Title:
CONTROL DEVICE FOR VEHICULAR TRANSFER
Document Type and Number:
WIPO Patent Application WO/2020/235590
Kind Code:
A1
Abstract:
In the present invention, a transfer (13) that changes a distribution ratio of torque on wheels using an electric motor (43) is controlled by a TF-ECU (18). The TF-ECU (18) comprises: a drive circuit (200) that drives the electric motor (43); a current sensor (53) that detects the actual current of the electric motor (43); and a microcomputer (100) that calculates a target current (I*) corresponding to the desired distribution ratio of torque, that performs current feedback control in which an operation amount (D) of the electric motor (43) is calculated such that the actual current (Ia) reaches the target current (I*), and that outputs a drive signal based on the operation amount (D) to the drive circuit (200).
