    Abstract: A vehicle control method may include determining by a controller, a state of a brake pedal wherein a controller is configured to determine during performing an SSC control mode whether a brake pedal is in an ON state; determining, by the controller, overlap of control modes wherein when it is determined in the determining by a controller, a state of a brake pedal that the brake pedal is in the ON state, the controller is configured to determine whether conditions for performing an extended ISG control mode are satisfied; and converting, by the controller, a control mode wherein when it is determined in the determining, by the controller, overlap of control modes that the conditions for performing the extended ISG control mode are satisfied, the controller terminates the SSC control mode being performed and converts the current control mode to the extended ISG control mode.

    Abstract: A virtual gear shift control apparatus for an electric vehicle is disclosed. The apparatus includes a driving information detector that detect information indicating a vehicle driving state. The apparatus also includes a controller that generates a motor torque command for satisfying a driver's demand torque based on the vehicle driving information including the information detected by the driving information detector. The controller determines whether the vehicle driving state of the electric vehicle corresponds to a predetermined power-off condition, determines, in response to a determination that the vehicle driving state corresponds to the predetermined power-off condition, a coasting torque corresponding to a current virtual gear stage and a current virtual engine speed. The controller also generates a motor torque command using the determined coasting torque as a command value. The controller also controls a regenerative operation of a motor that drives the electric vehicle according to the generated motor torque command.
