Title:
車両用油圧制御装置
Document Type and Number:
Japanese Patent JP7035633
Kind Code:
B2
Abstract:
To provide a hydraulic control device for a vehicle capable of suppressing delay in starting a vehicle even when a R contact point is fixed in an on state.SOLUTION: When switching from ON to OFF of a D contact point is detected in a step S50 after detecting that both of the D contact point and a R contact point are in an ON state in a step S10, a hydraulic control device 120 for a vehicle doubts that the R contact point is fixed in the ON state, and does not execute B1 engagement transient control to increase an electric value of SLG current of a third linear solenoid valve SLG after decreasing the same, but executes B1 engagement steady pressure control to keep the current value of the SLG current at a large value in a step S80. For example, as engagement of an engagement clutch S1 is not disengaged even when a shift lever 74 is operated to a N range position, and re-engagement of the engagement clutch S1 is not necessary even when the shift lever 74 is operated to the R range position thereafter, the delay in starting the vehicle 10 is suppressed.SELECTED DRAWING: Figure 11
