Abstract
Some embodiments relate to determining an estimated torque output by a vehicular transmission. A first controller determines a target gear number and an actual gear number during shifting between the gears of the transmission, the target gear number being equal to a value of a gear number to which the transmission is shifting, the actual gear number being equal to a value of a gear number from which the transmission is shifting. A second controller compares the target gear number to the actual gear number and retrieves a blended gear number if the target gear number is greater than the actual gear number, determines an approximate value for a gear ratio that decreases in proportion to a rate of decrease in torque output by the transmission based on the blended gear number, and estimates a value of the torque output by the transmission based on the determined gear ratio.
