Problems solved by technology

[0003] The existing eye-tracking anti-fatigue technology usually directly controls the car to turn off the engine after multiple reminders or the reminder is invalid after detecting the driver’s fatigue driving. However, the direct turn off of the vehicle in motion has a greater impact on the car behind, which is likely to cause safety accidents

Embodiment Construction

[0013] see figure 1 , a safety belt with a fatigue driving reminder function, which includes a safety belt body; a heart rate sensor, arranged on the safety belt body, for detecting the driver's heart rate and outputting a heart rate signal; a processor, which communicates with the heart rate The sensor signal connection is used to receive and process the heart rate signal to judge the driver's fatigue level; the alarm device is connected to the processor signal and is used to generate a prompt signal when the driver is driving in fatigue.

[0014] Preferably, the safety belt body is provided with a vehicle speed detection device and an irritant gas sprayer, and the vehicle speed detection module and the irritant gas sprayer are respectively connected to the processor for signals.

[0015] When the vehicle speed detection module detects that the driving speed of the car is greater than 0, and the processor judges that the driver is in a state of fatigue, the processor sends an...

Abstract

The invention discloses a safety belt with a fatigue driving prompt function. The safety belt comprises a safety belt body, a heart rate sensor which is arranged on the safety belt body, directly faces the heart of the driver and is used for detecting the heart rate of the driver and outputting a heart rate signal; a processor which is in signal connection with the heart rate sensor and used for receiving and processing the heart rate signal to judge the fatigue degree of the driver; and an alarm device which is in signal connection with the processor and is used for generating a prompt signalwhen the driver is in fatigue driving. The safety belt can detect whether a driver is in a fatigue state or not in real time, and suggest the driver to stop for rest when judging that the driver is in the fatigue state.

Description

technical field [0001] The invention relates to the technical field of a driving assistance system, in particular to a safety belt with a fatigue driving reminder function. 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. There are many factors that cause fatigue driving. The driver's fatigue is mainly the fatigue of nerves and sensory organs, as well as limb fatigue caused by maintaining a fixed posture for a long time and poor blood circulation. The driver sits in a fixed seat for a long time, his movements are restricted, his at...
