Title:
油圧回路の異常検知装置、及び、油圧回路の異常検知方法
Document Type and Number:
Japanese Patent JP6267250
Kind Code:
B2
Abstract:
An abnormality detection device for a hydraulic circuit including an oil pump, a switching unit switching between a fully discharged state and a partial discharge, a pressure regulator, a pressure regulation controller and a hydraulic detector, The device includes: a storage storing a maximum discharge pressure of oil capable of being discharged in the partially discharged state; a switching controller performing control of switching into the fully discharged state; and a determination unit determining that the switching unit has a fixation abnormality of the partially discharged state when a hydraulic pressure approximately corresponds to the maximum discharge pressure in the partially discharged state in a state where a hydraulic pressure higher than the maximum discharge pressure in the partially discharged state is set as a target hydraulic pressure and the pressure regulator is controlled in an effort to achieve the target hydraulic pressure after the switching control.
