  • Teaching method of transmission control unit of vehicle
    Patent number: 8245908
    Abstract: A teaching method of a transmission control unit (TCU) allows one to transmit specific property data of a transmission manufactured in a transmission production line to a vehicle assembly line where the TCU and the transmission are assembled, and input the data to the TCU in a very inexpensive and simple fashion. The method also allows the TCU that controls a CVT to appropriately initialize kiss-point pressure of the CVT that uses a wet-type multi-disc clutch, instead of a torque converter, and is equipped with a solenoid valve directly controlling the wet-type multi-disc clutch, such that it makes it possible to allow the TCU to stably and appropriately control the CVT to be controlled, with the property data about the CVT which is restrictively transmitted.
