<P>PROBLEM TO BE SOLVED: To improve responsiveness of a continuously variable transmission. <P>SOLUTION: An engine 13 is connected with the input side of the continuously variable transmission 11, and a motor-generator 15 is connected with the output side of the continuously variable transmission 11 through a clutch 14. Moreover, a driving wheel 17 is connected with the motor-generator 15. In the EV mode in which the clutch 14 is released, the hydraulic fluid is supplied from an electric oil pump 47 to the continuously variable transmission 11. As a result, outflow of the hydraulic fluid from a primary oil chamber 23 and a second oil chamber 25 can be prevented even in the EV mode in which an oil pump 46 stops along with the engine stop, and a continuously variable transmission 11 can be quickly operated when a shift is requested. <P>COPYRIGHT: (C)2013,JPO&INPIT |
