Title:

HYBRID DRIVE DEVICE

Document Type and Number:

WIPO Patent Application WO/2014/041992

Kind Code:

A1

Abstract:

Provided is a technique for accurately correcting clutch torque in a hybrid drive device having a clutch (20) which connects and disconnects the output shaft (EG-1) of an engine and the input shaft (51) of a planetary gear mechanism (10), and a motor generator (MG1) which rotates in conjunction with rotation of the input shaft (51). This hybrid drive device is provided with: a target control amount calculation unit which, on the basis of a clutch torque map which represents the relation between the clutch torque and the control amount corresponding to operation of an actuator (50) driving the clutch (20), calculates a target control amount of the actuator (50) corresponding to the target clutch torque; an estimated clutch torque calculation unit which, in a state in which the clutch (20) is asynchronous, calculates an estimated clutch torque on the basis of the torque which the first motor generator (MG1) generates and the rotational acceleration of the input shaft (51); and a correction unit which corrects the clutch torque map on the basis of the target clutch torque and the estimated clutch torque.
