Embodiment 1

[0059] according to figure 1 , figure 2 and image 3 , the present invention includes a seat safety device 1 , a sensor 2 and an occupancy recognition control module 3 .

[0060] Such as figure 2 As shown, several sensors 2 are arranged inside the seat cushion portion 10, which are evenly distributed in the passenger seat cushion, and are detected at intervals of a set time, which may be 1.5 seconds to 5 seconds. In the example, a detection is performed every 2.5 seconds. When someone is sitting on the seat, the pressure on the surface of the seat will increase, and the metal diaphragm of the sensor 2 will be deformed due to the pressure, so that the resistance of the metal diaphragm in the sensor 2 will The value changes accordingly, and the pressure signal is collected by the sensor 2 and sent to the occupancy recognition control module 3 .

[0061] Such as figure 1 As shown, the occupancy recognition control module 3 calculates the corresponding pressure value accord...

Embodiment 2

[0070] according to Figure 4 and Figure 5 , the difference between this embodiment and embodiment 1 is: in this embodiment, if Figure 4 As shown, the system also includes a memory 4, the memory 4 stores the records of the seats, the records include the occupied state information and the current time, the memory 4 accepts the call, read and write operations performed by the occupancy identification control module 3, In this embodiment, this memory 4 can be a temporary storage space. For example, because the space required by the memory 4 is small, a temporary space can be defined in the system memory for keeping the records of the seat. The operating speed of the system can be guaranteed; the occupancy recognition control module 3 also calculates the relevant time value in the record, and controls the seat safety equipment accordingly.

[0071] Such as Figure 5 As shown, the specific control flow of this embodiment is as follows:

[0072] 1. Sensor 2 collects pressure s...

Embodiment 3

[0086] according to Figure 6 and Figure 7 , the difference between this embodiment and embodiment 2 is: in this embodiment, if Figure 6 As shown, the system also includes a child seat 5, a radar transceiver 50 is arranged in the child seat 5, a wireless signal transceiver processing module 6 corresponding to the radar transceiver 50 is provided in the system, and the occupancy recognition control module 3 directs the wireless The signal transceiving processing module 6 issues a child seat detection command; the wireless signal transceiving processing module 6 communicates with the radar transceiver 50 according to the detection command to reflect the state information of the child seat 5 occupying the seat; the seat safety device 1 includes a seat Seat front airbag 11, seat side airbag 12 and seat belt early warning device 13.

[0087] Such as Figure 6 As shown, the wireless signal sending and receiving processing module 6 sends the received response signal of the child...

Abstract

This invention relates to a process method for safety equipments of seats of cars and a system including: A, getting the pressure signal of a sensor, B, operating relatively according to the pressure value expressed by the pressure signal and its set threshold value, B1, if the pressure value is greater than or equal to the threshold value, it is determined that the seat is occupied to start up the safety device, B2, if the value is smaller than the threshold value, it is determined that it is not occupied and the safety device is closed, the system includes a seat safety device, a sensor and an identifying module, in which, the sensor collects pressure signal of the seat and transfers it to the identifying control module, which computes related pressure value according to the signal and emits related control signal to the safety device of the seat according to the pressure value and the threshold value.

Description

technical field [0001] The invention relates to automobiles, in particular to a method and system for processing seat safety equipment. Background technique [0002] With the rapid development of the automobile industry and the development and construction of highways, the speed of automobiles is getting faster and faster, and traffic accidents are more frequent, so the safety of automobiles has become particularly important. [0003] Various seat safety devices have emerged, such as Supplemental Restraint System (SRS: Supplemental Restraint System), referred to as airbag, which is a high-tech product in automotive passive safety technology, and seat belt early warning devices, etc. . This seat safety device has played a very important role in reducing the loss of automobile collision accidents. [0004] Yet this seat safety device is a disposable product, and after the explosion, the seat front air bag, the seat side air bag and the seat belt early warning device must be ...
