Embodiment 1

[0019] Such as figure 1 As shown, 3 in the figure is the vehicle controller, the input terminal of the vehicle controller 3 is connected with the output terminal of the EEG signal acquisition device 1 through the host computer 2, and the output terminal of the vehicle controller 3 is connected with the vehicle body controller in turn. 4. The air-conditioning controller 9 is connected to the input end of the motor controller 7; the output end of the body controller 4 is connected to the input end of the hazard alarm flashlight 5 and the voice reminder device 6 respectively; the output end of the air-conditioning controller 9 is connected to the input end of the electric air conditioner 10 The output terminal of the motor controller 7 is connected with the input terminal of the drive motor 8 .

[0020] When a person is in a fatigued state, the amplitude of the α wave in the EEG signal with a band of 8-13.8 Hz will change significantly. The present invention collects the driver's...

Embodiment 2

[0022] A new energy vehicle fatigue driving early warning and mitigation system adopted in this embodiment, combined with figure 1 ,Such as figure 2 shown, including the following steps:

[0023] In step 201, the vehicle starts to run, and the fatigue driving warning and mitigation system is activated;

[0024] In step 202, when the car is in a driving state, the EEG signal acquisition device collects the driver's EEG signal in real time and sends the EEG signal to the host computer;

[0025] In step 203, the host computer receives the EEG signal and performs real-time signal processing on it;

[0026] In step 204, the host computer judges whether the driver is in a fatigue driving state according to the amplitude change of the α wave in the collected EEG signal;

[0027] If the judgment result of the host computer is that the driver is not in the fatigue driving state (N), the system continues to execute step 202 to collect the driver's EEG signal in real time and send th...

Abstract

The invention discloses a fatigue driving early-warning and alleviating system for a new energy automobile. The fatigue driving early-warning and alleviating system comprises an automobile controller, wherein in the technical essential, an input end of the automobile controller is connected with an output end of an electroencephalogram signal acquisition device through an upper computer, and an output end of the automobile controller is sequentially connected with input ends of a body controller, an air conditioner controller and a motor controller; an output end of the body controller is connected with input ends of a danger alarming flash lamp and a voice prompting device respectively; an output end of the air conditioner controller is connected with an input end of an electric air conditioner; and an output end of the motor controller is connected with an input end of a drive motor. The fatigue driving early-warning and alleviating system disclosed by the invention has the function of warning other vehicles by automatically turning on the danger alarming flash lamp through the body controller once a driver is in a fatigue driving state; or, accidents due to a too high driving speed of the automobile are avoided by controlling the drive motor to reduce a rotational speed through the motor controller; or the purpose of alleviating the fatigue of the driver is achieved by turning on the electric air conditioner to lower a temperature in the automobile through the air conditioner controller, thus converting the fatigue driving state to a safe state.

Description

technical field [0001] The invention relates to the technical field related to new energy vehicles, in particular to a fatigue driving early warning and relief system for new energy vehicles. Background technique [0002] In recent years, in expressway driving, major traffic accidents caused by drivers' fatigue driving, drunkenness, and drowsiness have doubled. Therefore, countries all over the world are conducting a lot of research and development on vehicle-mounted drowsiness prevention devices. Therefore, the research on the real-time early warning and mitigation system of driver fatigue driving has gradually become a scientific research hotspot. Such as identifying brain waves, judging sleep posture, brain position deviation, hand grip changes, blink frequency judgment, etc. Because all there is the uncertainty of judging the drowsy state of the driver in the above-mentioned various methods and there is no emergency parking device, so still there is no driver's drowsine...
