AUTOMATIC CLUTCH CONTROL DEVICE OF VEHICLE
Document Type and Number:
Japanese Patent JP2019044934
Kind Code:
A
Abstract:
To provide an automatic clutch control device of a vehicle for suppressing the occurrence of a clutch slide based on a rise of a temperature of an automatic clutch by performing an automatic semi-clutch operation for raising friction torque.SOLUTION: An automatic clutch control device 100 comprises a clutch control part 116 for increasing a spring load F of a diaphragm spring 32 for pressing a clutch disc 26 of an automatic clutch 14 when an automatic clutch temperature determination part 106 determines that a temperature Tc of the clutch disc 26 is equal to or higher than a prescribed temperature To, and also when a clutch slide determination part 108 determines that a clutch slide occurs in the automatic clutch 14 at an operation by a driver for bringing the automatic clutch 14 to a semi-clutch. By this constitution, the friction torque Tf of the automatic clutch 14 can be set larger than the engine torque Te of an engine 12 without limiting the transmission torque of the automatic clutch 14.SELECTED DRAWING: Figure 5
