PROBLEM TO BE SOLVED: To provide a method capable of effectively reducing power consumption used for BLE beacon without requiring complicated calculation or useless power consumption in a unit such as a smart key system which uses BLE beacon.SOLUTION: A car navigation system is capable of determining the wave strength of an output radio depending on the state of a vehicle. A BLE beacon 101 is driven with a strength of radio wave instructed by the car navigation system to properly control the same to thereby reduce the power consumption.SELECTED DRAWING: Figure 1
【課題】BLEビーコンを用いたスマートキーシステムのような対象において、複雑な演算または余計な電力消費を必要とせず、BLEビーコンによる消費電力の低下を効果的に実現する方法を提供することを目的とする。【解決手段】カーナビゲーションシステムは車両状態に応じた出力電波強度を決定する事ができる。またBLEビーコン101は、カーナビゲーションシステムから指示された電波強度で駆動することで電波強度を適切に制御する事ができ、消費電力を低減することができる。【選択図】図1
