Communication control device for passenger protection device

A communication control device for passenger protection device includes a satellite sensor unit (10) and an ECU (20) being connected to the satellite sensor unit (10) via a communication line. The satellite sensor unit (10) includes a satellite sensor main body (31), which detects an impact against a vehicle (1), and a controller (32), which obtains a measurement from a signal detected by the satellite sensor main body (31). The ECU (20) includes a main controller (21) which determines deployment of a passenger protection device (60). The controller (32) of the satellite sensor unit (10) is adapted to compares the measurement or a calculated value which is calculated based on the measurement with a preset reference value range, and, when the measurement or the calculated value is within the reference value range, the controller (32) transmits a communication from the satellite sensor unit (10) to the ECU (20) at an interval which is longer than a predetermined time interval.
