PROBLEM TO BE SOLVED: To provide a solenoid drive device capable of enhancing versatility while employing an arithmetic logic suitable for sampling of the value of a current flowing through a solenoid subjected to high frequency driving.SOLUTION: A brake control unit 3 performs duty control for a solenoid 1n by logic units 21n, 22n suitable for a frequency instruction value, by connecting the logic unit 21n for high frequency or the logic unit 22n for low frequency with a drive unit 30n of a predetermined CH depending on the frequency instruction value instructed from a microcomputer, and when the solenoid 1n for high frequency driving exceeds 4CH, performs high frequency driving of the solenoid 1n by selecting the logic unit 22n for low frequency. Consequently, the versatility of a brake ECU for vehicle can be enhanced while employing an arithmetic logic suitable for sampling of the value of a current flowing through the solenoid subjected to high frequency driving.SELECTED DRAWING: Figure 1

    【課題】高周波駆動されるソレノイドに流れる電流値のサンプリングに適した演算ロジックを採用しながら汎用性を高めることができるソレノイド駆動装置及び車両用ブレーキ制御装置を提供する。【解決手段】ブレーキ制御部3は、マイコンから指令された周波数指示値に応じて高周波用ロジック部21nまたは低周波用ロジック部22nと所定のCHの駆動部30nとを接続することで、周波数指示値に適したロジック部21n,22nによりソレノイド1nに対してデューティ制御を実行すると共に、高周波駆動するソレノイド1nが4CHを上回った場合は低周波用ロジック部22nを選択することによりソレノイド1nを高周波駆動する。これにより、高周波駆動されるソレノイド1nに流れる電流値のサンプリングに適した演算ロジックを採用しながら車両用ブレーキECUの汎用性を高めることができる。【選択図】図1
