  • Hybrid drive device
    Patent number: 9434377
    Abstract: 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.
