<P>PROBLEM TO BE SOLVED: To provide a speed change control device for a hybrid vehicle without giving a sense of incongruity to a driver in changing speed. <P>SOLUTION: The hybrid vehicle includes: a power distributing device where an engine is connected with a first rotating element, a first motor generator is connected with a second rotating element, and a drive shaft is connected with a third rotating element; a second motor generator for transmitting drive power to the drive shaft; a stepped transmission, interposed between the drive shaft and the second motor generator, for releasing a clutch in changing speed; and a battery for charging and discharging between the first motor generator and the second motor generator. The hybrid vehicle further includes a speed change control means for reducing distributed torque of the engine and the first motor generator before changing speed, raising the distributed torque of the second motor generator, and then releasing the clutch to perform speed change when the battery is limited to be charged and the speed change of the transmission is requested. <P>COPYRIGHT: (C)2010,JPO&INPIT |
