CONTROL DEVICE OF AUTOMATIC CLUTCH FOR VEHICLE
Document Type and Number:
Japanese Patent JP2012052618
Kind Code:
A
Abstract:
To provide a control device of an automatic clutch for a vehicle that corrects a clamp point of the automatic clutch with accuracy, in the automatic clutch for the vehicle.
A correction amount of the clamp point "clamp" is changed in response to a temperature change direction of the automatic clutch 14, and thereby the clamp point "clamp" is corrected in the optimum correction amount according to a temperature change tendency (heating or cooling state) of the automatic clutch 14. Accordingly, as the clamp point "clamp" becomes more accurate comparing with a correction based on only a clutch temperature "thc" of the automatic clutch 14, the control accuracy of the automatic clutch 14 is improved further.
