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.

Control device of vehicle power transmission device

A control apparatus for a hybrid vehicle to permit charging of an electric-energy storage device with an electric energy supplied from an external electric power source provided outside said hybrid vehicle, while said hybrid vehicle is held stationary; and to operate an engine for operating a lubricant supply device to supply a predetermined amount of the lubricant, during charging of said electric-energy storage device by said external electric power source, irrespective of whether a count of said motor running counter has reached a predetermined upper limit, and to reset said motor running counter.

Control apparatus for hybrid vehicle

When at least one of a condition under which a parking brake is activated, a condition under which a shift lever is shifted to a parking range, a condition under which a shift to the neutral range is executed, and a condition under which a drive termination operation is executed is satisfied during an EV travel mode, a carrier shaft provided coaxially with a crankshaft is rotated by a motor generator, and a cumulative value of a travel distance counter obtained when an engine is stopped is reset.
