Abstract
Disclosed are a method and an apparatus for detecting a touch point of a clutch and the method includes: maintaining a touch point of the clutch; correcting a setting value for determining a lowest value by calculating drag torque using a speed and an acceleration of a input shaft to change a detection range of the touch point; setting the lowest value of the speed of the input shaft within the changed detection range of the touch point to a reference value of the input shaft after actuating the clutch; releasing the clutch when the speed of the input shaft is more than a value acquired by adding the reference value of the input shaft and the corrected setting value for determining the lowest value; and updating the touch point as a clutch position matched to the reference value.
Claims14
A method for detecting a touch point of a clutch, the method comprising:
- calculating drag torque using a speed and an acceleration of an input shaft to change a detection range of the touch point;
- determining a lowest value of the speed of the input shaft within the changed detection range of the touch point;
- setting the lowest value to a reference value of the input shaft;
- and
- updating the touch point as a clutch position matched to the reference value.
An apparatus for detecting a touch point of a clutch, the apparatus comprising:
- a engine speed sensor configured to sense a speed and an acceleration of an input shaft;
- and
- a clutch control module configured to:
- calculate drag torque using a speed and an acceleration of an input shaft to change a detection range of the touch point;
- determine a lowest value of the speed of the input shaft within the changed detection range of the touch point;
- set the lowest value to a reference value of the input shaft;
- and
- update the touch point as a clutch position matched to the reference value.
