PROBLEM TO BE SOLVED: To provide a door handle device for a vehicle for improving the accuracy of a determination based on a detection result by a sensor.SOLUTION: A door handle device 10 for a vehicle comprises: a handle 20; an unlock sensor 50 having a first drive electrode 51 and a first detection electrode 55; a lock sensor 60 having a second drive electrode 61 and a second detection electrode 65; an auxiliary sensor 70 having an auxiliary drive electrode 51 and an auxiliary detection electrode 71; and a sensor control part. The sensor control part performs first processing for detecting a voltage or a current generated at the unlock sensor 50, second processing for detecting a voltage or a current generated at the lock sensor 60, and third processing for detecting a voltage or a current generated at the auxiliary sensor 70 in a time division manner.SELECTED DRAWING: Figure 1B 【課題】センサによる検出結果に基づく判断の精度を向上する車両用ドアハンドル装置を提供する。【解決手段】車両用ドアハンドル装置１０は、ハンドル２０と、第１駆動電極５１と第１検出電極５５を有するアンロックセンサ５０と、第２駆動電極６１と第２検出電極６５を有するロックセンサ６０と、補助駆動電極５１と補助検出電極７１を有する補助センサ７０と、センサ制御部とを備える。センサ制御部は、アンロックセンサ５０に生じた電圧又は電流を検出する第１処理と、ロックセンサ６０に生じた電圧又は電流を検出する第２処理と、補助センサ７０に生じた電圧又は電流を検出する第３処理と、を時分割で実行する。【選択図】図１Ｂ
