摘要： PURPOSE: A hydraulic control apparatus is provided to obtain calculation precision having high hysteresis hydraulic correction rate by preventing deviations of the hysteresis hydraulic correction rate from being accumulated depending on increase of return numbers while a minor loop is continuing. CONSTITUTION: A hydraulic control apparatus comprises an electromagnetic valve(2), a hysteresis hydraulic correction rate calculation unit, and an indication current control unit. The hysteresis hydraulic correction rate calculation unit has full hysteresis characteristics, indicating hysteresis for variable hydraulic characteristics, as a reference map. The variable hydraulic characteristics are comprised of an increased characteristic, in which indication current is changed from the minimum value to the maximum value, and a decreased characteristic, in which the indication current is changed from the maximum value to the minimum value. When a minor loop returning indication current on a position within ranges of the variable hysteresis characteristics is continued, reduction maps reducing the reference map depending on the return position is made up at each minor loop from the past to the current point. The hysteresis hydraulic correction rate is calculated by the sum of each hysteresis correction rate, getting from multiple reduction maps, at the same indication current position.
