Automatic transmission shift control based on transmission input shaft torque signal |
摘要 |
A system and method for minimizing torque disturbances during a shift event for an automatic transmission control actual transmission input shaft torque using a transmission input shaft signal produced by an input shaft torque sensor. The torque sensor provides a signal to a controller that monitors the measured transmission input torque. The torque sensor may be implemented by a strain gauge, a piezoelectric load cell, or a magneto-elastic torque sensor. The system may include a vehicle powertrain having an engine, a transmission coupled to the engine via a torque converter, an input torque sensor coupled to the input shaft of the transmission and a controller configured to control engine torque to cause the measured transmission input shaft torque to achieve a target transmission input shaft torque during the shift event. |
