摘要：<P>PROBLEM TO BE SOLVED: To enhance power transmission efficiency in an extensive operational area by adequately changing a state in which a first element of a power distribution and integration mechanism is coupled to a drive shaft and a state in which a second element is coupled to the drive shaft. <P>SOLUTION: In a hybrid car 20, an engine 22, motors MG1 and MG2, and a transmission 60 are controlled so that the power based on the requested torque Tr* is output to a drive shaft 67 with the engine speed adjustment of matching the speed Ne of the engine 22 with the transition speed (γt/k×V) based on the upper stage side transition transmission gear ratio γtu(n), i.e., the practical transition transmission gear ratio, and the transition from the n-th speed change state to the (n;1)-th speed change state when the requested transmission gear ratio γr as the requested value of the transmission gear ratio between the engine 22 and the drive shaft 67 reaches the lower limit transmission gear ratio γlim(n) or below, which is the value equal to or lower than the n-th transition transmission gear ratio γt(n) while the n-th speed change state is set by the transmission 60. <P>COPYRIGHT: (C)2008,JPO&INPIT
