Abstract
Rev-matching techniques that do not require a gear position sensor or a clutch position sensor are provided for a manual transmission of a vehicle. The techniques include predicting an intent of a driver to shift gears of the manual transmission based on whether the vehicle is accelerating or decelerating; predicting a shift of the manual transmission from a current gear to a different target gear based on the predicted driver intent; and detecting a trigger condition indicative of the predicted shift of the manual transmission based on a position of a clutch pedal configured to control engagement/disengagement of a clutch of the manual transmission. In response to detecting the trigger condition, a torque request for the torque generating system is modified to obtain a modified torque request, and the torque generating system is controlled based on the modified torque request.
