    摘要： Vehicle automatic transmission control system in which based on the determined operating parameters of the vehicle including degree of throttle opening, vehicle speed or the like, a plurality of sets of membership functions of the parameters are established in accordance with a plurality of sets of predetermined fuzzy production rules. Fuzzy reasoning is carried out on the sets of the rules to determine a target gear ratio to shift to. The plural sets of the rules are predetermined hierarchically. One category of rules is directed toward the entire area of shift control, whereas another category of rules is directed toward a specific shift control area such as hill climbing. Further an additional category of rules is provided to presume the driver's intentional condition such as an intention to decelerate. Based on the last category of rules, fuzzy reasoning is carried out to determine the intentional condition. The condition thus obtained is added to the first-mentioned parameters and the second fuzzy reasoning is carried out to determine the target gear ratio on the basis of the first and second category of rules.

    摘要： A system for controlling automatic, multi-step or continuously variable, transmission equipped with a motor vehicle utilizing fuzzy logic. In the system, fuzzy production rules have been prepared based upon an expert driver's judgments and operation made on a vehicle with a manually shifted transmission. Various operating conditions including opening degree of a throttle valve and road speed of the vehicle are detected and from the detected value, various predictions are made such as an appropriateness of vehicle response determined from the reserve motive force with respect to a gear ratio shift intended by the driver and engine output change that would occur should the transmission be shifted to the gear ratio. These measured or estimated value are put on a common scale named universe of discourse and membership values of the rules are sucessively calculated. Among the rules, one rule is finally selected and according to the gear ratio indicated in the selected rule, the current gear ratio is shifted up or down or is held at the present ratio. Similarly, the speed ratio in the continuously variable transmission is determined from the selected rule.

    摘要： A vehicle control system embodied as an autocruise control. Fuzzy Logic is introduced in the system such that an expert driver's operation or judgment made on an non-automated vehicle is able to be incorporated in the system as fuzzy production rules. In the system, the control is effected in accordance with the rules which can be expressed linguistically in a simple manner and has a predictive nature therein. Operating condition of the vehicle is detected through parameters such as a vehicle speed, a vehicle acceleration and a change of vehicle acceleration which are then assigned on a scale named universe of discourse. The satisfaction degree is evaluated so that one rule is selected. A control value is determined from the selected rule which is output to an actuator to be controlled.

    摘要： An air/fuel ratio control system for an internal combustion engine provides a mixture leaner than a predetermined reference value when a detected engine load is in a light load range. In order to produce a required engine power during a transitional period, the system detects the speed of variation of an operating parameter used for the calculation of air/fuel ratio and controls the air/fuel ratio toward the reference level even though the magnitude of the detected engine load is in the light load range. Preferably, an EGR rate is also made smaller upon occurrence of a rapid change of the operating parameter so as to prevent the power down of the engine during the transitional period.
