    • An in-gear oil pressure correcting section corrects engagement control oil pressure set up by an oil pressure supply control section over the entire range to be reduced by first predetermined pressure. An engagement determining section determines, on the basis of a torque converter slip ratio calculated by a calculating section, whether a frictional engagement element of a destination gear starts to engage or not. An addition correcting control section corrects the corrected engagement control oil pressure to add second predetermined pressure thereto in the case where engagement of the frictional engagement element has not been started yet when a timer measures first predetermined time. The addition correcting control section further corrects the corrected engagement control oil pressure to add third predetermined pressure thereto in the case where the engagement of the frictional engagement element has not been started yet when the timer measures second predetermined time.
    • 齿轮油压校正部在整个范围内校正由油压供给控制部设定的接合控制油压,使其降低第一预定压力。 接合确定部分基于由计算部分计算的变矩器滑移比来确定目的地齿轮的摩擦接合元件是否开始啮合。 当定时器测量第一预定时间时,在摩擦接合元件的接合尚未开始的情况下,附加校正控制部分校正校正的接合控制油压以增加第二预定压力。 当定时器测量第二预定时间时,在摩擦接合元件的接合尚未开始的情况下,加法校正控制部分进一步校正校正的接合控制油压以增加第三预定压力。

    • A hydraulic pressurizer system 30 comprises a drive source (an engine 2 and a motor generator 4), which drives a hybrid vehicle 1, a mechanical oil pump 20, which is driven by the drive source, an electrical motor 22, which is activated by a 12V battery 24, an electrical oil pump 21, which is driven by the electrical motor 22, and a control unit 15, which activates the electrical motor 22. The pressurizer further comprises a ratio-change mechanism 7, which is activated by hydraulic oil supplied by the mechanical oil pump 20 and by the electrical oil pump 21 to establish a speed change ratio, at which the rotational driving force of the drive source is transmitted to wheels 8 with a rotational speed change. For executing a control for stopping the drive source, the control unit 15 executes a cleaning operation, which operates the electrical oil pump 21 for a predetermined time before the stopping of the drive source.

    • A control device for a vehicle controls a motor-driven pump at an appropriate timing when an internal combustion engine is stopped or starts. An ECU of the control device comprises an operation determination section which determines whether or not the motor-driven pump is operated depending on the value of an idling stop flag that makes the internal combustion engine stop, depending on a measured value output from an oil pressure sensor for measuring oil pressure in oil lines providing operation oil to a torque converter and a transmission, and depending on a measured value output from an oil temperature sensor for measuring the temperature of the operation oil; and a target electrical current calculation section for calculating a target value of electrical current to be supplied during the operation of the motor-driven oil pump depending on the determination result by the operation determination section. The target electrical current calculated by the target electrical current calculation section is input to a driving section of the motor-driven oil pump, and the driving section provides driving electrical power to the pump depending on the target electrical current.
