Abstract
On the basis of describing the principle of adjusting main pressure and establishing the model of clutch engaging process for the electronic automatic transmission, the different torques transfered by the transmission and the influence of main pressure on shifting process under different gears were analyzed, and the necessary of adjusting main pressure was proposed. The principle and the method of adjusting main pressure were obtained by analyzing the electro-hydraulic control system of HD4070PR automatic transmission. The adjusting technique of main pressure was verified by an experiment, and the improvement of shifting equality was analyzed by the experimented data.
