Title:
Driving force transmission controller
Document Type and Number:
Japanese Patent JP6194666
Kind Code:
B2
Abstract:
A driving force transmission control system (1) includes: an electric motor (5); a multi-disc clutch (8); a cam mechanism (3) that converts rotation output from the electric motor (5) into cam thrust force that is axial force in the axial direction of the multi-disc clutch (8); a pressure-conversion mechanism (6) that converts reaction force against the cam thrust force into pressure of a fluid; a pressure sensor (10) that detects the pressure; and a control unit (12) that computes a command value of a current supplied to the electric motor (5). The control unit (12) stores the pressure of the fluid during disengagement of the multi-disc clutch (8), and computes the current command value based on the pressure of the fluid to which the reaction force against the cam thrust force has been applied, and the stored pressure of the fluid.
