摘要:
A method of estimating transmission torque of a vehicle dry clutch may suitably estimate a variation in the characteristics of transmission torque relative to the actuator stroke of a dry clutch even during the driving of a vehicle, so that the dry clutch is more suitably controlled. In the method of estimating transmission torque of a dry clutch, a clutch is released so that a slip of the clutch occurs. If the slip of the clutch has occurred, the slip of the clutch is uniformly maintained. If the slip of the clutch is uniformly maintained, a relationship between a stroke of an actuator of the clutch and transmission torque of the clutch is determined from a relationship between the stroke of the actuator and torque of an engine in the uniformly maintained slip state.
摘要:
A method and an apparatus for controlling a clutch of a vehicle include determining whether a vehicle is moving under a condition in which a gearshift is coupled to the clutch. A clutch torque is learned in which the clutch is maintained in a micro-slip state by decreasing a target clutch torque for a corresponding gear level when it is determined that the vehicle is moving under the condition in which the gearshift is coupled to the clutch. Learning reliability is calculated by reflecting a difference between an engine torque and clutch torque. The clutch is maintained in the micro-slip state for the clutch torque learning or converting the clutch into a lock-up state, depending on a learning reliability level.

A method of correcting clutch characteristics of a vehicle may include determining whether or not a difference in temperature between a surface and a core of a driving clutch exceeds a reference value, and correcting a torque-stroke (T-S) curve if it is determined that the difference in temperature exceeds the reference value. The correcting of the T-S curve may include moving the T-S curve from a currently selected position in a direction in response to a rise in temperature.

A method of adjusting the transmission torque characteristics of a dry clutch may include carrying out adjustment based on learning using a T-S curve that indicates the relationship of the transmission torque to the actuator stroke of the dry clutch, a section of the T-S curve in which inclinations change discontinuously is removed, so that the controllability over the dry clutch is reliable and the feeling of shifting can be improved.

The present disclosure provides a driving control method for hybrid type vehicles with a DCT. The method includes: receiving the motor speed from a driving motor; when abnormality of the motor speed is detected, requesting driving of an engine and determining whether an engine clutch is engaged; if it is determined that the engine clutch is released, controlling a clutch of a current driving stage using a clutch torque higher than a transmission input torque; controlling the current driving stage to be a limp home driving stage set in advance to be in a limp home driven status.
