VEHICULAR DOOR HANDLE DRIVE DEVICE AND VEHICULAR COMMUNICATION DEVICE
PROBLEM TO BE SOLVED: To provide a vehicular door handle drive device and vehicular communication device, capable of further downsizing an antenna.SOLUTION: A drive ECU 50 is electrically connected, through a first electric wire W1 and second electric wire W2, to a LF antenna 21 and DC driven sensor IC 30 capable of detecting a person's access or contact, the antenna and the sensor being mounted on an outside door handle 2 and connected in parallel with each other. The first electric wire W1 is always connected to a positive battery +B; the second electric wire W2 is grounded when the LF antenna 21 is not driven. The drive ECU also comprises: a step-up capacitor 56 having one terminal 56a connected to the battery +B; and an inverter INV to which the step-up capacitor 56's the other terminal 56b is connected, the inverter being connected (grounded) to a positive constant voltage circuit 53 and the ground. The inverter generates a rectangular wave voltage having a resonant frequency of the LF antenna 21 to output the voltage to the first electric wire W1 and the second electric wire W2 through the step-up capacitor 56.SELECTED DRAWING: Figure 2
【課題】アンテナをより小型化することができる車両用ドアハンドル駆動装置及び車両用通信装置を提供する。【解決手段】第１の電線Ｗ１及び第２の電線Ｗ２を介してアウトサイドドアハンドル２に搭載される互いに並列接続のＬＦアンテナ２１及び人の接近又は接触を検知可能な直流駆動のセンサＩＣ３０に電気的に接続された駆動ＥＣＵ５０であって、第１の電線Ｗ１が正極のバッテリ＋Ｂに常時接続されるとともに、ＬＦアンテナ２１の非駆動時に第２の電線Ｗ２が接地されており、バッテリ＋Ｂに一側端子５６ａが接続された昇圧用コンデンサ５６と、昇圧用コンデンサ５６の他側端子５６ｂが接続され、正極の定電圧回路５３及びグランドに接続（接地）され、ＬＦアンテナ２１の共振周波数を有する矩形波電圧を生成して昇圧用コンデンサ５６を介した第１の電線Ｗ１及び第２の電線Ｗ２に出力するインバータＩＮＶとを備える。【選択図】図２
