<P>PROBLEM TO BE SOLVED: To provide a hybrid driving device provided with two electric motors capable of performing continuously variable transmission and preventing the lowering of energy recovery efficiency without causing the lowering of transmission efficiency in a high vehicle speed/low driving force region. <P>SOLUTION: In this device, first and third driving and transmitting states are created in a state that an input shaft I is connected to a first rotation element of a planetary gear device, the first electric motor MG1 is connected to a second rotation element, and an output shaft O and the second electric motor MG2 are connected to a third rotation element to achieve transmission by the planetary gear device and three frictional engagement elements B1, C1 and C2. A second driving and transmitting state is created in a state that the input shaft I, the output shaft O and the first and second electric motors MG1 and MG2 are independently connected to four rotation elements of the planetary gear device, respectively. <P>COPYRIGHT: (C)2007,JPO&INPIT |
