Abstract

A method of controlling a dual clutch transmission, a dual clutch transmission, and a vehicle equipped with the same which can reduce the load on a clutch on a start gear side to reduce the wear thereof and therefore make the clutch replacement interval longer. There are a first input shaft to be connected to a first clutch and a second input shaft to be connected to a second clutch. A set of odd-numbered gears and a set of even-numbered gears are arranged respectively across the first input shaft and second input shaft and an output shaft. When a vehicle starts, a start gear and a support gear are synchronously engaged to the second input shaft and the first input shaft, respectively, and simultaneously connecting the first clutch and the second clutch partially (half clutch state) to the first input shaft and the second input shaft, respectively, the support gear having a gear ratio smaller than that of the start gear by one speed or higher.
