    摘要: An apparatus and a method are provided for learning a touch point of an engine clutch of a hybrid electric vehicle that learns the touch point of the engine clutch based on a change of an engine torque while the hybrid electric vehicle is running The method includes determining whether an engine clutch coupling after shifting is required and whether a learning condition based on a running state of the hybrid electric vehicle is satisfied when the engine clutch coupling after shifting is required. A coupling pressure of the engine clutch is increased when the learning condition is satisfied and a changing amount of an engine torque based on the increased coupling pressure of the engine clutch is compared with a predetermined value. The touch point of the engine clutch is learned when the changing amount of the engine torque is greater than or equal to the predetermined value.

    摘要: A method of adjusting clutch characteristics of a Double Clutch Transmission (DCT) vehicle may include determining whether gear shifting has been initiated, updating a T-S curve of a release-side clutch by a transmission torque that is determined using an equation of motion of an engine and a clutch, when a condition in which a difference between an engine speed and a speed of a release-side input shaft is satisfied to be above a first predetermined reference value during a first reference period of time when the gear shifting is determined to have been initiated, and when a torque handover has not been initiated, updating the T-S curve of a connection-side clutch by the transmission torque that has been determined using the equation of motion during a period of time from completion of torque handover to completion of the shifting of gears.

    摘要: A vehicle includes an engine, an engine control module (ECM), and a dual clutch transmission (DCT) assembly. The DCT assembly has first and second input clutches, first and second gear sets selectively connected to the engine via the respective first and second input clutches, and a transmission control module (TCM). In executing a launch control method, the TCM receives a launch request, receives an actual engine torque, and determines the inertia and acceleration of the engine. The TCM then calculates a clutch torque for the particular input clutch used for vehicle launch as a function of the actual engine torque and the product of the inertia and the acceleration, compares the calculated clutch torque to the commanded clutch torque, modifies a torque-to-position (TTP) table depending on the comparison result, and transmits a clutch position signal to the designated input clutch to command an apply position extracted from the TTP table.
