Title:

CLUTCH CONTROL METHOD

Document Type and Number:

Japanese Patent JP2016125649

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a clutch control method which can shorten a gear change time while alleviating a gear change shock and judder resulting from the abrupt connection of a clutch.SOLUTION: A clutch control method decides a first clutch indicator current Inecessary for obtaining a change rate of a target inter-input/output shaft rotation number difference, records a first inter-input/output shaft rotation number difference Vat a time point at which a clutch is abruptly connected while applying the first clutch indicator current Iduring a gear change, decides a maximum second clutch indicator current Iat which a variation of clutch transmission torque during the gear change reaches an allowable threshold or lower, records a second inter-input/output shaft rotation number difference Vat a time point at which the clutch is abruptly connected while applying the second clutch indicator current Iduring the gear change, decides a relationship between the clutch indicator current and the inter-input/output shaft rotation difference on the basis of the first clutch indicator current I, the first inter-input/output shaft rotation number difference V, the second clutch indicator current I, and the second inter-input/output shaft rotation number difference V, and sequentially decides a clutch indicator current during a succeeding gear change on the basis of the decision of the relationship.SELECTED DRAWING: Figure 1
