摘要：A drive power distribution device includes a hydraulic pressure sealing-typehydraulic pressure control device for making an operation noise of an on-off valve such asa solenoid valve less recognizable to occupants of a vehicle. By closing the on-off valve
and driving the oil pump, a hydraulic pressure detected using a hydraulic pressuredetection means reaches a target hydraulic pressure, and fastening power of a hydraulicclutch is maintained at an oil pressure of hydraulic fluid sealed in an oil passage until theon-off valve is opened. The drive power distribution device closes the solenoid valvewhen the hydraulic pressure is detected to be equal to or less than a predeterminedthreshold hydraulic pressure and equal to or less than a predetermined thresholdvehicle speed. This can prevent synchronization between an accelerator operation by adriver and a closing operation of the solenoid valve.
