Abstract
A vehicle control system embodied as an autocruise control. Fuzzy Logic is introduced in the system such that an expert driver's operation or judgment made on an non-automated vehicle is able to be incorporated in the system as fuzzy production rules. In the system, the control is effected in accordance with the rules which can be expressed linguistically in a simple manner and has a predictive nature therein. Operating condition of the vehicle is detected through parameters such as a vehicle speed, a vehicle acceleration and a change of vehicle acceleration which are then assigned on a scale named universe of discourse. The satisfaction degree is evaluated so that one rule is selected. A control value is determined from the selected rule which is output to an actuator to be controlled.
