20130245875 | CONTROL DEVICE OF VEHICLE DRIVE DEVICE - A control device of a vehicle drive device includes: a hydraulic power transmission device including an input-side rotating element to which power from an engine is input and an output-side rotating element outputting power to drive wheels; a first electric motor directly or indirectly coupled to the input-side rotating element; and a second electric motor directly or indirectly coupled to the drive wheels. | 09-19-2013 |
20140179477 | VEHICLE - A vehicle using a first MG, a second MG, and an engine as drive sources includes an electric oil pump, a mechanical oil pump driven by power of the engine, and a hydraulic circuit. The hydraulic circuit includes first oil passages for supplying oil to the first MG, a second oil passage for supplying oil to the second MG, a switch-over valve capable of switching over states of communication of the first oil passage, and a switch control valve that outputs pilot hydraulic pressure to the switch-over valve. States of the switch-over valve are switched over in accordance with hydraulic pressure from the switch control valve and hydraulic pressure from the mechanical pump. | 06-26-2014 |
20140342872 | HYBRID VEHICLE POWER TRANSMISSION DEVICE - A power transmission device of a hybrid vehicle comprises: an electric differential portion having a first rotating element coupled to an engine, a second rotating element coupled to a first rotator, and a third rotating element coupled to a second rotator, the second rotator being disposed in a power transmission path including the third rotating element between the engine and drive wheels, the second rotator having a rotor shaft interposed in series in the power transmission path, a rotor of the second rotator being fixed, and making up a portion of the power transmission path. | 11-20-2014 |
20140358349 | CONTROL DEVICE FOR VEHICLE - A control device of a vehicle includes a first electric motor; a differential mechanism having a rotating element coupled to the first electric motor, a rotating element that is an output rotating member coupled to drive wheels in a power transmittable manner, and a rotating element coupled to a non-rotating member by actuation of a lock mechanism; and a second electric motor coupled to the drive wheels in a power transmittable manner. During motor running for running with output torques from the first electric motor and the second electric motor used together in an actuated state of the lock mechanism, a drive torque shared by the first electric motor is made smaller in a requested drive torque when a rotation speed of a pinion making up the differential mechanism is higher. | 12-04-2014 |
