ABSTRACT:
A method of input power on/off discrimination for an automatic vehicular transmission system having an input shaft to which an output torque of an engine is transmitted, the method being adapted, for example, for the selection of the transmission control logic of the transmission system. The output torque of the engine transmitted to the input shaft is detected. If the detected output torque takes a value such that the rotating speed changing rate of the input shaft during transmission control is higher than a predetermined target value, it is concluded that the engine is in the power-on state. Preferably, the output torque of the engine is transmitted to the input shaft of the transmission system through a driving force transmission apparatus capable of detecting transmission torque. In this case, the speed changing rate of the engine and the transmission torque of the driving force transmission apparatus are detected, and the detected transmission torque and the product of the detected engine speed changing rate and a predetermined value are added so that the resulting sum is used as the value of the output torque of the engine. The power-on or -off state is discriminated by the output torque thus calculated.
