Provided is a hydraulic pressure control unit capable of evaluating the viscosity of a working fluid with good accuracy. In a hydraulic pressure control unit according to the present invention, a control device comprises: an evaluation unit that evaluates the viscosity of a working fluid; the evaluation unit evaluates the viscosity on the basis of the amount of decrease in the current value when the current value temporarily decreases while the current value of the current flowing through the winding (314) rises toward a target current value at the start of addition of the current to the winding (314) of the solenoid valve (31).
本发明得到能够精度良好地评价动作液的粘度的液压控制单元。在本发明所涉及的液压控制单元中,控制装置包括对动作液的粘度进行评价的评价部;评价部基于在电流向电磁阀(31)的绕组(314)的附加开始时流过绕组(314)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地下降时的电流值的下降量,对粘度进行评价。
