<P>PROBLEM TO BE SOLVED: To reduce a burden for output of second motor/generator. <P>SOLUTION: A driving control device has a power dividing mechanism 40 which includes: a sun roller 41 where a rotary shaft 21 of a first motor/generator 20, an output shaft 11 of an engine 10, an output shaft 50 towards a driving wheel side and a rotary shaft 31 of a second motor/generator 30 are connected respectively; a carrier 43; a first disk 44; a second disk 45; and a planet ball 42 which can carry out power transmission through a contact part between each of the sun roller 41, the first disk 44 and the second disk 45, and is held at the carrier 43, and can change a first planetary gear ratio ρ1 obtained by dividing the rotation speed of the first disk 44 with the rotation speed of the sun roller 41 and the second planetary gear ratio ρ2 obtained by dividing the rotation speed of the second disk 45 with the rotation speed of the sun roller 41 by changing a tilting/rotating angle of the planet ball 42, and enlarges the second planetary gear ratio ρ2 so that the rotary torque of the second motor/generator 30 becomes small. <P>COPYRIGHT: (C)2012,JPO&INPIT |
