PROBLEM TO BE SOLVED: To provide a vehicle portable machine capable of appropriately ensuring the wireless communication between the portable machine placed in a cabin and an on-vehicle device while suppressing unnecessary power consumption of the portable machine.SOLUTION: A vehicle portable machine holding a wireless communication with an on-vehicle device and including a control unit; comprises: a vibration unit supplying power to the control unit by a vibration; power supply holding means holding the supply of the power after starting the supply of the power to the control unit by the vibration; time discrimination means discriminating whether predetermined time passed after the supply of the power to the control unit starts; cabin interior discrimination means discriminating whether the wireless communication is held in a cabin after the supply of the power to the control unit starts; and power supply control means stopping the supply of the power to the control unit if it is discriminated the predetermined time passed and that the wireless communication is not held in the cabin, and continuing the supply of the power to the control unit using the power supply holding means if it is discriminated that the predetermined time did not pass and that the wireless communication is held in the cabin.
【課題】本発明は、車両用携帯機に係り、携帯機での無駄な電力消費を抑えつつ、車室内に置かれた携帯機での車載機との間の無線通信を適切に確保することにある。【解決手段】車載機との間で無線通信を行う制御部を備える車両用携帯機は、振動により制御部へ電源供給を行う振動部と、その振動により制御部への電源供給が開始された後、その電源供給を保持する電源保持手段と、制御部への電源供給が開始された後、所定時間が経過したか否かを判別する時間判別手段と、制御部への電源供給が開始された後、上記無線通信が車室内で行われているか否かを判別する車室内判別手段と、所定時間が経過したと判別されかつ無線通信が車室内で行われていないと判別される場合は制御部への電源供給を停止し、一方、所定時間が経過していないと判別され又は無線通信が車室内で行われていると判別される場合は電源保持手段を用いて制御部への電源供給を継続させる電源制御手段と、を備える。【選択図】図２
