In one embodiment, an oil pressure control apparatus includes a belt-driven continuously variable transmission, a lockup clutch provided in a torque converter, a primary regulator valve that regulates a line oil pressure that becomes a source pressure of oil pressure of various parts, and a clamping oil pressure control valve that supplies a clamping oil pressure to a driven-side pulley of the belt-driven continuously variable transmission. Control of the primary regulator valve is performed with a control oil pressure of a linear solenoid valve that controls the clamping oil pressure control valve, and a control oil pressure of a linear solenoid valve that controls engagement/release of the lockup clutch. |
