Abstract
A method of 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 configured to be connected to a first clutch and a second input shaft configured 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, an absorbed energy Eabs by the second clutch is calculated while a start gear is partially connected to the second input shaft. The first clutch is partially connected (half clutch state) to the first input shaft, to which a support gear is synchronously engaged, when the absorbed energy exceeds a set value which is a predetermined threshold, the support gear having a gear ratio greater than that of the start gear by one speed or higher.
