摘要： A control method includes an electronic waste gate actuator (EWGA) and a waste gate valve, connected to each other through a rod. The control method includes an operation condition determination step for determining whether an engine is in cold operation or hot operation by measuring engine soak time and initial coolant temperature when the engine starts and by comparing them with a predetermined reference soak time and reference coolant temperature. The control method also includes a cold control step for setting cold operation reference voltage, performing cold operation learning, and applying cold operation learning data to the cold operation reference voltage, when the engine is in cold operation. The control method further includes a hot control step for setting hot operation reference voltage, performing hot operation learning, and applying hot operation learning data to the hot operation reference voltage, when the engine is in hot operation.
