Abstract
A control method of a clutch for a vehicle may include determining whether or not learning of clutch characteristics is possible; learning the clutch characteristics when the learning of the clutch characteristics is possible; determining a clutch torque for controlling the clutch in consideration of a change amount in the clutch torque before and after the learning and controlling the clutch by the determined clutch torque; and determining whether or not it is difficult to continue to learn the clutch characteristics.
Claims20
A method of controlling a clutch for a vehicle, the method comprising:
- determining, by a controller, when learning of clutch characteristics is possible;
- learning, by the controller, the clutch characteristics upon determining that the learning of the clutch characteristics is possible;
- determining, by the controller, a clutch torque for controlling the clutch in consideration of a change amount in the clutch torque before and after the learning and controlling the clutch by the determined clutch torque;
- and
- determining, by the controller, when continuously learning the clutch characteristics is not possible.
A dual clutch transmission comprising:
- a first input shaft selectively connectable to an engine by a first clutch;
- a second input shaft selectively connectable to the engine by a second clutch;
- a plurality of gears mounted on the first input shaft and the second input shaft;
- a clutch actuator engaged to the first and second clutches and configured of controlling the first and second clutches;
- a gear actuator engaged to the plurality of gears and configured of changing a gear engagement between the plurality of gears for gear shifting;
- a controller connected to the clutch actuator and the gear actuator and including a processor and a non-transitory storage medium on which a program is recorded, the program executed by the processor and configured of performing:
- determining when learning of clutch characteristics of at least one of the first and second clutches is possible;
- learning the clutch characteristics upon determining that the learning of the clutch characteristics is possible;
- determining a clutch torque for controlling the clutch actuator in consideration of a change amount in the clutch torque before and after the learning and controlling the at least one of the first and second clutches by the determined clutch torque;
- and
- determining when continuously learning the clutch characteristics is not possible.
