Patent ID: 7606647

Claim:
A communication control device for passenger protection device, comprising: a satellite sensor unit which is installed at a predetermined position on a vehicle and comprises a satellite sensor main body, which detects an impact against the vehicle to provide an impact signal, and a controller, which provides a measured impact data signal in response to the impact signal; and an ECU which is installed at a predetermined position on the vehicle and comprises a main controller which determines deployment of a passenger protection device, the ECU being connected to the satellite sensor unit via a communication line, wherein the controller is constructed and arranged to compare a comparing impact value related to the measured impact data signal with a preset reference impact value range, when the comparing impact value is in excess of the preset reference impact value range, the controller transmits an output signal from the satellite sensor unit to the ECU at a first time interval, and, when the comparing impact value is within the reference impact value range, the controller transmits the output signal at a second time interval which is longer than the first time interval.
