Control system for electric vehicle

A control system for an electric vehicle that controls a motor serving as a prime mover based on a target torque value set in accordance with a required drive force, comprising:

• a sound creator that creates a simulated engine sound in accordance with a travelling condition of the electric vehicle;
• a controller that controls an output torque of the motor based on the target torque value;
• and
• a shifting device that is operated manually by a driver to
• select an operating mode of the electric vehicle from a first mode, a second mode, a third mode, and a fourth mode, and
• select an operating range of the electric vehicle from a plurality of ranges in which torque characteristics with respect to a speed of the motor differ from one another, in a situation where the third mode or the fourth mode is selected,
• wherein the first mode corresponds to a drive mode in which the electric vehicle is propelled forward,
• the second mode includes a reverse mode in which the electric vehicle is reversed, a parking mode in which the electric vehicle is parked, and a neutral mode in which a torque transmission between the motor and a pair of drive wheels is interrupted,
• the third mode is shifted from the first mode, and in the third mode, the target torque value of the motor with respect to a speed of the motor varies stepwise in accordance with the operating range selected by operating the shifting device and the simulated engine sound is emitted by the sound creator,
• the fourth mode is shifted from the first mode or the third mode, and in the fourth mode, the target torque value of the motor also varies stepwise in accordance with the operating range selected by operating the shifting device and the emission of the simulated engine sound is maintained, and
• the controller is configured to
• control the output torque of the motor based on the target torque value set in accordance with the operating mode and the operating range selected by operating the shifting device,
• cancel the third mode from being selected when the operating mode is shifted from the third mode to the first mode or the fourth mode, and
• cancel the fourth mode from being shifted from the third mode when the operating mode is shifted from the fourth mode to the third mode.
