Abstract: A method and associated computer-executable code for controlling an automotive powertrain featuring a manual transmission determines a current transmission output speed based at least in part on the vehicle speed achieved in response to a torque request signal; determines an effective transmission gear ratio based on the engine speed and the transmission output speed; and compares the effective transmission gear ratio to each of the predetermined transmission gear ratios. A transmission shift is deemed to be in progress when the effective transmission gear ratio is not within a predetermined tolerance of any of the predetermined transmission gear ratios. Relatively-aggressive smoothing of the torque request signal upon pedal tip-out is advantageously canceled when a shift is deemed to be in progress, thereby reducing the likelihood of unintended engine speed and/or transient flares when a declutching event follows shortly after the pedal tip-out.
