20150134173 | HYBRID VEHICLE AND CONTROL METHOD FOR THE SAME - A control method of a hybrid vehicle is provided and includes determining whether a current vehicle driving mode is an EV mode, whether a current vehicle driving state satisfies a kick-down shift condition, and whether the current vehicle driving state satisfies a driving mode conversion condition for conversion into an HEV mode. The engine is started when the kick-down shift and the driving mode conversion conditions are satisfied. A current motor speed and discharging power of the battery are measured. The measured motor speed and predetermined motor reference speed are compared based on discharging power of the battery. A transmission input shaft target speed for the kick-down shift is calculated and compared to a predetermined transmission input shaft target reference speed based on discharging power of the battery. A control order is determined based on the comparisons and the kick-down shift and the engagement of the engine clutch are performed. | 05-14-2015 |
