  "textContent": "The present invention improves fuel efficiency of a vehicle and decreases a noise, by decreasing a margin value of a hydraulic pressure supplied to a hydraulic pressure control target and decreasing the hydraulic pressure supplied to the hydraulic pressure control target, when the vehicle is driven automatically. In a hydraulic pressure control device for a vehicle that controls a line pressure or an operation pressure (hydraulic pressure) supplied to a clutch or a transmission (hydraulic pressure control target) provided in the vehicle, the hydraulic pressure control device includes an operation pressure control unit (hydraulic pressure setting device) that sets margin values a and a of the operation pressure (line pressure) supplied to hydraulic circuits and of the clutch or the transmission , on the basis of a predetermined driving plan (refer to FIG. ) in the case of driving the vehicle automatically.",
