Vehicle control method

A vehicle comprising:

• an engine;
• an accelerator pedal;
• a brake pedal;
• and
• a controller electrically-engaged to the engine, the brake pedal and the accelerator pedal, wherein the controller is configured of:
• determining a state of the brake pedal, in which the controller is configured to determine, during performing a start-stop coasting (SSC) control mode, when the brake pedal is in an ON state;
• determining overlap of the SSC control mode and an extended idle stop and go (ISG) control mode, in which upon determining that the state of the brake pedal is in the ON state, the controller is configured to determine when conditions for performing the extended idle stop and go (ISG) control mode are satisfied;
• and
• converting a current control mode of the vehicle, in which upon determining that the conditions for performing the extended ISG control mode are satisfied, the controller is configured to terminate the SSC control mode and convert the current control mode to the extended ISG control mode,
• wherein upon determining that the conditions for performing the extended ISG control mode are not satisfied, the controller is configured to determine when conditions for releasing the SSC control mode other than the state of the brake pedal are satisfied and, when the conditions for releasing the SSC control mode is determined to be satisfied, the controller is configured to releases the SSC control mode.
