Fuzzy expert system for automatic transmission control
H.-G. Weil, Gregor Probst, Friederike M. Graf · 2003
An intelligent electronic transmission control system using both fuzzy logic and conventional methods is presented. The controller is part of the drive train, so that special attention must be paid to the system's security. Two different methods for prioritizing the controller outputs are proposed, and it is shown how these methods can be realized within fuzzy control theory. Next, it is shown, in an application, how rules can be derived as a mixture of human expert knowledge and dynamic process models. The controller is tested in a simulation environment. The results are compared with those obtained by using conventional shift logic.>
