<P>PROBLEM TO BE SOLVED: To provide a control device of hybrid vehicle, which can appropriately select a variable speed level and thereby improve fuel consumption of a hybrid vehicle. <P>SOLUTION: In the control device, an integrated fuel consumption map which provides the integrated fuel consumption of the hybrid vehicle by variable speed levels of a transmission mechanism is memorized, the integrated fuel consumption map is corrected in accordance with a difference in the mechanical efficiency of power transmission among several variable speed levels of the transmission mechanism, the integrated fuel consumption map is corrected in accordance with at least either one of the power generation efficiency of an electric motor when regeneration is conducted by the electric motor using a part of the power of an internal combustion engine or the driving efficiency of the electric motor when the internal combustion engine is assisted by the electric motor, and the variable speed level of which the integrated fuel consumption is the smallest is selected from the several variable speed levels in accordance with the corrected integrated fuel consumption map. <P>COPYRIGHT: (C)2013,JPO&INPIT |
