Intelligent Operation Support Method based on Time Change Fuzzy Sets

In the present paper, an effective support method for equipment operation under a dynamic environment is proposed. The proposed method presents operation instructions that the driver should be preparing to follow in the future. Using this method, the current and future states of the surrounding environment can be considered. The time change fuzzy set, which considers the state and time, to be universe of discourse. The time change fuzzy set is used for a computer as a buildup method with expert knowledge concerning the time change in the state. Experiments to support a lane change operation were conducted using a driving simulator. The obtained results indicated that the proposed method safely supports a lane change operation, and the time lag between the instruction being given by the system and operation being performed by the driver is decreased.
