Title:
POWER OUTPUT DEVICE
Document Type and Number:
Japanese Patent JP3173397
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power output device of consuming electric energy in a battery means and preventing an overcharge in the battery means without having an influence on an output of power to a driving shaft, along with no increase in the number of parts.
SOLUTION: When a remaining capacity of a battery 94 is over a given set value near to a full-charge state, one motor not operated is selected out of a clutch motor 30 or an assist motor 40 on the basis of a connection states of a first clutch 45 and a second clutch 46. Then, only a d-axis current (field current) is fed to three-phase coils of the motor not operated. Then, the electric energy in the battery 94 is consumed as a copper loss in the motor. Since a q-axis current (torque current) is not carried in the three-phase coils in the motor, the torque is not developed in a driving shaft 22 or a crank shaft 56, and thereby there are no influence on an output of power to the driving shaft 22.
