Embodiment Construction

[0019] figure 1 The multiplexing manner of the loop connections in the embodiment of the passenger seat sensor 30 is schematically shown. The passenger seat sensor 30 is composed of one or more than one sensing loop 10, and the sensing loop 10 is composed of several sensing points 11, 12 and the like. Such as the sensing points 11 , 12 , etc., will undergo corresponding impedance changes under the action of the external pressure, and output the output in the form of resistance changes through the sensing circuit 10 .

[0020] exist figure 1 The feature of the loop multiplexing composite connection of the sensing loop 10 is schematically shown in . The external port 01 of the sensing circuit 10 is composed of a first connecting line terminal 02 and a second connecting line terminal 03, and the inside of the circuit passes through several relatively independent sensing points 11, 12, and the first main connecting line 04, the second main connecting line The connection line 0...

Abstract

An occupant seat recognition sensor, which is composed of more than one sensing loop, the sensing loop is composed of several sensing points connected in parallel, and the two ends of each sensing point are connected with two main connecting lines, characterized in that the The main connecting lines of the sensing circuits are all provided with multiplexed connecting circuits connected in parallel with the main connecting lines. Through the technical improvement of the present invention, it is possible to effectively reduce the occurrence of high frequency of such sensor faults on vehicles currently produced, improve the stability of the system, further reduce the incidence of such faults in vehicles, and strengthen the occupant safety protection of road vehicles sex.

Description

technical field [0001] The invention relates to a pressure-type conductive thin film sensing and detecting system, which is mainly used in the field of identification and sensing of passenger seats of road vehicles. Background technique [0002] With the development of modern road vehicle technology, more and more occupant safety protection technologies are used in the field of vehicle safety. Subsequently, the occupant sensor technology of road vehicles has also been continuously developed, especially in the fields of vehicle airbag control and seat belt locking. [0003] This type of occupant occupancy recognition and sensor judges and determines the safety signal output related to the position of the seat through the occupancy of the occupant seat on the vehicle, and then determines such as the output of the alarm signal, the status of the preset airbag detonation, etc. [0004] One known type of technology for such occupant occupant recognition and sensors is human pres...
