Abstract
A hydraulic control device includes an electric pump configured to supply oil to a belt-type continuously variable transmission mechanism of a power transmission device through a hydraulic path based on driving of a motor, and an accumulator configured to accumulate oil inside by using the oil supplied by the electric pump and supplies the oil to a control system by discharging the accumulated oil through the hydraulic path. According to such a configuration, an increase in the sizes of the electric pump and the accumulator used for hydraulic control at the time of executing an idling stop function can be suppressed.
