The occupant detection sensor is referred to as the occupant classifier (OC-3 mat) that is located in the seat area of the passenger seat and is made of conductors equipped with pressure-dependent resistor elements connected to an analyser. Such elements are designed to permit individual selection wherein an application of mechanical load to the SEN element reduces the electrical load and vice versa. The occupancy and local weight concentrations of the seat surface are determined by laying the signals captured from the various parts of the mat on a map. For the most part, the OC-3 mat is tasked with sensing the location of a person or object on the front passenger seat and deciding whether or not the passenger side airbags need to be disabled. Based on the weight pattern, it can detect a child seat that conforms to the NHTSA FMVSS 208 standard and causes the disabling of the passenger airbags if such a seat is detected. Further, the mat is able to distinguish between the child - one-year-old in the child seat and the light person by calculating the distances between the pressure, applying areas and pressure concentrations. Through K-CAN, OC-3 mat analyzer sends signals to MRS control module to turn off the front passenger side airbags if the detected seat is empty or if a child seat for a child aged up to one year is installed, with the status lamp informing the occupants that the airbags have been disabled.
