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.

Hybrid drive device

A hybrid drive device in which an input shaft is connected to an engine, an output shaft is connected to wheels, and a wheel drive motor is connected between the input shaft and the output shaft. In the hybrid device, a friction engagement element that is provided between the input shaft and the output shaft and of which transfer torque is controllable. A control device controls the friction engagement element. The control device reduces the transfer torque of the friction engagement element during engine starting in a predetermined low temperature environment or during travel on a bad road, compared to the transfer torque of the friction engagement element in an engaged state.

A hybrid driving apparatus includes an engine configured to output a rotation driving force to an output shaft; an input shaft configured to rotate in association with rotation of driving wheels of a vehicle; a clutch that is provided between the output shaft and the input shaft to disengageably connect the output shaft and the input shaft; a clutch actuator configured to operate the clutch; a motor generator configured to rotate in association with rotation of the input shaft; a rust formation determining unit configured to determine whether there is a possibility of a rust formation on the clutch; and a rust formation suppressing unit configured to operate the clutch actuator in a case where the rust formation determining unit determines that there is the possibility of the rust formation on the clutch.

Hybrid driving apparatus

A torque vibration absorbing device includes a clutch hub with a flange extending radially, a pair of intermediate plates disposed at both outsides of the flange so as to be rotatable relative to the flange, a disc plate and a sub-plate disposed at the outside of the intermediate plates so as to be rotatable relative to the flange and the intermediate plates, a plurality of connecting pins which connect the disc plate and the sub-plate, and a plurality of elastic members provided in series at the inside of the disc plate and the sub-plate through the intermediate plates, wherein at least one elastic member is maintained at a predetermined amount of compression when a torsional degree between the flange and each of the disc plate and the sub-plate is changed to be larger than the predetermined amount thereof and the other elastic members are continued to be compressed exceeding the predetermined amount of compression.
