Space-time fuzzy inference and applications using simplified time-change fuzzy set

In this paper, "Simplified time-change fuzzy set" is proposed aiming to simply provide the ambiguity of time change, such as "Distance is gradually near" to a computer. The proposed fuzzy set has four auxiliary sets, which enables the computer regarding the time change correctly based on the expert knowledge. It is applied to the lane change support system to let the computer determine the proper operation as a human expert under a dynamic environment. The obtained results indicated that the proposed method can let the computer regard the time change correctly in real time.
