METHOD OF ESTIMATING VEHICLE DECELERATION DURING A TRANSMISSION GEAR SHIFT

摘要

A method for estimating deceleration of a wheeled vehicle during a transmission gear shift. A first input signal indicative of an engine torque and a second signal indicative of an input shaft rotational speed are used to predict the expected vehicle deceleration during a transmission ratio shift to a target gear ratio. An expected vehicle deceleration value is outputted to a shift decision control unit for implementing a transmission gear shift.
