To prevent a second control device from being brought into a wake-up state when an ignition switch is in an OFF-state, so that consumption currents do not increase, when the second control device also utilizes detected data by an acceleration detecting part provided in a first control device.SOLUTION: Pieces of detected acceleration data detected by an acceleration sensor 21 of an ECU 2 for controlling an airbag just after a vehicle stops while an ignition switch is in an OFF-state are memorized in a memory 23, and pieces of detected acceleration data detected just before the ignition switch is turned off memorized in the memory 23 are transmitted from a transmission part 24 of the ECU 2 for controlling an airbag just after the ignition switch is turned on, and the pieces of data are received by a reception part 31 of an ECU 3 for controlling an optical axis to derive a vehicle attitude angle θv, so as to control an inclination angle of an optical axis of a head lamp.SELECTED DRAWING: Figure 1 【課題】第１の制御装置に設けられた加速度検出部の検出データを第２の制御装置でも利用するときに、イグニッションスイッチのオフ時に第２の制御装置がウェイクアップ状態になって消費電流が増加するのを防止できるようにする。【解決手段】イグニッションスイッチのオフ中を含む車両が停車した直後のエアバッグ制御用ＥＣＵ２の加速度センサ２１による加速度検出データをメモリ２３に記憶しておき、イグニッションスイッチのオン直後にエアバッグ制御用ＥＣＵ２の送信部２４からメモリ２３に記憶されたイグニッションスイッチのオフ直前の加速度検出データを送信し、このデータを光軸制御用ＥＣＵ３の受信部３１により受信して車両姿勢角θｖを導出し、ヘッドランプの光軸の傾き角度を制御する。【選択図】図１
