Abstract
A method/system for controlling an automated transmission is provided wherein upon assembly of a vehicle, the intercept (A) and slope (B) values defining the presumed linear relationship between engine deceleration rate and engine accessory torque (dES/dt rate=A+(B * T.sub.ACCES)) and/or the value of engine rotational moment-of-inertia (I) for that particular vehicle are determined and memorized. Thereafter, the transmission is controlled as a function of these determined values.
