Embodiment Construction

[0015] refer to figure 2 : In step S00, the existing seat body pressure distribution measurement system (the system has a set of body pressure distribution cushion type sensors for measuring the pressure distribution of human buttocks on the seat) is arranged on the seat.

[0016] In step S11, the pressure distribution data is directly read from the seat pressure distribution testing system. Establish the original distribution database of occupant body pressure under different types and different sitting positions.

[0017] Said pressure-sensitive area is obtained by the method of sample variance of series points, and the specific steps are:

[0018] In step S21, the pressure distribution sensitive area is analyzed.

[0019] Let (X 1 , X 2 ,...,X n ) is a series of pressure values ​​collected at each collection point, the statistics

[0020] S 2 = 1 n - 1 ...

Abstract

The invention relates to an identifying method for the physical signs of vehicle passengers, which includes the following steps: a) the step of obtaining a pressure sensitive point: obtaining the physical sign data of the passengers with different passenger types and different sitting positions by a vehicle carrier pressure distribution measuring system, finding out a pressure sensitive area by analyzing and arranging a pressure measuring sensor array; b) the step of obtaining and processing pressure values used for identifying: arranging the pressure values under different passenger types and different sitting positions by a measuring system vehicle sensor; c) the step of identifying the physical signs of vehicle passengers: building the characteristic database with different typical physical signs according to the specific regulation requirements, obtaining a classifier model, inputting body pressure distribution data into a trained classifier to carry out sorting and finally transmitting the obtained physical sign information of the passengers into an intelligent safe air bag controller for the use of intelligent control of the controller. The identifying method provides a method for effectively identifying the physical signs of the vehicle passengers, can reduce the secondary damage on the air bag to the lowest point when the vehicle is impacted and can improve the passive safety performance of the vehicle.

Description

technical field [0001] The invention relates to safety measures for vehicle operation, in particular to a method for identifying signs of vehicle occupants. Background technique [0002] The main purpose of the research and development of the airbag system is to avoid the secondary collision between the human body and the interior parts of the vehicle body during the collision process, and reduce the damage to the human body. In recent years, the widespread use of car seat belts and car airbags has greatly reduced the casualty rate in traffic accidents. But, because conventional safety airbag system is the airbag of occupant design according to the fiftieth percentile normal position, for this reason, conventional safety airbag is very likely to cause injury to off-position occupant and small stature women and even children. [0003] In order to effectively reduce the possibility of different types of occupant injuries caused by airbag deployment, different types of intelli...
