1. A method for classifying passengers, comprising the steps of:
- providing a plurality of load sensors disposed in a passenger seat of an automobile for measuring a load applied to the passenger seat;
obtaining a sum by summing respective values obtained by multiplying respective load values measured from the plurality of load sensors by weighted load values of the respective load sensors;
comparing the sum with a reference value to classify a passenger on the passenger seat;
wherein the plurality of load sensors consists of three load sensors and the weighted load values of the three respective load sensors are determined so as to satisfy all of [Equation 1], [Equation 2], and [Equation 3] under the condition that [Equation 4] is satisfied;
Ai=X1i*S1i+X2i+*S2i+X3i*S3i
[Equation 1]wherein Ai is an adult test measurement weight value measured in advance under a predetermined condition (i), Xki is a weighted load value of a k-th load sensor under the predetermined condition (i), and Ski is a load value measured by the k-th load sensor when an adult dummy is seated on the passenger seat,
Ci=X1i*S1i+X2i*S2i+X3i*S3i
[Equation 2]wherein Ci is an infant test measurement weight value measured in advance under a predetermined condition (i), Xki is a weighted load value of a k-th load sensor under the predetermined condition (i), and Ski is a load value measured by the k-th load sensor when an infant dummy is seated on the passenger seat,
X1i+X2i+X3i=T
[Equation 3]wherein Xki is a weighted load value of a k-th weight load sensor under the predetermined condition (i) and T is a specific limit value,
MAX[MIN(Ai)−
MAX (Ci)]
[Equation 4]wherein Ai is an adult test measurement weight value measured in advance under a predetermined condition (i), and Ci is an infant test measurement weight value measured in advance under the predetermined condition (i).
