This paper describes the process of developing shift mechanism controller for use in dual clutch transmissions. The shift mechanism is characterized by one degree of freedom(single motor) with circular cam, whereas conventional shift mechanisms use dual motors for shift and select motion. We developed dynamic models of shift mechanism with one degree of freedom. And we developed controllers and motor drivers for shift mechanism. Through numerous experiments, we realize shift time below 0.2sec with Luk type synchronizer. And shift time about 0.355sec is realized for skip shift. the system will be combined with dual clutch controller, and commercialization process is in progress.
