Hydraulic control apparatus

A hydraulic control apparatus for a vehicle, the vehicle comprising a prime mover and a power transmission mechanism, the power transmission mechanism comprising a driving unit driven by a hydraulic force and a lubrication unit to which a lubricating oil is supplied and being configured to transmit a torque output from the prime mover to a driving wheel in response to driving of the drive unit, the hydraulic control apparatus comprising:

• a first hydraulic pump;
• a second hydraulic pump;
• a first flow path configured to lead an oil discharged from the first hydraulic pump to the driving unit;
• a second flow path configured to lead an oil discharged from the second hydraulic pump to the lubrication unit;
• a third flow path configured to lead the oil discharged from the second hydraulic pump to the first flow path;
• a flow path switching unit configured to switch a flow path so as to lead the oil discharged from the second hydraulic pump to the lubrication unit through the second flow path or to the first flow path through the third flow path;
• an operation detector configured to detect an operation or inoperation of an accelerator;
• a vehicle speed detector configured to detect a vehicle speed;
• and
• a controller configured to control the flow path switching unit so as to lead the oil discharged from the second hydraulic pump to the first flow path when the inoperation of the accelerator is detected by the operation detector and a vehicle speed less than or equal to a predetermined value which is greater than 0 is detected by the vehicle detector, and to lead the oil discharged from the second hydraulic pump to the lubrication unit when the operation of the accelerator is detected by the operation detector or a vehicle speed greater than the predetermined value is detected by the vehicle speed detector.
