<P>PROBLEM TO BE SOLVED: To transmit torque from an internal combustion engine and a motor generator to wheels, in the power unit of a hybrid vehicle of the type in which a forward/reverse switching mechanism is further added to a mechanism capable of changing transmission ratio continuously according to the relative difference in rotation between the internal combustion engine and the motor generator, without requiring the motor generator to produce high rotational speed when the travel direction of the vehicle is changed. <P>SOLUTION: The forward/reverse switching controller determines whether switching of the direction for transmitting rotation of a forward/reverse switching means will be performed, depending on whether the number of revolution of the motor generator exceeds a predetermined value when the present travel direction of the vehicle is different from a direction indicated by a vehicle travel direction indicating means. <P>COPYRIGHT: (C)2008,JPO&INPIT |
