A hybrid vehicle includes an electric motor, an engine including an exhaust gas purifying unit, and an engine clutch disposed between the electric motor and the engine. A method of controlling the hybrid vehicle includes determining a driving environment condition including a first condition related to at least a driving load when a request for operating the exhaust gas purifying unit is received, determining a state of the engine clutch and an operation condition of the exhaust gas purifying unit when the exhaust gas purifying means operates according to the result of determining the driving environment condition, and operating the exhaust gas purifying unit while maintaining the determined state of the engine clutch when the driving environment condition is satisfied.

A method for identifying a driving pattern for fuel economy improvement of a hybrid vehicle is provided. The method includes allocating priorities in accordance with influences exerted on fuel economy based on a heating load and an electric load. A current driving pattern is then selected in the order of a high heating load driving pattern, a high electric load driving pattern, an aggressive driving pattern, a high speed driving pattern, and a city driving pattern.

A motor speed control method and system for improving the performance of a running resistance evaluation of a hybrid electric vehicle are provided. The method includes determining whether a vehicle satisfies a running resistance evaluation start condition. When the vehicle satisfies the running resistance evaluation start condition, the speed of a motor is adjusted, which adjusts an input speed of a transmission to be equal to an output speed of the transmission. A speed adjustment of the motor is then completed using the speed of the motor and the output speed of the transmission.
