摘要:
A hydraulic pressure controller, which controls hydraulic pressure supplied to a torque converter including a lock-up clutch that is engageable using a hydraulic pressure from a mechanical pump, including a first pressure regulation valve that regulates pressure in a first passage connected to the pump while discharging oil in the first passage to a discharge passage; a bypass passage branched from the first passage bypassing the first pressure regulation valve; a first switching valve selectively switchable between a first state in which the bypass passage and a second passage are connected to each other and a second state in which the discharge passage and the second passage are connected to each other; and a second pressure regulation valve that regulates a hydraulic pressure in the second passage. The first switching valve is switchable into the first state to engage the clutch and into the second state to disengage the clutch.
