ABSTRACT

A t the beginning o f this Section II .C on fuzzy logic, we stated that human knowledge structured in the form o f IF -THEN rules represented mapping, or a multivariate function, which maps the input variables (IF part variables, antece­ dents, causes) into the output ones ( T H E N part variables, consequents, effects). Now, in closing this part on F L M , we w i l l illustrate this fact by showing how our common knowledge in controlling the distance between our car and the vehicle in front o f us while driving, is indeed a function. In order to show this function graphically, we restrict the input variables to the two most relevant to this control task: the distance between the two vehicles and the speed.
