【Abstract】 Intelligent shift is a developing trend of the vehicle automatic transmission.In this paper,the prob- lem that how to realize intelligent control on the power shifting transmission of construction vehicle is studied with the control aim of the optimal driving.ZL50 wheel loader equipped with 4D180 hydraulic torque-con- verter is taken as object and the simulative model of powertrain and frame of construction vehicle are set up. On this base,intelligent control system of automatic shifting-selection based on CNN(chaotic neural network) for construction vehicle is designed.And a series of simulation studies are carried out by means of Matlab.The results of simulation show that the structure and algorithm of intelligent control system put forward in this pa- per is feasible and can realize automatic transmission of construction vehicle.更多还原
