摘要： A hydraulic pressure control apparatus includes: a solenoid valve; a hysteresis hydraulic pressure correction amount calculation section configured to calculate a hysteresis hydraulic pressure correction amount; and a command current control section configured to control the command current in accordance with the hysteresis hydraulic pressure correction amount, the hysteresis hydraulic pressure correction amount calculation section having, as a reference map, a full hysteresis characteristic, and being configured to make a plurality of reduction maps each of which is obtained by reducing the reference map in accordance with a turn-round position at one of minor loops from a past to a present time when the minor loop continues, and to calculate the hysteresis hydraulic pressure correction amount by summation of the hysteresis hydraulic pressure correction amounts obtained by the plurality of the reduction maps in the same command current position.
