Document Type and Number:
Japanese Patent JP6812717
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a hydraulic control device and a program capable of restricting reduction in fuel consumption at a vehicle even if a product hydraulic characteristic shows a certain variation.SOLUTION: A hydraulic control device 10 comprises an electric current hydraulic characteristic information storage part 210 in which a driving current value of a solenoid valve and a measured hydraulic pressure of hydraulic fluid generated by the solenoid valve are adapted to each other and stored as electric current hydraulic characteristic information; a standard lower limit information storage part 220 in which a driving electric current value of the solenoid valve and a standard lower limit hydraulic pressure of the hydraulic fluid corresponding to the driving electric current are adapted to each other and stored as the standard lower limit information; a deviation calculation part 120 for calculating a deviation between the measured hydraulic pressure and the standard lower limit value on the basis of the electric current hydraulic pressure characteristic information and the standard lower limit value; a driving current correction part 130 for correcting a driving current of the solenoid valve on the basis of the deviation; and a driving electric current calculation part 140 for calculating the driving electric current value of the solenoid valve on the basis of a hydraulic target value, the electric current hydraulic pressure characteristic information and a post-correction driving electric current value.SELECTED DRAWING: Figure 2
