Abstract: This study presents an overview of control logic development for automotive transmission in both electric and non-electric powertrain. The control of automotive power transmission determines the shift quality that is attaining smoother shifting, leading to better drivability which rather important. The steady upswing of electronic and embedded systems has supplanted mechanical controls. The transition of actuation technology from mechanical to electromechanical type also propels the development of electronic controls in the vehicle. The electronic transmission control unit (TCU) governing automation of gear-shifting process in the transmission system, betters the driving experience due to improved shifting quality. There has been a rising demand for automatic gear shifting owing to its potential for uninterrupted gear shifting or also called power shifting. Gear shifting strategy and control are central to quality shifting process. Hence this work presents state of the art on controls for gear shifting and identifies the scope of further research.

Keywords: automotive transmission; transmission control; gear shifting; shift quality; virtual electronic controller simulator; electric powertrain; non-electric powertrain.
