PURPOSE:To increase the reliability of a controlling device by judging whether the rate of change of each of plural parameters is above a prescribed rate of change, and giving a command that the use of the corresponding parameter be forbidden when judged above the prescribed rate of change. CONSTITUTION:A driving part C drives a solenoid valve B which is provided on an automatic transmission A, and a controlling condition detecting means E detects plural parameters for determining the action of the transmission A. And, a controlling means F determines the action of the transmission A based on the detected results of the detecting means E and outputs a control signal to the driving part C. Further, a rate of change judging means G judges whether the rate of change of each of the plural parameters is above a prescribed rate of change or not, and a means H receives the signal of the judging means G and commands the forbidding of use to the control means F when above the prescribed rate of change. Thereby, the controlling means F determines the action of the transmission A based on parameters other than the parameters the use of which is forbidden, increasing the safety and reliability of a controlling device. |
