PROBLEM TO BE SOLVED: To provide a driving force transmission control device and a driving force transmission device control method each of which enables error in driving force transmitted by a multiple disc clutch to be reduced by controlling an electric motor when malfunction which may cause the error occurs in a hydraulic circuit.;SOLUTION: A driving force transmission control device 1 includes: a multiple disc clutch 53; a piston 50 pressurizing the multiple disc clutch 53 by a pressure of a hydraulic fluid in a cylinder 220; a pump 82; an electric motor 81 for operating the pump 82; a flow channel constitution member guiding a part of the hydraulic fluid delivered from the pump 82 to the cylinder 220; and a control device 9 controlling the electric motor 81. The control device 9 has electric current command value calculation means 911 calculating an electric current command value, and correction means 912 calculating a correction electric current command value by correcting the electric current command value. The correction means 912 calculates a correction value according to difference between a reference value and a measurement value of the rotational speed or of the current of the electric motor 81 when the electric motor 81 is operated under a prescribed operation condition.;SELECTED DRAWING: Figure 8;COPYRIGHT: (C)2019,JPO&INPIT
