to the technical field of fatigue driving. The invention provides a vehicle fatigue driving accurate judgment method, terminal equipment and a storage medium. In this method, inthe vehicle driving process, when the fatigue driving is preliminarily judged, further judgment is carried out by using the following method: and according to a time-steering angular velocity curve drawn according to the vehicle driving data, an area defined by the curve and a straight line where the time axis, the steering angular velocity upper limit threshold value and the steering angular velocity lower limit threshold value are located in a sampling time period is set as a selected area, it is calculated whether the selected area is smaller than an area threshold value or not, and if yes,fatigue driving is determined. According to the invention, whether a driver is in abnormal driving in a fatigue state or rapid lane changing overtaking in a normal state can be distinguished in the vehicle driving process, the false alarm rate of a program is reduced, and the accuracy is improved.

technical field [0001] The invention relates to the technical field of fatigue driving, in particular to a method for accurately judging vehicle fatigue driving, a terminal device and a storage medium. Background technique [0002] Existing fatigue driving detection technologies are almost all based on the camera, which recognizes the driver’s fatigue state by collecting yawning or nodding movements on the face. It increases the cost of the device and cannot be quickly ported to a device without a camera.
