Abstract
A method of estimating transmission torque of a dry clutch, may include a) slowly releasing a dry clutch until a slip of the dry clutch occurs, b) acquiring and storing stroke of an actuator and torque of an engine at a starting time point at which the slip of the dry clutch occurs at step a), and c) determining the stroke of the actuator and the transmission torque of the dry clutch at the starting time point at which the slip of the dry clutch occurs, by using the stroke of the actuator and the torque of the engine stored at step b).
Claims6
A method of estimating transmission torque of a dry clutch in an automated manual transmission (ATM), comprising:
- a) slowly releasing, by the ATM, a dry clutch until a slip of the dry clutch occurs;
- b) acquiring and storing, by the ATM, stroke length of an actuator and torque of an engine at a starting time point at which the slip of the dry clutch occurs at step a);
- and
- c) determining, by the ATM, the stroke length of the actuator and the transmission torque of the dry clutch at the starting time point at which the slip of the dry clutch occurs, by using the stroke length of the actuator and the torque of the engine stored at step b).
