Abstract

This paper presents an adaptive fuzzy shift strategy of vehicle automatic shift. The shift strategy introduces throttle change as an adjustment parameter on the basis of the basic fuzzy shift strategy. It can adjust shift point according to the change of vehicle operation state and work environment. The results of simulation and test show that the adaptive fuzzy shift strategy can shorten the time of torque converter run to the low efficiency section, improve the efficiency of hydrodynamic-mechanical transmission system, and realize the optimal gear position of a transmission box. It is effective for intelligent control on automatic shift of construction vehicles
