Fuzzy Neural Network Control in Automatic Transmission of Construction Vehicle

The control of off-line fuzzy neural network can realize the shift of multi-parameter automatic transmission in construction vehicles. The method is based on fuzzy look-up table database. The gear shifting dynamically acts according to the shift database. The database was established by training the fuzzy neural network and was save in advance. The shift schedule table is saved in the three-dimensional and extensible spatial storage structure that can realize the multi-parameter fuzzy logic rule and quick finding of shift schedule. It copes with the real-time change of vehicle's running parameters and meet the requirement of intelligent control. The fuzzy neural network adopts error back-propagation algorithm.
