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.
Claims20
A clutch control method for a hybrid vehicle with a dual-clutch transmission (DCT), comprising:
- checking, by a controller, whether a current shift range is a drive (D)-range;
- determining, by the controller, 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, reducing, by the controller, an operation current supplied to a clutch actuator of a clutch for transmitting power to a first gear to a regulation current;
- and
- setting, by the controller, the regulation current based on an operation of the vehicle by a driver when the vehicle is restarted after the operation current reduction.
A clutch control system for a hybrid vehicle with a dual-clutch transmission (DCT), comprising:
- a memory configured to store program instructions;
- and
- a processor configured to execute the program instructions, the program instructions when executed configured to:
- check whether a current shift range is a drive (D)-range;
- determine 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, reduce an operation current supplied to a clutch actuator of a clutch for transmitting power to a first gear to a regulation current;
- and
- set the regulation current based on an operation of the vehicle by a driver when the vehicle is restarted after the operation current reduction.
