AIRBAG CONTROL SYSTEM WHICH CONSTANTLY PROVIDES POWER TO A STPS CAPABLE OF FIGURING OUT THE LOCATION OF A SEAT USING A STPS

摘要

PURPOSE: An airbag control system which constantly provides power to a Seat Track Position Sensor is provided to steadily figure out a state of a sensor by repeated signals.;CONSTITUTION: An airbag control system which constantly provides power to a STPS comprises a power unit(54), a STPS unit(50), and an Airbag Control Unit(500). The STPS unit figures out the location of a seat by current change. The current change is generated when the seat is moved in a Hall Integrated Circuit(22). The ACU controls an airbag according to an airbag inflation logic. And the ACU continuously supplies power to the STPS unit by applying an interface Application Specific Integrated Circuit(520).;COPYRIGHT KIPO 2010
