The invention provides a hydraulic control unit capable of estimating the stroke amount of an armature of a solenoid valve with good precision. A hydraulic pressure control unit according to the present invention is provided with: an estimation unit that estimates the stroke amount ([delta] x) of an armature (312) of a solenoid valve (31); the estimation unit estimates a stroke amount ([Delta] x) on the basis of a decrease amount of a current value when the current value temporarily decreases in a process in which the current value of the current flowing through a winding wire (314) at the start of application of the current to the winding wire (314) of the solenoid valve (31) rises toward a target current value.
本发明得到能够精度良好地推测电磁阀的电枢的行程量的液压控制单元。在本发明的液压控制单元中,控制装置包括推测电磁阀(31)的电枢(312)的行程量(Δx)的推测部;推测部基于在向电磁阀(31)的绕线(314)的电流的施加开始时流到绕线(314)中的电流的电流值朝向目标电流值上升的过程中电流值暂时性地下降时的电流值的下降量来推测行程量(Δx)。
