Abstract:
According to the AT minicar project of Changan Automobile CO.Ltd.,the system for simulating the dynamic driving mode of the powertrain with Automatic Transmission is established.The engine and hydraulic torque converter are tested,and the character diagrams are protracted.The two parameter shift rule and the driver fuzzy control module are established.On the basis of dynamical equation,the kinetic model of car is established.With the system,the dynamic and economical performances and ten-mode driving status are simulated.The simulation results show that the system can simulate the actual driving status well,the dynamic and economical performances of the minicar basically meet the technical requirements.The theoretic foundation is provided to the project.The foundation of cruise control is constituted.
