[0045] Example

[0046] reference image 3 In the present invention, each sensor array unit of the capacitor film layer includes sensor arrays of three densities, which are arrays of 9*9, 5*5, and 3*3 sensor unit densities per unit area. Place a 9*9 density sensor in the area A where the cushion touches more, and place a 3*3 density sensor on the edge area C. The remaining middle area B is arranged with 5*5 density sensors.

[0047] reference figure 1 , figure 2 Furthermore, the present invention also includes a protective jacket 8 for the smart cushion, and the jacket material is polyvinyl chloride. In application, the entire smart car seat cushion is placed in the PVC protective cover 8, and the power cord 17 is led out from the interface left in the protective cover to supply power to the flexible circuit. Fixed buckles 10, 11, 18, and 20 are arranged around the protective cover to fix the smart car cushion on the car seat.

Abstract

The present invention discloses an intelligent vehicle seat cushion and a measurement method thereof. The intelligent vehicle seat cushion comprises a seat cushion body and four alcohol concentration sensors attached to the seat cushion body. The seat cushion body comprises a piezoelectric film layer, a capacitor film layer, flexible insulation glue layers and a flexible circuit layer. The measurement method comprises the steps: collecting heart rate signals, breathing signals, pressure signals and alcohol concentration signals through the sensors; performing interference filtering on hardware and software; processing and calculating the collected signals to obtain a series of driving state information of a driver; and making a corresponding feedback early warning according to the obtained driving status. According to the intelligent vehicle seat cushion, the statuses of posture comfort, fatigue, and drinking or not of the driver during the driving process are measured through the non-contact circuit, and the measurement method is simple and suitable for real-time monitoring in the running process of the vehicle.

Description

technical field [0001] The invention relates to an automobile product, in particular to an intelligent automobile seat cushion and a measuring method thereof. Background technique [0002] In recent years, with the rapid development of my country's automobile manufacturing technology, more and more people have begun to drive cars or take buses as their own way of travel. As a fast and flexible means of transportation, automobiles have brought great convenience to the lives of our people and made great contributions to the economic development of our country. However, the widespread use of this means of transportation has also directly led to many A traffic accident happens. There are many reasons for car accidents, but a large part of the reasons for major car accidents that cause casualties is because drivers are drunk and fatigued during driving. [0003] Currently, the safe driving technologies on the market are all focused on the safety performance of the vehicle itsel...
