摘要： An apparatus for controlling the amount of slip of a lock-up clutch between pump and turbine impeller of a torque converter or other fluid-filled power transmitting device in a motor vehicle, the lock-up clutch including a piston which is operated by a pressure difference between pressures in two oil chambers on the opposite sides of the piston, and the apparatus including a slip control device for controlling the lock-up clutch according to a slip control output such that the actual slip of the lock-up clutch coincides with a target slip speed, and an output oscillating device for oscillating the slip control output to oscillate the pressure difference without vibrating the piston. The slip control output is oscillated preferably when the pressure difference is relatively small, for example, when the torque of the lock-up clutch is smaller than a threshold or the vehicle deceleration rate is higher than a threshold, or when the target slip speed determined depending upon the vehicle running condition is almost equal to the actual slip speed.

摘要： A control apparatus and method control a torque of an engine coupled to an input shaft of an automatic transmission during a shift by that automatic transmission. A torque-down control by which the engine torque is decreased by a predetermined amount is performed, a torque-restore control starting point at which time torque-restore control is to be started is determined, and the torque-restore control so as to gradually restore the engine torque to a value before the torque-down control was performed is started at the torque-restore control starting point. The torque-restore control starting point is determined according to a dynamic model which simulates behavior of the automatic transmission over time from start of the torque-down control, so that a rotational speed of the input shaft of the automatic transmission at a target point substantially matches a target speed.

摘要： A characteristics change of a control object is functionally represented by a parameter &thgr; which varies between values of 0 and 1 as the gain of the control object is surveyed. The frequency of the identification signal is set at a frequency where the difference in gains becomes large. The amplitude of the identification signal is set so that the variation width of the output of the control object is less than or equal to a predetermined value. Because the identification accuracy improves where the input/output characteristics with respect to the parameter are more sensitive, the identification signal set by such a setting apparatus imparts high identification accuracy. Moreover, because the amplitude of the identification signal is set based on the variation width of the output of the control object, identification can be performed without significantly affecting the output of the control object.
摘要翻译：在控制对象的增益被调查的情况下，控制对象的特征变化在功能上由参数θ表示，该参数θ在0和1的值之间变化。识别信号的频率被设定为增益差变大的频率。识别信号的幅度被设定为使得控制对象的输出的变化幅度小于或等于预定值。由于相对于参数的输入/输出特性更敏感，因此识别精度提高，所以由这种设定装置设定的识别信号具有高识别精度。此外，由于基于控制对象的输出的变化宽度来设定识别信号的幅度，因此可以在不显着影响控制对象的输出的情况下进行识别。

摘要： The present invention realizes high-speed and stable controls irrespective of the characteristic perturbations accompanied with the variation in operation point of a plant. The principle of the invention is applied to slip control of a lock-up clutch of a transmission and to idling engine speed control. A plant input calculation unit OC working as a controller recognizes an actual plant plus a characteristic compensator CC as an augmented plant EOB. The characteristic compensator CC compensates for the characteristic perturbations of the augmented plant EOB accompanied with the variation in operation point, so that the augmented plant EOB always works at a design point with respect to the plant input calculation unit OC working as the controller. The characteristic compensator CC compensates for frequency-dependent gain and phase deviations through filter operations and for a stationary gain deviation by multiplying predetermined constants.

摘要： An apparatus for controlling a lock-up clutch between pump and turbine impellers in a power transmitting system of a motor vehicle, including a slip control device for controlling the amount of slip of the lock-up clutch, and a judder detector for detecting a judder of the lock-up clutch based on the number of detected speed variations of the turbine impeller during slip control of the lock-up clutch by the slip control device, wherein the judder detector is inhibited from using a variation of the turbine impeller speed variation for the detection of the judder, if the amount of change of the variation amplitude is larger than a predetermined threshold or if the period of the variation is outside a predetermined range. The judder detector is preferably arranged to operate on the basis of the variation amplitude of the turbine impeller speed as compared with the variation amplitude of the output speed of an automatic transmission multiplied by the actual speed ratio of the transmission, or on the basis of a phase difference between the variation waveforms of the turbine impeller and transmission output speeds.
