1. An electric vehicle comprising a motor as a driving source, the electric vehicle comprising:
an accelerator configured to receive an acceleration request;
a pseudo shifter configured to be operated by a driver who drives the electric vehicle, and mimic a gear changing operation;
a pseudo clutch configured to be operated by the driver and mimic a clutch operation;
a detector configured to detect an operation mode performed on the accelerator by the driver, an operation mode performed on the pseudo shifter by the driver, an operation mode performed on the pseudo clutch by the driver, and a rotation speed of a driving wheel;
a reaction force generator configured to generate a reaction force in the pseudo shifter in response to the operation mode performed on the pseudo shifter by the driver; and
a controller configured to determine the reaction force to be generated in the pseudo shifter,
wherein the controller comprises:
at least one processor; and
at least one memory coupled to the at least one processor, and
wherein the at least one processor is configured to:
calculate a virtual differential rotation speed based on one or more of detection results obtained by the detector, the virtual differential rotation speed being based on at least a virtual engine rotation speed and the rotation speed of the driving wheel, the virtual engine rotation speed mimicking an engine rotation speed when the driving source is assumed as being an engine, and
determine the reaction force to be generated in the pseudo shifter based on at least the virtual differential rotation speed.
