Abstract

A control system for an electric vehicle configured to allow a driver to enjoy behaviors of conventional vehicles having an engine and a transmission more realistically, without impairing comfort and quietness of the electric vehicle. In a virtual AT mode, a target torque value of a motor with respect to a motor speed is changed stepwise in accordance with an operating range shifted automatically, and a simulated engine sound is emitted. The emission of the simulated engine sound is continued until the virtual AT mode is cancelled and a shift lever is moved to a drive position.
