We apply a fuzzy reasoning method to a simulation of driving control for a model car. For the driving control in going straight on, we consider several fuzzy reasoning forms which come from the combination of the operations in antecedent parts, consequent parts, unification processes and defuzzifier procedures of the control rules. Their effects to the driving control are examined by the simulation using each reasoning form. The operations of the membership functions in the antecedent and consequent parts are a logical product and an algebraic product. We use a logical sum or an arithmetical sum as an operation to unify the outputs from the consequent parts. Three defuzzifier methods called the center-of-gravity method, the area method and Sugeno' s fuzzy reasoning method are also used. In the combination of these operations, we obtain 18 reasoning forms, which are applied to the simulation of the driving control. As a result, the best quality of the control is obtained in the case of the combination which consists of the area method for the defuzzifier procedure, the algebraic products for the antecedent and consequent parts, and logical sum for the unification process, i. e. the area method-algebraic product-algebraic product-logical sum.
