    • 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.

    • An apparatus for controlling an automatic transmission of an automobile and a control method thereof. When a feedback control is executed by the automatic transmission while the speed is being changed, the control operation may often lose stability. This is due to a large deviation between a target value and a practical value at the start of the feedback control operation being caused by a change in the opening degree of the throttle and a change in the oil temperature in the automatic transmission. To solve such a technical problem, the invention employs a control apparatus which detects that the automatic transmission is changing the speed, operates the output shaft torque of the automatic transmission, recognizes a point of inflection of the output shaft torque while the speed is being changed, sets a target output shaft torque of the automatic transmission, and sets an initial target value at a moment of said point of inflection.
    • 一种用于控制汽车自动变速器的装置及其控制方法。 当速度改变时通过自动变速器执行反馈控制时,控制操作可能经常失去稳定性。 这是由于由于节气门开度的变化和自动变速器中的油温的变化而引起的反馈控制动作开始时的目标值与实际值之间的大的偏差。 为了解决这样的技术问题,本发明采用了一种控制装置,其检测到自动变速器正在改变速度,操作自动变速器的输出轴转矩,在速度改变时识别输出轴转矩的拐点 设定自动变速器的目标输出轴转矩,并且在所述拐点的瞬间设定初始目标值。
