Abstract
A method predicts transfer torque of a dry clutch in a vehicle, in which a characteristic of transfer torque of the dry clutch caused by a stroke of a clutch actuator is accurately detected in a process of detecting a characteristic of a transmission when the vehicle is finished in an assembly line, and is applied to the control of the dry clutch using the clutch actuator, thereby previously preventing a phenomenon in which an excessive slip and an impact occur at the dry clutch and thus improving shift performance, for instance, securing durability of the dry clutch, or obtaining smooth shift feeling.
Claims6
A method of predicting transfer torque of a dry clutch in a vehicle, comprising:
- a first preparing process (S10) of operating a brake after an engine is started;
- a first driving process (S20) of driving an actuator to engage a clutch that has been disengaged;
- and
- a first predicting process (S30) of measuring a stroke of the actuator and a resulting engine torque during performing of the first driving process (S20) and storing a measured torque as clutch transfer torque based on the stroke of the actuator.
