VEHICLE OPENING/CLOSING BODY LOCKING/UNLOCKING DEVICE
PROBLEM TO BE SOLVED: To obtain a small-sized and inexpensive vehicle opening/closing body locking/unlocking device capable of continuing a human detection function by using, as a power source, an antenna driving signal whose output is not limited by a Q value of an antenna even at the time of antenna driving at which DC power supply voltage is not supplied.SOLUTION: A vehicle opening/closing body locking/unlocking device comprises: an antenna (120) that includes a serial resonant circuit composed of a resonant capacitor (121) and an antenna coil (122) connected in series and an impedance adjustment resistor (123) connected in parallel to the antenna coil, and resonates with an antenna driving signal (V) to transmit authentication information for locking/unlocking a vehicle opening/closing body for a vehicle to a portable apparatus held by the vehicle's user; and a human detection IC (110) that, at the time of antenna driving at which DC power supply voltage is not supplied, operates by using the antenna driving signal as a power source to detect the user having come into contact with a human detection area of the vehicle opening/closing body.SELECTED DRAWING: Figure 2
【課題】直流電源電圧が供給されないアンテナ駆動時においても、出力がアンテナのＱ値によって制限されないアンテナ駆動信号を電力源として人検知機能を継続することができる小型で低コストな車両用開閉体の施解錠装置を得る。【解決手段】共振コンデンサ（１２１）とアンテナ用コイル（１２２）とが直列に接続された直列共振回路と、アンテナ用コイルに対して並列に接続されたインピーダンス調整用抵抗（１２３）とを有し、アンテナ駆動信号（ＶＡＣ）と共振することにより、車両の利用者が携帯する携帯機に、車両の車両用開閉体の施解錠のための認証情報を送信するアンテナ（１２０）と、直流電源電圧が供給されないアンテナ駆動時には、アンテナ駆動信号を電力源として動作することにより、利用者が車両用開閉体の人検知領域に接触したことを検知する人検知ＩＣ（１１０）と、を備える。【選択図】図２
