    Abstract: PROBLEM TO BE SOLVED: To provide high torque when power in the reverse direction to the rotation direction of an output shaft of a prime mover is outputted to a driving shaft using power outputted from the prime mover. SOLUTION: This power output device 10 comprises an engine 50, a clutch motor 30 connected with a crankshaft 56 thereof, and an assist motor 40 connected with the crankshaft 56 or the driving shaft 22 through a switching device 80. When the vehicle moves backward, the operating characteristic of the engine 50 is set to the characteristic on the low toque side instead of the characteristic (efficiency is prioritized) in forward movement, and torque Tm larger than and reverse to the engine torque Te is outputted from the assist motor 40. Thus, the electric power is regenerated by the clutch motor 30, high torque is outputted to the driving shaft 22, and the the vehicle can be moved backward. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide power output equipment having high efficiency and small in size. SOLUTION: A power outputted from an engine 50 to a crank shaft 56 is transmitted to a rotating shaft 57e with the number of revolutions increased and the torque decreased by a step-up gear 57 fitted to the crank shaft 56. A driving shaft 22 of a vehicle running at a constant speed is operated generally with higher revolutions and a lower torque than operating points where the engine 50 is efficient and, therefore, by making the power outputted from the engine 50, the one with the high revolutions and the low torque by the step-up gear 57, the electric energy interchanged between a clutch motor 30 and an assist motor 40 on the occasion of conversion of the torque by the two motors 30 and 40 can be made small. As the result, the loss in the two motors 30 and 40 can be lessened and small-sized motors can be used for them.

    Abstract: PROBLEM TO BE SOLVED: To reduce maximum load capacity of an assist motor, and also reduce maximum current value of an inverter circuit for driving the assist motor. SOLUTION: A control unit 90 sets a WOT line L2 as a boundary of an overdrive area and an underdrive area, when a coupling condition of an assist motor 40 is an overdrive linking condition (S104). The control unit 90 determines a desired coupling point of a drive shaft, namely an outer rotor shaft 35 from a required output (S106). When the desired operating point is in the underdrive area, the unit selects the WOT line L2 for maximizing a torque of an engine 50 as an operating line of the engine 50 (S116), and marks a switch flag from the overdrive coupling to the underdrive coupling (S118). Thereby, the overdrive coupling is switched to the underdrive coupling, and when the operating point of the drive shaft, namely the outer rotor shaft 35 is in the underdrive area, the WOT line L2 is used as the operating line of the engine 50.

    Abstract: PROBLEM TO BE SOLVED: To make the distribution of the drive power outputted from the front and rear axles of a four-wheel drive hybrid vehicle to be variable. SOLUTION: A four-wheel drive hybrid vehicle is constituted in such a way that part of the drive power outputted from an engine 150 is transmitted to a front axle 116 via a clutch motor, and the remainder is regenerated as electric power. The regenerated electric power is used for driving a motor which is coupled with a rear axle. In the hybrid vehicle, a speed change gear is interposed between the clutch motor and front axle 116. The speed change gear is constituted of a planetary gear 210 to which a ring gear 212 is fixed and a clutch 222. The front axle 116 is coupled with a sun gear 211, and the rotating shaft of the clutch motor is selectively coupled with a planetary carrier 213 or the sun gear 211, depending upon the switching a clutch 222. The rotating shaft is coupled with the carrier 213, while the vehicle runs normally and with the sun gear 211 while the vehicle is accelerated. Because of this means, the distribution of the drive power outputted from the front axle 116 can be made larger while the vehicle is accelerated.
