| description | The present invention generally pertains to motor vehicles. More particular, the present invention pertains to a method of controlling a transmission. More specifically, but without restriction to the particular embodiment and/or use which is shown and described for purposes of illustration, the present invention relates to a method for controlling a transmission having a dual clutch system during vehicle launch.
A method of controlling a dual clutch transmission of a motor vehicle, wherein the first clutch acts to transmit torque to the first driven gear, and the second clutch acts to transmit torque to the second driven gear. The steps involved in controlling the transmission include determining a predetermined first clutch slip value based on the perceived vehicle loading, initiating launch of the motor vehicle with both the first and the second clutch partially engaged, determining the vehicle inertia value based on the summation of instantaneous vehicle inertia values during vehicle launch, and controlling either the first or the second clutch to disengage when the predetermined first clutch slip value is reached. |
