The consistency of the rule-base is an essential basis for the rule-based intelligent information processing. In the framework of first-order lattice-valued logic system LF(X) which is in the attempt of handling fuzziness and incomparability, the present work focus on how to verify and increase the consistency degree of the rule-base in the intelligent information process system for handling fuzziness and incomparability. An alpha -automated simplification algorithm in LF(X) is proposed, the alpha -consistency and the alpha -simplification theory of the rule-base are formulated As such, the verification of the alpha -consistency of the rule-base, often an infinity problem which is difficult to be achieved, can be transformed into a finite and achievable alpha -simplification problem. Based on the theory, an alpha -simplification stepwise search algorithm for verifying the consistency of the rule-base as well as a kind of filtering algorithm for increasing the consistency degree of the rule-base are proposed.

This paper takes the four needs of people for driving, i.e., safety, comfort, reliability and low consuming, as the design objective of the vehicle driving automatic control system, and brings forward a linguistic control model of vehicle driving based on the analysis of the four related factors of vehicle driving, i.e., driver, vehicle, road and environment, which provides a certain basis for further steps taken in designing the autonomous vehicle driving system mimicking human driving.
