  • Method of regulating supercharger boost pressure
    Patent number: 5186081
    Abstract: The torque output of a fluidic torque converter that is driven by a supercharged engine and whose output is coupled to the input of a hydraulic automatic transmission is determined and compared with a transmission input torque limit which is a function of the transmission gear. The boost pressure output of the engine supercharger is limited based on this comparison to closed loop limit the torque output of the torque converter at the transmission input torque limit.
