  • Patent number: 11480247
    Abstract: A control device controls a lockup clutch interposed between an engine and an automatic transmission mechanism of a vehicle. The control device includes a control part supplying hydraulic pressure to the lockup clutch and controlling differential pressure of the lockup clutch. The control part supplies the hydraulic pressure to the lockup clutch so that the differential pressure is lower than a reference differential pressure in a disengaged state of the lockup clutch. In a case of shifting the lockup clutch from the disengaged state to an engaged state, the control part supplies the hydraulic pressure to the lockup clutch so that the differential pressure increases as a filling ratio of an oil passage of the lockup clutch decreases. The reference differential pressure is a lower limit of the differential pressure that increases a slip ratio of the lockup clutch or reduces a slip amount of the lockup clutch.

  • Patent number: 11466772
    Abstract: Provided is a hydraulic control device in which in the rotation control of the second pump, the required discharge pressure of the second pump can be more reliably maintained below a predetermined pressure in the control that keeps the target rotation speed constant after the feedback control ends. In the rotation control of the second pump, in the control which keeps the target rotation speed constant after the feedback control ends, the rotation of the second pump is controlled by adding a predetermined addition rotation speed to the target rotation speed corresponding to the required discharge pressure. Since the required discharge pressure of the second pump can be maintained below a predetermined pressure in the fixed mode by the addition rotation speed, it can reliably obtain the effect of reducing the work load of the first pump and contribute to the improvement of the fuel efficiency of the vehicle.

  • Patent number: 11466773
    Abstract: The disclosure provides a hydraulic control device. The operating/stopping of the second pump is determined based on a value of a difference between a reduced work rate of the first pump when the second pump is operated and a power consumption of the second pump. In a state where the second pump is stopped, the power consumption of the second pump is calculated based on an estimated value of a pressure of oil supplied to the hydraulic operation part and an estimated value of a pressure of oil supplied from the first pump to another hydraulic operation part or a lubrication target operating at a lower pressure than the hydraulic operation part. In a state where the second pump is operated, the power consumption of the second pump is calculated based on an actual rotation speed and an actual torque of the second pump.
