Vehicle hydraulic control device

A vehicle hydraulic control device including:

• an oil pump that is driven by a driving force source for wheels;
• and
• an oil passage that guides oil discharged from the oil pump to a rotating electrical machine that forms at least a part of the driving force source and a gear mechanism to which driving force from the driving force source is transmitted, wherein
• the oil passage includes a common oil passage connected to the oil pump, a first oil passage connected to the common oil passage to guide oil flowing from the common oil passage into the first oil passage to the gear mechanism, and a second oil passage branching off from a connection portion between the common oil passage and the first oil passage to guide oil flowing from the common oil passage into the second oil passage to the rotating electrical machine,
• a first relief valve and a throttle portion placed upstream of the first relief valve are provided in the first oil passage,
• a second relief valve is provided in the second oil passage,
• the first relief valve discharges oil in the first oil passage when an oil pressure in the first oil passage located downstream of the throttle portion becomes higher than a predetermined first set oil pressure,
• the second relief valve allows a part of the second oil passage which is located upstream of the second relief valve to communicate with a part of the second oil passage which is located downstream of the second relief valve when an oil pressure in the second oil passage located upstream of the second relief valve becomes higher than a predetermined second set oil pressure, and
• the second set oil pressure is set to an oil pressure higher than the first set oil pressure.
