CONTROL METHOD FOR DUAL CLUTCH TRANSMISSION, DUAL CLUTCH TRANSMISSION, AND VEHICLE LOADED WITH SAME

摘要

Provided is a method of controlling for a dual clutch transmission, a dual clutch transmission, and a vehicle equipped with the same which prevent double engagement that may otherwise occur due to use of both clutches for reducing the load on one of the clutches on a start gear side to reduce the wear thereof and therefore make the clutch replacement interval longer, and which also allows torque from both clutches to be transmitted entirely to the start gear. There are a first input shaft 11 configured to be connected to a first clutch C1 and a second input shaft 12 configured to be connected to a second clutch C2. A set of odd-numbered gears G1, G3, and G5 and a set of even-numbered gears G2, G4, and G6 are arranged respectively across the first input shaft and second input shaft 11 and 12 and an output shaft 3. The gear G2 and the gear G1 are set as a start gear DG2 and a support gear SG1, respectively. A one-way clutch 30 is provided between the support gear SG1 and the first input shaft 11 and is configured to let the support gear SG1 freewheel when a vehicle is started by synchronously engaging the start gear DG2 and the support gear SG1 to the second input shaft 12 and the first input shaft 11, respectively, and simultaneously bringing each of the first clutch C1 and the second clutch C2 into a connected state. A third clutch 40 is further provided which is configured to connect the first input shaft 11 and the second input shaft 12 and rotate them together when the vehicle is started.
