Embodiment 1

[0058] According to FIG. 1 , FIG. 2 and FIG. 3 , the present invention includes a seat safety device 1 , a sensor 2 and an occupancy recognition control module 3 .

[0059] As shown in Figure 2, several sensors 2 are arranged inside the seat cushion portion 10, which are evenly distributed in the passenger seat cushion, and are detected at every set time interval, which can be 1.5 seconds-5 seconds, In this embodiment, 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 metal film in the sensor 2 will The resistance value of the sheet changes accordingly, and the sensor 2 collects the pressure signal and sends it to the occupancy recognition control module 3 .

[0060] As shown in Figure 1, the occupancy recognition control module 3 calculates the corresponding pressure value according to the received pressu...

Embodiment 2

[0069] According to Fig. 4 and Fig. 5, the difference between this embodiment and embodiment 1 is: in this embodiment, as shown in Fig. 4, the system also includes a memory 4, and the memory 4 stores records of seats, including Occupied state information and the time at that time, the memory 4 accepts calls, read and write operations performed by the occupation identification control module 3, in this embodiment, this memory 4 can be a temporary storage space, for example, because the memory 4 Required space is less, can delineate a temporary space in system internal memory and be used for keeping the record of seat, simultaneously, can guarantee the running speed of system again; Occupy recognition control module 3 also calculates relevant time value in the record, to The seat safety equipment is controlled accordingly.

[0070] As shown in Figure 5, the specific control process of this embodiment is as follows:

[0071] 1. Sensor 2 collects pressure signals.

[0072] 2. Th...

Embodiment 3

[0085] According to Fig. 6 and Fig. 7, the difference between this embodiment and embodiment 2 is: in this embodiment, as shown in Fig. 6, the system also includes a child seat 5, and a radar transceiver 50 is arranged in the child seat 5 , the system is also provided with a wireless signal transceiver processing module 6 corresponding to the radar transceiver 50, and the occupancy recognition control module 3 issues a child seat detection command to the wireless signal transceiver processing module 6; the wireless signal transceiver processing module 6 according to the detection command and the radar The information exchange between the transceivers 50 reflects the status information of the seat occupied by the child seat 5;

[0086] As shown in Figure 6, the wireless signal transceiving processing module 6 sends the received response signal of the child seat 5 to the occupancy identification control module 3, and the occupancy identification control module 3 responds to the s...

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 ...
