Claim 0:
1. A control method of generating a virtual sensation of gear shifting of an electric vehicle, comprising:
determining, by a controller, a basic torque command in real time based on vehicle driving information collected while the electric vehicle is being driven;
determining, by the controller, a virtual target gear shift stage based on the vehicle driving information collected from the vehicle;
determining, by the controller, a gear shift class from a virtual current gear shift stage and the determined virtual target gear shift stage and selecting a virtual gear shift intervention torque profile corresponding to the determined current gear shift class from among preset virtual gear shift intervention torque profiles for each gear shift class;
determining, by the controller, a virtual gear shift intervention torque for generating the virtual sensation of gear shifting in the real time according to the selected virtual gear shift intervention torque profile and generating a final motor torque command using the e determined basic torque command and the virtual gear shift intervention torque; and
adjusting, by the controller, an operation of a motor for driving the vehicle according to the generated final motor torque command;
wherein, in the determining of the basic torque command in real time, the basic torque command is calculated from a sum of a regenerating torque command, a coasting torque command, and a driving torque command; and
wherein, in the generating of the final motor torque command, when driving, the summed basic torque command is limited to a limit torque value for the driving direction, and
when coasting and regenerating, the summed basic torque command is limited to a limit torque value for the regenerative direction.
