Improved passenger sensing system

Abstract

The invention relates to an improved passenger sensing system which comprises passenger seats and a sensor part, wherein the passenger seats are arranged on a vehicle; and the sensor part senses a plurality of load values according to passenger positions on the passenger seats; the passenger weight is calculated out on the basis of the load value and then compared with a first setting value, and an air bag is expanded with high pressure when the passenger weight is more than the first setting value; a difference value is calculated out by mutually comparing the load values when the passenger weight is less than the first setting value, the difference value is compared with a second setting value, and the air bag is expanded with low pressure when the difference value is less than the second setting value; and whether a passenger sits at the front part of the passenger seat or not is judged when the difference value is more than or equal to the second setting value, the air bag is expanded with low pressure if the passenger sits at the front part of the passenger seat, and a control part of the air bag is expanded with high pressure if the passenger does not sit at the front part of the passenger seat. The improved passenger sensing system ensures that an adult can not be considered as a child passenger by mistake when sitting on the passenger seat in an abnormal posture, and can identify the passengers correctly and effectively protect the passengers on the seats.

Description

technical field [0001] The present invention relates to an improved passenger sensing system, specifically, an improved passenger sensing system that effectively protects passengers by correctly identifying them as adults instead of being mistaken for a child passenger when an adult sits in a passenger seat in an abnormal posture . Background technique [0002] Generally speaking, the airbag is a device that uses the elasticity of the air cushion to absorb the physical impact that occurs when the vehicle hits, and protects the passengers in the vehicle. It is divided into driver's seat airbag, passenger airbag, side airbag and safety air curtain. [0003] On the one hand, in terms of the deployment speed of the air cushion after the gas flows into the above-mentioned air cushion when the vehicle hits, in order to protect the passengers, the airbag is deployed at a high speed, so when the passenger sitting on the passenger seat is a child, the impact caused by the deployment ...

Problems solved by technology

[0005] However, the air bag control device related to the conventional technology is when the passenger is not normally sitting on the passenger seat, that is, not sitting in a position conforming to the design intention, but leaning in one direction of the passenger seat or maintaining an incorrect posture, although the above-mentioned passenger is Adults, but when the weight of the passengers sensed by two or more sensors is small, the adult is mistaken for a child, and the airbag fails to deploy the airbag at a pressure that effectively protects the adult, but deploys the airbag at a low pressure
