SMART SHIFT ASSISTANCE SYSTEM FOR MANUAL TRANSMISSION

WIPO Patent Application WO/2019/014876

A1

Systems, apparatuses, and methods disclosed provide for assisting gear shift for a manual transmission of a vehicle. An engine control unit (ECU) receives a gear shift request from a gear selector. The gear shift request requests shifting gear to a desired position. The ECU eliminates an engine torque to substantial zero and indicates the gear is ready to be moved to a neutral position. The ECU then determines whether the gear has been moved to the neutral position. In response to determining the gear has been moved to the neutral position, the ECU adjusts an engine speed to match a gear ratio corresponding to the desired position and a transmission output speed and indicates the gear is ready to be shifted to the desired position. The ECU then determines whether the gear has been shifted to the desired position. In response to determining that the gear has been shifted to the desired position, the ECU recovers the engine torque.
