The controller performs an inertia phase in which the coupling-side clutch torque is gradually increased while tracing an engine torque such that an engine speed is synchronized with a coupling-side clutch speed. The controller completes speed change through gradual decrease of the coupling-side clutch torque.Type: GrantFiled: March 30, 2020Date of Patent: March 22, 2022Assignees: Hyundai Motor Company, Kia Motors CornorationInventor: Sung Hyun Cho
