Abstract
A clutch control method for a hybrid vehicle with a DCT is provided. The method includes determining an energy-saving possible period based on a selection state of shifting ranges, operation states of an accelerator pedal and a brake pedal, and the gradient of a road on which the vehicle is driven. An operation current is set for maintaining a clutch, which is configured to engage the first gear, engaged as 0 A in response to determining that a current state of the vehicle is in the energy-saving possible period.
Claims14
A clutch control method for a hybrid vehicle with a dual clutch transmission (DCT), comprising:
- detecting, by a controller, whether a current shifting range is a drive (D)-range;
- detecting, by the controller, a gradient of a road on which the vehicle is driven and a driver's stop requirement;
- and
- stopping, by the controller, an operation current that is supplied to a clutch actuator of a clutch that transmits power to a first gear in response to determining that a current shifting range is the D-range, that the gradient of the road does not require uphill driving, and detecting a driver's stop requirement.
A clutch control method for a hybrid vehicle with a dual clutch transmission (DCT), comprising:
- detecting, by a controller, an energy-saving possible period based on a selection state of shifting ranges, operation states of an accelerator pedal and a brake pedal, and a gradient of a road;
- and
- setting, by the controller, an operation current for maintaining a clutch, which is configured to engage a first gear, as zero amperes in response to determining that a current state of the vehicle is in the energy-saving possible period.
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:
- detect whether a current shifting range is a drive (D)-range;
- detect a gradient of a road on which the vehicle is driven and a driver's stop requirement;
- and
- stop an operation current that is supplied to a clutch actuator of a clutch that transmits power to a first gear in response to determining that a current shifting range is the D-range, that the gradient of the road does not require uphill driving, and detecting a driver's stop requirement.
