Abstract: A method and an apparatus for controlling a hybrid electric vehicle are provided. The apparatus includes a navigation device that provides information regarding a gradient, a speed limit, and a traffic speed of a road. An accelerator pedal position detector detects a position of an accelerator pedal and a brake pedal position detector detects a position of a brake pedal. A vehicle speed detector detects a vehicle speed, a state of charge (SOC) detector detects an SOC of a battery, and a gear stage detector detects a gear stage that is currently engaged. A controller operates the hybrid vehicle based on signals of the navigation device, the accelerator pedal position detector, the brake pedal position detector, the vehicle speed detector, the SOC detector, and the gear stage detector.

Abstract: A hybrid vehicle is provided that includes a battery, a motor that is configured to generate a driving torque using the battery, and an engine that is configured to charge the battery or generate a driving torque together with the motor. A driving controller operates the motor and the engine and an air conditioning controller executes a heat function by a heat of an engine coolant and transmits an engine-drive-requiring signal to the driving controller to heat the engine coolant. When a first condition that a temperature of the engine coolant is greater than a first temperature and a second condition that a driving torque generated by the motor is sufficient to move the hybrid vehicle are satisfied, the engine operation is stopped by a time that a driving torque generated by the engine is required to move the hybrid vehicle regardless of receiving the engine-drive-requiring signal.
