ABSTRACT:
A speed change control method for a vehicular automatic transmission, in which the transmission stage position of the automatic transmission having a plurality of transmission stages is changed to an optimum transmission stage set by fuzzy inference on the basis of parameter values indicative of the operating conditions of a vehicle. If a failure of any of sensors for detecting the parameter values concerned in the fuzzy inference is detected, setting the optimum transmission stage by the fuzzy inference is inhibited, and the optimum transmission stage is set in a speed change control mode which is not dependent upon the broken sensor. Thus, even in case of failure of a sensor, the vehicle can be driven without hindrance and without discomfort to a driver or fellow passengers.
