Virtual gearshift (VGS) introduces the method to generate engine vibration and gearshift feeling without an internal combustion engine and multi-speed transmission in order to fulfill the desire for sport and track driving. Such fun addition to EVs can grant the drivers unique and expanded driving experience. Instead of conducting an actual gearshift that involves physical change in the state of clutch components and engine speed, the virtual gearshift only creates the gearshift feeling for the driver. This task can be accomplished solely by the virtual transmission control unit (vTCU) controlling what are perceived by the driver: vehicle motion, sound effect, and cluster information – the three major factors through which the driver recognizes the vehicle behavior. The entire virtual function is applied to an actual electric vehicle, and is tested on the proving ground in an integrated manner.
