TOUCH POINT CORRECTION METHOD FOR DOUBLE CLUTCH TRANSMISSION

摘要

A touch point correction method includes determining respective temperatures of a first pressure plate, a second pressure plate, and a center plate and measuring an average temperature of the determined temperatures, determining rotational inertia based on the measured average temperature, determining a touch point correction amount based on the rotational inertia and engine speed of a vehicle, and correcting a touch point of a relevant clutch using the determined touch point correction amount.

主权项

1. A touch point correction method for a Dual Clutch Transmission (DCT), comprising:
a) determining, by a controller, respective temperatures of a first pressure plate, a second pressure plate, and a center plate and measuring an average temperature of the determined temperatures; b) determining, by the controller, rotational inertia based on the average temperature measured at the a); c) determining, by the controller, a touch point correction amount based on the rotational inertia determined at the b) and engine speed of a vehicle; and d) correcting, by the controller, a touch point of a relevant clutch using the touch point correction amount determined at the c).
