Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
fig. 1 and fig. 2 show a specific embodiment of the fatigue driving reminding device of the present invention. Fig. 1 is a schematic structural view of a fatigue driving warning device in the present embodiment; fig. 2 is a schematic configuration diagram of the fatigue monitoring system according to the present embodiment.
As shown in fig. 1, the fatigue driving reminder according to the present embodiment includes a fatigue monitoring system 3 and a massage seat 5 for the driver, wherein the fatigue monitoring system 3 is connected to a controller of the massage seat 5 through a CAN network and a vehicle body control module BCM4, and the controller controls a massage motor of the massage seat 5 to output high-frequency low-torque fluctuations that cause discomfort to a person, thereby functioning to stimulate the driver to keep the driver awake.
Preferably, the fatigue monitoring system 3 includes a fatigue driving judgment module 31, and an in-vehicle camera 32, a steering wheel steering sensor 33 and a duration acquisition module 34 which are respectively connected with the fatigue driving judgment module 31; the in-vehicle camera 32 includes at least a face camera, as shown in fig. 2. The facial camera of the in-vehicle camera 32 is used to acquire facial expression characteristics of the driver, such as fatigue signs of yawning, dozing, and the like. The in-vehicle camera 32 may also include a camera that captures the driver's driving actions. The steering wheel steering sensor 33 is used to acquire information such as the frequency of steering operation, a slight but jerky steering action of the driver with steering, and the like.
Preferably, the fatigue monitoring system 3 further includes a duration collecting module 34, and the duration collecting module 34 is connected to the fatigue driving judging module 31. The duration acquisition module 34 is used for acquiring the driving duration of the driver, as shown in fig. 2.
Preferably, the fatigue driving reminding device in the present embodiment further includes an intelligent wearable device worn on the driver, and the intelligent wearable device monitors the body index of the driver and transmits the body index to the fatigue monitoring system 3 through the T-BOX 2.
