To provide a vehicle hydraulic pressure control device that can curb a decrease in line pressure while preventing an excessive load on a motor-driven oil pump.SOLUTION: An electronic control device (hydraulic pressure control device) 90 is for a vehicle 10 comprising: a first electric motor MG1 which is connected to a power transmission path PT between an engine 12 and a pair of drive wheels 32 so as to be able to transmit power and can output reaction torque with respect to output torque of an engine 12; a second electric motor MG2 which is connected to the power transmission path PT so as to be able to transmit power and can output torque to the pair of drive wheels 32; an MOP 16 which is driven by the engine 12; and an EOP 46. When shifting a drive power source from the engine 12 to the second electric motor MG2 while the vehicle 10 is in operation, the electric control device repeats increase control, causing the first electric motor MG1 to increase an MOP rotation speed Nmop while the EOP 46 is in operation and an engine rotation speed Ne is decreasing, a predetermined number of three times.SELECTED DRAWING: Figure 1
