METHOD AND SYSTEM FOR COMMUNICATING BETWEEN SENSORS AND A SUPPLEMENTAL RESTRAINT SYSTEM CONTROLLER

摘要

A system and method for communicating between a single electronic controller and multiple sensor devices in a vehicle supplemental restraint system includes a unique communication protocol. A series of pulses, each having a chosen duration, are communicated between the sensor device and the controller. The combined sequence and duration of each pulse provides a unique piece of information to the controller regarding the condition sensed by each sensor device, respectively. By controlling the sequence and duration of pulses, each sensor device is able to provide unique information to the controller, which responsively controls the supplemental restraint device as needed.
