OPERATION DETECTOR FOR VEHICLE
To properly separate a change in capacitance to be extracted from noise.SOLUTION: An operation detector for a vehicle includes: an output circuit which outputs an output signal relating to opening/closing of a vehicle door according to a change in the capacitance of a sensor electrode; a first detection unit which repeatedly detects the capacitance of the sensor electrode and outputs it as a first detection signal over time; and a second detection unit which repeatedly detects the capacitance of the sensor electrode at a timing different from the first detection unit and outputs it as a second detection signal over time. An output circuit multiplies the first detection signal and the second detection signal to generate a multiplication composite signal. The output circuit outputs an output signal relating to the opening/closing of the vehicle door when the value of a multiplication composite signal P2 for one of the adjacent sensor electrodes becomes a first prescribed capacity value C1 or more and the value of a multiplication composite signal P3 for the other sensor electrode becomes the first prescribed capacity value C1 or more within a first prescribed time.SELECTED DRAWING: Figure 5
【課題】抽出したい静電容量の変化を、適切にノイズと切り分ける。【解決手段】車両用検出装置は、センサ電極の静電容量の変化に応じて、車両ドアの開閉に関する出力信号を出力する出力回路と、センサ電極の静電容量を繰り返し検出して第１検出信号として経時的に出力する第１検出部と、センサ電極の静電容量を、第１検出部とは異なるタイミングで繰り返し検出して第２検出信号として経時的に出力する第２検出部とを備える。出力回路は、第１検出信号と第２検出信号とを乗算して乗算合成信号を生成する。出力回路は、隣り合うセンサ電極のうちの一方のセンサ電極についての乗算合成信号Ｐ２の値が第１規定容量値Ｃ１以上になってから、第１規定時間以内に他方のセンサ電極についての乗算合成信号Ｐ３の値が第１規定容量値Ｃ１以上になった場合に、車両ドアの開閉に関する出力信号を出力する。【選択図】図５
