<p>PURPOSE: To prevent the effects on adaptive control of sudden events by storing a target value of an indication amount of gear shifting operation, averaging actual values to compare a average actual value to the target value to derive correction values, and modifying the pressure of hydraulic medium to drive- control engaging elements of a transmission. CONSTITUTION: A vehicular engine 10 is connected to a driven part 12 via a transmission. An engine speed generator 13 is arranged on the input side of the transmission 11 and a driven part revolution speed generator 14 is arranged on the output side. Furthermore, the transmission 11 is controlled by a speed change valve 15 and a pressure regulator 16. The speed change valve 15 is controlled by an electronic control valve 17, based on output signals from a position switch 18 and a throttle valve-signal generator 19, etc. A target value of indication values of gear shifting operation is stored, so that it can be called by addressing operating parameters and is compared to averaged actual value to derive correction value. Thereafter, the pressure of hydraulic medium is modified to drive-control engaging elements of the transmission.</p> |
