    摘要: Disclosed are a hybrid electric vehicle, which is capable of controlling engine starting in consideration of entry into a specific area, and method of controlling the same. A method of controlling engine starting of a hybrid vehicle includes determining whether catalyst heating is necessary, determining whether a current location corresponds to a specific area associated with exhaust emissions, determining whether a first mode driving is possible, when it is determined that the current position corresponds to the specific area and the catalyst heating is necessary, and performing the first mode driving when the first mode driving is determined to be possible, or a second mode driving when the first mode driving is determined to be impossible. Here, the first mode driving is performed by using an electric motor, and the second mode driving is performed by using at least an engine.

    摘要: A transmission control method during regenerative braking of a hybrid vehicle is directed to providing a transmission control method during regenerative braking of a hybrid vehicle that is capable of accurately estimating the regenerative braking execution amount, by constantly controlling the transmission output torque, that is, the regenerative braking execution amount, until the transmission input speed reaches the speed corresponding to the target transmission stage, through the operating element torque and motor torque intervention control for transmission, when transitioning to the target transmission stage from the current transmission stage of the multistage automatic transmission of the hybrid vehicle, and is capable of accurately estimating the regenerative braking execution amount and simultaneously securing the braking linearity during transmission.
