    摘要： A control device for controlling a continuously variable transmission (5) is disclosed. The control device has an oil pressure control unit (100) which supplies an oil pressure to a primary pulley (10) and secondary pulley (11) based on a command signal indicative of a target speed-reduction ratio, a sensor (26) which detects a rotation speed (Np1) of the primary pulley (26), and a controller (20) which transmits the command signal indicative of the target speed-reduction ratio to the oil pressure control unit (100). The controller is programmed to set the target speed-reduction ratio to a first speed-reduction ratio (R1); calculate a first predetermined rotation speed (N1) of the primary pulley at which the V-belt reaches a first limiting temperature (T1) at the first speed-reduction ratio (R1); calculate a first elapsed time after the detected rotation speed (Np1) of the primary pulley exceeds the first predetermined rotation speed (N1); maintain the first speed-reduction ratio (R1) when the first elapsed time is equal to or less than a first predetermined time; and set the target speed-reduction ratio to a second speed-reduction ratio (R2) smaller than the first speed-reduction ratio (R1) when the first elapsed time exceeds the first predetermined time. At the second speed-reduction ratio (R2), the temperature of the V-belt should become equal to or less than the first limiting temperature (T1) throughout the permitted rotation speed region of the primary pulley. Thus, starting acceleration performance of the continuously variable transmission is enhanced.

    摘要： An oil pressure control device, which changes a range of a vehicle transmission includes: a pressure adjusting device that engages or releases forward and reverse frictional-engagement devices by adjusting an oil pressure supply, a sensor that detects a range selected by a vehicle driver, and a controller that controls the clutch pressure adjusting device based on a signal from the sensor. When the stop range is selected after selecting the reverse (forward) range, a forward (reverse) range is selected. After supplying an initial oil pressure to the forward (reverse) frictional-engagement device, the pressure adjusting device is controlled so that the pressure decreases from the initial oil pressure to a predetermined oil pressure. Subsequently, the oil pressure is initially increased at a small increase rate from the predetermined oil pressure. After a predetermined time period has elapsed, the pressure adjusting device increases the oil pressure at a large increase rate.

    摘要： After an engine (1) has started, a controller (6) starts determining whether lockup should be prohibited or permitted based on the cooling water temperature of an engine (1) or the oil temperature of a transmission (2). Once it has been determined that lockup should be permitted, the controller (6) stops determining whether lockup should be prohibited or permitted until the next time the engine (1) is started. In this way, once the conditions for determining that lockup should be permitted hold, lockup prohibition or permission based on the engine cooling water temperature or transmission oil temperature is no longer determined, so repeat engaging and disengaging of the lockup clutch (5) due to fluctuations of engine cooling water temperature or transmission oil temperature, is prevented.

    摘要： A control apparatus of an automatic transmission has an engagement part, a power-ON/OFF state judgment section and a control section controlling a capacity of the engagement part. The control section compares an actual input revolution speed difference absolute value of an absolute value of a difference between an input revolution speed when engaged and an actual input revolution speed with a target input revolution speed difference absolute value of an absolute value of a difference between the input revolution speed when engaged and a target input revolution speed, then a deviation is determined by subtracting the target input revolution speed difference absolute value from the actual input revolution speed difference absolute value. When the deviation is positive, the capacity is increased. When the deviation is negative, the capacity is reduced. When the deviation is zero, a previous capacity that is set before the comparison of the both absolute values is maintained.

    摘要： A control system controls an automatic transmission. The automatic transmission comprises a stepwise variable transmission section that includes a plurality of frictional elements and establishes a desired speed by a shift change disengaging one of the frictional elements and engaging the other of the frictional elements and a continuously variable transmission section that establishes a desired speed continuously. The control system makes a speed change control of the continuously variable transmission section cooperate with a change of an input rotation speed of the stepwise variable transmission section. The control system is configured to carry out during the shift change of the stepwise variable transmission section, judging whether a delivery of a torque from a disengaging side frictional element to an engaging side frictional element is completed or not; and starting the speed change control of the continuously variable transmission section upon judgment of the completion of the delivery of the torque regarding that an inertial phase has started.

    摘要： There are provided with a determination means for determining whether or not the correlation between the pressure value detected by the primary pressure sensor and the pressure value detected by the secondary pressure sensor is an actually impossible relation (Step 5), and a switchover means for switching over to an open control while prohibiting a feedback control when the correlation is determined to have become a relation actually impossible by the determination means (Step 6). Presence or absence of a fault to the primary pressure sensor or the secondary pressure sensor (particularly, fault of fixed output voltage) is judged based on the correlation between the output voltage of the primary pressure sensor and the output voltage of the secondary pressure sensor to prohibit the control of a primary pressure and a secondary pressure using the hydraulic pressure sensors when it is judged that there is a fault.
