PURPOSE: To improve the controllability of automatic transmission by obtaining a coefficient of evaluation while comparing a real engine output with a first output characteristic curve and a second output characteristic curve, and temporarily filtering the continuously obtained real coefficient of evaluation so as to obtain the control parameter.
CONSTITUTION: The maximum engine output characteristic curve Pmax and a reference output characteristic curve Pref are regulated, and a first output characteristic curve PE related to the traveling speed is defined higher than the reference output characteristic curve Pref. A second output characteristic curve PS is defined between each characteristic curve PE and Pmax while corresponding the minimum coefficient of evaluation BZmin to the output characteristic curve PE. A real engine output PMot is obtained while corresponding the maximum coefficient of evaluation BZmax to the second output characteristic curve, and the engine output PMot is compared with the first and the second output characteristic curves PE, PS so as to obtain the real coefficient of evaluation BZa. This real coefficient of evaluation BZa is temporarily filtered so as to obtain a coefficient of evaluation BZf, and a control parameter for driving device is obtained on the basis of this coefficient of evaluation BZf.
