Passenger discriminating apparatus employing two load sensors
First Claim
1. A passenger discriminating apparatus, comprising:
- a plurality of load sensors that each measure a load value of a passenger seated in a passenger seat disposed within a vehicle; and
a pair of dummy sensors configured to support a load of the passenger seat, the dummy sensors not performing a load sensing function,wherein the passenger discriminating apparatus discriminates a type of the passenger by multiplying each of the load values by a load weight, summing the products of the load values and the load weights, and comparing the sum to a reference value, andthe load weights are determined so that a difference between a minimum adult test measurement weight value, which is a minimum value of adult test measurement load values measured when an adult dummy is seated in the passenger seat in a specific condition, and a maximum infant test measurement weight value, which is a maximum value of infant test measurement load values measured when an infant dummy is seated in the passenger seat in the specific condition, is maximized.

Abstract
A passenger discriminating apparatus according to the present invention includes a plurality of load sensors for measuring a load of a passenger, which is applied to a passenger seat disposed within a vehicle, and a pair of dummy sensors configured to support the load of the passenger seat and not having a load sensing function. The type of the passenger is discriminated by comparing a sum of values in which the load values measured by the plurality of load sensors, respectively, are multiplied by a load weight of the load sensors and a reference value. Accordingly, the passenger discriminating apparatus can save the prime cost, reduce its weight, and secure an equivalent or more performance.

-
a plurality of load sensors that each measure a load value of a passenger seated in a passenger seat disposed within a vehicle; and a pair of dummy sensors configured to support a load of the passenger seat, the dummy sensors not performing a load sensing function, wherein the passenger discriminating apparatus discriminates a type of the passenger by multiplying each of the load values by a load weight, summing the products of the load values and the load weights, and comparing the sum to a reference value, and the reference value is an average of a minimum value of an adult test measurement value that is already measured, and a maximum value of an infant test measurement value that is already measured.
