ABSTRACT:
An adaptive control system/method for an at least partially automated vehicular mechanical transmission system (10) is provided for determining the current value of a control parameter (T.sub.FW) indicative of engine flywheel torque. Engine flywheel torque (T.sub.FW) is determined as a function of the expression gross engine torque (T.sub.EG) is equal to the sum of flywheel torque (T.sub.FW), base engine friction torque (T.sub.BEF), acceleration torque (T.sub.ACCEL) and accessory torque (T.sub.ACCES). Accessory torque (T.sub.ACCES) is determined, when the vehicle is in motion, as a function of engine deceleration rate (dES/dt rate). Flywheel torque (T.sub.FW), or drivewheel torque (T.sub.DW) determined as a function of flywheel torque (T.sub.FW) and drivetrain parameters such as engaged gear ratio (GR), is utilized as a control parameter for controlling shifting of the transmission system.
