Abstract
The present invention provides a method for searching a touch point of a clutch in a dual clutch transmission, including: (a) a step of checking whether a touch point searching condition for a non-driving clutch and a driving clutch is met or not; (b) when the search condition of the step (a) is met, a step of detecting a searching point at which an absolute value of a difference between an acceleration value of an engine and an acceleration value of the driving clutch is larger than a threshold value after applying a position value of the non-driving clutch to the engine; and (c) a step of determining a position of the non-driving clutch corresponding to the searching point as the touch point.
Claims4
A method for searching a touch point of a clutch in a dual clutch transmission, comprising:
- (a) a step of checking, by a controller, whether a touch point searching condition for a non-driving clutch and a driving clutch is met;
- (b) when the searching condition of the step (a) is met, a step of detecting, by the controller, a searching point at which an absolute value of a difference between an acceleration value of an engine and an acceleration value of the driving clutch is larger than a threshold value after applying a torque of the non-driving clutch to the engine;
- (c) a step of determining, by the controller, a position of the non-driving clutch corresponding to the searching point as the touch point;
- and
- (d) engaging, by the controller, the driving clutch and the non-driving clutch according to the detected position of the non-driving clutch.
