To prevent a vehicle control device from being operated illicitly by external tools.SOLUTION: A portable machine (1) includes: a first signal generation unit (11) that transmits a first signal including a rolling code (31) and function code to a vehicle control device (2) depending on input operation from a user; a second signal generation unit (12) that transmits a second signal including the rolling code (31) but not including the function code to the vehicle control device (2) after transmitting the first signal; and a code update unit (13) that changes the value for the function code to a larger value or changes the code string for the function code to a subsequent code string every time the first signal is transmitted and every time the second signal is transmitted.SELECTED DRAWING: Figure 1

    【課題】外部ツールによって車両制御装置が不正動作させられることを防ぐ。【解決手段】携帯機(1)は、ユーザの入力操作に応じて、ローリングコード(31)と機能コードとを含む第1信号を車両制御装置(2)へ送信する第1信号生成部(11)と、第1信号を送信した後に、ローリングコード(31)を含むが機能コードを含まない第2信号を車両制御装置(2)へ送信する第2信号生成部(12)と、第1信号を送信する度、および、第2信号を送信する度に、機能コードの数値を大きい数値に変更する、または、機能コードの符号列を順序が後の符号列に変更するコード更新部(13)と、を備える。【選択図】図1
