CONVERTERLESS TRANSMISSION SHIFT CONTROL SYSTEM
摘要:
A converterless, multiple-ratio transmission and shift control method wherein smoothness of power-on upshifts and downshifts and power-off upshifts and downshifts is achieved by closed loop control of slip speed and friction element actuating pressure for an oncoming friction element, the data used during the closed loop control including speed sensor information for multiple friction elements during upshift and downshifts events.
