Embodiment

[0047] The fatigue driving detection system of the embodiment of the present invention is composed of a heart rate detection unit, a breathing detection unit, a driving habit data acquisition unit, an analysis and calculation unit, and a display and reminder unit. For a schematic diagram of its structure, see figure 1 , wherein, the heart rate detection unit, the respiration detection unit, the driving habit data acquisition unit and the display reminder unit are all connected to the analysis and calculation unit. The heart rate detection unit is used to collect the driver's heart rate data after the driver puts on the seat belt and transmit it to the analysis and calculation unit; the breath detection unit is used to collect the driver's respiratory rate data and transmit it to the analysis and calculation unit; driving habits The data acquisition unit is used to connect to the car bus, read the driving conditions of the vehicle and the driver’s driving conditions, and transmi...

Abstract

The invention provides a fatigue driving detection system and method, and belongs to the field of vehicle intelligent terminals. The invention solves the problem that fatigue driving objective detection methods in the prior art adopt a direct or an indirect way for detection, and cannot effectively detect the actual fatigue condition of the driver in combination with the actual situation. The keypoints of the technical scheme are that: the fatigue driving detection system comprises a heart rate detecting unit, a breathing detecting unit, a driving habit data collecting unit, an analysis calculating unit and a display reminding unit, the heart rate detecting unit, the breathing detecting unit, the driving habit data collecting unit and the display reminding unit are all connected to the analysis calculating unit. The fatigue driving detection method is applied to the fatigue driving detection system, analyzes whether the driver is fatigued or not by collecting data such as changes in the heart rate, changes in breathing conditions and changes in driving habits of the driver, and performs reminding display according to the fatigue condition of the driver.

Description

technical field [0001] The invention relates to vehicle-mounted intelligent terminal technology, in particular to the technology of fatigue driving detection. Background technique [0002] Fatigue driving detection has always been an important requirement in the field of automotive intelligent applications. At present, there are various methods for fatigue driving detection. The more common methods are objective evaluation method and subjective evaluation method. The subjective evaluation method mainly uses the driving recorder data or Fill in the form of questionnaires, and evaluate the physiological state during driving after driving; the objective evaluation method is compared with the subjective evaluation method, mainly through the intervention of detection equipment to collect relevant parameters of driver fatigue for fatigue judgment. [0003] Objective assessment methods are further divided into direct and indirect methods: the direct method mainly detects changes in...
