METHOD AND APPARATUS FOR LEARNING KISS POINT OF TRANSMISSION HAVING DUAL CLUTCH

摘要

The present invention discloses a kiss point learning apparatus and method for a dual clutch transmission vehicle. According to the present invention, the amount of change in the no-load speed when the non-drive clutch other than the clutch being driven among the dual clutches is not engaged and the amount of rotational variation of the driving clutch in the state where the non-drive clutch is engaged with the pre-stored kiss point are derived. If the derived rotation variation of the drive shaft clutch is greater than or equal to a predetermined criterion, the kiss point is trained based on the change of the load speed in the state directly connected to the kiss point, which is lowered to a predetermined value. By updating the pre-stored kiss point with data values, it is possible to accurately derive the kiss point in the dual clutch transmission vehicle, and to learn the kiss point even when the rotational variation of the driving clutch is greater than or equal to the reference threshold, thereby changing the driver's shift. Responsiveness to demand It obtained the effect capable of fundamentally improving the safety of the vehicle.
