    摘要： In a control unit of an automotive vehicle, it is possible to securely prevent a tie-up due to a miss-recognition of a disengage timing of a disengage side friction device, securely prevent an early disengage due to an erroneous recognition of the disengage timing and realize a control of accurately and reliably shifting the clutch. Accordingly, a control unit of an automatic transmission having pressure adjusting command generating means which executes a shift by engaging and disengaging a predetermined friction device in an automatic transmission connected to an engine and adjusts a hydraulic pressure acting on the friction device at a time of the shift is structured such as to have disengage timing recognizing means which recognizes a disengage timing of a disengage side friction device at a time of shifting the automatic transmission, first disengage determining means which determines a disengage operation of the disengage side friction device on the basis of a result of recognition by the disengage timing recognizing means and second disengage determining means which forcibly determines a disengage operation of the disengage side friction device in the case that it is impossible to recognize the disengage timing in the disengage timing recognizing means. In this control unit, the pressure adjusting command generating means operates so as to disengage the disengage side friction device on the basis of determination of the first and second disengage determining means.

    摘要： A hydraulic control apparatus for an automatic transmission accurately controls a variation in torque generated when a shift lever is turned from an N range into a D range or R range. The hydraulic control apparatus has a pressure governor for hydraulic pressure to be supplied from a spool valve to a clutch, by an actuator, thereby suppressing a variation in output torque of the automatic transmission. The hydraulic pressure governed by the actuator is introduced into the spool valve again, and it is supplied to a forward clutch and a reverse clutch through a hydraulic line switch for switching hydraulic lines communicated to the forward clutch and the reverse clutch from each other.
