POWER TRANSMITTING DEVICE AND FOUR-WHEEL DRIVEN VEHICLE AND POWER TRANSMITTING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To suitably distribute the output power of an engine to two shafts by providing a second power control means for controlling the power output to a second output shaft by controlling a second electric motor based on the power which is input to or output from a first electric motor in an electric state by a first power control means. SOLUTION: Since the aiming engine torque Te and engine speed Ne of an engine 50 is set, the engine torque and engine speed of an engine 50 is controlled such that the engine torque and engine speed of an engine 50 become the setting values. A direction is transmitted to EFIECU by a control CPU to gradually adjust the torque of the engine to Te and the engine speed to Ne. In an assist motor 40, the driving shaft 22B for the rear wheels is given torque by power regenerated by a clutch motor 30 in proportion to the deviation of the rotational speed of the crankshaft 56 of the engine 50 from the rotational speed of the inner rotor 34 of the clutch motor 30.
