Patent ID: 7018315

Claim:
A hydraulic control apparatus for a vehicle, comprising: an electric oil pump; a pump control portion which controls the electric oil pump; a hydraulic circuit portion which supplies a hydraulic pressure from the electric oil pump to an actuator of a transaxle of the vehicle; a hydraulic circuit control portion which outputs a control signal to the hydraulic circuit portion; an oil pump rotation control portion which is provided in the pump control portion and which controls a rotational state of the electric oil pump according to a change in a control status of the hydraulic circuit control portions; an operation state determining portion which determines an operation state of the vehicle; and a hydraulic pressure determining portion which determines whether a hydraulic pressure in the hydraulic circuit portion of the vehicle needs to be in a low hydraulic pressure region or in a high hydraulic pressure region based on a result of determination made by the operation state determining portion, wherein the hydraulic circuit control portion computes the control signal based on the result of determination made by the operation state determining portion, and the oil pump rotation control portion controls a rotational speed of the electric oil pump based on a result of determination made by the hydraulic pressure determining portion.
