Abstract:
1. A method of controlling a dual clutch transmission including a first input shaft to be connected to a first clutch, a second input shaft to be connected to a second clutch, a set of even-numbered gears arranged on the first input shaft, a set of odd-numbered gears arranged on the second input shaft, and an output shaft, comprising: providing, as a start gear, one gear from one of the set of odd-numbered gears or the set of even-numbered gears; providing, as a support gear, another gear of the other of the set of odd numbered gears or the set of even-numbered gears with a gear ratio different from that of the start gear; starting transmission of power from a power source to the output shaft by synchronously engaging the start gear to the second input shaft and synchronously engaging the support gear to the first input shaft, and simultaneously connecting the first clutch and the second clutch partially to the first input shaft and the second input shaft, respectively; and disconnecting the first clutch from the first input shaft and then connecting the second clutch to the second input shaft, when a difference between a rotational speed inputted to the second clutch and a rotational speed outputted from the second clutch falls below a predetermined threshold.
