    摘要: A line pressure control method for a dual-clutch transmission (DCT), may include a hydraulic-pressure-decreasing operation of interrupting, by a controller, the supply of current to an electric oil pump and estimating a decrease in a line pressure using a line pressure model based on a pressure accumulator mounted in a hydraulic pressure line, a pump-driving operation of, when the estimated line pressure is equal to or less than a predetermined lower-limit value, driving, by the controller, the electric oil pump, and a hydraulic-pressure-increasing operation of determining, by the controller, the line pressure based on the current supplied to the electric oil pump and to determine whether the determined line pressure is equal to or greater than a predetermined upper-limit value.

    摘要: An acceleration control method for a dual clutch transmission (DCT) vehicle, may include determining whether an engine speed is lower than a desired shift stage input shaft speed by a controller when a driver's demand for acceleration is verified, determining whether an engine speed increased by the demand for acceleration is equal to or greater than the desired shift stage input shaft speed by the controller, feedback-controlling an engagement-side clutch to reduce a slip caused by a difference between the engine speed and the desired shift stage input shaft speed while maintaining an engine torque by the controller when the engine speed is verified to be equal to or greater than the desired shift stage input shaft speed, and completing control by verifying whether synchronization of the engine speed with the desired shift stage input shaft speed is stabilized.

    摘要: The present disclosure provides a clutch control method, including: a variation setting step of setting, by a controller, a current torque variation depending on a difference between a just previous clutch control torque and a clutch target torque; a limit determining step of determining whether a jerk of a clutch control torque need not be limited when the clutch control torque is reduced and then is increased or when the clutch control torque is continuously reduced by using the current torque variation and a just previous torque variation; a direction setting step and a limit setting step to determine a final torque variation based on the outcome of the limit determining step; and a control torque calculating step of calculating the clutch control torque to control a clutch.

    摘要: Disclosed are dry clutch control method and apparatus for a vehicle. The method may include a reference speed generating step of generating a virtual target input shaft speed from a wheel speed, a vibration recognizing step of detecting a vibration component based on a difference between an actually measured input shaft speed and the virtual target input shaft speed, and a control input step of additionally applying an anti judder control input to a clutch control torque controlling a dry clutch connected to an input shaft. The anti judder control input may be applied to the vibration component recognized in the vibration recognizing step in a form of being continuously damped starting from an impulsive control input.
