Abstract: 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.

Abstract: In a planetary gear unit 120, a planetary carrier 123 is linked with an engine 150, a sun gear 121 with a motor 130, and a ring gear 122 with a motor 140 and an axle 116. A clutch 160 is disposed between the planetary gear unit 120 and the motor 140 to connect and disconnect the planetary gear unit 120 with and from the motor 140. A brake 162 is also provided to constrain the ring gear 122 in a released position of the clutch 160. The state of coupling the clutch 160 attains the structure of a parallel hybrid vehicle. The state of releasing the clutch 160 and activating the brake 162 to constrain the ring gear 122 attains the structure of a series hybrid vehicle. The technique of the present invention changes over the drive mode according to the driving state of the hybrid vehicle, thus ensuring an efficient drive that takes advantage of the characteristics of the respective drive modes.

Abstract: A hybrid vehicle 20 may run with only the power from a motor MG2, while an engine 22 is at a stop. In this state, the control procedure drives a motor MG1 to rotate a crankshaft 26 at an idling engine speed for a predetermined time period, when at least one of an observed oil temperature in a sump 62, an observed temperature of a motor MG1, an observed temperature of another motor MG2, an observed revolving speed of the motor MG1, and an observed revolving speed of the motor MG2 is not less than a corresponding preset value. Rotation of the crankshaft 26 at the idling engine speed results in driving an oil pump 60 to feed a supply of lubricating oil to mechanical part of the power output apparatus including a power distribution integration mechanism 30.

Abstract: At a time of backward movement, a ring gear shaft, and thus a front axle, is disconnected from a planetary gear by a clutch, and a carrier and a ring gear, and thus, a crank shaft and a sun gear shaft, are connected to each other by the clutch, whereby a hybrid motor vehicle is constructed as a series-type hybrid electric motor vehicle, thereby outputting a torque in accordance with a depressed amount of an accelerator pedal to the front axle and a rear axle by a motor MG2 and a motor MG3 at a suitable torque distribution for backward movement. When a state of charge of a battery is small, power is generated by a motor MG1 using a power obtained by driving an engine so as to be supplied to the motor MG2 and the motor MG3.
