摘要： In a vehicular hydraulic control circuit equipped with a mechanically-operated oil pump and an electrically-operated oil pump, a hydraulic control device is provided for reducing a high load imposed on the electrically-operated oil pump, when the electrically-operated oil pump is started during stoppage of the mechanically-operated oil pump. When the electrically-operated oil pump (72) is started from a state in which both the mechanically-operated oil pump (70) and the electrically-operated oil pump (72) are stopped, the mechanically-operated oil pump (70) is pre-started, and then the electrically-operated oil pump (72) is started. Therefore, oil pressure pre-generated by the mechanically-operated oil pump (70) can reduce a load imposed on the electrically-operated oil pump (72). As a result, excessive current that may occur in a control circuit for the electrically-operated oil pump (72) can be prevented.
