PURPOSE:To improve speed change shock performance in a large degree by learning the dispersion and degraded parts of an engine and an automatic transmission minutely so as to make waveform at the time of speed change the target waveform. CONSTITUTION:The output shaft torque of an automatic transmission is sampled by a torque waveform detecting means (f). Speed change time, which is the torque fluctuation time, is computed by a speed change time computing means (g) from the detected torque waveform during speed change. The torque pop quantity, which is the integrated value of torque fluctuation, is computed by a torque pop quantity computing means (h). The speed change time is then compared to its target value by a first correction quantity updating means (i) so as to set the first correction quantity increasingly or decreasingly in the direction of coinciding with the target value. The first correction quantity data of a storage means (b) is reloaded, and the torque pop quantity is compared with its target value by a second correction quantity updating means (j) so as to set the second correction quantity increasingly or decreasingly in the direction of coinciding with the target value and rewrite the second correction quantity data of the storage means (b). |
