20090093335 | TRANSMISSION AND POWER TRANSMITTING SYSTEM - A transmission includes: a plurality of rotating elements interposed between a driving source and an output portion; a rotating member that rotatably supports one of the rotating elements and is formed at a radially outer portion thereof with a plurality of recesses or protrusions; a support member having a surface, that is facing the rotating member, and a plurality of protrusions or recesses that are formed in a radially inner portion thereof and engage with the recesses or protrusions of the rotating member, the rotating member being mounted in the support member such that the rotating member is not able to rotate; and a friction producing mechanism that is provided between the rotating member and the above-indicated surface of the support member and is arranged to produce a frictional force between the rotating member and the surface of the support member. | 04-09-2009 |
20090105035 | PLANETARY GEARSET - A planetary gearset provided with a sun gear, a ring gear, and a carrier that rotatably retains a plurality of pinion gears arranged between the sun gear and the ring gear as elements, in which one of the elements is made a fixed element and one of the other elements is made a rotating element, and which transmits torque between that rotating element and an external member provided in a location eccentric with respect to that rotating member. The planetary gearset is constructed such that the fixed element is movably retained in the direction of a load from the transmission of torque between the rotating element and the external member, and the load from the transmission of torque between the rotating element and the external member is received by a fixed portion that rotatably retains that rotating element. | 04-23-2009 |
20100094498 | 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. | 04-15-2010 |
20100185351 | HYBRID VEHICLE - A hybrid vehicle includes an engine that is an internal combustion engine, a motor generator that is a rotating electric machine used together with the engine for driving the vehicle, an output shaft transmitting power to a wheel, a transmission member coupled to the output shaft, a power split device splitting the output from the engine to the motor generator and transmission member, a detection device detecting irregularities on a road, and a control unit reducing, when the detected result by the detection device indicates generation of periodic torque variation at the output shaft, the output from the engine based on the detected result. Accordingly, a hybrid vehicle that does not require a torque limiter is provided. | 07-22-2010 |
20100262322 | CONTROL APPARATUS OF VEHICLE DRIVE APPARATUS AND PLUG-IN HYBRID VEHICLE - A hybrid control controller stores vehicle speed influence values that have been set according to vehicle speeds, a first threshold value of a sum value of the vehicle speed influence values, a second threshold value lower than the first threshold value, and an engine start reference vehicle speed, and during EV running, sums the vehicle speed influence values from moment to moment. The hybrid control controller starts the engine in a case where the sum value is no less than the first threshold value, and in a case where the sum value is no less than the second threshold value and the vehicle speed is no more than an engine start reference vehicle speed. | 10-14-2010 |
20130054064 | CONTROL DEVICE OF VEHICLE POWER TRANSMISSION DEVICE - 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. | 02-28-2013 |
20130073134 | VEHICLE CONTROL DEVICE AND VEHICLE CONTROL METHOD - HV-ECU executes a program including a step of executing rattling noise avoidance control when an engine operating point falls within a rattling noise producing range and when a requested torque Treq | 03-21-2013 |
20130190962 | POWERTRAIN, METHOD FOR CONTROLLING POWERTRAIN, AND DEVICE FOR CONTROLLING POWERTRAIN - A powertrain includes: an engine provided with a plurality of cylinders; a first motor generator coupled to an output shaft of the engine; and an ECU for controlling them. When misfire in the engine is detected, the output shaft of the engine is rotated by driving the first motor generator with ignition and supply of fuel to the engine being suspended. | 07-25-2013 |
