Abstract
A method for preventing an incorrect learning of a clutch torque of a transmission of a vehicle may include a controller estimating an engine-based clutch torque estimated based on an engine torque; the controller estimating a wheel-based clutch torque estimated based on a driveshaft torsional torque; the controller determining a torque error, which is a difference between the engine-based clutch torque and the wheel-based clutch torque: the controller allowing a learning of the clutch torque when the torque error is equal to or less than a predetermined reference torque; and the controller prohibiting the learning of the clutch torque when the torque error is greater than the predetermined reference torque.
Claims13
A method for preventing an incorrect learning of a clutch torque of a transmission of a vehicle, the method comprising:
- estimating, by a controller, an engine-based clutch torque estimated based on an engine torque;
- estimating, by the controller, a wheel-based clutch torque estimated based on a driveshaft torsional torque;
- determining, by the controller, a torque error, which is a difference between the engine-based clutch torque and the wheel-based clutch torque;
- allowing, by the controller, a learning of the clutch torque when the torque error is equal to or less than a predetermined reference torque;
- and
- prohibiting, by the controller, the learning of the clutch torque when the torque error is greater than the predetermined reference torque.
