  • Patent number: 9260110
    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.

  • Patent number: 8554400
    Abstract: 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.

  • Publication number: 20120101676
    Abstract: It is provided a control apparatus for a hybrid vehicle provided with an engine and an electric motor serving as a vehicle drive power source, a power transmitting system for transmitting a drive force of said vehicle drive power source to a drive wheel, an electric-energy storage device for storing an electric energy to be supplied to said electric motor, and a lubricant supply device which is operatively connected to said engine and operated by a rotary motion of the engine to supply a lubricant to at least a portion of said power transmitting system, the control apparatus being configured: to permit running of the hybrid vehicle in a motor drive mode in which only said electric motor is operated as the vehicle drive power source, with the electric energy supplied from said electric-energy storage device while the rotary motion of said engine is stopped; to operate a motor running counter in said motor drive mode, to count continuation of said motor drive mode without the rotary motion of said engine, and t

  • Patent number: 7832512
    Abstract: 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.
