To inhibit influence from being exerted on a circuit of a vehicle side.SOLUTION: An input circuit switching device 1 includes a voltage storage part 146 for storing voltage of a signal (e.g., a vehicle speed signal SV2) inputted from a vehicle 200 during a prescribed period PP, a first input circuit 11 for receiving the signal, a second input circuit 12 for receiving the signal and being different from the first input circuit 11, a comparison part 143 for comparing the value of the voltage with reference voltage VA, and a setting part 144 for performing setting such that the first input circuit 11 receives the signal when the value of the voltage is equal to or more than the reference voltage VA and such that the second input circuit 12 receives the signal when the value of the voltage is less than the reference voltage VA.SELECTED DRAWING: Figure 1

    【課題】車両側の回路に影響を与えることを抑制する。【解決手段】入力回路切換装置1は、所定期間PPにおいて車両200から入力される信号(例えば、車速信号SV2)の電圧を記憶する電圧記憶部146と、前記信号を受け付ける第1入力回路11と、前記信号を受け付け、第1入力回路11と相違する第2入力回路12と、前記電圧の値と、基準電圧VAとを比較する比較部143と、前記電圧の値が基準電圧VA以上である場合には、第1入力回路11が前記信号を受け付け、前記電圧の値が基準電圧VA未満である場合には、第2入力回路12が前記信号を受け付けるように設定する設定部144と、を備える。【選択図】図1
