发明名称 HYDRAULIC PRESSURE CONTROL APPARATUS FOR VEHICLE
摘要 The hydraulic control apparatus calculates a target engagement hydraulic pressure of a frictional engagement element, controls the frictional engagement element so that a revolution speed at a driving source side of the frictional engagement element is higher than a revolution speed at a driving wheel side of the frictional engagement element, outputs a command current to a solenoid valve on the basis of a map having a relationship between the target engagement hydraulic pressure and the command current, and decreases the engagement hydraulic pressure when a vehicle speed is equal to or less than a predetermined vehicle speed at which the vehicle is judged to be vehicle stop during execution of the slip control. Further, the hydraulic control apparatus corrects the map so that a variation of the command current with respect to a variation of the target engagement hydraulic pressure is small when decreasing the engagement hydraulic pressure.
