<P>PROBLEM TO BE SOLVED: To provide a power transmission mechanism for a hybrid vehicle for improving fuel consumption by reducing a loss caused by driving of a generator motor uselessly in running the vehicle under ordinary condition, and effectively utilizing regenerative energy in deceleration, and for improving controllability in acceleration and deceleration. <P>SOLUTION: The power transmission mechanism 1 of a hybrid vehicle includes: an internal combustion engine 2 that outputs power; a power generation motor 3 that carries out power generation and outputs power when the power is input; and a control means (hybrid ECU 6) that selects and then controls the internal combustion engine 2 and the power generation motor 3 as a driving source for running. The power transmission mechanism 1 of the hybrid vehicle also includes a power connection/disconnection mechanism 4 that connects the power generation motor 3 with a power transmission route for transmitting the power and then disconnects the power generation motor 3 from the power transmission route, or vice versa, intermittently. The control means 6 activates the power interruption mechanism 4 and then deactivates it, or vice versa, intermittently with reference to at least one of information on road conditions, information on traffic conditions and information on vehicular conditions. It is preferable that the control means 6 separates and controls the power interruption mechanism 4 when the continuation of ordinary running is expected. <P>COPYRIGHT: (C)2011,JPO&INPIT |
