Dual clutch transmission control method, dual clutch transmission, and vehicle mounted therewith

A dual clutch transmission which includes at least 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, and in which a set of odd-numbered gears and a set of even-numbered gears are arranged every one step for alternation respectively between the first and the second input shafts and an output shaft, and in a case of starting transmission of power from a power source to the output shaft, the transmission of the power is started by synchronously engaging a start gear being one of the gears for start to the second input shaft and connecting the second clutch to the second input shaft, comprising:

• the dual clutch transmission including a support gear and a control device, the support gear having a gear ratio smaller than that of the start gear by one speed or higher, and
• the control device including a control of, at the time of starting the transmission of the power from the power source to the output shaft, synchronously engaging the start gear to the second input shaft and synchronously engaging the support gear to the first input shaft, respectively, and a control of simultaneously connecting the first clutch partially to the first input shaft and the second clutch partially to the second input shaft, respectively.
