Abstract
A hybrid vehicle of the present invention includes a brake that fixes a sun gear shaft linked with a sun gear of a power distribution integration mechanism , and a clutch that mechanically connects a drive shaft with a motor MG and releases the mechanical connection of the drive shaft with the motor MG . In the case of a relatively low vehicle speed, the power of an engine is subjected to torque conversion by the power distribution integration mechanism and motors MG and MG and is output to the drive shaft , while the brake is in OFF position and the clutch is in ON position. In the case of a relatively high vehicle speed, on the other hand, the power of the engine is directly output to the drive shaft , while the brake is in ON position and the clutch is in OFF position.
