Method of eliminating torque interruption during mode shift
摘要:
In a multiple mode continuously variable transmission having a variator, a planetary gear assembly, a low mode brake that grounds a first component of the planetary gear assembly to provide lower operating speeds and a high mode brake that grounds a second component of the planetary gear assembly to provide higher operating speeds, the method of providing a mode upshift comprising the steps of adjusting the ratio of the variator from a low ratio to a high ratio, releasing the low mode brake while simultaneously engaging the high mode brake during a torque phase of the shift and reducing the variator ratio from a high ratio to a low ratio during the inertia phase of the shift, thereby eliminating torque interruption and providing a constant torque output.
