Vehicle including electric motor and method of controlling brake lamp for the same

A vehicle comprising:

• an electric motor configured to provide regenerative braking force;
• and
• a controller;
• wherein the controller is configured to:
• determine whether gear shifting is required and whether there is a forward section with a slope that is greater than a preset threshold value when regenerative braking is performed through the electric motor without manipulation of an accelerator pedal or a brake pedal;
• delay the gear shifting until the gear shifting exceeds a gear-shifting limit when the gear shifting is required and when there is the forward section with the slope;
• calculate acceleration based on regenerative braking torque while the gear shifting is delayed;
• and
• control the brake lamp based on the calculated acceleration;
• wherein the controller is further configured to determine whether the gear-shifting limit is exceeded based on a vehicle speed, a gear ratio of a current gear stage, and a maximum number of revolutions per minute of a motor.
