  • Patent number: 11130496
    Abstract: A clutch control method for a hybrid vehicle with a DCT of the present invention is provided. The method includes checking whether a current shift range is a D-range and determining a gradient of a current driving road and driver's vehicle stop requirement. In response to determining that the current shift range is the D-range, the gradient of the road is not a gradient that requires uphill driving, and there is driver's vehicle stop requirement, a controller reduces an operation current supplied to a clutch actuator of a clutch for transmitting power to a first gear to a regulation current. The regulation current is set based on an operation of the vehicle by the driver when the vehicle is restarted after the current reduction.
