Control system for electric vehicle

A control system for an electric vehicle having a rotary machine that delivers a torque to a wheel and a brake device that applies a brake torque to the wheel, but without having an engine, a transmission connected to the engine, and a clutch device that selectively interrupt torque transmission between the engine and the wheel, comprising:

• an operating device of an accelerator that is manipulated by a driver to accelerate and decelerate the electric vehicle;
• an operating device of a shifting device that is manipulated by the driver to imitate an operation of a manual transmission of a conventional vehicle having the manual transmission;
• a virtual torque transmitting capacity changing device that is manipulated to imitate an operation of a clutch of the conventional vehicle;
• an operating device of the brake device that is manipulated by the driver to control the brake torque established by the brake device;
• and
• a controller that controls the brake device,
• wherein the controller comprises a virtual engine speed calculator that calculates a virtual engine speed as a speed of an engine of the conventional vehicle in an actual running condition of the electric vehicle based on positions of the operating device of the accelerator and the virtual torque transmitting capacity changing device, and
• the controller is configured to
• execute an engine stall control to stop a rotation and a torque generation of the rotary machine, when the virtual engine speed calculated by the virtual engine speed calculator falls below a first predetermined speed, and
• terminate the engine stall control when the operating device of the brake device and the virtual torque transmitting capacity changing device are operated.
