To provide a vehicle controller, a variable reception range system and a portable device capable of suppressing power consumption of a battery provided in the portable device.SOLUTION: An out of execution range determination unit 14b determines that a portable device exists in a reception range 30 and outside of an execution range 31 if received strength is a first threshold value or less. In this case, a sensitivity reduction request unit 15a transmits a reception sensitivity reduction request to the portable device. The sensitivity reduction request unit 15a narrows the reception range 30 until the portable device cannot receive a response request signal. Therefore, the number of replies of the portable device corresponding to the response request signal becomes smaller.SELECTED DRAWING: Figure 2

    【課題】携帯機が備える電池の消費を抑制する車両制御装置、受信範囲可変システムおよび携帯機を提供する。【解決手段】実施範囲外判断部14bは、受信強度が第1の閾値以下の場合、受信範囲30内かつ実施範囲31外に携帯機が存在すると判断する。この場合、感度低下要求部15aは、受信感度低下要求を携帯機へと送信する。感度低下要求部15aは、携帯機が応答要求信号を受信できなくなるまで、受信範囲30を狭くさせる。これにより、応答要求信号に対して携帯機が返信する回数が少なくなる。【選択図】図2
