Abstract: An air fuel ratio detecting device has an air-fuel ratio sensor for producing an air-fuel ratio information indicative of the concentration of oxygen in an exhaust gas produced by a burned air-fuel mixture in the internal combustion engine. An air-fuel ratio is calculated on the basis of the air-fuel ratio information.

The air-fuel ratio is corrected with the pressure difference. The corrected air-fuel ratio is free of pressure fluctuations of the exhaust gas, and is highly reliable for accurate air-fuel ratio control.

Abstract: A shift pattern control for a multiple speed ratio transmission wherein an inference-based control overrides the normal shift pattern to automatically achieve manual pulldown operation under conditions for which such operation would be advised and expected. The inference-based control is achieved with a fuzzy logic technique by which vehicle parameters influencing the desirability of manual pulldown operation are measured or estimated, and used to establish an aggregate measure of the overall need for engine braking and downshifting. In the preferred embodiment, the fuzzy logic parameters include vehicle speed, grade load, engine throttle position, time of braking and time of deceleration. The parameters are applied to membership functions to indicate the truthfulness of the specified conditions, and logical combinations of the truth indications are formed, weighted to reflect their criticality, and combined to form an aggregate measure of the overall need for pulldown operation.

Abstract: An improved adaptive line pressure control which detects the occurrence of run-through and overrides the normal adaptive pressure control in response to a detected run-through condition so that the line pressure during subsequent shifting is increased instead of decreased. A run-through condition is detected by periodically sampling the transmission speed ratio in the course of the inertia phase of an upshift from a lower speed ratio to an upper speed ratio, and determining the average ratio for the upshift. If the average ratio is within a reference amount of the normal value (ratio midpoint), the adaptive control is allowed to update the adaptive pressure value in relation to the difference between the measured shift time and a desired shift time. If the average ratio exceeds the normal value (midpoint) by more than the reference amount, a run-through is detected, and the adaptive pressure amount is increased regardless of the measured shift time.
