METHOD AND APPARATUS FOR REGULATING SUPERCHARGER BOOST PRESSURE

摘要

The torque output of a fluidic torque converter (12) that is driven by a supercharged engine (10,24) and whose output is coupled to the input of a hydraulic automatic transmission (14) is determined and compared with a transmission input torque limit (MXTQ) which is a function of the transmission gear. The boost pressure output of the engine supercharger (24) is limited on the basis of this comparison to close loop limit the torque output of the torque converter (12) to the transmission input torque limit (MXTQ).
