To provide a technique that ensures convenience even when communication in a smart entry system is stopped.SOLUTION: A portable machine 10 transmits, to an in-vehicle device 20, a second signal including information about the reception intensity of a first signal as a response to the first signal received from the in-vehicle device 20. An operation unit 100 receives an operation to stop communication with the in-vehicle device 20 from a user. When the operation unit 100 receives an operation, a communication unit 120 transmits, to the in-vehicle device 20, the second signal including information about a communication stop in accordance with the operation received by the operation unit 100. A control unit 102 causes the communication unit 120 to stop communicating with the in-vehicle device 20 in a case where the reception intensity of the first signal received in the communication unit 120 is equal to or less than a threshold.SELECTED DRAWING: Figure 2

    【課題】スマートエントリーシステムにおける通信を停止させる場合であっても利便性を確保する技術を提供する。【解決手段】携帯機10は、車載器20から受信した第1信号に対する応答として、第1信号の受信強度に関する情報が含まれた第2信号を車載器20に送信する。操作部100は、車載器20との通信を停止させるための操作をユーザから受けつける。通信部120は、操作部100が操作を受けつけた場合、操作部100が受けつけた操作に応じた通信停止に関する情報も含まれた第2信号を車載器20に送信する。制御部102は、通信部120において受信した第1信号の受信強度がしきい値以下となる場合に、通信部120に車載器20との通信を停止させる。【選択図】図2
