Problems solved by technology

For example, the passenger seat occupant classification advanced airbag system is realized by the occupant occupancy detection system using the weight detection sensor, resulting in the airbag not working when the weight on the seat of the weight detection sensor is not accurately detected
The inoperability of the air bag is caused by an adult sitting in an incorrect sitting posture, a sensor failure due to non-recognition of the seat cover, or a malfunction or failure due to deterioration of the sensor or other reasons, and thus, there is Risk of Serious Injury to Passengers
[0009] Additionally, the rear seat occupant notification system can be implemented through an occupant occupancy detection system that utilizes ultrasonic sensors, thus potentially causing false alarms if the ultrasonic sensors used to detect movement within the vehicle to determine the presence of occupants fail
The rear seat occupant notification system also has the limitation that only the door open sensor is used to determine the presence of an occupant and whether the vehicle's rear doors are open / closed

Abstract

The invention provides a method of passenger detection using interconnecting sensors and a passenger occupancy detection system thereof. The passenger occupancy detection system is provided that implements a sensor-connected passenger detection method. The system includes a sensor controller that reads a sensor value using an ESC as an acceleration sensor when a vehicle is stopped and distinguishes an in-vehicle passenger with a vehicle acceleration change by the sensor value. The operations of a rear-seat passenger notification system 200 and a passenger-seat occupant classification advancedairbag system 300 are connected by the distinguishing the in-vehicle passenger, enhancing the sensor reliability by providing Fail-Safe together with increasing the accuracy of the passenger detectionutilizing longitudinal / lateral accelerations / yaw rate information.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2018-0052474 filed on May 8, 2018, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a method of passenger detection, and more particularly, to a method of passenger detection using a passenger occupancy detection system that enhances the reliability of sensors by implementing failsafes thereof. Background technique [0004] Recently, a passenger occupancy detection system applied to a vehicle enhances the operational reliability of a safety system mounted on a vehicle by accurately confirming the presence of a passenger using a sensor. Accordingly, the occupant occupancy detection system works in conjunction with passenger recognition of the advanced airbag system on the passenger seat using a weight detection sensor (or passenger classification sensor), or in conjunction with a rea...
