Abstract
It is provided a control device of a hybrid type vehicle power transmission device having a prime mover and an electric motor each coupled to a drive shaft in a power transmittable manner, including: a slow change processing means, when any of a torque of the drive shaft, a torque of the prime mover, and a torque of the electric motor changes and passes through zero, slowly changing the torque at a change rate set in advance for suppressing gear rattling noise; and a torque compensating means, if the slow change processing means slowly changes the torque of one of the prime mover and the electric motor, compensating a shortage of the torque of the drive shaft occurring due to the slow change with the other torque not slowly changed.

A control device of a hybrid type vehicle power transmission device having a prime mover and an electric motor each coupled to a drive shaft in a power transmittable manner, comprising:
- a slow change processing means, when any of a torque of the drive shaft, a torque of the prime mover, and a torque of the electric motor changes and passes through zero, slowly changing the torque at a change rate set in advance for suppressing gear rattling noise;
- and
- a torque compensating means, if the slow change processing means slowly changes the torque of one of the prime mover and the electric motor, compensating a shortage of the torque of the drive shaft occurring due to the slow change with the other torque not slowly changed.
