A control device that includes an electronic control unit that is configured to: detect an actual current value flowing through the solenoid valve; receive a current command value and the actual current value detected and generate a primary command voltage value while feeding back the current command value on the basis of the actual current value; calculate a dither command voltage value to cause a periodic voltage oscillation; filter the actual current value detected to remove a frequency corresponding to a period of the dither command voltage value and output the filtered actual current value; generate a secondary command voltage value by superimposing the dither command voltage value generated on the primary command voltage value generated; convert the secondary command voltage value generated into a PWM signal; and generate, on the basis of the PWM signal generated, an application voltage to be applied to the solenoid valve.

Control device

A hybrid drive device has a clutch connecting and disconnecting an output shaft and an input shaft, a first motor generator that rotates in conjunction with the rotation of the input shaft, an allowable clutch heat generation amount calculation portion that calculates the allowable clutch heat generation amount, an allowable differential clutch rotation speed calculation portion which calculates the allowable differential clutch rotation speed for when engagement starts, on the basis of the allowable clutch heat generation amount, and a motor generator rotation control portion that controls the rotation speed of the first motor generator such that the differential clutch rotation speed when engagement starts and during engagement is no more than the allowable differential clutch rotation speed when engagement starts.
